So after a full charge and almost completely dead here are my stats. Would you guys say they look bad, or are pretty fair?
Usage: 7 Hours, 20 minutes (lots of Wifi web browsing)
Standby: 21 Hours, 33 minutes
Call time: 1 Hour, 2 Minutes
Push ON for 2 email accounts
Wifi ON
3G OFF
Notifications OFF
Location OFF
. . . So, that being said, today I used the phone heavily, lots of web surfing via both wifi and 3G, lots of speedtest tests on 3g, which must be tough on the battery, about 30 min 3G calls, some email and sending large pics, but, no ipod, and I hit the 50% mark at exactly 3.5 hours of pretty hard usage. It'll be interesting to see how accurate the battery indicator is, and if that number doubles or not, I did run it to zero last night, then fully charged, so it should be accurate.
Whenever I used my 3Gs this hard, with no ipod, I was lucky to get 5 hours, so, it seems I'm getting 2 hours or so more use from the 4. Not bad. . .
Lots of these folks have over inflated numbers because stuff like Ipod usage etc counts.
With very heavy usage you should be able to do 6 - 7 hours using lots of wifi. Maybe with just 3g Data you are looking at 5 hour range.
These folks who are doing 10-11 hours keep in mind lots of IPOD usage. Even Slacker Radio does not use that much battery. I can do 6-7 hours using heavy ISTOCKMANAGER on WIfi which is a stock streamer that is constantly updating.
