sw6208 power bank

The board in question has been revised to three versions, and I have looked through the schematic diagram many times and it seems to be fine. I wonder if the manufacturer has drawn the schematic diagram wrongly. Can anyone give me some advice?
First picture.
This is the version that completes all functions. I have been thinking about it for a long time, but the test also found a little flaw. The chip will get hot under fast charging and will automatically protect itself after a period of time.
The temperature is still not well controlled here.
The protection board IC can be DW01 (direct replacement). The protection chip I chose protects the battery to the maximum extent without severely squeezing the battery performance.
The shell model will have to wait a while.
The sw6208 is really difficult to make. There are many things to pay attention to, and the official schematic is not marked on it. Newbies who want to make their own power bank board are recommended to change the chip.
