RingConn Gen 2 vs Gen 2 Air — Which Budget Ring Wins in 2025?
RingConn shook up the smart-ring world with its free-for-life analytics and marathon battery life. Now the company offers two second-generation models: the flagship Gen 2 and the lighter, cheaper Gen 2 Air. Below we pit them head-to-head on every spec that matters—so you can pick the right ring without guesswork.
1. Quick-Spec Snapshot
| Ring | Weight | Battery Life | Waterproof Depth | Charging | Price* |
|---|---|---|---|---|---|
| RingConn Gen 2 | 2 – 3 g | 10 – 12 days (+ case 150 d) | 50 m / IP68 (now rated 100 m in latest batch) | Mag-dock + included pocket case (≈15 refills) | $299 |
| RingConn Gen 2 Air | 2.5 – 4 g | 8 – 10 days | 100 m / IP68 (10 ATM) | USB-C pogo-pin dock (no case) | $199 |
*MSRP in USD. No subscription for either model.
2. Design & Comfort
The flagship Gen 2 keeps an aerospace-grade titanium-alloy frame that’s just 2 mm thick at the narrowest point, creating a premium matte finish that resists scratches. The new Gen 2 Air swaps to a stainless-steel/epoxy hybrid that’s easier (and cheaper) to machine. Despite a hair wider 6.8 mm profile, it remains feather-light at a claimed 2.5 g for a size 7 ring.
3. Battery & Charging
RingConn still owns the endurance crown: Gen 2 lasts 10–12 days per charge and ships with a pocket-size charging case that can top the ring up about 15 times, stretching total runtime to roughly 150 days between USB-C plugs.
The Air model drops the case yet still manages a respectable 8–10 days on its slimmer cell, recharging in an hour on a compact pogo-pin cradle. If you travel without outlets, the flagship clearly wins; if you plug in weekly anyway, Air may suffice.
4. Sensors & Metrics
Under the hood, both rings share the exact five-sensor array—dual-LED PPG for HR/HRV, SpO₂, an NTC skin-temperature duo and a 3-axis accelerometer for movement detection. Therefore they deliver the same Sleep Score, Readiness Score and automatic Sleep-Apnoea Index that RingConn’s AI engine introduced with Gen 2 software updates.
5. Waterproof & Durability
Both rings boast an IP68 rating, but RingConn upgraded Gen 2 Air to a full 10 ATM / 100 m depth certification for confident scuba dives. Early Gen 2 batches were advertised at 5 ATM (50 m) yet the latest production run lists the same 100 m spec, so double-check your retailer’s listing.
6. Price & Value
At $299, Gen 2 costs exactly $100 more than the Air but bundles the handy charging case and premium titanium build. If you crave maximum runtime or value a jewelry-grade finish, it’s worth the extra cash. Otherwise, the $199 Gen 2 Air delivers the same health data at the lowest entry price of any major-brand ring today.
7. Verdict: Which Should You Buy?
- Best for Frequent Travelers & Divers: RingConn Gen 2 — unrivalled battery endurance plus charging case.
- Best Ultra-Light Budget Pick: RingConn Gen 2 Air — same metrics, half the price.
No matter which model you choose, you’ll enjoy lifetime-free analytics, raw CSV exports and one of the longest batteries in the category. Compare both against every other ring in our interactive comparison table to see how they stack up on niche features like EDA and ECG.
8. FAQ
Does the Gen 2 Air lose any health metrics?
No—hardware and firmware are identical, so sleep-apnoea detection, HRV and readiness scoring work the same across both rings.
Can I buy the charging case separately later?
RingConn sells the case as a standalone accessory (~$39) but stock is limited; buy the flagship bundle if you know you’ll want it.
Will RingConn ever charge a subscription?
The company publicly commits to “free data for life,” but premium AI reports could arrive as optional add-ons—watch future app updates.
The Bottom Line
If you want the longest possible battery and truly off-grid charging, opt for the titanium-clad RingConn Gen 2.
If your priority is saving $100 without sacrificing metrics, grab the feather-weight Gen 2 Air and never look back.
