I/O Summary: How Android M Handles Power And Charging

In the spirit of improving the core Android experience, Google is changing Android M to be smarter about managing power. Their new Doze feature comprises of two primary roles which allow Android to use motion detection in order to predict activity, and go into deep sleep at the right time based on accelerometer readings.


In order to extend your screen off battery life, Android M will now monitor your activity levels and if it detects that your device has not moved in a while will start to “doze”, this means that the device will then wait longer to wake up for scheduled repeating events, whilst not affecting GCM and alarms. When your device is moved, used or plugged in the device will wake up and normal usage will resume.

The second power saving method they have implemented is app-standby whereby if an app is not used for a significant length of time the app will be put into a lower powered state and lose network access until it is used again or your device is plugged in, rather optimistically the length of time they stated during the “What’s new in Android” talk before apps enter standby was measured in days.



They are happy to say that devices running M can last up to two times longer on standby than those running Lollipop. It is important to note that Doze only benefits phones that remain motionless. USB Type C will bring faster charging (according to Google, anywhere from 3 to 5 times as much). And they are, of course flippable and reversible. You can also use your device to charge whatever is plugged in as well.


Hopefully this will see a large increase in the battery life of devices with less screen on time and could have huge ramifications for battery life in tablets which may see much less time being carried around than phones whilst remaining on.
