[ASMR] Modding iPhone 15 Pro Max Cooling System, Nearly Botched It!

This second-hand iPhone 15 Pro Max from our follower suffered from severe overheating after A period of time of use, with 85% battery health after 458 cycles. We upgraded its cooling system and replaced the battery. We applied nano carbon copper foil on the motherboard and display, filled gaps with thermal gel, and used a custom pure copper baffle with Laird thermal pad. We also installed a 4780mAh SeFu high-capacity cell with original zero-cycle flex cable, 0.2g lighter than stock. Battery health returns to 100% with greatly improved heat dissipation and reduced thermal throttling.
