Seems fairly normal. These things fluctuate so they won't always be the same and won't always be at the peak right away either. Keep in mind that an iOS app like Battery Life gives just an estimate and only rounded to the closest hundred basically.Four days of use, and again:
Battery Life app:
4% wear level
Capacity: 1500/1560 mah (96%)
Ibackupbot:
CycleCount: 3
DesignCapacity: 1510
FullChargeCapacity: 1500
Battery is degrading very fast according to this.
