The Ultrahuman Ring Pro builds on the Ultrahuman Ring Air's features with several key improvements, including an impressive battery life of up to 15 days, which is more than twice as long as the Air.
The Xiaomi Watch 5 has a 930mAh power pack. That's massive. Compare that with the OnePlus Watch 3's perceptively huge 648mAh battery - the Xiaomi Watch 5 has a 43% bigger battery! Xiaomi recons you can get a total of 6 days of endurance - unheard of for a Wear OS watch!
Wellune looks like a small, sculptural lamp. A slender white stem curves upward from a flat circular base, blooming into a soft, rounded head that sits somewhere between a sprouting bud and a modernist desk light. The head detaches magnetically, which is a lovely detail because it turns setup into something almost playful. You hold this smooth, egg-like dome in your hand, place it on the stem, and it clicks into position with a satisfying connection.
The smartwatch got smaller. Then the smart ring arrived. Now Rogbid has released something that splits the difference and costs less than a nice dinner: the Fusion, a hybrid device that looks like someone shrunk a fitness tracker and stuck it on a ring band. For fifty dollars, you get a legitimate OLED display, actual health sensors, and the ability to wear your technology on whichever body part feels right that day.
If there's one thing that stops people using their smart rings over the long term, it's the battery life. After all, they're so unobtrusive, it's easy to forget to drop it on the charging plate every few days. It doesn't take long for your pricey gadget to become little more than a very expensive piece of jewelry.
