This information comes from various sources, including Korean news outlets and Samsung executives such as Hong Park and Roh Tae Moon. However, skepticism is advised. Remember the Oura Ring? It promises 7 days, but in real conditions it usually works for 3-5 days with continuous SpO2 monitoring.
The Galaxy Ring’s battery life will likely depend on many factors. That’s why continuous monitoring usually drains the battery faster than periodic readings. It is also unknown to what extent Galaxy Ring’s continuous tracking features will be used. At the same time, there is not much space in the rings for batteries with a capacity that can affect battery life, as in small smart watches.
Despite these considerations, the prospect of up to 9 days of battery life seems attractive, especially when compared to charging a smartwatch every day.
