Basically I have got my Samsung Galaxy S21 FE a year ago on June 2022. It wa great, the phone was amazing until recently when it automatically updated by itself even though I didnt want it too but its okay I turned of Auto Update but now my battery is draining so much. It has went from Android 12 to Android 13 but the battery decrease is insane. I am wondering if anyone is having the same problem with their S series.

It's probably worth wiping the Partition Cache

Wiping the Partition Cashe clears out a lot of old or corrupted information that can cause issues

Follow the steps below. You must follow every step and you should be done in about a minute

Turn off your phone.

Connect your phone with a USB cable
to PC or another Samsung mobile

You will see the charging icon on your screen.
Wait till it shows charging with battery percentage.

Next, press and hold the Volume up and Side key simultaneously.
You can press the volume up button just before the Side key.
The Samsung Logo followed by
Samsung Galaxy appears on the
screen.

At this point, release the keys
Phone will boot into Android Recovery mode

In Android recovery mode, using Volume keys, choose "Wipe Cache
Partition" .
Use the power button to accept that.
You will then see its cleared.

Then the top option, reboot phone.
Press the power button to reboot the phone and then sign in normally

No it won't affect what you have installed.
All it does is clear out things like old cookies, Old temporary files etc Just Cashe Data that can build up over time
The data and information on your phone won't be affected

I normally do this after any large software updates

Well I did the partition cache, my storage has lost almost 1GB but my battery draining got kinda worse. My phone ended up updating by itself to Android 13 3 dayd back anf from there it is not doing good. Maybe I should do another software update (September 2023) Will that improve anything because I feel like it kay destory battery more ngl.
