    Fix 4: Force quit apps

    Apps running in the background are heavy battery consumers. These apps although not in use, occupy space on the operating system of the device and are considered as running app. These apps are of no use when kept in the background and also eat up space and consume battery. Hence, we recommend you to force quit the apps which you aren’t using currently. This way, the battery consumption can be reduced further and the Apple watch battery drain issue can be controlled.

    Fix 5: Disable background app refresh

    In Apple devices, apps such as Instagram, Facebook, WhatsApp keep auto-refreshing i.e. they keep reloading again and again. This reloading of apps consumes unnecessary battery. Well, there’s a quick fix to this, head to the watch app on your iPhone and tap “General” > “Background App Refresh”. Turn off the “Background App Refresh” for the apps.
