How to prevent overheating when distributing Wi-Fi

Redmi 9 equipped with a processor MediaTek Helio G80, which is prone to heating up under prolonged load. If the temperature exceeds 45°C, the system starts throttling (artificial performance degradation), which results in a drop in internet speed. Here's how to avoid it:

• 🧊 Use cooling:
  • Remove the case (especially the silicone one - it retains heat).
  • Place your phone on a metal or ceramic surface (it conducts heat better than plastic).
  • In case of critical heating, use an external cooler (for example, USB fan for laptops).
  • ⚡ Limit background processes:
    1. Close all applications except those necessary (especially games and social networks).
    2. Turn off automatic app updates in Google Play.
    3. Activate Battery saving mode (but not Super savings - it limits the internet speed).
• 📶 Reduce the load on your modem:
  • Limit the number of connected devices to 3-4.
  • Turn off background data transfer for apps (Settings → Apps → Permissions → Autostart).

If your phone still overheats:

1. Reduce screen brightness to 30-40%.
2. Turn it off NFC, GPS And Bluetooth (if you don't use it).
3. Switch to distribution via USB - this reduces the load on the Wi-Fi module.

⚠️ Attention: If the temperature exceeds 50°C and the phone starts shutting down spontaneously, this indicates a faulty thermal paste or battery. In this case, contact a service center—doing repairs yourself may void the warranty.
