As temperatures soar past 30 degrees across Austria, it’s not just people who are feeling the strain. Smartphones, too, are reaching their limits — and overheating can cause lasting damage.
Why heat is dangerous for your phone
Modern smartphones — whether Apple or Android — are designed to operate best between 0 and 35 degrees Celsius. Once temperatures rise above that range, sensitive components begin to suffer.
The most vulnerable parts are the battery and the display. High heat can cause the battery to degrade faster, swell, or in extreme cases ignite. Displays may dim, discolor, or become unresponsive. Even tiny solder joints inside the device can soften or melt under prolonged heat exposure.
Samsung warns that “long-term use or storage above 35°C or below 0°C can negatively affect battery performance.” That’s a polite way of saying: heat ages your phone much faster than you think.
What you should avoid
- High‑performance apps — Games, navigation, camera use, and video editing push your processor to the limit and generate additional heat.
- Direct sunlight — Even a few minutes on a café table can send temperatures skyrocketing.
- Leaving your phone in the car — Parked vehicles can reach up to 70°C. Apple explicitly warns against this.
- Keeping it in your pocket — Your body heat adds to the problem, especially during summer activities.
What to do when your phone overheats
Most devices automatically reduce performance or dim the screen when they get too hot. If a warning message appears, it’s already serious.
Move the phone immediately to:
- Shade
- A cooler indoor space
- An air‑conditioned environment
Removing the case can help the device cool down faster. And if possible, switch it off entirely — nothing cools a phone more effectively.
What you should never do
Do not place your phone in the fridge or freezer. The sudden temperature shock can cause condensation damage inside the device, potentially destroying it for good.
