With the introduction of the iPhone 12 and iPhone 12 Pro, Apple has reinvented MagSafe magnetic charging cables. The name broke in the market for magnetic cables designed exclusively for the MacBook. Repurposed, MagSafe still persists for the magnet-based accessories but this time for iPhone. Each iPhone 12 model comes with a built-in ring of magnets that help MagSafe accessories to adhere to the phone. In this article, we are going to learn about the MagSafe charging warnings for iPhone users. But before that let’s orient our attention towards the working mechanism of MagSafe chargers to better understand the issues and be able to find the relevant solutions.

How MagSafe Works?

All the magnet-based MagSafe accessories, be it chargers or cases, everything works on a basic mechanism of magnetism. The MagSafe accessories have a built-in magnet so as to connect to the counter magnet on the iPhone 12 models. For example, Apple’s MagSafe charger snaps right on the back of the iPhone, just how a magnet snaps onto a refrigerator.

The magnetic ring design allows iPhone 12 models to be compatible with a full range of magnet-based accessories, from chargers to mounts and cases. iPhone 12 models have a ring of 18 rectangular magnets arranged in a circular pattern located below the wireless charging coil, allowing MagSafe accessories to work with iPhone devices.
The MagSafe charger looks like a larger Apple Watch charging disc with an aluminum body and a soft white material on top of the charger. The charger fits an iPhone 12 with magnets inside, perfectly aligning the charging coil of the MagSafe charger with the charging coil of the iPhone.

Apple has also designed the MagSafe Duo charger, which combines a MagSafe charger with an Apple Watch charging pad. The charger is foldable, making it great for travel, and it costs $ 129. The MagSafe charger can charge a maximum of 15W for most of the iPhone 12 models. But the charging maxes out at 12W for iPhone 12 mini. The same goes for the MagSafe Duo. Also, remember that the temperature of the iPhone can also have an impact on the charging speeds.

To achieve 15W charging speeds for iPhone 12 (or 12W for iPhone 12 mini) you require an Apple 20 W power adapter or another 20W+ PD 3.0 charger. But testing with an 18 W iPad and 96W Macbook Pro charger did not support MagSafe to reach full 15 W. According to Apple, to reach the charging maximum of 15 W, a MagSafe charger needs to support Power Delivery 3.0 at 9V/2.22A. For the iPhone 12 mini to hit the maximum charging speed of 12W, a power with a 9V/2.03A is required.

Limitations of MagSafe Charger

Though MagSafe chargers are a great blessing for iPhone users the magnet-based charging technology poses a few limitations. Let’s find out what are the challenges faced by the users.

⦁ One of the potential hitches involves heat buildup that can limit charging. If the Apple device gets too warm, charging will be limited to 80 percent only. While this might affect you much if you’re the one who prefers charging the phone overnight this poses a challenge for those who top up quickly before running to work

⦁ Another issue that may come your way is demagnetization. If you are someone who carries a credit card, with RFID chips or magnetic strips, security badges, passports, and key fobs; a Magnetic Charger is something that may not fit you. If any of these somehow get in between the iPhone and the MagSafe charger, could get demagnetized or ruined completely. You may not be able to unlock the door or pay at the store the next time you move out of your house. Though Apple offers a MagSafe wallet the odds of getting a credit card in between the charger and the iPhone are slim.

⦁ Another issue arises for people who prefer leather cases. The MagSafe charger can leave circular imprints ruining your favorite leather case that you got recently from the store. Similar damage has also been reported in silicon cases as well. Now, this sort of damage arises a valid question of what will happen to the glass back of the iPhone of the users who go without case over time as the charger is used. The potential damage to iPhone 12 or 12 Pro’s glass back can cost you a good sum between $449 and $549 depending on the model you’re using.

⦁ Apple has also raised warnings for its users as cases of magnetic interference have been observed. Though iPhone 12 contains more magnets than any prior iPhone model till now which reduces the risk of magnetic interference it is suggested to stop using the MagSafe accessories or iPhone devices if you come across such experience. This is because incidents reported have proved the possibility of MagSafe accessories and iPhone devices to cause electromagnetic interference with medical devices such as pacemakers and defibrillators.

⦁ You may also encounter a mismatch of the electric device connection if your iPhone is connected to power via Lightning port while on charging. Your iPhone won’t charge wirelessly if simultaneously connected to power- instead, your iPhone will charge via the lightning connector.

Takeaways

The MagSafe magnet-based charging technology chops off the wire hazard as it unclasps the cable instantly. The MagSafe chargers work by non-axial force which means the charger disconnects automatically if pulled in any director other than straight. There are tons of benefits and drawbacks to MagSafe’s magnet-based charging technology. While none of the demerits are hazardous but can certainly be annoying for a mobile device that costs so much. This is a high-cost, high-maintenance technology whose potential risks can outweigh the benefits of simplified wireless charging.
