Part 1. Why Is My Phone Hot and Losing Battery?

Phone heating up and draining battery is a common problem many people experience. Typically, mobile devices overheat due to an overworked CPU, direct heat exposure, strained battery, or overuse. Also, your phone may be running on outdated software, causing performance issues. In some cases, the phone may be infected with a virus.

Below are some reasons why your phone is getting hot and your battery is draining fast:

  • Direct sunlight - If you leave your device under hot conditions for an extended period, it will begin to heat, and the internal components will get damaged.
  • Overloaded CPU - Overloading your Phone's CPU can make your phone hot and cause the battery to drain fast.
  • Faulty charger cable or battery - If your phone is too hot, you might be using a faulty charger.
  • More-than-optimal settings - If your phone heats up regularly, try to reduce the screen brightness level, choose static wallpaper, and only use your favorite widget.
  • Gaming for a long time - Like computers, playing games for lengthy periods on your phone can cause GPU and CPU to strain.
  • Streaming video on your phone - The phone getting hot and battery draining fast can be caused by streaming YouTube or Netflix videos on your phone for a long time. Anything that keeps your phone's screen lit for an extended period and uses a lot of RAM causes your device to overheat.
  • Software update - In most cases, mobile phones tend to raise temperature levels when running software updates. If a bug in your phone requires fixing during an update, there will be a temporary increase in power consumption. This can become worse if you update a rooted phone. After the update, your phone will restart and cool down.
  • Virus or Malware - Crypto-mining malware targeting cryptocurrencies such as Ethereum and Bitcoin can cause phones to heat up and drain batteries due to their resource-intensive nature.
