The timeline pane displays the current energy usage in a bar chart on a scale of 0-20, indicating how much energy your app is using at any given time. These numbers are subjective. If your app’s energy usage level is occasionally high, it doesn’t necessarily mean that your app has a problem. Your app may simply require more energy for some of the tasks it performs. For example, it may use the GPS while performing complex network operations. This is valid energy use. What you should look for are spikes or areas of high energy use that are unexpected or that could be performed at more optimal times.
