There may be several reasons why the iPhone is hot while charging:
The phone's battery is aging and cannot be charged properly, causing the battery temperature to rise.
The mobile phone charger is not the original charger, and the voltage power is unstable, which causes the power management circuit inside the mobile phone to be abnormal and increases the heat generation.
Too many applications are opened in the background of the mobile phone, and the power consumption increases, resulting in the mobile phone motherboard, CPU, GPU and other components being in a high load state for a long time, and generating a large amount of heat energy.
Charging in the sun or the surrounding charging environment is too hot, which affects the heat dissipation of the mobile phone and causes the temperature to rise.
Charging while playing with the mobile phone makes the battery in a two-way use state of input and output, which increases the load of the battery and is easy to heat.
In order to avoid the charging of your Apple phone from getting hot, here are some measures you can take:
Use the original charger and charging cable, or use a third-party charger and charging cable that is certified by Apple.
Try not to use your phone while charging, or turn off unnecessary apps to reduce your phone's power consumption.
When charging, keep your phone in a cool, ventilated place, away from direct sunlight or near heat sources.
When charging, try not to use a phone case that is not conducive to heat dissipation, such as a phone case made of metal or silicone.
Do not turn on the wifi hotspot while charging, or try to minimize the time it is on.
Pay attention to the power of the phone when charging, and unplug the charger in time after it is fully charged to avoid overcharging.
Hopefully, these methods can help you solve the problem of hot charging on your iPhone.
