I just moved from an iPod touch 2G to an iPhone 3Gs. As far as I like my phone, I have a little concern with the battery. So far I have charged the phone 2-3 times and everytime, I get the same result and Id like to know if its normal. 1) The phone will almost go from 100% to 85% charged in a matter of minutes. Than after, it will go down from 85% much slower. 2) Compared to my Ipod touch witch lasted 3-4 days (emails, and about 1/2 browsing), the iPhone will last about 36 hours (id say 2 1/2 hours of use, the rest standby. I find it a bit short since at that rate it need to be almost charged everyday... 3) The first day I got it, I played with it abit and when I put it in the table before watching a movie, it was at 70%. Then, a hours and half later....9% !! It did not re-happened yet but what could have caused such a drain ?? 4) What would you recommend. To only charge it when its dying or to leave it plugged in all day when im at work ? Will letting an iPhone plugged all day improve the battery life of decrease it?
