Apple Has Updated Its MagSafe Battery’s Firmware to Add Slightly Faster Charging

Written by Nuel

My favorite kind of software update is the kind that unlocks secret hardware features, and the Apple MagSafe Battery Pack is the latest surprise: once you apply firmware update 2.7, you’ll be able to cordlessly charge an iPhone at a faster 7.5W instead of the original 5W, via a report from 9to5Mac.


You can wait for an update over the air or plug a Lightning-to-USB cable from the pack to a connected Mac or iPad to get the fix, and then you’re off to the races, as they say.

But if I’m being honest, I wouldn’t install the update quite yet. I might wait until we hear back from Apple (or reviewers) about whether it’ll affect how warm the battery gets.


Highlights like having the option to check its charge level right in iOS and charging that naturally begins when the battery’s appended to an iPhone made the Apple MagSafe Battery Pack our top decision last year, yet we deplored its more slow charging speeds when turned off: a restriction that Apple has improved with a new firmware update.


Contending MagSafe batteries like the Mophie Snap+ Juice Pack Mini and the Zens Magnetic Dual Powerbank both figure out how to marshal 7.5W charging speeds. When connected to a power source (more noteworthy than 20W), the Apple MagSafe Battery Pack can charge an iPhone at 15W through its attractive association, however, that invalidates the transportability managed the cost of while cutting the line, which then, at that point, cuts the Apple battery’s running after speed to simply 5W.

Be that as it may, as per a new update to the “How to utilize your MagSafe Battery Pack” support page on the Apple site, a new firmware update to rendition 2.7 now helps the Apple MagSafe Battery Pack’s compact accelerate to 7.5W, putting it comparable to the opposition.


Heat is an unwanted byproduct of wireless charging that not only wastes power but can also reduce a battery’s longevity and capacity, which is one of the reasons Apple originally limited charging speeds to 5W. Apple doesn’t go into details about what has changed in the v2.7 firmware update to remove this limit, but it’s either stopped worrying about the heat generated by faster charging, or it’s introduced some new ways to mitigate it through the update.

With the Apple MagSafe Battery Pack attached to your MagSafe-compatible iPhone, you can check its firmware version by opening iOS’ Settings and going to General > About > MagSafe Battery Pack, which should appear beneath “Carrier Lock” information. According to Apple, its MagSafe Battery Pack should automatically update itself when attached to an iPhone with an internet connection, but it could take about a week for that to happen as the update rolls out. For the less patient, Apple’s support page claims that users can also “plug one end of a Lightning to USB cable into the Lightning connector on your battery pack, and the other end into your Mac or iPad” which should download and install the firmware update in about five minutes, but so far we haven’t had any success taking that route.
You see, I bought a MagSafe Battery Pack myself last year for my iPhone mini, but I returned the pack pretty quick. As I’ve written, the Mini-MagSafe combo felt uncomfortably warm without a case — but with a case, the MagSafe Battery Pack felt a bit too loose and tended to slide around while I held it. (Yes, I was using Apple’s own Clear Case with MagSafe, not some third-party knockoff.)
And so, I’m having a hard time imagining that getting better now that the MagSafe Battery Pack puts out more juice. In our review of the MagSafe Battery Pack, Dieter Bohn pointed out that the 5W charging speed was meant to minimize heat and preserve the battery’s longevity.
Presently, maybe Apple has made different changes also that will nullify the hotness issue — the organization could have changed the recurrence and length of the charge. Maybe assuming it charges at 7.5W for brief periods, it’ll have to charge now and again, and it could even be less irritating for those of us hefting it around day in and day out.

Provided that this is true, I could get one once more. I’ve contacted Apple, and I’ll tell you what the organization says.
