Battery health

ive just bought my iPhone for just 1 week and my battery health have dropped to 98 in just a short time. The first 4 days it dropped to 99 and it just dropped to 98 earlier. Im scared. I charge it when it reach 40 % and unplug it when it’s 90 % or higher. What should I do

That can happen. There can be a variation in new battery capacity, and that might take a week to sort out.


Regardless of all that, Apple will only consider a warranty replacement if it's gone under the nominal rating for 80% battery health after less than 500 complete charge-discharge cycles. Anything in between is just considered normal variation until it gets to that point.
