Although the Samsung Galaxy Ring was first unveiled at MWC 2024, there is still much we don't know about this giant tech company's highly anticipated smart ring, including how long it will last on a charge. Samsung has now confirmed that the Galaxy Ring will last 5-9 days on a single charge, which would be a battery life that would surpass that of its main competitor, the Oura Ring.

As first reported by 9to5Google, Dr. Hon Pak, Samsung's vice president of digital health, said as much in a recent press briefing covered by Financial News. Samsung's mobile chief TM Roh also estimated battery life at 5 to 9 days in a February TechM report found by Android Authority. Roh also confirmed that the ring will not support phone calls, unlike Samsung's other wearables like the Galaxy Watch 6.

The Galaxy Ring has no screen and can last up to 9 days on a single charge, Financial News reported. Of course, whether the battery life actually lasts that long is unknown and may vary depending on usage. [For example, the Oura Ring, one of the best fitness trackers on the market today, claims to last up to seven days on a single charge. However, in our tests, the Oura Ring Generation 3 required recharging on average about every five days; our colleague Kate, who wore the Oura Ring Gen 3 for a year, had the same experience, but after Oura added the blood oxygen sensing feature, enabling continuous SpO2 monitoring she found that the battery life dropped to 3 days.

The same may be true for the Galaxy Ring; it remains unclear how the Galaxy Ring will use sensors to track activity, sleep, and other health metrics. Some wearables use periodic readings to save battery life, while others rely on continuous tracking or offer users the option to toggle between the two. if the Galaxy Ring is like the Oura Ring, continuous tracking enabled means sacrificing battery life. The size of the ring (Samsung offers the Galaxy Ring in nine different sizes) may also affect the charging interval.

However, if this 9-day estimate is true, the Galaxy Ring would have a significant advantage over other smart rings. If you're sick of charging your smartwatch every day or running out of battery on your Oura Ring, this would definitely be one wearable to keep an eye on. Dr. Hon Pak, Samsung's vice president, previously told The Elec that the Galaxy Ring will be available later this year.
