Anybody else have one of these? Just wondering what your battery life has been like. I got a defective battery with mine so I threw in a battery from my mx5000, while I wait for the replacement - model number is the exact same. Battery life seems horrendous. I mean I can't come home at 6 and casually browse TV until 10... and I mean really casually. I've set WiFi to timeout after 10 minutes, turned brightness way down and set haptic feedback to the lowest setting. Anybody else having this issue? Have any tips?
