POWER SHARE BATTERY DRAIN TEST [How Fast Can it Charge a watch/earbuds/phone?]

by birtanpublished on August 23, 2020

So reverse wireless charging or power sharing has been creating a lot of excitement lately in the world of mobile devices and more and more phones are starting to include this feature which essentially allows you to take your phone and use it as a wireless charging

Pad to transfer power to your wireless earbuds to your SmartWatch or even to another phone that accepts wireless charging now at first 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 video 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 channel I'm Michael Bryan and in this video 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 video 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 watch 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 watch active it will notify you of this but the iPhone apparently did not and

Instead just charged very inefficiently so speaking of the galaxy watch active charging the galaxy watch active with the galaxy note 10.1 hundred percent on the phone and 2% on the watch 20 minutes later we gained 16 percent on the watch

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 watch and it would cost you about 15% battery on your phone this is

The first one that actually starts to seem practical because 48 percent battery on a small watch like this could potentially last you the rest of the day now charging the same watch on the galaxy s 10 we started out at 62% on the

Phone and 59% on the watch after 20 minutes it only brought us down to 55% on the phone and we went up to 77% on the watch this means in one hour you'd gain approximately 54% on the watch and it would cost you about 21% on your

Phone which again if you're sitting down somewhere and I work or something and you just your watch died and you forgot your charger this is a possible way that seems feasible to charge your battery for the rest of the day

So guys just a quick little sign here if you're new here and have not yet subscribed but you're interested in learning more about any of these devices in this video or more videos just like this one make sure you go down and click

The subscribe button and the Bell icon so you don't miss the latest videos so charging the galaxy buds with the galaxy s 10 now the phone starts at 49% the buds are at 20% and 5% and the cradle is in fact dead the buds have been sitting

In the cradle for about an hour now and this is all the juice they have left after 20 minutes they charged up to 30% in one year and 20% in the other and the phone only lost 4% bringing it down to 45% so we don't know if any power

Actually went into the cradle I'm just going to assume that most of it if not all of it went into the buds being that they're the end product I hope that's how the charging circuit works but regardless there is power in them now

And it was only 20 minutes so that's feasible next up charging the Galaxy Note 10 the calc cs10 so the S 10 starts at 67% and the note 10 starts at 2% so this would be an emergency situation with

Somebody and after 20 minutes we have 37 percent on the s 10 and only 10% on the Galaxy Note 10 so that means in one hour you could gain 24 percent but it cost you 90% now granted you can't actually lose 90% battery from wireless power

Share it caps you once you get to 70% lost or when your battery hits the 30 percent mark but so now flipping the experiment and leaving a case on the phone this time so we have a galaxy s 10 with the case being charged by the

Larger battery in the galaxy note 10% on the note 10 plus and 34% on the S 10 after 20 minutes we gained 10 percent on the S 10 and we lost 15 percent on the note so that means in one hour you could gain 30 percent in cost you forty five

Percent again one hour seems way too long to wait for 30 percent battery but you could potentially do this and this is probably the first matchup that really seems like it might be plausible so in conclusion wireless power sharing

Seems to be a very novel feature it seems like a really fun idea to have on a phone if you have peripheral devices such as watches or earbuds that would need to be charged wirelessly from your phone this could easily give you an

Extra day of battery on your watch or actually a couple extra hours on your earbuds now charging someone else's phone however seems to be a bit impractical being that you have to wait a very long time to gain any meaningful

Battery on the dead phone and then this will also cost you a very large chunk of battery on the charging phone so personally I don't think I will be using my phone to charge any other phones however if I'm on a subway and my

Earbuds die I may be using this to charge up and get a couple hours of music out of those earbuds so comment down below what you think about wireless power sharing do you think this is a feature that you must have on your phone

Do you think it's something that would be fun to have or do you think it is sort of a gimmick from the phone industry to just add more features to phones that may ultimately not even be used thank you all for watching I'll see

You next time
