so i just finished completeing the last step in the calibration guide, i followed it right out of the box. the last step is charging it to full one last time. as soon as it hit green i unplugged and turned it on, but for some reason the max time it showed was 5 hours, and then like 10 minutes later it dropped to 3:35 and now its back at 4:46?! im barely running anything or doing anything!! what did i do wrong?
