Rather than clogging up other threads with my battery experiences, I thought I'd summarise where I'm at, and see how other people are doing with their battery life.
So I started yesterday on a full charge, and by 2ish the phone was dead. I used it fairly heavily, but wifi was off. I don't think I made any phone calls, and didn't use gps. It was mainly messaging and using the xda app. I had changed my screen brightness to auto the night before, so thought this might have reduced the battery life.
I then left the phone off, and charged through till just before 5pm. At this stage, the phone was up to between 90-100% charge. My intention was to see if I could get through to this afternoon on this charge. Last night I made a phone call for about half an hour, and used gps for about 10 mins driving in the car. Other than that it was a bit of messaging and browsing, but not heavy use by any stretch of the imagination. I had wifi off, facebook sync every 4 hours, and screen brightness set to about 50%.
This morning I woke to less than 10% charge on the battery, so have left the phone at home charging, and I'm back to my hero...at least for the morning.
I must admit, I'm starting to get concerned, because I really don't think I'm using this phone more than my Hero, and I could easily get a day out of it (unless I was going for a long run using some kind of gps app).
What are other people's experiences? I'm surprised I'm not hearing more about this, and I'm hoping mine is just a one off!
**UPDATE**
Today, 12 hours after taking my phone off charge, I have just under 20% charge remaining. The phone is now on it's fourth cycle, and although I haven't used the phone quite as heavily as yesterday, I have still used it quite a bit and have had WiFi on the whole time. This is still not amazing battery life, but it is still much improved. It definitely illustrates that the battery may take a few charge cycles before it optimises itself.
My first full day was yesterday.
WiFi on all the time. Screen brightness set to automatic. Twitter and facebook refreshing every hour. Weather every 4 hours.
Unplugged the phone at 7am, 100% charge.
During the morning I flashed the phone twice (due to the proximity sensor issue) so it probably recieved an extra 10 mins of charge.
Following the flashing, WiFi went straight back on so I could download all the apps again, and resync sense and all the contacts. There was some playing of games, some use of Google Goggles (so camera use there) and some web browsing.
By 13:00 I was down to 90% battery - which was pretty good I thought.
Through the afternoon I didn't get to use the phone much apart from a couple of short gaming sessions.
By 17:00 I was down to 80%. I got home from work and played around on the phone until my wife got home and we went out for a meal. The pub we were in had no signal, and I didn't really play around with the phone.
By the time I got home and went to bed, the phone was probably around 65% full.
So not a heavy day of use, but not far off a standard day for me - so not too bad as far as I'm concerned. Certainly about 30% better than my Touch Pro2 was!
I think we need to define a consistent way to measure battery life for Android.
Something like ACID test for web ... Quadrant for benchmark ...
I don't know, maybe we can agreed on something how to measure it. Or build an app to simulate phone usage which user should run it continuosly and then at the end got the result: Your battery life is rated 4 hours, 10 minutes straight using this test.
Probably not the best measurement, but it should give us a "number" to compare with other devices.
I can only suggest (I am not a developer), but I believe there are a lot of talented coders here in XDA which should be able to build this kind of "standard" app battery measurement pretty easily.
Somebody is recommending 3-4 full charges cycles for battery optimization. Do you think it will really help?
Battery is really deal breaking issue for me.
very helpful thread.
as mentioned few post earlier, there really should be a battery benchmark tool.
so was your wifi and/or 3g turned on the whole day?

My friends also lasted over a day with pretty good use, there seems to be better results with the brightness on auto...from what I have picked up on the forum...maybe a test is need to see how much difference there is between full brightness on one battery charge and auto on the other.
Yupe, the battery benchmark should not be so complicated.
Start the app with 100% Battery life
Some options in the app (for features that might NOT be in an Android phone or might not be available at the time?):
[ ] Turn on Wifi
[ ] Turn on GPS
[ ] Turn on Bluetooth
Set the app to WAKE all the time, display turned ON all the time of the test
Set Keyguard to OFF (device will not be locked)
Set Brightness to AUTO
Set all speakers to SILENT
Set vibration to OFF
Then loop until battery down to 5%, perform the below tasks in sequence:
* Play movie for 15 minutes [speaker muted]
* Browse to website??? be careful not to overload the website
* Doing arithmatic
* Doing 3D
* Play MP3 [speaker muted of course]
As soon as the battery down to 5%, app stop and display result ...
And of course restore all the settings.
The app should use generic API that is supported by Android, not some hacky wacky if you know what I meant.
Please if someone can code this, that would be very nice! Standard XDA Battery Measurement app for Android!

the app should log the result too.. since some phone is dead by time 5% due to calibration..
@Dazultra2000: I would almost trade the proximity sensor problem for the battery life you're getting!
In any case, I'm gonna leave my phone charging till half an hour after the green light comes on, then I'm gonna try another day of normal usage. I'm going to turn wifi back on, as I usually would, and set screen brightness to auto.
With my Hero I used to go for runs using a GPS app to log the route, I'm not going to bother trying that with this phone until I'm sure I can survive a day.

I don't know when you wake up but that could be like 14 - 15 hours that you mentioned which possibly isn't all that bad (plus the extra 10% you had remaining). Personally I want to see what it's like when you unplug it at 8am, not at 5pm the night before since I can't see any good reason not to leave the phone charging over night anyway.
If you then manage to get about 10 to 12 hours or so then there probably isn't much issue. Granted you weren't using it while asleep so the battery shouldn't drain overly quick but I wouldn't want to use your test as an example of a days use.
Thanks for the info but. If I was you I'd just have a car charger too if you like to use GPS...I can't see any reason not to.

Yeah, I would normally charge overnight, but since I had given a charge through to 5pm I wanted to see how it lasted....see if I could get through 24 hours. I wake up at 5am, so that was around 12 hours, with only 5-6 of those hours being time when I would've actually been using the phone. This is also bearing in mind that I had started yesterday on a full charge and the phone was dead by 2pm.
The GPS thing in the car was only to do a quick test, literally 10 mins. I need to buy a new car charger with micro USB, but I just made a note that I had done this because I knew it would affect the battery.
Anyway, we'll see what today brings.

Looking forward to it.
And yeah, for me personally a "days" charge really only needs to equate to about 12 - 14 hours. Thats probably the longest I'll go without having a charge anyway unless I'm camping or something in which case I'll likely fall back to a Nokia anyway.
Hi, just to add my experience with a complete different phone e.g. iPhone 3GS (developing apps on it, now switching to Android ):
Charge at night till 8 a.m. so 100% then usually in a day:
- Go to office, read/write emails, surf a bit on forums, blogs and so on
- Make call up to 30-60 minutes per day
- Play some games, test our application/games on it (so connect and receive some extra charge)
- Use WiFi at office
- Use Google Maps up to 15 minutes per day
- Back at home at 8 p.m.
- Use again emails and surf on web for 30 minutes
Around 11-12 p.m. it has less than 25% of battery, so 14-15 hours of usage drain battery up to finish it, not to mention that I'm forced to switch off push notification because they drain my battery in 5 hours!!!!
So just to say that, no one is perfect, and this devices today really do a lot of stuff, I think as Smigit suggest 12-14 hours are acceptable.
Have also tested/used iPhone 4, I don't seen any big improvements on that side.
Just my two cents...
praying for decent battery, please please please!
My HTC legend is pretty poor really, but I can live with it. If DHD is worse I don't think I can pull the trigger.
There is a thread in th Legend section about 1800mh HTC batteries (from another phone) that fit the Legend. Maybe there will be an option to do something similar with DHD.
I would pay £50 more for a 1500mh battery - why did they put the smallest battery in the largest screen?

No the battery doesnt fit with the Desire HD, if you watch some pictures of your 1800mah battery and than go and take a closer look at the DHD's battery, you will recognize that the pins of the DHD-battery are on its side. the pins from the Incredible Battery are on the bottom.
In 2 hours 30 min heavy heavy heavy use, the battery dropped 20%.
Will do a full day test 2 morrow.

Can any of you dudes that have the phone comment on your experiences with battery life? I'd imagine it would be pretty decent because of the smaller display size and lower cpu frequency, but I've read some reviews that it's mediocre.
Anyone have it last longer than a day on a full charge?
the battery life is better than the backflip I can say that much, but I dont think it will make it 12 hours without being recharged. I actually dont use the voice services that much either.
I would like it even more if the battery at least lasted thru the day.
MY BIGGEST COMPLAINT... the speaker on this phone SUCKS!!!!!!!!! it's a shame, I really REALLY love this phone.

Man, not even 12 hours? I'd hate to see what the battery life on an Evo 4g is like. Is it just because of the 1200mAh battery or is this something inherent to Android?
6 hrs 57 mins talk time. frm real world testing.
i read a review on pcmag web page and the reviewer test the battery life and said it got 7 hours talk time. in real world testing. so its as good as smart phones get. better than a iphone or any other android phone thats out.
Batter Life is GOOD!
Ok....I am new to the android universe as the Aria is my first android phone. However in response to batter life it is really good. I have a friend who has the EVO can can only go about 5 - 6 hours before charging.
I turned the screen brightness on my Aria down to about 30% and I yesterday I went through an entire day of work (messing with the phone a lil) then went home and messed with it for a good amount of time (1 1/2 hrs). When i went to charge it that night it had 35% battery life left.
Today I left at 7:30 am and it is now 3:30 pm and the batter says it is full. Now this isn't a percentage app or anything but the batter on the phone says full. Granted i only have 2G where I live (Edge) and I am not using wifi or anything, plus i haven't messed around with the phone too much today, but that is pretty darn good if you ask me.
Here's what I used mine for yesterday:
Off charger at 7a.m.
During day I estimate that I used:
20 min voice, 25 or so sms, several trips and comments on Engadget, a dozen or more FB app uses, downloaded 2 entire songs via 3G, 15 min of browsing. Multiple email accts, fb and twitter accts syncing throughout the day.
When I left work at 6p.m. I was at 47% according to battery app. After some app downloads and a little surfing, 25 min of voice calls later it was at 25% when I went to bed at Midnight.
It's better than my Pre Plus and better than the Backflip for sure. I'd say that if you're a heavy user you may want a car charger and/or an extra wall charger to be on the safe side. I'd say that for any modern Smartphone though. I'm very happy with it, myself.

My experience is near identical to this.
As for today it left the charger at 9AM, only 10 or so texts today, on standby the rest of the time and it still says 100%
Hmm.. I guess it's highly dependent on how you use your device and how often you have it sync with online services.
yeah, i find it hard to believe some of these numbers. I don't use my phone much for voice. I dont use wifi or bluetooth, i will trigger the gps, and maybe my screen is too bright, I do about 20-30 text messages and yes, some downloading. I get a pretty good signal where I live so I dont think my battery is being eaten up by the radio searching and trying to connect to towers. I'm serious, if I get 7 hours out of this thing I would be super pleased.
I used to this though, I have had many smartphones over the year.. i just need to purchase all new accessories to keep the device charged as much as possible. ( additional charger, car charger..)
The battery life is not as good as my tilt2..but blows the backflip (i owned for about 3 weeks) in the water.
I think the battery life is just as good or moderately better than most smart phones. Vs the 3Gs I think it's slightly better, Vs the backflip I had for a week, it's way better IMO.
Just placed an order. Hey as long as it's better than my G1. I'm happier than a pig in mud! G1 is the worst when it comes to battery life.
Battery seems to be good. I charge my phone at work while it is on. I'm running pandora constantly at work as well. Yesturday i left work and was playing with the phone from around 6-11, using wifi, 3g, bluetooth, some gps, screen on the whole time, multiple apps open, downloaded a lot of stuff, syncing on for weather, gmail, contacts, news, facebook, and a whole bunch of other stuff. That brought the battery from 100% to 24%. I then killed all tasks that weren't needed, turned off all radios except phone and 3g, and let it sit overnight. It only dropped to 23% by 6:30am.
It seems to do really well with normal use. With heavy use the battry falls, just like any smartphone.
my battery lasted all day yesterday with what i would consider pretty heavy usage. i'm very pleased with the battery so far.
I've has mine since SUnday- now wednesday and the battery is HORRID for me.
I pull it off the charger @ 6am, and now its 12 noon and i have 40% left. I don't get on Facebook much til after 4pm, Use iMobsters sporadically for short amts of time, MAY browse the web if a page is blocked @ work, but that's it. Dont talk on it here @ work.
I dont get it!! I changed my screen brightness???

are you using a bunch of widgets on your home screens?
Mine came off of charger at about 7am and it's now at 72% at 9pm. I didn't use it much today as I was busy at work, but it's still checks my email, fb and twitter throughout the day. I do have the Friendstream widget up as well. Overall I'm good with the battery on mine.
My brightness is set right in the middle with auto brightness turned off.
battery life is pretty descent coming from an HTC Tilt 2. especially with 3g constantly on. i pretty much got similar battery life as the Tilt 2 (without 3g on..3g ate through the battery like a cop with a doughnut). i'd estimate you could probably last 18-20hrs if there was some way to turn 3g off...that includes wifi off, gps off, and auto backlight dimming off.
Advanced Task Killer also helps extend the battery life.
gotta say for how snappy it is, the clarity of the screen, and no lagging..this compact smartphone with it's smaller than typical smartphone battery packs some punch. VERY happy with the upgrade to Android
I wonder if there'll be an extended battery for this thing that doesn't require an enlarged back. I remember my Tilt had something upwards of like 1800mAh that was the same size as the stock battery.

i only have a few that run on the homescreen other than the ones that were pre-installed there.
If you plan on using the phone for anything other than an occasional phone call, you will need to charge it at least once before the end of the day. I just got mine a few days ago, so I've been spending a lot of time toying with it, listening to pandora, downloading apps etc... It's almost 3pm and I'm at 30%. I had the gps on while I played 18 on Sunday, used it with freecaddie for a half decent rangefinder. It made it through the round, about 5 hours. I had to charge it when I got home, battery was at 15%. I think it's fairly typical for a smartphone, a spare micro-usb cable at the office and in the car are certainly going to be a necessity if you are a heavy user.
So Samsung Omnia 7 or Focus owners, how is the battery treating you on the phone? I'm going to switch to AT&T for this phone, but I want to make sure battery life is good too on it!
Based on your "average" use, how much battery life do you get? You can make it like 1 and a half days? Barely make it through a day? 2 days??
Thanks everyone! Vote in the poll, but I'd rather here your written opinions!
You seem to be missing the Lasts a Full Day option...
Could people post whether their usage is using push or not? Been hearing some heavily varying battery life from people and personally I need this phone to last a full day on push.
My finding so far....
It doesn't last a day doing what i want it to. But I do a lot with it, bluetooth music for hours, wifi when at home, games at breaks, facebook checking, marketplace scanning, phone calls, plenty of texts and email (set to 30 min)
To be honest it does very well, would be handy to get some app that shows % of batt and estimated time remaining.
It does seem to take quite a while to charge from nearly flat, the Omnia 7 has a decent sized battery. In order to increase the battery life i've set the tiles to red, I seem to remember reading a while back that the power consumption is reduced when displaying red for some reason or another. Will keep you posted if i notice a measurable difference to life.
I tend to charge the phone overnight, and by 5/6pm the battery icon is pretty much empty and i give it a boost for an hour to see me through the rest of the evening before getting its proper charge at night.
Remember batteries tend to take a few days/weeks to reach there maximum performance.
Sorry for the disjointed post but its whatever comes to mind as i type lol

Well, the "Lasts a day and a half" covers lasting a full day. If your phone barely lasts a full day, then you would pick the first option. If it lasts a full day pretty well, then you would probably have enough juice to go another half day, therefore you would pick the second option.
Thanks for your feedback rlatarche! Yeah it might be true that the battery needs to settle in and be better calibrated, after being drained and recharged. That'd be awesome if your battery life improves sometime!

But what if you have, say 15% left at the end of the day. That's not enough for another half a day, but I wouldn't say it's barely making it a day.
Depends on what you mean by barely.
Of course, I'm only messing with you.

Haha I guess. There's no way to edit polls though, is there? I couldn't find the option to at all :/
I can play music for a couple of hours while commuting, surf occasionally throughout the day over Wifi and still have plenty of charge left by bed(charging)time.
Of course, the joy of not having a sealed phone is that you can always buy a second battery
Battery does not last long at all.
Im a pretty heavy data user. Email, Attachments, Browsing, Wifi, Etc. Fully Charged this morning,its now 3:00PM and it needs a charge. barley see the white battery level on the display.
I have added a 16GB Class 2 Micro SD card. Everything is working fine. I hope this is not a related issue.
Anyone else experiencing this as a heavy user.
Overall im very happy with the phone. very fluid and easy to use. Great one handed operation.

I think the battery needs a few charge cycles to attain its full capacity. Also I think it is suggested that you charge the Li-ion batteries very often first few days and don't let them deplete completely.

Well I ended up getting the HD7. Battery life isn't great over here either. I got through until like 6:00 tonight, from a morning's charge. As the other guy said, the batteries might need some time to train themselves.
The problem with battery usage on the Focus and the Omnia 7 is the S-AMOLED display. AMOLED displays have different power usage depending on what is showing on screen while LCDs tend to have pretty much the same power usage no matter what is showing.
If you're seeing a white screen on your Focus, it's using about 3 times more power than the same screen on an HD7, for example. That means that if you spend most of the time looking at websites, the mail app or the facebook app, your battery will last less than on a phone with an LCD display.
However, if most of the time your phone is on standby or you're using apps with a black background your phone will last a lot longer than the HD7 also thanks to the bigger battery (1500mAh vs 1230mAh).
Last night my Focus received a full charge.
Took the phone off the charger at 7am and needed to put it back on at 7pm.
2 hours of phone calls.
Gmail (Push, 45 emails 1 attachment)
Texting (40 texts)
Light browsing of the web
I have had some accidental camera button smushes and that turns the phone on, and it doesn't go back to sleep, so that could be some drain.
I used it on Nov 8th from desk at work with it plugged in to wall charger. It took nearly the whole 9 hours I was there to charge the battery while I was using it. I was using it VERY heavily. Due to MicroSD issue (Lost everything on power cycle) I had to re add apps over the air. I streamed & downloaded from Zune, had all 'use location' features on, activated find phone fast feature, linked 4 email accounts, I pretty much got paid to play with my phone all day.
Nov 9th, I woke up with full charge around 7am. Didn't use phone much till got to work 9:45am. Today I left it unplugged from wall to test battery life. I streamed from Zune and Last.FM, and had 43 minutes of phone calls, 47 text messages, 11 of which had pics attached, and used map with location and traffic on when I went to lunch. Note the screen is off during music streaming. I also used a very simple $10 Logitech 2 speaker set that plugged into my phone, with phone volume on 20. When I got into my car at 8:15pm I still had life in the phone. I assume that using the external speakers greatly reduced power drain on phone. I have a spare battery and wall charger. The wall charger takes about 5-6 hours to charge a dead battery. I'm not sure yet how long it takes the phone to charge the battery, since I sleep while its doing it.
Mine is almost dead by late afternoon.
I shouldn't have to shut all the extra like wifi, bluetooth, location and dim the screen just to scrape by for barely a day. It's either the OEM batteries, or inefficiencies in the WP7 code. Since no 3rd party apps can run the background, I can't blame them...yet!
Hoping to get some good feedback from those who have used the epic for a couple months or more. Now that you're probably using the device normally, as in not attached to it all the time, how is battery life? I've heard initial reports that it's not so good... Also, for those of you who have updated unofficially to Froyo, does the upgrade help with battery life? Can anyone comment how Epic's battery compares to EVO's?
Thanks.
I usually get about 9 hours in my stock battery and 6-7 on my cheap eBay ones. Overall idea say meh, its about on par with most other android devices. I'm running the stock dk28 leak as well with no battery tweaks or mangers of any sort.

On most of the DK28 roms I'm pulling a solid 10 hours with moderate use. For reference, If I leave the phone on standby all day in my house it's lasted 23 hours, if I recall correctly. Honestly that's pretty damn good for a smartphone.
EDIT: I don't use any battery-manager or powersaver either. Brightness = Auto, bluetooth/wifi/4g/gps = 1 is on at any given point in time usually. Google auto-sync = on as well as touiteur (twitter) and facebook notifications every 15 min.
I have been impressed by my battery life actually. I can't speak for the EVO(although maybe soon since my friend might give me his as a backup). I can usually get between 4-5 hours of play time(surfing, texting, apps, music, wireless tethering, movies, etc) The rest of the time it is usually idol. I usually charge it over night, unplug it around 7am, then plug it back in around 11pm. At 11pm, I usually have between 10- 30% battery left.
I just switched to a froyo ROM(bonsai, which is excellent) and so far the battery seems to be about the same. By lunchtime 12:30 it is usually between 70-80% and right now I am at 72% but I also had some extensive time testing the tethering feature.
To be honest, I had a blackberry, and the battery life was a little better, but the features were not nearly as good. It amazes me the battery these things get with that amazing samoled screen.
disclaimer: I do not play games outside of sudoku and spades, so my CPU does not really get challenged, which probably accounts for some battery savings. Oh and I use regular wallpapers, cause I don't really like the live wallpapers.
Im on 2.2.1,and I have to say I see a 40% increase in battery life compared to 2.1,and thats about 11-12 hours,no battery saving apps either,well except setcpu,which does help,but its set at 100mhz - 1ghz conservative.And I use it more now then when I got it,I havnt got tired of it at all.I have noticed the first 10% goes the fastest,and I have calibrated twice since moving to the ROM im on,and its the same in all,so if you get an Epic dont let that scare you.

I've had an Epic since a couple weeks after it was released and I think the battery is probably working the way they meant it to, which means a solid day. I charge it overnight, unplug it when I go to work, plug it in when I go to bed, and I'm usually at around 40% by that time with moderate use. I don't generally have problems with battery drain.
The exception to this is when using GPS with the screen on. It's really difficult to use this phone as a direct PND replacement even though it's basically made for it (especially with Froyo, which fixes the GPS lock issues), because the screen and GPS together will drain the battery from 100% to 0% in about 40 minutes. My dedicated PND, by contrast, will give me 8 *hours* of continuous use on battery power.
Also, I have a 1000mah car charger and even with that connected, the battery still drains when using GPS and the screen (it just drains slower). I have to just turn the screen off when I know I won't be needing to make a turn for a while.
The one thing I wish about the Epic is that it had a regular old LCD screen. The AMOLED screen is the one battery killer - you really need to watch how long you have it on. In normal use it isn't much of an issue, but you just can't do much of all the cool things they advertise that you can do with this phone (like GPS or watching movies).
I do also keep my screen turned way down, which makes a difference, but it's still a killer.
Well, I reported over in another thread that with Froyo, and basically having my phone sit around and do nothing with no WiFi, GPS, Bluetooth, no "fixes" such as switching to airplane mode or killing the DRM service, and no "battery saver" programs, I was able to get 108 hours on a single charge with the stock battery (1500mAH). That was with the screen on time of about 50 minutes and talk time of about 40 minutes... (pictures here)
It all boils down to how you use your phone, but in a stock configuration, the power management seems to be better on 2.2 than 2.1 as shown by the large amount of "idle" time I was able to get on a single charge.

I don't disbelieve that - in my post above, when I'm talking about draining the battery with GPS and the screen on in 40 minutes, or when I'm talking about having 40% battery left at the end of a regular day, it's almost always with a screen on time of 30-40 minutes. So 50 minutes sounds about right to drain the battery completely, with nothing else on.
I'll bet if you had 0 minutes screen on time - just let the phone sit idle - you could have probably gotten 200 hours or more.

No I know, I was more just clarifying so it didn't seem like we contradicted each other. I think the important stat is really screen time and then any extra radios you have turned on. Just with the regular radio and nothing else, you could get ridiculous battery life on the Epic. It's the extra radios and screen that kill it.
My phone gets me through the day. About 20% down in 7 hours on standby, so thats decent. Heavy usage with full brightness on and live wallpaper starting in the morning, stopping at like 6 A.M...it'd probably die there, for me at least.
The battery is good; I'm running the dk28 rom but it really hasn't affected my battery life at all.
On phoenix kernel i was getting 20-36 hours moderate to light usage. With acs xtreme kernel I'm getting 12-20 hrs w/ moderate use.
That's about 3-4 hrs of screen on time, 45-60 min of talk time. Emails, text ing, twitter, xda, and some various forum reading. Angry birds if waiting in line somewhere..
Note: I leave background data turned off and manually sync/refresh mail/contacts/data. I have no need/desire to be alerted evrytime someone updates twit/fb. I also use juice defender.
Sent from my SPH-D700 using XDA App
I can barely look at my phone on full brightness - it hurts my eyes with beams of awesome.
I get between 13 and 16 hours depending on how much Angry Bird time I put in that day. If I'm doing normal browsing, facebooking, etc then I'll be closer to 16, but gaming drops my battery like a rock.
Thanks for the replies! I think I'm convinced a lot of it has to do with how you use the device. Pretty much how it went with the EVO when it first came out... lots of people complaining about battery and then it kind of faded once everyone settled down. All I need is to get from early morning to right before bed.
GPS with google nav is a killer on any Android with decent screen size and resolution I think. Anyway, I thought SAMOLED is supposed to save a little battery? Or is that only if the background is black? In any case, I usually dim my screen to 30%, keep GPS off, keep auto-updates down to a manageable size, and use some other tricks to save battery, so I should be good to go.
I tried to thank all of you with the new thanks button, but didn't realize there's a limit per day haha. I'll finish it up tomorrow.
As far as I am concerned the battery life on DK28 is amazing. I use overclock widget set at 1000/200 screen on and 400/200 screen off. I can pull more than 30 hours with multiple phone calls, texting, email, web and games for over an hour. Here's the screen shot I took today before putting the phone on the charger.
I've noticed a substantial improvement in battery life since upgrading to 2.2. However, I also began using the Epic Experience ROM shortly afterwards, which boosted it even further. That, plus Juice Defender nets me a perfectly acceptable battery life.
I used my phone heavily today and still got about 18 hours out of it before plugging it in before bed at a 35% charge. On top of that, my phone's never felt snappier.
whoa, is it normal for the epic to take 3.5 hours to charge? If so, any explanation? Past devices i've had tend to take an hour less... Running 2.1, does Froyo help?
Currently on Epic Experience with SuperPower installed. I unplugged the phone about 16 hours ago and it's sitting at 36% with light voice and moderate SMS/data use.
Battery life definitely improved after upgrading from 2.1, even with light use it would be dead in under 12 hours on stock 2.1/DI17.
How to get unbelievable battery life
I have some very VERY helpful hints of great battery life for the Epic 4g. (as i am on hour 26 to 28 and have 20% left with about 1 to 1.5 hours of screen on use.)
First off, use black, or almost black background. Our screens are superAMOLED. This means that if the screen is showing black... those particular black pixels... are simply not on. If you have the home screen black, and have no icons on it, then the status bar is all that is using power... maybe 6 or 8 percent.
Next, Lose the brightness. A few helpful hints on this. 1) uncheck the autobrightness in the display settings 2) turn the brightness down in the display settings 3) If you slide your finger from right to left across the status bar at the top, the screen will dim, if you slide your finger from left to right, it will brighten(this causes accidental brightness 4) cover this light sensor on the right side at the top (I believe) because the phone seems to have a problem always autobrighting even with the uncheck in the settings. This is done best with electrical tape, or perhaps finger nail polish. These things should ensure to always be at minimum brightness
Next, Install Frankenstein Froyo Rom(lightest rom=less cpu usage/blackest rom=less screen battery usage), And Genocide Kernel(undervolted)
Next, install task killer(keeps the rom at optimum efficiency meaning less cpu usage assuming you are killing the apps 3 or 4 times a day) install set cpu(This allows you to limit the cpu clock speed(400mhz is optimal usable and battery settings)
Things to remember, ALWAYS TURN THE SCREEN OFF.
If you pick it up every thirty seconds to see if you have a text, then just sit it down... whats happening now.. The screen is staying on for another 15 seconds probably. DUH!!! bye bye battery!!
TURN OFF THE SCREEN BEFORE YOU SIT THE PHONE DOWN!!!
Turn off gps when not in use.
Turn off wifi when not in use.
Turn off 4g when not in use
Dont use it as an mp3 player.
Dont talk on speaker phone.
Those last few were pretty obvious.. but some people need to be told.
I Hope this helps anyone looking to conserve battery. Follow these steps and i promise 24 hours plus ever time and often as much as 48 hours.
Enjoy
EDIT****
By the way, When you set yourself up with this rom, you are making your phone TWICE as fast... LITERALLY. Hard to believe that a ROM could be twice as fast.
With stock android2.1 this phone gets 800 to 900 in quadrant(benchmark tool/tell how fast your phone REALLY is) Stock android 2.2 quadrant score is a little better scoring as high as 1000.
With this setup, i have gotten as high as 1950 in quadrant. No joke. This is reflected as you cant even tell the phone is clocked down to 400mhz without heavy apps and REALLY paying attention.
I used to get about 8 hrs of use before having to charge. Battery would drain even when I wasn't using the phone. Since flashing to DI18 a few months ago battery life has been great. A good 15-17 hours of moderate/high use and minimal drain with the phone on standby.
I lower the brightness all the way, end the DRM process and do the TWS trick after a reboot. No fancy battery management app that disables all your phone for the sake of battery.
I expect 2 hrs of the screen being on before my battery gets down to 20-30%. Which I think is very reasonable for moderate to high usage.
I'm hitting 41 hours and still have 19% battery life. I noticed it took around 10 full charges before my phone started to get this great battery life. I've been using it as normal and even listened to howard stern for a couple of hours yesterday. Talked on the phone a bunch of times around 30 texts and even used my 4g for a few minutes. I've never had an andorid phone last this long for me even when I had my Optimus S which I thought was awesome.
Anyone else getting this awesome battery life? I'll post screen shots when its about dead as I dont want to plug the phone into usb to get the pics.

I would investigate as that shouldnt be. My shift lasts almost 2.5x my hero. I bet if I had your phone in front of my I could find out whats killing it soo fast.
Is your phone getting hot? I would do a full system wipe and start over from scratch and see if it doesnt get better after you try the things I've listed below. Note, I didnt have this great of battery life until 6 days after I purchased the phone and charged and discharged numerous times. The first few days the battery life was not good at all.
A little list of things to do, check and or disable;
1. Use spare parts and find out whats killing your battery ie partial wake usage, cpu etc.
2. Turn your window animations from all to only some animations
3. Turn off automatic display and keep it around 20-30%
4. I have auto sync off on all my appz (E-mail, Gmail, Facebook etc.). I update my E-mail and such manually.
5. Turn off data when not using it. I find data accounts for around 15-25% of juice used and thats just when on idle.
6. Only use widgets on the homescreen if you really have to (Running widgets use a lot of power over time)
7. Use Android Hackers tool from the market and it will break down how long your cpu was in a certain state. ie my cpu spent 65% at 245mhz and 28% at 806mhz.
8. Keep off 4G, Bluetooth, wirless networks for location and GPS if not using it (GPS uses less power than wireless networks and is more accurate anyway) I assigned Quick Settings to open when I hold down the search button. That makes it easy to enable/disable any of these setting within seconds.
9. Turn off google talk and make sure it doesnt sign in automatically (most people dont realise this)
10. Turn screen timeout to 15 or 30 seconds (if longer your phone can keep the display on accidentally while in your pocket if a button is pressed, wasting power)
11. Dont use a task killer unless its to kill an app you know drains your battery and therefore must be closed to save juice
12. Check your apps. Some apps keep using cpu etc because they were not programed correctly. (some appz I've found to drain my battery are; Yahoo Mail, Craigslist, AndTorrent and the market if a download is hung up. There are a few others I cant remember off the top of my head) If your phone is getting hot for no apparent reason this may be the cause.
13. Calibrate your battery by bump charging (charge your phone till its full while on, turn it off and charge till its full again. Then bump charge it around 5-7 times) Wipe battery stats if applicable. If you have a car charger, plug your phone in on the way to work to account for the little bit of drain that occurs once the phone is fully charged yet still on the charger.
Remember you can get china made batteries for very cheap. I paid $12 for 2 batteries and a wall charger off ebay. This phone uses the same batteries as the Hero and Evo by the way.

I find that Battery indicator doesnt draw much power if any as I've always used it and never had a problem. The maker of the app states it uses no extra power. I love the circular battery indicator version found in the market. Its not a widget, it stays in the upper left corner of your notification bar. You should give it a try.
Phone doesn't get hot. I've started from scratch twice, I've ##DATA# reset. I had terrible service and data speeds before I did that and it did a number on my battery. Now it'd fine, but it just drains while doing nothing.
I never use task killers or auto sync, I live with spare parts and and monitor it, no real partial wake usage to speak of. I know how to save battery, my hero get 20+ hours with use and auto-sync on.
I'm thinking my battery might be bad. Feels like your talking down to me too, captain.

I haven't had mine a week yet, but atm I'm not getting half the battery life I did outta my Hero running AOSP's Gingerbread alpha.
I'm blaming the crap bloat that's part of the stock ROM.
With the display set to 15-20% I've got the display accounting for 69% of the battery usage. :/
Turning off sync is not an option and I feel defeats the purpose of a smart phone. Additionally, I fail to see the point in paying for 4G and not using it. (I do turn it off if I'm out of area for it or don't expect to be using much data.)
So thus far I'm disappointed in the battery life... but still think it'll improve vastly once rooted and cleaned up.
EDIT: Just did a test running Angry Birds for about 10 minutes... maybe 15. It ate up 9% of the battery in that time. Added another 1% to the display usage.

hey that's really impressive. I thought my 20 hours battery life was pretty good...kudos to you.
def getting better bat supply. especially from my hero which only lasted about 6-8 hours, just got my shift yesterday afternoon. from a full charge: Constant texting, facebook, Zenonia 2 (Downloaded wifi), Snes emu + 11 roms (3G), and customizing it to my hearts content. almost 12 hrs later had 20% until i plugged it up at work.
so far this thing is a golden brick to me
Just out of curiosity, how do you calibrate the battery? Just in case my battery life doesn't match the reports (I know my luck )

Its under # 13 on my 3rd post.
getting great battery life isn't that surprising given you've got a 1500mah battery much like the evo and epic however 48 hours is rather impressive.
Sent from my cm7 Evo 4G!
Working on calibrating my wifes battery and damn this thing is hard to kill. Even with with everything running for 5 hours its still over 20% finally decided to bring out the big guns. Turned on navigation and the flashlight. I'll post when I see the battery life after calibration.
Sent from my cm7 Evo 4G!
Edit: Phone plugged in at 7:53pm PST. Now to see how long it takes to charge.
Edit #2: Phone finally fully charged almost an hour after my evo finished its 0 to 100 at 12:19am
Edit #3: Holy F***. This phone takes forever to die and to die. Finally on the second off charge. I wouldn't still be doing this but for the fact that its saturday.
I have been letting a couple of days go by to see how the battery is and I have got to say that I am highly not impressed. I love the phone and even like Blur but the battery is really a let down. I know that the first day or so that I use the phone heavily because of course.. ITS NEW. But today I have been real busy at work and have maybe text a few people, made 2 calls, and looked up a number using google maps and my battery is now down to 60%. In battery manager, it says 5h 2m 25s since unplugged which would be me taking the phone off the charger this morning and heading to work. Other stats are:
Display 35% 29m 52s
Phone Idle 26% 4h 32m 47s
Voice Calls 24% 6m 45s
Cell Standby 11% 5h 4m 5s
Wi-Fi 6% 1h 51m 56s
From looking at these battery stats and usage, does it even seem correct to be at 60% battery? This is at the least very minimal usage for a phone.
Yet another battery thread... One thing before people start complaining: don't estimate battery life based on battery gauge! Complain once the battery is dead and you HAVE to charge. That's the real mileage you'll get from your battery (and give it a few days to calibrate). The gauge is not a good indicator.
I am a new Atrix user too and so far the battery life is 12hrs or less. Maybe that is not impressive. Coming from the N1, its alright in my book.
I do want to say to everyone complaining about the battery life:
It can take a week or more for the battery to settle into the routine and perform to its maximum ability. Lets start the conversation again later next week on where our battery is at.
Yesterday I got 13 hrs between unplugging the phone, and getting the 15% warning. Not all that bad. Not great, but definitely could be worse.
mine has yet to drop below 30% and im pretty much browsing the web and texting all day. I dont care what kind of phone you have but making voice calls and playing games/watching videos kills battery with a quickness no matter how big a battery you have. . The atrix in my personal usage is just as good as my ip4 was.
the atrix was very good on battery life compare to other android phones i've had
Have the Atrix and Epic 4G and the Atrix lasts easily twice as long as the Epic.
I have to keep he Epic pluged in for my hour comute with pandora, just to make sure I have enough battery to make it for the trip home. Normal usage during the day with brightness all the way down, wifi off, BT off, sync On.
Had the Atrix today (day one after full night charge, unpluged at 6:30a), kept BT On, WiFi On, Brightness 100%, Sync On, Exchange Sync On, Auto off/standby set to 15 minutes, Pandora on via BT for my hour trip (unpluged), forest Live Background, Weather Widget etc.,downloaded everyting I could think of/find, constant e-mail, and constant "whatsApp" till noon (lunch), wache YouTube Videos for my whole hour lunch (still full bright mind you). Created 10 minute Install Video with 720p for work, then uploaded via WiFi, not USB. More Texing, Calls and Downloads. .... FINALLY haed to plug it in at 2:30p, with 5% battery left, I think I could have made it till 3 for sure.
That's a full 8 hours of NonStop Use of everything. I expect to get Morning-Night life from normal usage.
Final word. Test it first. I did and it's Great, not just good. The receiving end of all my texts and e-mail blasting and video look ups has an iPhone. He had to charge his at 2:30 too, but has his iPhone set to max battery save (brightness 15%, wifi off, sync off, etc.) But was using as intensly as I was
... okay I'm done ...

Well I must have a bad battery or something then because I am not doing nearly half the stuff that you are doing and am now at 30%. Is there any special charging methods or anything that I should try to squeeze out a few more hours on this puppy?

may be you have several internet connected background service running behind the scene?
My attitude towards the battery is a mixed bag.
1) PRO: It blows away the battery for the Eris (which I'm coming from)
2) CON: As these phones come to be computers with phone capability, it's really time for manufacturers to try their hardest for better batteries. I'd eagerly accept a phone twice as thick as this one if it meant double the battery life.
I find mine is only good for 10 hours (much less with heavy usage, but low calling time). I expected more.

I really call bull on this.
Coming from the world of Airsoft, I'm no stranger to battery performance.
Most of these performance myths are hold overs from the Ni-Cad days and don't apply to modern batteries.
Call Bull all you want. But it was true to the N1 and so far its been true to my battery. It does not last the first few days and gets better after a few charge cycles.
Frankly, everyone believes whatever they want on batteries. I for one take it as a user by user experience. I watch my battery life a lot, but I also like to have Google Reader and Google Listen syncing.
I'm at 30% right now and 12 hours unplugged. What I wouldcall moderate use. Its not as good as my captivate on custom rom / kernel but its far from bad enough.for me to complain about

Andriod sucks the battery, bigger battery on Atrix didn't help much. Google need to optimize the OS for better battery management. I am disappointed coming from Samsung Focus & iPhone 4, both have superior battery life. BTW, I am on Day#4, conditioning the battery didn't help any so far..
Within Range
Looking at all the comments - I would say the Atrix is within range -- I knew when I saw the 1950 mAh (or whatever the exact spec) that the tegra processor must really be a power hog -- the new processor, along with the huge screen is going to draw a lot of power. Comparing to other phones with single core processors and screens even 20% smaller is not reasonable.
Definitely a good point... going to be interesting to see how well other dual core are going to hold up. That will be a better comparison.
Is that battery really a 1930mAH? The size looks like any 1500mAH battery isn't it?
I managed to get close to 16 hours of 'normal' use, meaning I wasn't trying to drain it, nor was I trying to conserve battery. I took the phone off the charger at 3pm and made it all the way to 2pm the following day with about 20% left. That's 23 hours, but I subtracted out the time the phone was on while I was asleep, 8 hours (nighttime mode).
Hmm hearing all these replies i believe i have a defective battery. I unplugged mine today at 5:15AM and now it's 2:18PM and it's just gave me the 15% beep. I've sent about 25 texts and played some words with friends. I've got watchdog installed and no apps seem to be out of control. I'm wondering if a factory reset would fix the issue or if i should return it.

try going to your dialer and entering *#*#INFO#*#*
Look under the battery usage and check the different items. Is anything using a significant amount? it could be a rogue app.
I will say MotoBlur has a lot running in the background. About twice as much as vanilla android.
I have turned most of this off and I do know that is helping my battery life.
