Hello,

With any new version of iOS there are always maintenance and re-indexing tasks to be performed. It should settle down in a few days. These are the standard steps for short battery life:

1) Have you tried a restart?  If not, do it now.

2) Go to Settings > Battery > BATTERY USAGE BY APP to see the apps that are consuming your battery.

3) Check “Battery Health” in the link: 

iPhone Battery and Performance

Good luck.
