There are two main ways to view how much battery is remaining on an iPhone: the battery level icon and battery percentage. Out of the box, the second-generation iPhone SE only shows the battery level icon in its status bar, which only gives you a rough idea of how much juice is left. But there are ways to view the exact percentage instead.
There are plenty of jokes out there about the battery indicator on iPhones. Some people complain about their iPhones dying randomly at 11%, while others see hours of use at the 1% mark.

The Nexus 6 uses an Ambient Display notification system that was heavily inspired by the Active Display feature on the Moto X. Essentially, the device shows a black-and-white version of the lock screen whenever you receive a new notification or pick the phone up.

If you keep sensitive data on your phone, you've surely considered a "lockout" app before. There are many such apps that can add an extra layer of security to other apps within Android. For instance, you can require a PIN or password before anyone is able to launch a particular app.
