Apple only recently released the iPhone 11 series to much acclaim in some regions and not so much in others. Now, reports have it that Apple’s latest operating system, iOS 13.1, is putting a 5W cap on some wireless chargers.

It appears that this issue affects both Apple-certified and non-certified wireless pads. According to reports though, it does not affect Qi wireless chargers from Anker, Belkin, and Mophie.

ChargerLab reports that with iOS 13.1, Apple only supports 7.5W wireless charging for pads that support fixed-frequency voltage regulation which Apple recommends.

What this means is that even the new iPhone 11 lineup tops out at 5W on chargers which delivered 7.5W on iOS 13. It is of note that the iPhone 11 lineup normally supports up to 10W fast wireless charging.

Apple brought 5W wireless charging to its 2017 lineup- the iPhone 8, iPhone 8 Plus, and iPhone X.

When the company released the iOS 11.2, those iPhone models could also enjoy faster 7.5W speeds. This was possible with Apple-certified Qi wireless chargers.

Now, this is not to say that the iPhone XS lineup and the iPhone 11 lineup cannot enjoy beyond 5W wireless charging. With the right wireless charging pad, you can get up to 10W.
