Speed Test of iPhone 12 MagSafe Wireless Charger
Hi everyone, The new magsafe charger from Apple is something that a lot of people have questions about, one of the NO 1 questions I get asked is: what charger should I use with the USB-C plug? Today we will check and test the Magsafe Charge with different Adapters.
Whether you're using an Apple charger or not, I want to try and answer which one's the best. This Magsafe charger will charge up to 15 watts on the new iphone 12 series, so if you have an iphone 12, an iphone 12 pro like this, an iphone 12 mini or iphone 12 pro max, you'll get the most benefit out of it, because it will charge at 15 watts. Thanks to it , aligning right over the the charging coil properly, so you get the least loss of efficiency. So you've got a coil here, a coil inside the iphone and the magnets help align it, but depending on the charger you use makes a big difference.
Now this particular Magsafe charger is also compatible with any qi compatible device, it will charge with an older iphone, so an iphone 8 plus for example, I'll show that here and show you the charging speed, and then also any qi compatible phone from Apple or Android or any other device.
Let me go ahead and show you that and how I'm going to show you that is I have a meter here, this meter will actually measure the amount of power going through this meter, so we'll go from the charger to the meter, from the meter to the device, and it will tell us the voltage the, amperage and how many watts you're actually charging at.
DOES APPLE 5W CHARGE ADAPTER WORK WITH IPHONE 12 MagSafe?
Now, i have a bunch of different adapters here and right away we can get rid of two of them, because the non-pd power adapters are not really going to charge you any speed, meaning the usb-a adapter, which is the older five-watt charger from apple, it really doesn't charge at any speed. And also the samsung adapter that's USB-C, or USB-A to USB-C or whatever you choose to use it with so, neither of these really are worth even trying they charge about half a watt, so i'll show you some of that in a moment. but let's first try a standard test where we'll use the new 20 watt adapter that apple recommends to use with magsafe, now you can charge it 20 watts using this USB-C to lightning or 15 watt using magsafe adapter.
OUTPUT OF IPHONE 12 BY APPLE 20W PD CHARGER(C-Lighting)
So first let me show you how this works at 20 watts. we'll plug it in here, we'll take USB-C to the top of the adapter here or the meter here. and then we'll take this and plug in a USB-C to lightning cable. We'll plug it in here, and depending on the charge state of your phone will make a difference. as far as how fast it charges, you'll see them at 46% when we get above 80%, it will slow down. so let's plug it in here, you'll see it's charging now. the meter turns on and immediately in the bottom right, you can actually see how much power it's drawing, it takes a moment and now we're up to about 19 to 20 watts right away.

So this will show us exactly how much power is being brought through this charge cable all the way over to the iphone, now let's go ahead and try it with the Magsafe, so the same thing here will plug magsafe into the bottom of the meter, place the phone, let's go back to the home screen, place the phone on the magsafe wireless charging adapter, it auto aligns itself and sometimes to get the meter to turn on, you just need to flip the cable, we'll do it there. it's turning on and now it's charging the iphone 12 pro, now we'll take a moment for the wireless charger to actually negotiate and then get the higher power output, so we'll give it a minute, here you'll see it's ramping up, it went from five watts to seven, then to eight to nine and it will take a little bit of time to get up to 15 watts, And the actual temperature makes a difference as well. if the phone is too hot, it will not hit 15 watts, i've placed it or i've run a few tests rather and found that, if the phone is really warm, it keeps it down below 10 watts, so we'll give it a minute, usually it takes 30 seconds to 60 seconds to ramp up to 15 watts, i'll give it a moment and i'll show you that, now it took a minute or so, but you'll see we're at about 15 watts 14 .5 watts, so it's at its full speed and it will go 15 watts, it'll bounce back down and then go back above it, but in general we can get 15 watts of charging out of the 20 watt adapter, through this to the iphone and it will show us that it's charging now, as you ramp up to about 80% charge, it will slow back down
OUTPUT OF IPHONE 12 BY MagSafe WIRELESS CHARGER AND APPLE 18W CHARGER
Now let's test out the 18 watt adapter, so we'll do the same thing here, swap over to the 18 watt adapter and plug it in, we'll charge and it will take a moment to connect, and then it will start ramping up the power, so it takes a moment, and i don't know exactly how accurate this meter is, but it seems to be okay, it's measuring all of the throughput of this power, it's pretty simple and seems to be hitting the 20 watts when you're using a 20 watt adapter to lightning, but you'll see the 18 watt adapter is now at 9 watts , and in testing this, i've seen it go as high as 13, but it does take some time to actually ramp up to that speed, but so far the 20 watt actually is pushing out the most amount of power so far, so you'll see we're at 11 watts takes a little bit more time, and i don't know that we'll get much more out of it than that, so the 20 watt is a little bit faster than the 18 watt which you might expect, maybe we have a little bit of loss due to the wireless charging,
OUTPUT OF IPHONE 12 CHARGED BY APPLE 65W PD AND MagSafe WIRELESS CHARGER
Now let's try the macbook charger, so if we swap over to the macbook charger, this is the 96 watt macbook charger from the 16 inch macbook pro, so if we plug this in, do the same thing here, you would expect that this should be able to hit 15 watts, no problem, but if it doesn't have the pd profile for this particular device or to be able to handle 15 watts, it may not work properly. but again let's give it a minute and see what it gets up to. now what i've found in my testing is. you'll see here, we're still charging, we'll get to about 10 watts and then it will stop. The macbook charger doesn't seem to want to go over that, so the phone is drawing 10 watts of power and that's as high as i've ever seen it go with th macbook charger, so i really don't see any reason to use a macbook charger unless you're in a pinch or you don't have the 20 watt adapter.
OUTPUT OF IPHONE 12 BY ANKER PD AND MagSafe WIRELESS CHARGER
Now let's try some third-party adapters as well, so we have the power port atom pd1 from Anker, let's go ahead and plug this in again, it's the same sort of setup, plugit in and it will start charging the phone, you'll see it's charging and even though we're over 50, it doesn't really bring that down until about 80. That's the charge profile it seems, so you'll see, we're at about nine watts of power, so it is working okay. but i do see this sometimes drop down to one watt and start charging all over again, so i'm not sure why that happens but you'll see it's sitting between seven and a half to ten watts with this this pd1 charger from Anker.
OUTPUT OF IPHONE 12 MagSafe WIRELESS CHARGER BY AUKEY PD CHARGER
Let's try the Aukey charger as well, this is a 65 watt capable charger, so we'll go ahead and plug it in. i've given it some time before i've never seen it go above about 10 watts with the Anker's charger, we'll plug in the Aukey's charger same thing here， again we're getting a similar sort of charging profile from this charger, the Auky charger, even though it's capable of 65 watts, it's not pushing out the capable 15 watts that the magsafe is capable of, so i'm seeing this over and over in different devices, so you'll see here we're at 9 watts and it usually hangs around that amount of power even if you let it sit for quite some time.
OUTPUT OF IPHONE 12 MagSafe WIRELESS CHARGER WITH PIXEL 4 ADAPTER
Now if we switch over to the pixel charger, this is the charger that comes with a pixel four or five, so maybe you're switching to an iphone, you have that USB-C charger, there we go. we're charging and you'll see what we get. this one is a little bit more surprising i think. in my tests usually it hangs around seven and a half watts, even though it's capable of more and again it's bouncing back and forth to nine, so we're getting basically the same experience as we did with the third party chargers, but not up to 15 watts again. So you'll see it takes just a moment and it usually like, I said stays around 7.5w. We're not getting the same power output as we did with the 20 watt charger 。
OUTPUT OF IPHONE 12 MagSafe WIRELESS CHARGER WITH SAMSUNG NOTE 20 PD
If we move over to the samsung charger. this is the charger that comes with the Samsung galaxy note 20 ultra, so you can see the charger here again, plug it in, plug in the same connector here, we're charging again and we'll see if it ramps up. so it takes a moment and again we're getting a similar experience as we are with all the third-party chargers, so we're at 7 watts and then we're bouncing back and forth between 6 and 7 watts with this samsung charger even though it's capable of more, so a lot of that could be with the power profile that's attached to the charger itself, but we're really not getting phenomenal charging speeds with any of them, except for the 20 watt apple charger.
OUTPUT OF MagSafe WIRELESS CHARGER BY APPLE 5W ADAPTER
Then finally for those that are curious, we have the 5 watt adapter, adapted with USB-A to USB-C, then to magsafe, so we'll plug it in here, and you'll see it's only going to give us about half a watt, it sits at about half a watt, so i wouldn't recommend charging with it. it's just going to sort of flash here, and not work properly. you get the same experience with the samsung USB-A charger as well.
OUTPUT OF IPHONE 11 PRO MAX + MagSafe WIRELESS CHARGER + APPLE 20W PD
So we'll switch back to the 20 watt adapter since we know it works best. we'll plug that in plug it in again, plug it into our meter now other than with iphone 12, let's see what it charges an iphone 8 plus and 11 pro max at. Since those are not the same magsafe devices, but they do have qi wireless charging, so let's go ahead and we'll take the 11 pro max, place the charger on the back, you'll see in the upper right it's charging and let's see what the meter does, so we're getting close to about 5w. now many people think this charge is at about 7.5w, so we'll see if we reach that. we'll give it a minute or so and see if we ramp up above 5 watts, and after we've waited for a little bit of time, you'll see we're still at 5 watts, so you're not really going to be charging the iphone 11 pro max very fast with this, but you will get what you would with the 5 watt charger.
OUTPUT OF IPHONE 8 P+ MagSafe WIRELESS CHARGER + APPLE 20W PD
Then again, i have an iphone 8 plus and the iphone 8 plus is at 80% of charge, so it's pretty low on charge and we're already at about five watts of charging, so you definitely can charge an iphone 8 plus with it but we're not getting very fast speeds. so i did hit six watts there for a second but don't expect fast speeds with this charger on anything but the 12. It seems at least in these tests.
So, you'll see, apple does say it can hit 7.5W and maybe if we leave it for a little bit it will, but you'll see the wattage going up and down, we're hitting six and it's going back and forth, so between 5-7 watts with this charger at least from what this meter says.
OUTPUT OF Pixel 4 + MagSafe WIRELESS CHARGER + APPLE 20W PD
Now let's swap over to a pixel 4 xl which this is a wireless compatible phone, put the magsafe in the back and since they all use coils, it should charge okay, you'll see here in the upper right it's at 65 and it's charging, you've got the little charge symbol but we're at 1.5 watts, so it's not charging very fast. and let's move this around, maybe a little bit on the back, maybe we can get a little bit better connection here, if we slide it up that seems to be about a watt and a half in the best place.So it's not the best with third-party devices, so if you were thinking of getting one of these for an android phone, well so far it doesn't seem to be doing that well.
OUTPUT OF IPHONE 12 MagSafe WIRELESS CHARGER + APPLE 20W PD + CLEAR CASE
Now many want to know how fast can we charge with a third-party case, so let's try a third-party case and then we'll try a magsafe case as well.
So this is a third-party case and it will adhere just like that magnetically it aligns, it's charging. we'll give it a minute to ramp up and let's see what kind of speed we can hit. so it looks like we're going to get the full charge power out of this, using a third-party case. we're at 16 watts which was actually better than when it was adhered directly to the back, so 16 watts or so 15 16 watts at least from this test.
OUTPUT OF IPHONE 12 MagSafe WIRELESS CHARGER + APPLE 20W PD + MagSafe CASE
Now let's try a magsafe case so we'll take this case off, you can see this one is by case cue, so i'll link that below if you want to see that, so here's our magsafe case, you can see that by the ring inside for the magnets, we'll just put it in place here, there we go we hear a sound that the case is connected, and we've got our magsafe adapter on the back, it's charging now. and let's see what we ramp up to. Now the interesting thing with the magsafe case is, i'm getting about 13.5 watts now, that may be because it's getting a little bit warm , i can actually feel some heat in the top of the case, so why don't i let it cool down for a moment and we'll see what it's like, and see if we can get any faster speeds. I've let it run for about a minute and we're bouncing around 13 watts or 13.5 watts as far as the power, so let me cool this down and then we'll see what it charges at now. i gave the phone a couple minutes to cool down, so it's not hot to the touch anymore and i put the connector back on the back, so let's see what we ramp up to. Now that it's cooled down and see if it makes a difference. so now that the phone is cooled down with the case, you'll see that it's charging at 15 watts, we're getting full power but apple seems to be very aggressive in reducing that power based on the actual temperature, so the charging curve you'll see, we've actually hit 16 watts. So it's very dependent on temperature,
so in conclusion what i would say is, at this point, we know that the 20 watt adapter seems to be the best experience for the fastest charging, that's why i suspect they switch from the 18 watt to the 20w, although I haven't confirmed this, but that makes sense. so that we can have the extra power for wireless charging with magsafe.
And also in conclusion i would say that, if you want the best experience for the longest fastest charge, i would remove the case and then put the charger on there , it can dissipate the heat more easily. now maybe you're getting about the same experience with a case, but if it does start to warm up, the power will go down slightly until it can cool down and it really depends on your ambient environment, here it's about 70 degrees fahrenheit, so that's the temperature i'm testing this in, and then also the chargers that i've used for testing so far。 the other day i charged from seven percent to 100, using the macbook charger, thinking i would get the best experience and it took over about three hours and 20 minutes or so to charge it. It's much faster using the 20 watt adapter because it can keep the power up to 15 watts with its pd profile.
So keep that in mind, if you are going to charge fast charging, i would pick up the 20 watt adapter from apple. This seems to be the only one that i'm getting a full 15 watt charge from, at least in this meters testing experience. So definitely you get the 20 watt if you have it, this comes with the latest ipad air, it also comes with the 2020 ipad. so make sure you have the 20 watt, i think it's about 20 dollars.
Of course you can use any of the others i mentioned, but you just won't get the fastest speed it seems like. And again you can use it with older devices as well, it will work but just not as fast. So you will need a magsafe capable device to get that full speed.
Now let me know what you think of magsafe. are you using it with an iphone 12? Or will you be if you're picking up one of the other models as well?
