No. 1 has released a new smartwatch which has, according to the manufacturer, a standby time of 5 days. This goal can be achieved by the use of the 500 mAh battery on board. The 5 days achievement is more or less the double than the usual time of any comparable Android smartwatch. Other features are their second generation of a dynamic heart rate tracker and a better user experience.
Unfortunately no further specifications have been shared, so keep an eye on the official website of No.1.
