========================================
My phone is discharging at the normal rate, but charging is taking countless hours. If I am using the phone while it is plugged in it loses power even. Turning the phone off and leaving it to charge doesn't fix it as it continues to charge very slowly.
I am using the same charger I have been using since I had the phone a year ago. The charger is fast charging other phones. I have also test with other chargers I have around the house but it didn't fix it.
It is important to note the problem isn't that there is no fast charging, the problem is it is barely slow charging. I went to sleep yesterday at 52% battery and woke up 7 hours later it has only charged to 93%.
If I turn battery care on and set the time I want it to charge it will say fast charging on the lock screen, but it still charges at the same slow rate. If I disable battery care it doesn't say fast charging and is maybe a bit slower not sure.
When I plug it into the charger the battery has the lightning bol symbol and two + signs.
I've had this phone for a while now and it had been outstanding, the battery life is spectacular, and it still is. When I woke up this morning at 93% I used the phone all day and I'm now at 35% after heavy usage. But charging is taking forever.
It seems to me that with the latest update something happened with the software that locked the charging rate to very low? Please let me know if there is any fix! I also tried enrolling my phone now in the beta program to hopefully download the android 11 update to see if that would fix it, but it seems I'm too late.
Thank you!

Just a quick update, I made a phone call and used the phone a bit and it has dropped back to 42%, it is basically BARELY accepting a charge.
I am now charging over night as much as I can and then slowing down discharge during the day by keeping it plugged in so I can charge higher during the night the next night. The battery is not discharging quickly while mobile, it is performing perfect as always, the problem is literally in charging it up, all I can tell is some hickup happened during the update and it has to be a bug because it was literally one way before the update and immediately a problem after the update

Speed of charging showed no difference between fast charger and normal charger, both equally slow

Also finally I am using a battery pack to charge the phone and it indicates how much of it has been used and it barely lost any power overnight which means the phone is barely drawing any power to charge
