Manage Battery Performance on Android Oreo

Edited by Jay

The latest Android-powered phones are feature rich mini-computers with more processing power than some desktops and laptops from a couple of decades ago. All this power packed into such a small case comes at a price, however, and we're not just referring to the retail cost. Battery life is something you'll hear all smartphone users gripe about at some point or another. If you're someone that uses their phone to watch a lot of videos/music or to take photographs and record video, you've no doubt quietly (or loudly) cursed your battery. Likewise, if you use a wide variety of applications and have a tendency to leave them open, you'll most likely notice that the battery drains quicker than if you only used the device to call and text.

The Good news is, Android Oreo (and some older versions such as Nougat and Marshmallow) have a variety of options to help maximize battery life. When Oreo first launched several users complained about poor battery performance. However, it seems to have improved substantially with the 8.1 update (at least on certain devices).

In the following VisiHow tutorial we'll cover battery management (and a few battery saving tips) on a Google Pixel running Android Oreo 8.1.0.

Please keep in mind that not all devices use power at the same rate due to hardware and other environmental differences (exposure to colder temperatures for example).

Advanced Battery Usage

    To allow your display to adapt to the available light, enable "Adaptive brightness". When this is on, your screen will adjust itself based on the amount of light in your environment.

    This is a great way to extend the life of your device's battery.

    Next, we come to the "Sleep" option. Tap it, then select how long your device waits until it goes into sleep mode after inactivity (turns off the display).

    The shorter the time, the longer your battery will last.

    The last feature in Power management is "Ambient display". Tap this for additional power saving options.

    Tap "Double-tap to check phone", then toggle the switch on or off. When this is enabled, you can quickly check for notifications by double-tapping the screen while the device is in sleep mode.

    Next, tap "Lift to check phone". Toggle the switch to enable/disable this option.

  11. 11
    The last option inside Ambient display is "New notifications". Disable this, and the display won't turn on upon receiving new notifications.
    NorthernTouch battery-oreo-16.png
    A good trick is to disable it, but enable Double-tap to check phone. This way you can still check for notifications without fully waking the screen.

    Tips, Tricks, and Warnings

    • Make use of Adaptive brightness whenever possible as the display is one of the biggest power drainers.
    • Set Sleep Mode to kick in sooner (15-30 seconds).
    • Try not to let your battery drop too low before charging. Sometimes this is difficult but whenever possible, top up your battery as it will ultimately extend its life and performance.
    • Try not to expose your device to frigid temperatures for extended periods of time.
    • Keep your device and all its apps updated regularly. Running an outdated version of an app can have adverse effects on battery performance.
