I know one of the major concerns regarding the EVO has been the battery life. It was the reason that I rooted my phone in the first place, granting me the ability to rip out bloatware to conserve battery life. It wasn't until Saturday that I got around to noticing the rooted version of the official 2.2 release. All I did was download the ROM and delete all the apks/odexes I didn't want from the zip file, load it, charge my battery. Currently, I've been going almost 70 hours and am still at 60% battery life under normal use. That's a significant increase. The best I ever got was after the rooted second OTA at about 40 hours pushing the battery down to about 10%. Have other people been seeing battery life increases like this?
No, we have not. Quit bragging..
Serious? Experiment with more use of battery life

I have noticed better battery life but not as good as you say. I've tried many different roms and kernels also.
do you actually use your phone on a daily basis? do you have any emails being synched? gmail? exchange? do you use facebook? browse the internet every 4-6 hours to see whats news on BGR or usatoday/cnn? do you text msg.. etc etc
if i leave my phone sitting i can have great battery life too, don't get me wrong i'm not trying to bash you, just trying to understand how you use phone so i can guage if this can apply to me. i know people who haven't installed one single app on their evo yet, usuage is different for everyone.....
Did you say 70 hours? Is that a typo? That's 2.916666666666666666666667 days and you've only dropped 40% battery life?

I was super nervous when I suggested the evo to my aunt's family over the iphone 4. AT&T doesn't even have 3g where they live though. Asked them if they had any battery issues with their 4 evo's and they looked me like I was crazy. Then I found out that they all only had like 1 app installed. They get great battery life on their stock 2.2 phones. If I play around with my phone, and I do, I usually am riding the red line by the end of the day.

I don't use my phone that much for phone calls, actually. Several hundred texts a month, several megs of data a month. It's synched with gmail, I have a separate phone for everything else (work). At work I'm always on 3G, at home wifi. The only time it's not actively connected to a network is when I'm sleeping (sleep profile is only for the alarm). Outside of synching, I use the internet for random browsing periodically, usually sports related, or anytime I'm not at home or work and want information.
When I put this ROM on, I stripped out over 60 files from the zip file (almost 20megs) and only installed about 8 apps that I use regularly. After I configure my phone for all my settings, I remove all the widgets everywhere and setup just three screens with my widgets.
Even though I'm in Dallas, I rarely use 4G (the higher wavelength doesn't penetrate well in the urban areas I work or live in), only turn on GPS when I'm using Google Maps to drive around, and never have both wifi and 3G (Mobile) on simultaneously. I have my profiles setup so that the only time my screen brightness is above 0 is when I'm in my car or on a need basis (separate Bright profile).
I probably would have rooted my phone eventually but I did it about the third day I owned it because of the battery life. Most of the settings and ways I use the phone revolve around making sure I don't tax the battery. My real goal was being able to leave home for more than a day and not having to worry about minimizing my usage of anything, and now it seems I've easily done that.

Hey I did not even know you could get that much time out of a single charge.... I am going at least 17 hrs before empty but thats enough for me in a full day. Hey honestly a car charger is on $13 at Walmart.
well i tried the "shut the phone off" mod and ive been getting weeks of use out of my phone on a single charge.

Does anyone know how I can find out what's draining my battery?
It goes from 100% to 85% in less than an hour. Just a little facebook and web browsing and it drains. Also when I leave it idle it drains significantly. It'll be great if you guys recommend an app or tips on how to save battery life.

Need to check your sync settings. How often are your accounts set to sync?
facebook is the culprit... even when it isn't doing anything, it's doing way too much. Log out and see if your battery improves.
I use facebook to sync contact pictures only.... just turn off the facebook notifications by going into the app, menu - settings and check off notifications.
Sent from my T-Mobile G2 using XDA App
Big help: use that app disabling method and disable app that you don't use. Biggest culprits are Google bloatwares such as: finance, shopper, listen, my tracks and many more. Also make sure you use a taskiller that works cuz most are crap and just make up fake number of killed apps. (Ask me if you wanna know how to find out if a taskiller works or not)

I have mine set to sync contacts only as well... works perfectly fine. Very little drain.
Basically, I agree with you. Don't sync notifications ... manually do that via the app if you want to.

You don't need a task killer in my opinion. Use the running services tab in application settings to disable anything you don't want running.

Taskiller is good because I prefer one app running constanly in comparison to 6 or more. The taskiller I use is the one with the red droid icon. To find out if a taskiller is good open it and make sure its not excluded or ignored then click "kill all apps" or whatever. And if the taskiller itself isn't killed then its not worth squat

Exchange email sync has a known problem for high cpu usage. I can't post the link as I'm new, but do a google search for "email sync high cpu" - it's the google.code issue #5424
Please note that there is a workaround that has worked for nearly all users. Set the exchange email sync to "never" or "push". The issue is that with specified time intervals the sync may fail and continue failing, consuming ~50% of your cpu.
I've experienced this myself, and couldn't understand why my phone was so slow till I looked at the processes running and % of cpu usage (via 'top'). I'm experimenting with never-sync and only have a handful of days battery monitoring and guessing I'm getting about 8 more hours out of my battery (again, not empirical data).
edit: I stopped using task-killers after reading up on froyo behavior and more importantly monitoring my cpu usage (again via top). All the apps that were showing "running" in my task-killer were consuming ~0% cpu. They were using memory, but I now leave it up to the OS to manage that. In the end I find that the apps that I didn't want running were eventually automatically stopped by the OS for me.
Can someone tell me the average battery life for the g2? Normally I'm only worried about battery life if I'm gone at work or out and about. Normally I just txt when I'm at work or out with people.

I have G2 my avg battery life is about 36 hours on reg battery casual usage and about 18 hours with heavy usage (i consider heavy usage data streaming from slacker, using phone as modem via wifi router 150 text messages and about 10 calls). setup i have is 2g when NOT using the phone, background data off & auto sync off, email account set for manual sync.
In regards to Task killer they are worthless on froyo devices use Watchdog app it watches for rogue app that are consuming too much power.
I have a evo battery in my current phone right now and I never worry about battery life. i did a little modifications to get it to fit but it works great (make sure you get the red color battery if thats the case, I didnt get the correct battery originally but i ripped everything off the battery it fits and it works).
Reference this thread for the battery.
Hey guys,
I'm planning to get a Galaxy S2 and I would like to enquire on the battery life of it.
My daily usage will be lots of whatsapp, google talk, sms and some surfing. I wonder if I can get through a day with this usage using stock rom.
Thanks and looking forward for your response.
Not to be rude, but there are multiple threads on the first page with several pages of posts discussing battery life. You might want to start there.

Sure it does. Go to the Galaxy S II General thread listing page, and search "Battery Life". I'm not sure what about that doesn't work as the top 5 topics (including this one) are about battery life, one of them being the thread BarryH referred to that has 400 replies.

Overall the battery life is very decent for the hardware it is pushing.... but it is nothing special. I get about 16 hours out of it a charge... it might be the best battery performance I have had yet out of an android device, but not by much! As always, it depends on what you do and how often!
It is an amazing phone IMO, and you will not regret the purchase
my battery life is great, phone can easily last a day with heavy use. Just hope you dont get the android os bug.
I dont understand how quite a few official reviews claim they got 2 full days use.
I get 12 hours with very light use, if I'm lucky....
Mine was very satisfying as it was at 45%after more than 7hours of heavy usage. No movies. But wifi surfing. And plenty of calls.

I have the Android OS issue yet can still get 2 days of use. Granted, I'm a light user like you claim but perhaps explaining my light usage would help. Phone is currently at 66% battery with 15min of calls, 1hr 30min of screen on, and currently 17hrs 30min off the charger. When the screen has been on, it's only been for texting, installing some apps, some WordFeud and taking some photos.
If I extrapolate my current usage, I should be able to get around 50 hours out of this charge.

In Qik, do you see yourself upside down? That's what I'm getting. The other person will see me just fine. I can see them fine as well, just myself, upside down.
i got 18-24hrs on mine!!
I see. But with if 3G is always on instead of wifi?
Because I would be very happy if this phone is able to last me 12 hours, 3G on all the time, background sync on, whatsapp, google talk, sms and some light surfing of browser here and there..
Can I check the bug of the Android OS that drains the battery life a common problem among all the galaxy s2 users here?
The battery life of the S2 is awful. I honestly hate it.
I am not sure if I have the Android OS bug or know what really triggers it.
Anyway when I first got my device, I charged it for about 8 hours and started using it. Installed some applications - whatsapp, waze, news readers from major news sites, twitter, facebook (from what I can remember) - and turned on push emails for gmail, hotmail and yahoo. 3G and Wifi settings were turned on. With all these running, the battery life was really bad. I could hardly get more than 8 hours in a day. Tried this for a couple of days and gave up.
Hard reset the device to stock to test what was causing the battery drain.
1st full charge (battery lasted 26 hours)
with 3G turned on, only push gmail running and made a few calls. no wifi turned on and no wifi access points set up on phone
2nd full charge (still in process)
still running push gmail with 3G data turned on and installed whatsapp and running it with an active chat group that has a constant flow of messages (averaging about 60 -100 whatsapp messages per hour). currently battery is at 67% after 14 hours uptime.
If ever I will sell this phone, sure it will be for its ridiculous battery life and for how slowly it charges up. The combination of these two issues is a real psychological break down!!!
Anyway... anybody with a rooted phone has ever tried clocking the processor down to, say, 800 MHz? Does it improves batterry life somewhat? Because I am not having noticeable battery issues in idle, but I really do as soon as I use the processor, even if I deliberately avoid 3D games and in general any sort of power eating tasks.
Hey Guys,
Not sure if anyone has ever posted this but I thought I would share how I am able to get 2 days plus on single charge...
I only recomend this if you are not totally dependent on your email, facebook, gtalk, etc to sync.
I have my email accounts on my phone but I don't need to receive them instantly meaning they are not dire important so this works for me.
Android's biggest battery killer, which most of you probably know, is data syncing in background and just data connection in general. What I personally do is keep 3G data off at all times by going to settings->wireless and networks->mobile networks->3G Data and uncheck it.
Obviously with this off, you wont be able to connect to web, get emails, download apps, etc... But if you live in a 4G area like me, all I do every once in awhile is flip on 4G from dropdown let it sync or do what I got to do then flip 4G back off so there is no connection anymore... This will save so much of your battery but it is up to you to check things when you need to....
I hope this helps some people because it helps me a lot... I always recommend this to customers that come in my store if they are not depending on work email and such...
Let me know if you have any questions!
You can hold down the power button and click Data mode to toggle 3g
I have done those things since I've had this phone in august and everytime I talk about getting great battery life the haters come out and say well you didn't have sync on blah blah. Freaking retards. Especially if you are sleeping why not turn off sync for the email that is not going to come anyways. I haven't seen the battery life yet as I did since eclair though.

It didnt matter if it was OTA or OTW...
Maybe try and get a new battery...
I think the reasons the 'haters' come out is simply because you're stating your getting better battery life and then revealing you're castrating your phone. It is a smartphone after all. It's supposed to do all those things you turn off. This isn't a phone which is only supposed to make calls. I mean, if I wanted to check my email once a day, I'd simply do it while I'm in front of a computer.
I don't believe I'm one of said-haters but possibly providing a bit of information on where they're coming from as well.
I think it's well documented that Android phones pretty much suck in terms of battery life, especially when compared to Blackberry. Man, RIM got it right on that aspect.

How is that castrating your phone? I can still do everything else on the phone... You don't need a constant data connection to use it like a PDA. Do all tabs have a constant data connection? No, so are they not going to be considered PDA because they lack internet sometimes? no
I am sorry to say but if your managing your phone and doing things to better, that is not castrating, that is good device management and what should be done so it runs how you want...

Well, it sorts of like taking a porsche and not pushing it past 2nd gear. Some people are happy with it, some are not. On one hand, battery saving posts can be thought as misleading, if the premise is that you dont compromise any functionality. I prefer to charge my phone everyday and not worry about battery, but when your battery is dying when you need it in the evening, than one is of a different opinion entirely.
One thing which I realized to late, is if you are at work in the office or somewhere with wifi, you can toggle 3G off and not lose any functionality, since wifi uses a lot less juice.
I have tried I new battery, I have three that I alternate between. I have no idea what has happened to my phone. It could be the phone itself

And I did say from the beginning what it does and what you loose from it... The only reason it was posted was to try and help people who may be newer to android and needing to squish extra minutes out of their phone for the day... Or they may find themselves not near a charger and almost dead and need their phone so turn off data to preserve the battery... I mean it doesn't "cripple" your phone to turn off data... I can still play angry birds, check my calendar, call people, text, etc. You don't need your phone to have data to use its features...

*** NOTE ***
I just realized i posted to the Nexus One forum, not Galaxy Nexus as i had intended..
Hello everyone
I thought i should share what i just discovered. I disabled the syncing of facebook contacts, and my battery usage seems to have dropped significantly.
I have deactivated the autosync and notifications in the facebook app ages ago. The only change now was that in "Accounts and sync".
The first ~8h of my battery history is during the night (see attached screenshots)
Although our devices are different, I have to agree with you on the sync and battery issues. I use Facebook a lot and would love auto syncing, but it hits the battery too hard. What I did was disable syncing in settings>accounts and in the Facebook app it's self. I noticed that my battery drained at a much lower rate after doing this. Another think you can do is lower the frequency at which the app updates; but still there will be the update service running and your battery will continue to drain.
Welcome to the N1 section
Thanks
Still waiting for the day battery issues are a distant memory..
Yea, smartphones are great and all, but battery always sucks. We need a company to create a new technology to make them smaller and more efficient. What mAh size is the G Nexus's battery?
Big screens, multiple accounts and some application polling to get notification drains battery significantly. Day will come when there ll be batteries which will last more..

It has a 1750 mAh battery.
I think a methanol fuel cell would be nice. Methanol is 15 times more energy dense than a Lithium Ion battery. The only problem is making a small and safe enough fuel cell.
I think I am having the same issue with my Nexus One running stock 2.3.6. The past few days, I've noticed that my battery has been draining very fast. Normally, I had gotten a solid two days on a charge, but now I'm lucky if I'm getting an entire day on one charge. I haven't changed my usage habits at all. I had noticed that the Facebook app had notifications enabled and was checking for notifications once an hour. I disabled notifications, but the battery drain seems to be continuing. I've checked for other apps that may have gotten updated which are looking for notifications, but nothing else seems to have been changed.
