I have noticed an increase in posts about battery related issues in the past several weeks.

After pulling my remaining hairs trying everything including a reflash and putting no applications on the n810 and when my problems didnt go away I bit the bullet and bought a new battery.
my tablet started having issues when the battery was about 10 months old (or new)

since replacing it with an oem battery purchased on amazon i have not had a single issue. i bought my tablet end of november 2007-

just an idea to pursue....
