Overcharging the battery?

[916x10]

Is it possible to overcharge the battery? I ask because when I first got the phone and fully charged it, it would stay on 100% for at least a couple hours (using circle battery widget which reads in increments of 1%) but one night I fell asleep with it plugged into the charger and when I got up it still read 100% but as soon as I unplugged it it went immediately to 99%. I have not yet been able to get it to read 100% unless its connected to the charger. Think I could get the batt replaced under warranty since its only 2-3 weeks old?

Interesting article about Li Ion batteries (which we have in our Atrix2's) that I found. It contains info about your question, plus a lot more!

Good luck!

let the battery drain completely
delete /data/system/batstats.bin
reboot
charge it uninterupted to 100%

but, most newer devices will turn off charging when it gets to around 95-98%

Is there anywhere that actually says that it isn't possible to overcharge a li-polymer battery?

The charging of these batteries is controlled by a dedicated chip which automatically control charging on/off along with many other functions like voltage regulation,etc. So no your phone battery cannot be overcharged.
