How to Make Your Smartwatch Battery Last Longer: 12 Easy Tips

Your smartwatch should be able to track activity, show important notifications, and support daily routines without constantly searching for a charger. If the battery no longer lasts until the end of the day, the watch may not be faulty. Screen settings, background apps, wireless connections, health sensors, and even the selected watch face can all increase power use.

This guide explains how to make a smartwatch battery last longer using safe and practical adjustments. The tips apply to Apple Watch, Samsung Galaxy Watch, Google Pixel Watch, and many other Wear OS devices. Some menu names may be slightly different depending on your watch model and software version.

Important: Change only one or two settings at a time, then test the watch for a full day. This will help you discover which feature is responsible for the biggest battery drain.

Why Does a Smartwatch Battery Drain Quickly?

A smartwatch has a much smaller battery than a smartphone, yet it performs many tasks throughout the day. It may keep a bright display active, measure health data, receive notifications, connect to Bluetooth or Wi-Fi, search for a mobile signal, use GPS, and refresh apps in the background.

Battery life can also change after installing a new app, switching to an animated watch face, enabling LTE, starting continuous health measurements, or installing a major software update. Poor network coverage can make the problem worse because the watch repeatedly searches for a stronger signal.

Before changing any settings, fully charge the watch and use it normally for several hours. Then open the battery section in the watch settings or its companion phone app. Look for an app or feature using much more power than expected.

1. Disable the Always-On Display

The always-on display keeps the time and other information visible when you are not actively using the watch. It is convenient, but it also forces the screen to remain active for many extra hours each day.

Open Settings, select Display, and turn off Always-On Display. You can still wake the screen by tapping it, pressing a button, or raising your wrist. This is usually one of the most effective changes for improving battery life.

Google also recommends allowing the screen to turn off when it is not being used in its official Wear OS battery guide.

2. Reduce Screen Brightness and Timeout

The display is one of the largest power users on any smartwatch. Maximum brightness may be useful in direct sunlight, but it is unnecessary in most indoor environments.

Reduce the brightness by one or two levels and enable automatic brightness if your model supports it. You should also shorten the screen timeout so the display turns off quickly after you stop interacting with it.

A good everyday setup is automatic or medium brightness with a short timeout. If the screen becomes difficult to read outdoors, increase brightness temporarily instead of leaving it at maximum all day.

3. Choose a Simple Watch Face

Some watch faces use more battery than others. Animated designs, bright backgrounds, moving effects, and multiple live complications require extra processing and frequent data updates.

Try a simple static watch face with a dark background and only the information you check regularly. Start with the time, date, and battery level. You can add weather, calendar, heart rate, or fitness complications later if battery performance remains good.

Dark watch faces can be especially efficient on OLED displays because black pixels use very little power. Avoid downloading watch faces from unknown sources, as a poorly optimized design may continue working in the background.

4. Reduce Unnecessary Notifications

Every alert can activate the display, vibration motor, processor, and wireless connection. If your watch receives notifications from dozens of shopping, gaming, social media, and news apps, these small actions can add up during the day.

Open the watch companion app on your phone and review the notification list. Keep alerts enabled for calls, messages, calendars, security services, and the apps that are genuinely important to you. Disable notifications from apps that you rarely need on your wrist.

This change improves battery life and also makes the watch less distracting. You can continue receiving the disabled alerts on your phone.

5. Limit Background App Refresh

Background refresh allows apps to download new information when they are not open. Weather, news, fitness, calendar, and messaging apps may refresh repeatedly throughout the day.

On Apple Watch, open Settings > General > Background App Refresh and disable refresh for apps that do not need constant updates. Apple includes this recommendation in its official guide on how to extend Apple Watch battery life.

On a Galaxy Watch, Pixel Watch, or another Wear OS device, open the battery usage section in the watch settings or companion app. If one app is using an unusually large amount of power, update it, restrict its background activity, or uninstall it.

6. Turn Off Wi-Fi and LTE When You Do Not Need Them

Bluetooth is normally the most efficient connection when your phone is nearby. Wi-Fi and LTE can use more power, especially when the signal is weak or unstable.

If you usually carry your phone, keep the watch connected through Bluetooth and disable LTE when it is not required. You can also turn off Wi-Fi when the watch does not need a direct internet connection. Remember that disabling these connections may stop calls, messages, streaming, and online apps from working independently.

Do not turn off Bluetooth during normal connected use unless you have a specific reason. The watch may switch to Wi-Fi or cellular data, which could use more battery.

7. Control GPS and Location Access

GPS is essential for accurate outdoor workout routes and navigation, but continuous location tracking uses substantial power. Always end a workout or navigation session when you finish. Accidentally leaving a session active can drain the battery within a few hours.

Review which watch apps can access your location. Allow access only while using an app when continuous tracking is not necessary. If you listen to music during an outdoor workout, download the tracks before leaving instead of using GPS and LTE streaming at the same time.

For long activities, use the watch's low-power workout option if one is available. It may reduce GPS or sensor frequency while still recording useful information.

8. Review Health and Fitness Tracking

Modern smartwatches can monitor heart rate, blood oxygen, stress, sleep, skin temperature, and other health signals. Continuous measurement keeps sensors and processors active, so optional features can affect battery life.

Open the health settings and review how frequently each measurement is taken. Keep the features that are useful to you and reduce the frequency of optional measurements you do not check. Automatic workout detection can also use extra power because the watch regularly looks for movement patterns.

If you rely on a watch feature for a health or safety reason, do not disable it only to save battery. Battery life is important, but it should not replace an essential health need.

9. Stop Accidental Screen Wake-Ups

Raise to Wake turns on the screen when the watch detects a wrist movement. The feature is helpful, but it may activate accidentally while walking, driving, working, or sleeping.

If you often notice the display turning on without intending to use it, disable Raise to Wake and use tap-to-wake instead. You can also enable Theater Mode, Sleep Mode, or Do Not Disturb during periods when you do not need the display and notifications.

These modes are useful overnight, during meetings, or while watching a movie. They reduce unnecessary screen activity without forcing you to change every setting individually.

10. Update the Watch and Its Apps

A software bug can cause an app or system service to run too often in the background. Updates frequently include stability, performance, and battery improvements.

Connect the watch to its charger, use a stable Wi-Fi connection, and check for system updates. Then update the installed watch apps through the App Store, Play Store, Galaxy Store, or the companion app used by your model.

Battery use may temporarily increase after a major update while the watch finishes syncing, indexing, and optimizing apps. Allow a day or two before deciding that the update created a permanent problem. Restart the watch and its connected phone if heavy battery drain continues.

11. Use Low Power Mode or Battery Saver

Low Power Mode and Battery Saver reduce features that consume extra energy. Depending on the model, the watch may limit background updates, screen brightness, network activity, performance, or health measurements.

On Apple Watch

Open Control Center, tap the battery percentage, and enable Low Power Mode. You can select how long it should remain active.

On Wear OS and Pixel Watch

Swipe down from the top of the screen, open Battery Modes, and select Battery Saver. Some models can activate it automatically when the battery reaches a low percentage. Google explains these options in its official guide to making a low watch battery last longer.

On Samsung Galaxy Watch

Open Settings > Battery and enable Power saving. Samsung notes that this mode may limit performance, background functions, and wireless connections. You can read the manufacturer's official Galaxy Watch battery instructions for more details.

Battery-saving modes are ideal when you are traveling, away from a charger, or trying to keep the watch running until the end of the day.

12. Charge the Smartwatch Correctly

Use the original charger or a compatible charger approved by the manufacturer. An unsuitable or damaged charger may charge slowly, generate excess heat, or fail to deliver stable power.

Keep the back of the watch and the charging surface clean and dry. Place the charger in a cool, ventilated area and avoid covering it while the watch is charging. Do not leave the watch in direct sunlight or inside a hot vehicle, because extreme heat can reduce charging performance and accelerate battery wear.

Apple Watch includes Optimized Battery Charging, which learns your charging routine and reduces the amount of time the battery remains completely full. Apple explains how it works in the official Optimized Battery Charging guide. Other smartwatch brands may offer a similar battery protection option.

How to Diagnose Sudden Smartwatch Battery Drain

If your watch previously lasted all day but suddenly begins losing power within a few hours, use the following order:

1. Restart the smartwatch and its connected phone.
2. Check the battery usage page for an unusually active app.
3. Update the watch software and all installed apps.
4. Remove any new app or watch face installed before the problem started.
5. Turn off Always-On Display and unnecessary notifications.
6. Disable LTE, Wi-Fi, or GPS when these connections are not needed.
7. Charge the watch fully and test it through one normal day.

If one change solves the problem, you can gradually restore the other features. This method is more reliable than disabling everything at once because it identifies the actual cause.

When Should You Contact Support?

Settings cannot fix every battery problem. Contact the manufacturer or an authorized service center if the watch becomes unusually hot, shuts down unexpectedly, will not charge correctly, has visible damage, or continues to lose power rapidly after completing the troubleshooting steps.

Rechargeable batteries naturally lose capacity after many charging cycles. An older watch may need professional battery service. Do not try to open a sealed smartwatch yourself, as this can damage the device and its water resistance.
