SGS2 Battery problem.

---

Dear XDA people,

I got some problems with my SGS2, when I charge my battery, when its on 50%, it gives the message Fully charged and it shows that I got 100% battery, but actually I got only 50% Battery... I had this problem with the stock rom, but Flashed a new rom checkrom. Still the same problem and the Battery calibration app isnt working. Even if I wipe battery data, it still gives the same problems.

Got any ideas how to fix this problem?

Thx in advance,

Yes, a new battery. It sounds defect

Defective battery. If it's within 3 months/90 days I imagine they'd replace it for you, if not you'll need to buy a new battery.

Nah, thats not the problem since I have a 2nd battery.. Its a software problem I guess but I cant figure it out.. really sucks

First step backup data and factory reset .

Second step install stock rom and test .

Fails then reset rom counter to zero and return under warranty .

Did a factory reset still the same problem.
Probably a hardware problem
