MobileRead Forums - View Single Post - Survey: Sony Reader T1 with root and Baterylife

Before rooting, battery should be fully charged.

Just in case you didn't notice: https://wiki.mobileread.com/wiki/PRST..._Recalibration

My T1 lasts 1..3 weeks, but sometimes it drains over night. Not sure why. Rooting itself can't be the cause (well, depending on the root package, but if it only adds SuperUser, it should not affect battery life).

Certain apps may drain battery. Google Calendar Provider for instance has a bug that definitely drains battery.

Edit: I updated the wiki. The key for proper battery re-calibration is pressing the reset button after deleting batterystats.bin

Another thing that may decrease battery life is Google Service Framework and Google Market. They cause wakelocks.

Disabling background sync in Settings / Accounts & Sync should help, but this will temporarely stop Market from working, so in order to use Market, you have to re-enable background sync and must not forget to disable it after you are finished with Market.
