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. It’s one of many maladies Ultrahuman is looking to address with the advent of its new Pro, a smart ring boasting up to 15 days of battery life. It even ships with a fancy battery case, which itself includes enough power to last it 45 days, making it easier to keep re-charged on the go.
