Samsung is launching its first-ever smart ring today, and you'll never guess its name. I'm kidding, but did you know that, depending on whichGalaxy Ring you buy, the battery size will be different?

To be clear, this isn't anything new. The larger the ring size, the larger the battery capacity that can fit within the circular frame. If you are buying the ring in sizes 5 to 11, the battery capacity will be 18 mAh. If you have larger fingers, specifically sizes 12 and 13, the battery capacity will be 23.5 mAh.

The popularOura Ring does something similar, with its smaller sizes (US 6) having a 15 mAh capacity, while the larger sizes (US 13) have a 22 mAh capacity.

Of course, not everyone's fingers will miraculously fit the larger sizes, and the battery size of the ring definitely shouldn't be the main reason to buy one. If anything, Samsung has come up with several health and fitness benefits of owning its latest smart ring, and they're all just as nimble and burdenless to wear.

In fact, Samsung tells me that no matter which size your finger ultimately fits best, you can expect a good six days of battery life before needing to top it all up again, which is still better than your typical smartwatch's endurance.

Due to Samsung's (and the industry's) made-to-order approach to smart rings, the smallest and largest sizes may also have a longer turnaround time, so if you want your Galaxy Ring as soon as possible, it may not be in your best interest to get one of the extreme sizes.
