Im using Miui 126.96.36.199. It was running good without battery problems on many other theme's, but since i switched to galaxy s theme the battery just drops. It was very sudden to. I was on facebook and had about 50% battery then all of a sudden once i got out of facebook apk. It dropped to 20%. Any ideas why? i mean it didn't happen with any other theme, but this is the only theme i seem to be able to run without random reboots. Also wanted to know what i means when the cpu is lit. When you use the drop down menu.
