This sounds like this could be an absolute lifesaver if we’re a long, subway ride, where your earbuds die or in a desperate situation where you have a friend with battery at one percent. But how well does this actually work? Can you actually transfer a reasonable amount of power in a reasonable amount of time, or ultimately, is this just going to take too long and kill the battery of the power sharing phone? So I question that, and in this article I’ll be exploring the rate and efficiency of power sharing technology by testing it on many different devices.



Hey guys welcome back to the blog, I’m Michael Bryan and in this article we’ll be testing out the reverse wireless charging or power sharing of several different devices to see if it’s really feasible or practical in everyday life. And if you should actually care about this feature. When picking out a new phone, so starting off with what devices we’ll be using in this article, the charging devices I have, I have two of them I’ll be using the Galaxy S 10, regular and I’ll be using the Galaxy Note.

10.1. I will be using these two devices to charge several different devices in a set amount of time to see how much battery is lost on those and how much is gained on the other. Now the devices we will be charging are the Galaxy read active right here. We have the galaxy buds and then we also will be charging each other, so the galaxy s 10 and the galaxy note, n, plus and then just to have one device.

That’S not a Samsung device as an extra control right there. We will be using an iPhone 10 R or iPhone 10 s. Sorry also will be charging all these different devices for about 15 or 20 minutes I’ll have the timer set so that we can see exactly how much power is transferred and we’ll get a better idea of whether or not you can use this feature or how much Battery you can expect to gain and what amount of time and how much power you’ll lose from your original phone.

So, starting off with the galaxy s, 10 charging the iPhone 10 s on the iPhone we have 38 % and on the galaxy we have 57 % battery. Initially, after 20 minutes of charging, you end up with gaining 10 % on the iPhone, and you lost about 26 percent on the galaxy s 10. So that means in one hour you would gain 30 percent on your iPhone and it would cost you about 78 percent. On your galaxy s, 10, which seems very impractical for the amount of power you’re transferring and the amount of time you have to wait now if we do the same experiment with the Galaxy Note, 10.

1 and 80 % on the galaxy note, 10. 20 minutes we only gained 3 % on the iPhone and we lost 10 percent. On the galaxy note, n plus now, I believe. The reason for this is the placement of the phone. If you don’t have it perfectly placed on the back of the note 10 plus, then it might not charge effectively if you’re using something like the Galaxy read active. It will notify you of this, but the iPhone apparently did not and instead just charged very inefficiently.

So speaking of the galaxy read active charging, the galaxy read active with the galaxy note, 10.1 hundred percent on the phone and 2 % on the read 20 minutes later we gained 16 percent on the read and it only cost us 5 % on the phone so That means in one hour, which is a very long time to wait, but regardless one hour could give you 48 percent battery on your read, and it would cost you about 15 % battery on your phone.
