I recently updated my phone to CPH2173_11_C.48 (April 2022 Security).

When the phone is on the fast charging shows but the battery % does not increase, in fact the battery drains when used.

The only way I can get it to charge is by first connecting the charger and then turning off the phone. After it starts charging (and the charging % increases), I can then turn the phone on and it charges properly even whilst using the phone to watch videos.

The only thing I have done recently is to update to the latest firmware.

Any ideas what the issue may be?

Noticed something a bit weird, I connected the phone to my PC and it is charging slowly (normal charge, not fast charge). When plugged into an outlet, it shows fast charging but the % does not go up (unless the phone is off).

Could this be a software issue with fast charging? Any way to fix other than to try factory reset?

If you do the above process then unplug and plug straight back in, does the problem replicate?

Does it only happen below or above a certain battery%?
The culprit looks to be fast charge at lower battery %. I can slow charge at lower battery with the phone on and fast charge at higher % ( around70% +). Whilst off, fast charge works at any % battery.

Could this be software or hardware issue. Problem persists even after factory reset.
