Side-by-Side Comparison
| Spec | Amazfit Helio Ring (2024) | RingConn Gen 2 Air (2025) |
|---|---|---|
| Price | $149.99 | $199.00 |
| Release Year | 2024 | 2025 |
| Battery Life (claimed) (days) | 4 | 10✓ |
| Battery, In Practice | Amazfit publishes 'up to 4 days' — the shortest claim in this comparison, and it is the headline figure, so continuous SpO2 and temperature sensing pull it down from there. Wireless charging takes about 1 hour 40 minutes. | RingConn publishes 'up to 10 days'. There is no vibration motor and no apnea engine running overnight, which is part of why it holds up. Full charge takes about 90 minutes; the ring stores 5-7 days of data offline if you do not open the app. |
| Subscription | None. Amazfit states no subscriptions are required, and Zepp Aura Premium (sleep sounds, detailed sleep reports, AI chat) is included free rather than sold separately. | None. Everything the ring measures is free — but note that what it measures is a shorter list than the Gen 2, because sleep-apnea monitoring is removed. |
| 3-Year Cost of Ownership ($) | 149.99✓ | 199 |
| Sizes Offered | Three sizes only — 8 (24mm), 10 (25.7mm) and 12 (27.3mm). If your finger falls between them, there is no ring for you; every rival here offers seven to twelve sizes. | US 6-14, no half sizes; RingConn sizing differs from standard US ring sizes |
| Sizing Kit | Not offered in the way rivals do it — with only three sizes Amazfit publishes inner diameters instead. That removes the kit wait but makes a poor fit far more likely. | Free sizing kit selectable at checkout and shipped before the ring, adding one to two weeks to the order. |
| Returns & Size Exchange | Not published on Amazfit's US product page; the store's standard terms apply and should be checked before ordering. | 14 days for returns and exchanges. |
| Measured vs Inferred | PPG optical sensor for heart rate and blood oxygen, plus a genuine EDA (electrodermal activity) sensor for stress — one of the few rings here where 'stress' has a dedicated sensor behind it rather than being inferred from HRV alone. Readiness and sleep scores are still derived. | Optical heart-rate sensor, skin-temperature sensor and accelerometer. Heart rate, SpO2, HRV, respiratory rate and skin temperature are tracked; stress is a derived score. Sleep-apnea monitoring, which the full Gen 2 has, is absent from this model. |
| FDA Clearance | None published. General wellness product; the EDA sensor is not a cleared medical measurement. | None published. General wellness product. |
| Water Rating | 10ATM | IP68 (100m/328ft) |
| Phone Support | iOS and Android through the Zepp app | iOS 17.0+ and Android 10.0+ |
| Charger & Data Export | Wireless charging dock, and Amazfit's own US page states the USB-C cable is not included in the box — you supply your own. Export: not published by the manufacturer. | Magnetic charging dock rather than the Gen 2's case — the biggest thing you give up alongside apnea monitoring, because there is no pocketable reserve of charges. Export: not published by the manufacturer. |
| Warranty | 12 months | 12 months |
| Colors | Titanium | Dune Gold, Galaxy Silver |
Category Scores
Subscription Freedom
The Amazfit Helio Ring (2024) and RingConn Gen 2 Air (2025) are level here, at 9.5/10 each. how much of the ring keeps working with no recurring payment — the category's defining trap is not what separates these two — look to the categories where the scores diverge.
Sleep Tracking
The RingConn Gen 2 Air (2025) leads clearly here, 7.8 against 7.0 — a 0.8-point margin on sleep staging depth, overnight accuracy and how usable the morning report is. If that is what you are buying for, the Amazfit Helio Ring (2024) does not close the gap elsewhere.
Health Sensing
The RingConn Gen 2 Air (2025) is marginally ahead, 6.8 to 6.5. A gap this small rarely decides a purchase on its own, though it counts if what the sensors genuinely measure — heart rate, SpO2, temperature, ECG — rather than infer is your priority.
Battery Life
The RingConn Gen 2 Air (2025) leads clearly here, 8.3 against 4.5 — a 3.8-point margin on real days between charges with continuous sensing on, plus what the charging case adds. If that is what you are buying for, the Amazfit Helio Ring (2024) does not close the gap elsewhere.
Sizing & Fit
The RingConn Gen 2 Air (2025) leads clearly here, 8.3 against 3.0 — a 5.3-point margin on how many sizes exist, how good the sizing kit is, and how forgiving the exchange policy is. If that is what you are buying for, the Amazfit Helio Ring (2024) does not close the gap elsewhere.
App & Data
The RingConn Gen 2 Air (2025) is marginally ahead, 7.3 to 7.0. A gap this small rarely decides a purchase on its own, though it counts if app stability, insight depth, platform parity and whether you can get your history out is your priority.
Durability
The RingConn Gen 2 Air (2025) is marginally ahead, 7.8 to 7.5. A gap this small rarely decides a purchase on its own, though it counts if finish scratch resistance, water rating in practice, and whether the finish is warrantied is your priority.
Value
The RingConn Gen 2 Air (2025) leads clearly here, 9.0 against 7.0 — a 2.0-point margin on what the ring delivers against its total cost of ownership, not just its sticker price. If that is what you are buying for, the Amazfit Helio Ring (2024) does not close the gap elsewhere.

Pros & Cons
Amazfit Helio Ring (2024)
Pros
- +$149.99 with no subscription — the cheapest ring here from a manufacturer with a real wearables business behind it
- +An actual EDA sensor for stress rather than an HRV-derived guess
- +10ATM water rating matches rings costing twice as much
- +Zepp Aura Premium is bundled, not upsold
Cons
- −Three sizes, full stop — 8, 10 and 12. This is the single biggest reason to buy something else
- −Four-day battery is the worst here by a wide margin; RingConn's cheapest ring does ten
- −Amazfit's own page says no USB-C cable is in the box
- −Data is most useful if you already own an Amazfit watch; standalone the Zepp app is thinner than Oura's
- −The Helio Ring 2 has been confirmed for the second half of 2026, so this is end-of-cycle hardware
RingConn Gen 2 Air (2025)
Pros
- +$199 all-in, and $199 is still the three-year cost — a base Oura Ring 5 is $608.97 over the same period
- +Ten-day battery in a 2mm, 2.5-4g band that does not look like a wearable
- +Same IP68 / 100m rating as RingConn's flagship
- +RingConn's Oura settlement means the US supply is licensed, not provisional
Cons
- −Sleep-apnea monitoring is removed — that is the specific feature the $269 Gen 2 keeps, and the reason for the price gap
- −Dock charger instead of a charging case, so no reserve charges when travelling
- −Only two finishes, both light-coloured, and no matte black
- −14-day return window in a category where the number one complaint is fit
- −No published data export
