Android O

• Battery life

Improving the battery life is one of the biggest and most welcomed features of Android O. Similar to iOS, Android O will limit and manage what apps do in the background while multiple apps are open.Google has added additional automatic limits on what apps can do in the background which fall in three main areas – implicit broadcasts, background services and location updates.

• Notifications channels

Notifications have always been one of the good features of Android. In O, you can group your notifications into channels or as Google describes it: "app-defined categories for notification content". So if you had a channel of apps that are all "news" related, you could interact and control notification settings for all the apps in the news channel at once. This could be a great feature in upcoming Android O.
