Outbyte Driver Updater FREEFix the driver behind crashes, sound loss and screen glitchesFind Drivers →Outbyte PC Repair FREEClear out junk files and repair common Windows errorsFree Scan →If your Apple Watch battery life drops after a watchOS update, Apple recommends waiting a few days and checking again: update-related tasks can continue in the background and may affect battery life. Apple does not identify one specific task as the cause or promise when battery life will return to normal. If you need more runtime now, Low Power Mode is the broadest built-in option, but it limits features.
1. Give the watch a little time after updating
Apple says you can use Apple Watch immediately after updating, even while some update-related tasks continue in the background. If you notice reduced battery life, its advice is to wait a few days and then check again. That is a recommendation, not a guaranteed recovery window: Apple does not specify which background tasks are involved or say that every post-update battery change will resolve on its own. Apple’s battery-drain guidance covers this waiting period.

2. Turn on Low Power Mode for more runtime now
Low Power Mode is the most direct way to reduce power use when you need the watch to last longer before you can charge it. On the watch, press the side button to open Control Centre, tap the battery percentage, then turn on Low Power Mode. Apple’s watchOS 26 guide says you can choose a duration of one, two or three days when enabling it. The mode turns off automatically once the watch charges above 80 percent, according to Apple’s current support article.
Do these 3 things before closing this tab:
1Repair Windows errors before they cause bigger problems2Scan for outdated or missing drivers - takes under a minute3Clear out junk files and repair common Windows errorsThis is a trade-off, not a free battery improvement. Apple says Low Power Mode turns off or limits features including Always On Display, background heart-rate and blood-oxygen measurements, and heart-rate notifications. Some other notifications may be delayed, emergency alerts may not arrive, and certain cellular and Wi-Fi connections are limited. The watchOS 26 guide says the watch can offer Low Power Mode when battery reaches 10 percent. See Apple’s watchOS 26 instructions for details.

3. Reduce background refresh selectively
Apps refreshing in the background can use power. To change the setting, open Settings > General > Background App Refresh on Apple Watch. You can switch refresh off for all apps or disable it for individual apps. Start with apps you do not need updating in the background if you rely on timely information from others. Apple notes that complications displayed on the current watch face continue to refresh even when Background App Refresh is off. Apple’s guide describes the setting and its effect.
4. Adjust display, workouts and connections to fit your use
Display and wake behavior
Turning off Always On can reduce power use, though you will need to wake the display to check it. Apple also lists reducing how often the display wakes as a battery-saving option. The exact controls and availability depend on the watch model and software version. See Apple’s battery guidance.

Phone and network connections
Keep the watch near its paired iPhone when practical: Apple says Bluetooth connection to the phone uses less power than a watch connection over Wi-Fi or mobile networks. If you are away from the iPhone, Apple says Wi-Fi uses less battery than a mobile network. Weak signal conditions use more power; if you expect to be somewhere without useful Wi-Fi or cellular coverage, Airplane Mode may help. These choices can reduce connectivity or availability, so use them where that trade-off is acceptable. Apple advises keeping Bluetooth enabled on the paired iPhone, because turning it off increases Apple Watch battery drain. More detail is available in Apple’s battery-performance guidance.

For supported watches, fewer GPS and heart-rate readings can extend use during long outdoor walking, running or hiking workouts. Apple also documents pairing a Bluetooth heart-rate chest strap to use instead of the watch’s built-in heart-rate sensor during a workout. That is a workout-specific option, not a general fix for day-to-day drain after an update; check compatibility for your watch before choosing a strap. See Apple’s workout battery guidance.

5. Check battery health if the drop persists

If the screen says “Battery Needs Service,” or you believe the battery needs replacement, Apple advises contacting Apple Support. Battery service addresses a battery-capacity or service issue; it is separate from update-related background activity. Apple’s instructions are on its battery-drain support page.
