Samsung has continued to improve its smartwatches year after year. Two years ago, the company switched from Tizen to Wear OS 3. However, with the Galaxy Watch 4, the battery life left a little to be desired. Next year, the company improved the battery life with the Galaxy Watch 5, and it will continue doing that next year.
The Galaxy Watch 6's battery for the 40mm version has been spotted (by GalaxyClub) on Safety Korea's website. It carries model number EB-BR935ABY and has an advertised capacity of 300mAh. In comparison, the 40mm version of the Galaxy Watch 5 has a 284mAh battery. That's a 5% bigger capacity, but it's an increase in capacity nonetheless. If Samsung brings a more power-efficient display and chipset, it could still offer improved battery life.
The Galaxy Watch 5's 40mm version has model number SM-R93x, while the 44mm version of the smartwatch has model number SM-R94x. There will most probably also be a Pro version of the Galaxy Watch 6 with an even bigger battery capacity, leading to longer battery life.
While not much is known about the Galaxy Watch 6, it is rumored that Samsung will go back to the curved screen design that we saw with the Galaxy Watch Active 2. It could use a display from CSOT. The smartwatch could also bring a newer version of One UI for Watch, improved activity and health tracking, and longer battery life.
