About a month and a half ago, my year-old 8220 started burning battery at a high rate. Where it used to last 5-6 days on one charge, it went only 2. It even lost 10-15% of charge when powered off overnight! I know it wasn't the batteries because I have 3 I swap out and charge externally. They all held their charge when out of the phone. I made sure wifi and bluetooth were off and I don't use any apps other than call, SMS, calendar, and rarely playing a track or 2 off the SD card.
I successfully upgraded to the latest firmware and it still had the problem. Went through a Master Reset with tech support and it still burned battery.
After all that, tech support agreed to send me a replacement and it works perfectly. I have been running on one charge all week.
The moral of the story....sometimes it is hardware.
