Help Extended Battery drains 75% in 5 hours?

[Kmw63]

I took the phone off the charger at 3pm. Almost immediately it drops to 92%. Over the next 5 hours I had two calls totaling about 15 minutes and listened to some music using MixZing for about 2 hours. At 8pm the battery was at 25%. WiFi, Gps, Bluetooth etc all off. This is a Sprint 2600mAh battery I've had about 3 months. Previously I was getting 20-24 hours with heavier usage. Any ideas? Phone is not rooted.

Do you have the app spare parts. You can narrow down the battery usage with that app
