What you are pointing at is L9, An inductor for LED flashlight. U17, which is right next to L9 under the shield, is somehow shorted, which causes L9 to constantly run on full power.

I removed the L9 and now is not overheating anymore nor the battery is draining.

The only drawback is the Flash is not working
