Amazfit Active 2 vs Apple Watch SE 3

Amazfit Active 2

A 1.32-inch round AMOLED at 466 x 466 resolution with a 2,000-nit peak — brightness that genuinely matches flagship watches and stays readable in direct sunlight. Always-on display is supported. One quirk: the screen will not reach full brightness below 30% battery.

• 1.32-inch AMOLED, 466 x 466 resolution, with a 2,000-nit peak brightness — premium-watch territory at a budget price.
• The 2,000-nit panel matches premium watches like the Apple Watch — easily readable in direct sunlight.
• DesFit: 'a good display where it gets plenty bright... tons of colors as well as tons of contrast.'
• Always-on display is supported — though enabling it roughly halves battery life.
• Quirk: the screen will not reach full brightness when the battery drops below 30% — an odd, documented limitation.

Apple Watch SE 3

The big SE 3 story: an always-on display, a first for the SE line. The LTPO OLED panel peaks at 1,000 nits — bright enough for everyday use, but half the Series 11's 2,000 nits and a third of the Ultra 3's 3,000.

• Always-on display arrives on the SE for the first time — Origin Disc: 'that alone is a huge upgrade for the SE line.'
• LTPO OLED panel peaks at 1,000 nits — fine for everyday use but dimmer than rivals.
• 1,000 nits is half the Series 11's 2,000 and a third of the Ultra 3's 3,000 — the SE 3's display is its clearest hardware compromise.
• Always-on is a personal-preference feature — some owners prefer to leave it off for extra battery life.

Amazfit Active 2

BioTracker optical heart rate, SpO2, HRV, skin temperature, plus compass, barometer and altimeter. Resting HR and step counting are accurate; high-intensity HR drifts and sleep-stage accuracy is mediocre versus a reference device. There is no ECG and no blood-pressure sensor.

• Resting heart rate, HRV and step counting tested as accurate in everyday use.
• Full sensor suite for the price — SpO2, HRV, skin temperature, plus compass, barometer and altimeter.
• EvoGrid found wrist heart-rate readings 'lined up closely with what I saw on more expensive watches.'
• The Quantified Scientist, using a Polar H10 ECG chest strap as reference, found heart rate could sit roughly 10 bpm above or below the true value for stretches.
• Sleep-stage accuracy is weak — The Quantified Scientist measured only ~55% deep-sleep agreement and ~34% REM agreement against a reference device.
• No ECG and no blood-pressure sensor — not surprising at $100, but it caps the health story.

Apple Watch SE 3

Heart rate is the SE 3's standout — testers rate it among the best wrist sensors available. Apple adds nightly wrist-temperature tracking and sleep apnea notifications. But ECG, blood oxygen (SpO2), and the Series 11's new hypertension alerts are all absent, and sleep-stage data underreports deep sleep.

• Heart-rate accuracy is excellent — Mike O'Brien tested it against a Polar H10 ECG chest strap and found it had the second-highest correlation of the watches tested, behind only the Pixel Watch 3.
• The Quantified Scientist rates the Apple Watch's optical heart-rate sensor as the best wrist HR monitor he has tested — the SE 3 inherits it.
• No ECG sensor — confirmed missing; if heart-rhythm ECG matters to you, you need the Series 11 or Ultra 3.
• No blood-oxygen (SpO2) sensor and no hypertension notifications — the Series 11's headline health features are absent.
• Apple adds nightly wrist-temperature tracking — the watch samples skin temperature roughly every 5 seconds overnight.

Amazfit Active 2

160+ sport modes including HYROX, automatic detection of 25 exercises, and a Readiness score with recovery guidance. GPS distance tracking is reliable and gets a fix in seconds; high-zone heart rate during intense workouts is the weak link.

• 160+ sport modes, including a dedicated HYROX race mode — far more than typical budget watches.
• Automatic workout detection covers 25 exercises and kicks in within about 4 minutes — quicker than many rivals.
• DesFit on running GPS: distance 'compared well against tons of other devices' and the track was 'right in line with all the other devices.'
• Includes a Readiness score, training load and a recovery advisor — features rarely seen on a $100 watch.
• Chase the Summit found heart rate overestimating by about 20 bpm in Zone 4 on one hard run versus an ECG chest strap, while a later run nearly matched it bang-on.
• Can pair an external Bluetooth heart-rate chest strap for workouts — one owner runs ~2 hours daily with a chest strap connected.

Apple Watch SE 3

The full watchOS workout app, activity rings, automatic workout detection, and built-in GPS. Apple rates about 7 hours of GPS workout tracking. It is not a dedicated running watch — no dual-frequency GPS — but for everyday fitness it covers the essentials well.

• Full watchOS workout app, activity rings and automatic workout detection — everything expected of an Apple Watch.
• Built-in GPS rated for about 7 hours of workout tracking — DesFit found real-world endurance well beyond that claim.
• The Quantified Scientist rates the Apple Watch SE as a pretty good GPS tracker — accurate enough for everyday runs and rides.
• Not a dedicated running watch — no dual-frequency GPS and no deep training analytics; serious runners still look to Garmin or the Ultra 3.
• Crash detection, fall detection and Emergency SOS carry over — Mike O'Brien notes fall detection is 'among the best in the industry.'

Amazfit Active 2

Amazfit rates the 270mAh cell at 10 days typical and 5 days heavy use. Real-world testing confirms a genuine 10 days on default settings and roughly 4-5 days with always-on display and every sensor enabled. A battery-saver mode stretches it toward three weeks. Charging takes about 2 hours via a magnetic puck and USB-C; there is no wireless charging.

• Genuine 10 days on default/typical settings — testers consistently hit Amazfit's headline claim.
• With the always-on display and all health features on, real-world life drops to roughly 4-5 days.
• EvoGrid got around 7-10 days with notifications, tracked workouts and sleep monitoring on.
• A battery-saver mode reduces sensor frequency and stretches life toward 19 days — useful for travel.
• Roughly 21 hours of continuous GPS on a single charge — solid endurance for runs and rides.
• Charges fully in about 2 hours via a magnetic puck and USB-C cable; the last few percent are slow, and there is no wireless charging.

Apple Watch SE 3

Apple still rates the SE 3 at 18 hours of all-day battery, and that conservative number holds — but independent endurance tests stretched it to 37-41 hours of continuous wear depending on size. The genuine upgrade is fast charging: roughly 0-80% in 45 minutes, with a 15-minute top-up buying about 8 hours. A low-power mode reaches ~32 hours.

• Fast charging is new to the SE line — about 0-80% in 45 minutes, matching Apple's claim in testing.
• A 15-minute top-up buys roughly 8 hours of use — enough to rescue a sleep-tracking night.
• Endurance test: the 44mm SE 3 ran ~41 hours of continuous wear and the 40mm ~37-38 hours — far beyond Apple's conservative 18-hour rating.
• Still rated 18 hours — fast charging helps, but daily charging is the reality, and you may need a pre-bed top-up for sleep tracking.
• A low-power mode extends life to roughly 32 hours on a single charge.

Amazfit Active 2

Zepp OS on the watch and the Zepp companion app, with a built-in speaker and microphone for calls and offline maps with navigation. It works with both iPhone and Android. Software is the watch's weak spot — functional but rough versus Garmin or Wear OS — though Amazfit ships ongoing updates that add features over time.

• Cross-platform — pairs with both iPhone and Android via the Zepp app.
• Built-in speaker and microphone handle calls from the wrist; offline maps with navigation are built in — rare at this price.
• Software is the budget showing through — owners say the watch and app 'need significant improvement, especially when compared to Garmin or Coros.'
• Performance is snappy — early owners were 'impressed by how snappy the system is'; it is not Apple-Watch-smooth but never feels sluggish.
• Amazfit ships ongoing updates — a post-launch firmware update added the Bio Charge energy metric and refined the sleep-score algorithm.
• Tight internal storage limits maps and music — there is under 200MB available to the user, and owners report having to delete content to fit updates.

Apple Watch SE 3

watchOS 26 on Apple's S10 chip — identical core performance to the Series 11 and Ultra 3, including double-tap and wrist-flick gestures. 64GB of storage. Apple Pay, the App Store and the full ecosystem are all here. The one hard limit: it works only with an iPhone.

• Same S10 chip as the Series 11 and Ultra 3 — TheJuan&Only confirms identical core performance across the lineup.
• Supports the S10-enabled gestures — double-tap and wrist-flick to dismiss notifications.
• 64GB of storage and the full App Store, Apple Pay, Find My and Siri — nothing core is cut from the experience.
• iPhone-only — like every Apple Watch, the SE 3 does not work with Android phones.
• TechRadar: it has 'the same fantastic chipset as the Ultra 3 and Series 11' — the SE 3 doesn't feel slow or cut-down in daily use.

Amazfit Active 2

Rated to 5 ATM (50m), fine for pool and open-water swimming. The Premium model is protected by a sapphire-crystal lens — the same material Garmin uses on its $1,000-plus watches — while the Standard model uses tempered glass.

• 5 ATM (50m) water resistance — rated for pool and open-water swimming.
• The Premium model uses a sapphire-crystal lens — the same scratch-resistant material Garmin puts on its high-end Fenix watches.
• The cheaper Standard model is protected by tempered glass instead of sapphire — reviewers widely call the $30 sapphire upgrade worth it.
• Stainless-steel case construction adds to the durable, premium feel for the price.

Apple Watch SE 3

Crack-resistant Ion-X glass, now rated about 4x tougher than the SE 2, over an aluminum case. Water resistance is 50m (5 ATM) — fine for pool and open-water swimming.

• 50m (5 ATM) water resistance — rated for pool and open-water swimming.
• Crack-resistant Ion-X glass, now about 4x more crack- and scratch-resistant than the SE 2.
• DesFit notes Apple Watch aluminum models hold up well in practice — he has scratched only one across many Apple Watches going back to the Series 3.
• Not as scratch-hardened as the Series 11's ceramic-coated glass or the Ultra 3's sapphire — fine for everyday wear, not adventure abuse.

Amazfit Active 2

Built-in single-band GPS across five satellite systems, Bluetooth 5.2, and Zepp Pay contactless payments on the Premium model. There is no LTE option, so the watch relies on a paired phone for connectivity.

• Built-in GPS spans GPS, GLONASS, Galileo, BeiDou and QZSS — but it is single-band, so there is no dual-frequency precision.
• GPS locks a fix quickly — DesFit measured about 5-10 seconds to acquire a satellite signal at the start of an activity.
• GPS distance held up against a dedicated Garmin running watch — 7.6km versus the Garmin's 7.7km over the same route in built-up central London.
• Zepp Pay contactless payments are included on the Premium model; the Standard model omits NFC payments.
• No LTE option — reviewers flag the lack of a cellular version as one of the few feature gaps.

Apple Watch SE 3

Built-in GPS, Apple Pay via NFC, Bluetooth and Wi-Fi. An optional cellular model adds standalone connectivity for about $50 more. The SE 3 lacks the Series 11's second-generation ultra-wideband chip, so it can only ping a lost iPhone rather than guide you to it.

• Built-in GPS, Apple Pay (NFC), Bluetooth and Wi-Fi — the standard Apple Watch connectivity set.
• An optional cellular model adds standalone connectivity for roughly $50 more — useful for leaving the phone behind.
• No second-generation ultra-wideband chip — the SE 3 can only beep a lost iPhone, not precision-guide you to it like the Series 11.

Amazfit Active 2

At $99 for the Standard and $129 for the sapphire-glass Premium, the Active 2 undercuts almost everything with comparable hardware. The trade is software depth: an Apple Watch SE or a Garmin gives you a more mature ecosystem and stronger analytics, but charges far more and — in the Apple Watch's case — lasts a fraction as long.

• Digital Trends' verdict is in the headline: 'the best $100 smartwatch you can buy.'
• The Verge calls the Active 2 'one of the best fitness trackers you can buy.'
• vs Apple Watch SE: the Active 2's ~10-day battery dwarfs the SE's roughly 18-hour life, though the SE wins on app ecosystem and tight iPhone integration.
• vs Garmin: Garmin owners debating the jump concede Amazfit is 'good enough' for many — Garmin wins on software and analytics depth, the Active 2 wins decisively on price.
• Best for: anyone who wants a great-looking, long-lasting fitness watch at a budget price and treats deep analytics and app polish as bonuses.

Apple Watch SE 3

At a held-steady $249, the SE 3 is the cheapest way into a current Apple Watch and the obvious pick for most iPhone owners. The $399 Series 11 adds ECG, blood oxygen, hypertension alerts, a brighter screen and 24-hour battery; the $799 Ultra 3 adds far more. For the majority, the SE 3's gaps will not be felt.

• TechRadar's verdict: the SE 3 'might be the best-value Apple Watch ever made.'
• Mike O'Brien calls it 'the best Apple Watch for most people' — major improvements with very few noticeable differences from the $400 Series 11.
• Gizmodo: 'The Apple Watch SE 3 is a stupidly good value for $250.'
• Step up to the $399 Series 11 for ECG, blood oxygen, hypertension alerts, a 2,000-nit screen and 24-hour battery — worth it only if you actually need those.
• Best for: first-time Apple Watch buyers and anyone who wants the core experience for the lowest price — Tom's Guide names the SE 3 'the best value, great for first-time users.'
