    I'm running CM10.1.3 rom on my Samsung Galaxy S3 LTE. just bought a 4500 MAH Extended Battery and it does not seem to be working as it should. I expected 12+ hours of moderate to heavy usage with continuous screen time. Instead the battery indicator would go from 100 to 80% in an hour and a half of screen time. It seems to last a bit longer if I use WIFI only and not mobile data, however if I'm outside and using mobile data it doesn't hold up as long. I don't know what's going on. Is it because the phone isn't displaying the battery percentage correctly? I have tried to calibrate the battery with Battery Calibration app but it doesn't seem to work. I have Facebook, Dropbox, Viber, Whatsapp, and Twilight app installed and running in the background but even with these processes running, I still was under the impression that an extended battery would not be affected much by them.

    Can anyone offer any ideas as to why my battery life isn't much better under these circumstances?
