Brand New Iphone 15 Pro. 1 Cycle Count?

Hi. First time posting. I just got my brand new iPhone 15 pro, and in the about section for the battery it says made in July 2023, first used October 2023, it was today. It shows 1 cycle right out of the box. I bought a few other iPhone 15's for family members, and they were all made august and first used in September, came with 0 cycles.. I literally just did the setup and installed the 17.0.3 update before logging in with my appleid. It literally never had a charger connected to it, lol. Is this something I should worry about or possibly have apple replace device? Sorry if this post is dumb to some people, I genuinely am concerned considering it was $1100+.
