What is Power Reserve Mode in iOS 14?

Power Reserve mode allows you to access certain functions of your iPhone even after the battery runs out. This can help you out in several situations when your phone might unexpectedly turn off, and you don’t have access to a charger.

Power Reserve will be available for up to 5 hours after your iPhone shuts down. It enables you to access some critical functions, as explained below.

Use of Power Reserve Mode on your iPhone

Power Reserve ties in with Apple’s vision of a future where your iPhone is the only essential thing you need to carry when out and about. That is, it can replace your physical wallet, cards, and now, even your car keys.

But it can be a problem when you don’t have these physical items with you, and your phone runs out of power. Here, power reserve comes to the rescue and enables you to use Express Transit and digital car keys for up to 5 hours after your iPhone battery dies. This ensures that you’re not left stranded just because your phone unexpectedly ran out of juice.

How Power Reserve Mode Works on iOS 14

Power Reserve works thanks to NFC tags and the “Express Card” feature on your iPhone. “Express Cards” don’t require Face ID or Touch ID authentication, so simply tagging an NFC tag allows the associated payment to go through. In the same way, tapping your iPhone to your car will unlock it if you’re using digital keys.
