Check and optimise the battery on your Galaxy S21

Community Manager




Back in January, Samsung Electronics launched the Galaxy S21. Our latest flagship phone is packed full of amazing features: from its cameras, which can take video in 8K, to its 5G capability and its super smooth 120Hz display, it’s pretty amazing. The S21 also comes with Super-Fast Charging, which gives you hours of power with just minutes of charging.


In fact, the battery is one of the S21’s best features: it can get you through a whole day, and well into the night. This means that you can keep using your phone non-stop, without having to plug it in until you get home. However, you might want your battery to last even longer so that you can make the most of even more of the S21’s features without worrying about charging. If this is your case, then this hack is for you.


Monitor the battery performance using Members app


Please note: you will need a Samsung Account to use the Members App


  1. Open the Samsung Members app and then tap Get help down at the bottom of the screen
  2. Open the Interactive checks section and tap Battery
  3. You’ll see information about how well the battery is functioning
  4. If the result for battery life is Bad, you’ll need to visit a Samsung Support Centre

Optimise battery usage with Adaptive battery


  1. Swipe down from the top of the screen to reveal the Quick settings panel
  2. Tap the Settings icon. It’s a little symbol that looks like a cog up in the top right corner
  3. Scroll down to Battery and device care. If you can’t find it, you can search for it using the magnifying glass symbol at the top of the screen
  4. Tap on Battery and then More battery settings
  5. Toggle the switch next to Adaptive battery. This way, you can limit how much battery is used by apps that you don’t open very often


Save battery power with Motion smoothness


  1. Swipe down from the top of the screen to reveal the Quick settings panel, then tap the Settings icon
  2. Select Display then tap on Motion smoothness
  3. If the screen refresh rate is Adaptive, change it to Standard
  4. This will help you to save battery by reducing the refresh rate of your screen
  5. Select Apply to confirm

Galaxy Unpacked January 2021: What was announced?

Use a static image one the home screen instead of an animated background. Common sense really, also turn off any UI features you find you aren't using like Samsung Free, Edge panels etc. Delete any additional home screens too. The same applies to the lock screen, use a static image and turn off any unwanted widgets
Forgot one other thing, use the accessibility option to reduce animations

I want to give feedback about newest Galaxy (20 and 21). For me it is really disappointing - why Samsung get rid of jack and SD? A lot of people still using jack headphones - I know, I can use adapter but what when I want to charge my smartphone and listen to music!!?? I do like this very often... What with SD card in newest Galaxy? On the other hand a lot of people aren't using dual SIM!!! So Samsung could do SD with ONE SIM!!! In my opinion telephone witch is price is above 800$ should have this options... It isn't cheap... I really wanted to buy Galaxy S20 or S21 but I can't do this - I never gonna buy smartphone without jack and SD. Sorry Samsung... bye....
