iPhone 8 Battery Drainage

I have an iPhone 8 and about 4 or 5 months ago the battery started draining really fast for no reason. And my battery health of my phone is at 83%. So I don’t understand why it would be draining so fast. And I have done tons of research and done what I can to fix it but it hasn’t really done anything. Anybody have an idea what the problem may be or how to fix it?

Check with the folks that work for Apple. 83% health with an iPhone that’s somewhere between a year and a half and four and a half years in age is seemingly getting low, particularly if the battery is “draining fast” and not holding a charge.
