Charging a smartwatch every night gets old fast. It’s also the number one reason people quit wearing one, and nobody can track their sleep with a watch sitting on the charger. If that sounds familiar, the watches below last days or weeks between charges.
| Watch | Claimed battery (typical use) | Works with | Best for |
|---|---|---|---|
| Withings ScanWatch 2 | About a month | iPhone and Android | Looks like a classic watch |
| Amazfit Balance 2 | Up to about 3 weeks | iPhone and Android | All-round value |
| Amazfit Bip 6 | Up to about 2 weeks | iPhone and Android | Budget pick |
| Garmin Instinct solar | Weeks, longer with solar | iPhone and Android | Outdoor and rugged |
| Pebble Core Time 2 | Weeks | iPhone and Android | Simple, distraction-light smartwatch |
| Apple Watch Ultra | About two days or more | iPhone only | Longest-lasting Apple Watch |
Every number here is a maker’s claim. Bright always-on screens, GPS workouts and music will cut them down, sometimes a lot.
Longest battery overall: Withings ScanWatch 2
It looks like a regular analog watch with real hands, hides a small screen for stats, and runs around a month per charge. It tracks heart rate, sleep and steps and can take an ECG reading. You give up apps and fancy notifications. Great for people who want a nice watch first and a smartwatch second.
Best all-rounder: Amazfit Balance 2
A real smartwatch with GPS, maps, a great AMOLED screen and solid health tracking, lasting up to around three weeks. It doesn’t have the app store of an Apple or Samsung watch, but it does the everyday stuff well and almost never needs charging.
Best budget pick: Amazfit Bip 6
Up to two weeks of battery, GPS and a big bright screen for under $100. It’s the easiest recommendation on this list. We cover more cheap options in our best smartwatches under $100 guide.
Best rugged pick: Garmin Instinct
Garmin’s tough outdoor watch lasts weeks, and solar versions stretch that even further in sunny conditions. Navigation, weather alerts and training tools are excellent. It’s chunky and looks like adventure gear, which is either a plus or a no-go.
Best simple smartwatch: Pebble
The Pebble name is back with watches built around low-power screens, physical buttons and multi-week battery life. They’re a lovely fit for people who want notifications and basic tracking without a tiny phone strapped to their wrist.
If you need an Apple Watch: Apple Watch Ultra
No Apple Watch lasts weeks, but the Ultra goes about twice as long as the others. If you’re on iPhone and want Apple’s features, it’s your best bet for charging less. See how to choose an Apple Watch for the full lineup.
How to make any watch last longer
Turn off the always-on display, lower the brightness, limit which apps can send notifications, and switch heart rate tracking from continuous to periodic if your watch allows it. GPS workouts drain the most, so leave GPS off for indoor sessions.
FAQ
Which smartwatch has the longest battery life?
Hybrid watches like the Withings ScanWatch 2 last around a month. Among full smartwatches, Amazfit and Garmin models last weeks.
Which Apple Watch has the best battery life?
The Apple Watch Ultra lasts the longest, roughly two days or more of typical use.
Why do some smartwatches last weeks and others only a day?
Watches with bright screens, full app stores and powerful chips use far more power. Simpler software and efficient screens stretch battery life a lot.
Does GPS drain smartwatch battery?
Yes. GPS tracking is one of the biggest drains, along with always-on displays and music playback.
Is a long-battery smartwatch good for sleep tracking?
Yes. If you don’t have to charge it at night, you’ll actually wear it to bed, which makes the sleep data much more useful.
