Samsung Galaxy S21 battery tips
Lower the display brightness
It’s no surprise that the brightness of the display is one of the biggest battery users. So try to use the smartphone at an adequate level of brightness making your smartphone last long.
Switch to full HD+ (S21 Ultra only)
It’s the default setting for Samsung’s phones for a reason – because higher resolutions eat more battery life. Again, the instructions are above, but head to settings > display and you’ll find the option.
Turn on dark mode across your device
There’s some evidence that using dark mode lowers the power the phone needs to illuminate all those white backgrounds. Again, it’s in the display settings.
Turn off features you aren’t using
Samsung phones come fully loaded with features and you’re not going to use them all. In many cases, you can turn them off. That might include everything to do with Bixby, NFC, the second SIM card slot, edge panels, edge illumination, all the vibration notifications.
View what’s eating battery
Head into settings > battery and device care and tap battery. This will show you the predicted battery usage based on your 7-day averages, and tapping the “battery usage” will show you what’s using up that battery.
Look at your battery usage history
On the battery usage page detailed above, you can tap through the graph to see what your usage was on the last 7 days. Scrolling down the page will reveal the apps that used the most battery.
Engage power-saving mode
Either hit the shortcut in quick settings, or head into settings > battery and device care > battery. Here you can turn on power-saving mode, with some options for what actions are taken to save your battery.
Use Wireless PowerShare
The Samsung Galaxy S21 can reverse charge wirelessly. There’s a quick settings toggle for the function that will let you charge another device when you place them back to back. Just tap the button and then place the other device on the back of the Galaxy S21 be that Samsung Buds Pro, an iPhone, or any other Qi device.
Time till fully charged
Charge time is displayed when connected to a charger. Look at the bottom of the lock screen and in the battery status screen. If you’re fast charging, it will say so, and the estimated time left.
