Normal is a battery analytic app designed to help you get the most battery life out of your device.
Actual battery time remaining: This is one of the most practical and useful features of this app. On the iPhone typically, you only get a rough idea about how much battery power you have left and no real indication of what that means in practical terms. Normal tells you how much longer your phone will last with its current battery life and under the workload you currently have it under.
Comparison to other phones: The app compares the settings you use in a given app to how other users have their apps configured. If there are settings you could change that would result in a more efficient use of battery power, the app will inform you.
Graphic interface: The visual representation of how much battery a given app consumes is very clear and easy to understand. The use of design and color makes it very easy to see which apps are sucking the most juice, enabling you to turn them off immediately.
A few bugs: The app seems to get confused about some apps after you've shut them down. Normal did exhibit cases where it thought an app was still running and draining battery when, in fact, it had been closed.
There might be a few bumps in the road still to surpass in Normal's development, but the app is a fantastic tool. The ability to implement best practices in order to prolong your iPhone battery life is very useful. One of the biggest drawbacks of the iPhone itself has always been its short battery life, and this app helps to negate that drawback to the phone.
Using Normal is simple: Install and run the app, perform any actions it suggests (at your discretion), and watch as your battery life increases!
Normal works by collecting generic usage data on your device over time--including what apps are running, what type of device you have, and the battery level--and aggregates it on our cloud platform. Normal then analyzes this data, along with data from all our other users, with proprietary statistical algorithms designed at UC Berkeley's AMP Lab. The results, in the form of suggested actions and statistics about the battery impact of your apps, are then sent back to you.
