First Why do smartphones heat up? according to https://www.androidpit.com/phone-overheating, the answer lies in a basic property of physics: movement generates heat. The amount of heat your smartphone produces is largely proportional to the amount of electricity moving through it. If you’re playing a game that demands a lot from your central and graphics processing units, both housed in a central system-on-a-chip (SoC), they will become warm, as they require more power to carry out their tasks.
How to avoid overheating
To manage or prevent overheating of the SoC, ensure you don’t play demanding games or watch videos for too long, don’t multitask on applications that require a lot of processing power, try to avoid using Bluetooth for prolonged periods, and only use Wi-Fi if its stable. In essence, avoid as many demanding processes as possible.
