iOS 11.2 will allow your iPhone to charge faster wirelessly: 7.5W of Qi goodness

According to a tip revealed by accessory maker RAVpower, the upcoming official release iOS 11.2 will be the software update that will unlock faster wireless charging for the iPhone 8, 8 Plus, and iPhone X. It looks like the feature is already part and parcel of the iOS 11.2 beta, which is available to developers and adventurous folk alike, and is enabling all three iOS devices to get topped up by at 7.5W by compatible Qi wireless chargers.

As a reminder, all new iPhones support wireless charging, but as of iOS 11.1.1, which is the latest official software, only 5W Qi wireless chargers are supported. Although the added support for 7.5W Qi charging won't introduce a dramatically quicker wireless charging experience, the evidence points out that users should expect marginally improved charging speeds. 

As MacRumors points out, an iPhone X running the iOS 11.2 beta got charged from 46% to 66% by a 7.5W Belkin wireless charger in about 30 minutes. Using a non-7.5W wireless charger topped the same iPhone X from 46% to 60% in over 30 minutes, which speaks of marginal gains here and there, but gains nonetheless.

Still, that ramp up to 7.5W is barely touching the current limits of the Qi wireless charging technology, which allows for up to 15W of power to be transmitted to compatible devices. Needless to say this charges their batteries faster and is overall a user-friendly trait that Apple will likely catch up on sometime in the future provided that the hardware inside the all-new trio of 2017 iPhones allows it. No one wants another Note 7 debacle, especially when a $1,000 animoji machine is involved.

No word when iOS 11.2 is coming along to an iPhone near you, but it shouldn't take long.

You talking about wireless charging for iPhone yet you mention note 7 here? What's the relevance of a note doing in this article?

The max for wireless charging is 15W but Apple only raised it from 5W to 7.5W, charging causes the battery to heat up and most Note 7's caught fire while on the charger or soon after being taken off. The author is just saying that Apple has gone the safe route with their charging speed by not cranking it to 15W, perhaps because Apple doesn't want the phones becoming to hot and potentially catching fire, after all plenty of iPhones have caught fire in the past and Apple hasn't used any form of quick charging until this year, Apple obviously wouldn't want their first attempt to turn into the iPhone version of the Note 7 fiasco.

Although number of iPhones have caught on fire before which are not related to wireless charging there hasn't been a single catastrophic even just like Note 7 recall where all those battery related features played a major role in it's battery to blow up drama including fast wireless charging. Any kind of fast charging makes the battery heat up pretty badly and thus degrades the safety and life span of the battery.

Maybe maybe not but I think his point is valid. They might be taking it slow so they don’t have problems with overheating the battery until they perfect the thing. Like Samsung should have perfected the more 7 battery before releasing it.

It is hard to catch fire when the phone comes with a weak 1A charger that takes 3h to recharged the device...

Because that's the best example for "not to f**k up with the phone battery" kind of situation. Samsung enabled all the features in the world but couldn't end up making a safely usable smartphone at the end. So what's the use of all those gimmicky fast charging and s**t??? It was an embarrassment in the end. Apple better not play with the electricity just like them and I'm more than happy with 7.5W wireless charging for now.

Have a qi receiver on 6s plus and seems like it charges faster then 5w. Maybe not. Does pretty good. Rather have built in so I can go to the wire when needed. I use fast charge wireless pads for future proof anyways.

7.5 Watt is still pretty paltry when you take efficiency losses into account. Based on the numbers quoted, the efficiency with the Belkin charger came down to 72%, or 5.4W effectively when charging in the fastest range of the battery (between 15 and 85%, much slower outside that range). We're still talking about roughly 3 hours to charge from 0 to 100%.

Peter, There is no such thing as wireless charging. That little cord from the wall to the charger is called a cord. You need to reword your headline and story as it’s 100% misleading and false.

Yes there is. If you go back befor the plug there is wires to but we are talking getting away with not plugging wires into your phone. It’s a step away from having it charg in your hand wile using it from a couple feet away. Now atliest you won’t have to worry about a broken charging tip or a dirty charge port to charge it.
