“when managers troubleshoot, it strengthens the whole team”

How to keep your Galaxy phone from slowing down 

To keep up with the nuts and bolts of your phone’s performance, use the Device care feature. It provides an overview of your battery, storage, and RAM. You can also automatically optimize your phone for faster, better performance. 

Note: Available screens and settings may vary by wireless service provider, software version, and phone model. This feature was previously called Device maintenance.

Quick optimization 

The Quick optimization feature improves your phone’s performance by identifying apps that use excessive battery power. It also clears away unneeded items from memory, deletes unnecessary files, and closes apps running in the background. Optimizing your phone is quick and simple. 

From Settings, swipe to and tap Battery and device care. Tap Optimize now, and then tap Done

Note: The Optimization feature will not appear when Device care determines your phone is in Great condition. 

Use Power saving 

Battery is your phone’s lifeline. There are several ways you can change the battery settings to optimize your phone’s battery life. 

From Settings, swipe to and tap Battery and device care. Tap Battery, and then tap Power saving. Select from the following options: 

  • Turn off Always on Display: Enable or disable the Always on Display feature. 
  • Limit CPU speed to 70%: This puts a limit on your device’s CPU speed. 
  • Decrease brightness by 10%: You can save battery power by decreasing your device’s brightness. 
  • Limit apps and Home screen: This option will alter a few app and Home screen settings, such as limiting all background activity and disabling Edge panels. 

Note: In order to turn these options on or off, Power saving must be disabled. Once you’ve made your desired adjustments, you can turn Power saving back on. 

Clean storage 

If you are worried about your phone being overloaded with unnecessary files, it’s about time you clear out your storage. Happy cleaning! 

  1. From Settings, swipe to and tap Battery and device care.  
  1. Tap Storage, and then tap on a category that has items you’d like to remove, such as Images. 
  1. Touch and hold an item to select it, and then select the additional items you’d like to remove. 
  1. Tap Delete when you’ve selected everything, and then tap Move to Trash

Clean memory 

Is your phone getting glitchy and slow? Clean up your phone’s memory to improve its performance. 

From Settings, swipe to and tap Battery and device care. Tap Memory, and then tap Clean now to free up memory by stopping background apps. 

If you’d like to keep certain apps running in the background, you can tap Excluded apps and add your preferred apps to the list so they do not get closed when you use this feature. 

A more thorough way to clean the phone’s memory is to reboot it occasionally. You can restart the phone any time by swiping down from the top of the screen using two fingers to open the Quick settings panel, and then tapping the Power icon. Tap Restart and then tap Restart again. If necessary, you’ll need to enter your PIN or password when the reboot is complete. 

You can also have the phone reboot automatically on a schedule, such as late at night when you won’t be using it. 

  1. From Settings, swipe to and tap Battery and device care
  1. Tap More options (the three vertical dots), and then tap Automation
  1. Tap Auto restart at set times, and then tap the switch to turn it on. 
  1. Tap the day or days you want to the phone to automatically restart, and then tap Time to choose what time to restart. The phone will automatically reboot at the set time if the screen is off, the phone is not being used, and the battery is at least at 30%. You’ll need to enter your PIN or password to use the phone after the restart, but you’ll still get notifications, and your alarms will go off in the morning!
