Unable to Wipe Cache Partition on my S21 Ultra + Battery Issues

[Jhibraan]

Hello,

Recently  am experiencing issue with my battery life of my 21 Ultra.

When I bought my mobile in February, My charge was lasting around 1d 6hrs but today, 1st of May, Am getting only 15hrs of Full charge  as per the battery usage status.

Day by Day it is decreasing...
Refer to my Screenshot.

I saw a video to use the wipe cache partition to reset the battery usage status but using the Power Key + Volume Up  button simultaneously + usb cable plug in on a pc but nothing happens, my phone boot normally.

I have work profile setup on the phone, is it because of that am unable to access the Recovery mode?

Any Solutions to reset the battery usage status?

I have tried *#0228# as well but still having 15hrs of charge...

All my apps are in deep sleep as well...

Please help 😞

Try plugging it into laptop with phone still on and install drivers, once installed power off.. then volume up and power button together and hold..
