Faster charging for the MagSafe Battery Pack is now possible thanks to an upgraded firmware. Previously, the MagSafe pack could charge an iPhone to a maximum of 15 watts when connected to a 20 watt charger; however, the MagSafe Battery Pack can now charge an iPhone to a maximum of 7.5 watts while disconnected from a power source. It was previously limited to charging at a maximum of 5W when on the go.
According to a report from 9to5Mac, the Apple MagSafe Battery Pack will be able to charge an iPhone at 7.5W instead of the original 5W with the current firmware version 2.7, which is my favourite sort of software update since it reveals previously hidden hardware functionality.
To acquire the patch, you may either wait for an update over the air or connect a Lightning-to-USB connection from the pack to a linked Mac or iPad.
As for the update, if it were up to me, I wouldn’t bother. Apple (or reviewers) may have to answer this question before I make my final decision.
You know, I purchased a MagSafe Battery Pack for my iPhone mini last year, but I returned it quickly. When using the Mini-MagSafe combination, I found it to be excessively warm, but with a case, the MagSafe Battery Pack seemed a little loose and moved about when I handled it. The Clear Case with MagSafe that I was using was Apple’s genuine product, not a third-party imitation.
MagSafe Battery Packs may now be upgraded via Apple’s support website. The Pack may be updated on an iPhone, iPad, or Mac. In this case, the Pack will auto-update while connected to the iPhone, although it may take up to a week. According to Apple, updating an iPad or Mac using the MagSafe Battery Pack should take no more than five minutes.
Connect the MagSafe Battery Pack to your iPhone and check Settings > General > About > MagSafe Battery Pack to see whether the most recent update (version 2.7) has been installed.
