Droid X2 user here. (& Very much the noob). I'm going under the assumption that I probably just need a new battery (had it for a good 2 years now) But it seems to drain pretty quickly & when I charge when the power is off, it seems to jump percentages Very fast. Like, it'll go from being 30% to around 80% & I *know* it's not really that high. So- new battery or a different fix?
