Battery Life & Charging Time, Explained



  • The battery life of the Galaxy Watch 6 series is slightly lower than the previous generation, with 30 hours of usage with Always On display and 40 hours without it.
  • The Watch 6 and Watch 6 Classic battery can charge up to 45 percent in 30 minutes with a 10W charger. An eight-minute charge results in eight hours of usage.
  • The watches also support Wireless PowerShare for charging through compatible Galaxy smartphones.



Samsung‘s Galaxy Watch 6 and Watch 6 Classic bring several upgrades over their predecessors, but does this include improvements to the battery life? The Galaxy Watch 6 series doesn’t include a Pro model this time around. Both the Watch 6 and Watch 6 Classic are more similar than different, with the main distinguishing feature being the Watch 6 Classic’s larger case size and rotating bezel.

Both the Watch 6 and Watch 6 Classic feature an Always On display, and despite the usefulness of this feature, it can have a big impact on battery life. As per Samsung, users can expect 30 hours of usage with the Always On display turned on, and 40 hours with the Always On display turned off. Surprisingly, these numbers are lower than the Galaxy Watch 5’s claimed 50 hours of usage. It’s possible that Samsung has used more conservative estimates with the Watch 6, given that the Galaxy Watch 5 doesn’t last close to 50 hours in real life usage.
