Energy Level data empty in Instruments
<p>Trying to pinpoint where my app is eating up phone battery via the Instruments Energy Log.</p>
<p>I record use of the app from an untethered iPhone (<a href="https://developer.apple.com/library/content/documentation/DeveloperTools/Conceptual/InstrumentsUserGuide/MeasuringEnergyImpact.html" rel="noreferrer">as instructed by Apple</a>), and have tried older suggestions.</p>
<p>However, as shown below, Energy Usage Level never show any data:</p>

<p>Why is energy usage level not showing up, even though I am recording the session from an untethered iPhone and importing into Instruments?</p>
