What Is Apple Watch Power Reserve Mode?

Power Reserve is an Apple Watch feature that lets you conserve battery life for as long as possible by disabling most of the Watch's features. You should only use it when your battery is low and you won't be able to recharge soon, but still want to know the time.

Power Reserve saves battery life by temporarily doing the following:

  • Stopping all communication between the Apple Watch and the iPhone it's paired with.
  • Disabling the Watch face you've chosen and any features normally available there.
  • Disabling access to all Apple Watch apps.
  • Only showing the time.

Since it removes most of the Watch's features, you should only use Power Reserve when you really need it — but in those times it comes in handy.

Is Power Reserve the Same Thing as Low Power Mode?

Basically, yes. When you need to conserve battery life on an iPhone by reducing its functionality, you turn on Low Power Mode. To do the same thing on the Apple Watch, you turn on Power Reserve. They're essentially the same, but just have different names.
