Just to be clear, I know the basics about rooting and installing custom ROMs, but I do not know the fine details.
My 10.1 (purchased at launch) first started to experience a bad constant battery drain while in sleep mode when using stock ICS about 3 months ago. Shortly later, MTB wouldn't start up when connected to my PC, even after factory restoration. I rooted it and installed JB 4.1.1 with the 3.1 kernel, but the battery drain continued and I still could not get MTB to start up to transfer files via USB. I tried doing the various battery calibration and reset tricks (fully charge, shutdown for 1 hr, use tab until battery at 40-50%, shutdown for 5 hrs), but the drain continued while on standby. I decided to just deal with it and got into the habit of turning it off when not in use and using Kies Air to transfer files.
Now, the tab thinks it is constantly charging even when it is not plugged into the wall. While on, it will say "charging" on the lock screen and show the charging symbol on the battery. When turned off, it will show the battery icon constantly moving the green charge bar. For this reason, the battery continues to drain even when off.
Any solutions here? I tried factory restoring and using different ROMs (ICS and JB) but I think they used the same kernels? Do you think there is something physically wrong with the battery or the chip that controls the detection of charging and charge levels? Or perhaps the Tab thinks there is a constant USB connection? If it is something physical, any hope of repairs that will not cost close to the value of a new tab?
Any information would be appreciated
Thanks!
