Hi, I am now 2 days using FW 3.1, and feeling that it has better battery life?! synched today some new games via USB (USB charging is imho LESS efficient then power plug) and charging it a bit then, after disconnect battery 92 % After Using 1 Hr., 14 Min. Standby 3 Hr., 4 Min. (both times counted after disconnecting from usb) I had 81 %! At that using I had W-Lan enabled all time , 12 min. Internet, 20 min. IRC, a 4 Min. call, rest gaming, including 20 min. Adrenaline Golf Online over WiFi Multiplayer. That Golf Game present 3D effects only for 3G S, looks like high GPU/CPU use. Video http://forums.toucharcade.com/showthread...adid=24919 At 3.0 or 3.0.1 I wouldn't have 81 %, I would have about 66-69 . So my feeling right now is a better battery life under 3.1, a lot of people in other forums had problems with the battery under 3G, especially 3G S because it was advertised with "better battery" So can anybody confirm better batter life on 3G S with 3.1?? Thanks defaude
