According to the FCC listing details spotted by Xpertpick first, the Galaxy Watch 8 appears with model numbers SM-L335U and SM-L335F, confirming these are LTE variants of the device.

The certification reveals the watch will support Wi-Fi, Bluetooth 5.3 LE, GNSS, NFC, Wi-Fi Hotspot for sharing cellular data and Wi-Fi Direct for quick data transfers between devices.

As for charging, the label shows 10W charging support (5V/2A) and it will work with a wireless charger (model number EP-OL300). The battery for the Watch 8 was previously seen on Safety Korea with the model number EB-BL330ABY. It also appeared on TÜV Rheinland confirming a 435mAh capacity, which is just 10mAh more than the Galaxy Watch 7’s 425mAh battery.

Moreover, recent Bluetooth SIG and Safety Korea listings suggest that Samsung might bring back the Classic model, which was last seen with the Galaxy Watch 6 Classic in 2023.

One UI 8 Watch Update – What To Expect?

In addition to hardware leaks, a look at Samsung’s upcoming One UI 8 Watch software has also surfaced online. Leaked by @DevOfIpos on X (formerly Twitter), the new update includes new colourful icons across Samsung apps matching the One UI 7 aesthetic.

It also suggests Google Gemini replacing Google Assistant, confirming earlier reports that Gemini will come pre-installed on Wear OS 6.

Android Authority accessed the update files and found hints of “Gemini Actions.” These can help users move calendar events, summarise emails and more. All of which essentially function like an upgraded Assistant.

Another exciting feature is the “Antioxidant Index”, which Samsung teased earlier this year. It uses the health sensor on the Galaxy Watch to non-invasively measure beta-carotene levels, helping users tailor their nutrition. Samsung is clear that this is not meant to diagnose medical conditions.

<string name=”antioxidant_guide_text_one”>To measure, press the pad of your thumb firmly on the center of the sensor on the back of your watch.</string>

<string name=”antioxidant_guide_text_two”>You can check measurement progress on your phone.</string>

<string name=”antioxidant_help_measure_guide”>For more accurate results, measure with your thumb, not your wrist, and space out measurements by at least 10 seconds.</string>

<string name=”antioxidant_help_description_text”>”Keep in mind that antioxidant index measurement is for fitness and wellness only, not for the diagnosis or treatment of any medical condition. If you’re concerned about your antioxidant level, be sure to see a medical professional.”</string>
