I bought an iPhone 13 Pro just a week ago and it started with 94% battery health, but now it's down to 92%. This drop seems pretty quick, especially since I usually charge my phone three to four times daily due to gaming, but I only average about two full charge cycles per day. My phone doesn't overheat, and when I'm not gaming, it lasts about 4-5 hours with constant use. I've owned two other phones before this, and one had a similar issue, which I still don't understand. I'm really frustrated with this early battery decline and would love to hear from anyone who might know what's going on.

Have you checked the manufacture date in Settings? It might give you a clue about how fresh your phone's battery actually is.
It's common for batteries to have some initial drop right after purchase, but a 2% drop in such a short time is a bit unusual. Since you're gaming a lot, that can definitely strain the battery, but normally it wouldn't cause such a rapid decrease unless there's a defect. You might want to check if there are any settings that could be draining the battery more than usual, or if there are background apps you're unaware of.
That makes sense, but isn't it just a bit concerning? I mean, isn't a new battery supposed to last longer before showing these signs?

I can't see that info. I think it's only available on the newer models, and mine's just a standard 13 Pro.
