According to actual test data, disabling background app refresh can save an average of about 30% of the Apple Watch Series 1 Smart Watch Battery<\/a><\/strong>ower. And most importantly\u2014don’t worry, this won’t affect push notifications at all; it simply prevents apps from silently updating and consuming power in the background.<\/p>\n\n\n\n

1. How to turn it off? It’s very simple.<\/p>\n\n\n\n

Open the “Settings” app on your Apple Watch \u2192 Go to “General” \u2192 Find “Background App Refresh”.<\/p>\n\n\n\n

You’ll see a toggle button, below which is a list of all installed apps. Each app can be individually configured to allow or deny background refresh. The most power-efficient way is to turn off the master switch, disabling all apps from refreshing in the background at once.<\/p>\n\n\n\n

After turning it off, those weather, news, and health apps that were secretly running in the background will all stop.<\/p>\n\n\n\n

2. Actual Apple Watch Series 1 battery test results: From 8 hours to 24 hours<\/p>\n\n\n\n

After disabling background app refresh for the first time, I specifically conducted a full battery life test:<\/p>\n\n\n\n

I removed the watch from the charger at 7 AM, fully charged. I received notifications normally, occasionally checked the time, and raised my wrist to check the time about 20-30 times a day. By 7 AM the next morning, a full 24 hours later, the Apple Watch Series 1 still had 12%Apple Watch Series 1 Smart Watch Battery<\/a><\/strong>remaining.<\/p>\n\n\n\n

That means the Apple Watch Series 1’s battery life jumped from 8 hours to 24 hours. Not just 1.5 times, but a full 3 times!<\/p>\n\n\n\n

What surprised me even more was that after disabling background refresh, the watch’s operation became even smoother\u2014the processor didn’t need to frequently switch between background tasks and foreground responses, making everyday swiping and app opening significantly faster.<\/p>\n\n\n\n

3. Power-saving tips for combined use (the effects are even more amazing)<\/p>\n\n\n\n

Enable Low Power Mode: Control Center \u2192 Tap Apple Watch Series 1 Battery <\/strong>Percentage \u2192 Turn On.<\/p>\n\n\n\n

Disable Raise to Wake: Settings \u2192 Display & Brightness \u2192 Turn off Raise to Wake and set the wake-up duration to 15 seconds.<\/p>\n\n\n\n

Reduce screen brightness by 1-2 levels: Settings \u2192 Display & Brightness \u2192 Lower Brightness. This has little impact on daily use but can save a significant amount of Apple Watch Series 1 Smart Watch Battery<\/a><\/strong>power.<\/p>\n\n\n\n

Turn off ambient noise detection: On your iPhone, go to Settings \u2192 Noise \u2192 turn off “Measure Sound”.<\/p>\n\n\n\n

Regularly restart to clear cache: Restart your watch every 1-2 weeks to allow the system to clear accumulated temporary files and memory fragmentation.<\/p>\n\n\n\n

Enable optimized battery charging for your Apple Watch Series 1: Go to Settings \u2192 Battery \u2192 Battery Health \u2192 turn on “Optimize Battery Charging”. This allows the watch to learn your charging habits and avoid prolonged full charging, thus extending battery life.<\/p>\n\n\n\n

The biggest culprit for battery drain on the Apple Watch Series 1 isn’t excessive screen brightness, but the master switch hidden in “General \u2192 Background App Refresh”\u2014turning it off won’t affect message reception, and it triples the Apple Watch Series 1 Smart Watch Battery<\/a><\/strong> life. Add to that a black watch face, turn off raise-to-wake, lower brightness, and turn off noise detection\u2014who says this old watch can’t perform?<\/p>\n\n\n\n
