Addressing Sudden Overheating and Rapid Battery Drain on Your iPhone 16 Pro Max

Experiencing unexpected device issues can be frustrating, especially when your iPhone 16 Pro Max suddenly overheats and drains its battery quickly without warning. If you’ve encountered a situation where your phone’s battery is depleting rapidly and the device is overheating, here are some causes and actionable steps you can take to troubleshoot and resolve the problem.
