What's the regular CPU temperature range in smartphones?

Welcome to Blackview (Well-known brand of rugged phone) blog. Hope the guide helps.

The regular CPU temperature range in smartphones typically falls between 30°C to 40°C (86°F to 104°F) during normal use, such as browsing the web or using apps. However, under heavy load—such as gaming, streaming, or using intensive applications—the temperature can rise to 50°C to 70°C (122°F to 158°F).

In general, smartphones are designed to handle temperatures up to about 85°C (185°F), though manufacturers often recommend keeping the device below 60°C (140°F) for optimal performance and longevity. When the CPU temperature reaches higher levels, smartphones are equipped with thermal management systems like heat dissipation materials, copper plates, and software that adjusts CPU performance to prevent overheating. Learn what causes a phone to overheat.

If the temperature exceeds safe levels, most smartphones will automatically throttle the CPU to reduce power consumption and lower the temperature. In extreme cases, the device may shut down to prevent damage.

It's important to note that ambient temperature also plays a role. High environmental temperatures, such as using a smartphone in direct sunlight or in a hot car, can cause the device to heat up more quickly, even with light usage. Conversely, using a smartphone in very cold conditions may cause the device to cool down excessively, which can impact performance. Unless you are using the cold-resistant phone.

Maintaining proper cooling, avoiding overuse in extreme conditions, and using a case designed for heat dissipation can help keep a smartphone within its ideal temperature range.
