Samsung’s smart ring is finally fully launched, and you can read our Samsung Galaxy Ring hands-on review for the full tour. But there’s one smaller detail that’s emerged now, aside from the price: the Galaxy Ring’s battery life varies depending on the size you opt for.
The Galaxy Ring sizing is based on standard US sizes, with nine different options ranging from US size 5 through size 13. However, Samsung says that the availability of Ring sizes and colors may vary by region.
How do you know what size to choose? You’ll be given the option to receive a free Sizing Kit (see further down this page) when you order, if you select the “I don’t know my size” option. Of course, these are just dummy Galaxy Rings and are there to help you pick the right one – Samsung says you should wear these sizing charts for 24 hours to see which one is the right fit.
As rumored, the Galaxy Ring’s weight and battery life will vary depending on the size you opt for. The two largest sizes (12 and 13) have a different battery cell, meaning they can last up to seven days on a single charge. All of the sizes below that have a battery life rated at “up to six days.”
| Row 0 – Cell 0 | Weight | Battery life |
| Size 5 | 2.3 grams | Up to six days |
| Size 6 | 2.4 grams | Up to six days |
| Size 7 | 2.4 grams | Up to six days |
| Size 8 | 2.6 grams | Up to six days |
| Size 9 | 2.7 grams | Up to six days |
| Size 10 | 2.8 grams | Up to six days |
| Size 11 | 3.0 grams | Up to six days |
| Size 12 | 3.0 grams | Up to seven days |
| Size 13 | 3.0 grams | Up to seven days |
Interestingly, the size of the Galaxy Ring charging case will also vary slightly depending on the size of the ring you opt for. You get one charging case and a USB cable with the smart ring, with a wireless charger sold separately.
Choose carefully
While the Samsung Galaxy Ring comes in standard US sizes, Samsung warns that your size may vary from traditional, non-smart rings. This is due to the sensors inside.
The ring can be worn on any finger, but the sensors should be facing upwards, with the indicator on the palm side. The reason Samsung recommends wearing the dummy ring for 24 hours is because the size of the finger can vary depending on the time of day, so you’ll want to make sure it’s not too tight at night, for example.
Once you’ve chosen your size, you can choose from three Galaxy Ring colours; it comes in black, titanium gold and titanium silver. They’re all made from scratch-resistant titanium and the design cleverly features raised edges so it won’t get scratched easily.
Of course, the price doesn’t depend on which size ring you choose either: it costs $399 / £399 (or around AU$750, Australian pricing is yet to be confirmed), which is a little more than the Oura Ring, though you don’t need a data plan for Samsung’s ring.
We’re looking forward to trying out the Samsung Smart Ring for a while, but until then, read our hands-on Samsung Galaxy Ring review.
