Google is making it easier to improve your phone’s battery life.

The company has built a new banner into Android, which warns you of any apps that are draining your battery.

It also includes a short explanation of what those apps are doing, and lets you fix the problem by putting a stop to the behaviour.

Limit notifications

Notifications are incredibly useful, but they also drain battery life and not all of them are actually necessary. Switching off notifications for certain apps can help your phone’s stamina. On Android, head into Settings, hit Apps and select those you don’t need to be notified by. On iOS, go to Settings and then Notifications.

Disable auto-sync

Certain apps, such as email and social networks, constantly run in the background even when you’re not using them. This is so you see updated information and updates when you do open the apps, but the benefits can be offset by the amount of battery life auto-sync can eat up. On Android, you can turn off auto-sync by going to Settings, Accounts and hitting the menu button. On iOS, go to Settings, General and Background App Refresh. However, since auto-sync is genuinely useful, we’d recommend disabling it when you know you’re going to be running low on battery life, rather than switching it off all the time.

Switch off location services

GPS is a huge drain on your phone’s battery, as more and more apps use your location data to work out where you are, and shape your experience according to that information. Unless you’re using a Maps app, you can get by without it. To turn off GPS on Android, go to Settings and Location. On iOS, go to Settings, Privacy and Location Services.

Lower brightness

Your phone’s display is responsible for the biggest impact on your battery life, but it’s easy to limit how much energy it uses up. Auto-brightness is convenient, but often sets the screen brightness to a much higher level than it needs to be. Turning auto-brightness off, setting your display’s brightness to a lower level and adjusting it when you need to is much more sensible.

Uninstall apps you don’t need

Some apps drain more battery life than others, and it’s worth working out which ones you can do without. Facebook, for instance, is known to have a big impact on your phone’s battery, and you can eliminate this by deleting the app and using the social network in your web browser instead. On Android and iOS, you can see the apps and processes that are affecting your battery by going to Settings and Battery. From there, work out what you can delete or replace with a less-demanding alternative.

Cut your assistant off

Virtual assistants are becoming increasingly capable, and therefore increasingly important in tech companies’ eyes. Not all consumers share the enthusiasm of Google and Apple though, and rarely - if ever - use Google Assistant and Siri. Whether you use them or not, by default the two assistants are always listening out for their trigger words, and this uses up battery life. On Android, you can switch this off by going to Settings, Google, Search, Voice and “Ok Google” detection. On iOS, go to Settings, Siri and Allow “Hey Siri”.

Stop vibrating

Vibrate is a great middle-ground between a potentially disruptive ringtone and total, uncertain silence, but it also uses up the most battery life of the three options. You can go a step further by also disabling tap feedback, which can be reassuring, but is ultimately unnecessary.

Turn off connections

If you’re connected to a Wi-Fi network, switch your mobile data off, and vice versa. Similarly, remember to turn off Bluetooth and NFC when you’re not using them.

Airplane mode

Airplane mode isn’t just for when you’re on an aeroplane. If you know you’re not going to have or won’t need signal or a Wi-Fi connection for a good amount of time, it’s worth enabling Airplane mode. Otherwise, your phone will use up battery life by pointlessly trying to connect to a network.

The feature was spotted by Android Police, in the latest Android 8.1 Oreo Developer Preview.

While this preview software isn’t available to regular Android users yet, it should roll out in the near future.

The battery page in the current version of Android Oreo displays lots of information, including your screen usage time since your last full charge, how much usage time you have left on your phone, and a breakdown of your app usage.

However, the new battery drain warning system is much more practical, providing a call to action.

The warning message seen by Android Police flags reads, “Maps Preview draining battery. Requesting location frequently.”

Tapping it launches a popup message reading, “Your phone can’t manage battery normally because Maps Preview keeps requesting your location when you’re not using the app. To fix this issue, you can turn off location for this app.”

With a tap, you can instantly stop it from requesting your location when you’re not using the app, and extend your battery life as a result.
