I've had my D3 for about 3 weeks now, and for the first 2.5, I could go all day on my battery and still have a lot left at the end of the day (50-70% remaining, usually). Suddenly, a few days ago, my battery died at around 1pm, and the phone shut off. The next day it drained almost as fast. I've noticed the phone being a bit warm in my pocket, and the battery is losing about 10% per hour, just idling in my pocket for most of that time. I've checked the battery stats, and there's no runaway processes. As most have noticed, the vast majority of usage is by 'cell standby' and 'phone idle.' I'm not in a low signal area, and I haven't changed my location or phone habits from the first few weeks I had the phone. I thought maybe my batterystats were just getting skewed by me charging the phone every night, but for 3 days in a row now I've had to let it drain fully, then recharge, so that should help correct for that, yeah? Any ideas on why I have the sudden change in battery life??
