Improving Smartphone Overheating for Better Streaming

Android, iOS

As the weather gets hotter, the temperature of the smartphone performing live streaming also rises.

And when the temperature of the phone rises like this, the performance of each module in the device, such as the CPU, GPU, and network module, decreases overall, which lowers the quality of your live streaming.

That’s why we’ll guide you through 9 ways to reduce the heat of live streaming, which especially requires the full power of your smartphone, to make your live streaming more stable.

Removal of the battery charger

Charging the battery is one of the factors that increase the heat of the phone the most, so please fully charge the battery in advance and start live streaming with the charger disconnected.

If you need to live streaming for a long time, starting it with the charger disconnected and then reconnecting the charger when the battery is exhausted is a way to minimize the heat generated by the charger.

Removal of the smartphone case

The smartphone cools itself by dissipating heat through its body, so the phone case blocks the heat dissipation, which eventually increases the heat of the phone.

That’s why we recommend that you take off your phone’s case for +a while during live streaming.

Adjusting the screen brightness

The display of a smartphone is one of the elements that generates significant heat. Adjusting the screen brightness to a slightly lower level during live streaming can effectively reduce the heat generated by the phone. This adjustment can also help slow down battery drainage.

However, if you adjust the brightness of the screen too dark, it may be difficult to observe the live streaming screen, so please check the appropriate level through tests in advance.

Use of cool patches and cool packs

Cool patches and cool packs, which are easily available in the market, can also help lower the heat of your phone.

If you attach it to the back of the phone in an appropriate size, it will help to lower the heat. However, do not forget that it should be removed in a timely manner as it may block the heat dissipation when effectiveness is exhausted.

​Of course, fan-generated wind can also help reduce heat, but it's important to note that the noise from the fan might be picked up during your live stream.

Sufficient smartphone cooling

There are cases in which live streaming is started while the phone is already overheating due to prolonged test streaming. In this situation, as soon as you start streaming live, you may experience degradation of its quality due to heat.

So, if the phone is overheating due to test streaming, please allow the device to cool sufficiently to the normal temperature level before starting your new live streaming.

Reboot your device

​Please reboot your smartphone right before live streaming. It can close the apps running in the background of the device at once, which can help reduce heat and improve the condition of the phone.

This is one of the most recommended methods, and if you’ve ever had issues with live streaming, remember to reboot your device.

Reduce the use of media overlays

Media overlay that shows images, videos, and webpages together on live streaming video has the effect of enriching live streaming. However, since this requires additional computation to the device, it may generate additional heat.

So, if your phone gets very hot during live streaming, please note that reducing the use of media overlays can help ensure stable quality.

Reduce the use of effects

The PRISM mobile app provides various types of effects. There are effects that can be done without the device’s calculations, and there are effects that require additional calculations from the device, such as an effect that recognizes a streamer’s face. The latter effects require continuous computation of the device because the user’s face needs to be recognized in real time, which may cause heat.

So, if your phone gets hot during live streaming, reducing the effects you are using one by one will help to lower the heat.

Use of high-performance smartphones

Live streaming is a very heavy task for a smartphone. This is because it requires three processes to run simultaneously: capturing video from the camera, applying various effects, and streaming the video to the live platform's server. So it requires a lot of computation of the device, which can cause the device to overheat.

In general, it is advantageous to use a high-performance smartphone for heat issues. However, even if it is a high-performance device, there are devices that are sensitive to heat, so it is recommended that you check carefully and prepare the device.
