Hey, i have 13 PRO MAX. I bought it on June 2022 and now it is March 2023. It is been 9 months. My battery percentage has dropped to 96% and is rapidly decreasing. Is it normal that even before a year i’ve dropped 4 percentage of 13 PRO MAX?? Please i want to know i am worried. I even use my phone with full care maintaining it’s battery cycle and everything. Thankyou

Batteries are consumables and they degrade over time with usage due to chemical aging, that's just how they work.
You can expect about a 1% drop per month with average use on an iPhone.
Apple recommends replacing it when it reaches 80%. To check your battery health, go to Settings > Battery > Battery Health.

4% drop in health is 9 months is better than normal. It's fine. Keep up the good work.
Even if it is 13 PRO MAX ?
Yes, Lithium ion is Lithium ion whether it is in an iphone 6 or a 13 Pro Max
