Turn off features you are not using right now
The fastest way to extend your Samsung's battery life is to disable the radios and services running in the background. Open Settings, then go to Connections. Turn off Bluetooth when you are not pairing devices, Wi-Fi when you are away from your network, and NFC if you do not use mobile payments. Each one drains power even when you are not actively using it.
Location services are another major drain. Go to Settings > Location and switch it to Battery Saving mode instead of High Accuracy. This tells your phone to use cell towers and Wi-Fi networks to pinpoint your location instead of the GPS chip, which consumes far more power. Apps like Maps will still work, but less precisely.
If you use Samsung's Always On Display feature, disable it or set it to show only at certain times. This small screen stays lit even when your phone is locked, and it adds up over hours. Go to Settings > Lock Screen > Always On Display and turn it off, or tap Customize to set a schedule.
Key Takeaways
- Turning off Bluetooth, Wi-Fi, and NFC when you are not using them stops background power drain from these radios.
- Switching Location to Battery Saving mode uses cell towers instead of GPS, cutting location power use significantly.
- Lowering screen brightness and enabling Adaptive Refresh Rate reduces the display's power draw, which is usually your phone's biggest battery consumer.
- Closing apps running in the background and disabling notifications from apps you rarely use prevents constant wake-ups that drain the battery.
- Enabling Power Saving Mode or Medium Power Saving Mode limits processor speed and background activity, extending battery life by several hours.
Lower your screen brightness and refresh rate
Your display is the single largest battery consumer on your Samsung. Go to Settings > Display and lower the brightness manually, or enable Adaptive Brightness to let the phone adjust it based on your surroundings. Even dropping from full brightness to 40 percent can add hours to your battery life.
If your Samsung has a high refresh rate screen (90Hz, 120Hz, or higher), it refreshes the display more times per second, which uses more power. Go to Settings > Display > Motion Smoothness and select Standard instead of the highest option. Your screen will look slightly less fluid, but the battery savings are real. Alternatively, enable Adaptive Refresh Rate, which automatically drops the refresh rate when you are not scrolling.
Enable Power Saving Mode
Samsung includes built-in power modes that automatically cut battery drain. Swipe down from the top of your screen twice to open the full Quick Settings panel. Look for Power Saving Mode or Medium Power Saving Mode. Tap it to turn it on.
Power Saving Mode limits your processor speed, reduces screen brightness, and restricts background app activity. It typically extends battery life by 4 to 8 hours depending on your usage. Medium Power Saving Mode is less aggressive and still lets most apps run normally. If you want maximum battery life, use Power Saving Mode; if you want a balance, use Medium.
You can also set your phone to automatically switch to Power Saving Mode when the battery drops to a certain level. Go to Settings > Battery and Device Care > Battery > More Options and toggle on Adaptive Battery. This learns which apps you use most and prioritizes power for them while cutting it elsewhere.
Close apps running in the background
Apps continue to run after you close them, checking for notifications, syncing data, and refreshing content. Go to Settings > Apps and select an app you do not use often. Tap Battery and set it to Restricted. This stops the app from running in the background entirely. You can still open it manually when you need it.
For apps you use but want to limit, choose Medium or Optimized instead. Repeat this for any app that drains power without adding value to your day. Social media apps, news apps, and games are common culprits.
You can also see which apps are using the most battery. Go to Settings > Battery and Device Care > Battery and scroll down to see the list. If an app you rarely use is in the top five, restricting it will make a noticeable difference.
Turn off notifications and sync for apps you rarely check
Every notification wakes your phone's screen and processor, even if you do not look at it. Go to Settings > Notifications and review which apps are allowed to send them. Disable notifications for apps you do not need to hear from constantly—news apps, social media, games, and shopping apps are good candidates.
Background sync is another hidden drain. Apps like email, calendar, and cloud storage sync data in the background on a schedule. Go to Settings > Apps, select an app, tap Permissions, and turn off Background Activity if the app offers that option. You can still open the app and manually refresh it when you want.
Disable features tied to your Samsung account
Samsung's cloud services sync your data constantly. Go to Settings > Accounts and Backup > Accounts > Samsung Account and tap Sync Settings. Uncheck Gallery, Notes, Reminders, and any other service you do not actively use. If you only need email synced, leave that on and turn the rest off.
Similarly, go to Settings > Google and review what Google services are syncing. Turn off Backup, Location Accuracy, and Web & App Activity if you do not need them. These services run in the background and check in with Google's servers regularly.
Check for battery-draining software issues
Sometimes a single app or service malfunctions and drains the battery far faster than normal. Go to Settings > Battery and Device Care > Battery and look at the list of apps using power. If one app is using 20 percent or more of your battery and you do not use it heavily, that is a sign something is wrong.
Try uninstalling the app or clearing its cache. Go to Settings > Apps, select the app, tap Storage, and tap Clear Cache. If the problem persists, uninstall it and reinstall it from the Google Play Store. If the battery drain stops, the app was the culprit.
If no single app stands out, your phone may have a software bug. Check Settings > About Phone > Software Update to see if an update is available. Install it if one is there. If battery drain started after a recent update, you may need to wait for a patch or do a factory reset as a last resort.
Frequently Asked Questions
Does turning off 5G save battery on my Samsung?
Yes. 5G uses more power than 4G LTE because it requires a separate radio and stronger signal processing. Go to Settings > Connections > Mobile Networks > Network Mode and select 4G/LTE instead of 5G. You will have slower data speeds, but battery life will improve noticeably.
What is the difference between Power Saving Mode and Medium Power Saving Mode?
Power Saving Mode is more aggressive—it cuts processor speed more, limits background apps heavily, and reduces performance. Medium Power Saving Mode is gentler and lets most apps run normally while still extending battery life. Use Power Saving Mode when you need maximum battery life; use Medium when you want a balance between performance and battery.
Will disabling background app refresh stop important notifications?
It depends on the app. Email, messaging, and phone calls usually still come through because they use system-level services. Social media and news app notifications may be delayed or not arrive until you open the app. If an app is critical, leave its background activity on and restrict less important apps instead.
Does using dark mode save battery on my Samsung?
Only if your Samsung has an AMOLED screen, which most newer models do. AMOLED screens turn off individual pixels to display black, so dark wallpapers and dark-themed apps use less power. If your phone has an LCD screen, dark mode makes almost no difference. Go to Settings > Display > Dark Mode to turn it on if you have an AMOLED display.
Why is my battery draining fast even after trying these steps?
The battery itself may be degraded. Go to Settings > Battery and Device Care > Battery Health and check the status. If it shows "Poor" or "Degraded," the battery has lost capacity and needs replacement. You can also check if a recent app update or system update caused the problem by looking at when the drain started.
