BGR on the Thunderbolt's poor battery performance
What makes matters worse is the fact that 4G can’t be switched on and off by the user. There is no widget to disable LTE and there’s not even a menu setting you can check on and off to enable or disable 4G. While there is a method floating around to do this by entering into the phone’s field test mode, this doesn’t even come close to cutting it. While enthusiasts might be comfortable with a “hack” like this, the average consumer will never even know the option exists.
I would go even further: It’s asking a lot of the average consumer to have to actively manage yet another antenna just to save battery life. Make it work, or don’t ship it. 4.5 hours is not acceptable.
