Signs Your Battery Needs Replacing
Lithium-ion batteries naturally lose capacity over time. Common signs include your watch not lasting through the day like it used to, the charge percentage dropping unusually fast during workouts or sleep tracking, the watch shutting off unexpectedly even when the display shows remaining charge, or the watch taking noticeably longer to reach a full charge. A battery that feels warm during normal use or a watch body that appears slightly swollen or lifted at the back cover are also signs the battery should be replaced soon.
