As you all know the o2/MWg Atom Life has an extremely short battery life with the original battery and i'm curious as to what you guys would recommend to preserve the battery life on the Atom Life. Heres a list of what i've done so far if you want to make the most of your battery life:
1. Change the battery to the XP-02 instead of the standard 1530mAh battery which comes standard.
2. Change the CPU Profile to 'Best Power' (Settings>System>CPU Profile)
3. Flash the ROM with one of MedKid's WM6.1 ROMs (advanced..sorta)
4. Reduce the intensity of the Backlight (Settings>System>Backlight)
Any others?
GSM - 3G
I haved tried all the methods as recommended can help but to a very limited extent indeed. I found out the best tip from MWG O2 website: if you don't need to use 3G band switch, change it to GSM, (go to Settings - Connections - Band Switch). the default value is Auto.
After that, the battery life of my Atom life increases significantly from less than a day to more than 2 days!

I just changed my band. Let's see if it helps me. Would report when my battery goes low.

there are various GSM in my phone: GSM900, GSM1800, GSM1900, (GSM900,GSM1800), and (GSM900,GSM1900). what do i choose?
thanks
Leave it as "Any" the default value

I'm using the XP-09 at the moment until my XP-02 comes in and the only problems i've had are an extremely low battery life and occasionally the battery life will hit 0% after a full recharge with a third party charger i bought.... and dont use anymore.
PS: I'm gonna try the band switching thing, lets hope it helps! XD
My phone came with a XP-02 in India. I complain about low battery life. Can anyone post the standby time of both batteries?

My O2 Atom Life phone came with XP-09 in a pretty-pack box from company in INDIA.
The battery lasts around 2 days without any problem with talktime aroung 1 hours in two days. Standby time is more than 2 days for sure with no calls made.
If you watch videos or audio or FM Radio, it lasts around a day or even less if too longer the video is watched.
Just changed to Band Switching to GSM and lets see how much difference in battery life I get, will post later.
Mine came with XP-02. And it lasts for max 1.5 days without making much phone calls. Anyways would try with XP-09 now.
my atom life use cpu profile normaly. max 6-7days(24hour) standby no call,no sms.. only received sms. hmm..
cpu profile?
hi hendranata, do you mind sharing this cpu profile? i'm using a wm6 cooked rom on my atom(not atom life/flame)and i saw a cpu profiler in the ext rom. i'm not sure if this the same but nothing happens if i run it i've read in so many threads and forums that the default atom battery is major complain of everybody, this might improve it, the batterry performance i mean. tia.

I've had my mwg atom life a week and it came with 1530mAh XP-09. So far, I'm very disappointed with battery life (1 day at best) and I'm looking into getting a replacement battery. Is it possible that I have a faulty battery or is this typical performance?
I've seen various sorts on ebay ranging from XP-02 1500mAh (which is presumably going to be marginally worse than my XP-09) to a 2400mAh which seems to be thicker and comes with a new cover to accomodate it - but then it's not going to fit in my case. I haven't seen a 3000mAh as mentioned in this forum. Do the replacement 1500 ish ones perform better? Obviously they shouldn't but some people's comments here seem to indicate that maybe they do...
Which batteries are other people using and are they standard size?

hm.. u use atom life for what? call? sms? gaming? internet?
a little of bit of everything really. I realise that if I'm using a lot of bluetooth, wlan or watching videos etc then battery life is going to be short but I'd say a day maz just on standby with nothing more than a couple of calls and texts ie light normal usage. I;m getting a bit fed up with it tbh. Today it's refusing to make calls for some reason...

i personally think that ther's nothing wrong with ur battery.
o2 atom life is reknowned for their battery issue.
by following the few instructions given in the 1st post, you can slightly optimize your battery life. but dont have high hopes.
a daily charge is required normally.
i had times wher i onli need to charge it after 2 days of usage.
Battery drain
Hi
I had the same problem with the baterry, so I changed this:
1.- CPU Profile to "Best Power"
2.- Backlight reduce to 1
3.- Disable 3G if you don't use and change to GMS "Auto"
4.- If you use SPB Shell like me "THIS IS THE BIG PROBLEM" for default SPB consume a lot battery so you need disable the ANIMATE option into setting SPB Shell.
Before do this the battery in only 12hr are consumed all power, now in only 24hrs the battery are consumed 16% power battery without reload the battery. amazing no?
Hey, after using my new 1530mAh battery i bought from ebay i found that it lasts maybe a month with the occasional check of the screen and messages. When i play music(that's pretty much what my phone is for..) it'll last about 16 hours before running out.
I'm using:
1.One of the latest PDAViet ROMs
2.using the AUTO CPU profile(i know its a terrible idea)
3. backlight at 5
4. Radio at GSM900 (not auto)
5. WLAN and Bluetooth almost always off.
PS: buying the new battery was a GREAT idea for my case.
How does the battery behaves when compared with HTC HD and the original Diamond?
I found a good review article of the diamond2
"In terms of battery life the Diamond2 promises nearly double the amount of standby time over its predecessor. From my time using the Diamond2, starting with a full charge and with frequent use (web browsing/ music/ camera/ the excellent bubble burst game!), the next time the phone needed charging was five days later and even then this was more of a top up rather than the battery running on empty."
(http://www.mobiles.co.uk/htc-touch-diamond2-review.html)
i cant quite beleive a 5 day battery life on this phone! if it is true then it will be awesome but it has a smaller battery 1100 mah against 1350 in my phone currently which i get about 1.5 days out of it.
So i will be reserved, and slightly pessimistic

I would expect it to perform like your current phone (the HD, right?). smaller battery but smaller screen, so it should be about the same, and the htc provided data seems to be in line with that (about the same stand by, talk time and video talk time...)
So I think u are right to be pessimistic, but I also think that a higher capacity battery is possible with the same size as the 1100 mAh one: This TD2 battery is large, compared to the TD1 one: about 2 times as large, and TD1 was 900 mAh. Except if they are not of the same thickness, TD2 battery should have a higher capacity than just 1100 mAh...
I found nice shots comparing internals of TD1 and TD2, where we can see the 2 batteries
http://www.mobile01.com/newsdetail.php?id=7317
I do not know how TD2 battery compare size-wise to the HD, maybe you could post some pics of your battery? side by side shots of TD2, TD1 and HD batteries would be very nice, especial it we also have thickness shots anyone having acces to the 3 care to post those?
gkai, no i dont have an hd, i wish i had one. I only have a polaris which is why i cannot understand the 5 day battery life as if my current phone does not last that long. I think that something that is more powerful, bigger screen and a smaller battery will last as long, i just dont, and also mine is stated to have a 400 hr standby time and the td2 only has 360 hours.
So i will still be pessimistic and say that they had some wonderous phone to get it to last for 5 days! (or didnt touch it for about 3 days!)
also the physical size of the battery does not actually matter the rating of the battery is what matters and that is smaller therefore a smaller battery. The td1 i think was always said to have a really bad battery life so hopefully htc have heard this and made the td2 better with a longer battery life, we can all live in hope

hum, then it is possible: faster processor does not mean that it will drain battery faster: new generation are etched finer and use less power for same or more processing power. Screen can be (slightly) more efficient, and power saving of the different radio can be better too. But I expect the phone to be good for 1.5/2.5 days of typical usage, no more, given the current behavior of the HD, touch pro and touch diamond (which have almost exactly the same internal components)
So i will still be pessimistic and say that they had some wonderous phone to get it to last for 5 days! (or didnt touch it for about 3 days!)

The second is more likely, I doubt htc has changed the battery for the review (although it is possible). Good cell coverage is also good for battery life, if u have a cell tower nearby your phone will get better standby and communication time, same for wifi. I guess they both were in ideal condition and used the phone lightly...
also the physical size of the battery does not actually matter the rating of the battery is what matters and that is smaller therefore a smaller battery.

hum, yes, it is the rating that count...but given that all good batteries use the same technology (lithium-polymer), mAh rating should be in direct relation with physical size: a large battery with small rating just means that your battery is of an older generation (unlikely), or that there is a lot of dead material (plastic packaging) in your battery. So either the TD2 battery is much thinner than TD1, or it is likely that higher capacity batteries with the same physical size will surface quite soon on the accessory market (I hope for the second case, battery life under normal usage is one of the most important factor for me, it is convenient to have more than 1 day of "heavy" use per charge, and less than one day under "normal" use means the phone is poor for me, whatever its other qualities...)
Bettery Life!
Hi Guys.. Wel 4 days in, and still on my first full charge!
According to the power screen, I have used
58 hours 25 minutes standby
Talktime 2 hours 22 minutes
device usage 3 hours 24 minutes
And stil have 4 bars left!
how to say i think that htc have finally sorted out battery problems and have made a phone with a good battery life. Seems like ive been told!

yes, my mistake However, my point stand: battery capacity should be directly linked to its physical size and weight, given that the technology and materials used are the same (especially if you compare the batteries of a single manufacturer, like HTC). If not, it mean that the battery is not optimal and that a higher capacity battery battery of the same size is likely to come afterwards (from htc or other suppliers). That's why I was interested in the physical size of the TD2 battery compared to other devices...Well, with some luck I will know today, maybe a batch will arrive this afternoon in my favorite mobile shop and I will pick one ;-)
After the first full charge and unplugging in the morning, mine lasted until the evening.
about the same as my D1.
I don't have bluetooth or wifi on ever.
So to be honest, with average use....it's still ****
Good job i bought myself a AA battery emergency charger for it as well
Extend batterylife
Maybe not what we're looking for , but it's a way to extend batterylife:
Just underclock your TD2 or other HTC-device:
Look here and here...
FYI: Overclocking is not possible (yet )!
@Juggles
Didn't expect to see you here, how's life? How's WmGurus?
So you have move to TD2.
How's it?
Good buy?
It's selling here from today in shops between SGD538 to SGD668. Maybe its a promo price.

How you've managed to achieve this I'd like to know. As currently I have 2 bars remaining and I have the following listed:
19 hours 1 minute standby
Talk time 0 hours 2 minutes
Device Usage: 3 hours 25 minutes
since my last charge at 23:25pm Yesterday. It's now 21:53. I have had WiFi and 3G on most of the day mind you!
7 DAYS on Standby within 1 full charge! (however without Sim Card in)
Anyone having battery problems? My wife and I have pros and can hardley get half a day out of it... does this phone need a task killer? I havent used a task killer since my hero. But maybe this one needs one. any ideas? my fascinate holds a charge more than this and it does 10 times the amount in the backround and the batterys arent that different. Thanks
Pretty disappointed with the battery life too. Barely make it to the afternoon. I just constantly plug the phone in. Considering buying the extended batt if it wasn't 50 bucks.
I also switched from the fascinate.

who has the extendted battery
My battery life is OK, but I'm constantly fiddling with the phone: checking facebook, answering work emails, browsing the web and the Market, etc.
However, my partner's phone made it through a 16-hour day with 40% still left of battery. Granted, it was on standby for 6 hours at work, but the rest of the time was constant facebook, etc.
There are a number of "Power Management" tweaks that can be performed that will dramatically improve battery life. Things i have done include:
device rooted via z4root (this has no direct impact on battery performance but necessary for things that do...)
Screebl Pro
SetCPU (throttle down to 300 when screen off)
AutoKiller Memory Optimizer
Uninstalled or frozen a bunch of stuff i don't use via Titanium Backup (there is thread in this forum that discusses what can be uninstalled/frozen)
Changed phone radio from global to cdma
I have also added an extended battery. I can easily go 12+ hours with heavy data/email and voice use.

these are all great ideas. however, most of the reviews are bad on the Screebl Pro and all of its other versions.
I just received mine yesterday. Gave it a full charge last night. Now, at not even 11am, it's down to 60%. That's after three hours of light usage. Hopefully this is just a battery calibration issue or something since this is the first time it's been fully charged...
Edit: 10%. That's 90% depletion in just five and a half hours. We'll see if it's lying or not.
Edit: The Droid Pro was pronounced dead at 1:48pm, exactly 6 hours of very light usage after its first full charge. We'll see what happens on its second cycle.
Hi All
I have to say my battery is great. Can make it the entire day even with heavy usage.
However, you need to be really careful with the background apps you are running.
In my case
1) Bluetooth off
2) Wireless Off
3) Set CPU running - scaled to 300 when screen off and scaled to 300-600 when battery hits 50%
4) Running IMO messenger at boot (I tried Ebuddy and it sucked down the battery big time) IMO does not.
5) Cleared most of the default widgets and only added the few that I really use.
6) Running Go Launcher instead of default launcher (not sure if this helps battery or not)
7) Running CDMA mode only when I am in the U.S. (turned off global setting)
8) I get LOTS of emails daily (over 150) so the phone is constantly pulling in.
Hope this emails helps others.
When I first got my Pro a few weeks ago I was ready to send it back due to poor battery life. Decided to give it a little more time, and the stock battery was netting me at least 12 hours of moderate to heavy usage. Ordered the extended battery and had the same issue of it draining the battery insanely fast. Again, I gave it a few more days and now I'm finding myself charging the phone maybe once every two days. All in all, just give it some time -- it'll surely get better, just hang in there!
Day two: Seven hours in, and my phone is down to 20%. Better than yesterday (dead in 6 hours), but then again I used it much less today, and I removed all but 1 widget from my desktop.
Edit: Dead at 4:20. 7.5hrs today. This is garbage.

Try and hold out for a week. My Dream and Milestone took about a week before they were useful. If its not useful after that then you might have to trade it in or get a different type of phone.
Android is not known for its great battery management but you should be able to make at least a typical 8 hour work day imo.
I've stated in many threads in many forums now, the battery life with the "Out of the box" setup is just horrible. No way around it, it just sucks. The stock battery is the same one that came with the original Droid last year. The Droid 1 is a 600 Mhz stock phone. Our Pro is a 1 GHz beast. The stock battery in our phone is just inadequate.
I wouldn't be surprised to see an update in the near future to resolve some of the issues we are seeing though. It's obviously the biggest complaint with the phone. However if you are willing to root you can get the phone to somewhat reasonable battery life.
I've really only done a few things but am seeing a vast improvement. Stock settings with my usage gives me about 4 hours then I'm dead in the water. Now I get about 7 hours and I'm literally doing something on my phone all the time so I'm completely pleased with that.
My main things:
Root and remove the bloat. Play with the phone a couple of days, find out what apps you'll never use then get rid of them.
Get a different launcher, either Launder Pro or ADW.
Buy SetCPU and set profiles for:
Screen off = 300 MHz
Battery < 70% = 800 MHz
Battery < 50% = 600 MHZ
Change wireless mode from Global
That's it for me. If I used my phone like a normal productive Human I could get a full day easy, but again its literally always in my hands, so 7 hours I am very pleased with. That's about as long as my old Curve got me. After that I just slap my spare battery I always have in my back pocket in and I'm good to go with only 2 minutes downtime, as opposed to the 15 minutes down with any Blackberry battery swap.
That's my 2 cents, take it for what its worth. My biggest battery gains came from SetCPU, and to be honest I really can't tell a difference in performance when it throttles me down.

Which extended battery? Do you need a new battery cover?
This guy is selling his Droid Pro for $500 with extended battery.
http://cgi.ebay.com/Motorola-DROID-...0741502439?pt=Cell_Phones&hash=item3a615bb1e7
The battery life on this device is very low. I ordered my extended battery here on eBay: http://cgi.ebay.ca/ws/eBayISAPI.dll?ViewItem&item=150532539861
I like that is has an original backing and there is no noticeable bulge.
Verizon is selling extended battery for $50+tax with free overnight shipping.
I got lucky. The seller has since revised his listing to NOT ship outside the united states. Its a shame for all those who've purchased their phone for use outside of the usa.
Well I have to contradict my last post. I burned through 2 1/2 standard batteries Sunday during a 16 hour day at work. I decided to break down and purchase the extended battery.
I bought it yesterday and threw it in my phone last night before I put it on the charger for the evening. Today I'm very surprised to see I'm still sitting at 40% with the phone being off the charger since 8am this morning (10:46pm now.) So 12.75 hours on just the extended battery, I'm thrilled. I would almost say this battery would net me more time than 2 fully charged standard batteries.
I bought the Shell/Holster combo at VZW when I bought the phone. I could not get the shell to fit over the extended battery back without modification (as I've read elsewhere). However, I threw the shell in my oven for about 10 minutes at 200, and the plastic was pliable enough to wrap the phone. It then cooled down and now fits great. A little snug, but it functions perfectly (actually fits better in the holster IMO). I would highly recommend the extended battery. I can see why everyone is saying great things about it now..
The salesman at the VZW store got me 25% off for something (Forgot exactly why I got the discount) and they had one in stock. So I would definitely encourage those to go to the store 1st before buying online. (The salesman, who was a manager, said the only reason they had them in stock was because their store has sold so many of the Pro's).
the has gotten better since we got em but i thing i found which seems kind of weird is im getting better battery life with my screen brightness all the up and my battery manager set to performance
I just got my extended battery in the mail yesterday. I am noticing a huge improvement in battery life with the droid pro. The annoying thing is the back for some reason does not "snap" into place properly. Not too sure why, but putting a piece of folded paper underneath the cover seems to have done the trick.
To anyone seeking to further extend their battery life I recommend getting the extended battery from verizon. If that is still not enough you can buy the Energizer USB rechargeable battery and go from there...
So we all know that low numbers in current widget are good and high numbers are bad. Thing is, how do we interpret these numbers? I mean if my phone (HD2) is currently drawing 4ma how long should I expect it to last/how much percentage of the battery should it drop an hour?
What about when it's drawing 189?
How do you do the math to figure battery life out?
Its just been puzzling me...

Your battery is 1200mah, that's milliampere hour. So if you're drain 4ma, then it'll run at that rate for 1200mah/4ma = 300 hours. Same for your other numbers.
If only it would run at that rate consistently hey .

Its actually 1230mah
the important thing is that it shoud have the minimal drain at standby moments ... becouse when using the device ... it gets as high as 450 ... on top spikes usualy 200 - 350 so dome nice man should think about minimizing the spikes when used.
By the way my girlfrind just bought a wildfire ...stock and it gets like in stand by 25 - 50 ma and when using 200-300.
Mine with nand android gets like 2 - 5 ma with some little spikes at 30 sometimes.
pretty cool
Indeed it is ! i have both a desire and a hd2, i used the desire for months while waiting for magldr, that things never idled below 20ma to 40ma and with the screen on was usually 350ma to 400ma
now the HD2 with a bigger screen uses less, like 150ma to 250ma and sleeps on under 5ma lol !
the desire may have more battery (1400mah batt vs hd2 batt 1230mah) but it lasts allot longer thx to more efficient use.
One question from a noop.
If i enable bluetooth over different builds the battery drain is quit different.
With most of the HTC builds, like Desire HD i get a battery drain between 3 and 5 ma in standby. With Stock builds or CM builds i get 60 ma in standby?
Has anybody the same experiences or can explain this?
Best regards

same issue for me but i dont know why this happens

I had this with early HD builds too - I think it may be that it's not going into low power standby mode (just enough to keep connection active)?
Try wifi too - that should settle to 5/10ma if idle.
@ T.S.: You should try the Battery E.T.A. app: http://www.appbrain.com/app/battery-e-t-a/com.ac19.beta
This app shows you the current battery percentage + it displays a calculated "end of battery" time, based on your usage of the phone over the last day/2days/..

That happened to me too with DHD builds and i've tried many things.. the solution to stop the heavy battery damage (sometimes) was just opening wifi and go Idle
So let me get this straight: it is normal for my device to have 400 mA when using it?
Anyone think it's possible to get those "top" ma's down? Because it's draining like 350 ma in full use.. would be cool if we get it below 200 or something Maybe with something like those ultra low voltage builds that you had on the sd android version?

use setcpu and limit to like 400 mhz. it will be sluggish but u get your 200ma. also turn off backlight. but there's no point doing that.
Haha oke I get the 400 mhz.. but thats not what I was looking for

HD2 is the best Android phone on the market. Nothing compares to it besides the Evo and the build quality on those isn't as good as the HD2.
I've ran some tests before. With the phone idle and the screen at the dimmest setting, it drains about 100ma. Turn that up to full brightness and it goes up to 230ma. Phone calls have the screen off and it uses about 150ma or so. The rest is just how hard the phone have to work.
It's really not bad when you think about how much it does out of that little 1230ma battery. You can get close to 7 hours of talk or browsing at dim light. 12 hours of music playback, 250 hours of standby time. These are pretty good numbers. If you really need more than that in one day, you just need one of those extended batteries. I hear this one works pretty well in android without custom kernel

I think I've finally gotten a good grip on this Nook stuff, a million thanks to everyone here.
My Nook is where I want it to be currently with the latest CM7 stable.
It seems like everyone is overclocking and now I'm curious.
Do you guys keep the overclock on the entire time you're using the nook? Or do you turn it on when you need the extra performance?
Does it shorten the battery life by much?
Is it harmful at all to the hardware?

Good questions. Overclocking is, on the surpface, something one would imagine harms our toys. Actually, most can handle well. It's all about the voltage and not so much anything else. Dal and others have worked out the tough stuff and provided us with some extremely useful kernals that noticably increase speeds (demonstrable with apps like Quadrant Standard or Smartbench) Apps run quicker and the overall experience is sweeter. Ondemand is the usual govenor I employ set on boot. (Running CM7.0.2 1.1 OC) Still getting a full day of use before recharging.
Usually it only kicks up to overclocked speeds when it needs it, cm7 can regulate it's clock speed pretty well depending on what setting you use.
technically overclocking will slightly shorten the life of the processor (uses more power, produces more heat). It doesn't really matter though as my battery will give out long before my processor, regardless of whether i overclock or not.
By that time i'll probably be thinking about buying the sweet new nook color 4 anyhow.
I have one of the handfull of Nook's that can run at 1.3 GHz, although I have it set to boot at 1.2 GHz to eliminate the occasional bootloop from trying to load up at max speed. Once booted I kick it back up to 1.3 GHz and leave it. My battery generally lasts 48 hours of light / moderate use with the display being the single biggest power hog.
48 hours of using seems impossible to me when I use my NOOK at work for FB and some little gaming (not 3D) and after 8 hours is at 50% of battery.
I use daily 300/1300 at On Demand and never had any problems with device.
Extra heat is harmful.So if the device isnt get so hot, then things are ok.

You're right 48 hours of use is impossible. To clarify.... I'm usually off the charger for about 48 hours... not 48 hours of use. I'm 20 hours off charger now, wifi running about 10 hours, screen on for 2 hours 24 minutes and battery at 53%.

When does the battery meter reset? Is it when you charge the battery back up to 100%?
I just got CM7 working and haven't had a chance to go through the entire battery yet but based on what I've seen so far I can maybe squeeze out 5-6 continuous hours of usage, does that sound reasonable?
Based on what I see it's significantly hungrier than the stock.

Depending always on what U do during usage (different to play games or just browsing the internet), U should really have the hours U propose.
Soon the problem with the sleep will be solved and the autonomy will be back to normal.
