  • Damaged battery: A damaged battery will not charge / discharge efficiently, resulting in overheating
  • Running too many heavy apps at a time: Running too many apps or too many processor intensive ones at a time will increase the CPU load, causing the device to heat up
  • Battery intensive processes: Battery intensive processes like high screen brightness, 3G, Wi-Fi, Bluetooth etc could result in overheating
  • Heavy usage while charging: Using CPU intensive processes / heavy gaming while charging is another possible cause of overheating
  • Buggy / Rogue application(s): A rogue application could be consuming system resources selfishly

  • Poor network coverage: If in an area with poor network coverage, the radio will keep searching for signal and this tells on the battery
