plugged in charger jumped to full immediately

My Razr completly died and i told the guy in verizon to charge my phone which was completly dead. The battery went to 80% charged after he pluged in 5 seconds.

I believe its getting some kind of false reading. Motorola.. ehh you can send to them for about 7 days.. but I’d rather spend money and get a new phone rather to wait for the died Razr with no any app to come out in a few months.

Every time i plug this annoying phone in it jumps up to high battery... but only if you plug it in when the phone is turned off and charging it will stay at the number on the phone for 1 hour then just jump to 100% and say completed... i believe its getting some kinda of false reading so it stops charging it and perhaps my battery stats file is going wrong.

In order to solev this, I’ve tied to root it and wipe the phones battery stats and calibration files and re write them. I found treads on google and then I began to full charge and drain my Razr four times and it works normally now. 

It seems my phobes software is comunicating with the battery and the charging circuit incorrectly and requires an edit to the battery.
