In today’s day and age, our smartphones continue to get slimmer and slimmer, but battery technology is lagging behind just a little bit. This means that manufacturers are forced to squeeze smaller batteries into devices.

With Android Marshmallow, Google introduced a new feature called “Battery Saver”, which is a feature embedded into the OS to help keep your device going for as long as you are. This feature has stuck around, and other manufacturers have implemented their own battery saver settings to fit each device’s needs.

While there are some more extreme methods for saving battery life on your devices, such as a using black wallpaper, disabling certain features, and others, Battery Saver mode has proven to be quite useful. The steps below are for stock Android 6.0 Marshmallow, but the process should be similar for most phones.

  1. Go to Settings > Battery
  2. Tap the three-dot menu icon in the top right
  3. Select Battery saver
  4. You can turn it on manually, or select Turn on automatically
  5. Choose your desired time

Once Battery Saver has been activated, you will notice a few things right off the bat with your device. First and foremost, the display on your device will likely dim, as the brightness has automatically been decreased. Additionally, there will be a few applications that cannot be used, such as Google Maps, and there is a chance that location services and background data syncing have been turned off.

For some apps such as email, messaging, and others, the syncing will be turned off, but this will be updated and properly calibrated when you open each application. The built-in battery saver mode does everything it can to ensure you can squeeze as much juice out of your battery as possible.

In addition to setting up Battery Saver mode to turn on automatically, there is another easier way for you to activate this process if you choose to. Simply swipe down from the notification shade, and there should be a Battery Saver icon in the shade. This will automatically activate Battery Saver mode, allowing you to save some juice if you’ve been using your device more than usual during the day.
