tigris or tristar? ( how it works ) some strange problem

6s, no water damage, all is fine but...

After every 5 minutes, when screen is off phone is going to kind of loop.

Nothing work, just hanging. Disconnecting the battery is only helps.

Questions:
 
how it work?
 
When phone works normally, power supply is implemented by PP_BAT_VCC to Tigris Chip (U2300) which is responsible for generating PP_VCC_MAIN. If the Lightning port is connected, (then Q2300 is "opens") and PP5V0_USB is used to generate PP_VCC_MAIN.
 
In my case, it looks like Tigris is not working properly. But when "hanging" PP_VCC_MAIN is ok (approx.V=4,2). This leads me to suppose that the circuit PP_BAT_VCC is damaged (somewhere).
 
Can anyone explain how the PP_BAT circiut works? (in logic)
 
- thanks
