‘Various sources’ say Galaxy Watch 4 could have 7-day battery life

June 05, 2025

One of the biggest complaints when it comes toGoogle’s current version of Wear OSis battery life. Most Wear OS watches can eke out a day of life before they need to be charged. If you use it for a lot of workouts, music streaming, or sleep tracking, it’s likely you won’t even get that full day.

One of our big hopes is thatSamsung’s and Google’s Wear OS 3.0will solve this problem. According to a new rumor roundup fromWinFuture, it’s possible our wish may come true. According to “various sources” speaking withWinFuture, the Samsung Galaxy Watch 4 could have up to seven days of battery life.

Now, that’s a lot of battery life for pretty much any wearable. That would bestall Wear OS watches, most fitness-based watches such as theFitbit Sense, and even theApple Watch. That’s why we’re pretty skeptical of this claim.

Although it certainly is likely Wear OS 3.0 watches like the Samsung Galaxy Watch 4 will have better battery life than current models, seven days is a big jump. It’s possible that this number reflects the use of some sort of battery-saver mode, rather than the basic out-of-the-box mode. For example,Mobvoi’s line of TicWatchescome with an Essential Mode that sips on the battery. If you only used that, you could get weeks of battery life. However, saying the watch gets weeks of battery is not totally true, since you’d need to have nearly all other features turned off.

Still, we can’t rule out the possibility that this Samsung Galaxy Watch 4 rumor is true and applies to the default configuration. If that’s how things pan out, Wear OS 3.0 watches could be game-changers for the entire industry.
