[QUOTE=Android_808;1153740]ed_boner:
Have you tried looking at the battery output from lshal/ /sys entries. AS has been stated already, batteries deteriorate yada.. yada.. Fully charge the device and find the entries for the design charge and current charge which IIRC are in mWh. If you are still getting the 85% reading, compare it to current/design*100.

tks android..can you teach me how to see this output please?
my batteries are ok..one day they were charging 95% / 97%...next day they both stop at 85%..thats why i find it really strange..
