I just picked up my Model X Plaid two weeks ago. I noticed that my battery drains quicker than I though it should. Last night I charged it too 90% and unplugged it at 8pm. Nothing ran in it since and now at 10 hours later its at 86%. Sentry is running but it wasn't warm enough for the overheat to kick in. Is this normal? My Y would drop maybe 1% over night not 4%. Is there a way to calibrate the battery maybe or do I have an issue with the battery pack?
