How Long Will My Garmin Smartwatch Battery Last?

Answer: Longer than most other smartwatch brands.

If you have to charge your smartwatch every night while you sleep, your smartwatch is falling short. If your smartwatch battery life lasts only a day — or even just a couple — you’re missing out on tracking your body’s physiological metrics while you charge it. This means you’re getting a less accurate picture of your overall health and fitness status, not to mention missing out on the smart notifications you’ve come to rely on while it’s off your wrist and on the charger.

Luckily for you, Garmin watch batteries last a long time — and we mean a long time. At minimum, Garmin fitness and outdoor watches should be getting about a week of battery life before having to recharge, and at maximum you could be getting up to 50 days. (No, that is not a typo – the Garmin Enduro™ boasts up to 50 days in smartwatch mode — or 65 if you’re using solar charging.) It all depends on the features that are important to you and the watch that best fits your lifestyle. If battery life is important to you (and we bet it is), below we’ve listed each of our smartwatch models and their corresponding battery life capabilities.

Note: It’s important to know that this chart only depicts smartwatch mode. If your specific watch has other capabilities like built-in GPS, battery conservation functionality and more, those numbers may look different.
