Power Reserve disappointment on my 2017 36mm datejust?

This was my first Rolex ever and it has a lot of sentimental value to me however, when I first bought it brand new back in 2017 I noticed that the 48 hour power reserve seem to only last about 24 to 36 hours at most. I immediately took it back and had them send it to Rolex who inspected the Watch and said there was nothing wrong with it. I wear it at a desk job throughout the day so not a ton of movement however, there should be enough where the power reserve is so weak. As I’ve got more Rolex’s (I know that power reserves have increased to 72 hrs and different Rolex’s have different movements so you can’t compare apples to oranges) it’s made me realize even more so how disappointing the power reserve is on this watch. Is this one somehow a lemon even though Rolex has inspected it and said that there’s nothing wrong? Is it just the datejust with the 48 hour reserves that don’t seem to hold the power? Frankly, it seems like a huge disappointment as far as product performance from Rolex, but I don’t wanna give up on this watch because of the sentimental value.
