How iOS 13.1 Impacts Wireless Charging Speeds on iPhones
Discover how the iOS 13.1 update affects wireless charging performance on iPhones and which chargers maintain optimal speeds.
Wireless charging power has been reduced from 7.5W to 5W on certain iPhones running iOS 13.1.
The iPhone 11 and 11 Pro models support fast wireless charging, but with the release of iOS 13.1, not all chargers deliver the same performance. ChargerLAB conducted tests comparing wireless charging speeds on iPhone 11 models using the latest firmware against those running iOS 13.
The findings revealed that chargers rated for a maximum output of 7.5 watts are limited to just 5 watts after the update, leading to an increase in charging time by approximately 40 minutes.
Below is a graph illustrating the power, voltage, and current during wireless charging on an iPhone 11 with iOS 13:
And here is the same charger and phone combination with iOS 13.1 installed:
There is a silver lining: wireless chargers from brands like Belkin, Anker, Native Union, Logitech, and Mophie continue to support the full 7.5W charging speed even after updating to iOS 13.1. These chargers are available through official Apple stores and comply with the updated Qi charging voltage standards introduced last year. Essentially, Apple has intentionally slowed down charging speeds for older chargers to protect the device from potential damage.
