I. About Battery Health Percentage:
Q1. "I have iPhone 12 Pro Max and its battery health drain fast even I used it very carefully not charger up to 85% and not less then 25% even then why it’s battery health drain fast it’s drain 4% in two month ."
A1. Apple recommends you get a new battery, once the Battery Health reaches 80% or lower. When the Battery Health is 80% or lower, it is time for a new battery. Unfortunately, these if no way to know how, nor when, then percentage decrease occurred. So, get a new battery if this is the case.

A2. Troubleshooting iPhone Battery Draining:
A. Battery Drain Info:
The iPhone battery will drain, unless it is plugged in and charging. With lots installed, the charge would be slower. As for how fast it would drain the battery, that would depend on the battery health and the volume (sound) you use.
