Samsung Galaxy Watch battery drain spikes after July update

Owners of Samsung Galaxy Watch models 6, 7 and 8 report a sudden loss of battery life shortly after installing the July security update. Users describe the charge dropping from around 75 % to single‑digit levels within a few hours, with some watches falling from 40 % to 10 % in under an hour. The rapid depletion is attributed to a software issue rather than a defective battery, as similar problems previously appeared with older Watch 7 models and were later fixed by Samsung through a firmware patch. Affected users have tried restarting the devices, clearing the system cache, and even performing factory resets, but results vary and no universal solution has been found. Samsung has not issued an official comment on the latest complaints, leaving the problem unresolved for many users.
