MagSafe Battery Pack is the new introduction to the Apple accessories list.
It is designed to charge the iPhone 12 and 12 Pro (the only series with MagSafe currently) quickly and safely through wireless technology. Hopefully, in the future, Apple makes iPhone13 and above with MagSafe or might remove it. But currently, this is the sensation and style. The MagSafe Battery Pack can charge even faster when coupled with a 27W or higher charger (same as MacBook). And when you’re in need of a wireless charger, just plug in a Lightning cable for up to 15W of wireless charging.
Before using the MagSafe Battery Pack first time, remember to charge it using a Lightning to USB cable with a 20W or higher power adapter.
Plug the lightning cable end of your Lightning to USB cable into the Lightning connector on your MagSafe Battery Pack.
Plug the USB end of the cable into a 20W or higher USB power adapter and provide the power.
You'll see an amber status light while your MagSafe Battery Pack is charging. When the MagSafe Battery Pack is fully charged, you'll briefly see a green status light.
Using an adapter that isn't 20W or higher will result in a slower charge.
However, when charging on the go, the MagSafe Battery Pack can charge your iPhone with up to 5W of power. Whereas if connected to a 20W or higher power source, it can charge with up to 15W of power.
Charge your MagSafe Battery Pack and your iPhone at the same time if you want, please remember the following.
Attach your MagSafe Battery Pack to your iPhone and then plug the MagSafe Battery Pack into a power adapter. Using a 20W or higher power adapter, the MagSafe Battery Pack can charge your iPhone with up to 15W of charging power.
You can also charge both if you attach your MagSafe Battery Pack to your iPhone, and then plug your iPhone into a power source. You might want to charge this way if you need to connect your iPhone to another device while charging, like if you're using wired CarPlay or transferring photos to a Mac.
But remember, if you charge your iPhone and MagSafe Battery Pack at the same time, your iPhone might charge to 80% or higher before your MagSafe Battery Pack begins charging.
If you are using any other case that holds items such as credit cards, remove them before charging with your MagSafe Battery Pack.
Your iPhone may get slightly warmer while it charges. To extend the lifespan of your battery, if the battery gets too warm, the software might limit charging above 80%. Your iPhone will charge again when the temperature drops.
The MagSafe Battery Pack includes a charge management feature to help maintain battery health in cases where your MagSafe Battery Pack is connected to power for prolonged periods of time.
If you keep your iPhone in a leather case while charging with your MagSafe Battery Pack, the case might show imprints from the compression of the leather. This is normal, but if you’re concerned about this, Apple suggests using a non-leather case.
Make sure that your MagSafe-compatible iPhone is running iOS 14.7 or later. When you attach your MagSafe Battery Pack to your iPhone, it will start charging your iPhone automatically, and a charging status will appear on the Lock screen.
Apple MagSafe Battery Pack specifications
1,460mAh
7.62V
11.13Wh
iPhone battery capacities
iPhone 12 Pro Max - 3,687mAh
iPhone 12 Pro - 2,815mAh
iPhone 12 - 2,815mAh
iPhone 12 mini - 2,227mAh
In terms of Watt-hours, mathematically, we can compare these ratings in many ways, but the amount of charge the battery provides will remain the same. While most battery packs use the milliamp-hour rating to represent capacity, Watt-hours would better explain the overall capacity without errors due to voltage differences.
The watt-hour value is a better indicator of overall device capacity because it takes voltage and amperage into account.
MagSafe Battery Pack - 11.13Wh
iPhone 12 Pro Max - 14.05Wh
iPhone 12 Pro - 10.73Wh
iPhone 12 - 10.73Wh
iPhone 12 mini - 8.48Wh
Using this metric, we can see the MagSafe Battery Pack lies squarely between the iPhone 12 and iPhone 12 Pro Max in terms of total capacity. When we account for charging efficiency then the numbers aren't quite so impressive but adequate given the battery pack's size. At 70% efficiency, the MagSafe Battery Pack would charge the iPhone 12 mini to about 90% capacity from zero.
Charging efficiency
There are a number of factors users should take into account when considering the battery capacity. While the numbers look good on paper for the MagSafe Battery Pack, once the ratings are properly examined, efficiency isn't 100%.
Apple acknowledges this by programming some intelligence into the iPhone and MagSafe Battery Pack. To get the most out of using the MagSafe Battery Pack, Apple doesn't allow it to charge the iPhone at the same speed, given the conditions of the charge, including heat, and the charged iPhone's battery characteristics.
Apple's Intelligent charging features
MagSafe Battery Pack will stop providing a charge if the iPhone reaches 90%
If the iPhone becomes too hot, the MagSafe Battery Pack stops charging over 80%
The MagSafe Battery Pack will ensure the iPhone reaches a full charge first before using connected power to charge itself
The iPhone can charge the MagSafe Battery Pack through reverse charging if its internal battery is full and connected to power
Apple takes into account temperature considerations during any charging process. Introducing too much heat to a lithium-ion battery will cause it to degrade faster, so it isn't recommended to use wireless charging in overly hot environments.
Luckily, users do not need to consider charging efficiency or temperature when using their devices. Baked-in intelligence will handle all of this for them, so inefficient charging isn't taking place
