Xoom Screen and Battery performance vs ipad 2 - Xoom General

My wife uses ipad2 and i am using xoom. Noticed some glaring performance issues for the battery and the screen:-
1. The battery on the ipad2 can last twice as long as the xoom. I can get 3 days use of battery from the ipad2 compared to the xoom for about the same usage. When i use the xoom for about 5hours - mainly to do basic web serving, read books, with 3G turned on (rest of wireless turned off), i have about 40% battery left after 24hours. That does not seem normal to me, battery reports that the battery juice is used by the screen mostly (80%)...but my screen brightness is less than 30% level.
2. The you tube HD video clarity on the ipad2 is definitely more superior in color richness , clarity and sharpness. Turning up the screen brightness to 100% and activating the higher video quality in the xoom helps a bit but the improvement just makes a dent. I have read that the ipad screen is better...but what i see is a clearly superior ipad screen performance.
I almost hate to say this....ipad2 is a winner as far as the battery and screen quality is concerned. Or my xoom is a dud and i should bring it back to motorola?
thanks

P/s - Saw this article on the xoom screen performance from gizmodo.com.au/2011/07/best-tablet-display-ipad-2-just-got-dethroned. Looks like i am better of reading books with xoom and watch videos on the ipad2.

Honestly the xoom's screen is good enough for watching videos. But to say your not going to use it for video's because of a small difference in the screen.(I've compared them side by side) Why not read books on the ipad?
My xoom lasts me 4 days on battery browsing and playing games for 4 hours a day. But I'm using wifi only.

Can the ipad2 install 3rd party music players?
Use Xbox controllers?
Mount cameras?
Use SD cards to play friends music?
As well as many other features.
Both have strong and weak points, just pick the one suited to you simple.

Does the ipad run android? Nope

Hi,
I got the xoom for the reasons you have highlighted and am thankful to the XDA community for the support and the hacks. It makes the experience so much more fulfilling .
Ipad2 plays the youtube by default in HD mode while in the Xoom, you have to select this play mode. Having realized this solved the problem that was borne out of my ignorance.
I hope the Tiamat 2.1 improves the Xoom battery life, i am charging it almost daily now since it drops to below 40% after a day of use.

I think he's trying to be sarcastic, lol.
If you're doing anything other than listening to music, the Xoom will give +/- ten hours of battery life. That's pretty good. I charge at night on my speaker dock and use it as my alarm clock. It's ready to go in the morning and lasts through the day with battery to spare.
Use SetCPU or CPU Master to set battery saving profiles if rooted with custom kernel/rom.

So you get 16 hours of battery life out of your xoom? Honestly, sell it back to Motorola for half a million or so, so they can find out how you doubled the normal battery life.
Sorry, I really like my xoom and am a Android "Fanboy", but we should at least try to be realistic.
I don't get what all the fuzz is about anyway. The Ipad2 has a better battery life, which is even written down in the specs. And that the xoom's screen is **** (relatively, considering the price class) has been mentioned right from the start. So, nothing new to see here

Tiamat 2.1 ROCKS
Hi,
Using Tiamat 2.1 with
1. Used Set CPU to increase to 1.5Ghz (settings = ondemand). Performance increase very noticeable and quadrant score has increased from 1800 to 3500!
2. Battery life has also improved, half a day use drops about 20% but will take me a few days to test this out for a fact. I suppose this because Tiamat has cleaned out the bloat ware Thanks ROM Team Tiamat! Also used Auto Memory Killer (got this advice from Xoom Heaven thread, Thanks diablo2224!). And all this with 1.5Ghz CPU setting!
I support android, use SGS2, SGS1 (wife using this) and Xoom. XDA is a great place where the majority of the views are objective and useful for the reader, to make informed decisions.

Lol seriously such a hassle to plug it in over night! Mine runs a couple days with heavy use thanks to rooting it and running setcpu...doing this to solve Androids battery guzzling from the factory issue I have a tab that can outlast the iPad, but more importantly excels in several other categories. When the source code comes out things will only get far better...this is a device for real techies...you want a pretty screen and the internet without ever getting the true potential with your device...buy a fadPad
Oh and stock I never had a problem with a full day battery life on this thing which is really all you need, but if you put in the twenty minutes of extra work you could have way better battery life...as far as the screen crispness it is subjective...some folks swear the iPad is better some say xoom has better quality but darker screen...the difference is minimal in my opinion and using better third party players helps...rant over

I'll be the 1st to admit that the iPad2 has a better display than the Xoom, but hell so do most of the other recent android tablets out there. I bought iPad2's for my daughters and I could never move to the darkside. I rely too much on google's free tools, being on the road so much I literally could not live without google maps and it's free voice navigation.
Make no mistake, I'm just as disappointed in the Xoom's display as anyone else and the still absent LTE upgrade (I know it's finally coming) have turned me off from Motorola hardware completely. Since VZW essentially gave me a 4G hotspot and allow me to use my Xoom as a wifi only device, I can't really complain anymore. I won't be leaving Android anytime soon, especially for iOS

Yeah my real gripe is with motorola releasing their device too early...I would have gone HTC if they had a comparable device but they don't as of yet...oh well just means I had to hack it a little more than planned...

Improved battery life
Hi,
The battery life with the Tiamat 2.1 has improved. Instead of dropping down to 40% after day use, now it is 70%. My usage will not be identical daily but the improvement is significant, very pleased with it.
Tiamat ROM Team ROCKS!

Nexus One Battery Life vs iPhone 3gS/4G

Earlier this year, I was a huge Android fan. I had a rooted G1 with a different firmware every week. My Dream ended when I realized that the battery was lasting me not more than 5-6 hours, even with very light use. This was after swapping out batteries/phones. Also, for working out, I needed a good music player. Android's default one needed a LOT of improvements.
So, when my friend brought over his iPhone, I decided to give it a try. I bought an iPhone 3GS from craigslist. Jailbroke and Unlocked it. The battery was lasting me more than a day, even after watching more than an hour of TED.com talks, and listening to an hour of music. The ipod functionality was amazing with the volume/music controls in the earphones.
Then, I accidentally updated my phone to the latest firmware... which cannot be unlocked. So I'm back to using my G1.
So, the question still stands.. Is Froyo on Nexus One better in battery performance and iPod functionality of iPhone 3GS. Especially with the upcoming iPhone 4G, we can be sure that Apple will increase the battery life of iPhone (as they've done with all previous updates)?
I get a lot better battery life with Froyo then on my 3GS to be honest. Also, as far as the music functionality goes, why do you think its so bad? If you dislike the interface, then you can download a alternate option from the Market. But for me, as long as it plays the songs, view/edit playlists and browse the music I am good to go.
i got slightly less battery life from my Nexus with 3G turned off compared to my jailbroken 3GS.
normally ended up with about 10% less battery at the end of the day compared to my IPhone and similar usage.
the Nexus was stone stock.
Thanks for the replies...
To answer the question about music interface... I think the ipod interface is much smoother than anything i've seen in Android (please suggest something in case I might've missed it). As I mentioned before, I use the earphone controls A LOT.. and am not sure if Nexus One will offer the same functionality.
Battery life is a huge issue for me. As I said, my usage on iPhone was pretty heavy. Let me lay it out here -- this is with Edge.. Push On.. and Location On.
- 1.5 hrs music
- 1 hr video (Ted talks podcast)
- 1.5 hr phone calls
- 2 hr games
- 3 hr Wifi on
With this kinda usage, my iPhone would have 15-20% battery left by end of the day (midnight usually)...
Does your Nexus One match that or is better?
( I'd love to switch to Nexus, if battery is a non-issue... love the Google integration!)
Battery life is across the board on the N1 for some reason. People will have the same set up and get very different kinds of battery life. I know I've never been happy with the battery life of the phone.
A good music player is ³. Cubed. I like it. I recommend the Nexus One if you get the 2 batteries and external battery charger for 20 bucks deal off of eBay. Maybe life will increase but until then having an arsenal of batteries solves my problem.
Ok, I guess I'm back to 8th grade, basic math. Let's calculate. And because you could have just looked in the specs and done the math yourself, I'm not going to look there, and if I bring the wrong numbers - so be it.
1.5 hr of music is almost nothing. Music is optimized for very low battery usage - 20 hr of listening or so. Let's say, 5% off battery.
Wifi on is nothing. You can keep it on for as long as you like, you actually save battery - it turns off 3G/HSDPA and uses WiFi data.
1.5 hr phone calls out of ~6 hours spec ~= 25% battery off.
1 hr video out of 5 hr spec ~= 20% off.
2 hr games are quite destructive. Both CPU activity and display. Let's say, another 25-30% off.
You're left with approx. 15-20%. Surprised?
Oh wait... It figures, no? Do you think one of those systems is going to be significantly inferior in terms of battery life? You don't think Samsung and Qualcomm know their stuff well enough?
Ah, and the difference is going to show if you use Android power and load it with zillion auto-updating and auto-syncing widgets, that'll chew on your CPU idle time and use up your network power.
[edit] That's exactly the reason for varying battery life between users, as the poster above noted. People use their phone differently, and unlike iPhone, it can perform a lot of things simultaneously, without you even noticing (it's enough that you installed auto-syncing widget and made it sync once in 5 min with a good amount of data, for example) - and it'll cost you battery life. Control what you're running, and you'll get more out of the battery.
I came from an iPhone 3G to the Nexus One and the battery life does seem worse. it's always hard to compare because I do more with my Nexus One. My gut feeling though is even if my usage is similar to what I would have done with my iPhone, the Nexus One just uses more power. Part of that may be the higher res screen. Battery usage almost always shows the display as the biggest user of my battery.
I recently have been having worse than normal battery life. I'm not sure if it's due to upgrading to Froyo or if it is because I turned Latitude on. If it's Latitude, then it's really frustrating that the Battery Usage area doesn't list Latitude as using my battery. Kind of makes that a pointless feature if things just get hidden under names like "Android System".
I also agree with you on the Android music player. I use it, and it's not terrible, but the iPod app on the iPhone is just much easier to quickly get to the music you want to play. Also the Genius features are really well done. Someone suggested Cubed. I found it gives a really good first impression but once you use it you realize it's actually just flashy and it functions awful. As far as I can tell there's no way to quickly find and play a single song with it.
Battery life for 3gs is better than nexus..
For my usage the battery life on Froyo is about twice as good as the battery on 3GS. Granted, I listen to slacker radio while browse websites for about 2 hours a day and the multitasking on android is much more natural than the jailbreak alternative.

I am not altogether sure you aren't just trolling. There isn't any way to give a definitive answer to this question, but I'll give you my experience.
No new N1 user is going to say he gets good battery life. You won't want to shut the screen off for the first week.
Now, I can get a day and a half out of my battery on a stock rom if I don't sync absolutely everything frequently, I use wifi when it's available, keeping radios I am not using off and basically, being mindful of power use. I use it frequently, but not constantly. And if I am away from a charger, I have an inexpensive spare battery that I can change all by myself without any special tools all the while sending SJ a FU via ESP.

Lemme get first thing straight.. I have NO intentions of trolling No harm intended. When I bought the iPhone, EVERYONE I know was immensely surprised. I was (and still am) a spokesperson for Android. I love the apps. Maybe thats a reason that we all install so many widgets/apps which use data.... So many are available for free!! and awesome ones too.. for example.. I'd kill for the News and Weather app to be in iPhone.. but its not...
As I said in the original post.. a big chunk of my criteria is battery life.. second big chunk is music... I guess I'm sad that no Android phone yet can beat the battery life that an average iPhone user gets... I was hoping by releasing Froyo, google would change that (hence this thread)...
Trust me guys.. I live by my gmail.. would rather have everything centered around it... than having apple control my life... just dont wanna carry around extra batteries.. like i had to for my g1...

Something that people keep mentioning but seems to keep getting overlooked when people compare any device running Android to the Almighty iPhone...
Multitasking. Takes. More. Power.
Being able to run 5 or so apps in the background (along with all the automated syncing that's happening on the network-data side of things) is going to drain the battery more than doing one thing at a time on Apple's product.
When your iPhone is able to effectively multitask, come back and then you can compare the battery life.
Quite simply, Android lets you do more than you could ever possibly do on the iPhone platform. It gives you the option (free will - unheard of on the Apple side of things!) to run a handful of apps simultaneously. This, naturally, uses more power as the processor is doing more. This is not rocket science, people. You choose to do more, so accept the power penalty. Or, you can be mindful of your battery usage and manage things appropriately to get a significant battery life improvement. It's your choice!
And if you still don't get enough battery life out of this more powerful, more capable device, as attn1 pointed out, there is absolutely nothing to stop you from getting an inexpensive spare battery that can be swapped into the phone in under a minute (INCLUDING the time it takes to shut down and power back up).
Trying to compare any recent Android device to Apple's iPhone is like comparing my gaming notebook to my old TI-84 graphing calculator - which did get much better battery life than my current Asus G72 notebook.

By 7:14 I'm at 64% charge.
In 2 hours doing what I noted here I lose close to half my battery?! That's laughabad.
It's amazing how all over the place the returns are.
I have owned the following phones in the last three years :
iPhone 2G
iPhone 3G
BlackBerry Bold
iPhone 3GS* (borrowed for 2 weeks to see if I wanted to go back...)
Milestone
Nexus One
I, personally, got the best battery life out of the iPhone 2G - I got three days out of it, consistently. BUT, I did not have an unlimited data plan, I did not use it for mail, I always got apps from the store over WiFi, I never streamed music, video or anything else. I had no RSS reader. I listened to some music, played the OCCASIONAL game, sent some texts and made a few calls.
Next would be the Bold. I POUNDED that thing and ALWAYS got at least 2 days out of it. I would send dozens of SMS, read and reply to at least 40 emails/day, use GTalk with my wife for at least 50 messages a day. I'd read RSS feeds with Viigo.
After that, every single phone on the list requires charging every single day.
On the iPhone 3G, I would do a little surfing, maybe a little video, some emails and some text. Music on the metro coming and going to/from work. Charging every day was mandatory.
On the 3GS, with how App Store had better and better stuff, I killed it (as in forced shut down) 5 out of 15 days - all that with no widgets and no multitasking. I would read Le Monde, do some browsing, read tweets, read emails, make a couple of calls and texts. I started stocking the charge cable at work and in my backpack during my weeks with a 3GS, because it wouldn't make it through a day. Most friends and colleagues who have them do the same.
I received the Milestone in December. I loved it, and really started pounding a phone - 100 GTalks a day, some SMS, all email, NewsRob for RSS, Le Monde, News & Weather widget one we hacked that on there (following the Jan 5 release of the N1), twitter and facebook, browsing. App downloads, widgets left and right, plus CONSTANT dev work, image building, flashing, testing, etc. I would get a day if I took my foot off the gas, but if I pushed it too hard, I would kill it. There were a couple of battery killers that were avoidable but which I didn't avoid from time to time - leaving Qik, the browser on the google homepage (with autolocation on) the Camera or Maps open, then letting the phone go "idle" with the screen asleep keeps the GPS on and would eat the battery in an hour or two. This left me high and dry a couple of times, until I paid a bit more attention. The Milestone got better 3G than any iPhone and worse / less-consistent WiFi.
I picked up a Nexus at the beginning of March. It gets somewhat-to-significantly better battery life than the Milestone. I still have to charge it daily, but there seem to be fewer battery-death bonehead choices that drink the go-go juice and leave you without your electronic BFF. Most of that is probably Android 2.1 and the UV kernels - I noticed that the Milestone was better with 2.1 as well. It also gets 10dbm worse radio reception with the same SIM on the same desk on the same network in the same office. But it gets MUCH better and more reliable WiFi, and that is better still since FroYo. I use it a ton - RSS, chat, SMS, calls, LOTS of browsing, Le Monde, NYTimes in Newspapers Full, lots of games in spare time, Google Listen for Podcasts, Music, Movies, taking pictures and videos and posting them online with Twitter, Facebook, YouTube or Buzz, etc.
The Nexus has one MASSIVE problem, as far as bettery goes - charging it on any computer USB port, and many thrid-party USB charge plugs (AC or DC) is atrocious - hours and hours to get just a few percent. I don't know why - Apple can use 1A from anything, RIM / BlackBerry can come close to 2A. My Milestone would take at least 1A from anything. But the stupid HTC kit won't take more than about 400mA from a computer or a non-shorted USB charger. SOME 3rd party stuff will be exploited up until 1A, as will the charger that the N1 comes with, but if not, you're going to see slooooooow charging.
As far as the music player: I want 2 things - good sound and the ability to pause and skip with the mic button. Every iPhone does this, and so does the N1. The N1 DOES support headset buttons (it's own set comes with them), but I use my Shures with a simple mic adaptor. I almost never see the interface - I put on a playlist and shuffle it. DoubleTwist makes sure that I have the same lists on my iPod touch and my Nexus, so I really don't notice the difference.
If you use the interface a lot, well, then the player on an iPhone is the best there is. I just don't use the interface often enough to make that a selling point.
As far as sound - the Milestone got SIGNIFICANTLY more volume and better sound then any iPhone and a ridiculous amount more than an N1.
Froyo just rocks. I miss a couple of CM features, but there are sooooo many good things baked into Froyo - tethering, copy/paste in received GMail messages, SD card app storage, cloud-stored settings, Flash, incredible performance.
Your Mileage May Vary.

Thanks for the VERY detailed post... And also for clarifying the controls thing... thats awesome that N1 uses the mic button for controls... I use it a lot while running to skip songs...
I'm on the brink with my G1 though... Flashed the latest 2.1 ROM from Cygo.. at first I thought it was fast.. but now its driving me crazy.. its not really the ROM but the phone itself.. will post a video of the experience soon..
So to summarize above posts...
- N1 can give same or better battery life than iPhone... provided.. that we use it well... no crazy widgets/apps which keep using data...
- The earphones button CAN be used in N1 to skip songs.. which is awesome for me...
I think I might order my N1 today itself.. as it's still being sold on google (surprisingly enough).. Who knows once only T-Mobile sells it, if they'll stop offering the unlocked option....
Thanks for all the input guys

Is this really a thread. You use your phone nonstop and wonder why your battery lasts the way it does. You cant compare a psp to a nexus s. Close this thread. You want better battery life stop hogging the phone.

My battery lasts me all day. I play n64oid for an hour a day during lunch at work. That drains 15% to 20% during that time. So yeah, that sounds normal.
Its not a console, built only for games. It has other things running all the time. Also, my old PSP maybe got 5 hours, you must have an extended battery.
Sent from my Nexus S using XDA Premium App
yes this is normal
i can burn through the 100% charged battery in 3~4 hours just browsing the internet alone
the WiFi or 3G is what eats all the power, same goes for the SAMOLED
other devices last even less time, using HTC Desire and similar devices i can drain the battery in 2~3 hours
i always carry extra battery packs with me, i'm a heavy duty user
So, to your answer, no, it is not unusual
High end 3D games also uses a lot of power in the CPU, GPU, SAMOLED and if you are playing online like WOW online for Android, then it will go up even faster.

[Q] Battery life, compared to the Galaxy S
Hi guys,
I used to have a Galaxy S device, and recently purchased a Nexus S, and gave the Galaxy S to my wife.
I assumed that, given the fact that these two devices have a very similar hardware, the battery life would be somewhat similar in both.
However, this is not what I have experienced at all. I basically reinstalled all my apps and home configuration in the Nexus S. The only difference being that I'm using a darker wallpaper now (which is supposed to improve battery life.) The rest is pretty much identical - I basically restored all data from my apps using Titanium Backup (not the system data, evidently.)
I have noticed however that the Nexus S spends a lot more battery than my Galaxy S, especially when the phone is idle. I have everything turned off (GPS, NFC, 3G and Wi-Fi) just as I did with the other phone. Even on Airplane Mode the Nexus S seems to use a lot more battery. Leaving the phone on Airplane Mode at night would barely consume any battery at all with the Galaxy S. The Nexus S does take some hit though.
The battery life is still not a bad one. Especially when compared to LCD phones. However, the Galaxy S is significantly better with stock 2.2.
My question is: Why could this be? Is it because of Gingerbread? Or am I missing something?
Thanks guys!
it's quite the opposite for me
my previous phone was a SGS and it chewed more battery than the SNS

I used to have a Galaxy S device, and recently purchased a Nexus S, and gave the Galaxy S to my wife.
I assumed that, given the fact that these two devices have a very similar hardware, the battery life would be somewhat similar in both.
However, this is not what I have experienced at all. I basically reinstalled all my apps and home configuration in the Nexus S. The only difference being that I'm using a darker wallpaper now (which is supposed to improve battery life.) The rest is pretty much identical - I basically restored all data from my apps using Titanium Backup (not the system data, evidently.)
I have noticed however that the Nexus S spends a lot more battery than my Galaxy S, especially when the phone is idle. I have everything turned off (GPS, NFC, 3G and Wi-Fi) just as I did with the other phone. Even on Airplane Mode the Nexus S seems to use a lot more battery. Leaving the phone on Airplane Mode at night would barely consume any battery at all with the Galaxy S. The Nexus S does take some hit though.
The battery life is still not a bad one. Especially when compared to LCD phones. However, the Galaxy S is significantly better with stock 2.2.
My question is: Why could this be? Is it because of Gingerbread? Or am I missing something?
Thanks guys!

Try to deactivate the GPS and Wifi if you do not use them. You can also use some apps to deactivate 3G access.
I wish Samsung produced higher capacity batteires though.

Was your SGS on 2.1?
I did notice that on Froyo (2.2) the SGS had a much better battery life than on Eclair (2.1). It really made a great difference.
But my SGS on Froyo is consuming a lot less battery than the SNS on 2.3. Especially when the phone is idle (both with everything turned off and set to GSM or even on Air Plane Mode).
So I was wondering if this could be a software issue.

Same with me. I came from a Vibrant, and no matter what ROM I used, I'd lose around 8-15% of battery while sleeping.
With the same settings, and apps now on the Nexus, I lose 1-2 percent while I'm sleeping.
The idle is a lot better for me with the Nexus, and I lose a little bit less while I'm actually using the phone as well.

For me it's exactly the other way around. I assume your Vibrant was on 2.1, right? Cause in 2.2 the SGS does much better. And this is what I would lose: 1-2 percent when on airplane mode for an entire night.
Mind sharing what your config is? I'm on 2.3.3 + Netarchy 1.2.7

I was on 2.2 on the Vibrant. I was mainly using the Axura and Trigger roms.
My config on the Nexus is: Stock 2.3.3 with Launcher Pro.
Go get it exchanged and if it keeps happening, then it's your usage that you need to deal with by getting more batteries or keep it on the charger whenever you can.
I read a lot of threads and posts about battey life on NS and the problems of 100% charging, and most of people declared that the NS has a better battery life of all i9000 series or S series.
Maybe a nokia would suit better, days of battery

there is no problem with "100% charging" it was intentionally made this way to prevent bump charging.
and it does have better battery life. i last 24 hours+

So wait - your PSP has both an extended battery and an extended external battery and you're surprised it lasts longer?
The Nexus S has a 1500 mAh battery in it. The PSP extended is a good 3600 mAh, and external packs can be 4200 or more. So that's 1500mAh for the phone and 7800 for the PSP. The PSP has 5.2x as much battery to power it, so it's logical that it'd last longer.
The phone's also a lot smaller and running power hungry radios for network connectivity, an OS to manage everything and misc. background tasks in addition to whatever game is running.

You're brave saying this in this thread. Most of us now thing you're an idiot...
My Nexus S went 33 hours before last charge. I am a light user though.
To check how you're does, don't use it for at least an hour one time, coming off charge. You should only lose 2-4%. Then check battery usage and see what's taking power when the phone should be doing very little.

Thoughts on YOUR Atrix?

Delete.
i'm very happy with the phone. the only caveat i really have (which a lot of people don't seem to have) is battery life. i get about 13-14 hours with 3-4 hours of display-on time, while others have been reporting double that.
as far as motoblur is concerned, if you just get another launcher and use Titanium Backup Pro to freeze motoblur Home and other services, then you won't even have to think about it.

I should be receiving my Atrix for AT&T tomorrow, this will be a HUGGGGGGEEEEEE upgrade from my measly HTC Hero (Sprint CDMA) that I have modified to the ends of the Earth. I'm in need of more power and amazed at the stuff you can do with the Atrix.
My question to you all, has this phone met or surpassed your expectations? Did it fail to achieve those expectations? Tell me what you think of this phone, I have been reading so many reviews about the phone I feel like I know all technological aspects about the phone as well, haha.
How fast were you to get rid of MotoBlur?

I think I can speak for a lot of people in saying that, as far as the Atrix goes, I am in love with the "potential" this phone has. But as far as meeting those expectations, well, that's something to be debated. There are areas where the dual core shines and other areas it seems it is not harnessing the full power. Then couple that with AT&T's network restrictions and Motorola's lockdown on the device, I'm going to have to say that I am disappointed in the Atrix as of now. That could change if there is a break through in the bootloader or if AT&T gets its act together and starts offering the "High speeds" we were promised. Only problem is though, my 30 days is almost up and I don't know if I can hold onto the phone in hopes of "potential".
Coming from a captivate I love this phone...everything works includi.g the gps. Most of motoblur is gone on my phone. The phone is amazingly fast but does have an occasional hiccup. An unlocked bootloader would turn this into the best available android phone but its one of the top

I'm in the same boat. In terms of hardware, this phone is a beast. I can even live with the screen quality and the terrible camera. But software side, I am really hoping to see a unlocked bootloader or I might be very tempted to take this phone back...

Yeah, I'm high up on the fence because if I do return it I am going to switch carriers as well.
I'm really enjoying it... coming from a Tilt2, it's a major upgrade. Straight out of the box, it's very enjoyable... I'm not dissapointed at all.. it's only going to get better once they get this beast unleashed
Camera is quick and decent.
GPS is amazingly fast...
Browser is snappy and loads everything great
WiFi is a little weak...
and I actually like the screen.. It's not best screen ever made, but it's actually a very nice display.
I was getting terrible battery life, but somehow a hard-reset solved that problem, and i'm able to get more than a day of heavy use no problem.
Just picked up a second one for the wife (coming from an iphone 3g) and she's really enjoying it a lot as well
I like the Atrix. I upgraded from an iPhone 3G. I realize that it's not the best it can be as far as unlocking right now, but it is better than what I had. I only wish I could afford the webtop dock right now for times I'm on the road. Nothing a netbook couldn't fix though.
as far as the battery, it really has to do with what you're doing. I've seen mine go 39 hours over a weekend with normal use, or 16 hours when i'm streaming pandora constantly at work. My building for work also isn't great for signal, so the phone is constantly working for signal, which uses battery.
The other day i did ~5 hours of pandora at work, then fired up the GPS, which was on for ~1.5 hours guiding me, screen on, not plugged in. few phone calls and web use and it was almost dead after 15 hours.
This phone is miles better than the aria i had before it, and it will only get better as more things are updated to take advantage of the tegra 2 platform. Won't matter if this phone gets cracked or not, it will get better and better for a while either way.

Wow... 39 hours. I get about 17 hours of use from it, which is much better than any other smartphones I've ever used so I'm happy... but I can't imagine hitting that number. I do have bluetooth and wifi on all the time.
I like my Atrix, the only problems i see is that the webtop is very limited, but some people over the developer section are working on that, and also the speeds which since T-Mobile was bought it definitely will become faster alongside with HSPA+ and LTE being utilized together. It has lots of potential to run REALLY great, but this is the first phone of its kind, it'll always have problems in the beginning.

and that cuts the battery way down. powering all the radios is a large power drain. I never turn on a radio i don't need, so 90% of the time wifi, bluetooth, gps, etc are off. Mobile data is always on, and i i never try and tell it to revert to 2g.

see... i wish i had that same kind of success.
It's always hard to determine battery life from these posts because people's definition of "moderate" and "heavy" usage differ a lot. This is why it would be nice if the phone had gingerbread where the battery plot actually shows the wake time, wifi time, signal strenth, display on, etc. so people could quote their results rather than just guestimating. The best way to tell is really just display on time since that's pretty much the biggest draw.
Based on my limited testing I can get about 4-5 hours of display on time with auto brightness. The absolute best I could squeeze out of my nexus S is almost 4 hours which is to be expected since it's 1930mah vs. 1500mah. I MIGHT do some battery drain tests before I return the Atrix but I'm not sure... those take time. I know the Nexus S can go about 7-8 hours playing a video while in airplane mode so I'm wondering what the Atrix could achieve.

We do have all those indicators in the Battery manager. I average about 13-14 hours with 3-4 hours of display, unless i'm doing something like streaming March Madness via flash, then it drops to like 7 hours with 2-3 hours of display.
Love it.
Honestly out of all the phones i've had this is the main one.
Screen great looking.
Speed is unreal and I mean like lightening fast :O
The games and apps that work just look and run crazy good!
Camera imo is great not going to replace main cameras but great for stills and videos, would be nice to see the 1080p recording update out soon though
Motoblur stuff which I like :O lol can be frozen and a custom launcher introduced without you even thinking about the motoblur lag.
Battery life is very good I can get a whole day at college 8:30 until 6 heavy usage and still get home with 30-40% left which is great to me
Fingerprint reader is also a great little feature that gets yours friends a little jealous lol
Only thing I don't like is the battery door creaks, I know its nothing major but its just a little annoyance other than that the build quality is great very sleek device!
I'm really bored with my Atrix there's no developement community. You can't do **** with a locked bootloader. Even the iphone is more open than this pos. It's going back tommorrow **** motorola.

I'm a firm believer in the "garbage in, garbage out" philosophy. Yes this phone has one or two legitimate issues (touch screen acting up after x seconds continuous touch), but for the most part is good. How many apps do you have installed? How many do you actually use? Every month i clean out my phone of apps that haven't been used in a couple weeks. I usually see a little bump in battery life each time since less apps are itching to use the data connection or other resources.
how many widgets are you running? I don't really notice it on the Atrix, but on my aria when i had 5 home screens riddled with widgets, it was laggy and slow. Drop it down to 2 screens with a simple setup, and it was snappy.
My point is, most of the time, little issues are probably user generated. I see it all the time with computers. But it's way easier to blame the hardware and software than look for the cause of your problem. again, i'm not down playing the few legitimate issues.
next time i pull a 39hour run i'll post specifics of what i was using it for in the battery thread.
I'm very happy with mine. I don't have much of a desire to put a custom ROM on, so the locked bootloader isn't an issue. The speed of this device is just levels beyond my Nexus One. I can't remember a time so far where I've had any lag. Plus, I don't have to worry about app space the way I did with the N1.

Can't wait for Android battery efficiency to catch up with Apple (small rant)

I own a Transformer Wi-Fi 16GB model. I have owned this since August when i got it for my birthday. I am a Huge android fan boy, recently at work for a thank you gesture, our small dev team received 4 ipad2s as a thank you from management.
I gave the iPad to my fiancée who is pretty much all Apple, (iPhone, mac pro personal and mac pro laptop work and now ipad2)
Last night i just charged both devices to 100%.
On Transformer (no dock) I turned unit off and turned back on and started NO applications.
on ipad2 i did nothing, just charged and removed it from charger first.
Removed Transformer from charger afterwards.
Went to bed at midnight.
woke up at 8am
IPad2 was still at 100%
Transformer - 95%
iPad2 is on latest iOS 5.01
Transformer - is on latest 8.6.5.19 and CPUSpy showed 8 hours of Deep Sleep
So the Transformer is performing as it should battery wise it just pales in comparison to the ipad2 and the battery management shows.
I can use the iPad2 very moderately throughout the week and never have to charge it.
the Transformer i have to charge every few days with the same moderate usage.
just such a bummer, everyone around me is jumping ship to Apple iPhones and iPads
here i am loyal to Android since the G1 when it launched, Mytouch, and my now Samsung Vibrant and Transformer Tablet.
I feel sometimes I am on the losing team. I am and WILL hold out for Ice cream sandwich but if ICS doesn’t perform like it should, I fear I may have to jump ship too.
there is only one thing i hate the most about Android.... the Lag/stutter in apps and home screen swipes.
iOS never does this at all yet every iteration of Android always has some type of frame rate/lag in the system.
yes i know people say Root and get on another rom but why should I have to? ios people don’t have to do that, their OS just works with no lag so why cant Android get rid of their stutter?
ok rant over.
You said you opened it and started no apps. But most apps auto start up on boot. Are you using a task killer?

Not sure a difference of 5% qualifies as "pales" Also Transformer is running multiple apps in background from last use. ipad most likely not running any if not started during this session.
And what is the size of each battery? Did you take that into account?

no i dont use a task killer, i used to on gingerbread andd froyo roms on my phone but after hearing everyone come down with the fire from hell like rain if they found out you were using a task killer on Honeycomb (because honeycomb is supposed to be great at App Management) i dont use a task killer.
the only apps i have on my transformer are the default apps and words with Friends.
also verified while charger was still plugged in and after tf101 was rebooted, that the recent apps or current runnin apps icon showed no apps running (im sure there were some other core android apps running in memory on boot up)
Also iPad2 was rebooted as well. i work in QA at my software company so i pay attention to detail and steps and made sure that both devices were as close to a specific state as possible for this test. in a nice world i would have taken an average with different app scenarios but i didnt feel like it for this personal test.
i the Device is in Deep Sleep then power and app management should be superb and they are for Android but compared to iOS app and power management not so much.
i even loaded PULSE RSS feed aggregator on both devices and the experience is night and day.
nice fast and fluid on the iPad2
on the TF101 with the same feeds and pages, very slugish and laggy and takes more time to draw each individual image in the windows.

Pales when combined with my ipad2 usage over a week compared to my Transformer usage over a week.
i can go over a week with no charge with an iPad2
i cant go more than 2-3 days with out a charge with a TF101
so deep sleep drain with nothing running on a freshly charged device showign 5% drain over night is a positive indicator of where your battery usage is headed with this device.

Im sure this would make a difference throughout a week period (which might be why i need a charge quicker over a week period vs. the ipad)
however i would expect if a device is in deep sleep, that its power/app and battery management would be a little better on par thats all.
i am in no way trying to start a war which i can feel is about to come, not looking for people to come down on me.
I am a true Android devoted user, i just can see the differences between the OS's with small things.
overall the Android experience satisfied so much more than the ipad does which is why i did not keep it and let the fiancee have it but there are some things to be desired from the iPad2 thats all.
Are you honestly *****ing about losing 5% battery over 8 hours? Really? Not to mention you were apparently running CPUSpy, so obviously the tablet wasn't completely idle as you have tried telling us 5000 times.
I sell iPad 2 devices and haven't seen this amazing comparison between the two devices in regards to battery life... My Transformer has lasted longer than the iPad many times so I don't know, every device is different I guess!

i dont care what your running, when you start up android, basically every app you have auto starts up. that is why when your phone starts up you cant just hop on and use it that second. get a task killer. if you want to do a test like this, please do it correctly before ranting to the community.
1. each device fully charged
2. kill all running tasks/apps on each device
3. either do the exact same thing on each device(with the same wifi/3g or whatever) or keep them idle and only check every hour
theese arent the best ways to test but there a whole lot more accurate then what you were doing
No one should be a fan of anything. If you think having better battery life is the most important part of your tablet experience, then get the ipad 2.
For me, the flexibility of android trumps the ipad's battery life. But that's just me.
This is capitalism. We shoudn't have a team mentality here. If you think the ipad suits your needs better, then get it. No drama here.
ok a few problems with that rant first as someone above said you were using cpu spy which uses resources and seccond turning on and off the tablet is the largest and quickest way to lose battery. when i reboot i expect to loose about 3% battery because of the power required so that 5% is perfectly reasonable

Well, you know, I read this, and I can't help but think, and sorry to be rude but... honestly, "who cares????". Are you away from electricity for more than 2-3 days at a time more than once a year? Maybe you like taking week-long camping trips to campsites with no electricity? Maybe? I don't know, but for most people I know, 2-3 days is tons. I just charge mine up overnight, so I never have any downtime due to charging. I'm struggling to see what the big deal is. I mean, yes, 2-3 days is less than a week, but does this really affect you?
Cheers!
I don't really think it's possible to match iOS in battery life...
1. It's real multi tasking on Android, apps consumes more power
2. Android itself is not as efficient as iOS (java vs Objective-C)
I would be skeptical of any device that after 8 hours (assuming you sleep eight hours) still reports 100% battery.

It's not impossible, my captivate does this with certain firmware.
3 points I want to bring up.
1 age of battery. It sounds like you have had the TF longer than the ipad. Which may say that the battery has not been calibrated correctly yet. Also older batteries lose their charge.
2 multitasking. Android actually leaves open apps and processes running. Ios will freeze or suspend them. Android's approach will use more battery.
3 your approach at testing such stats could use some improvement. For one, you could look at the processes running in stead of the apps or the open window list. That list is very innacurate at showing what is actually open.
Lastly imho how long either of these stay on is not really a point I would consider bickering about. For what the TF and ipad do the battery life is well past my expectations. Laptops and netbooks seem like a waste of money now for a good portion of the population in comparison to the computing power, portability and battery life of a tab.

Not until a tablet that I can type without lag, get a full office suite that handles more than one document and store a single file larger than 4GB, lol
These are just some basic stuff on PC.
I own an iPad 1 and a transformer. I use my iPad most days and my transformer about two or three times a week. The iPad still last longer. I don't see why everyone is so defensive about it, the iPad does last longer.
They OP said how he feels and that the didn't want to start a war. I don't understand why every thread is criticized by someone. End mini rant.
I have the OG iPad and the TF. The battery is better on the iPad. However the keyboard dock and additional charge time is nice. We can get into battery size and calibration and how OS runs background apps and battery drain. I'm just saying battery wise I agree with you, but compared to the Galaxy Tab and Dell Streak 7 I'm pretty pleased with the TF battery. I wish I could do that with my Motorola Atrix.
I'm ok with custom roms. They are fun and can help also with battery life.
Best of luck.

I completely with this. My experience with the ipad tells me the same thing. Battery does last longer with the ipad. That said, to me all the advantages of android outweighs (by a lot) the battery disadvantage.
Again, to the op. If you feel battery is the most important thing about a tablet, then I recommend you go with the ipad. I am not a fan of anything. I simply want what's best for everyone.

Did anyone manage to have 40hrs++ battery lifetime?

Dear People,
I am posting this out of big ENVY from my friend's story of his iPh*** 4 battery life with 40hrs ++ of usage (social network on, moderate usage, data always on, bla bla bla) and he still got 20% left of his battery!!!
I was just wondering did anyone managed to experience 40hrs ++ of battery lifetime? My best achievement with my nexus s battery life is
1 day 3 hrs with
MIUI Rom JB 2.8.17
Marmite Kernel 4.3
SmartassV2/deadline
100/1000
Automatic brightness on
Could we EVER achieved 40hrs ++ battery lifetime??? Since Iph*** 4 has practically same specs with Nexus S
It has 1Ghz procs, 512mb ram, 1500mah battery, bla bla bla
Any comments?
A very big advantage of the iphone is the very dim (to my opinion) screen backlight. If you change that to default 1 min instead of 20 on a custom rom, and then change your auto brightness values as well to lower ones your lifetime should increase alot. At least mine does. Also I use Llama to close mobile data after 5 minutes of sleep and then instantly turn it on on unlock. Anyway..we will never be able to win versus apple at some things. They have one operating system made for one device. We got one operating system for like..1 milion devices? That's the same story of console vs pc games.

If you change that to default 1 min instead of 20 on a custom rom, and then change your auto brightness values as well to lower ones your lifetime should increase alot. At least mine does. Also I use Llama to close mobile data after 5 minutes of sleep and then instantly turn it on on unlock. Anyway..we will never be able to win versus apple at some things. They have one operating system made for one device. We got one operating system for like..1 milion devices? That's the same story of console vs pc games.

Never used iOS devices before...So they have those kind of things hey..
I agree with you with the point that their OS was made for one device, while us is for millions
Thanks for the comment
I've been getting pretty excellent battery life lately, will put up a screen shot but got almost 52hrs battery life with wifi and 3g on until it got to about 15% with about 2h 24m screen on time, although this was pretty light usage to be fair.
Using codename 3.3.2 with standard kernal, I turned NFC off and this seemed to help massively although I've also heard the new Maps app has solved some battery drain so not sure which has contributed the most.

52hrs?????? Cant wait for your screenshots man!
You may think the specs are the same, but the hw in the iPhone and power management is still superior. They get a push notification, even while the 3g radio is in idle and almost off (in which it saves more power). It's hard for Android to optimize the power management specially because of that many hardware variations, it's not only the CPU that counts.

Well, thats good to know, but since its the software differences (meaning coding and stuff), surely (i assume and hope) that we could also applied it (somehow) in our devices through tweaks, can we?
IMHO not much is possible since this is older hardware already and a question for how long will Google bother with it. It might be alot of work needed and you gain some insignificant amount of savings.
Would be nice to see some kind of power management tweaks in coming version of Android though.
well its halfly because android works differently and half way because of the hardware.
yes, the hardware is similar, but the nexus screen takes up more power, the processor is not very efficient, and nfc takes up power... also, the 3g radios are honestly HORRIBLE on the nexus s and that might have something to do with it.
but, the software side does make a major impact. iPhones do not multitask like android, which saves power on slower devices like the iphone 4. thats only half of it though, for instance, the iphone 4S has much worse battery life than the nexus s (by far). ROMs make a big difference also, I am very picky when choosing a ROM- if it doesnt have great battery life then I immediately replace it by another ROM that does.
I get on average about 16-20hours pretty consistantly if you are wondering, and I am OK with that as long as it makes it to the end of the day... I wake at 3:30 and normally it does. My advice is to experiment with different ROMs, I would suggest some, but I use an S 4G...
I don't really believe it. My friend has an iPhone and he uses it quit a bit and seems to have to keep it plugged in as much as I keep my phone. I think he said he usually gets about 8 hrs out of it. And the screen is pretty dull compared to mine so that might make a difference to

The iPhone screen is a lot smaller too and that's a big tradeoff.
I always get a chuckle at the iHerd people I see on the bus holding their tiny screen 6 inches in front of their face so they can read it.
If battery life is really a concern get a couple of spare batteries and a charger.

Lasting 40+ hours is easy if you don't use the phone much...
The screenshot was taken on a long weekend a while ago. I was busy during the weekend and didn't use my phone much apart from listening to music for no more than 2 hours.

Thats true, but from the iphone their data was on all the time, mid moderate usage.
But, just like some people said, power managwment chip, the os, makes big differences
