I had massive battery drain on one of my 4 iOS devices (iPhone 12 Pro). I went to the battery settings and saw that the Amazon app was using about 60% of my power, even while the screen was off, causing my battery to almost completely drain in about an hour. I solved it by rebooting my phone. No more battery drain issue.
