With the release of iOS14.7, Apple’s latest MagSafe external battery is officially on sale. The official English name is MagSafe Battery Park, which is very similar to the previous Apple’s Smart Battery Case. It “smart shell”).
Since the iPhone 12 generation did not launch its own smart case, it is natural that users who have used the smart case will definitely compare the external battery with it.
Judging from the parameters of the MagSafe external battery, it is definitely not worth the price of 749 yuan:
Capacity less than 3000mAh
There is a 7.62V, 11.13Wh battery inside MagSafe with a capacity of 1460mAh (7.62V 1.46A);
Calculated according to the output 5V, the capacity is 2226mAh (5V 2.226A);
5W charging speed
As a mobile power supply, only 5W;
When connected to a charger above 20W, it can be used as a MagSafe wireless charging board to charge iPhone12 with 15W power;
But this has not been the essence of Apple’s smart charging products.
It is important to know that the MagSafe external battery does not need to be charged separately like a normal power bank. Regardless of whether the charging cable is plugged into the iPhone or the MagSafe external battery, the system will give priority to charging the iPhone’s battery first. When the iPhone’s battery is charged to 80% The system will only supply additional power to the MagSafe external battery. (Yes, that’s right, when you plug the charger into the phone, the iPhone 12 will enable the reverse charging function to charge the MagSafe external battery.) Users don’t have to worry about forgetting to charge the MagSafe external battery separately. It’s like connecting to the iPhone’s battery. Together, the remaining power can also be checked directly in the system, which is where it is “smart”.
In systems before iOS14.7, the MagSafe external battery can also charge the phone normally, but the reverse charging function of the iPhone 12 cannot be activated, and the icon of the MagSafe external battery cannot be correctly identified in the battery plug-in. This must be noted.
But in the era of Smart Battery Case, the battery of the protective case was directly connected to the iPhone through lightning, so when power was consumed, the system would prioritize the use of the battery in the protective case, and only use the iPhone itself when it is exhausted. This is also a point that all smart shell users talk about. But when it comes to the MagSafe external battery, everything is different.
Due to the inherent limitations of MagSafe charging mode, the external battery cannot be connected to the battery of the mobile phone. As a result, the battery power must be charged into the iPhone battery by the MagSafe external battery first, and then it is being consumed. This is completely different from smart case cooking that directly consumes the battery in the phone case. There will be more or less loss of magnetic charge and discharge in the middle.
In addition, due to the limitation of 5W charging power in battery mode, the battery of the iPhone body often keeps powering down while watching movies, playing games, and other power-consuming usage scenarios, but the battery of the MagSafe external battery does not fail. Case. During the test, I tried iPhone12 and used Geekbench5 to run several times. The battery power of the phone dropped from 69% to 55% by 14%, and the power of the MagSafe external battery only dropped by 4%? ? ? ? ?
After that, I put the screen of the phone aside and concentrated on using the computer code. When I picked it up, I could pour it well. The battery of the phone was charged from 55 to 58%, which was 3% more, while the power of the MagSafe external battery dropped directly from 85% to 76. %, I used 9% of the battery to charge the phone 3%, Apple really has yours…
Isn’t this just the opposite of the ideal use method when it was launched… Since MagSafe’s charging protocol supports a maximum of 15W, why the official external battery pack only gives 5W?
The reason is likely to be fever.
This generation of iPhone 12 uses a 5nm A14 processor with very powerful performance, but everyone understands that this generation of products has overturned in terms of heat dissipation.
If the iPhone 12 is not equipped with a radiator during the game, the picture will often get stuck like a slideshow, and sometimes even if it is placed in the car for navigation and held in the hand for a long time video call, the phone will become hot. To the problem that can’t be held. Then, if you use 15W of power to charge the MagSafe external battery directly throughout the day, the phone will most likely be useless (refer to the heating performance of the phone after the MagSafe charger is directly charged with a 20W charging head).
So Apple can only take the second place. The 5W small water pipe will nourish you. Regardless of the charging speed, first solve the heat problem. This time, the heating control of the MagSafe external battery was really good, and the battery temperature did not exceed 30 degrees during the whole process. But the problem is that there is not much difference between 5W charging and no charging…
To sum up, the MagSafe external battery wants to inherit the position of the “smart case” of the big brother, and it is still far away. I hope that the iPhone 13 can let the Smart Battery Case return to its place earlier. As for the MagSafe external battery…Whoever prefers to use it.
