Hi

I'm new on this forum, have been lurking around before, but i digress.
I just got my SGII 2 days ago, and i'm in love with it (not literally, lol).
So, i already rooted it and today i backed up all my apps with Titanium Backup, and made a ROM backup with CWM.
Now, i find like many other users, that the battery life of JB is very poor on stock 4.2.1.
With WiFi on, and brightness settings on Auto, i lose about 2% in maybe 10-20 minutes.
When i game very shorty for only 5-6 mins i drop from 100% to 96 or 97% (don't know if this is normal or not with Minecraft and Asphalt 8, sometimes GTA 3 and Age of Zombies).
Now, with battery saving on, and brightness on the lowest settings (not auto), the battery life is alot better ofcourse, but still the battery drains pretty quickly when i'm playing a game (losing 3% maybe every 8 mins?).
Is this normal with JB or is there something wrong with my battery?
Also, if it's just the ROM, can you advice me a ROM with good battery life, preferably android 4.4?
Also, i read about Cyanogenmod 11, how is the battery on that ROM?

Thank's in advance!
Sorry if there'are any spelling errors, i'm Dutch

EDIT: sorry, my post was a bit incomplete
Battery resource usages.

Screen: 51%
Android-system 16%
Mobile standby 5%
Media server 3%

Those are some of the apps that eat up battery

3% in 30 to 40 minutes with Wi-Fi on?
I'd recommend you don't change a thing. Consider yourself fortunate because those are good numbers.

Sorry, corrected the post, 30-40 mins was incorrect

Also, another question, when installing a custom ROM, does it matter if it's a T-Mobile version or Vodafone?
Or doesn't that matter as long as its for the i9100?

Carrier specific custom roms ?? Not sure what you mean by that; there's no such thing.

If you mean 'Can I flash a stock rom for a different country or carrier ?', the answer is yes.

I strongly recommend you read the guides/tutorials stickied near the top of General section. This will give you a good grounding in 'the basics'. If you're going to be modding your phone at all, you'd much rather read & learn, rather than learn the hard way & end up with a busted phone.
