I've been having this issue for a while now and I don't know how this should go on. Before I start, I apologize for bad wording or grammar, as german is my primary language.
I run Android since 3 years now and the problems began to evolve over the last one and a half years. I have it on my two latest devices, my international Samsung Galaxy S2 and my international HTC One X.
On my Galaxy S2, I noticed battery life getting worse and worse. I have my devices usually set up this way:
- All location services permanently turned off unless I need GPS
- Wifi only at home when I need it
- 3G always on
- Brightness about 50%
On my Galaxy S2, I got 2 hours of screen on time regularily. No matter what ROM I was using, if it was stock, CM, or anything else. I thought, maybe I just need a replacement battery. Bought one, changed nothing.
Jumping to my One X. I have set is up similarily to my GS2, running CM11 M8 atm (gonna flash M9 later, to see if it changes anything). It started out the same. I replaced the battery on this one, too, even with a larger one (One X+ battery, 2100 mAh) I only get little over 2 hours of screen on time. I've uploaded some screenshots for you.
Further investigation showed me, that there were no wakelocks draining me, CPU going to deep sleep correctly, no problem. Can anyone tell me what I am doing wrong, or at least that that is normal?! My dad gets days out of his battery, his Galaxy S3 LTE going strong on 40% left after 3 days with 2h 30m screen on. The One V of my mom lasts about a week. A friend of mine has a Galaxy S2 plus (she's a noob in android), wifi always on, location services always on, about 200 apps installed, this thing is slow as hell and it lags itself to death, but she has 10% left after a bit over one day with 3h 40m screen on time. And here I am, not even making it to dinner without giving my phone a good charge up. Right now, 2h 35m into battle, 7m 1s screen on and 94% left. Battery widget reborn says, I lose 1% after 9 minutes on average.
Can this somehow be in connection to my google account? I have trouble explaining it to myself.
Thanks a lot for your help!
