Reverse wireless charging has been a big selling point in phones for the last couple years. It's almost a staple in any current top-shelf phone, and for good reason; it's convenient. Regular wireless charging is even more common at this point.
But it might become a little more widespread soon, thanks to a new certification that will allow reverse wireless charging over NFC.
Wireless charging via NFC
This new certification is good news, but there's a catch. This standard will only allow up to 1W charging, which is honestly really slow. Your typical reverse wireless charging isn't even that slow, which means this news isn't going to do much for phones on the horizon.
But it does open the door to smaller devices, like earbuds, watches, and IoT gadgets to pick up wireless charging. You might still prefer a quicker wireless charging speed that you'll get out of Samsung Galaxy Buds, for example, but cheaper headphones could potentially get by with the 1W charging. Location trackers and other things will also benefit here.
It also opens the door for manufacturers to use NFC for their wireless charging protocols to save space in devices, and if this tech continues to grow there's a chance we'll see big improvements over the next few years. You can't do fast charging via NFC right now, but in a couple years? It might be a thing.
Oh, but don't expect this to get backported to older phones, even if they have NFC. It'll have to be a new implementation.
