In the past week or so, I've noticed my battery life drastically decrease. I could easily go a day and a half with moderate use (some web surfing, all my apps and widgets going, etc.). Last week, my battery was gone one day in about 7.5 hours. I thought it was from installing Screebl Lite. I disabled Screebl, same problem. So I uninstalled Screebl, same problem. I have Spare Parts installed, but it's not the most intuitive thing in the world. I try looking at the battery usage stats, but it says "Android System" is the biggest battery user. And I don't know what is good, what is bad, what is normal. Any help is appreciated. Example: Today, I had my phone at 100% charge. Took it off the charger around 10 AM. Around 11:00, I paired up the new Bluetooth headset I got for Christmas. I made a call. Listened to a couple of songs. Watched a couple of minutes of video. I browsed the Market for a few, disabled bluetooth and went about my day. By about 6:00, I was at 5%.
