Do you actualy get 7 days of standby time? My t68i says it'll get 7 days when you unplug the charger, but i don't think it has ever broken 4.

I never go that long without charging it to be honest. I know it says that but it would be interesting to find out. I might have to test that.

What is odd is that turning on bluetooth lowers the time estimates dramatically but the actual standby time.

When I toggle my bluetooth on and off, it does lower and raise both standby and talk times. I usually keep the bluetooth on, though, because with 7+ hrs of talk time and 7 days of standby, who needs to worry about running out of battery? I have a charger at home, work, and a friend's house where I stay quite often. Battery life isn't an issue for me.
