No worries! If your Samsung A52 5G has battery drain issues after an update, try clearing the cache partition. Turn off your device, then hold Volume Up + Power buttons until you feel a buzz. Release the buttons, select "Wipe cache partition," confirm with Power, and choose "Reboot system now." That should help!
Wiping the cache partition will not delete any data, but if you accidentally select "wipe data," it will delete everything. Therefore, please ensure that you choose "wipe cache partition" before proceeding.
