Does your iPhone overheat when charging, using navigation, taking photos or even just normal use? Slight heating is normal, especially when running heavy apps, updating the system or charging. But if your iPhone gets hot often, discharges quickly, slows down, or displays a temperature warning, it's a good idea not to underestimate the problem.
Why the iPhone overheats
The most common cause is a high phone load. Typically it's games, video, navigation, hotspot, long calls or apps running in the background. Your iPhone may also get hotter in direct sunlight, in the car, under a blanket or in a thick protective cover.
A common reason for this is a battery in poor condition. A worn out battery can discharge quickly, have a harder time holding power and get hotter when charging. A poor quality charger, damaged cable, clogged charging connector or a fault after a fall or contact with water can also cause problems.
Apple recommends that you normally use iPhone at an ambient temperature of 0 to 35°C. At higher temperatures, your phone may reduce performance, darken the display, suspend charging, or display a warning that it needs to cool down.
What to do if your iPhone gets hot
Let your phone cool down for a while, unplug it from the charger and remove the cover. Do not put it in the fridge or freezer! Check your battery in Settings, update iOS, and try turning off or uninstalling apps that drain your battery excessively.
If your iPhone overheats especially when charging, try a different quality cable and adapter. If the problem continues after that, the battery, connector or internal electronics may be at fault.
When is it time for service
We recommend servicing your iPhone if it overheats regularly, warms up even at rest, discharges quickly, shuts down, does not charge properly, or reports a battery problem. Professional diagnostics will quickly show if replacing the battery, cleaning the connector, or other repairs will help.
Overheating on your iPhone may not always be a serious problem, but it can reduce battery life and degrade your phone's performance in the long term. If you're unsure of the cause, it's best to have your iPhone checked before the problem gets worse.
