    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.

    Great news. Hopefully we’ll see even better things in 2018 as Apple augments the Qi standard.

    Glad to hear it’s coming and glad to hear they took their time. When it comes to charging and batteries... rushed products can have explosive effects.

    Good news for all that have the latest models. Apple will really push wireless charging going forward which is good for the industry as a whole.

    Do the iPhone 8 and X charge faster with the wireless charging if you put them in a microwave oven?

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

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

    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

    What's the point of wireless charging if it requires additional hardware, charges at half the speed of a conventional charger, and still requires you to place your phone in a specific location like a normal cable?

    Someone sell me on this.

    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.

    No, using the iPad charger is still faster.

    Hope you guys will do a side by side between the faster wireless charging and the iPad charger (which I think is the better option compared to the usbC because of cost and only marginal improvement when moving up to the usbC).

    I am usually not in a rush to quickly charge it as I place it on a mat before I go to bed but this is welcome update.

    Sure, it's something we can look into and potentially write about.

    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?

    Yes, I'm thinking maybe a comparison of 7.5W wireless charging, charging with the 5W iPhone adapter, charging with the iPad adapter, and then charging with the USB-C to Lightning cable and a MacBook adapter.
