What you need to know about the Android Lollipop is that it also features an in-built Battery Saver mode, which clocks down the CPU, limits vibrations, reduces the ambient light and turns off background data when your device needs a little extra juice. You can turn it on manually or program it to turn on automatically when your battery drops too low. You can also see how much time you have before your phone is fully charged while plugged in, and how much time you have before the battery runs flat. Let’s see how third-party apps react to this.
Talking about the swipe-down quick-settings menu that now lives just above the notification shade, and has a nice sliding animation when you open it. You activate by swiping down with two fingers from the top of the screen. It has controls for a flashlight, aeroplane mode, screencasting and the screen rotation lock. There’s a brightness slider at the top with improved Wi-Fi and Bluetooth toggles below, you can as well as quickly access more advanced settings, and there’s also a shortcut for your phone settings and to switch user accounts.
Smart Lock uses any compatible Bluetooth device, such as the Moto 360, or an NFC tag, to automatically unlock your phone. With the feature enabled, your phone will automatically unlock when it’s close to the Bluetooth device or you tap an NFC tag. When you’re too far away from it, your PIN, password or pattern lock will switch back on.
Not a new feature, but you need to understand that it is now enabled by default on all Android phones and tablets running 5.0 Lollipop, and it helps keep your device safe by scrambling the data on it. This data can only be unscrambled with a special key, which you access with a password you create.
