Hello, TurtleX. Thank you very much for sharing your experience with us. We're sorry to hear you aren’t satisfied with your purchase. We completely understand how frustrating it is when a battery doesn’t last as long as expected, and the inconvenience that having a limited-service coverage can cause in your daily routine. To help improve your Apple Watch's battery life, please try these simple steps: ✅Check for updates: Always ensure your Apple Watch is using the latest version of watchOS. ✅Enable Low Power Mode. ✅Manage Background App Refresh: Go to Settings > General > Background App Refresh and turn it off for apps you don’t need constant updates from. ✅Reduce Screen Brightness: Lowering the brightness by even one bar can help. ✅Turn off unused features: Features like "Always On" display, continuous heart rate tracking, or cellular connectivity consume more power. Disabling these can make a noticeable difference.
