Samsung reveals simple settings tweak that instantly unlocks extra battery life

Battery life is non-negotiable with our smartphones.

We rely on them to hold everything from personal data to keeping contact and up to date with news. They're part of our everyday lives so it's a major inconvenience if they can't even last us throughout the day.

This might especially be the case if you've had your phone for a while. Rechargeable lithium-ion batteries in smartphones naturally wear down over time.

Thus, they'll hold less charge compared to when they were new.

'Galaxy phones are designed to offer high performance and excellent battery life,' Samsung explained.

'However, battery life depends on how the battery is used and different devices have different battery life.'

Thankfully for Samsung owners, a simple tweaking of the Android settings can get your battery life back up to scratch.

According to the South Korean tech company: 'Long screen time-out settings or high display brightness can substantially reduce the battery.

'To save battery, consider lowering your brightness setting, deactivating auto-brightness, reducing the sleep timeout setting and adjusting your screen resolution and wallpaper.'

To reduce the screen brightness, go to Settings > Display and use the bar to toggle the brightness.

Or, the quicker way is to swipe down from the top of the screen to bring up notifications where there will be the quick-panel slider to adjust screen brightness.

When you change from bright to dim conditions, you might find that the brightness changes automatically. You can deactivate Adaptive Brightness to prevent this setting from being overridden.

Additionally, if your Samsung phone has an AMOLED display (like most recent models), activating Dark Mode across your apps and system display can save battery life. This can also be done in Settings > Display.

Reducing the screen resolution is another way to save battery.

Again, Settings > Display > Change Screen Resolution. Choose one of the left-most options and select Apply.

Finally, reducing the Screen Timeout delay will make a big difference to battery life.

This controls how long the screen stays on since you last touched it. Of course, the longer it's on the more power it's going to use.

By default, it might be set to 30 seconds, but reducing this to the lowest of 15 seconds can conserve power. Yes, the 15 seconds less does make a difference.

To do this go to Settings > Display > Screen Timeout. Tap on 15 seconds.

These small changes can make a noticeable difference in how long your mobile battery lasts throughout the day.
