I think I found out why my batter suddenly dropped to 2-3 hours each charge. I opened the battery and cleaned the battery terminal on both the battery and the phone with a pencil's eraser. I'm still using my 10 months old battery and the life of it is even better than when it's brand new. Before on a regular day, I can go about 14 hours of light use before I need to charge it. For the past 4 days, I get about 35 hours before it beeps low battery. I hope this info can help someone out.
