Battery performance depends on usage patterns. If you spend a lot of time staring at your phone’s screen and have apps running in the background, the battery will deplete faster. Besides the tweaks mentioned in this article, you should also check out the ADB commands for battery optimization.

1. Switch to Light Performance Profile

One UI 6 and 7 allow you to choose between different processing speed modes. Follow the steps below to enable Light or Optimized performance mode on your Samsung Galaxy device.

1. Open Settings, look for Device Care, and tap it.
2. Select Performance profile under Device Care settings on Samsung devices with One UI 6.1.
3. Select Light to enable the light performance mode.
4. If you own a Samsung device running One UI 6, go to Settings > Device Care > Processing speed and enable Optimized.

2. Reduce Display Brightness

Keeping the display brightness on the lower side can extend the battery life. A brightness level between 35% and 50% is good for your eyes and your phone’s battery.

If you spend most of the time outdoors in sunlight, you may need to set the brightness level to 75-100%. Enabling the Adaptive brightness setting on your Samsung device can save you from constantly adjusting the brightness level.

1. Swipe down from the Notifications bar to open the Quick Settings panel on your device.
2. Tap the 3-dot icon on the Brightness bar.
3. Tap the toggle button next to Adaptive Brightness and select Done to enable it.

3. Set the Screen Refresh Rate to 60Hz

High-end Samsung smartphones feature up to a 120Hz refresh rate. While a higher refresh rate makes animations and screen transitions smoother, it also demands more battery and CPU. To enjoy a longer battery life on your Samsung device, you should consider lowering the screen refresh rate to 60Hz.

1. Open Settings and select Display.
2. Tap the Motion Smoothness option. By default, Adaptive mode (120Hz) is enabled.
3. Select the Standard mode to set the screen refresh rate to 60Hz and tap Apply.

4. Switch to the Dark Mode or a Dark Theme

In dark mode, most of the dark pixels are turned on, which translates into lower battery consumption. Dark mode can save up to only 3-9% of battery power, depending on usage patterns, and save your eyes from strain.

Switching to Dark Mode on a Samsung Galaxy device is very easy. Swipe down from the Notifications bar to open the Quick Settings panel and tap the Dark Mode shortcut located below the brightness bar.

You can also switch to the Dark Mode from Settings > Display > Dark.

If you do not like the default dark theme, we have a handpicked list of the 30 best dark themes for Samsung One UI. Dark themes reduce battery usage and make your Samsung device’s UI a treat to the eyes.

5. Reduce the Screen Timeout Duration

If your phone’s screen remains on for long durations, especially when not in use, it’ll consume more battery. Moreover, it increases the chances of accidental screen touches. You can enjoy a longer battery life by setting the screen timeout to 15 or 30 seconds.

1. Open Settings > Display on your Galaxy device.
2. Scroll down and look for Screen timeout.
3. Set the screen timeout duration to 15 seconds or 30 seconds.

6. Decrease Screen Resolution

If you use your Samsung Galaxy device at the highest display resolution, its battery may deplete faster. All high-end Samsung phones come with QHD+ resolution. While high resolution produces sharp visuals, it also hogs battery juice. You can save battery power by switching to a lower display resolution while maintaining the visual experience.

1. Open your device’s Settings.
2. Tap on Display and select Screen Resolution.
3. Now select FHD+ and tap on Apply.
4. If you have an FHD+ device, you can go down to HD+.

7. Put Unused Apps to Sleep

Upon checking the apps installed on your phone, you’ll discover many apps you use occasionally. You can stop apps from running in the background by putting them to sleep. Samsung One UI 6 settings allow you to manage unused apps and reduce battery consumption.

1. Open Settings, navigate to Battery, and tap it.
2. Tap the Background usage limit option.
3. Tap the toggle next to the Put unused apps to sleep option to add unused apps to the sleeping list automatically.
4. You can also add or remove apps from the sleeping list manually. Tap the following options.
   • Never auto-sleeping apps
   • Sleeping apps
   • Deep sleeping apps
5. Then tap the ‘+‘ icon in the top-right corner of the screen, select the apps, and tap Done.
6. To remove an app from the sleeping list, navigate to Sleeping Apps, tap the 3-dot icon in the top-right corner, and select Remove.

1. Navigate to and open Settings > Battery > Background Usage Limits.
2. Tap the 3-dot icon on the top-right corner of the screen and select Adaptive Battery.
3. Tap the toggle next to On to turn it off.

9. Debloat Your Samsung Galaxy Device

Samsung phones come with hundreds of apps preinstalled out of the box. While some are essential to the Android system, many are useless to the end user. Such apps are known as bloatware because they hog the device storage, track activity, run in the background, and cause battery drain.

You can uninstall system apps on Samsung devices via ADB, Universal Android Debloater, and ADB AppControl, and save battery and storage space. We have a carefully created Samsung bloatware list to help you.

10. Turn off Always On Display

Always On Display leverages the OLED’s capability of turning individual pixels on or off. AOD shows the date, time, and other information. Though the feature uses a small number of pixels without activating the whole display, it still consumes battery. You can either completely turn off Always On Display or at least schedule it.

1. Navigate to and open Settings > Lock screen and AOD.
2. To turn off AOD, tap the slider next to Always On Display. If you want to set a schedule, tap the option itself.
3. Tap When to show > As scheduled > Set schedule and select the start and end time for AOD.

11. Use Intelligent Wi-Fi Features

When Wi-Fi is turned on, your device constantly searches for available networks, which drains the battery. Since manually toggling Wi-Fi on and off is inconvenient, you can automate the process. Samsung Galaxy devices running One UI 6 and 7 have the Intelligent Wi-Fi feature to save battery.

1. Open Settings on your Samsung device.
2. Tap Connections, then select Wi-Fi.
3. Tap the 3-dot icon in the top-right corner of the Wi-Fi settings screen and select Intelligent Wi-Fi.
4. Now, you’ll have various Intelligent Wi-Fi features at your disposal. Tap the slider next to the following options to save battery on your Samsung Galaxy device.
   • Turn Wi-Fi on/off automatically
   • Wi-Fi power-saving mode

12. Disable Nearby Device Scanning

Device scanning is a background process that drains the battery. Turning it off can save some battery power. Go to Settings > Connections > More connection settings and turn off Nearby device scanning by tapping the toggle.

1. Navigate to and open Settings > Device Care on your Samsung phone.
2. Tap the Optimize Now button.
3. To automate this process for periodic checks, tap Auto Optimization > Auto Restart.
4. Next, tap the toggle next to Restart on schedule and set the time and days of the week.

15. Enable Power Saving Mode

The Power Saving mode disables background location checking, data syncing, UI animations, 120Hz screen refresh rate, AOD, 5G, etc. Moreover, it decreases CPU speed to 70% and display brightness by 10%. It extends the battery life, but at the same time, it may impact the user experience. Therefore, it’s a good idea to customize the power-saving mode before enabling it.

1. Navigate to and open Settings > Battery > Power saving.
   • Before enabling the Power Saving mode, do the following.
   • Turn off Always On Display: ON
   • Limit CPU speed to 70%: ON
   • Decrease brightness by 10: ON
   • Turn off 5G: OFF
   • Limit app and Home screen: OFF
2. Having done the tweaks, tap the toggle next to the Power Saving option to enable it.
3. If you are curious, below is a comparison of battery life before and after enabling the Power Saving mode after customization.

16. Use Modes and Routines

On Samsung devices with One UI 6 and 7, you can decide how your phone behaves while at home, sleeping, driving, exercising, at the workplace, etc. Once you configure what setting you want to override or what setting you want to add when specific conditions are met, your device will automate things for you. For example, you can set custom volume levels, notifications, power-saving modes, display brightness, AOD, and restrict apps for different modes.

The Modes and Routines feature can help you stay focused, avoid distractions, and save battery.

1. Open Settings and tap Modes and Routines.
2. Select a Mode from the list or tap Add mode to create a custom mode.
3. Tap Start and set your preferences for the mode.

The following battery charging tips will help you ensure that your Samsung phone’s battery charges efficiently and its lifespan is longer. You can check the battery’s health, its charge cycle count, and current capacity using ADB.

• Do not let your phone’s battery drain below 20% and charge it over 80 or 85%. You can enable the Battery Protection feature from Settings > Battery.
• Disable wireless charging, as it doesn’t charge the device efficiently and causes overheating, which is bad for the battery’s health.
• Fast-charge your device only when necessary. Slow charging at 5~10W (5V 1A, 5V 2A) is good for a longer battery lifespan. Remember, slow but steady wins the race. Go to Settings > Battery > Charging settings and disable Fast charging.

18. Disable Sending Diagnostic Data

Android devices send diagnostic, device, and app usage data to Google and their respective manufacturers. The option is enabled by default and uses mobile data and battery juice.

1. Go to Settings > Security and Privacy.
2. Look for More privacy settings and tap it.
3. On the next screen, tap the toggle next to the Send diagnostic data option to disable it. Your Galaxy device will no longer send data to Samsung.
4. Now, tap the Usage and Diagnostic option located at the bottom of the same screen and disable it.

19. Disable Background Data Usage

While apps related to calling, social media, email, messaging, maps, etc., use data in the background to function properly, we can safely disable background data usage for others. Doing so will save data and battery.

1. Open Settings on your Samsung phone and go to Connections > Data Usage > Mobile Data Usage.
2. Now tap the app you want to restrict from using data when not in use and turn off the toggle next to Allow Background Data Usage.

20. Enable Process Data only on This Device

Samsung introduced more than 16 Galaxy AI features with One UI 7. While some AI or Advanced Intelligence features use device resources, many others process data online. By disabling online data processing, you can enhance your privacy and save battery on Samsung Galaxy devices.

1. Open Settings and navigate to Advanced Features > Advanced Intelligence.
