Screen time varies by age group, but users between 16 and 64 are estimated to spend about six hours and 35 minutes a day on their devices, according to The Independent.
Given the high level of daily usage, it’s understandable why some people opt to charge their iPhones overnight to have a full battery for the next day.
However, Apple has issued a caution for iPhone users who do this, urging them to “use their common sense.”
In the “Important safety information for iPhone” memo on Apple’s website, the company advises mobile phone users to “avoid prolonged skin contact with the charging cable and connector when the charging cable is connected to a power source.”
This is due to the potential for physical injury or discomfort while users are asleep.
Additionally, Apple warns against sleeping or sitting on the charging cable or connector, noting that “sustained contact with warm surfaces for long periods of time may cause discomfort or injury.”
