Amazfit Active 2 (Round)
Pick Amazfit Active 2 (Round) for a slim, round watch at $99.99–$129.99: a 1.32-inch AMOLED in a 9.9mm-thick case, with sapphire on Premium.
In short
Pick Amazfit Active 2 (Round) for a slim, round watch at $99.99–$129.99: a 1.32-inch AMOLED in a 9.9mm-thick case, with sapphire on Premium. It lasts up to 10 days between charges, or 21 hours with GPS running, and tracks sleep, skin temperature and a daily readiness score. For dual-band GPS, 10 ATM or 64GB of storage, you'll need Balance 3, at $369.99 to $449.99.

Who it is for
- Anyone who wants a smartwatch that passes for a regular watch: a 43.9mm round case, 9.9mm thick, with a stainless steel bezel.
- Sleep and recovery trackers. Its sleep tracking includes REM, breathing quality and HRV, and it adds a daily readiness score.
- Gym and running regulars. Amazfit lists 164 sports modes, including HYROX Race, plus Track Run with a virtual pacer and Zepp Coach.
Who should skip it
- Anyone who'd trade the round look for more screen and battery. Amazfit's cheaper Bip has a bigger screen and a longer battery rating.
- Divers and backcountry hikers. Active 2 is rated 5 ATM with five-system GPS; T-Rex 3 steps up to 10 ATM and dual-band GPS in a rugged case.
What sets it apart
- A sharp round screen: 1.32 inches and 466 × 466 pixels (353 ppi), rated up to 2,000 nits in Amazfit's product copy.
- Thin and light: 9.9mm thick, and 29.5 grams (Standard) or 31.65 grams (Premium) without the strap.
- A stainless steel bezel on both versions, and sapphire over the screen on Premium.
- Sensors that aren't in the cheaper Bip's list: a barometric altimeter and skin temperature, next to BioTracker 6.0 heart-rate tracking.
Caveats
- Battery life is modest: 10 days of typical use drops to 5 under heavy use.
- Bluetooth 5.2 is the only connection Amazfit lists, so don't expect Wi-Fi, and Membership Cards stand in for contactless payments.

Small, round and sharp
Active 2 Round is built to look like a watch first. The case is 43.9mm across and 9.9mm thick without the sensor base, with a stainless steel bezel over a polymer middle frame, and it weighs 29.5 or 31.65 grams before the strap, depending on the version. The 1.32-inch AMOLED packs 466 × 466 pixels into that circle, or 353 ppi, and Amazfit’s product copy claims up to 2,000 nits.
Premium covers the screen in sapphire; Standard uses coated tempered glass. Both take 20mm quick-release straps, so the strap that comes in the box doesn’t have to be the one you keep.
Battery and charging
| Mode | Active 2 Round |
|---|---|
| Typical use | Up to 10 days |
| Heavy use | Up to 5 days |
| Battery saver | Up to 19 days |
| Continuous GPS | Up to 21 hours |
That comes from a 270mAh battery. Typical use gets you through a normal week with room to spare; a week of daily GPS workouts and constant notifications will want a midweek top-up. Filling it from empty takes about 2 hours on the magnetic base.
Health, sleep and training
BioTracker 6.0 follows your heart rate around the clock and alerts you to unusually high or low readings. Blood oxygen and skin temperature are tracked all day too. Sleep tracking covers stages, naps, breathing quality and HRV against a sleep schedule, with a score for each night, and the daily readiness score comes with insights.
For training, Amazfit lists 164 sports modes, Track Run with a virtual pacer, Zepp Coach, and HYROX Race among the indoor workouts.
Active 2 Round or Balance 3?
Balance 3 is a different budget at $369.99 to $449.99, but it’s where to look if Active 2 runs out of road. It has a brighter 3,000-nit screen, a 658mAh battery good for 21 days of typical use or 41 hours of its most accurate GPS, dual-band GPS, 10 ATM, 64GB of storage, Wi-Fi, a flashlight and Bluetooth calls. Active 2 is smaller, lighter and a fraction of the price.
Going the other way, Amazfit’s cheaper Bip swaps the round case for a bigger rectangular screen and a longer battery rating, and it takes Bluetooth calls.
Price
On 19 September 2026, Amazfit’s US store priced Active 2 Round at $99.99 to $129.99, a range that spans Standard and Premium. Make sure the listing you’re looking at is the version you want before you buy.

Frequently asked questions
Should I get Active 2 Standard or Premium?
Premium, if you want sapphire over the screen and a leather strap. Standard pairs anti-fingerprint-coated tempered glass with a silicone strap, and weighs 29.5 grams to Premium's 31.65 without the strap. Mind the strap sizes: the silicone fits 135–195mm wrists, the leather 150–210mm.
Can Active 2 take phone calls?
Not that Amazfit lists. Bluetooth calling is in Balance 3's specs but not Active 2's, so plan on answering calls on your phone.
Does Active 2 work with an iPhone?
Yes: any iPhone on iOS 14 or later works, as does an Android phone on Android 7 or later, through the Zepp app.
Does Active 2 have an altimeter?
Yes, a barometric one. It sits alongside an accelerometer, a gyroscope, a geomagnetic sensor, an ambient light sensor and a temperature sensor.
