I know that there are lots of these battery life threads and i have read most of them and I've tried closing processes that i don't need and i have tried setcpu to keep the cpu low when the device is off, which seemed to help some but my phone would shutoff randomly. So last night i had a full battery and went to bed when i woke up 8 hrs later i was at 20% so about 10% an hr not even using the device. I have attached some pics for reference does anyone have any thoughts that might help. Thanks
I don't know about galaxy S but on my X10 the problem was wifi.
When I didn't have a data plan I had wifi on all day and the battery was down in 10h max 12h.
To improve it I had to use JuiceDefender to enable wifi every five minutes for updates..
Try to disable wifi overnight, reboot the phone and see what happens.
By the way, what app you used for those stats?

I don't have wifi enabled, I don't use it that often. the name of the prog is system panel
Very weird indeed. I have my Captivate with Wifi on all day, GPS signal and auto sync and when I go to bed and wake up, the battery hasnt gone down at all. I had the phone go on full battery one day and I even sent a few texts and went online for 10 minutes before it lost just a bit of battery.
Do you have that one LED app installed? The one that shows a little red dot on the corner of your screen when you have a notification?

yes i do.. Why? but it was turned off last night, as its turned off every night
Ok so i tested again last night and I did not have my im+ app running and the battery life was soooo much better. I also did not have system panel running which records all the battery and cpu stats but i'm think its the im+ app that was taking up all the juice. Can anyone think of another app that does skype and facebook but that also does not take up sooo much batter life??? Thanks

Open up the dialer and type in *#*#4636#*#*
Go to BATTERY HISTORY>PARTIAL WAKE USAGE and maybe that will show you which app is sucking up your battery life while you sleep.
Also try, if you don't absolutely need an internet connection while you sleep, SMODA widget to turn off your mobile internet. It's quick, free, and painless.

I have the stock ROM and stock launcher and my battery is awsome! 8 hours and I will still be above 80%.
Brightness: Lowest (manually control via stock stock gesture)
GPS: OFF
Wifi: ON all day
BT: OFF
GMail manual
Other emails accounts hourly for the most part.
Widgets: Google/Fancy Weather
BG: Mostly Black
I have never seen such good battery life on a smart phone.
I could easily get 2 days, but i rather charge every night and then not worry about battery usage.
The wifi/gmail/gps made a big difference, its too bad you can't set gmail to hourly or something lik e that. Some of my email accounts i would like to set longer than hourly.
The last few days have been pretty good one my phone. Used to get maybe 16 hours but my last charge lasted me about 50 hours with moderate browsing, gaming, and voice/text. Juiceplotter is telling me I'll be getting about 47 hours

How many hours with the display on?
Sent from my phone so I apologize for any spelling mistakes
My battery icon depletes one notch when I'm using the screen for about an hour. Some people recommend cycling the battery, in which you do a full drain and immediate full charge, 3 or 4 times. I've done it, but it's hard to say if it explains my good battery life.
let the battery drain COMPLETELY until the phone turns off a couple times, then charge it till 100% without unplugging it.

You don't want to drain the battery that much, those kind of batteries can be damaged. The phone turns off for a reason.
I haven't done the cycle thing and its fine. A lot of that comes from older batteries with the memory problem.
irus, software which is based on data connection drains the battery one way or another. Some apps now support push notifications and IM+ does too. Did you try to use push?
These claims of multiple day charges with moderate use is crazy to me. I have the newest ROM, a black screen, display all the way down, gps off, wifi on when in range, make zero voice calls, run juice, and only have 2 widgets that update every 4 hours. I use my phone for a maximum of 3 hours browsing the web, reading XDA and feedR, checking facebook and the occasional text message. My phone lasts a total of 12 to 14 hours. My battery has a manufacture date of late July. Is there some secret I am not aware of?

There is something worn here. I'm using beta4 a in nearly 24 hours with WIFI, GPS and heavey navigation i am on 38%, Maybe you guys need to calibrate your battery and erase battery stats:

That's not what i asked about..
I asked which one fixes the lags better not which one gives more battery life
Hello I am new to this forum, I just got the Samsung galaxy s 4g this Wednesday and I was wondering if anyone else was having battery issues. Right now I have my phone set to minimum brightness, auto sync off, black bckground and juice defender on. So I don't understand why am I getting only about 3 hours of battery life when all I'm doing most of the time is surfing the web(this forum) and facebook. I even get better battery life from my dads vibrant which is completely stock, has auto sync on, no juice defender, and screen brightness set to 50%. From reading the stats of both phones, the vibrant 4g is supposed to have a slightly better battery. I also don't understand why if the screen is at the minimum it still takes up 94% of the battery whereas on my dads vibrant 50% screen brightness takes up 30%. Is there anything I can do? Will wiping the battery stats help? If so how do I do that from a stock unrooted vibrant?

Check your notifications settings. I know that Samsung's contacts integration with social networks takes a big toll on the battery, hence why I've disabled it. Also, disable T-Mobile's Contact Backup Sync, just use Google's contacts integration.
Thanks for helping, but yeah I have those disabled already.

Does the trick to fully discharge and recharge 3 times work with these batteries? According the the Li-on technology this is not supposed to be necessary but I've heard stories in the forums of folks getting great battery life on other phones after doing this. Many people also say their batteries work a lot better after a week of use (supposedly after "training" them as well.)
I believe the G2 is clocked down for this reason. You could try CPU-set app, clocking down to 500-800mhz when not gaming.
Anyone tried these tricks?

Im having the same issue with battery life.. for me its a deal breaker.. I use my phone pretty heavily for keeping up with email and a little web browsing as well as talking quite a bit.. My iPhone 3Gs lasted me all day of heavy use and with the SGS4G I have to charge the damn thing at least once a day with light usage and if I have to be on the phone a lot then its twice a day.. Not acceptable at all...
Thats with wifi and gps disabled..
On the 3Gs I had wifi, bluetooth and the gps running all the damn time...

I'm not having any issues with battery life or heating. I use wifi teather most of the day and I'm getting to use it all day without issue. I did cycle my battery 4 times already just in case it matters. FYI
The batteries that our phone uses DOES NOT require u to cycle the battery. In fact, doing so will harm your battery. To avoid damage to your battery always charge ur phone when u r at <15% battery level. Trust me I thought the same until I did the research. I will post more info when I get on my PC later.

I just bought a Galaxy S 4G on wednesday. First android device coming from iphone 3G. I'm still trying to figure out the best way to preserve the battery life.
I took it off the charger at 6:30am and the battery was at about 2% at 8:30pm.
I haven't rooted the phone yet to remove some of the bloatware that comes pre-installed.
I've got email accounts synching, brightness set at about 10% w/ a static wallpaper. Played about an hour of angrybirds throughout the day and didn't really do any web browsing with a few phones calls. I mean 14 hours is decent but from what I've read there are plenty of people getting a full day of use and still have 50% battery left.
I guess once the battery fully charges I'll put inception on, turn off syncing and try a few other things.
So I guess I said all that to say this, my battery life isn't great but it's not downright horrible either. Any suggestions would be much appreciated.
And yes I'll continue browsing all the forums to see what else I can find.
Edit:
Played through half of Inception in airplane mode, brightness at minimum. I dropped from 93% to 80% in an hour and a half. Not too shabby.
Also created a shortcut to toggle between 4G modes and Edge. I know 4G is going to be a pretty big drain so I'll see how much that helps.
I'll keep tweaking it.
this is completely true and if you read the manual on page 13- h t t p:// downloadcenter . samsung . com/content/UM/201102/20110224044646930/T959_Galaxy_S_4G_English_User_Manual.pdf it says that
"• Do not wait until your battery is completely depleted before charging
your device. Repeating this process of a complete discharge and
recharge can over time reduce the storage capacity of any battery."
right now my phone is at 23% battery level with up time of 46:46:40 hrs/mins/secs. with skype calling (around 10 minutes), text messaging, browsing the net (for around 5 minutes about 6 times a day), and talking on the phone (around 15 minutes)
the settings i did:
1. took a picture with my finger blocking the camera to get pitch black picture and set that as my background and deleted all the shortcut icons (i short, i only have a blank screen with the only 4 icons down below)
2. changed the brightness settings to 2 clicks to the right from 0% brightness (or you can lower your brightness all the way down during the night, and 2 clicks away during the day, this will save you more)
3. disabled haptic feedbacks and audible touchtones, selections, and screen lock sounds
4. disabled animations
5. disabled background data and syncing when not in use
6. disabled packet data (3g), wifi, and gps when not in use
the last two are the biggest settings that made my battery last longer.
7. i only charge my phone when it gets to 20% and the manual recommends not to use the phone while charging
i hope this helps.
and yes it is recommended to charge your battery to 100% before you turn on your phone for the first time and this is also stated on the manual.
one more thing, don't forget to set your browser's brightness setting as well

Well when I used it on my captivate it seemed it used quite a bit of power, more than it seemed to save by managing WiFi/3g. One found "green power" to be better as it is a lot less CPU intensive. Just my .02

I've been using JD on and off for a few days... It seemed to save some battery at first, but now it seems to be sucking it down. I left my Inspire on overnight and battery had drained by 50%! I also don't like how it handles wifi, always turns it off when I need it.
Been using Screebl (aggressive screen timeouts, but stays on depending on angle of phone) and Llama (location control for off/on wifi, gps, volume of ring and notifications) for a week now. Start with a full charge overnight, typical work day stats, on battery starting at 6:00 AM:
10-20 texts
8 hours wifi on (web, fb, twit, pandora, not all at once, just throughout the time wifi is on)
70 minutes talk time
background data on for syncing two google accounts, push
background data on for weather on stock clock widget 6 hour refresh
background data off for EVERYTHING else (manual refreshes on twit, fb, etc.)
end of day status: 8:00 PM 10% battery
this was best day out five, worst was 8 hours and the phone cried foul with 15% warning. I think there was more game playing that day. Otherwise very happy with the results so far.
read this.
I run AR 2.1 with juice defender oc 1.2ghz and get around 20 hours average on one charge. Turn off auto brightness and run it at about 20% also
CM7 nightly+ Faux's kernel + SetCpu + Juice Defender = 8-9 hour battery life. I have tried EVERYTHING!!! I cannot make my phone last longer than 9 hours. What am I doing wrong? I'll take all suggestions....

I do multiple emails and time o time on web as well, same as gaming. Im running the rom xboarder OTA GB, what could be my issue :/
Doing it wrong.
EB 2.3.5 + Trinity kernel
Charge your phone before sleeping. Leave it idle while you sleep, unplugged. If the battery stills drains you have an issue. If connected to wifi - shouldn't take more than 20% off your battery. If you have a weak signal, it could drain your battery.
Sounds like you're just always on the phone. Buy an extended battery. $10 on ebay from hong kong.
With moderate usage, in GREAT signal areas and/or wifi I can last 20+ hours. With poor coverage (where I work) I can't go more than 5 or so. The radio seems to eat the battery unless you have a strong connection.
set screen brightness to 25% unless you really need it. set a profile for 312 max/216 min screen off on setcpu. turn off auto sync. use your power control toggles. shut things off when you're not using them. basic smart phone theory. my battery drops 1% every 2.5 hrs. when idle. fwiw, i'm using the stock tweaked rom with updated baseband.
MIUI + Stock kernel = 20 hrs.
....
Uninstall the task killer....its not necessary. That could be eating ur battery. Im a fairly heavy user and i easily get 12 hrs on average.....mainly texting and browsing. I dont make many phone calls
Sent from my LG-P999 using XDA App
I use this phone mainly for phone calls How crazy does that sound? I get awesome battery life. I'm running stock 2.3.3 and juice defender beta 3.5.9 and I get 14 hours on moderate use. I talk about 2-2.5 hours, send 30 texts, send 3-5 emails, browse for 1 hour, stream music for 1 hour, browse the market for 15-25 minutes, and occasionally play some tegra games (no more than 20 minutes, but this eats the battery up the most).
If you want more battery life, there is a 3500mah battery with a custom cover that should keep you going a full 24hours, its cheap too, but a little bulky. They are talking about it in the accessories section.
I can do 2.5 hours of gaming or 3 hours of browsing, to go from 100% to forced-shut-down. I find setcpu made it worse during idle times. I was using faux uv/oc and I realized performace was noticibly the same when I forced it down to 700mhz, so I did. But, during standby, when before at stock speeds with custom kernel I got 2-3%/hr drain, it was draining upwards of 10% per hour with the speed forced down in setcpu. This is all with the home screen as the open app during standby.
You will find that keeping google maps open (GPS off) during standby leads to a 5-10%/hr drain even though the phone should be doing the exact same thing with the app during standby as the home screen; nothing at all.
I will use the phone sparingly and I had it run out during my work day a few days ago, very embarrassing. I listened to less than 1 hour of music, browsed 30 minutes, used maps with no gps as that is broken anyway for a total of 30 minutes, texted about 40 in/out messages, and talked 20 minutes over 6 phone calls or so. I'll warranty it for the broken gps. Hopefully there are new G2x's out by now and I'll get a new revision or something.
