As the T3 is usinguses a 400MHz processor, using the same 900mAH battery from the T1 and T2 just doesn't cut it. The best way to extend the battery life of a T3 easily, is to use underclocking software like PXA clocker, Lightspeed or Warpspeed. This can give about 5-6 hours of runtime. However users who uses [[Bluetooth]] and [[Wi-Fi]] extensively will find that even with underclocking, the battery life is still rather short as wireless usage tends to use up more power.
