How does phone power sharing work?

So imagine this: you got a hot date who’s hanging onto your every word and she’s, asking you what’s next on the docket for the evening, you bust out your phone to get directions to an incredibly Romantic used article game shop and suddenly you notice it’s better than your last relationship.

You start to panic, but suddenly your date pulls out her phone holds it against yours and what you initially think is some kind of weird courtship ritual, but then you see that your phone is working again thanks to wireless power sharing.

So you immediately have two thoughts. One she’s, a keeper and two howden. The heck. Does wireless power sharing work? Well, we explained the basic principle behind wireless charging in general, in our previous article on distance charging, which you can check out up here.

But the idea is that when you run a current through a coil of wire and bring it close to another coil of wire, a physical phenomenon called electromagnetic induction, induces a current in the second coil.

This is how regular wireless chargers work, including the relatively common qi, chargers and even electric toothbrushes, but what makes wireless power sharing different, so the biggest difference is that your phone ends up charging another device directly from its main battery.

Up until now, traditional wireless charging has used a base station that’s plugged into a wall outlet or it’s taken the form of a wireless battery bank. The advantage to wireless power sharing is that you, don’t need any extra equipment like an external charger or power bank and the phone itself doesn’t even have to be any larger.

It simply uses a small induction, coil built into the phone’s body, currently, the most well-known phone that features this technology is the samsung galaxy s 10, which cannot only power up the company’s, galaxy watch and galaxy buds, but also Any other phone that supports Qi charging now, reportedly the recently launched iPhone 11 lineup, also contains the hardware to support wireless power sharing, but Apple has disabled the feature for now for reasons that aren’t totally clear.

Perhaps the performance wasn’t up to scratch. Indeed, wireless power sharing does come at a rather steep energy cost. In a best-case scenario, current technology will provide around 500 million of Kuran, which isn’t all that much.

So if you’re trying to charge a smartphone with a 3500 milliamp hour battery, that means it would take roughly three and a half hours just to get the charge up to 50 %. However, the galaxy s 10 reportedly loses around one quarter of its battery life for every hour that it has wireless power sharing enabled so you shouldn’t expect to get anywhere even close to fully charging another phone anyway, wireless power sharing is pretty inefficient In that, less than half of the power used up by one battery will wind up in the other battery.

So right now the technology is best suited for quick top ups. When you need a second phone to just work for a short period of time or if you’re charging up less power-hungry devices like smart watches, however, as phone battery technology progresses, we may end up seeing more robust wireless power sharing solutions.

For now it’s, a good way to keep you going in a pinch, so you can think of it as like. An energy drink for your phone that hopefully won’t, give it the jitters half an hour later. Speaking of half an hour later, don’t.
