Hi, I bought an LG Optimus Black P970 about a month ago. And in the past couple of days it started draining the battery really bad. It was pretty much full charged when I went to sleep, woke up in the morning and it was at 30%. Couple of texts take about 20% every time. The battery use shows 50% - Mobile Standby, 49% - Phone idle, 2% - Diplay. I've also checked time without signal - 0%, so it can't be it. I don't have a data plan, so don't use 3G. I tried turning off Wi-fi and background data - didn't help. Any ideas? It drived me crazy - what is using up the battery overnight?? I don't really have any apps on it either. Please help! PS It's not rooted.
