well it is found that using 4G is a super battery sucker especially since the TB has a substandard 1400mah battery (evo,arrive and tp2 have 1500mah battery) u would probably get 2 hours of consistent use at the most but with it in just 3G mode u can get up to 4 hours of consistent use provided that u have a good signal. so hope that helps.
