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

Currently, on iOS 11.1.1, the three devices charge at 5 watts using Qi wireless chargers, but Apple promised that faster speeds would become available in a future update. It appears that update is iOS 11.2.


MacRumors received a tip about the new feature from accessory maker RAVpower this evening, 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.

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

With support for 7.5W charging speeds, the iPhone 8, 8 Plus, and iPhone X will be able to 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.

At 7.5 watts, Apple's wireless iPhones do not support the same wireless charging speeds that are available on some other Qi-based smartphones, as 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 noticeable improvements for iPhone 8, 8 Plus, and X owners.

Both the Mophie Wireless Charging Base and the Belkin Boost Up Wireless Charging Pad that are available from Apple support the faster 7.5W wireless charging speeds.

Several other Qi-based wireless charging accessories from other third-party manufacturers also support the higher speeds, such as the RAVpower Fast Wireless Charger, but there are accessories out there that don't, so you'll want to look for 7.5W charging speeds as a listed feature when making a purchase.

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

Has anyone tried charging with the cable and wireless pad at the same time? Out of curiosity

Not possible friend. Not even 9w. It's a hardware limitation.
Thank you bud

Maybe in future iPhones eh. Still 7.5w is better than 5w

There is also fast charging with the cable if you really need it to charge faster

Just tried it, the light on the wireless pad turns on and power is flowing but there's no new visual indicators on screen - my guess is that wireless takes priority and it shuts off the wired power, that's how most phones are.

Correct me if I’m wrong but this is still not anywhere near as fast as using the iPad charger, right? I mean it’s nice to have wireless charging and all but I still prefer the faster corded charging.

So I take it it doesn't charge even faster then? haha imagine charging at 22.5w :p

5W QI charger.
Haven't bought a Samsung QI charger before just didn't think they would ship with a 5w tbh

Do the iPhone 8 and X charge faster with the wireless charging if you put them in a microwave oven?
I was told once that microwave does destroy electronics! But I guess that is a myth.........

Can I ask, what is it with the racing to charge it as fast as possible? Don't most people charge their devices overnight?
