alright so for the past three night i have had my new 3g iPhone i have been doing a test. when i get the 20% warning i turn off wifi and just have 3g. i go to safari and surf until i get the 10% warning. Saurday night i got 20 Min. Sunday i got 24 Min. monday(last night) i got 25 min. so for anyone that wanted to know about how long surf time you get in this time frame(i know i did ) you should be able to get alteast 20 minutes in that time. i thought it would be like getting like 10, maybe 15, so im very hapy. also i was at my home so i mean i only get 2-3 bars and sometimes 1 bar of 3g, so keep that in mind. if i had full bars i think i would of gotten better battery times. also the battery is betting better with the charges because im increasing time.
