Hi @Barford1011 It is actually advisable to wipe the cache partition after updates. Members should perform the following steps:
1. Turn off the device.
2. Connect To Computer or plug in USB-C Headphones , Press and hold the Volume Up key and then press and hold the Power key .
3. When the Android logo displays, release all three keys.
4. An 'Installing system update' message will show for 30 - 60 seconds before the Android system recovery menu options appear.
5. Press the Volume down key several times to highlight wipe cache partition.
6. Press Power key to select.
7. Press the Volume down key to highlight yes, them and press the Power key to select.
8. When the wipe cache partition is complete, Reboot system now is highlighted.
9. Press the Power key to restart the device.
The Repair apps option mentioned by @GoanGeek is in the same recovery Menu.

Yup went from good battery life 7-9 hours sot down to 2.5 sot with 28% left. I'm so mad
Not being rude but it has nothing to do with settings it's because of an update.
