If your smartphone is getting hot while using certain sophisticated apps, this can be completely normal. The computing power of the device is required and the electricity consumed is also noticeable as heat. Even when charging the cell phone, both the transformer and your device itself can heat up slightly – no need to worry. If your smartphone gets really hot, however, something is wrong.
What helps if the smartphone gets hot?
Try a different charging cable
If your smartphone only gets hot when you are charging it, the problem may be with the charging cable. Either the cable itself is damaged or the transformer is no longer OK. You should also make sure that the transformer has the correct amperage and power. Some transformers deliver more electricity than the cell phone actually needs. When this is the case, the additional electricity is converted into heat. It is best to always use the original hardware of your smartphone. If in doubt, buy a new charging cable from the manufacturer. In this way you can ensure that the transformer and cell phone are really compatible.
Close apps regularly
If you do not close your apps after using them, they will still be active in the background and drain the battery. This is why you should actually close an app after using it. You can find out how this works in the operating instructions for your smartphone. Regularly emptying the cache can also help:
- Clear your Android device’s cache
- Clear iPhone cache
Find responsible apps
Active apps may be causing your smartphone to warm. Some apps are poorly programmed or require a hardware capacity that your smartphone cannot or only with great effort. You should always check whether your mobile phone has enough memory for the apps you are using. If you suspect that an app is consuming a lot of power, you can try uninstalling it. If your cell phone does not warm up, or only barely warms up, you have found the culprit. Read here how to control and empty the RAM on Android.
Compatibility problems of apps and operating system, as well as errors in the respective software can also cause the cell phone to increase in temperature. You should therefore regularly carry out all updates offered for your operating system, i.e. mostly Android or iOS. You should also keep your installed apps up to date. As a rule, your mobile phone will automatically suggest possible updates.
Switch off the WLAN connection
As soon as your smartphone is physically removed from a known WLAN, it tries to reconnect again and again. It will continue to do so until it has found a known or new network. The constant search for a connection strains the battery and can ultimately lead to the cell phone heating up. You should therefore switch off the WLAN connection when your smartphone gets hot and you do not need the Internet at the moment.
In order not to unnecessarily burden the battery of your smartphone, you should avoid completely discharging it. Most devices give you a warning when the battery level is 15%, then you should plug it into a power source.
Avoid warm places
You should be careful where you put your smartphone. The warm window sill directly above the heater in winter or the dashboard in the car in summer are places that can permanently damage your device.
Contact repair service
If none of these tips really helped you, then it’s time to get your smartphone repaired. The battery may be defective and practically overheat by itself. This can also be dangerous in the long run because the heat could cause the battery to expand or even explode. It is always better to be safe than sorry here. If your smartphone is getting hot and is still within the warranty period, the manufacturer’s own repair service is even free in most cases.
