We’ve explained what happens when a phone overheats. And, we’ve linked to some useful resources to help troubleshoot specific issues. However, here are some general pointers that can help any smartphone user fix a phone that gets too hot.

Monitor Background App Usage

It is never wise to have several resource-intensive applications running in the background. Just like a computer, your smartphone can only do so much. Hence, if you’re streaming videos on YouTube, be sure that you close other applications like Facebook, Twitter, or Snapchat. Take some time to check which apps run in the background on your Android or iOS device.

App Memory Usage To Heavy For Phone

If you have a high-end smartphone like the iPhone 8 or Samsung Galaxy S8+ then this should not be an issue. However, for mid-range smartphones, listening to music, watching YouTube videos, or playing games (GBA games on iPhone or Classic Arcade Games on Android) over an extended period of time can take a toll on your phone. Hence, you may need to limit heavy streaming or gaming depending on the cell phone you own.

Bad Battery

The older the phone (i.e. how long you own it) the older the battery. And, chances are that you’ve charged your cell phone battery several times during that time. All factors that deteriorate your battery life and performance. A certain vendor (Apple) also admitted to slowing down the performance of older models of the iPhone. If your battery is defective or malfunctioning then you may get a new one under warranty. Or, you can search for a replacement on Amazon. We’ve three guides for battery replacement. For all others, be sure to go to a repair shop.

Ventilation

Do you keep your phone in your pocket for long periods of time or in a bag? What kind of case are you using? In either case, be sure that your phone gets enough ventilation when stored. Also, every now and then, take your phone out of the case. Give it a breather.

Water Damage

Do you listen to music on your cell phone while taking a shower? Do you keep your cell phone in your pocket all day? Did you drop your phone in water or spill water on your phone? Power issues and overheating are common problems that a water damaged cell phone experiences.

Any bump or knick could cause internal damage that you may not be aware of at the time.

With software, irrespective of OS updates, you may need to check for app updates to make sure that one of your apps is not outdated and causing your device to malfunction.
