I updated to the leaked version of 10.2.1 on Sunday. Monday and today I have noticed that the battery life is HORRIBLE now. Has anyone else noticed this change? I was running a pretty old OS version before hand. The device monitor says the system was using 46% of the battery today. I took it off the charger at about 5am today and I was down to 20%! around 2pm. I never had the battery drop to below 30% until like 9-10pm if I was using it heavily.
Only changes... added another e-mail account and upgraded to 10.2.1.
