[Q] Battery draining too fast

---

I have a problem with my battery I have my new sgs 2 and I rooted and did a new rom and all but my battery is draining really fast under moderate use! 3 hours of moderate use and I lose about 30% battery! What can be the problem? I calibrated and did speedmod kerenel, still heavy drain... in sleep mode I guess it can last like 2 days but I want to use my phone constantly without loosing so much battery

As far as I can tell based on this information, you have no drain. It's normal that the screen consumes power. If you standby time is 2 days, then you have no battery drain.

Lower your screen brightness and avoid using white colours. And no there is nothing else you can do.

But I see slot of people who get 10 hours of use on moderate and even heavy use,.. maybe it's my rom? I use rarity rom with speedmod kernel, maybe I should use checkrom?

No one gets 10 hours with screen on. Thats what you are talking about right? You get 3-4 hours max.

So 30% in 3 hours is normal and not bad.

Right now I got left 58% battery after almost 3 hours of moderate/ heavy use like YouTube mostly fb internet n stuff, is that normal?

I got almost half brightness with 3g always on

Yes .

So is there any particular rom that is known to save battery?

yes, there is a way to save more battery - use common sense.

Srry I meant to write rom but galaxy must have "fixed " it

Whichever ROM makes you not use your phone. Probably best to choose the worst looking one you can find, so you're less likely to use it.
