Welcome to Android Central! More battery stats would be helpful as well. 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).
Also, something I always do after a major update is uninstall and then reinstall heavy apps, especially third party launchers. Don't ask me how but it works.
