How does Apple Watch storage capacity work?

The way Apple Watch’s storage capacity works should be straightforward.

When you check your Apple Watch’s storage in the Watch app or your watch’s Settings app, you see two sections: Capacity and Available.

  • To check in the Watch app, go to My Watch > General > About or General > Storage ( or Usage.)
  • To check on the Watch, go to Settings > General > About or General > Storage (or Usage.)

capacity and available storage on Apple Watch

  • Capacity is the amount of storage that the device can hold.
    • On watchOS 7 and below, the listed capacity is your watch’s total storage minus its system partition (more about this later.)
    • On watchOS 8 and above, the listed capacity is your watch’s total storage, including its system partition.
  • Available shows you how much space your device has to use. 

Some users are upset that their watch’s listed Capacity amount doesn’t equal the advertised storage space.

For example, Apple lists my Apple Watch Series 6 (running watchOS 7.6) as having 32 GB of storage. But when I check in the Watch app or the Settings app on my watch, it shows its total capacity as 26.3 GB. That’s a difference of 5.7 GB! Kind of a lot.

But, Apple has an explanation for this discrepancy.

While your Apple Watch advertises a certain amount of storage, you do not have access to all of it. All of Apple’s devices follow this method.

So why’s that? Easy. Your Apple Watch keeps some storage for itself so that it can hold the operating system. This is known as the watch’s system partition.

  • If your watch uses watchOS 7 and below, your watch does not include the space used by its system (watchOS) in calculating its total capacity.
  • However, starting in watchOS 8, Apple changes this, and now capacity reflects all storage, including the system partition.

So the main reason why your device’s storage capacity numbers don’t add up if your watch runs watchOS 7 or below is that it does not display your watch’s storage partition (watchOS.) That makes sense, right?

And so do all those pre-installed Apple Watch apps. With all of those installed on your Apple Watch by default, that leaves less storage space available for whatever you want to add!

The good news is you can remove many of those pre-installed apps to free up storage on your apple watch!

Delete pre-installed apps from your Apple Watch 

  1. In grid view, tap and hold an app from your watch’s home screen until the app icons jiggle. Tap the “x” delete button in the corner of the app that you want to delete, then confirm Delete App. remove apple watch apps from your watch
    1. If you see the view options screen, tap Edit Apps, then press the “x” delete button.
  2. For watches that use a home screen in list view, swipe left on the app you want to delete, then tap the red delete button and confirm. apple watch delete apps in list view

You can also remove the built-in apps by deleting them from your iPhone. When you delete an app on your iPhone, Apple also removes that app from your Apple Watch.

Is your Apple Watch’s storage capacity or available storage unusually low?

If your Apple Watch’s storage capacity seems low and abnormal, there might be something wrong with your device.

Luckily there’s a fix for that! All you have to do is unpair your Apple Watch.
