2020 Sport battery issue

I’ve owned my car for just short of 3 years, and just started having issues at start-up. Car hesitates a little and the dash flickers, then it starts. I had the battery tested, and it was good but only had a 2% charge. Alternator tested good as well. Charged the battery while I was at work, just had it checked again and it’s 50% charged, but still have the issue starting after it sits overnight.

Has anyone else had an issue with parasitic drain on these cars? If so, what was the cause? Any other ideas that someone can throw out at me? I initially thought it was my dash cam, but that’s been in here over a year.

Thanks in advance
