Hello, I'm Apple Daddy
Today I am going to share my test of wireless charger
We know that in Apple's new iOS 13.3 update
Support for third-party fast wireless charging is now available
Of course, the fast charging we are referring to is still only 7.5w.
So I will test three different wireless chargers here
Before you start, please remember to subscribe and like to share my videos.
And also remember to like it on Apple Daddy's Facebook fan page
Any more lucky draws will be posted on it
The first one is of course the control group.
Apple officially has a Mophie wireless charging pad on sale
This one has official 7.5w fast charge support
The second one is to buy it from a merchant
And determined to be the original authentic Bestus Baseus wireless charger
This one is also specially designed for Apple (but unofficial certification)
He even used the charging cable and connector inside for Apple.
This one can support 5w and 10w, and there is a special design
Is that there is an LED wattage display on his charging pad
The third one here is Xiaomi's 10w fast charge
Compared to the 20w one
The evaluation on the Internet is that this one can support Apple 7.5w fast charge
Of course, this is also impossible after the previous iOS 13.1
So I also bought to test whether the fast charge can be restored after this update.
In the part of the charging head, Mophie can only use his own charging head
The other two I will use this Xiaomi to support up to 27w
And there are USB-A and USB-C charging heads
In terms of test current, here is a measure of the wattage coming out of the charging head.
The other is to test the w number of wireless charging output and the stability.
Finally, of course, there is a thermometer. I will charge it for a period of time.
Test the temperature of the center of the charger separately
That's about it. Now let's share the results of the charging test.
So at first I compared
IPhone 11 Pro Max with iOS 13.3
And iPhone X with iOS 13.2
Of course, the two batteries have different capacities, so you cannot compare the charging speed.
But we can look at it from the amount of current
iPhone 11 Pro Max puts on Basel charger
Can start fast charging
Because on the side of current wattage, it came to about 10w
However, the iPhone X has been stopped between 5.5 and 6.7w.
To determine if this is the effect of the iOS version
I compared the charging speed before and after the iPhone X update
Because the battery capacity is relatively small, it does not take too long to do the charging test.
The table above can see the performance of iPhone X iOS 13.2 under various chargers
Only Mophie's went from 48% to 57% in 10 minutes
The other two models only charge to 53%
But in the temperature part, Mophie is also relatively high.
Let's take a look at the table below
This is how the iPhone X is updated to iOS 13.3
Mophie is only 56% this time, but I think it ’s the average error.
The other two have reached the same level
And it's slightly lower in temperature
Let's measure the wattage of the charging head.
You can see that the iPhone X can also reach 9 ~ 10 watts.
Prove that it was really limited by the iOS version
I used iPhone 11 Pro Max again to test (charger)
It's strange that Xiaomi performed poorly in this test
So I tested it several times after installing the current tester.
Found that it would always bounce between 5v and 9v
The amperage part is also very unstable.
As if detecting the end can use that charge
If detected, 9v (10w) fast charge will be used to continue charging
If you keep beating repeatedly, you will eventually stop charging
It seems that Xiaomi charger is still a bit unstable for Apple.
You can't blame Xiaomi, after all, it was not made for Apple.
Come again with this wireless charger monitor
Can individually detect whether there are wireless charging standards that pass 5 / 7.5 / 10w
As a result, Mophie's test passed 5 times.
Basel this model can only pass 5w, others have failed
Xiaomi's all passed, so it means it's not of bad quality
It ’s just not completely compatible with Apple products.
But to mention a little Xiaomi's 27w charging head
High compatibility with other brands of wireless chargers
When I use this charging head to connect with the wireless charger from Best, it will jump out 9v immediately.
Whether connecting to USB-A or USB-C, please note that only one connector can be used at a time
If the other one is connected, the other device will jump back to 5v even if it is not charged.
In contrast, Apple's own 18w USB-C or other brands of 18w charging heads
I still stop at 5v most of the time. I do n’t know why.
But if you want to connect a wireless charger, this charging head of Xiaomi is quite recommended to use it
So today ’s first conclusion is
iOS 13.3 is really unlocked, allowing third-party wireless charging to reach 7.5w again
However, the compatibility of third-party wireless chargers with the iPhone will also affect its charging quality.
The second conclusion is
Although Apple's official certification of wireless charging is a bit expensive
But it is really the most stable one
Especially if you want to charge your iPhone
But the temperature is still high
This will affect the long-term charging rate and battery life.
So I might want to come again to find if the quality is close to the original
Compatible with iPhone and good heat dissipation
May look for models with active fan cooling
The third conclusion is that when the 7.5w fast charge is started
After the comparison test, if the output of the charging head is more than 9w
To the wireless charging end is about 6.1-6.5w left
So the general understanding is that wireless will lose about 1/3 of it.
So although it is 7.5w, it is actually 6w left on the phone.
Of course, it is almost twice as fast as 5w (wireless charging will save about 3.3w)
But it is still far from the 18w that can be supported by the current cable.
Wireless charging is currently for convenience
Or you can let him recharge slowly while sleeping and at work
But also pay attention to temperature
Long-term overheating is very bad for battery life
I hope to do more tests on wireless charging in the future
If you have any suggestions or if the manufacturer wants to provide tests, you can also contact me.
