sounds like a possible u2 power ic that needs to be replaced.

Try below methods:
1. Check if the connection between the USB port and the charger is loose.
2. Check if your charger is in good shape and always use original charger.
3. Double check the USB charger port on your device.
4. Check the battery to see if it’s aging or bulging.
5. Check if the battery contacts are in good condition.
6. Check the resistance with a multimeter to confirm everything is working normally.
7. Check if the U2 IC chip is inveraciously soldered or damaged.

Often times battery draining problem means U2 IC chip is failed to work properly.
You may want to use thermal camera or freezer to test it. Go ahead and spray freezer, let it cool down and connect AC voltage 4.2V on and you will see U2 highlights itself. And AC meter show about 0.22W. Also, while testing with camera U2 gets warmer and it highlights itself as it turns red in camera display. I hope it will help!
