I know its the first day but damn 3 hours and done? I thought evo was bad :[
I don't know what you're doing, but it's wrong.
I bought my phone today at 10:00 AM. First thing I did was charge it all the way. Once I took it off I started getting my apps back, I watched a 720p movie for 10 minutes to see how it worked (freakin amazing... 720p MKV movies out of the box). Browsed the web for 10-20 minutes. Listened to music for 5-10 minutes. Played gamed for about 30 minutes.
Really put the phone through its paces.
I'm at 25% now. 9 hours since unlplugged and screen on time is 1 hour and 34 minutes.
Also remember that you don't get the most out of your battery until you cycle it a few times. I'm running juice defender which also helps a lot.
How did you watch your MKV movie? I am guessing that transferring a 5GB file to the memory card is not optimal.

It's a 720p MKV of Dr Horrible The file is only 800 MB (the movie itself is 45 minutes long). I transferred it over while charging the phone along with my music.
Use the "my files" app and navigate to the movie. When you click it, it opens in the stock movie player which plays MKVs just fine. I was rather amazed.

Take it back get one that works as should
Lol I'm wrong ? I use juice plotter and heavy use and 3 hours later I'm almost at no battery
I'm ok with that as I have been using the hell of it! Love it so far
Yeah...kinda watching the battery myself.
Put it on the charger at 5x% and it hit 100% after charge in about 5 minutes. I turned it off to charge via USB because I knew that couldn't be right. Hit 100% in about 10 minutes. Turned it back on and it's at 65% and charging.
Gonna give this one a few days to condition, though, through normal use and see what happens. The GPS pisses me off that it's completely FUBAR but we'll see if a software fix takes care of that.
The epic drains its batter about 5 to 6x faster then my captivate. It went from 100% at 8 am to dead at 12. I turned off 4g and charged it but now its died again. Died 2 times in 1 day. I am returning it so I cant test more but some people say batters need few days before they work 100%.
I charged mine yesterday morning till the light turned blue and the phone said it was fully charged.
I worked on the phone from 2:00 yesterday afternoon till 11:00 last night...adding, emailing, texting, web browsing and when I was done, it was still at 50%.
My guess is that after there's a real 100% charge in it the battery will condition....just like every other cell phone I've ever used.
So far my Epic battery life is AMAZING. I get so much battery drain on my Evo when I'm not using it. Last night, my Epic was at 14% battery life. I refuse to charge it until I drain it all the way. This morning I woke up and it was at 13%. After 6 hours of idling... 1% drain.
That means my phone has lasted from 11am yesterday until 7:30am today. 2 hours and 10 minutes of screen on time....

You are really not having fun with this phone. I got my phone at 11am put it on the car charger. Made a few calls while on charger (about 40 minutes) at about 2pm the phone said 100% charged and to unplug. I'm coming from a modded WinMo FUZE to this phone' so you know I had to explore the Andriod OS. I was on this phone till about 11pm and still had about 20% battery after downloading apps(Now I finally know how poor winMo marketplace really is.) I know the battery will only get better so I'm fine with it. If I need more I'll get a extended use battery.
Ok well either battery life just blows or it needs time to adjust
I made double and triple sure to 100% charge it and juice plotter is already saying I have only 4 hours left from 100% and just now I've been using it for 45 min and its down to 75%
Another note is that the display seems to be the biggest and outrageous offender of battery consumption. 77% right now
My evo had that issue but once I rooted it and installed a custom rom it leveled out to not have the display use that much juice

See if you can get a replacement. Something isn't quite right there. Im going to get juice plotter and see what it reports for me, but if it's anything like yesterday, I'll easily get a full day out of the battery as I won't be able to use it as much today. I'm going to be working a lot

I have 30 days going to wait and see of it improves or see what others report and then may report
Yeah I'm leaning towards battery life sucks because even when its off it is using up more battery than my evo did.
I can get full charge to last like 4.5 hours with moderate use.
And the display is by far the biggest offender
Right now it is ay 61% it battery use going to display
Juice defender saves your battery like whoa when it's not being used. Here are my current battery stats:
Current battery life: 36%
Time off charger: 9 Hours 30 Mminutes
Display: 57% (screen has been on for 2 Hours 26 Minutes)
Cell Standby: 25%
Phone Idle: 6%
Dungeon Hunter: 4%
Android System: 3%
Media Server 3%
What in the balls is media server?
I consider this phenomenal battery life compared to my EVO when it launched. It will only get better from here
READ THIS:
The way SAMOLED works is that each pixels is individually lit. Because white consists of the most light, viewing anything with a lot of white will kill the battery faster. Black, obviously, uses the LEAST amount of battery life. You can gain a bit of battery life just by using a darker background for your home screens.
Because of this, web browsing is a huge battery killer.
Yeah I've used that program but I'm trying to still be able to use things like gtalk juice defender kills data intermittently making im programs useless
My evo on jd got like 18 hours battery life and without like 7 which would be great for my epic
4 is a bit extreme especially when it goes from 23 to 12 in 1.75 hours with it being off

The APPS section of Juice Defender allows you to select apps that can use Data. When you open these apps, data is enabled immediately. You'll see the 3G logo kick in. It requires some tweaking to make perfect but id definitely worthwhile.
Just remember. White pixels on epic kills battery faster than Evo.

Thanks for the tips friend
...4 hours of heavy usage (wifi connection and 3g on but idle)
Mid to periodical usage could reach 24h.
6th day of usage....
i think this is mediocre for me. please report your battery performance to compare.
Any tips to improve this?
I can get around 8-10 hours with heavy usage... constant music, etc.. and about 2-3 days with light-medium usage.

Hmm so i guess there is a problem with my device.
Great!, and how am i supposed to explain this to the service?
I get about 12 to 15 hours of heavy usage via web, text, and email. If i watch video it's less but I am pretty happy with the battery thus far.

I can only get around 7 hours of use.
I have a problem that if i even dont use it, the battery still drain. I got it full charged and theb unplug it. About 8 hours later, it went down to 50%.
Is there any problem with my device?

same here. i don't know how you guys are getting so much better battery life. i can barely last a day and i don't use it all that much. maybe 2-3 hrs of surfing the web over wifi (not even 3g). i even used setcpu to underclock to 200Mhz when screen is off.
Maybe it has something to do with the very first charge.
When i unboxed the battery was fully charged so i drained it and had it charged for 8 hours. maybe it needed to be charged prior first usage.

Is that 12-15 hours with the screen on? Because that's much more than I'm seeing.
I've done a few measurements just to get an idea of the battery life. They are just extrapolations based on a few hours of runtime for each so they are by no means exact, but my impression is that they give a decent view of real values nonetheless. The battery percentage indicator does not seem to be terribly non-linear.
Video playing (SD quality) with full brightness: 5.5 hours
Video playing (SD quality) with lowest brightness: 9.5 hours
Idle at homescreen with full brightness: 6 hours
Idle at homescreen with half brightness: 9 hours
Idle at homescreen with lowest brightness: 12 hours
Music playing in headphones (screen off): 90 hours
Can't believe how lazy reviewers seem to be, I haven't read a single one where they have properly measured battery life for things like playing movies or reading an ebook. It's all just subjective feelings (which are obviously very unreliable).
All in all I am pretty pleased with the battery life (but I've just had it for a few days). I especially like the fact that it's basically a normal Android phone just with a giant screen and battery. This obviously means that standby and music playing times are going to be excellent.
Edit: Those of you who think you're seeing bad battery life, what does the battery use thingy in settings say? Or is that not a good tool?
I read a post somewhere where the OP was getting horrible battery life and found out that the Gallery app was draining the battery.
The OP in that thread said even exiting the app did not kill it, and it kept draining the battery.
Perhaps you can look into this more. I never use the gallery app so maybe why this is why i get decent battery life?
Edit to add:
Here is the thread
http://forum.xda-developers.com/showthread.php?t=826472&highlight=gallery
If it's this post you're referring to it's by me . The Gallery application shows up under battery use though, so I'm pretty sure that's not it.
Are you sure it's really as much as 12-15 hours with the screen always on? If it were 9-10 hours with brightness at half it would around what I'm seeing I guess, but 12-15 is quite a lot more. Not that I'm disappointed, but if better is possible better is what I want

No not 12-15 hours with the screen always on.... I get 12-15 total... Screen on for usage, off for a while, back on to email and SMS ect...
Ah ok, then there's no discrepancy .
I got 10 hours from full to complete off. I was using it to watch streaming movies on 3g
for a couple of hours and then watch a movie off of the sd card and an episode of supernatural.
After that its just web and ebook reading. Its pretty good. Almost the same as my ipad.
I got a total of around 14 hrs plus with wifi and edge on, screen brightness at 20%, around 7 hrs of standby while i was asleep at night, with 4 hrs of heavy surfing, youtube etc. . . No calls though, only some sms and always on IM with nimbuzz logged in.
What i am seeing is with heavy usage i.e. Multiple apps running, wifi and edge on, i get anywhere between 5-7 hrs of battery life which i think is fair enough for a device this size which am constantly fiddling with.

Using the supplied mains charger, how long does it take to fully re-charge a drained Galaxy Tab?
As it is a large battery what sort of charging times to expect?

I've not used mine for that long, but the Battery Left app(which I found to be quite accurate on my N1) shows that for MY usage, I'll get about 25hrs.
I've got the auto dim turned off, and brightness at max. I mainly use mine for checking emails, txting, and a few games.
Nothing heavy.
I'd recomend the Battery Left app to you guys looking to find out your battery life. You DO have to "train" it though, which requires a 100%-0% run for you.
Guys,
does.anyone know, do we need to cycle the battery to give it the best performance?
Example, charge up the unit, then drain it completely and recharge it again? Like in the old days.
mine hasnt gone down much. I have it unplugged at 6am and at 4pm i still have about 75-80% batt left.
This is with about approx. 2 hrs of talk and 30mins of data usage and voice calls paired to my BT headset. My screen brightness is set to 40%

I once got up to 20 hours of moderate usage. But with heavy usage I get about 12 hours or more. I lose about 7% when watching an episode using flash....kinda sucks but I watch a lot of anime online. But I use this as my main phone too. Its replaced my nexus completely. though it was nice with my nexus cuz I could swap batteries. This is how I condition my battery. I let it get to about 2-5% then I recharge it. I don't let it get to zero cuz I heard you can damage the cell. sometimes I charge it to about 20% then I unplug it and drain it to 5% then back up to full. I just kinda switch it up. At first I was getting horrible battery life but ever since I started conditioning it this way I get great results.

I know it isn't normal.
I swapped batteries two nights ago. I have spare parts installed. My wifi has been on the entire time. GPS was on for 6 hours today when I forgot to turn it off. I work in a basement.
I'm about to go for a walk and listen to music, but I'll be back in an hour. Ask your questions. I don't understand why some of you are having such a hard time with your battery life. I'm not doing anything too weird or even putting my phone in airplane mode.

Its all in how you use your phone. If you turn on wifi and leave it on your desk then I could see 50 hours. Also what rom/kernel are you using and are you using an extended battery?

Normal battery. Running Mammon's Bonsai4All. I've talked on the phone for about an hour total in the last two days. I played games for maybe an hour. I used the gps for a while today, then went back to the basement. Didn't listen to much music before tonight. Bluetooth headphones took it down a bit. A little less use than normal. Usually I swap batteries once a day.
That's not a whole lot of use. I've gotten up to about 35 hrs before on a charge but I used it more thn that.
sorry to thread jack, but is there a tutorial for spare parts for optimal batt life?
I have Bonsai as well but only get around a day at best with minimal use.
Battery is calibrated too

You get about the normal. I think it's actually considered average since about 16 our so hours is what I get too. My guess is that these folks put their phones in a cryostasis chamber to achieve that type of life. However, I believe the op mentioned "replacing" the battery. I wonder if that was a brand new one or what?
I normally get about a day of use, with a bit more use than what got me this much uptime. I have had some new things to work on at work and new games to play at home, so I haven't been on the phone for things as much as usual.
I do have 3 batteries (all standard Samsung batteries), but I randomly get unexpectedly good battery life even with normal use. I think one of my batteries is holding more charge than the other two.
I'm shocked you guys get such good battery life.
I went back to DI18 for a bit after DK28 to see how if battery life was any different. I'm running stock everything, no DRM killers, just the "Samsung Experience" with Launcher Pro.
It's sad and embarrasing. I'm lucky if i can pull 8 hours, unlucky if i stream 4 hours of pandora and its dead. I have 2 batteries and I've gone through both in the same day while at work listening to pandora
I get a full days use: on stock eclair 2.1
I use Mobile ap for like and hour and half
Talk on the phone for like an hour a day
Text like 100 at the most a day
Browse the web on wifi for like 3 hours at home
Using these after the day is over im at like 30 percent.
I'm at 72% right now, 8 hours since unplugged.
Phoenix Kernel and Syndicate ROM regular.
Set CPU 100min, 1200 max
Screen off 100min, 200 max
I JUST plugged in at 1% - after 78 hours and 4 minutes. Some texting, Talk, voice & Gmail. Mostly on Wi-Fi was the key. I still said wow, heh. I just did this (third option) on "stock" DK28:

I do something similar to that third option. I have three batteries and two chargers (one for each battery that isn't in my phone). I charge in the charger until it stops, and then about half the time I pull it out and pop it back in to bump charge it. I make sure to bump charge before I recalibrate. And I recalibrate one of the three batteries every two weeks or so, so they are all done every six weeks.
I've been frustrated with the inconsistency of the battery life on HD2 WP7, when with the same settings you get dramatically different results on different days.
However, I am pleased to announce that I was able to get 4 (FOUR!) full days of battery life on 1 charge from my phone this week. Admittedly, it was on light use, however, during this time the phone was never powered off or connected to a computer. It was mostly on standby (not airplane) mode, with auto backlight on, location on, but wi-fi, data and bluetooth off most of the time.
During these 4 days I did the following things on the phone:
- talked for 1 hour total, using bluetooth st. headset;
- browsed web for 1/2 hour on wi-fi and 3G;
- watched 8-minute YouTube clip;
- with camera: recorded three 2-minute video clips on 720p and took 7 still 5MP pictures with flash off, using SHCameraApp;
- browsed Marketplace for 10 munites, installing 1 app;
- checked emails twice a day;
- played audiobook for total of 40 minutes on speaker and BT st. headset.
Normally I use it more heavily (was getting 2 full days with moderate usage on WM 6.5), but this experiment is encouraging.
I am using Moon Light ROM with 2.15 radio on U.S. T-Mobile, with stock 16 GB class 2 microSD card. I haven't installed any battery-related tweaks. I need to clarify again, that with this ROM and same settings I don't always get same results, and the battery indicator sometimes doesn't show full charge even with green light.
At the start of the experiment, however, the phone was fully charged through USB connection to PC.
wow...4 days is amazing.
ive been saying this for weeks, IF you can get the battery to fully charge its actually fine. almost everyone complaining that it doesnt last very long hasnt fully charged the battery, and i dont blame them for thinking this because everything on the phone is tell you it is charged.
i just used an external charger, got another battery and swap them everytime i run out of juice!
if 4 days is achievable then its ok for everyday use.
i found many people complaining even on native wp 7 phones like htc trophy lasting only a few hours...
so I think its really not HD 2's fault

I agree...my friend has an HTC 7 Trophy and the battery acts roughly the same as on my HD2.
same here, battery life is no different for me on 7 than it was for 6.5, something else to note is that for me it will say it's low for 3 or 4 hours at least before finally running out

Does your HD2 do any random reboots using the 16gb class 2 card, because mines was doing that using xbmod

no point asking questions like that because it doesnt matter what anyone else has, i could buy the exact same card as you have it may work perfectly
no two cards no matter how identical they are, are the same, luck of the draw.

Yes, I had the random reboots problem at first!
But I completely resolved the problem by flashing the 2.15.50.14 radio.

Unfortunately not all phones act the same do they...even between HD2 you get those with long battery and those with short life span. My friend Trophy does run the same as my HD2. You will notice some users get up to 2 days on their HD2...some struggle to get 12 hours...thus battery lifespan varies...i'm getting roughly 8 hours with heavy usage and over 24 hours with light usage on my HD2. Keep in mind that it does vary between users and consider that before posting bull to someone as the battery lifespan does vary a lot at the moment.
Edit:
BTW...what does your Trophy get compared to what my HD2 are giving me. Also I read some peoples HD2 overheats especially while playing games...mine aren't even with playing games a lot on it...maybe I am lucky but I do think somewhere something like SD cards, radio etc does play a role in all of the above.

how about switching to android to do the charging and then switch back to wp7 once fully charged? that way we can find some use for our android ;-)
I have two batteries and one is in separate dock that has battery charging at rear and the other battery is in the phone. I charge the phone all night with normal charger plugged into phone and in the morning at about 7am I unplug from charger and go to work, by 2pm to 3pm the phone is flat. I have email sync, bluetooth, WiFi and location on. I then get home at 5 to 6pm and grab battery out of separate charger that has been charging all day and phone will be nearly flat by 11:30pm 12AM.
I also own a HTC Mozart 7 and with all services running the same as the HD2 and the battery time on the Mozart would be double and it has more use with calls.
Can someone explain the "make sure your battery is fully charged" comment that is in this thread?
Update
Here is an update on my original post #1.
There has been exactly 48 hours since I charged my phone (through USB) at the end of the 4-day experiment. This time, after 2 full days, the battery indicator shows about 2/3 (!) of the charge still left.
To be precise, I didn't do much with it during these 2 days, only listened to audiobook on speaker for 20 minutes, manually checked email few times, downloaded attachments, and did some light web browsing for 10 minutes.
Still, I haven't powered it off, and it's been on automatic backlight, so only 1/3 of battery used in 48 hours is a very encouraging sign.
The phone (and battery) is just under a year old, and I have a habit of not charging the phone until the charge is low, so maybe that's a factor, but after switching to WP7 I was having battery problems like many people describe here.
My battery atm is sitting on 66% and it was last charged just over 12 hours ago. I havent spoken much on it today except for 1 call...sent 7 messages and played 4 turns on Spell It since then...thus light usage.
Strange thing is like some mentioned in threads...at the start the battery ran down quick...about 45% during the 1st evening in 8 hours...when not used. Now its lasting ALOT longer...its as if it settles over time.
in my experience it has to do with your data being off.
XBmod-WP7-V1.04b
radio 2.12
4:30--11:30---7h Data-off 3G-off Bat-75%
00:00--9:00---9h Data-off 3G-on Bat-94%
what i mean by make sure your battery is charge is that windows may not charge your battery fully, but it may report your battery as being full, some simple maths should do, if you have a 1Ah charger your battery should only be full around 1.5 hours later depending on usage whilst charging. now most USb ports only pump out 500mAh so again taking in to acount that your phone will be using some of that power to run its self and your looking at around 3 hours charge time
Now sometimes i find that if i charge my phone and then stick the battery in another HD2 running WM6.5 its only about 60-80% charged, i find that inorder to get a full charge without faffing about i need to use an external charger or use another HD2/ROM. if thats not an option then i find restarting and charging, or unplug and charge usually does the trick

Hi Guys,
How is your battery performance going? We have three 64GB 3G Lenovo tablets in our office and we are struggling to get two hours usage out of any tablet. Even just leaving them in standby mode will drain them fast (less than a day). I have the acer iconia A500 and can leave that around for days and still have some juice when I pick it up again. Any idea why battery life is terrible on the Lenovo? We are all running different apps. Mine is pretty much just running stock with a few ebook reader apps.
Cheers,
SB
Something is wrong with them if the battery life is that poor. Presumably with the hardware if you're running things mostly stock. Strange, though, that it'd be all of them and not just one. Mine gets 8 solid hours of medium to heavy use, no sweat, and other people have indicated theirs get about the same. You might want to contact Lenovo's tech support (though just a word of warning, they have kinda lame tech support nowadays...).
I've got a 32GB no 3G tablet that continues to surprise me with it's battery life. I'd read plenty about folks with crappy recharge and usage times.
Mine will still have the same charge the next day if I don't put it in the dock and I generally get 7-8 hours out of a full charge, even over the period of a few days.
The old 'cell-standby' battery drain disappeared a while back. Don't know why. Don't miss it at all.
Under normal use for me (sketchbook pro, browsing, and an occasional game) I get about 8-12 hours of use (basing that on the screen on %), with 3-4 days between charges. Something is certainly up with yours, what is listed under settings>about tablet>Battery Use?
Info
Tablet 1:
Battery 69%, 7 hours on battery, maybe 20 minutes use. (Mobile broadband turned off)
Screen 39% (on auto brightness)
WiFi 26%
tablet Idle: 23%
Cell Standby 7%
Android OS 7%
The other two are not available, but as a colleague ran out the door, he mentioned that his cell standby was 33% despite mobile broadband being turned off.
Thanks for your feedback so far.
Mine (16GB version) lasts for 4 hours when it's REALLY busy, that means when I stream videos over wireless.
Otherwise...after a full day of normal usage I'm back from 100% to 40%.
Anything else I think is not acceptable..I suggest you guys have your tablets replaced.
Wait, I just had a thought. Are you guys using the keyboard folio with the tablets? If so, there's something you should know. After putting the tablet to sleep, you can't close the folio for another 10-20 seconds afterwards. Otherwise, the optical trackpoint ends up detecting motion from the tablet being on top of it and it wakes the tablet up repeatedly while the thing is sitting closed. So you have to put the tablet in sleep with the folio still open, let it sit until it goes into deep sleep, wave your finger over the trackpoint to make sure it has (after 10-20 seconds), THEN close it up.
my battery is good on standby (with wifi sleep).
Your battery drain is because of cell network. use airplane mode !
I RMA's 2 of them with the same symptoms, took all day to charge, discharged way to fast they ended up having both bad motherboards and bad batteries. I called up lenovo sent them in and had to wait about 3 weeks for the parts to come in, but they have been working incredibly well now.

That sounds very similar to the three we have. 6-8 hours to charge. Less than an hour of use to discharge. Less than 10 hours on standby to discharge. Lenovo suggested a factory reset (ha ha) to fix the problem. I'll humour them for the weekend.
