A new leak from China claims that the iPhone 13 will be able to support up to 25W of faster charging.
Currently the iPhone 12 is only capable of supporting 20W of fast charging even with a faster charging power adapter. The leak claims that Apple will also introduce a new 25W power adapter which will be the same as the current 20W, but will allow for faster charging speeds.
There won’t be a significant change to the charging speeds, but 25W is still better than 20W.
