Battery drain with AP heat.

This phone has a power problem. I recently replaced the battery and it has a life expectancy of 100 percent.

However, if you leave the screen on without doing anything, the battery will be used 5 percent per minute. This is accompanied by heat generation in the AP region covered by the metal plate on the motherboard. Sometimes, when no heat is generated, the battery consumes relatively slowly, but still consumes quickly.

I tried factory reset and boot with the display and home button module removed, but the problem was not solved. This does not appear to be a short circuit by the display and the home button module. I couldn't test the battery because I didn't have an extra battery.

I don't know if it's because of the bad battery, or if it's heat and battery consumption due to a short circuit in the chip.
