Ultrahuman’s Ring Pro Pushes Smart Ring Battery Life to 15 Days

Ultrahuman is taking direct aim at one of the biggest pain points in smart rings; short battery life. The company’s new Ring Pro is designed to run for up to 15 days on a single charge and ships with a battery case that can keep it topped up for a claimed 45 days before the case itself needs power.

Smart rings are easy to wear and just as easy to forget to charge. Once their batteries die, many end up as expensive jewellery rather than everyday health trackers. Ultrahuman is positioning the Ring Pro as a fix for that problem, combining longer battery life with a redesigned hardware platform and a more visible, feature-rich charging dock.

According to Ultrahuman, the Ring Pro has been rebuilt from the ground up rather than simply upgraded. Company representative Bhuvan Srinivasan said the previous hardware generation had been pushed to its limits, particularly in how much data it could process. In response, the Ring Pro now includes a dual-core processor with on-device machine learning, allowing it to analyse more of the biometric data it collects directly on the ring.

The internal memory has also been expanded. Ultrahuman says the Ring Pro can store up to 250 days of data before it needs to sync with a smartphone, reducing reliance on constant connectivity for historical metrics.

Durability has been improved as well, and the physical design has been adjusted so the ring is easier to cut off in the unlikely event a wearer’s finger swells or if the battery itself swells and the ring needs to be removed quickly.

Alongside the ring, Ultrahuman is introducing a Pro Charger that doubles as a battery case. The case holds enough charge to power the ring for around 45 days, making it suitable for travel or simply reducing how often users have to think about cables and sockets.

Unlike the small, box-style chargers used by some rivals, Ultrahuman has built the Pro Charger to sit in plain sight on a nightstand or desk. It incorporates:

• An integrated battery for extended charging on the go
• An LED charge indicator
• A speaker and haptics
• Diagnostic capabilities to detect and address firmware issues

That last feature is intended to reduce the risk of firmware problems bricking the device, by giving the charger a more active role in managing and recovering the ring’s software.

In parallel with the Ring Pro, Ultrahuman is introducing Jade, described as a “real time biointelligence AI.” The system is designed to sit across the company’s ecosystem and act on health and environmental data pulled from multiple devices.

Ultrahuman says Jade will be able to surface real-time, actionable insights for users. The company claims it can trigger features such as breathwork sessions or atrial fibrillation (Afib) detection based on what it sees in the data.

Over time, Ultrahuman expects Jade to gain additional capabilities. The company gives examples that include:

• Ordering items (such as food)
• Adjusting room temperature
• Flagging potential health concerns based on trends

Jade is meant to draw from several Ultrahuman products and data sources, including:

• The Ring Pro smart ring
• The Ultrahuman M1 continuous glucose monitor
• Environmental data from Ultrahuman Home

The vision is a system that continuously monitors a user’s wellbeing and surroundings, then acts or alerts based on that information, rather than simply logging metrics for later review in an app.

Independent testing of the Ring Pro’s battery life, durability, data accuracy and Jade’s practical usefulness will determine how well this approach works in everyday use. For now, Ultrahuman is opening pre-orders for the Ring Pro outside the United States at a price of $479, with shipments scheduled to begin in March, according to the company. Existing Ultrahuman ring owners are being offered a trade-in option to reduce the upgrade cost.
