A free scan shows the junk files, broken settings and background clutter dragging Windows down - then fixes them in one click.Free scan · Windows 10 & 11A May 28, 2024 FCC filing for Samsung’s first-generation Galaxy Ring documented nine size-specific model variants, three reported battery capacities, Bluetooth Low Energy connectivity and a charging cradle. It made the hardware lineup more concrete, but it was not a complete retail announcement: details such as runtime, price, package contents and cradle compatibility were not established by the filing.
What the FCC filing showed
The filing, under FCC ID A3LSMQ503, identifies SM-Q503 as the basic model and lists nine Galaxy Ring variants. The FCC exhibit record is available in the FCC filing; the model and hardware details were reported by Droid Life on May 28, 2024.
- SM-Q500
- SM-Q501
- SM-Q502
- SM-Q503
- SM-Q505
- SM-Q506
- SM-Q507
- SM-Q508
- SM-Q509
SM-Q504 is absent from the listed sequence, but the filing is reported to contain nine variants, not eight. Images associate the models with different ring sizes and show the ring and its charging cradle. The variants indicate size options, not evidence of nine feature tiers.
How many sizes were there?
The filing added model-number and image evidence for nine sizes. It did not mark Samsung’s first public indication of that count: Samsung had already discussed a nine-size range in pre-release coverage, alongside multiple finishes. That earlier preview also showed a slightly concave exterior and sensors beneath a darker inner section (Droid Life’s Galaxy Ring preview).

The FCC evidence does not establish a mapping from each model number to a conventional U.S. ring size. Use Samsung’s official sizing process rather than choosing solely by the size of a regular ring. Smart-ring fit matters for comfort and sensor contact; knuckle shape, finger choice, temperature and swelling can affect how a ring feels over a full day or overnight. Samsung’s product page is the official starting point for its sizing information.
Reported battery capacity varies by size
The May 2024 filing coverage reported three capacity tiers. It did not provide a complete size-by-size capacity mapping in the cited reporting.
| Size grouping | Reported capacity |
|---|---|
| Smallest size | 17 mAh |
| Mid-range sizes | 18.5 mAh |
| Largest size | 22.5 mAh |
These are battery-capacity figures reported from the filing, not battery-life ratings. A larger battery may offer more capacity, but the filing does not establish how many days any size lasts. Runtime also depends on factors such as sensor use, syncing, firmware and temperature; there is no sound way to turn these mAh figures into an exact runtime without a separate test or official runtime claim.

If you fall between sizes, do not choose a looser or uncomfortable fit just to pursue the larger reported capacity. The filing does not show that the capacity difference translates into a particular real-world runtime advantage.

What the charging cradle does—and does not—tell us
The FCC material showed a dedicated charging cradle, including labeling on its underside; the accessory was also referenced in user-manual material. The report noted separate cradle model numbers, but did not establish whether cradle dimensions or compatibility vary by ring size.
A purpose-made holder can position a small ring for charging, but the filing evidence cited here does not establish the cradle’s electrical specifications or the full retail charging arrangement. It does not confirm whether a cradle is bundled with every ring, whether one cradle fits every size, or whether it has an internal battery or serves as a travel case. Those are separate product and package details, not conclusions to draw from its appearance in a regulatory filing.

Bluetooth LE is the radio clue, not a full compatibility list
The filing coverage reported Bluetooth Low Energy (BLE) connectivity. That low-power radio is consistent with a wearable that sends data to a phone. It does not mean the ring has cellular service, and it does not establish Wi-Fi, NFC, GPS or standalone operation. BLE alone also cannot answer whether the ring stores data when it is away from a phone and syncs later.
Samsung had previously positioned the ring around Samsung Health and wellness features, including planned My Vitality Score and Booster Card features, as described in its pre-release coverage and linked Samsung newsroom. The FCC listing does not determine which phones support each feature, whether a Samsung account is required, or whether any feature depends on a Galaxy Watch.
What the filing did not confirm
An FCC filing is useful evidence about submitted hardware and radio behavior; it is not a complete specification sheet or retail announcement. The cited filing coverage did not establish:

Those details require official product, support and sales information; they cannot be settled by the model numbers or radio listing alone.
What prospective buyers should take from it
- For sizing: wait for Samsung’s sizing guidance and prioritize a secure, comfortable fit over a conventional ring-size label.
- For battery expectations: treat 17, 18.5 and 22.5 mAh as reported capacity tiers, not a promise of days between charges.
- For charging: the filing shows a cradle, but not whether it is included or shared across sizes.
- For phone support and services: verify compatibility, feature requirements and any service terms against Samsung’s current regional documentation.
The listing is a May 2024 hardware snapshot, not a new 2026 leak. Its clearest contribution was documentation of nine size variants, three battery-capacity tiers, BLE and a charging cradle; it leaves the key retail and day-to-day questions to product information beyond the filing.
