Quick Verdict
The Amazfit Bip 6 (46mm) wins by 0.1 points, which is not enough to settle it. FDA-cleared heart features for $249 — the best-value Apple Watch, with the worst battery here. Pick on the specs that matter to you, not the overall score.
The Apple Watch SE 3 (40mm, GPS, Aluminum) and Amazfit Bip 6 (46mm) are both current-generation smartwatch models, and the Amazfit Bip 6 (46mm) is $169 cheaper than the Apple Watch SE 3 (40mm, GPS, Aluminum) ($79.99 vs $249). On Ecosystem Freedom, the Amazfit Bip 6 (46mm) leads (9.0 vs 1.0/10) — the category's trap dimension: how much of the watch still works on a phone other than the maker's own. 10 means full parity on iOS and Android; 1 means one phone brand or nothing. On App Ecosystem, the Apple Watch SE 3 (40mm, GPS, Aluminum) leads (10.0 vs 2.5/10) — whether there is a real third-party app store on the wrist or a handful of proprietary mini-apps. On Battery Life, the Amazfit Bip 6 (46mm) leads (9.4 vs 4.5/10) — real endurance between charges, judged against what the claim actually assumes rather than the headline number. Overall, the Amazfit Bip 6 (46mm) scores 7.1/10 across our 8 scoring categories versus 7.0/10 for the Apple Watch SE 3 (40mm, GPS, Aluminum), though the gap is close enough that your specific use case should decide it. Below, we break down the full spec sheet, category-by-category scores, and exactly who should buy which one.
Side-by-Side Comparison
| Spec | Apple Watch SE 3 (40mm, GPS, Aluminum) | Amazfit Bip 6 (46mm) |
|---|---|---|
| Price | $249.00 | $79.99 |
| Release Year | 2025 | 2025 |
| Phone Compatibility | iPhone only. Requires iPhone 11 or later running iOS 26 or later. No Android support of any kind. | Both iOS and Android, with no feature gated to a particular phone brand. Amazfit makes no phones, so there is no lock-in — the one genuinely neutral tier of this category. Camera control is iPhone-only. |
| Claimed Battery Life (hrs) | 18 | 336✓ |
| What the Battery Claim Assumes | Apple's 18 h figure assumes the same mixed-use day as Series 11 (90 time checks, 90 notifications, 15 min app use, 60 min workout) with the always-on display active and no LTE. Add overnight sleep tracking and you are charging twice a day. | Amazfit's 'up to two weeks' figure is a typical-use claim with the always-on display OFF, notifications on and no continuous GPS. Turning on the always-on display or tracking daily GPS workouts cuts it to a handful of days. Amazfit does not publish a mAh capacity in the press materials. |
| Case Size (mm) | 40 | 46 |
| Display | LTPO OLED, always-on (new to the SE line), up to 1000 nits | 1.97-inch AMOLED, up to 2000 nits |
| Operating System | watchOS 26 | Zepp OS (proprietary) |
| Third-Party Apps | Full on-device App Store — identical native watchOS catalogue to Series 11 and Ultra 3 | Closed proprietary Zepp OS app store — a small curated list of mini-apps and watch faces, nothing like a Play Store or App Store. Do not expect your bank, your podcast player or your transit app. |
| Health Features Enabled in the US | Live in the US: ECG, irregular rhythm notifications, sleep apnea notifications and hypertension notifications (FDA-cleared), plus wrist temperature. Blood Oxygen uses the same post-Masimo design as Series 11 — captured on the watch, calculated on the iPhone. There is no depth gauge and no skin-temperature-driven ovulation estimate beyond what Series 11 offers. | BioTracker 6.0 optical heart rate, SpO2, stress and HRV. No ECG, no FDA-cleared feature, no blood pressure. Everything here is wellness-grade estimation. |
| Subscription Wall | None required; Apple Fitness+ ($9.99/mo) is optional. | Core tracking is free. Zepp Aura — the AI sleep and meditation layer — is $11.99/mo or $69.99/yr after a 14-day trial; the free tier caps you at one AI assistant message per day and withholds the weekly and monthly sleep analyses. |
| LTE Option | Separate SKU: Apple lists SE 3 GPS + Cellular at a $50 upcharge and it needs its own carrier line. The cellular 40mm has repeatedly been discounted to $249.99 at Amazon, closing the gap. | None — no cellular variant exists. |
| Water & Dust Rating | 50 m water resistant (WR50), IP6X dust resistant | 5 ATM (50 m) |
| Battery Replacement | Apple out-of-warranty battery service is a flat $99 — over a third of the watch's price. | Amazfit publishes no consumer battery-replacement service; at $79.99 the watch is effectively disposable. |
| Warranty | 12 months | 12 months |
| Colors | Midnight, Starlight | Black, Charcoal, Stone, Red |
Category Scores
Battery Life
The Amazfit Bip 6 (46mm) leads clearly here, 9.4 against 4.5 — a 4.9-point margin on real endurance between charges, judged against what the claim actually assumes rather than the headline number. If that is what you are buying for, the Apple Watch SE 3 (40mm, GPS, Aluminum) does not close the gap elsewhere.
Health Tracking
The Apple Watch SE 3 (40mm, GPS, Aluminum) leads clearly here, 8.8 against 5.0 — a 3.8-point margin on depth of heart, sleep and body metrics that are genuinely enabled and cleared for use in the US. If that is what you are buying for, the Amazfit Bip 6 (46mm) does not close the gap elsewhere.
Fitness & GPS
The Apple Watch SE 3 (40mm, GPS, Aluminum) leads clearly here, 7.8 against 7.2 — a 0.6-point margin on workout tracking, GPS accuracy, sport modes and training analysis. If that is what you are buying for, the Amazfit Bip 6 (46mm) does not close the gap elsewhere.
Ecosystem Freedom
The Amazfit Bip 6 (46mm) leads clearly here, 9.0 against 1.0 — a 8.0-point margin on the category's trap dimension: how much of the watch still works on a phone other than the maker's own. 10 means full parity on iOS and Android; 1 means one phone brand or nothing.

App Ecosystem
The Apple Watch SE 3 (40mm, GPS, Aluminum) leads clearly here, 10.0 against 2.5 — a 7.5-point margin on whether there is a real third-party app store on the wrist or a handful of proprietary mini-apps. If that is what you are buying for, the Amazfit Bip 6 (46mm) does not close the gap elsewhere.
Display
The Amazfit Bip 6 (46mm) is marginally ahead, 7.8 to 7.4. A gap this small rarely decides a purchase on its own, though it counts if panel type, brightness, always-on behaviour and legibility in sunlight is your priority.
Build & Durability
The Apple Watch SE 3 (40mm, GPS, Aluminum) leads clearly here, 7.6 against 6.2 — a 1.4-point margin on case and glass materials, water and dust ratings, and how well it survives daily wear. If that is what you are buying for, the Amazfit Bip 6 (46mm) does not close the gap elsewhere.
Value
The Amazfit Bip 6 (46mm) leads clearly here, 9.6 against 9.0 — a 0.6-point margin on what you get for the money once LTE upcharges and subscriptions are counted in. If that is what you are buying for, the Apple Watch SE 3 (40mm, GPS, Aluminum) does not close the gap elsewhere.

Apple Watch SE 3 (40mm, GPS, Aluminum)
Pros

- +No subscription gates any metric, unlike the similarly-priced Fitbit Sense 2
Cons

- +A 2000-nit AMOLED, GPS with offline maps and two weeks of battery, all for $79.99
