- What is MagSafe?
MagSafe is a magnetic wireless power transfer standard originally introduced in 2006 on the Mac line of laptops and computers.On October 13, 2020, Apple released a new version of MagSafe, along with the iPhone 12 and iPhone 12 Pro.The new version of MagSafe delivers up to 15w of power and is backwards compatible with the Qi standard. So MagSafe is divided into two parts to look at MagSafe for Mac and MagSafe for iPhone.
MagSafe for Mac
MagSafe first appeared on January 10, 2006 at the MacWorld conference and expo, through the magnetic fixed power connector, in the person accidentally tripped over the wire can be safely removed from the power connector, and will not be dragged down to the computer will not be torn off the fall caused by the damage, which can greatly enhance the safety of the person as well as the computer.
MagSafe for iPhone
In 2017, Apple launched the iPhone 8 and iPhone X wireless charging (Qi), and the subsequent launch of the iPhone are added to the wireless charging function, but the charging wattage speed limit of the fastest only 7.5W, coupled with the phone and the charger can not be fixed position, resulting in the possibility of misalignment and can not charge the electricity into the phone, in order to solve the problem, Apple will be the magnetic suction technology applied to the wireless charger in 2020 with the release of the iPhone 12, launched a new generation of specially designed for the iPhone MagSafe charger, and all phones after the iPhone 12 have also been introduced to MagSafe for iPhone. In order to solve the problem, Apple applied the magnetic charger technology to the wireless charger, and in 2020, with the release of the iPhone 12, launched a new generation of MagSafe chargers designed specifically for the iPhone, and all cell phones after the iPhone 12 have also introduced the MagSafe magnetic charging function.
Apple utilizes the technology of electromagnetic induction, in which a magnetosphere produces a magnetic field change when energized, driving the flow of electrons to produce a rechargeable current. On the basis of electromagnetic induction, the wireless charging coil inside the cell phone (Charging coil) to add a ring of magnets (Magnet array), so that support MagSafe charger can be accurately adsorbed in the correct charging position, to achieve close adsorption will not be easily displaced charging, but also the original maximum of 7.5W charging speed up to 15W, and Nanocrystalline panels and two sensors have been added to increase the sensitivity of the magnetic field, and the E-shield design has been improved to increase the safety of charging.
2. Understanding Made For MagSafe (MFM) and MagSafe Compatible
MagSafe is a patented technology introduced by Apple. Through magnetic adsorption, it can effectively get rid of the problem of mobile devices being entangled by wires when in use, and is now widely used in peripheral devices such as protective cases, chargers, mobile power supplies, and card holders, etc. The MFM certification is similar to the previous Made For iPhone (MFi) certification, and peripheral device manufacturers must pass Apple’s rigorous review mechanism to obtain Apple’s certification. Peripheral device manufacturers must pass Apple’s rigorous review mechanism in order to obtain Apple’s certification authorization and receive the MFM certification seal.
MagSafe Compatible (MagSafe Compatible) is a charger with the function of magnetic attraction, but because it does not pass the MFM certification, so in the charging of the iPhone, as mentioned in the previous table, it can only go for the Qi wireless charging specification, that is, the maximum wireless charging speed of 7.5W. But for charging other Android devices, assuming the MagSafe-compatible charging pads offer 15W charging speeds, this charger can provide up to 15W wireless charging speeds for Android phones, assuming of course that your Android device supports the Qi 15W charging rate as well.
I still prefer to use MagSafe before, the biggest advantage is that charging is convenient, put it on, and that is when the iPhone charging port is broken, magsafe this time is also particularly useful, after all, the price of replacing one is still relatively expensive, but MagSafe still has a big disadvantage, so that my iPhone heat like a small stove, and charging speed is super slow.
There was this question before, does magsafe charging hurt the battery? , and I’m sure a lot of people with iPhones would love to know the answer. Theoretically, battery loss occurs during charging and discharging as well as during use, and compared to wired charging, magsafe uses magnetic charging to generate heat to a higher degree than wired, and the battery depletes faster at higher temperatures, so magsafe is more likely to exacerbate the loss of the battery.
Battery health declines rapidly
Some users have reported that after only two weeks of charging with MagSafe, the iPhone’s battery health dropped from a full 100% to 97%. In comparison, many iPhone users don’t even get to 99% in half a year. This is simply a “speed ladder” of battery health.
Wired charging is the way to go.
So, is there a better way to charge? Of course there is!
- with the official 20W charging head
- with original data cable
- control the charging range from 20% to 80%.
This will not only charge faster, but also reduce the heat generation after 80%, which will help prolong the battery life.
An enthusiastic netizen shared his charging tips: use the official charger during the daytime to charge as you go, and switch to the original 5V 1A slow charger at night. His 13 Pro Max still has 90% battery health after two years of use. It seems that slow charging does minimize heat generation and protects the battery.
Other uses for MagSafe
More than just a charger
While I no longer recommend the MagSafe as a charger, it’s still useful as a stand-mounted accessory for your iPhone. Especially for those who drive a lot, the MagSafe is definitely a great indispensable addition to your car.
The Best Advice ——
If you are also concerned about battery health, then consider this:
- opt for a MagSafe accessory that only serves to hold it in place.
- Use it in combination with wired charging.
This way you can enjoy the convenience of MagSafe and protect your battery health at the same time.
