I just bought an HTC EVO V 4G from virgin mobile and have realized that the battery life is terrible. Just going on facebook for 5-10 minutes using wifi drains the battery about 10% or so (not to mention what taking a picture with 3D on does to it). I have auto-sync turned off and don't use 4G or 3G at all right now. I have it rooted and S-off and have tried a few different ROMs that claim to greatly improve battery life, all to no avail. The only things I can think of to do next is to buy an extended battery (which I don't even know if its worth the price with this phone) or buy a whole new phone. I have always used moto droid phones whose batteries last 2 days for me, so I am new to issues involving batteries. Please help!!
