Jawbone today launched a free firmware update that gives its UP24 activity tracker a battery boost.
Its already week-long lifespan has been kicked into overdrive, now promising to run on one charge for a full 14 days.
"Staying on the wrist 24/7 is an important part of the UP experience, as it allows our community to get the most accurate view of their day," Hari Chakravarthula, executive director of Jawbone's systems engineering, wrote in a blog post. "With today's update, you won't miss a single step (or moment's sleep)."
The tracker received an "excellent" 4-out-of-five stars in PCMag's review, which tipped a 5-7 day battery life, depending on use. Setting a bunch of vibration alarms, for example, will tax the battery more often.
This week's update, however, means you can set a few more alarms and not worry about straining your device.
The UP24 tracker launched in November, alongside a revamped UP iOS mobile app, which provides continuous feedback and real-time notifications.
Designed with the same smooth, hypoallergenic, medical-grade rubber exterior as the original UP, Jawbone's next-gen wearable is available for $149.99 in three sizes and six colors: red, navy blue, lemon line, onyx (black), persimmon (orange), and pink coral.
The hardware maker, meanwhile, also announced plans to open its software to other device makers, including Apple, FitBit, and Google. The move—much like Tesla Motors handing out its patents—is aimed at accelerating the activity wristband market.
According to a report from Reuters, Jawbone will also collect data from Apple's anticipated iWatch. The process would, for example, allow users to take off their UP tracker for the night, and instead pull sleep data from an iPhone or Android handset.
This doesn't mean the end for Jawbone's hardware, though. Quite the opposite: The company hinted to Reuters about sensor advancements in the coming months.
