Warning: iPhone can overheat for a variety of reasons, both during normal use and in situations that may indicate a problem. Here are the most common causes of an overheating iPhone:
1. Intensive usage
* Games and applications requiring high processing power, as well as some websites – long gaming sessions or using graphics-intensive apps can cause device heating.
* Recording and editing video in high resolution – processor and graphics card work at high speeds.
* Multitasking – running multiple apps in the background can increase processor load.
2. High ambient temperature
* iPhone may overheat when used on a hot day, in the sun or in a car. The device may display a heat warning message and automatically shut down to prevent damage.
3. Charging the device
* Fast charging – using high-power chargers (e.g. 20W or more) generates more heat.
* Non-original chargers and cables – low-quality accessories can cause excessive battery heating.
* Charging in a thick case – if iPhone is charged in a bulky case, heat may not be able to dissipate.
4. System and application issues
* iOS system errors – some updates may contain bugs causing higher processor usage.
* Apps running in the background – some apps can run in the background and consume many resources even when not in use.
* Data synchronization – first hours after updating iOS or restoring from a backup can cause increased system activity.
5. Hardware problems
* Damaged battery – if the battery is worn out or damaged, it may overheat.
* Cooling system issues – iPhone does not have fans, so cooling occurs passively. If the device overheats without an obvious reason, it may indicate a hardware problem.
How to prevent iPhone from overheating?
Avoid using your phone in direct sunlight. Don’t use demanding apps for a long time without a break. Limit the number of background apps. Use original or certified chargers. Turn off Bluetooth, GPS and 5G when not needed. If your iPhone is hot, put it aside and let it cool down.
If your phone overheats excessively without an obvious reason, it may indicate a hardware problem and you should contact Apple’s service.
