A few months ago, we compared two 4-inch dual sim Android phones, the HTC Desire V and the Lenovo P700. The Lenovo was 33% or so cheaper and came with a larger 2500 mAh battery. While this is subjective, the HTC phone has a classier chassis, a more polished Sense user interface and comes with a decent sized 1500 mAh battery.
Battery life is one key deciding factor in smartphone selection. So how well does the HTC Desire V do. Not bad actually, based on GSMArena's battery life tests. The HTC Desire V gives you over 8 hours of talk time, over 6 hours or video playback and just under 6 hours of web browsing time. Good enough!
