Battery consumption is a major drawback for Android users, though it will change thanks to Android Pie's new Adaptive Battery feature. But Google has not said much about the inside of this feature, just publicly said that it uses AI to increase battery life. So we figured out what's really going on under the bonnet.
I'm excited about all the cool new features in Android 9.0. The feature itself sounds interesting when you look at it in Pie's new battery menu and promises to limit battery drain on infrequently used apps by using AI to learn how to use those apps. But how exactly does it work? Let us immerse ourselves.
19659006] 19659007] Adaptive Battery was first unveiled at this year's Google I / O and is one of the few new Android features that use Alphabet's DeepMind AI technology. At the event, Dave Burke, Androgen's vice president of engineering, said the feature could reduce CPU wake-up calls by up to 30% by disabling unnecessary processes.
Because Adaptive Battery relies on machine learning, it will improve over time. It monitors apps to determine your typical usage patterns. What it's really looking for is a list of apps that you do not use often. The system will put these underused apps into a power-saving mode – if you remember the app's app standby feature of Android Marshmallow, it will "hibernate" the apps you did not use, which is very similar. The system now has a number of hibernations that your apps can use depending on their usage.
Here's how it works
The Android Developer Web site provides detailed information about how Adaptive Battery works and what's going on under the hood. Although not explicitly mentioned, Power Management has proven that Adaptive Battery is the front-end to the new App Standby Buckets feature, which aims to allocate system resources to the applications that need them most.
In brief If the Adaptive Battery AI determines how to use a particular app, the app will be placed in one of five App Standby buckets (or "Priority Buckets"). Each bucket has different limitations on the device resources that the apps can use in it. Not only does this process save CPU utilization, it also reduces the transmission of background data – two of the biggest culprits when it comes to phantom power drain.
The following are the buckets and restrictions for apps in them: If you are using the app, the app has started an activity, is performing a foreground process, or is tapping a notification from the app, the app will not be limited imposed.
The good news is that Adaptive Battery does not require any user intervention. It is enabled by default and can be toggled in the settings menu by selecting "Battery" and tapping on "Adaptive battery".
If you're interested, you can see which App Standby bucket the Adaptive Battery AI has placed your apps in by Unlock the hidden Developer Options menu. After opening the menu, open the menu, scroll to Apps and select "Standby Apps".
While the system automatically assigns apps to standby buckets, you can choose a preferred one Select priority group, if you prefer, eg. For example, if you want to impose performance restrictions on an overly intrusive app. Simply tap on App in the above menu and you have the option to manually assign the application as Active, Working Set, Frequent or Rare. Finally, you should know this if you disable Adaptive Battery in the main mode Battery menu, all machine learning seems to be reset regarding your app usage. We do not recommend this, but to test it yourself, you can disable Adaptive Battery and then go back to the standby apps menu in Developer Options. You'll find that all apps have been reset to the active bucket by default  The result
In conjunction with the other power management features of Android Pie, users report remarkable improvements in battery life since Adaptive Battery was activated. As someone who prioritizes battery capacity, I'm looking forward to joining the club … since I've just used Adaptive Battery on my pie update, Google Pixel, it's too early to say if it's one Significant improvement has been made
Since battery capacity is often only the case when the battery is discharged at an abnormal frequency, it is possible that you will not notice the adaptive battery in action, but that's half the point – it does its job Job silent In the background, this means that you spend less time worrying about how you use your phone and more time actually using it.
