I am trying to calibrate my AirPods to make them read battery more accurate. I drained them overnight and put them in the case but when I do that the battery reports back at 78-80 percent even though it’s been about 10 seconds. When I try to calibrate my gen 2 AirPods they start off at zero percent but when I try to calibrate my gen 1 AirPods they start off at unusually high percentages. How can I go about fixing this? I have already tried factory resetting and pairing and unpairing.
