- Unfortunately the Prime does not go to sleep when an app is running, so user must exit app to prevent battery drain or have calculator plugged in while in use

I had the same problem with a program that displayed user tabs using a forever loop and WAIT(-1) command. If I left the program running, it would drain my calculator's battery, even if the screen was in low power mode. I installed a loop counter that counted the number of times the WAIT(-1) loop cycled. If no key or tab was pressed after 5 minutes, the program would exit the loops, go to the end of program, and then exit to the home screen. After 5 minutes in the Home screen, the calculator would naturally turn off. An example of the loop counter is shown in this post. https://www.hpmuseum.org/forum/thread-12...#pid115217
