Device: Lenovo Vibe C Android: Lollipop 5.1.1
So now after a reflash I tried to root my phone again by the KingRoot app. It went fine upto 24% when I thought of disconnecting the router which it was connected to. The app showed me that a file could not be downloaded and then as it happens (on this device particularly during rooting, the phone shut down). Usually in such cases I remove the battery and reinsert it and boot the phone to continue with the root procedure but this time it did not happen. I tried twice but failed. It was after that I removed the battery for about 30s that it booted up again. After the boot the battery indicator in status bar was working in a strange manner. It first showed 50% then the next instant dropped to 2%, and remained there for about 1 hour. Then after I plugged the charger it again jumped back to 50%. In spite of this I charged the phone for rest of the evening. When I again started using it some minutes back, it started behaving strangely again. Initially the charge was 88% then it jumped down to 50% then to 69% and so on. Here are some statistical screen shots taken from 3C Toolbox.
My device is 2 years old so there are no issues with the battery itself I think it is the OS files that are causing the disturbance. I think this would be a silly question (as it is not possible) Did this happen due to the kingRoot app? What may be the cause, please help me out.
The battery files of the OS, I think these (the current_now and the temp_cool ones) probably have been corrupted in some way. Can they be replaced with files downloaded from the internet(if any). Please help
