Checking your Apple Watch's battery health is easier than you think

The Apple Watch Ultra 4 boasts impressive battery life, lasting up to 84 hours in low power mode. However, like all lithium-ion batteries, its capacity diminishes over time, resulting in reduced usage time between charges and overall performance degradation. Apple's newer models, including Series 5, SE, and Ultra, come equipped with software to mitigate poor performance risks.

To maintain optimal battery health, Apple Watch owners should regularly check battery status. This can be done in the Settings > Battery > Battery Health menu, where users can enable optimized battery charging and view maximum battery capacity. If the battery's maximum capacity falls below 80%, a visit to the Genius Bar may be necessary.

Fortunately, users receive an alert when the battery needs servicing. The optimization feature, available on Series 6, SE, and Ultra models, charges based on typical usage patterns to prolong battery life. It also limits charging above 80% to preserve battery health. Beyond software solutions, users can extend battery life by enabling Low Power Mode to turn off certain features that consume power in the background.

During workouts, disabling the heart rate sensor can also help conserve battery. Additionally, disabling features like Wake on Wrist Raise can further extend battery life by preventing unnecessary screen activation.
