One of the major causes of overheating in the Samsung Galaxy Z Flip 4 is the apps running in the background. Some apps, especially those that require a constant internet connection, cause the device to heat up significantly. Identifying these apps is the first step in resolving the overheating issue.
You can do this by going to:
- Settings > Device Care > Battery. Here, you will see a list of apps and their power consumption.
- Once you’ve identified the apps, you have two options. If the app is not essential, consider uninstalling it. To uninstall an app, simply go to Settings > Apps > [App Name] > Uninstall.
- If you still need the app but don’t use it frequently, you can put it to sleep. To put an app to sleep, go to Settings > Device Care > Battery > Battery usage > Sleeping Apps > Add. Then select the app you want to put to sleep.
By uninstalling or putting unused apps to sleep, you can significantly reduce the heat generated by your Samsung Galaxy Z Flip 4. This not only helps in cooling down your device but also improves its overall performance and battery life.
Fix 02 – Avoid Using The Device While Charging
Fast charging is a feature that many modern smartphones, including the Samsung Galaxy Z Flip 4, possess. It’s designed to get your device back to full battery in the shortest amount of time possible.
However, this rapid influx of power causes your device to heat up. This is because the process of charging itself generates heat, and when combined with the heat generated by usage, it leads to overheating.
For this reason, it’s advisable to avoid using your Galaxy Z Flip 4 while it’s charging. This doesn’t mean you can’t use your phone at all during this time, but try to avoid intensive activities such as gaming, streaming videos, or using GPS, as they can strain the processor and battery, leading to increased heat production.
Another important aspect to consider is the type of charger and cable you’re using. Not all chargers and cables are created equal. Some may not be up to the standard required for your device, leading to inefficient charging and excessive heat.
It’s always recommended to use the original charger and cable that came with your device, or at least ensure that any replacements are of a similar quality and specification. This maintains the optimal charging speed and prevents any unnecessary heating issues.
Fix 03 – Reduce the Brightness
High brightness levels require more power, which in turn generates more heat within the device.
The device’s AMOLED screen, while providing vibrant colors and deep blacks, generates a significant amount of heat when brightness levels are set high. This is because each pixel on an AMOLED screen is individually lit, and the brighter the pixel, the more power it consumes.
To reduce the heat generated by your device, lower the brightness level. To do this by going to
- Settings > Display > Brightness level and adjusting the slider to a comfortable level that is not too high.
- Alternatively, you can enable the Adaptive brightness feature, which automatically adjusts the brightness level based on the lighting conditions in your environment. To enable it go to Settings > Display > Adaptive brightness and toggling the switch to the ON position.
- Avoid exposing your device to direct sunlight for prolonged periods. The sun’s rays can cause your device to heat up quickly.
Fix 04 – Turn Off Unused Features
Another reason your Samsung Galaxy Z Flip 4 might be overheating is due to the overuse of certain features that demand a lot of power from your device. Features such as Bluetooth, GPS, Wi-Fi, and Mobile Data are high power-consuming features that cause your device to heat up if they are left running in the background for extended periods.
Here’s what you can do to reduce the heat generated by your device:
- Turn off Bluetooth: it is best to turn this feature off if not in use. To do this go to Settings > Connections > Bluetooth and toggle the switch off.
- Disable GPS: If you are not using any apps that require your location, turn it off by going to Settings > Connections > Location and toggling the switch off.
- Switch off Wi-Fi: If you are not using Wi-Fi, turn it off. To do this go to Settings > Connections > Wi-Fi and toggle the switch off.
- Disable Mobile Data: Turn off Mobile Data when not in use. To do this go to Settings > Connections > Data usage and toggle the switch off.
Please note that the idea here is to turn off any unused features to reduce the amount of heat the device generates. This doesn’t mean you shouldn’t use these features.
