Hi I am 15 years old and i have a samsung galaxy s2 GT-I9100 with stock ics 4.0.3 (exactly I9100XXLPS). It have some issues with (not opening some times) wifi and several battery drain when im playing games ( need for speed, asphalt, etc). I want to play games and surfing but my phone does not keep its battery until night. So I want a rom and a kernel which have no much battery drain, fix wifi issue and if its possible to extend the wifi signal...
Sorry for my poor english.
Thanks in advance.
Hi, i'm also 15 yr old, btw i'm from Serbia(if u know where is it...), if u using cf kernel it has a wifi bug so i suggest u to install siyah or dorimanx kernel... And, i think themes like this(whats best rom, which to use, ...) are forbidden, sorry btw try SuperNexus rom, for me that's best rom for begginers, wish u a luck !
I have to say that ROMs are all about personal preference. Imo you should test out various ROMS to see what's best for you...
That being said, I'm currently using Cm7 on my I777 and it has great battery life (although I suspect it has something to do with turning the second core off and using Siyah GB.)
For Jellybean my preferred ROM is Super Nexus... I got pretty good battery on that one too!

I'm using PA 2.54 with Dorimanx 7.17 kernel with moderate UV and battery save settings from STweaks. I deactivate auto-running non-useful apps and location services, use lower brightness, uninstalled some system apps and frozen others, etc. Search forum for more info

Sorry, but i am not a begginer and i know where is serbia... Anyway i am using stock kernel too now. Also i was using latest jelly bean resurection remix with latest siyah a week ago, but latest resurrection remix version had a very big issue with severe battery drain, so i decided to return to stock unbranded 4.0.3 and then try an other rom. Thats why i create this threat, for not trying all s2 roms.....
Thanks to all of you guys who replied.

How many battery cycles did you let the battery settle for? You should give your battery at least 3 cycles before you judge the life of the battery after you flash something. You can also try CPU spy from the play store to see if your device is deep sleeping. Also try better battery stats to see if you have any wakelocks.

I use RR 3.1.2 and I don't think there is a severe battery drain. Use better battery statsto know what caused it, at the first place.

I give the battery 10+ battety cycles in each rom i try before i report... I will try battery stats and set cpu but i think (because i have tried them in rr) they will not give me the exact reason about my problem. I will try again and post here the results.
Anyway, thank you.

In rr 3.0.1 jelly bean (the latest i have tried in rr) i didnt install the fixes which released one day after (was for rom fonts, etc, nothing for battery), because i have updated via update me app, which didnt download the fixes... Yesterday i found these fixes on internet... Do you think that this was a cause of my battery drain problem? But why the problem remained (not like in rr, but ramained) after i installed the official stock 4.0.3?

Hardly when idle and ok while using it. 4 - 5 hrs gaming. That's the max you can get with stock batteries.
Im not 15 and I want a rom and kernel that makes the battery last a week.Will be playing games all day,and making the odd call,and listening to music.
Ive got a ds,a psp and an ipod......but I dont use them now as its my phones responsibility to think its all them........and to make calls etc.
Now why have I got to charge the phone every day ......its totally ridiculous.

Under volt cores to 700-900mhz. Its enough for regular use. Keep brightness levels to 50%. Close all apps. Check and see if Deep sleep works. If not check to see what app is preventing you from getting deep sleep, or ask the kernel Dev if you have a custom kernel. Can you provide us with more information?

Well, my brightness is 0% and I always close my apps, even clearing the ram.
I will try the deep sleep app.
About my custom rom: Disaster Rom included with philz kernel.
I read about a kernel named Hardcore kernel which saves a lote of battery..
Do you know if i can apply it on my phone?
Thanks for the help.

jb leak's got a battery problem?
i don't have a battery problem....some people experience a media scanner issue, which is fixed here:
http://forum.xda-developers.com/showthread.php?t=2012452
the only thing that has drained my battery was wifi, when i was in ICS.
Now with JB leak i went up to 1d 10 hs a couple of days ago.
and philsz kernell would extend it, yes.

using cpu sleeper app from ply store may help...
I think i will change my kernel from philzn to jeboo kernel, my phone was 100%
After visiting xda site for 5mn now 94%
Best solution for battery drain is switch phone off and put in one corner, don't touch at all. What are you want from 4.3 inch display, dual core phone with leaked custom rom? This is not Nokia 3310 to forget when you last time charged. Around xda is lot of guides and threads about this. Just search
Hi,
The battery of my phone keeps on draining like hell since I installed xxlsj leaked firmware. I have tried different kernels and roms but no positive effect. I m currently using dorminax kernel with leaked jb xxlsj.
Please see srceenshot of battery consumption.

Are you close to the router? That pic shows it's far range. Wifi would constantly try to get a better Wifi Connection hence, massive battery drain. I have the same issue when i'm bunkered in my bedroom.
I'm running JB leak as well and battery life is just awesome (see Attachment)
Hello everyone,
I've tried to use the Cyanogen ROMs or any AOSP ROM on my EVO 3D for some time now. I've tried CM 10.2, but I get horrible battery life. Every one of these ROMs seems to have battery drain problem when the phone is not in use. This is always with the stock CM kernel and flashing another kernel, like MiRaGe, seems to help a lot. However, I still get far worse battery life with any AOSP ROM compared to a ROM based on the Sprint stock ROM.
Does anyone have an solutions to this? I'd love to know.

calibrate your battery after u flashed a rom
try formatting sdcard it seems to improve battery life on mine
Vote for greenify hibernating your google content,map,etc,.

No need for Greenify anymore! Use CM 11.. Battery life is awesome.. Some bugs indeed but as I know the developer he will solve this in few releases :fingers-crossed:
i use CM 11.. not bad.. but still alpha release..
as i described phone is slower than my old sgs2.s2 was running smoothly 4.1.2 . even 4.1.2 laggy on my sgs3.now using custom roms but samsung based roms fail for me.is it only my phone or sgs3 fails???my antutu score with s3 21212 on archidroid.
Touchwiz roms are like this due to Samsung. Benchmarks show nth as manufacturers have some cheating methods to make the score higher.

Use other ROM based tw. Its better than stock. Smooth
Battery friendly.?
In my experience 4.1.2 as mg4 was the most stable and fast stock version. After that including 4.1.2 and 4.3 stocks all were laggy and had less battery performance. However, I couldn't find any aosp based custom rom work flawless or at least stable. Each one has its own bugs. Slimkat doesn't support exfat, liquidsmooth was very very laggy and cm has some fc issues etc. As a consequence at least stock one is the stable one.

I was on 4.1.2 since i bought my s3, i decided to try 4.3 and i switched to Android Revolution HD 51 in combination with Boeffla kernel, and i must say performance is way much better and also the battery life, with 4.1 i got somewhere around 4h of screen on time, and with 4.3 i get close to 5h of screen on time, also to mention over the night battery drops only 1% if wifi on and 0% with airplane mode on, preety impressive, you just have to find your way to customize it for daily use

No my wake locks seem normal though there was a suspicious one, I don't remember it's name exactly, but I'll tell when I find it out, only thing I know that it's audio related but I don't think that's it... Other than that battery just melts leaving me with 1-2 hours screen time (on stock 4.1.2) I'll try flash a different rom and I'll tell you what changed
