Compared to classical mobiles, most smartphones already look a bit fat, not mentioning the case if instead of the original battery one chooses a different with a higher capacity. The Seidio Innocell 2,600 mAh battery (pictured below) for T-Mobile G1 offers about double the operating time that has been provided by the original 1,150 mAh model, but the increased capacity comes with a battery that is about twice as thick, so it can only be used together with the back cover included in the $55 dollar package. According to Engadget, Apple iPhone has triple the uptime than T-Mobile G1 with the default battery so there is quite a lot of room for improvement in power management for HTC's phone.
