What to Do When a Smartwatch Update Fails or Gets Stuck

Start with a restart

The first thing to try when an update appears stuck is to restart both the smartwatch and the phone it is paired to. A restart clears temporary software states that can interfere with the update process. This is a low-risk step and often resolves a stalled download or installation.

On most smartwatches, you can restart by holding the side button or crown until the power menu appears, then choosing restart. If your watch has no visible restart option, check the maker's support pages for the correct button combination. After both devices restart, open the companion app on your phone and check whether the update is still available or resumes automatically.

Check the battery and charge level

Smartwatch operating systems usually require a minimum battery level before they will install an update. If the battery is low, the update may pause or fail. Put the watch on its charger and let it reach a comfortable battery level before trying again.

Keeping the watch on the charger during the update is a good practice. Many watches install updates faster and more reliably while charging, because the system can use more power without draining the battery. If the update is interrupted by a dead battery, the watch may be left in an incomplete state, so avoid starting an update when the battery is low.

Free up storage space

Updates need room to download and install. If your watch's storage is nearly full, the update may fail or get stuck partway. Check the storage section in the companion app or on the watch itself, and remove apps, music, or photos you no longer need.

The amount of storage required varies by the size of the update and the watch model. If you are unsure what to remove, start with the largest items: offline music, downloaded podcasts, and apps you have not opened in months. After freeing space, try the update again from the companion app.

Verify Bluetooth and Wi-Fi connections

Most smartwatch updates transfer from the phone to the watch over Bluetooth. The Bluetooth LE and Classic radios operate in the 2.4 GHz band, and the transfer can be slow for large updates. Make sure the watch and phone are close together and that Bluetooth is enabled on the phone.

Some watches can also download updates over Wi-Fi when connected to a network. If your watch supports Wi-Fi, connect it to a stable network and try the update from the watch's settings. A weak or unstable connection is a common reason for updates to stall; moving closer to the router or phone can help.

Retry the update after a pause

If the update appears stuck at a specific percentage for a long time, it may have paused rather than failed. Give it a little more time, especially for larger updates. If there is no progress after 30 minutes or so, cancel the update if the option is available, then start it again.

The companion app on your phone often shows the update status. If the app says the update failed, check the error message if one is shown, then try again. A second attempt frequently succeeds if the first failed due to a temporary network issue.

Unpair and re-pair the watch

When an update fails repeatedly, unpairing the watch from the phone and pairing it again can reset the connection and clear update-related glitches. The steps differ by platform: Apple Watch uses the Watch app on iPhone, while Wear OS watches use the Google Pixel Watch or Samsung Galaxy Watch apps, depending on the maker.

Before you unpair, check whether the maker's instructions say that unpairing will back up your data. Many watches create a backup automatically, but it is worth confirming. After re-pairing, check for the update again and try to install it once more.

Reset the watch as a last resort

If nothing else works, a factory reset may clear the problem. A reset erases all data on the watch and restores it to its original state, so only do this after you have confirmed that your data is backed up. After the reset, set up the watch again and update it before restoring your data.

A reset is the most disruptive step, but it can resolve issues that survive restarts and re-pairing. If the watch is stuck in a boot loop or will not respond at all, check the maker's support pages for the correct reset procedure, which may involve holding a specific button combination.

When to contact support

If the update still fails after restarting, charging, freeing storage, re-pairing, and resetting, contact the watch maker's support team. They can tell you whether there is a known issue with the update or a problem with your specific model. Keep your watch's model number and current software version handy when you call or chat.

Support may also offer a recovery procedure that is not available in the standard settings menu. Do not attempt hardware repairs on your own, as opening the watch can damage it and void the warranty. A support representative can guide you through safe recovery options or arrange a repair if needed.

What to pick for your use

Questions

Why does my smartwatch update keep failing?

The most common causes are low battery, insufficient storage, a weak Bluetooth or Wi-Fi connection, or a temporary software glitch. Restart both devices, charge the watch, free up storage, and try again.

Can I use my watch while it is updating?

It is best to leave the watch alone during an update. Using apps or starting a workout can interrupt the process. Keep the watch on its charger and let the update finish without interference.

Will I lose my data if an update fails?

A failed update usually does not erase your data, but a reset or a recovery procedure might. Check the maker's guidance on backups before you try any recovery steps, and make sure your data is backed up if possible.

How long should a smartwatch update take?

Update time varies with the size of the update and the connection type. Small updates may take minutes, while larger ones over Bluetooth can take longer. If there is no progress after 30 minutes, cancel and retry.

How do I know if an update is actually stuck?

If the progress bar or percentage has not moved for a long time, the update may be paused or stuck. Check the companion app on your phone for status details, and give it a little more time before canceling.

What should I do if my watch will not turn on after a failed update?

Put the watch on its charger and wait a few minutes. If it still will not turn on, try a forced restart using the button combination from the maker's support pages. If that does not work, contact support for recovery options.
