Direct contextual assistance can now be accessed by touching and holding the home button on Android devices running Marshmallow. The update allows for voice interactions with supported apps, such as asking music questions to TuneIn. Users can also directly share content between apps for specific contacts. Battery life is improved through features like Doze that puts the device in a sleep state when inactive, and App Standby limits battery usage from seldom used apps. The update also enhances privacy, security, and usability.

1. Contextual Assistance
Now on Tap: get assistance without having to leave what you’re doing—whether you’re in an app or on a website. Just touch and hold the home button.
Do more with your voice. Now you can have a dialogue with any of your apps that support the new voice interaction service. For example, if a user says
“play some music on TuneIn,” TuneIn will respond by asking “What genre?”
Direct Share: a fast and easy way to share to the right person in the right app.
Battery
Doze: when your device is at rest, Doze automatically puts it into a sleep state to increase your standby battery life.
App Standby: no more battery drain from seldom used apps; App Standby limits their impact on battery life so your charge lasts longer.
USB Type C support: Quickly transfer power and data all through the same cable. Lightning fast charging gives you hours of power in just minutes.

and still continue to use the app.
