GoKawiilHow to check Apple Watch battery health, explained
Apple Watch batteries, like other lithium-ion batteries, degrade over time, resulting in shorter runtime and reduced capacity. Apple includes software on Series 5, SE and Ultra models designed to limit performance problems as batteries age, but users are advised to periodically check battery health themselves to decide whether to replace the battery or the device.
GoKawiil's interpretation of the reporting above, not reported fact.
As wearables pack in bigger batteries and longer claimed runtimes, such as the new Apple Watch Ultra's 50-hour rating, understanding real-world degradation becomes more relevant for owners planning long-term use. Easy access to battery health data could help consumers make informed decisions about repair versus upgrade, potentially affecting Apple's replacement and trade-in business.
- Lithium-ion batteries in Apple Watches degrade with age, reducing battery life and performance.
- Apple includes software safeguards starting with Series 5, SE and Ultra models to mitigate this.
- Users can check battery health directly to decide between battery replacement or a new device.
