Hello everyone, I'm a noob when it comes to EVs, so bear with me. I just recently brought home a used 2021 model 3 standard range plus rwd. It doesn't come with LFP battery btw. From my understanding, sentry mode is supposed to drain the battery. However yesterday I parked my car at work for 10 hours with sentry mode on at 56% and then when I came back it was 55%. I was also opening the tesla app several times throughout the day. Is this normal? Or is the battery still in the process of calibrating? Should I be worried that I shrieking have less charge than what is showing me?
