This app drains iPhone battery – AmpliTube Review

Title says it all. I love this app but even when not using it, just having it installed drains my battery pretty quickly. So I uninstalled it and all went back to normal. I have an iPhone 10s running latest OS. Same thing used to happen when I had an iPhone 6s. Not sure why this is happening. Something is definitely running in the background at all times.
