If a Galaxy Watch update fails, battery life worsens, or the watch stops staying connected, start with the least disruptive checks: confirm the phone has internet and Bluetooth is on, let an update finish if it is still progressing, and restart a watch that is truly frozen. Samsung’s update steps require a Bluetooth connection to a phone, but menu labels and available features vary by model, software version, country, and carrier.

Galaxy Watch update failed or appears stuck

A temporary disconnection from the phone during installation does not necessarily mean the update failed. Samsung says an update can take several minutes and the watch may disconnect while installing; the display may show a progress percentage or an exclamation mark. Avoid interrupting an update that is still progressing. Samsung does not specify a universal timeout for deciding that every model is stalled.

Check the connection and run the update

  1. Confirm the phone has a network connection and Bluetooth is enabled, with the watch paired to the phone.
  2. Open Galaxy Wearable and go to Watch settings (or the settings tab on some app versions) > About watch > Update watch software.
  3. Choose Update now or Download updates manually, depending on the menu shown, and follow the prompts. Keep the watch and phone nearby while the update runs.

Samsung states that a network connection is required and that the watch must be connected to a phone over Bluetooth to update. The exact labels can differ across watch generations and software versions. Samsung’s Galaxy Watch update instructions describe the update process and temporary disconnect during installation.

Restart a genuinely frozen watch

If the watch is unresponsive rather than displaying update progress, force-reboot it by pressing and holding the Home/Power and Back keys together until Rebooting… appears, then release them. The hold time varies by model; some watches may take up to 30 seconds. After restart, check for updates to the watch software, Galaxy Wearable, and the watch’s device plugins. Also update the apps on the watch. See Samsung’s restart and reset guidance.

Galaxy Watch battery draining fast after an update

Faster battery drain after an update does not by itself establish that the update caused it. Samsung’s general troubleshooting guidance recommends checking software and app updates, since an app bug can consume excess power, and changing settings that increase power use.

Reduce power use without losing track of trade-offs

  • Close apps you are not using and install available app and watch software updates.
  • Lower screen brightness and turn off Always On Display if you do not need it.
  • Disable GPS when you are not using a feature that needs location.
  • Reduce notifications you do not need.
  • Review Wi-Fi, Bluetooth, and mobile-network use. Turning off a radio may save power, but can disable features or disconnect the watch from the phone.

Samsung notes that a newly set-up watch may use more battery while apps install and setup completes. It also says usage-pattern learning can affect performance for about the first week of ownership. That guidance concerns a new watch; it is not a promise that battery drain after a software update will resolve on its own. Samsung’s battery-life guidance covers these settings and setup considerations.

Check battery health if the drain remains severe

If the watch is paired with a Samsung phone, Samsung points to diagnostics in Samsung Members for checking the watch battery. Samsung says a passed test indicates the battery is in good condition. If the diagnostic fails or severe drain continues, contact Samsung support or service rather than assuming settings changes will fix a failing battery.

TechRadar has summarized user complaints about substantial drain after software updates on multiple models and mentioned Google Play Services as a possible culprit. This is a report of complaints, not a Samsung-confirmed cause or a diagnosis that applies to every affected watch. Read TechRadar’s report.

Galaxy Watch will not connect or keeps disconnecting

Check that Bluetooth is enabled on both the phone and watch, and that the watch appears connected in Galaxy Wearable. Bluetooth is required for the phone-connected update process. Turning off Bluetooth disconnects the watch from the phone; Wi-Fi remote connection also will not work if Bluetooth and Wi-Fi are both off.

If restarting the devices does not resolve a persistent connection or app problem, a reset is a later option—not the first step. A reset restores the watch to default settings and can remove data, so back up before proceeding.

  2. In the phone’s Bluetooth settings, unpair the watch.
  3. Reset the watch using the reset option in its settings, then reconnect it through Galaxy Wearable.
  4. After reconnection, check for watch software updates.

Menu names and backup options can vary by model and software version. For an LTE watch activated using a carrier QR code, Samsung says a new QR code may be required from the carrier after reset and reconnection. Follow Samsung’s reset instructions for your model.

When to stop troubleshooting

Contact Samsung service if physical damage—such as a stuck button—prevents restarting the watch, or if the problem persists after the applicable software steps. Samsung recommends approved chargers and accessories. If you suspect a charging problem, confirm the charger is compatible with your precise watch model and region before replacing it. Samsung’s regional support guidance lists EP-OR900 for Watch5 and Watch6 and EP-OL300 for several newer models, including Watch7 and Watch8; regional product families may differ, so verify compatibility with Samsung before buying. Samsung’s regional charger list provides model details.

Software availability also varies by model and market. For example, Samsung’s Galaxy Watch6 SM-R935F release history lists build R935FXXS2CZF5, released 2026-07-13, with a 2026-07-05 security patch level. That is a model- and market-specific record, not a universal latest version. Samsung notes that changes may differ by device, country, and service provider. Samsung’s Galaxy Watch6 SM-R935F update history shows that release record.
