Hello Guys. I installed the 1.6 but I notice a battery life is less than the GalaxHero! Example: Finish charge yesterday at 20, switched into standby until 00:30, put on the Airplane mode until 7:30.....charge battery to 91% Until now, almost always on standby, 3 minutes of calls, 5 minutes of WiFi connection....Battery 60%! I think it wear the charge very quickly ... What do you think? I also noticed a bug on connecting / disconnecting the cable from the PC, if I check "Notify SD Card" or if I not check it the phone rings, too!
