Hello~ First click on below and review…
If the battery in your iPhone drains too quickly - Apple Support
Second, I see you have an iPhone 12 listed correct? Did you have that battery changed and if so by whom? If that battery was replaced by someone other than Apple …that may be your issue. Post back?

What do you define "incredibly fast?" Your iPhone battery health is expected to drop about 1% a month, and the decline isn't always linear. Meaning some months you may not lose any battery health or other months more than expected.
What does "incredibly fast" mean? It is not unusual for Battery Health to decline very slowly over the first few years, then drop off as the battery runs out of steam.
The really important thing here is.......about how old is the phone?
What is the Maximum Capacity? Settings > Battery > Battery Health
