Apple Watch Tips Stretch Battery to 43 Hours With 5 Power-Saving Tweaks
1 articles · Updated · PCMag · Jun 11
Summary
43 hours of battery life was achieved in testing on the Apple Watch Series 11, versus Apple’s typical 24-hour estimate, prompting five steps to extend runtime further.
Low Power Mode is the main battery-saving tool, cutting features such as Always On display, background heart and blood-oxygen measurements, some workout reminders, and reducing background refresh activity.
Two display changes can also trim power use: turning off Always On display and disabling Wake on Wrist Raise, while shortening tap-to-wake time to 15 seconds instead of 70.
Charging and connectivity settings matter too: temporarily disabling Optimized Battery Charging or charge limits can lengthen time between charges, and Airplane Mode—or just turning off Wi-Fi—can preserve power when connectivity is unnecessary.
The advice is aimed at heavier-use days such as sleep tracking or long travel, when an Apple Watch may otherwise run low before the end of the day.
