The tips below will show you how to get the best out of your Samsung Galaxy Note 20 series battery in everyday usage.

Adjust display settings

Adjusting the display setting in Galaxy Note 20 series to the long screen time-out settings or high display brightness can substantially reduce battery time.

Lower your brightness setting by pulling down the notifications menu and using the slider to adjust the brightness. You shouldn’t need full brightness unless you are outside in direct sunlight.


  • Go to Settings,
  • Then tab to Display.
  • Adjust the slider until you reach your desired brightness.

Reduce the screen refresh rate

A higher screen refresh rate such as 120Hz, allows you to enjoy an enhanced experience while reading articles, watching movies, and playing games. On the flip side, it also consumers a massive amount of battery life to give you a perfect graphics performance. However, turning off the high refresh rate could help you to greatly reduce the power consumption and provides you more long battery performance.

Adjust the refresh rate

  • From Settings, search for and select Motion smoothness.
  • Tap Motion smoothness again, and then choose your desired option.
    • Standard refresh rate – 60 Hz refresh rate, use this if you want to save your battery life.
    • High refresh rate or Adaptive – 120 Hz refresh rate, which will have all the benefits we discussed.

Note: 120 Hz refresh rate is not supported on WQHD+ resolution. If you switch to this resolution, the refresh rate will drop to 60 Hz. 

Reduce Display resolution:

Similar to a Higher refresh rate, Samsung Galaxy Note 20 Ultra also comes with Quad HD+ resolution, which allows you to watch content in high quality but it also takes a big part of Note 20 Ultra’s battery life.

  • Swipe down the notification panel and tap on the Setting icon.
  • Scroll down and tap on Display.
  • Tap on Screen resolution.
  • Choose resolution:
    • HD+ (1544×720)
    • FHD+ (2316×1080)
    • WQHD+ (3088×1440)

Turn off Always On Display (AOD) or set schedule

Always On Display or AOD uses AMOLED displays to show you certain information when your screen is ‘off’. It allows you to easily check basic information such as date and time without activating the display.

Naturally, any activity that makes your screen turn on all the time will consume some power from your battery. You can choose to turn off AOD or set a time schedule for AOD to turn on/off.

To turn off AOD:

  • Go to Settings > Lock screen and security > Lock screen and Always On Display.
  • Turn off AOD by tapping on the AOD slider.

Power Saving Mode

Your device has a Power Saving Mode. Power Saving Mode differs slightly between devices but generally, it will close all unnecessary apps and screens so that you can essentially increase your battery time.

To enable Power Saving Mode in Note 20 series, follow the below steps:

Medium power-saving mode

  • From Settings, search for and select Battery.
  • Tap Power mode and then tap Medium power saving, review the mode’s settings, and then tap Apply.

Maximum power-saving mode

  • From Settings, search for and select Battery.
  • Tap Power mode.
  • Then tap Maximum power saving, review the mode’s settings, and then tap Apply.

Optimized power-saving mode

  • From Settings, search for and select Battery.
  • Tap Power mode, and then tap Optimized.

Device data synchronize

Samsung Galaxy consists of a number of apps. Out of that, email, or social media, these apps will frequently sync, or check for new emails or updates. Frequently syncing can reduce your battery life.

To check the sync settings in Galaxy Note 20 series in your apps or email, and ensure they only sync as often as you need them to.

Disable Auto Sync

  • Go to Settings.
  • Choose Cloud and accounts.
  • Choose Accounts.
  • Tap three dots for more options.
  • Tap Disable auto-sync to turn off auto-sync of all accounts.

Number of signal bars

If you use your device for long areas of poor response, your device will use more power to communicating with your network operator.

The use of mobile data in areas with a low signal can use a lot of power. Switch off mobile data if you are running short of battery and don’t need it.

Wi-Fi, Bluetooth, and GPS

Switch off Wi-Fi, Bluetooth, and GPS if you don’t need them, as each regularly checks for a signal which uses power.

You can switch each of these off by pulling down the drop-down menu and tapping the relevant icon.

Apps and Multimedia

Apps and content that keep the device awake over an extended period of time can quickly drain the battery (e.g.playing games or watching movies). Some apps are particularly power-hungry, especially if they use features like GPS.

Ensure you close apps when not in use, and if you are out and about and using apps that you know are power-hungry, consider investing in a rechargeable battery pack if you do not expect to have anywhere to charge your device.

Charging your device in the right way

If your battery is charging slower than you expect, make sure you are using the right charger as the amperage on chargers can differ.

– Always use an official Samsung charger, preferably the one that came in the box. If you need to replace your charger, check that the amperage of your new charger is appropriate for the model of your device.

– The power output of where you plug in your device will also affect charging time. Charging your device directly from a power outlet will charge it faster than if you plug it into your laptop.

Minimize hot and cold exposure.

Extreme heat and cold can damage your battery. And continuous use or charging in extreme temperatures may accelerate battery temperature. Samsung’s battery is designed to perform best at 0°-35°C.

  • From the Home screen, swipe up on an empty spot to open the Apps service.
  • Tap Settings > Device care > Battery.
  • Tap Power mode then selects from the following:
    • High performance
