Side-by-Side Comparison
| Spec | Amazfit Helio Ring (2024) | RingConn Gen 2 (2024) |
|---|---|---|
| Price | $149.99 | $269.00 |
| Release Year | 2024 | 2024 |
| Battery Life (claimed) (days) | 4 | 12✓ |
| Battery, In Practice | Amazfit publishes 'up to 4 days' — the shortest claim in this comparison, and it is the headline figure, so continuous SpO2 and temperature sensing pull it down from there. Wireless charging takes about 1 hour 40 minutes. | RingConn publishes 10-12 days for the ring and 150 days including the case. There is no vibration motor to switch off, so the figure is less conditional than the Gen 3's. Ring charges in about 90 minutes. |
| Subscription | None. Amazfit states no subscriptions are required, and Zepp Aura Premium (sleep sounds, detailed sleep reports, AI chat) is included free rather than sold separately. | None. Sleep-apnea monitoring, continuous SpO2, cycle tracking and every other metric are included with the hardware. |
| 3-Year Cost of Ownership ($) | 149.99✓ | 269 |
| 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, shipped ahead of the ring; the kit round trip adds one to two weeks before the ring is dispatched. |
| 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, in line with RingConn's other rings. |
| 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 and temperature are tracked continuously rather than spot-sampled. The sleep-apnea figure RingConn quotes (90.7% accuracy) is a risk indicator derived from those signals, not a clinical sleep study. |
| FDA Clearance | None published. General wellness product; the EDA sensor is not a cleared medical measurement. | None published. Sleep-apnea monitoring is marketed as a wellness risk indicator; it is not an FDA-cleared apnea diagnostic. |
| 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 case included, good for about 150 days of ring charges. Export: not published by the manufacturer. |
| Warranty | 12 months | 12 months |
| Colors | Titanium | Royal Gold, Future Silver, Matte Black, Rose Gold ($359) |
Category Scores
Subscription Freedom
The Amazfit Helio Ring (2024) and RingConn Gen 2 (2024) 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 (2024) leads clearly here, 8.3 against 7.0 — a 1.3-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 (2024) leads clearly here, 7.8 against 6.5 — a 1.3-point margin on what the sensors genuinely measure — heart rate, SpO2, temperature, ECG — rather than infer. If that is what you are buying for, the Amazfit Helio Ring (2024) does not close the gap elsewhere.
Battery Life
The RingConn Gen 2 (2024) leads clearly here, 8.7 against 4.5 — a 4.2-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 (2024) leads clearly here, 8.5 against 3.0 — a 5.5-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 (2024) 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 (2024) leads clearly here, 8.0 against 7.5 — a 0.5-point margin on finish scratch resistance, water rating in practice, and whether the finish is warrantied. If that is what you are buying for, the Amazfit Helio Ring (2024) does not close the gap elsewhere.
Value
The RingConn Gen 2 (2024) leads clearly here, 8.7 against 7.0 — a 1.7-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 (2024)
Pros
- +Sleep-apnea monitoring included with no subscription — the Gen 2 Air drops this feature entirely
- +$269 on sale from $299, and three-year cost is that same $269
- +2mm thick and 2-3g, thinner and lighter than any Oura
- +150-day charging case means one wall charge a season
Cons
- −The apnea figure is RingConn's own 90.7% accuracy claim, not an FDA-cleared diagnostic — it flags risk, it does not diagnose
- −Rose Gold is $359, $90 above the sale price of the other finishes
- −Bluetooth 4.0-class radio and a 2024 sensor stack; the Gen 3 adds vibration alerts and vascular trending
- −14-day return window, and RingConn sizes do not map to standard US ring sizes
- −No published data-export route, so your history lives in RingConn's app
