Battery Issue Kitkat 4.4.4

[Nano1986]

Hello community , I am writing to check the following problem. Recently, about 3 weeks the battery from my phone started acting weird , marking the apparently normal battery but actually was not. First it started with a wakelock of Fastdormancy that produced that could not enter sleep mode. After this I tried reflashing the rom again to see if this was solved and seemed so, but it was not for long, because the battery started dialing a wrong level . This is for example having 80 % and using the screen without stopping between 30 and 40 minutes and was discharged and so follow this matter without an understandable consumption of the battery , all things normal, but it's not what you really have to make . Subsequently i root my cell to see if an app Battery Calibration could fix this problem but it remains a battery which is not consistent with what at first showed me it was 1 day hours aproximadamante . I hope you understand the problem , I used the google translator because it would take too long to write the problem. I have last kitkat version of my carrier company. From the last battery charge it marked 3 days remaining.

Just wondering, have you unlocked the bootloader?

If you already repaired your phone with PCC 

PC Companion (PCC)

Bridge (for Mac)
