How to fix an Overheating Android

Apart from the regular wear and tear which accompanies charging-discharging a battery, overheating is another reason why a battery could stop lasting as long as it used to, swell up or stop retaining charge entirely. In this brief guide, we’ll be looking at the common causes of an overheating Android phone and what to do when you are experiencing such on your device.

What could cause an Android phone to overheat?

Common causes of an overheating Android phone are:

  • Incompatible charger: The charger might be too powerful or not powerful enough for the phone
  • 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 screen savers , high screen brightness, 3G, Wi-Fi, Bluetooth etc could result in overheating
  • Over-clocking: Overclocking is like setting the device to work in turbo mode by default, definitely a recipe for overheating
  • Heavy usage while charging: Using CPU intensive processes / heavy gaming while charging is another possible cause of overheating
  • ROM bug: Some ROMs (stock and custom) have power related bugs
  • Buggy / Rogue application(s): A rogue application could be consuming system resources selfishly
  • Hardware bug: Some Android phone models are notorious for overheating
  • Poor network coverage: If in an area with poor network coverage, the radio will keep searching for signal and this tells on the battery
  • Insufficient ventilation: Stuffing the phone in your tight pocket, handbag or case could cause it to warm up mildly

When faced with an overheating Android, consider the following fixes:

  • Try a different charger: Avoid charging the phone using a PC, consider using a wall charger specific for the phone
  • Battery Replacement: Consider replacing the battery if it gets full or goes flat too quickly
  • Exit unused apps: Ensure to close (not minimize) apps not in use for an extended period
  • Save power: Ensure to limit the use of screen savers. Also, avoid setting the screen brightness too high; automatic Brightness should be just fine  (see https://journal.hovatek.com/how-to-make-an-android-phones-battery-last-longer/ )
  • Disable unused radio: Enable 3G, Wi-Fi and Bluetooth only when needed
  • Avoid heavy usage while charging: Avoid running CPU / battery intensive processes while charging
  • Revert to stock ROM: If this issue began shortly after flashing a new ROM then consider reverting to the previous one
  • Remove rogue apps: Closely monitor which applications cause the phone to lag / heat up and uninstall / replace them
  • Switch to Airplane mode: If in an area with poor / no reception, switch to airplane mode when signal isn’t needed
  • Allow for proper ventilation: Avoid placing the phone in ill ventilated areas or beside hot objects
  • Device replacement: The overheating might be due to a hardware bug / defect. Consider a replacement if the device is still under warranty
