I recently got my iPhone 15 in August of 2024 so not even a full year yet. My battery life rapidly goes down during a normal day. When I got this phone I had a iPhone 13 that was about 2 almost 3 years old. And the maximum capacity was about 79-81% when I traded it in. Not my 15 is already at 91% with 251 charges. Can anyone give me answers?

Battery health decline isn't exact. On average for every 50 cycles, one would see about a 1% drop in battery health. Given you've been through 251 cycles, one would expect your battery to be in the 94 - 95% range. So yes, it's a little lower than expected at this point. But there are many factors which can affect battery health. For example, letting the battery fully discharge ages a battery faster. You shouldn't let the battery go below 20% very often. Some people may push the battery harder doing things like heavy gaming, making videos, using the camera a lot.
At this point it doesn't appear there is an issue with the battery, but if you push your phone harder, your battery health may decline faster. When the health of your battery dips to 80%, that's when you need to pay Apple to replace the battery in your iPhone.

Based solely on your charge cycles, I would expect your Battery to be at 94%-95% Maximum Capacity, so on average it is lower by 3 or 4% than what would be expected.
For your rapidly declining battery, post the screenshot at Settings > Battery where it shows your green graph over the last 24 hours including the top 5 apps. Some apps particularly stand out as being battery hogs and some of the app updates have even included bugs that caused excessive battery drain. This was seen just last week with the Weather Channel app where an update was found to cause significant battery drain, and that one has already been fixed by the developer with another update.
Yep, you have 3 of the top ten apps that are draining your battery:

The apps noted with Background Activity and Background Location are using your battery even when you are not using the app. For your Social Media apps, your battery is being used to build your Social Graph that is based on many factors including Shares, Likes, Posts, Contacts, and even the same data from other users you have interacted with. Your phone is also using much more Cellular/Wifi power to transmit this data back and forth to the developers servers. Of course, the apps are free for you to use, but their substantial revenue comes from this data they have gathered on you to sell to advertisers.
Take Instagram for example and look on the Privacy Page in the App Store where they must disclose the information they are gathering.
Yes, that is quite a list. Multiply the power required by 3 for those apps you see there and it is clear you are needing to charge your phone frequently. Each users Social Graph is much different which is why you see different battery usage across users and it depends on how much data they have to work with. I suspect you are a heavy user of Social Media and are quite active with friends, posts, likes, and shares and content. Even if you do not physically like/share a post, you are still contributing to your Social Graph simply by watching a TikTok or viewing an Instagram post.
As for what you can do about it, the truth is there is not much without deleting the app. The developer can certainly reduce the apps battery usage, but there is no incentive for them to do that as you are not paying them for using their service, but you do pay them with your data. Apple can show you the apps that are using your battery, so you can make an informed decision. Beyond that the apps are not violating any of the Submission Guidelines where they could pull the app, and I suspect you could imagine the uproar by users if they did do that.
