What makes a smartwatch last longer?
“Lasts longer” can mean two different things: the watch keeps working physically, or it remains useful because its battery, software, and phone compatibility still meet your needs. Treat these as separate checks. A water-resistance rating does not establish repairability, and a manufacturer’s software updates do not prevent battery wear.

There is no evidence here to rank smartwatch brands by lifespan or to predict how many years a particular model will last. Battery aging and physical wear depend on use, settings, damage, and care; update terms also vary by product.

Battery runtime is not the same as battery lifespan. Apple says battery lifespan varies with use and settings, and that Optimized Battery Charging can reduce battery wear by limiting how long Apple Watch stays fully charged. That guidance is specific to Apple Watch; it is not a guarantee of a fixed lifespan. See Apple Watch Battery and Performance.

Before choosing any model, find out whether its maker offers battery service for that exact watch in your region, and what to do if an aged battery affects performance. Apple documents battery service and directs users with battery performance concerns to support at Batteries – Service and Recycling. Service terms may differ by model and location. The available manufacturer guidance does not establish a universal owner-replaceable battery policy across smartwatch brands.
- Consider how often you are willing to charge and whether the watch’s runtime suits your routine.
- Look for battery-care features, but treat them as ways to manage wear rather than promises about how long the battery will last.
- Confirm the service route for the exact model and your country before purchase.
Verify software and security support for the exact model
Updates can affect how long a watch remains secure and compatible with the services you use. Check what the maker says about software and security updates, which devices are covered, and when the stated period starts. Do not assume every model from one brand gets the same support.

Google says applicable Fitbit devices receive security updates for at least two years after the device was last sold through Fitbit.com or the Google Store. The clock starts at last sale through those stores, not necessarily the date you buy the device. This commitment is specific to applicable Fitbit devices; it should not be generalized to every Fitbit product or other smartwatch brands. Check Google’s Fitbit security update information for device eligibility.
Garmin maintains an official resource for wearable software updates, but the resource does not establish one support duration for every Garmin watch. Check the specific device and its update information at Garmin’s wearable software update page.

Samsung says Galaxy Watch and Fit water resistance is not permanent and may deteriorate over time. Its support guidance, dated 2025-05-27, gives 5 ATM and 10 ATM figures for named Galaxy Watch generations and describes standardized tests, including still freshwater conditions.

Account for knocks, abrasion, and care
Think about where and how you will wear the watch. Frequent knocks, scraping, or exposure to substances that can degrade water resistance may affect its condition. Garmin publishes watch care tips with cautions about substances that may degrade water resistance; consult the instructions for your device before cleaning or exposing it to chemicals.

Make sure it will remain useful with your phone
A working watch can still stop meeting your needs if it no longer supports your phone or essential functions. Before buying, verify compatibility with your current phone and check whether the features you depend on require a particular operating system, app, account, or connected service. Consider whether you expect to keep that phone ecosystem for the same period as the watch.
Use this checklist to compare models
- Battery and service: Does the runtime fit your routine? What battery-care features are available, and can the manufacturer service this exact model in your region?
- Software and security: Which updates are covered, for which model, and for what stated period or starting point?
- Water and activity fit: Do the model’s instructions allow your planned activities, and what care is required after exposure?
- Impact and wear: Will the watch face the knocks, abrasion, or substances expected in your daily use? Treat protective accessories as limited aids, not guarantees.
- Phone and features: Does it work with your phone and the functions you need now, and is that ecosystem likely to remain suitable for you?
Compare the exact model numbers, not just brand names or product families. Manufacturer support pages are the best place to confirm current service, compatibility, update, and activity terms for your region.
