After I received the OTA to 2.1 I have noticed more lag when scrolling between home screens, using 2D games is painful with the framerate reduction, and many items that are running in the background without me ever starting them. I also cannot seem to keep them closed either. I can also say that I am getting worse battery life now than I was with 2.0.1. I was wondering what would actually happen if I rebooted into Recovery Mode and did a Factory Reset with Data Wipe. Would this possibly help with the update causing these problems that were not there before? Thanks for any help with this.
