had my 7125 plugged in for 2 days straight, and this morning when i unplugged it...the battery instantly went down to 95. 2 mins later its at 91%. WTF is going on? lol
Look on one of the markets for "battery calibrator". Basically it will delete a file on the system then at full power you let the battery run down and it will rebuild the stats for the meter. There are several different ones but they all do the same thing.
If the tablet is brand new, deleting the battery logs won't make much difference... Simply fully charge it and then use it untill it turns off, charge again then use. After a few full charge/discharge cycles it will be more accurate.
