Start with the settings that shape everyday use: choose whether you want Always On Display or longer battery life, trim notifications to the alerts you want on your wrist, then configure the Quick Button for an activity you use. Review health and emergency features after checking their limits and availability. Menu names and paths can vary by software version and region; Samsung’s English Galaxy Watch Ultra manual is for OS 6.0, version 1.1, dated August 5, 2025.
1. Choose between glanceability and battery life
Always On Display is the simplest first decision: it keeps the watch face visible at a glance, while turning it off can help extend runtime. Samsung estimates up to 60 hours with Always On Display on and up to 80 hours with it off in normal battery mode, with Power saving and Exercise power saving off. These are Samsung figures under stated conditions, not a promise for an individual watch; actual battery life varies with usage, model and other conditions.

| Setting choice | Samsung’s stated runtime estimate | Trade-off |
|---|---|---|
| Always On Display on | Up to 60 hours in normal battery mode, with both power-saving modes off | The screen remains glanceable; the estimate is lower. |
| Always On Display off | Up to 80 hours under the same stated conditions | Longer estimated runtime, but the display is not continuously visible. |
Those estimates are from Samsung Electronics’ Galaxy Watch Ultra product documentation accessed in 2026. Samsung says actual battery life may vary with usage patterns, device model and battery manufacturer. Start with normal behavior, observe your own use for a day or two, then decide whether to switch off Always On Display or use a power-saving mode.
Crashes, No Sound, or Screen Glitches?

Power saving may restrict CPU speed, background network use and location services, and may disable Wi-Fi, wake-up gesture and other features. That can make sense when extending runtime matters more than those functions; it is not simply a battery boost with no change to watch behavior. Exercise power saving is a separate mode, so note whether it is on when comparing your own battery experience with Samsung’s normal-mode estimates.

2. Keep wrist notifications useful
Allow alerts from apps that genuinely benefit from appearing on your wrist, and disable low-value interruptions. Calls, messages, calendar reminders and activity alerts are possible choices, not a universal recommended list: keep the ones that help you and mute the rest.
Notification preferences depend on the paired phone, apps and software version. Samsung’s product documentation describes Android/Galaxy Wearable pairing but does not prescribe one ideal notification list. Use the notification controls in Galaxy Wearable or the watch settings available on your setup, and check the labels shown on your device rather than relying on a path that may differ by version.
3. Configure the Quick Button for your main activity
Assign the Quick Button to the activity or control you expect to use most. If you want it to control Multisport, Samsung says you must configure that option in Quick Button settings. This is an activity-specific setup choice, not a reason to enable every workout feature.

If you hike or cycle, set up Track Back each time
Samsung says Track Back must be enabled in Samsung Health settings before each hiking or cycling workout session. Do not assume that configuring the Quick Button also turns on Track Back; they are separate setup actions.
4. Match activity and water use to the watch’s limits
Samsung describes the Galaxy Watch Ultra as suitable for shallow-water swimming, but its water-resistance ratings do not mean it is suitable for every water activity. Samsung states that the watch is water resistant for 10 minutes at 100 meters under ISO 22810 testing, and has an IP68 rating for submersion in fresh water up to 1.5 meters for up to 30 minutes under the stated lab conditions. These are test conditions, not permission for high-pressure water use or diving.
Samsung’s guidance is explicit: “Galaxy Watch Ultra is not suitable for high-pressure water activities and diving.” It also says, “Water resistance is not a permanent condition and can diminish over time.” Treat the ratings as bounded conditions, not a guarantee that resistance will remain unchanged or cover every use.

5. Review health features with compatibility in mind
Separate general wellness tracking from restricted features
Health and wellness measurements can be useful for personal reference, but they are not universal medical diagnostics. Samsung says Galaxy Watch Ultra features may vary by compatible smartphone, region and carrier. The listed phone experience requires Android 11 or later and at least 1.5 GB of memory. Samsung Health Monitor is available only on Samsung Galaxy smartphones; ECG, irregular-heart-rhythm notifications and blood-pressure functions are also subject to country and region approval and availability restrictions.
Do these 3 things before closing this tab:
1Fix the driver behind crashes, sound loss and screen glitches2Repair Windows errors before they cause bigger problems3Scan for outdated or missing drivers - takes under a minuteKnow the blood-pressure calibration requirement
Samsung says its blood-pressure feature requires calibration every four weeks using a blood-pressure monitor and arm cuff. Check that the feature is available for your phone and location before relying on it, and follow Samsung’s calibration requirements if you use it.
Samsung says health measurements are for personal reference and are not intended to diagnose or treat a condition or replace professional medical advice. Do not take clinical action based only on watch output; consult a qualified health professional about health concerns.

6. Check emergency readiness and privacy
Set realistic expectations for emergency contact alerts
Review the emergency contacts and emergency features available on your watch and phone, then confirm that their behavior fits your needs. Samsung says notifying an emergency contact requires a network connection, and GPS accuracy can be affected by obstructions. A watch feature should not be treated as a substitute for reliable access to emergency services.
Samsung’s product documentation lists a siren rated up to 86 decibels and up to 180 meters. Those are stated maximums; Samsung says loudness and range vary by environment, and activation duration may depend on battery.
Consider a screen lock
A screen lock is a sensible privacy measure for a device that may hold personal health information. Review the lock options and instructions shown for your software version in the Galaxy Watch Ultra manual; menu labels and supported choices can vary.

Check compatibility and the current manual
Samsung’s support page links an English Galaxy Watch Ultra user manual for OS 6.0, version 1.1, dated August 5, 2025. Use the manual that matches your watch’s software and region when following exact steps. Samsung also notes that features may vary by phone, region and carrier, so confirm local availability before depending on a feature.
