Hi guys, I've been reading the forum for a while, and now I'm here to ask for your help.
I root my PRS T1 when the battery was charged at 70% and it last like a week to discharged, with almost an hour of reading, lots of dictionary searches in Coolreader and the wifi turn off. Is it an average duration? Do I need to recalibrate my battery following this procedure

Thank you very much.
