[Profy_X]

Hello!I have a problem with my elf the battery is dead it stays charged only 1 day but is a non OEM battery (TVM 1100mAh) the question is what should I buy a OEM battery 1100 mAh or a non OEM 2500 mah wich one stays charged longer?

Whether its a genuine HTC battery or not, it shouldn't play too much into it. Definitely the 2500 mAh will give you more than twice the regular battery life.
