Second-generation Motorola Moto X receives Android 6.0 update
Other features that come with Android 6.0 include the new app permissions, which can be approved or denied on a feature-by-feature basis. Doze puts an inactive phone into a deep sleep. This allows standby time to rise sharply, thus improving battery life. New volume controls are also part of the update.
Since Android 6.0 is being sent out OTA, it won't hit everyone at the same time. Don't panic if it doesn't hit your unlocked second-gen Moto X today, as the notification will eventually arrive. If you are the impatient type, you can go to Settings> About Phone> System updates. When the update arrives, you should make sure that you are connected to a Wi-Fi network before starting the updating process. And you might want to make sure that your battery is charged to at least 50%.
