I'm a new Galaxy S II (and new Android) user, and am a bit disappointed in the battery life of my new phone. It was running down extremely quickly yesterday, only lasting about 12 hours with relatively normal use (sending half a dozen texts, downloading 2 apps, checking Facebook and Twitter once an hour or so for a couple of minutes throughout the day). I allowed the phone to discharge completely and charged it fully last night, but this morning nothing seems to have improved. I burned up 10% of the battery in half an hour sending 2 texts, checking my emails, Facebook and Twitter and downloading and trying out a couple of apps.
I'm anxious to know if there's a bit of a burn-in time with the battery on this thing - does it get better after a few charges? I see a lot of people saying they can have the phone on for a few days in some cases, but that's definitely not my experience thus far.
I've installed JuiceDefender (balanced profile), AutoKiller Memory and Advanced Task Killer to try to sort things out but none of them seem to having too much effect and to be quite honest I'd rather not have to compromise my experience by running a number of apps like this to try to extend my battery life at all (nor do I want to have to turn the brightness right down to an unusable level, or set black wallpapers for example).
Does anyone have any real advice on this? I'm starting to think that switching ROMs might be worthwhile? I see that the leaked 2.3.4 ROM seems to have better battery life - is this correct? I'm a bit reluctant to switch to any other unofficial ROMs as there are so many I wouldn't know where to start. It seems they all make a lot of changes but I'd want to keep as close to the stock feel as possible, just with better battery life.
no one uses stock roms/kernels nowadays. u should flash a custom rom or kernel since they provided optimizations to batt life.

It is argued that task killers and memory killers will only make the problem worse. Juice Defender might be useful if you are using it for scheduling sync and turning WI-FI off when the screen is off, but this feature is only present in the Ultimate edition and you can turn off sync and WI-FI manually if you want. Also beware of rogue apps which are syncing all the time. It is normally the main reason of poor battery life.
Other reason, is that whereas powerful tech specs for phones were rapidly developed, battery technology didn't followed the pace. Our simply batteries cannot cope with our beasts.
Also, there is a thing that it's called "new phone battery blues" which is described as poor battery life due to excessive use of a new powerful toy. After you use your phone normally, for the purposes that normally people use a phone, your battery life will became better.
That said, personally I have a spare battery and a spare charger, and when the battery being used is low, I replace it with the charged one. Sometimes it is necessary, sometimes not.

They also have a tendency to look very tacky I think though. I think Samsung's skin and widgets are pretty nice and don't care too much for the mods I see in the screens of most ROMs. I'm really looking for something very similar to stock, except with better battery life if there are any suggestions? That's why I was thinking of just jumping to the leaked 2.3.4 if it had any noticeable impact on battery life...
Try using better battery stats, link in my sig, to see if you have any wakelocks, the thread has a good howto on using it.
The biggest thing that uses the battery on this phone is the screen, you will get between 4 and 6 hours of screen on time depending on usage and screen brightness.

Get the original samsung 2000mah extended battery kit.
ahh the battery life talk again
brings back memories of the first days of the SGS2
never thought of reading one again

Fair point - not all of the roms are everyone's cup of tea. My advice, as a starting point is to flash the stock XXKH3 variant for your area, and then flash a custom kernel, such as Ninphetamine's or Hardcore's Speedmod. This will greatly help with battery life, and also give you the ability (via root access) to use Titanium Backup to freeze apps and services you're not using, which is often the major cause of battery drain through 'wakelocks'; apps that prevent your phone from entering Deep Sleep, or continuously wake it up.
Update to the latest version in your area, uninstall those task killers and whatnot or do a factory reset, install the apps that you are going to use normally like facebook twitter and install better battery stats, decrease brightness to your most tolerable level.
use the phone normally and when the battery is low, use the tool provided in android to check if your phone is sleeping when the screen is OFF, if you are having wakelocks, then use better battery stats to find which apps are causing the wake locks.
No need to install battery management apps, or task killers or memory optimization apps (or as custom rom as yet), that would only compound you problem which may be a very small one to begin with
Thanks for the help so far guys. I've installed XXKH3 and flashed hardcore's Speedmod kernel, and am just getting things set back up the way I like them again. I'm going to uninstall the battery saving apps for now and see how the battery lasts the next couple days.
I'll install Better Battery Stats and keep an eye on any wakelocks too.
Thanks for pointing me in the right direction - it was all very simple and quick to get set up; the sheer number of kernels, ROMs, etc. is all a little overwhelming to me right now, being new to Android!

there are other tweaks with custom roms that aren't found in the stock rom (which provides better functionality).
btw, i also suggest u use setcpu to underclock your device to save more batt.

wow, good for you
I used HTC Desire before this device, and the roms on there actually hindered battery life, even with all the fancy underclocking, so I am betting, without even attempting to brick my phone, that they are just as overhyped on this phone too.
I get two to three days out of my phone, using it as a PHONE. I can send and receive emails and texts all day, along with phone calls and the occasional browsing and still get at least two days before it dies. I turn off data when I dont want it and stick it in 2G mode and it dares me to kill the battery.
Just let usage settle down and it's fine

Beware using anything that isnt ondemand on samsung phones, can cause stuttering, that's what I found anyway.
As far as undervolting -25 to -50mv is a safe first bet.

That is wrong. I used to have a UGKG2 ROM and since I upgraded to XXKH3, the battery is MUCH better while the GPS pinpoints in less than 3 seconds with a 5meters accuracy.
Hi,
Does anyone have any kind of summary of the available kernel options for the SGS2?
I've been running mostly stock firmware, though
a) using the cf-root kernel (for titanium backup and wifi adhoc)
b) Updating via odin & using frankenstein firmware
For now I'm planning to stick with the stock rom as performance and battery life is good, as is software compatability - no messing, most things work.
Though I am intrigued by the other kernels that are floating around especially with respect to power saving. Compatability/currency is critical - other features are secondary. This includes gpu acceleration and the likes all working properly.
I mostly leave some sync active along with push apps so ridiculous standby, but only with all comms down isn't interesting. I don't have a power issue though as can get 12-17 hours usage on stock.
I like the idea of BLN but worry it's going to hit power too much due to wakeups. Just maybe it might be handy if it can be figured for infrequent notification
Are there a particular subset of kernels worth looking at? Trying to cut down the problem space for all of the kernels.
Someone mentioned "siyah" as a good one?
I'm on KI8 now, probably moving to KJ2. root is a given?
Or maybe I'm too conservative - are there current, close to stock roms that I'm silly in ignoring?

Not being funny mate but by the time you wait for someone to reply to you, you can actually take the time and search first in this forum to see if anyone else has answered your question....Loads of threads around to see which kernel is the best...Or even actually take the time to go into the Original dev section and read about each kernel that is available there....so next time before you open a thread please press the nice search button and read
anyway go for either 3 tops kernels ninp, speedmod or siyah..
The amount of info seemed overwhelming.
I ended up going with speedmod 2-12
Siyah was also on my shortlist

Use your phone less and/or plug it in.
P.S. If you think this is a vague response, I think your request for help was vague. When you go to the doctor and tell him/her you have a pain, what happens next?

totally agree with ZACQ8
You can get a 2450mah battery that doesnt need a different case. Also try Android Assistant, you can view processes that are running and sort by cpu usage. Try to remove or atleast kill from startup any apps that do not need to run all the time. Most battery assistant programs do not work as after killing an app it will just load back up a few minutes later.
I got the official 2000 mAh battery which did give 15% more life. However the most effective improvement I got was from using the SpeedMod kernel and using Tasker to be more precise about when things came on.
Went from around 14 hrs stock to 30+ hrs for SpeedMod on stock rom for GB.

Hi,
To avoid too fast draining, some classics advices are to turn off some functionalities when you not need it, by example Auto Sync. Many applications needs to be configured with less frequent synchronization (weather apps or widgets, email apps, news apps...)
And as it was mentionned, some kernels can dramatically improve your experience. I agree that Speedmod is one of the best kernel to preserve battery. You can flash it easilly via CWM.

Hello People,
As you can see im new to this community, i hope i won´t bother you so much.
I got an S3 myselft and unlocked it right away before even using it. Did use Samsung S3 Toolkit , which i think its a great tool and this forum is a huge palace full of incredible geniuses so i´m really grateful for what is has done for me already.
As i stated in the title i´ve been getting serious problems after rooting my phone , everything working fine. or i think it is. But the UI in general became slow as hell , it crawls on the floor , pressing the menu butom to go back takes from 5 to 8 seconds to respond onto something , no matter what , oppening applications is not that slow but switching pages or screens is LAGGY as hell. I tried full wipe , cache wipe , before and after flashing.
Actually using this rom I9300UBEMA1_I9300UVOELL1_ARO its the Non branded version of my Local Firmwar (Argentina) , the kernel i use if the one that comes with Samsung S3 toolkit 7.0.0 the 4.1.2 unrooted version for JZ054K.ELLA ( file name :boot-insecure-ella-GTI9300 )
The original Firm and kernel the phone had was the 4.0.4 "Personal" Branded BLG6 Kernel.
I know this phone is already known as a battery killer , but i didn´t spected to be that kind of slow to crawl device. I´ve already tried multiple task killer apps like AutoKill or ES task manager , Better battery stats to check battery drain but still cannot find a reason. Tried Juice Defender Ultimate on Extreme settings. And did nothing to my battery life.
Then Looking for some Customized roms i found out 2 that took my attention :
One of them is Omega and the other is Android Revolution HD, which one of these are going to have a possitive effect on performance gain + battery economy without overkilling phone capabilities ? . Is that the answer? or are there any real app / patch that could really resolve this issue.
Well people im sorry if this question sounds quite stupid or bothers some people but i already researched more than 200+ hours and i couldn´t find the exact point where i should be heading to solve this.
I would start with a fairly,near to stock Rom, I won't suggest any, just go to development and read up on the Roms, but also try a custom kernel.
Don't use task killers, they are counter productive if not used right.
I would also suggest going through what you have enabled, the smart features can heavily affect battery, also poor signal, and it might well be you need to check your modem (baseband) and see if there are other more suitable ones.
Keep reading and searching and you will develop a good understanding of various ways to make this phone fly, just don't rush things.
And, backup, backup, backup! Enjoy
Better Battery Stats and Greenify from the market may help .

He's right, try flashing a more popular widely used stock firmware like the XXELLA rom or the recently released ones. Also do post screenshots of BetterBatteryStats.. Kernel wakelocks are major reasons why battery drains. Often IM+Social Media apps use network data in the background and are culprits behind wakelocks.
I for one can confirm the Facebook native app as being a major contributor to the problem.
You should also check if "Fast Dormancy" is supported by your carrier or not? FD is by default enabled on the S3, disabling can save substantial amount of battery life. You can do so by downloading "Fast Dormancy Toggle App" from PlayStore.
As for custom roms, it really depends on user experience. I have used Omega rom and it easily lasted a day and half for me with good usage.
Currently I'm running CyanogenMod 10.1 and it lasts me 2 days
post betterbatterystats screen
Try custom roms
at first: this is not a "whats the best rom" thread.
i have 2 very focused questions:
What are the idle times with those different roms?
Are there some Main feature differences?
Aktually im running cm11 m5 snapshot with smartassv2 Governor. its smooth but the battery life is kinda poor.
Im looking for a rom with long battery life. And i dont care about google now, talking to my phone(ok google) nor i need the special features from the standart samsung rom.
Would be realy helpfull if u can review to my questions. Greetings!
pls apologize my bad english.
1 each phone is different depending on what's installed and running.
2 read there threads or flash each ROM and find out that way. You forgot about aokp?

There are no definitive results, I have used both and I keep coming back to Omni due to the fact that on SlimKat music stutters like crazy when the screen is locked. Also, Omni updates are small enough to update often without having to download a complete update, to many users this a huge deal due to data limitations in certain countries. As for usage, idle time etc, like stated before, that depends entirely on what is installed on your device. Install a bunch of apps that need to constantly receive data updates and you will have battery drain and very little deep sleep. Where features are concerned, you kinda learn to live with limitations due to missing features on a specific rom. If you really want, you can most likely find an app that will bring a missing feature to a rom. I see a lot of people throwing their toys out the cot because one of the other does not have a specific feature implimented, yet the developers have done so with good reason, usually either performance or battery life.
With all said, there are many roms out there, Omni and SlimKat aren't the only players. It's difficult to compare roms nowadays because you are never quite sure if your kernel tweaking or custom kernel with it's hundreds of tweaks is the reason for a device not going into deep sleep either.
Give them all a try and decide for yourself, nandroid backups and apps like Titanium Backup makes it so easy.

im missing only 1 thing. if someone flashes all roms, doesnt install any apps. Only new rom and full wipe before, restart and tracks the time the phone has battery. Dont u think this is a possibility to compare the roms battery usage? i think there is no one who does this, but i probably will try this and put down a little table here. so people like me are able to see the rom with the best battery efficiency. so if they decide this rom has not enough performance, they can switch to "battery efficiency Number 2" and so on.

Sure you can do what you stated but bear in mind how will you compare the battery life across roms..
There should be some standardized test... Like looping video playback or some other method which does not change based on you usage habits..

Pa is another you're missing from you're list of developed roms. What you could do is test video playback, calls incoming/outgoing,one game of choice "high end battery draining game" and compere them all. As for the kernel tuning.. Read about what really happens and you will fine not a lot does happen with UV/uc .

You can compare but you have to use that phone for more days not like just one and you have to full charge and then discharge 2 or 3 times till the phone make the correct battery stats. So i think you can test but better with daily use or get an app that drains battey faster well i think this may work
