hey guys, i'm planning to buy HTC desire. I've doubt about its battery life. My daily usage 'll be somewhat like this: Atleast 1 and a half hour music play. 2hrs browsing few photos/videos few calls lot of 'smsing'. Will the battery run out within a day if i use the phone as stated above? And 'll i be able to record HD videos with the OS update to android 2.2??
