Last year about September I bought Pipo M9 Pro 3g. 3 months ago I upgraded the OS from 4.2.2 to 4.4.2 till now. For the last 1 month I have noticed that the battery is drained somehow and the tablet does not last more that 1 hour open. I have down a battery stats app and I will show you the ScreenShot. What Can I do to fix the battery issue. I wish you can understand something from the pics bellow! Thanks in advance for your help!
It is a good practice that after each new ROM flash to recalibrate your battery. Your 1 hour battery drain sounds like the battery was not calibrated properly and is not normal for M9Pro . If your customs recovery has option to wipe battery stas please do that, if not please use 3rd party apps such as : https://play.google.com/store/apps/details?id=com.nema.batterycalibration

Thank you for your fast reply, I did what you said but I still have the same problem! I have downgrade to 4.2.2 following the instruction on another post and I will check if I will still have the same problem!
Have you been able to arrest battery drain after downgrading to 4.2.2?
