Samsung Galaxy Watch 4 battery information detailed in new leak

TheElec has provided more details about the Galaxy Watch 4 series, Samsung's upcoming flagship smartwatches for 2021. According to TheElec, Samsung will source batteries from Amperex Technology Limited (ATL) and its subsidiary Samsung SDI. Samsung and ATL have had a checkered relationship, with the former blacklisting the latter after it supplied batteries for the infamous Galaxy Note 7. Samsung uses ATL batteries in the Galaxy S21 series though, so their relationship must have improved since 2016.

Apparently, ATL will supply batteries for the Galaxy Watch 4's 41 mm version, with Samsung holding its SDI subsidiary responsible for the 45 mm version. TheElec asserts that the smaller model will have a 240 mAh battery and the larger one a 350 mAh battery, although it may only be repeating what a 3C listing showed last month.

While these battery capacities are similar to the ones in the Galaxy Watch 3 series, the rumoured switch from Tizen OS to Wear OS means that we cannot estimate the Galaxy Watch 4's battery life. Wear OS smartwatches tend to have worse battery life than Tizen OS equivalents, so it will be interesting to see what optimisations Samsung has made on the Galaxy Watch 4 series. Samsung is expected to launch the Galaxy Watch 4 and Watch Active 4 in late Q2 2021.
