Want great battery life and a stable phone?

Don't use any type of battery monitor, widget or notification.
I was getting good battery life but had a few weird cases of reboots and where the phone would just shutdown and then need battery pull to get back up.
Since I stopped using any type of battery monitor/widget/notification my battery life is much much better (same usage pattern/apps) and I have not had a single reboot or issue.
I just wanted to share this for people having problems. Worth a shot.

I use JuiceDefender Ultimate and my battery life are more efficent!

i've been getting close to 20 hours on the standard battery.
expecting my extended oem battery soon!
GSM version of course!

There are a number of things that affect this. Most importantly, use CPU spy to check how much time your phone spends at each frequency, or rather in deep sleep. Some monitors in certain settings will keep the phone awake, draining battery.

My AndroidOS wake time is much lower after getting rid of the battery status apps

I use Circle Battery Widget https://market.android.com/details?...oid.CircleBatteryWidget&feature=search_result and it has no noticeable effect on battery life.

I'm using Battery Solo Widget (was using Circle Battery Widget before) and it does not have any noticeable impact on battery life. Right now I'm at 36 hours on battery with 24% left

Do you even power on your phone during the day(s)?

Use airplane mode at night while your u sleep. I lose less than 1%

Well the screen was on for 1 hour and 50 minutes (at max brightness) according to battery stats, so I'm not using it THAT much but the point is that a battery widget doesn't seem to have a big impact on battery life.
I also noticed that if I stop constantly closing applications after using them (by swiping on the ICS task switcher), my battery lasts a little longer

and lose 100% of your incoming calls or texts. good for battery life, not good for anybody who has a job/life that requires constant connectivity.

Yeah this isnt an option, I need to see missed calls and what not
However, when I do not have the androidOS wake bug, if my phone is on wifi I lose ~3-7% overnight, which is good IMO

I went to bed last night with 96% and left everything on and syncing and woke up to 88% so I think I'm content with letting it do it's thing. That was my first night with it so I expect it only to get better.

I suppose if you work 24/7 you are correct. For those of us that don't, airplane mode is a great option. Also Google voice solves the missed call problem - you will be notified by email when you take airplane mode off.

As crappy as the battery life is during daily use...idle at night even with wifi left on and updating turned on its still only about 1% loss per hour...Also running the th3ory axiom roms too if that helps.

What if someone calls you and its an emergency? Like one of your kids calling to say they're stranded somewhere? Still a good idea? Or how about just plug in your phone while you sleep? Brilliant!!!

I run the stock GSM battery, it lasts all day so I have no complaints.
If I had the samsung spare battery w/ charger for business trips i'd be set for those flights and airport waits.

[Q] Is this normal battery usage?

It feels like my phone can't last much more than a day.
Am I expecting too much juice from my phone or is this the normal amount it should be at?
Generally speaking for me I only last about 12 hours unplugged. Even when not in use on idle, i seem to lose 1% every 10-20min or so.
Someone please shed some light based on these battery screenshots and tell me if its normal or not.

Your biggest wakelock is audio out. Turn off keyboard sounds and screen touch sounds and lock sounds. Now your phone can sleep better.
Sent from my Galaxy Nexus using xda premium

You seem to have fairly frequent screen-on usage paired with frequent intervals of GPS usage (see battery graph).
Are you using GPS that frequently? If not, id investigate on why your GPS is being utilized so frequently.
I'd say based on your usage, your battery life is fairly normal.

Two hour screen time... That sounds about normal to go from full to dead. You're lucky the phone made it 12 hours. Many people get a lot less.

Two hours screen on time is normal? I hope you mean for the Verizon version..
Sent from my Galaxy Nexus using xda premium

with wifi on the whole time, that should help the battery last longer. I'm on LTE version and my battery life is similar to yours, but on 4G.
Based on your info, I would guess that you can improve it by turning off some things going on in the background. Widgets, weather, screen brightness, anything else using lots of background data or ram?
Sleeping with 4G, sync, and GPS all on I lose 1-2% per hour. But that's with no background apps other than stock OS stuff + AVG. I normally get 2.5 hrs screen time 100%-0% on 4G over a 12 hour period.

Well there's half the problem right there, facebook, it's refreshing for updates all the time.. also, underclock your phone so the max is 920MHz might save some, unless you wanna do some gaming or something it doesn't matter. Audioout seems to cause a lot of wake time for all android phones.. seen it in the epic 4g forums. But yessiree Bob.

Normal for a lot of people. Just look at all the poor battery threads. I get 2:30h with my gsm GN running Wifi and very minimal apps which sync. My browser is inverted and my screen brightness is low.
I get good standby time, but that doesn't really comfort me as I have a powerful phone I can't actually USE.
You will hear people say they get great battery life or they are fine with 2h screen time, but I just think they don't want to admit that a $700 phone in 2012 should have better life than this.
If you ask for advice, people will tell you to stop complaining and / or get a new phone. Don't reply to them or an XDA mod will threaten to ban you. Happened to me.

With standard battery and stock ROM this phone can only give 2.5 - 3 hours screen time, which is unacceptable IMO in this day and age.
Turn GPS off, turn wifi off, don't use this app, only use that app, turn sounds off, don't increase the brightness, limit the cpu etc etc... So why did I buy a smartphone that I can't use then?

I have owned more android phones than I can count, and tried more ROMs and Kernels than you can imagine. Countless times I have seem claims of improved battery life, and until recently nothing made a noticeable difference short of not turning on the phone. I am running the latest GummyNex Rom with the Franco Kernel 15.2 and it is shocking. I have verified the last two nights by leaving phone off the charger. Night #1 -8 hours 30 minutes phone sat while I slept, on 4g GPS enabled, and used 8% battery. Last Night 8:15 phone sat, same conditions only 7% battery usage. I am using the "Franco Turtle" governor and notice not performance degradation and only incredible battery life. Very impressive

[TIP]Increase battery life by at least 50%

Here is a tip on how to increase battery life by at least 50%. For me, it has increased by 83%, given that my S II is relatively new (3 months old). It is an app in the market which you can get for free: JuiceDefender
MUST:
Remove any task killing apps (Advanced Task Killer) otherwise this app is useless as it needs to be on at all times.
I have my settings set to Aggressive, as I don't use my phone much during the day.
My normal on the Bombaridier v3.5 ROM by TricH was 100% at 7:00 AM and 88% at 10:23 AM with only 40 minutes of music and standby with no data connection or Wi-Fi. With JuiceDefender, I get 100% at 7:00 AM and 98% at 10:23 AM with the same circumstances of use. It is worth downloading and will extend battery life. I have 83% more battery life according to my math (which is (10/12)=(x/100)) and it is amazing.

I agree that JuiceDefender is an excellent product for extending battery life.
I have the "Ultimate" version.
JuiceDefender alongside "Battery Monitor Widget Pro" is the killer combination...
I did notice one slight bug with JuiceDefender (JD) - there's a known issue with wifi management. Phone turns itself off occasionally. The fix is to simply set JD "disabled" for WiFi management - problem then goes away.
I also listen to music (Pandora) over a Bluetooth headset (about 3 hours per day).
I regularly get about 18hrs+ (combination, on average: 3 hours on voice, lots of email). Stock, rooted ROM... bloat removed.

I agree Juice defender is purely amazing, according to JD stats, I get 1.83% more battery life, that's with aggressive settings.
Ps: Thanks for the Wifi tip

It'll be hard pressed for any app to extend my 3+ days of usage on a single charge. Just sayin..

I just bought the ultimate. I will let everyone know how it goes after a week of using it.

The first thing that came to mind is; haters gotta hate.
I use it just fine with my purposes.
Check/write emails, make calls. Nifty info widgets for updates. I just don't use it for everything because that's just silly. That's the reason why I get such a long run-time. I already have a dedicated media device, no need to watch videos, etc etc on the phone.
Just because most people don't get more than a day usage, don't mean it doesn't happen.

whoa 18+ with 3hours voice is killer.
i barely get about 16 with 2.5 voice and roughly 2.5 display on time
just fyi to those who don't know. voice weighs heaviest on battery usage, even more so than display.

I can get 2 days with moderate use but I dont realy tLk on the phone and I use wifi most of the time

Use the Darkside X kernel and under clock to 1128000 or something and it still runs smooth.
Sent from my SGH-T989 using XDA App

Best thing you can do to to increase battery life is to disable all those Google services. I don't know why but I make it pretty clear in the settings that I do not want any auto-update or syncing of any sort but it happens anyway, so I have to manually freeze all the **** that Google insists on running 24/7.

Thanks for the tip! Extra battery life is always welcome.

Although jd isn't exactly new, but there seems to be a lot of people who just heard of it now. Not bashing but this just shows that there seems to be a lot of new android users or well xda members since the release of our awesome device. I bet most are all former ifags (don't take me seriously).

Lmao. I think this made my day. xD I was using juice defender way back when the droid eris was new and I still do! It works wonders. When I had a dell streak I went from 6-8 hrs of batt life with no usage to over 2 days.

Sorry if I sound like a tool for asking this but if you turn off the Google gmail and calender sync then how do you get your emails?
U have to manually check for mail all the time?
sorry, having issues with my battery also. I use Juice Defender but the free version - everyone that is having success with it are you using the purchase one, Juice Defender Ultimate?

Ive had my phone since october, and the battery has gotten better and better. And im not doing anything special, stock rom, no juice defender, no task killer, nothing of that sort.
I use wifi tether almost all day at work(about 6 to 8 hours) and I still have 20 to 30 percent left when i head home.

Big tip for better battery life 24+ hours

This is a small easy fix that I use whenever I am trying to conserve my battery on the go. It is very simple I just disable my mobile network/ 3G Data under wireless settings. Using 3G/4G data consumes alot of the battery for some reason I've noticed more drain on 3G. This helps me alot with saving my battery for a day on heavy usage and I can still receive calls and text msgs. Then just use wifi when you browse or simply turn your Data back on. Hope it helps

You'd be better off with an app like "easy battery saver" which turns off your mobile data when your screen is off but still allows you to use the device when you need to without constantly toggling.

i use juice defender ultimate and setcpu to undervolt and set the cpu to 1ghz max. I havent noticed a single hitch, so its worth it for me. Also using Blazer 4.1. i never actually run my battery down since I charge overnight for the next day, but if I were to i could easily get 35+ hours on medium use.

I do that whenever I am in an area with poor signal or roaming. A Sprint phone will eat up battery hunting for 3g signal

whats your screen time? that makes the biggest difference. I went 35 hours and only went down to 51% once, but that was only with about an hour of screen time.

Best jump in battery life I've had it's flashing a modem from the ICS leaks.

I think turning mobile data off at all would be for only extreme cases where I was going to be away from a charger for a crazy amount of time. For me, the use of widgets (google reader, apw facebook and twitter) allow me to turn on my phone, flip to a few home screens, and turn it back off. Screen time for me is always incredibly low, which keeps my battery life high.

I do this when I'm running low on battery with no charging option

Juice Defender set on defaults gives me from 1.60 to 2.07 times normal battery life. I use the default Balanced settings and forget about it.

Battery life good bro, cool story

Mine's absolutely horrid, I can't for the life of me figure out what the hell's wrong with it. I'll run out of battery after about 12 hours, with the screen time at 1 hour and maybe 30 minutes if I'm lucky? The phone drinks away my battery in standby mode like a former alcoholic united with an opened beer. When I was on ICS, turning off 4G every time the screen was off with the AutomateIt app would give me excellent battery life. Ever since Jelly Bean, it doesn't seem to make a difference. I just don't even bother using AutomateIt anymore, I even uninstalled it. Useless. I check marked the option, "Restrict Background Data," but I actually had worse results with that on even. Following the thread about the Guide to good battery life, I turned off auto-sync. The only thing that seems to do for me is not get my emails in real time. No effect on the battery though. I'm guessing the battery drain has something to do with being on data (even though turning it off doesn't seem to do much) because everytime I go to school where there's little WiFi, battery's worse. Also, somehow my Messaging app takes up more battery than the screen. What's with that? I'll text every now and then, but it shouldn't eat away my battery like a fat man with the last batch of Twinkies. Enough with the dumb similes, haha, but I actually need help with this. I really don't wanna buy a battery off eBay cause the damn people are too lazy to send you the battery until a month passes, and I hate charging in the middle of the day.
I'm on 100% stock. I used to root and mess around with a ton of ROMs, but then I realized all my favourite ROMs were the ones closest to stock...

.... look at the eBay expected arrival and/or look for a seller in the USA ?
Anyway, that bit aside - have you installed something like BetterBatteryStats to be able to see what the problem is so you can fix it ?

5 hours... how !?
Easy !
I'm on stock and if I'm almost all the day on WIFI, not playing too much games, and with auto-brightness,
I can get 5 to 6 hours screen time.
(but on 4G all the day, it's more around 3 hours screen time)

This is what most people get with normal use around 14 to 16 hours and 4 to 5 hours screen time. I think the biggest issue is that 4G radio that most people have on all the time. I I have wifi everywhere so most of the time I have mine off that helps a ton. Plus all the sync stuff off, I get about 6 hours over 17 hours battery life and about 30 to 40% brightness.

14-16 is what was normal for me when I first got my GS3 (after JB update). If you want more battery life, I recommend trying juice defender (custom settings for data off while locked). If you have stretches where you don't use your phone it works really well. Just thought I would throw that out there.
