Yes, many users have reported experiencing similar problems. This can be due to the phone re-optimizing itself after the update or apps needing to be optimized for the new firmware.
Add apps to the "deep sleep" list to prevent them from running in the background and draining battery.

Clear app cache to remove temporary data that can impact performance and battery usage.
Resetting battery statistics can sometimes help.

Adjust background usage limits in Settings > Battery and device care > Battery > Background usage limits.

Choose options like "Put unused apps to sleep" or "Sleeping apps" to restrict background activity.
