Older isn’t always better (when it comes to Apple Watch)

With the latest watchOS update, the older model Apple Watches really seem to bear the brunt of this problem. In particular, our Apple Watch Series 3 (WiFi model) does not have enough storage to install the update. apple watch series 1 to 5

The main reason older Apple Watch series have issues updating is the total storage available on these devices is limited.

This is especially true for the Series 3 WiFi-only model (called the GPS model), which Apple limited to 8 GB just like its predecessors–while the Series 3 Cellular LTE model includes 16GB, just like the Series 4. Apple Watch Series 3 Wifi model limited on board storage

Total storage on Apple Watch by series

  • Original, Series 1, Series 2, and Series 3 (WiFi model): 8 GB
  • Series 3 (Cellular LTE e-SIM): 16 GB
  • Apple Watch Series 4: 16 GB
  • Series 5: 32 GB

And of course, even when your Apple Watch has 8GB–that does not correspond to available storage. In order to update your watch, you need to have a significant amount of available storage. So let’s check your watch’s available storage.

For Update problems associated with Apple Watch Series 3 and watchOS 7, A great synopsis of required steps were shared by a reddit user u/UCGos25.

Apple Watch unable to Update to watchOS 7, Fix it now

Why? For some reason watchOS gets bloated and takes up a bunch of space you can’t get rid of without resetting it.

Here’s the best way to do it:

TRY THIS FIRST

PSA from u/TripleDallas123 – Try simply turning it off and back on. It was 2.8GB remaining for me and after I simply restarted I had 3.3GB which met the 3.1GB quota. If that doesn’t work, the factory reset will probably be the only way…

IF THAT DOESN’T WORK, TRY METHOD BELOW

  1. Make sure your watch is backed up to iCloud. This way you can recover apps, settings, and data after updating. To do this, go into iPhone Settings -> [YOUR NAME] at the top -> iCloud -> iCloud Backup -> Back Up Now.

  2. Go into the Watch App > General > Reset > Erase Apple Watch Content and Settings.

  3. Pair your watch to your iPhone.

  4. Backup from iCloud. Pick your backup.

  5. After the watch sets up, check for a new update. You should have enough space.

BONUS: The download is slow because the phone downloads it and transfers to the watch via Bluetooth. To download faster, turn off Bluetooth and download directly on the watch. Make sure the watch is charging for the entire thing though.

For a detailed look at some of the steps that you can take to free up storage on your Apple Watch, please see below:

Remove third-party apps from your Apple Watch

Apps don’t usually account for much of your storage, but if you’ve deleted all the app media and still don’t have sufficient space for the watchOS update, then you need to start deleting apps.

Start by deleting third-party apps from your watch

  1. On your paired iPhone, open the Watch app and choose the My Watch tab
  2. Scroll down until you reach the section Installed on Apple Watch
  3. Tap a listed app

Remove Apple’s built-in native apps from Apple Watch

If you use watchOS 6 or above, you can delete some of Apple’s native apps directly from your Apple Watch.

As of this writing, you can delete these Apple’s first-party apps from your Apple Watch: Alarm, Timer, Stopwatch, Remote, Camera Remote, Radio, ECG, Breathe, Noise, and Cycle Tracking.

While you can delete these apps, we don’t recommend doing it unless you’ve exhausted all other storage-savings options. That’s because once you remove these apps, you need to reinstall them via your Apple’s Watch’s app store–and that is often not as easy as it sounds!

How to delete Apple apps from your Apple Watch

  1. On your Apple Watch, go to the Home Screen
  2. Press and hold one of the listed app’s icon until you see an x on the icon remove an app from the Apple Watch without the iPhone

    1. The app is not deleted from your paired iPhone
  4. If you use a List View for apps instead of a home screen
    1. Swipe left on an app’s name and then tap the trashcan to remove it. Confirm you want to delete that app Remove apps from apple watch with a list view app home screen

No seeing the “x” to remove an app or no trashcan icon?

If you do not see “x” or the trashcan, that’s a built-in app that Apple does not allow users to remove from their Apple Watches.

How to reinstall deleted built-in Apple apps for your Apple Watch

  1. Open the App Store app on your Apple Watch Apple Watch app store and search for app feature
  2. Tap Search
  3. Choose Dictation or the Scribble Pad find an app using the Apple Watch App Store app
  4. Speak or scrawl the name of the app you want adding “Apple” or “Apples” to the beginning
    1. For example, say or scribble “Apple’s Timer” or “Apple Alarms”
  5. Once you see the name typed out on your watch’s screen, press Done
  6. Scroll through the list of displayed apps and tap the download cloud to reinstall the app Install an app from apple watch app store
    1. If you don’t see the download cloud, it’s likely not Apple’s official version so continue to scroll for the official version
  7. Repeat for any other apps you removed and want to restore to your watch

Still can’t update your Apple Watch after deleting media and apps? Unpair it, then update

Unfortunately, this is a long and tedious process, especially if you want to preserve all your current watch settings (requires restoring to a backup.) Be prepared to spend several hours on this task!

FAQsFAQ frequently asked questions

How many apps do I need to delete to free up space?

Unfortunately, there is no “golden rule” here. It all depends on how much available space the watch update requires (as listed in the error message) and how much space you need to open up for that update.

As the article mentions, we recommend deleting media content first, since these are usually the bulk of your Watch’s storage. That includes things like photos, downloaded music, podcasts, and audiobooks.

Does my iPhone or Apple Watch recommend any apps for me to delete that I haven’t used recently?

While your Apple Watch does not provide a list of apps that you recently used or haven’t used in a while, your iPhone does!

To see this list, on your paired iPhone go to Settings > General > iPhone Storage. Wait for the information to populate and then scroll down the list of Apps to see information about your use of apps.

offload unused apps on iPhone

You may also see a recommendation to Offload Unused Apps–enabling this removes the app from your iPhone and if available, from your Apple Watch but keeps your data so you can reinstall it later and preserve all your information.
