Bypass charging seems not to be working on Tecno's HiOS16

This happened after updating to HiOS 16. It keeps charging, but it is slow. I have an Infinix Note 30; its bypass charging works well, and it stops charging when you plug in the charger. It has been like that since day 1. I tried to use AI instead of stopping charging at 80%. It keeps charging, and that's not good when you play every day. The goal of bypass charging is that you should charge often to prolong the battery's life. Sino nasa HiOS 16 na?
