[Galaxy S II Q&A, Help & Troubleshooting] BrandoHD:
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
[Galaxy S II Q&A, Help & Troubleshooting] StevenBX:
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!
[Galaxy S II Q&A, Help & Troubleshooting] chalid:
I'm using stock KH3 with a stock kernel and am perfectly happy with the battery life ...

Im also a noob just got phone. Coming from evo, how do I root,
[Galaxy S II Q&A, Help & Troubleshooting] poch_1421:
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 :)
[Galaxy S II Q&A, Help & Troubleshooting] biffsmash:
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 :)
[Galaxy S II Q&A, Help & Troubleshooting] StevenBX:
I used this guide to install the latest firmware, and this guide to root it when I was done.

[Galaxy S II Q&A, Help & Troubleshooting] veyka:
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.

Which ones provide the best battery life?

It's not very helpful if you don't direct this poor guy in any direction.

[Galaxy S II Q&A, Help & Troubleshooting] gokhanmoral:
Use touch x-power 1.0

It is optimized for battery life
[Galaxy S II Q&A, Help & Troubleshooting] lynzoid:
stop the madness.... just disable Gtalk autologin and you'll have x3 batt life....

i'm still on KG2 and see no need to update, as i easily get 2d+ battery life now...

EDIT: oh, and custom roms is for nerds. that's it. stock only.
[Galaxy S II Q&A, Help & Troubleshooting] TECK:
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.
[Galaxy S II Q&A, Help & Troubleshooting] htc9420:
Best opinion so far...all true. Beside AOS, Gtalk is the next issue whet it comes to battery life. Also, the stock Roms are quite smooth since July, never had any issues so far...
[Galaxy S II Q&A, Help & Troubleshooting] poch_1421:
if you check the threads of the different custom roms, they will actually almost always say that theirs is built for an optimized batt life.

the best thing i think is to read their threads just try them out. of course different people will have different results :D

i tried about 4 customs roms. and i settled with the one i'm currently using :)
[Galaxy S II Q&A, Help & Troubleshooting] xZeDgEx:
Say what? There are a pretty small number of users who root or use custom roms .. probably 99% of people would have no idea about this. Sorry I just found your comment rather rediculous.
[Galaxy S II Q&A, Help & Troubleshooting] poch_1421:
sorry about that. it's just that almost all i see in the forums are using custom roms.
[Galaxy S II Q&A, Help & Troubleshooting] JJEgan:
From experience the first step is to sort your apps out that are using unneeded power or connecting for no reason .

Look for an overnight sleep drain of 2% by fully charging phone wipe battery stats .

Turn off wifi data GPS bluetooth and twelve hours latter open Better Battery stats and see the partial wake locks for any excess usage .

Highest on mine this am is 5 seconds with a 4% drain in eleven hours . Once you have sleep/stanby down to a low drain you can work your way through normal settings .

Then try a custom rom if you want .

I get two and a half days on light use less on heavier use .

jje
[Galaxy S II Q&A, Help & Troubleshooting] StevenBX:
I had my phone on aeroplane mode overnight and it drained 2% overnight, which I think is pretty much comparable to the test you suggested (only difference being that you suggested turning only data off instead of GSM service too, but I don't think that'd make much difference). I have a few partial wakelocks over 1m this morning (although I have been using the phone a little before this, so probably nothing to be worried about - *network-location* at 1m25s and DhcpHandler at 1m1s).

I seem to have sleep/standby settings pretty much sorted then, from what I can see - now it's quite obvious that it really is that giant screen sucking the juice out of the battery every time it's on for even short periods of time!

If I flash custom ROMs through CWM does that mean I lose all my settings/widgets/apps/APN etc everytime I flash? I'm a bit reluctant to flash ROMs as when I flashed the stock 2.3.4 I lost all that stuff. I had a backup but still took a while to sort out the widgets and settings just how I liked them. And how easy is it to go back to EXACTLY how things were before if I don't like the ROM - i.e. same widgets/settings/etc?
[Galaxy S II Q&A, Help & Troubleshooting] JJEgan:

Not if its a no Wipe rom yes if its a wipe rom .

[Galaxy S II Q&A, Help & Troubleshooting] mredfern79:
I found the same with the battery when i first got the galaxy S2 in june. I tried some of the things you mention but found just doing the following really made a big difference. Instead of relying on apps to fix the problem.

The Galaxy S2 already has its own task killer. As I understand it is worth noting it can use more battery and time to load apps than leave idle in the ram.

Latitude in my experience is one of the biggest battery drains. 20% + battery drain overnight with it on 4% drain with it off.

All those auto updating widgets samsung provides are probably another battery killer. If i never use or rearly use them i turn them off. The weather widget i have update only when i turn on the screen. No point it updating several times if the screens off. I use beautiful widgets for this.

Facebook and twitter i set to manually update. Ive gone 3 days between charges on low use, i was in the countryside with almost no signal and couldn't use it even if i wanted. Lol. Most nights i have 4% battery drain overnight with wifi on. I can go 24 hours between charges with game playing and 2-3 hours of movies. Some txting, facebook and calls.

Undervolting the cpu really helped increase battery during use. Obviously you'll need to route your phone and install an appropriate kernel to do this.

Hope this makes sense if not just ask and I'll try to explain further.

[Galaxy S II Q&A, Help & Troubleshooting] TECK:
Remove all the crazy apps and disable Latitude, Gtalk, etc. when you don't need it, then you will get even a better battery life. Heh, Juice Defender makes you think you save battery but the app itself consumes MORE than it saves. I use the XXKH3 stock firmware.
[Galaxy S II Q&A, Help & Troubleshooting] dehugin:
i agree all the the battery saving apps are crap, best to find the problems and destroy them with a hummer fist! and later a fist pump

Have tried all the kernels on here, and am happy to say the battery life is pretty crap, on the sgs2
[Galaxy S II Q&A, Help & Troubleshooting] StevenBX:
Managed to get 0% battery drain overnight last night on aeroplane mode with a max 21s partial wakelock, so I think I've got everything sorted now. With GPS, WiFi and 3G on and my phone sitting on my desk at work I'm losing about 2% battery an hour, which doesn't seem too bad. I guess with moderate use (i.e. checking Facebook/Twitter at lunch and on the train home) and being on aeroplane mode overnight that makes up to 2 days light-moderate use.

Since having all radios on for 3 hours this morning, the only significant partial wakelock I have is Friendcaster Pro with 21m+, which seems excessive given I have it set to check for notifications only once per hour. I may experiment with turning that off and seeing if the official Facebook app has less partial wakelocks.

I may also install RageMod kernel instead of SpeedMod to tinker with undervolting over the next couple of days.

Apols to all of those bemoaning a new battery life thread - for those of us new to Android, these forums are a little overwhelming at first and even the stickies don't do a great job (IMO) of suggesting really worthwhile mods like some of the posters who've replied here have - my thanks again to all of you!
[Galaxy S II Q&A, Help & Troubleshooting] DreamWiva:
Ohh thanks mate,

I was confused at first with what that thread actually was, I thought it was a list of firmware for people to flash back to the original states on their phone, turns out I was a bit silly lol
[Galaxy S II Q&A, Help & Troubleshooting] superleeds27:
Is it true that Juicedefender uses more then it consumes?

Ive always used this app, Im currently getting just short of 2 days battery with average use.
[Galaxy S II Q&A, Help & Troubleshooting] lotacus:
The phone has excellent battery life. Stop playing around with it and you will see. Remember, the primary feature of the device is a phone. it urks me always seeing people complain about poor battery life, when the direct cause are their habits. People are always too quick to blame the device.

The more often you use the secondary features the faster the battery will drain. It's a no brainer.

Stop freak'n complaining or get a feature phone.
[Galaxy S II Q&A, Help & Troubleshooting] rinnego:
I was also surprised at first at the battery life , but I knew I was doing things wrong somewhere , just try to give a shot at every possible tips out there on XDA .

For example brightness , adjust frequencies of your cpu via SetCpu ( especially the one while the screen is off ) trying playing with voltages but you have to be careful with those settings .

Freez apps via titanium if you got it , and disable all that is unaccessary ( Samsung apps for example ^^ )

And calibrate your battery after all new ROM flash .

You should be good then .

I got easily 2 days out of my device , but I must say I'm not a heavy user , just medium .

Hope it helps
[Galaxy S II Q&A, Help & Troubleshooting] StevenBX:
Just got home from work and still have 76% battery, which I'm pretty happy with. Took it off aeroplane mode (after being on it all night, after having been charged to 100%) at 8am and it's now 6pm. I guess it'll go back on aeroplane mode again at about 10pm 'til 11pm, so I reckon I'll still have about 60-65% at bedtime, which implies more or less a 3 day normal use life, which I'm really pleased with!

The tweaks everyone's suggested seem to have worked out really well!
[Galaxy S II Q&A, Help & Troubleshooting] dragon546:
Hey Steve once you calibrated your battery you will see some more differences. I am using a custom Rom and just doing a battery Calibration halfway through it and I am on 11% after being off charge for 1day 20hrs and I am running everything full tilt to drain the battery so I can complete my calibration.

I expect as the poster above to get around 2 days worth.

Can anyone help me resolve this issue please?

I get stuck at the Sony Ericsson logo but it responds to nothing at all. When I say nothing, I mean NOTHING. I think this is an unusual variation of a full brick.

I've searched through many many threads for answers to this. I've tried alot of different things such as SEUS, Sony Ericsson PC Companion and even the latest version of the Flash Tool. Xrecovery does not load but it was in the middle of backing up a rom when the phone switched off.

I am using Flash Tool 0.3.0.0 with the Sony Ericsson X10i_2.1.A.435_GLOBAL-GGL GENERIC 1232-9897. I followed the instructions to the letter, but I am told to turn on Unknown Sources and Debugging which is impossible from being stuck at the splash screen. I've tried it on a different computer to no avail, without SEUS or PC Companion as I read the drivers conflict with the GG ones.

p.s. I've also tried Flash Tool 0.2.9.1.

Thank you in advanced for any help you can offer me.

Thank you for the quick response.

I am using the X8 and therefore it does make sense to use an X8 Rom, I was rushing and made the mistake. I've downloaded the X8_Shakira_E15i_2.1.1.A.0.6_generic.ftf and placed it in the firmwares folder of the 0.3.0.0 Flash Tool. When I click flash, it does not appear in the list though?

You're very appreciated for the help.

Hi,

I just bought a new Iconia A501. To connect to the customs company's APN, I have to create a new APN profile. Within the profile, I have to enter DNS-settings manually. But I can't find a possibility to edit these settings.

Can this be done with an APP ? Or do I have to 'root' my device. Are there How-to's available to do this ?

Thanks for your help.

Try this, it's an APN shortcut program that opens up your APN settings. I installed it on my tab just to make sure it worked first.
