What's your overall battery life? Over what span of time is it using 96% of your total battery usage? If you only checked after about 5 minutes, that wouldn't necessarily mean a whole lot. If it was over 4 hours of use, with the battery dropping steeply, that's clearly a problem.
Charge up to 100%, then let it drain to 20-30% with normal usage, without charging in between. Then show us:
1. The main Settings>Battery screen.
2. The fullscreen battery graph screen (which shows Awake time and Cell Signal Strength).
3. The Screen category (to see total Screen On time).
4. The Cell Standby category, if present (to see Time Without Signal).
