Root [T-Mobile] Battery Drain Problem


I have the T-Mobile Galaxy S 3 just recently Running Cyanogenmod 11 4.2.2 and my battery has the worst drain I have ever seen. Has anyone else experienced this?
Well ive just read on other forum and said to install Gsam to get a battery readout.

also, turn it to airplane mode for couple of hrs (3) & turn it back on.
Worst case, do factory reset
