iOS 11.2 Supports Faster 7.5W Charging On iPhone X, iPhone 8, iPhone 8 Plus From Qi-Based Wireless Accessories

Starting with the public release of iOS 11.2, the iPhone 8, iPhone 8 Plus, and the iPhone X are able to charge at 7.5 watts using compatible Qi-based wireless charging accessories.

In fact, Apple will introduce faster 7.5W wireless charging for all the three new iPhone X, 8 and 8 Plus handsets. Currently, on iOS 11.1.1, the devices charge at 5 watts using Qi wireless chargers, but Apple promised that faster speeds would become available in a future update. It appears to be the final iOS 11.2 firmware.

Wireless charging has already been supported out of the box with those devices via Qi-compatible charging pods and stands. With the iOS 11.2 public consumption, owners of those devices will literally be able to get a charge into their device much quicker with the unlocking of faster charging.

A tip about the new feature from accessory maker RAVpower has been received and tested the new charging speeds to confirm. Using the Belkin charger that Apple sells, which does support 7.5W charging speeds, the iPhone X was charged from 46 to 66 percent over the course of thirty minutes, according to MacRumors.

The same iPhone charged from 46% to 60% over 30 minutes when using a wireless charging accessory that does not offer 7.5W charging speeds. These tests were intended to emulate real-world conditions, with a case on and Airplane Mode not activated.

iOS 11.2 Beta 3 Enables 7.5W Fast Wireless Charging

We now know that 7.5-watt charging will be unlocked for those three compatible devices with the public release of iOS 11.2, which is somewhat in a beta state with developers and registered testers. With support for 7.5W charging speeds, all the compatible iPhone 8, 8 Plus, and the OLED iPhone X will be able to first charge more quickly over a wireless connection. And it appears 7.5W wireless charging speeds are faster than the speeds you get with the standard wired 5W power adapter.

Note: At 7.5 watts, Apple’s own wireless iPhones do not support the same wireless charging speeds that are available on some other Qi-based smartphones. Because the current Qi 1.2 standard allows for up to 15W of wireless charging power. Still, 7.5 watts is better than 5 watts and should offer some essential improvements for iPhone 8, 8 Plus and X owners.

Apple didn’t make this information known in any release notes. But testing of the theory has confirmed that iOS 11.2 does support 7.5W charging after a well-known accessory manufacturer revealed. One of the most interesting things is that Apple’s wireless charging devices are not compatible with the full capability of the Qi standard.

Several other Qi-based wireless charging accessories from other third-party makers also support the higher speeds. Take a look at the RAVpower Fast Wireless Charger, but there are accessories out there that don’t. You’ll want to look at for 7.5W charging speeds as a listed feature when making a purchase. Both the Mophie Wireless Charging Base and the Belkin Boost Up Wireless Charging Pad are now available from Apple to support the faster 7.5W wireless charging speeds.

iOS 11.2 is limited to developers and public beta testers at this time. And we’re on the third beta, a public release could come in a few weeks to a month.
