According to iOS Battery stats, in the last 24 hours Shapr3D used up the last 20% of my battery even though I used it only until ~2am, where it was just below 25%. I haven’t used my iPad until now (midnight), and it was 4%. I did a screenshot, switched the screen off, and the screenshot popup was on when turned the screen on now.
Please see the screenshot below, Shapr3D was responsible for 92% of battery usage in the last 24 hours.
iOS 15.0, Shapr3D 4.12.1 (1814), on an iPad Pro 4gen 11”
