Apple has not provided specific details on why Android chargers may cause overheating, but it is possible that the different pin arrangements of the two interfaces could be a factor. Additionally, some Android chargers may not deliver the correct power output to iPhone 15 devices, which could also lead to overheating.
Apple recommends that iPhone 15 users only use chargers and cables that are certified by the company. This includes Apple's own chargers, as well as chargers from third-party manufacturers that have been certified by Apple.
Here are some tips for charging your iPhone 15 safely:
Use only chargers and cables that are certified by Apple.
Avoid using chargers that are damaged or worn.
Do not charge your iPhone 15 in a hot environment.
If your iPhone 15 starts to overheat, stop charging it immediately.
If you are concerned about the safety of your iPhone 15 charger, you can contact Apple support for assistance.
