I got the Android 2.2 update a few weeks ago and have noticed my phone get steadily slower after that. With my usage pattern I would recharge my phone once in about 2 days, but now it needs daily charging. Interestingly, the highest usage is now reported as Voice calls (used to be 'Display' earlier), but my voice usage patterns are unchanged. Also I do see Google.Services.Framework consume higher memory than before.
Anyone else noticed the slowness, battery usage issues? At times, the phone just freezes when an there is an incoming call when I am on the phone.
