"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."
"Ultrahuman Ring Pro hasn't just got a far bigger battery, it's been re-engineered from the ground up. The company's Bhuvan Srinivasan explained the older hardware had been pushed to its limit, especially in terms of the data it could process. Consequently, the Pro is equipped with a dual core processor with on-device machine learning to better crunch the numbers your body is throwing out."
"I'll admit, having seen a prototype Pro Charger in person back in January, that it's the prettiest way to re-juice a smart ring I've ever seen. Whereas Samsung and Oura have both opted for discreet, ring box-style hardware, Ultrahuman made something designed to sit on your nightstand. It's not taking up space just for show, either, since it includes the aforementioned battery, LED charge indicator, speaker and haptics."
Ultrahuman Ring Pro represents a significant redesign of the smart ring, addressing the primary issue of battery life that causes users to abandon wearables. The new device offers up to 15 days of battery life, with an accompanying charging case that extends usage to 45 days total. The ring has been completely re-engineered with a dual-core processor and on-device machine learning capabilities to improve data processing. Memory capacity has increased to store 250 days of data before syncing with a smartphone. The charging case itself is a premium accessory featuring an LED indicator, speaker, haptics, and firmware diagnostic capabilities. Durability improvements include easier disassembly in case of swelling.
