World is experiencing one of its hottest summers, with temperatures soaring past 50 degrees Celsius in many regions. Among them is India, where New Delhi recently recorded a staggering 52 degrees Celsius. Such extreme heat affects not only our bodies but also everyday items, particularly our smartphones.

Pivotal in today’s world, smartphones can overheat for various reasons, from high-processor games to fast charging. When exposed to extreme temperatures like 50 degrees Celsius, these devices can malfunction. Smartphones typically operate best between 0 and 35 degrees Celsius. Exceeding this range can cause the device to slow down, freeze, or even shut down. Fortunately, most smartphones are equipped with built-in thermal sensors designed to cool them down.

Research has shown that prolonged exposure to high temperatures can reduce a smartphone’s lifespan. According to Asurion, a US-based phone insurance provider, there was a 15% increase in battery-related issues during last summer compared to the rest of the year, as reported by Bloomberg.

With many countries facing even harsher summers this year, it’s crucial to know how to keep your smartphone cool.

Why Do Smartphones Overheat?

Smartphones can heat up due to several factors, including exposure to high temperatures, heavy gaming, and fast charging. The increased charging speeds today mean more power flows through the device at a given time, causing it to heat up quickly. Last summer, many phones on the Italian island of Sardinia experienced issues during Europe’s heatwave. Tom Paton, founder of Green Smartphones, an online phone comparison platform, told Bloomberg that problems typically arise when ambient temperatures reach 43 degrees Celsius or higher, especially if the device is in direct sunlight.

Tips to Protect Smartphones During a Heatwave

  1. Avoid Direct Sunlight: Keep your phone out of direct sunlight to maintain an ideal temperature. If you’re outside on a sunny day, lower the brightness to help keep the device cooler.
  2. Use Breathable Phone Cases: Standard phone covers can trap heat. Consider using cases designed with breathable materials and increased airflow to help dissipate heat more effectively.
  3. Charge in Cool Environments: Charge your phone in a cooler environment to prevent overheating. Avoid using the phone while it’s charging, and if necessary, remove it from the charger.
  4. Natural Cooling: Allow your phone to cool down naturally. Avoid abrupt temperature changes, like putting your phone in the refrigerator, as this can cause damage.
