Hi, I have just bought a GS2 and first impression, except battery life, is this device is awesome !
So, I have search and found some tips to save baterry life.
They is 2 goods apps which call :
* JuiceDefender Ultimate
* Auto Apps Kill
Juice Defender Ultimate could be configurate to do anything for you, for example if you shutdown your screen it could cut off 3G and WIFI automatically, and reactivate it gently sometime.
The best conf I have made is to activate WIFI only on some area I know I can connect ! So when I'm at home he shutdown my 3G, activate my Wifi, and if he can't do that he switch back to 3G. He will learn your Wifi position and activate it automatically.
So you don't need to care turn off wifi, gps ou 3g, he do everything for you !
The ultimate (which cost a little), allow you to handle everything, lesser version don't have this tweak.
Auto Apps Killer, is a apps that automatically kill apps you don't need when screen if turn off,
So you don't need to shutdown manually apps, he do the think for you.
Of course you can ignore some apps, and they is a default ignore list that prevent shuting down widget and main apps that maintain your phone as good as if nothing was killing.
So with this both, my baterry has almost double, I can use it a day long.
But, it seems they is more thing todo when you are rooted.
My question is, does anybody has installed the rooted roms that allow you to change you CPU frequency automatically.
Is they any gain you can have by downscale your CPU when power isn't need.
I know CPU is set to 1200 mhz, and I think it doesn't go down or high. With a rooted version I could make it slow to 800 mhz or less in sleeping mode, and up to 1500 when I use it hard.
With this I should have some extra power, and extra battery, and not worry to go to my work and get back home without any battery at the end of the day.
Does anybody has experience this ?
Umm yes, all stock android phones keep CPU low when idle and then increase CPU when you use it. Just install system panel and see. Root is not needed for this, it is stock function.
Oh I see it vary from 200 mhz to 1200 mhz
I let my phone all night (8 hour), full of charge. When I wake up and check, my battery was a 72 % !!!
my iPhone was at 92%, it seems to drop too many cpu
I have stock crap from my operator that ofen run, rooted could help me to remove this.
I have install System Panel to check what tools use my baterry like this.
I have disactivate push, and lock once per hour the connection with Juice Defender, but battery drain without any usage,
it should be less no ?
Yes it should be less. Other people leave their galaxy s2 over night for 8 hours and only lose 5%. So something is wrong with your setup.
My battery life has been fantastic. Best on any android phone i've owned. I'm just rooted with a few things frozen.

Yeah I know, it's would be a dream to save a lot of battery when it is suppose to be idle.
I can't remove crap apps from Bouygues and Samsung, so here my setting :
I have widget on :
AccuWeather,
Google Adsense,
Google Analytics,
Battery Monitor Widget,
I have tools on :
Juice Defender (which stop connection on night!)
AutoApps killer (one kill per hour)
SystemPanel (to know what use my cpu like this)
My Wifi is on for any data and not my 3G data,
JuiceDefender keep it like this when I'm at home
And everytime I look my lock screen, all data is off,
Once per hour it pull it on (and not during the night), fetch data and shut it down again.
In social hub I have :
Windows Live Messenger (but should be on only when I open it no ? any monitor don't tell me that it is the problem)
And 2 Microsoft Exange Account with Email, Calendar and Contact sync
Both account is sync once per 15 min the day, and once per hour the night
And I have twitter, facebook apps which sync sometime their data
It seems calendar in Exchange sync more often, that the over, not so sure
I know this seems a lot but it also a normal usage,
Any advice ?
I've got my SGS2 to a usage of 1-1.5% a hour in standby and 16% a hour when I do normal stuff, so no games.
I've done this with Agelom's Rom with Juice Defender Ultimate, Screenfilter and AdFree Android.
I set pulls to every 1 hour which is managed by Juice Defender, GPS off and Laditude(this kept my sgs2 awake) off.

You can also try green power free from the market, its free and can turn off mobile data unlike the free version of juice defender.
I have just disconnect latitude. I will check if battery is better.
Thanks a lot for your tips.
Next step install windows.
Install kies
Odin
Rooted
And remove all bouygues crap apps that crash all the time !

The best way to save a lot of battery is to use SetCPU and lock speed at max 500mhz when screen is off. If you lock at 200mhz after a while you have to hard reboot because the phone don't want to wake up.

I don't think SetCPU has any good effect on battery for GS II. When the screen is Off, and I guess the CPU isn't doing anything, then it will automatically run at 500 MHz or below. So there is no need to set the clock rate. I purchased the app, used it for two days at Ondemand preset, and the battery seems decreasing fast than in normal, which is weird, very weird. May be I yet to find the right setting of the appl, but till now it's not working for me and I have disabled it.
Regards.
Oh I think he has. In my case I often listen music with bluetooth. The cpu want to go above the 500mhz. So the limitation is useful. In the case I do nothing, yes it doesn't change anything.

Hi.
After my upgrade to android 2.1 my battery starts to decrease rapidly...
i had 52 percent in the night around 11 p.m when i woke up in te morning 7 a.m it was 11 percent..
Is ter a way to improve battery power..?
Is it possible to monitor which app drains te battery power?
Pls do help me..
Thanks
I had same problem. Try not to charge ur phone via pc to phone usb cable. Try and get a proper wall socket charger. And if u cant then try replacing ur usb cable.

Stop using autokiller apps. If you want to kill apps, do it manually.
I've never had better battery life since the 2.1 upgrade. Here are some suggestions from my experience.
1. Get Juice Defender free from Market, do setup and change nothing.
2. Get Startup Auditor free. Disable face recognition, download manager, google talk service, mediascape update.
3. Get Advanced Task Killer and exclude ATK, Startup Auditor and Juice Defender. Kill everything else whenever you go to lock your phone after doing something.
4. Only use Wifi when you need to, otherwise turn it off, GPS as well.
5. A 3G toggle wouldn't hurt either.
6. Use a wall charger as indicated otherwise if from PC charge in airplane mode.
7. Put your screen brightness below 50%.
8. Widgets like weather apps on your homescreen suck up batt life.
If I get into the 70% range of battery after a day's use now it's rare.
Good luck!

Try going to SETTINGS, ABOUT PHONE, BATTERY USE.
You will be able to see what the top drains are, I do not use any special apps to limit battery use and get only 4 - 8% drain over night. Leave Bluetooth off and turn off display.
Just for the record, juice defender makes no difference to battery life on either of my x10i's since 2.1.
I just trimmed out junk apps and use a task killer to manually kill a few apps I don't often use.
Finally, make sure twitter, facebook, etc are not set to check automatically unless you wish them too. I only check stuff like that a few times a day, no need for them to check x times an hour.

hi...
@Lord Takyon,Tony_C,Smoked33,pabling19,xateeq, thanks for the reply will try out the steps mentioned..
i at first had poor battery life with the x10 2.1. that was actually when i used task panel x and juice defender on it... after a couple of days, though, i figured screw it and rooted the phone and uninstalled all useless apps on it. then i just went and uninstalled juice defender and task panel x. they actually caused battery drain on my phone lol. now i have no battery saving apps running on my phone and it lasts me at least 18 hours of medium usage.
my advice is let android do the battery saving. don't d/l battery saving apps since they run in the background and cause more battery drain.
Yeah - I've been through the whole juice defender, task killer, start up auditor things..... waste of time.. they do more harm than good..
You need to use something like Task Manager (by Rhythm Software) to see what's running - set any persistent tasks/ apps to ignore, and ONLY use it to kill apps which you think are stopping the phone from sleeping..randomly killing things will at best cause your battery to drain quicker (because the processor then has to restart them).. or at worst cause instability because critical tasks aren't running.
Set auto update frequencies to less frequent.. consider how often you view the app during the day and go along those lines.. don't put too many auto updating widgets on your homescreens..

Hello
My Razr Xt910 batteries consumption is high
For example i'm in bed for 7 hours , It consumes 20%!
Idle consumption is too high
i'm using 2G
wifi and... is off
I close all programs
changed ROM
and .....
But this problem exists
In your opinion, why is this problem?
May be a hardware problem?
Sorry for bad English
Thanks
There's an app called Watchdog Task Manager that can monitor your apps and phone processes. That might be able to help you pin point if you've got a rogue app.
My girlfriend had to swap out her first Razr for a similar problem. Her phone would not last her an entire day with very light use. Using Watchdog Task Manager I was able to find that the suspend process was hanging and causing the battery to drain very rapidly.

If you were rooted you may get rid of some apps. Like if you dont use backup asst.
It always runs in the back round. I talked to a rep the other day that said just force stop it. I said duh but it will re start itself. Make a list of what you see is running in the back round and and we can figure what program it is to see if we can freeze or get rid of it. Ahh I see you tried different Roms. You can use and app like NoBloat freeze. What Rom did you use? There is more information we need and can go from there.
Edit: How to use , go to system ,apps and look at running. Do you have email setup? How often is that set to refresh for email. So many things to look at.
Install Watchdog and agree to the license.
Set the default monitor to aggressive using the pulldown menu.
Hit the menu button on you phone and go to preferences.
Click "CPU threshold" and set it to 20%.
Click "Polling interval" and set it to 1 minute.
Click "Real time polling interval" and set it to 5 seconds.
Where it says "Include phone processes" make sure that is checked.
Click and check mark "Monitor phone processes" and "Display all phone processes"
Click on "System process CPU threshold" and set it to 40%
Now Watchdog will monitor all your apps and processes and will alert you if anything is going over the thresholds you have set. You can see what the culprit is under the alerts tab in the main menu.
Also, by going into the CPU tab on the app main menu, if you check "real time CPU" you can monitor your CPU usage in real time yourself. Anything in cyan is a background app/process, white is for system processes, and green is for apps/processes in the foreground.
I still use this app quite a bit especially if I install a few new apps, although I run it with the CPU polling interval at 10 minutes and the System process CPU threshold at 50% in my everyday usage to minimize CPU usage.
The suspend process that was giving my girlfriend problems on her phone can be seen while in the CPU tab if you check "real time CPU." I believe it will pop up after your phone is unlocked but should afterward stop and not consume any CPU. On my girlfriend's old phone this would not be the case. The suspend process would hang and constantly alert through Watchdog that it was exceeding the percentage threshold.
I'm not sure if this will be of any help and I apologize if it does not but it did help me. Good luck.

ok
About 20 hours
and phone idle consumption is high
Watchdog alert:
suspend
Linux Process
43.4%
What's this?
What should I do?
You should use SetCPU and underclock your CPU so it runs slower but provides better battery life.
Switch the governor to the regular hotplug instead of mot_hotplug and under advanced change the sampling rate to 30000, up threshold to 95, down threshold to 50. Also in profiles set up profiles for various circumstances so if you're sleeping, you can make it so that if the screen is off you're limited to 300/600 mhz and so on.
I was using the ondemand governor earlier and then I stumbled upon some descriptions of them where they explained hotplug as being very similar to ondemand but having the capability to switch off the second core if there is not enough workload which I believe ondemand doesn't allow you to do.
Yesterday, I was at 65% battery left after 9 1/2 hrs of mild usage (2 phonecalls, 100 sms, bit of im'ing, light browsing and a couple of emails). Had the profile set so that it would limit clock at 600mhz when my battery is under 90% and at 800mhz when its above 90%.

Try the app juicedefender and see if that helps? a longshot but maybe its worth.
20 hours out of your phone but is that moderate usage? Forget about idle time. Do you not get regular usage out of your phone?
i have a Moto razr my own , and never noticed how much the battery would last.
of course it won't concern me much , cause i already prepared my self for a lousy battery back up with a 4.3 inch display and dual core cpu!!
i got your back on this whole messed up battery fiesta thing buddy ,
i'm gonna charge my razr up , and see how it's battery gonna react , if it's as bad as your device , chances are , it's a pretty common problem on every xt910 units , and you don't need to be worry about a thing.

after reading a few tips on the forums, I did the following:
1. installed SetCPU (paid) and made a custom "profile" that, when I turn the screen off, it reduces the CPU activity to the minimum (300)
2. I installed an app called "2x battery" (free) which will kill my data when the screen is off... I have it set up to where it will briefly enable my data connection every 15 min. to check for emails/texts, etc., and I also have it set up to where, if I have an active data connection (i.e. pandora) then it will not disable the data during that period.
3. With the 2x battery it also doubles as a manual task killer... or you can also install "memory booster" (lite = free)
4. set my wallpaper background to black
with these things I have really noticed an increase in battery power... try them and see what you think!
---------- Post added at 09:46 AM ---------- Previous post was at 09:39 AM ----------
oh yeah, after you are at 100% on your battery and have unplugged it and plugged it back in a couple times and it still stays at 100, then reboot into recovery (while still plugged in) - go to advanced - wipe battery stats - reboot - unplug and run battery all the way down till it dies - charge up without unplugging. see if that helps, it will re-condition your battery.
in my quest to get a better battery life out of my phone (seen people saying 2 days battery life) i have tried 6-8 roms, 3 kernels and 5 modems. all of which give me less then 10-14hrs usage (i know thats fairly average for some of us)
IS there an app that can change cpu speeds based on what app is on the foreground?
my regular usage is:
1200mhz,
ondemand,
3g enabled all time,
~40mins talk time
~100sms
~45mins gaming/video (for train journey =D)
~5mins gps (to check for my bus home)
Push exchange emails
auto brightness
haptic feedback
Tablet-Mode
I have tested that for 70% of my daily usage this works fine for me:
500mhz,
lulzactive,
3g enabled all time,
manual exchange mail sync
but in testing games such as temple run i would need max 1ghz
(have yet to test with music yet... 720p video runs fine @ 800mhz and 1080p @ 1ghz)
i have seen there is a way to inject 3g to 2g toggle when screen is off, is there any way to do it without injecting into the zip? or inject directly into rom?
i think then i could run push emails without much problem. then my phone will really be ON DEMAND!
during 500mhz i notice a slight reduction in battery consumption (not as much as i thought however)
i am running D4ROM v10 with siyahkernel 3.1.2 with resurrection remix as dual booted rom. will prob be getting the 1900mah anker battery heard its decent and fits in normal cover, so yes please let me know if you do get longer then a day, and also if what i need is available (i have searched)
There is no need for such applications mate because android by itself handles the load balancing. The load increase/decrease is basically dynamic and hence you cant predict that.
Overriding that will only consume more battery.
well from the last 2 years of using android underclocking has always increased my battery quite a bit... even right now its consuming 2-3%/hr compared to 5/6% from 500mhz and 1200mhz in sleep, at the end it adds up!
I imagine Tasker could achieve your odd request, though I haven't checked.

I have got the tasker 7 day trial and i can honestly say it is amazing! takes android to a whole new level!
got 2g and underclock & screent timeout 20secs when screen off, then when i use dolphin it connects to 3g, when i play games it clocks to 1ghz 10mins screen timeout. when i plug in OTG usb stick it opens mx video player !
only problem i have is when the screen times out it underclocks (say if ive opened a game) then when i wake the device and unlock again, - the profile says it should clock to 1ghz... but it is staying at 800mhz (which is the screen off max clock speed...) - temporarily just pressing home going to recent apps and opening the game again
p.s. using around 2-3% on sleep/hr and 4-5%/hr with moderate usage (few texts, browsing, play store)
I have not used my phone at all. 0 use.
4 hours 45 mins and 6% is down.
I tell you, not even a text message. Charged it over night and haven't touched it.
is there a way to find out what's draining my battery?
I just had the Mytouch 4G... it stayed in 100% for hours if I didn't use it.
Few questions:
1. Were you in a weak signal area?
2. Did you have background data toggled?
3. Is the phone actually asleep?
4. Do you have any apps that do b/g sync(twitt, fb, g+, etc)?
3b. https://play.google.com/store/apps/details?id=com.bvalosek.cpuspy&hl=en
^Dl that app and check the CPU levels while idle, it's possible that a rogue app is preventing deep sleep, or that the CPU freq is remaining at high levels--even during screen off.

1. Thanks Ace... I live in Miami, so the signal is perfect.
2. During this off time, I had sync and data disabled. no data, just text messages coming through [none received though]
3. I'm not sure if the phone is actually asleep. I assumed it was, i didn't touch it once for the 4 hours that it was unplugged.
4. No Facebook app, Twitter app yes. Google+ yes, but like I said, data was off.
3b. I'll download that app and give it a try, thanks!

Yeah I forgot to mention the Cpu spy app before so I made it 3b. After you try out the app if you notice that the device spends a significant amount of time at high frequencies, then that is one possible explanation for your idle battery loss. If your phone is rooted then you will be able to force lower clocks via the profile management in SetCPU; however if you are not rooted there is not much you can do, but endure the battery drain and hope an update will fix it up.
At that rate you'd get 79.2 hours on a single charge. There's nothing wrong.
You also have to remember that these phones dont really charge up to 100%. Its really at about 98-96% so it doesn't overcharge the battery and will make the battery have a long life.
Yeah if you think there is something wrong you must be coming from an iphone.

My Galaxy S3 Battery Life Sucks Please Help! 15% After Only 7 Hours.
I’ve been having this same problem sense I got my phone about 2 months ago but now I’m finally just tired of it! My phone is rooted, using the stock ROM.
What I do to help battery life:
- Every morning I hold the home button and kill multitasking and kill all running aps in the background then I open autokill which automatically kills running apps in the background that are not needed.
- I have power saving enabled
- Easy Battery Saver running
After 7 hours of use I’m already at 15% and through out the day I barley use my phone. Its like this just about everyday. I use my phone about an hour of the entire day of web surfing and Facebook usage etc. The rest of the day I’m only texting and maybe taking 3 or 4 phone calls that last 10 mins. How much battery could that possibly take? A flip phone can do that and last 3 days..
I used my iPhone 4S much more during the day then I do the galaxy S3 because the S3 has terrible battery life.
On my iPhone I would have about 22% after everyday of using it for 11 hours down time = sleep and 4 hours of usage = texting, , phone calls, web surfing, games etc.
I don’t play games or watch movies on my S3. Only texting, instagram, facebook, websurfing which is about an hour a day usage. Also a couple minutes of GPS usage on some days.
What can I do to fix this? I don’t want a bigger battery that will make my phone any thicker.
I have pictures below showing usage through out the day and usage under battery.
Please help!
Thanks!

Oh thats easy.
You're phone is always "Awake". It doesn't go into Deep sleep like everyone elses. If you take a look at the first picture you linked with the graph, it shows that the phone is always AWAKE.
For comparison, I have attached mine as a reference but something is DEFINITELY keeping your phone awake.

Can't really see anything that stands out per say...
If you see anything on that thread or any apps on your phone that you think could be keeping it awake, just uninstall them. I would suggest trying to remove them a few at a time just to narrow down which ones are keeping the phone awake.
Also, apparently this app helps a lot (https://play.google.com/store/apps/details?id=com.bvalosek.cpuspy) and Better Battery stats should give you a better idea of which apps use the CPU while your phone is trying to sleep.
Oh and remove any task managers you have installed.. Those tend to be the worst offenders.
One last thing, found this on another forum:
- Don't use an automatic task killer--not even the one that comes with the phone. Reboot your phone and look at what's running. If anything that you've installed is running and there's no reason for it, then uninstall it and find an alternative that behaves. Ignore any stock apps that run on boot as I've found them to be more or less benign.
- Weather widgets, live wallpapers, news/social feeds, any app or service that you use that runs--do without it if you can. If you can’t do without it, lengthen it’s refresh time.
- Don't use antivirus
- Set your WIFI sleep policy to never. The default is "turn off when screen turns off". This will cause the wifi to reconnect every time you open the phone. From any Home Screen select Menu/Settings/Wireless & Networks/ and then use the Menu button to see some new options - select Advanced. Then select Wifi Sleep Policy and set it to Never. Home key to return to Home Screen.
- If you have access to wifi, leave it toggled on as it is more efficient than 3G. Wifi consumes less battery power than 3G.
- I leave GPS toggled on too by the way. Apps use it as needed. When I'm done with Maps or an app that uses it, I'm sure to return to the home screen so GPS can stop. Under wireless settings turn on "Google location services" so that an app is able to use network resources to get your location instead of GPS. I have "VZW location services" turned off--don't know why that option is even there. By the way, I increase the speed of voice output > text to speech > speech rate because I like the directions to get spit out faster. That saves a bit of battery. Turning off the display and just listening for directions help. Also, often I just get the directions and then exit back to the home screen: GPS uses so much battery I try to get it over with ASAP.
- Under Accounts, click on any account listed and turn off sync for any items that you're not interested in syncing. For example, Google Books if you don't use it. Don't use Backup Assistant--I prefer syncing my contacts with Google. You don't need both. Also go into your contacts > menu > display options > backup assistant > UNCHECK. Also do contacts > menu > more > settings > contact storage > and select your Google account and "remember this choice"
Are you on the 3G network a lot or weak signal areas? Is your phone hot around the bottom? If yes to both, most likely it's because of the system attempting to find a better signal. When I was swapping out my SIMs, in various countries, I only have 3G network and my battery fully drains in 7hrs at idle. The only way i can go a whole day is to place my phone into airplane mode or wifi only to conserve the battery.
my battery runs at-most 13 hrs........................

My Galaxy S3 Battery Life Sucks Please Help! 15% After Only 7 Hours.
I’ve been having this same problem sense I got my phone about 2 months ago but now I’m finally just tired of it! My phone is rooted, using the stock ROM.
What I do to help battery life:
- Every morning I hold the home button and kill multitasking and kill all running aps in the background then I open autokill which automatically kills running apps in the background that are not needed.
- I have power saving enabled
- Easy Battery Saver running
After 7 hours of use I’m already at 15% and through out the day I barley use my phone. Its like this just about everyday. I use my phone about an hour of the entire day of web surfing and Facebook usage etc. The rest of the day I’m only texting and maybe taking 3 or 4 phone calls that last 10 mins. How much battery could that possibly take? A flip phone can do that and last 3 days..
I used my iPhone 4S much more during the day then I do the galaxy S3 because the S3 has terrible battery life.
On my iPhone I would have about 22% after everyday of using it for 11 hours down time = sleep and 4 hours of usage = texting, , phone calls, web surfing, games etc.
I don’t play games or watch movies on my S3. Only texting, instagram, facebook, websurfing which is about an hour a day usage. Also a couple minutes of GPS usage on some days.
What can I do to fix this? I don’t want a bigger battery that will make my phone any thicker.
I have pictures below showing usage through out the day and usage under battery.
Please help!
Thanks!

Welcome to smartphones. The calls alone will drain the battery. Seven hours isn't horrible for all that. It isn't a flip phone.
why your phone is always awaking?

maybe you have to flash a new rom
If you want, you could try to flash a custom ROM. I had the same problem that you have, and I flashed Revolutionary S5, and now my phone lasts minimum two days with the same usage, maybe a bit more.
Too bad Tony Stark hasn't gotten involved

Titanium Backup will assist a little bit. When you do a backup of an apk it will tell you if the application is running. You can find all kinds of sneaky apps this way. Many of them were ones I didn't use and didn't really want. That will probably yield minimal results, though. Keeping a black background helps on my S3. Colors, widgets, and live backgrounds will drain the battery. Turn off the menu and back key lights. You know the buttons are there. Turn off all haptic feedback and key press sounds. Of course, try to lower the screen brightness. Leaving my data and sync on hasn't caused me any problems, but you will save some battery by turning them off when not in use. I also read a post about hidden menu options that ran even when they weren't meant to. That was an issue that destroyed battery life. Some ROMs also have settings for data connection type. You'll save power by telling your phone to not worry about gaining signals like 4g, 3g, etc. As other people have said, try out some ROMs that make battery life a big priority.
it CAN get better
if you want to have a good battery life, use custom rom and kernel (or a modified stock like omega rom), watch out for wakelocks + apply these settings:
