I've been having a problem for some time now with stock S3 ROM (4.1.2), and now that I've rooted my phone, I noticed it consists with both CM11 and Revolutionary S5. So it's probably the hardware, but if anyone could give me any kind of assistance or direction, I would be grateful.
Here is a recent shot of my battery life: http://imagebin.org/309592
As you can see, I nearly ran out of battery in 2 intervals of charge lasting about 4-5 hours.
If I use my phone moderately, only using like a few apps for 2 hours, it wouldn't last more than 5-6 hours.
If I only use it to respond to texts and get through the day, it lasts for 8-9 hours.
I've tried disabling all of the extra components for as long as I could, use power saving mode on the stock/Revolutionary S5 ROMs, Greenify etc.
Another problem I have is that the bottom part below the battery gets freakishly hot by just using a single app for 15 minutes or so. It's getting to the point where I'm uncomfortable holding it.
Is there any solution to my problems? Should I get a new battery? Or something else?
