Battery health dropping 3% in 2 weeks

Battery Health decline is not linear, meaning it can remain steady for a while, then drop a few points. Typically, you can expect to lose 1% per month. What you failed to tell us is what the current battery health is and how many months you've owned your iPhone. One thing you can count on is for your battery health to continue to decline. Batteries are consumable parts and with every full cycle charge, battery health declines. This is normal, expected and can't be stopped. I find it difficult to believe battery health is a major factor in resale value. ALL cell phone batteries lose battery health naturally. It can't be stopped.

Today is exact 1 year I have been using this phone.

Since it is normal for the battery to lose about 1% a month, your phone should be at about 90% after a year.

So far, you are very lucky, but I think that you will see that the battery will start to decline at a faster rate at this point to catch up with the averages over time.

Try turning off Background App Refresh (Settings-General) and Precise Location under Screen Time-Content and Restrictions-Location Services-System Services-Significant Locations.

There are YouTube videos that cover what settings to change to preserve battery life.

"Battery health dropping 3% in 2 weeks: my iPhone battery health dropped 3% in 2 weeks. Even though, I always charge it 20-80%, with a 20W apple charger in cold environment. I do not have severe usage nor do I play games on my iPhone. This is alarming since iPhone resale value is dependent on battery health in my country. Please help"

All is fine. Unfortunately, there is no way to determine why, nor when, the Battery Health decreases. Once the Battery Heath reaches 80% or lower, Apple recommends you get a new battery.

yeah but the issue is we have no Official Apple Stores here and so its very difficult finding Official Batteries and/or other spare parts

I am also facing such problem. On June 1st, my phone had 97% but today(June 11) it is 96%. I charge once a day or sometimes once every other day. Today is exact 1 year I have been using this phone.
