When you watch high-definition videos or live streams, components like the screen, processor, and speakers are working continuously. Generating some heat during this process is a normal physical phenomenon. It usually does not affect the performance or safety of your phone, so please feel free to use it with confidence.
The following tips will help you control the temperature and improve your viewing experience:
I. Software & Playback Settings
1. Adjust Quality & Turn Off Effects
High definition (like 4K or Blu-ray quality) and real-time "bullet comments" (live chat overlays) significantly increase the load on the processor. We suggest adjusting the resolution to HD and turning off bullet comments. If you have enabled features like "Video Color Enhancer" or "Video Motion Enhancement," we recommend turning them off in your system settings to save power.
2. Lower Brightness & Volume
The screen and speakers are major sources of power consumption and heat. We suggest enabling Auto-Brightness or manually lowering the screen brightness. Also, lowering the speaker volume or using headphones instead can effectively reduce power usage and heat.
3. Clear Background Apps
Swipe up to open the recent tasks menu and close apps you aren't currently using. Closing background games or large file downloads is especially helpful, as it frees up system resources and reduces the burden on the processor.
II. Environment & Usage Habits
1. Avoid Watching While Charging
Charging and playing video both generate heat. Doing them together causes the temperature to rise quickly. We suggest watching videos when you are not charging, or waiting until the battery is sufficiently charged.
2. Improve Heat Dissipation
Avoid placing the phone on soft surfaces that trap heat, like blankets or sofas. If the phone feels hot, we suggest temporarily removing the protective case, or using a phone stand to keep the device elevated. This allows air to flow around it and cool it down.
3. Move to an Area with a Good Signal
Unstable signals force the phone to search for a network frequently and increase transmission power. We recommend watching videos in areas with strong Wi-Fi or mobile reception to avoid extra heat caused by poor signal quality.
If your phone still experiences severe heating (such as becoming too hot to hold, slowing down automatically, or apps crashing) after trying the methods above, please back up your important data and visit a realme Customer Service Center with your proof of purchase for a professional inspection.
