By connecting an external MagSafe battery to the iPhone 12 mini, we get a mobile complex that solves one of the main problems of the latter. Perhaps the main one. The mini’s battery, under the same load, discharges faster than other iPhones 12. The mini, a 5G-enabled smartphone, has a very low battery capacity. And a set of mini and an external MagSafe battery has a total capacity, theoretically, almost twice as much as a full-size iPhone 12. iPhone 12 is more expensive than iPhone 12 mini by about the cost of an external MagSafe battery. Is this a coincidence?
What I have called a complex of a smartphone and an external module several times is one to one that Android smartphone developers have been trying to create for a decade. Modular smartphone. At the center of the modular design is a smartphone with the most basic functions and means of connecting external modules for various purposes to it. But none of the attempts was crowned with success, the products “did not go”. Perhaps Apple does not think about turning the iPhone into a modular smartphone, but their complex of iPhone and an external MagSafe battery is exactly that. And the complex is exactly what modular smartphones should have been from the very beginning. If Apple took this direction seriously, it could succeed.
External MagSafe battery for iPhone
The next generation iPhone is two months away. In any case, Apple is doing everything it can to make it happen on time. The iPhone 12 mini has a terrible reputation. Because of the unkind publications in the press, because he really did not live up to Apple’s expectations, and because not all people know how to think and count. The small battery capacity also played a role, although it all depends on how the iPhone is used, many write that the charge is enough for them. The iPhone 12 mini will go down in history as Apple’s failure. But it’s not the last mini in Apple’s lineup. This is a chance for the iPhone 13 mini, with a larger battery and a phenomenally economical 5G modem from Qualcomm.
At the iPhone 12 presentation, the MagSafe external battery was not even mentioned. MagSafe Duo Charger has been promised to be released in the coming months. The external battery was much more important. The MagSafe Duo Charger also had significant issues, but there was no doubt that they would be fixed. The device only needed to be redone. This and the full testing cycle took time. And with the external battery MagSafe something similar happened to the story with AirPower. Overheating, software problems. The development team was given time until mid-February.
In February, Bloomberg’s Mark Gurman, citing a source at Apple, talked about the MagSafe battery project, which will either be delayed or canceled altogether. And what it would be like if the developers were given a little more time. What was told was displayed graphically, in the form of a concept – it is under the heading of the article. The information was reprinted in dozens of media outlets, in the comments to the publications, people wrote that they would buy this device, and someone was ready to pay any money for it. Then the team was given another chance. Three months of emergency work – and everything finally worked out. In a single combat between Apple and physics, Apple won this time. Although, whether she won or not, we will soon find out: sales of the device begin.
IPhone 12 Battery Capacity
Apple’s marketing documentation lists the iPhone battery capacity in milliampere-hours. In the case of the MagSafe external battery, this played a bad joke – Apple was accused of the disgustingly low capacity of this battery. That, at its rather high price, it was deadly. In fact, it’s not that bad. Misleading MagSafe battery specifications: 1,460 milliampere-hours or 11.13 Wh, operating voltage 7.62 volts. IPhone 12 batteries have more capacity, in milliampere-hours:
- iPhone 12 Pro Max: 3,687 milliampere-hours;
- iPhone 12 Pro: 2,815 milliampere-hours;
- iPhone 12: 2,815 milliampere-hours
- iPhone 12 mini: 2,227 milliampere-hours
The operating voltage for all iPhone 12s is 3.81 volts. If at 7.62 volts the capacity of the external MagSafe battery is 1,460 milliampere-hours, then at 3.81 volts it is 2,920 mAh. If it were not for the transfer of energy by wires, the charge of the external battery would be enough to fully charge the batteries of all iPhone 12s except the iPhone 12 Pro Max.
In chargers working according to the Qi (“Qi”) standard, the efficiency does not exceed 50%, but MagSafe is Apple’s own standard, an add-on over Qi. Since the transmitter and receiver coils in MagSafe are pressed together by magnets, one would expect MagSafe to be more effective. If Apple had reported it. But Apple is silent. Even taking into account the losses, the external battery looks quite adequate. If the user documentation indicated the capacity in Watt-hours, everything would be clear from the very beginning:
- MagSafe external battery: 11.13 Watt-hours;
- iPhone 12 Pro Max: 14.05 Watt-hours;
- iPhone 12 Pro: 10.73 Watt-hours
- iPhone 12: 10.73 Watt-hours
- iPhone 12 mini: 8.48 Watt-hours.
- The iPhone 12 mini with an external battery is theoretically 19.61 Watt-hours.
