Watch ultra 2025 restarting with battery fully charged

[Justin2676]

My watch is a few weeks old and it just started to restart it self, yes the battery is fully charged

Thank you for reaching out, SecurityAgentJustin. I can certainly understand your concern with your watch restarting itself while the battery is fully charged. Just to clarify, when the watch restarts do you see any error messages prior to the restart? Does the watch keep restarting and not stay on like a boot loop symptom?

My issue there isn't an error, but battery drains and disconnects for barely 15 hours, even on power saving mode.

Hey there @Soepic,

I can see how frustrating it can be for your watch battery to drain and disconnect on you.

Have you attempted to clear the cache on your watch to see if that helps any?

Step 1. Swipe up from your Galaxy Watch Home screen.

Step 2. Tap on the Recent apps icon.

Step 3.  You may clear recently opened apps by swiping up on each app shown to close it or go all the way to the left and tap on the Close all icon to clear cache for all apps.

Also, have you tried rebooting the watch?

On your Galaxy Watch, press and hold both side buttons (Home/Power and Back) for about 10 seconds until the Samsung logo appears, then release to restart.

Have you double-checked your Bluetooth settings on both the Galaxy Watch and your phone?
