iPhone 16 Pro battery health dropping rapidly in three weeks

Battery Health goes in one direction only and that is down. Your battery is performing exactly is should after 207 cycles. On average, for every 50 cycles, you can expect about a 1% drop. 207/50 = 4.14. Your current battery health is 96%. You've lost 4%, which is exactly where one could expect it to be. Please note that battery health decline is not linear, meaning it can remain steady for a while, then drop a few points all at once.

So yes, what you're seeing is completely normal.

Read this support article about iPhone battery and performance to learn about the battery health feature and what is considered normal performance --> iPhone battery and performance - Apple Support

To see the feature go to: Settings > Battery > Battery Health

"A normal battery is designed to retain up to 80% of its original capacity at 500 complete charge cycles when operating under normal conditions. The one-year warranty includes service coverage for a defective battery. If it is out of warranty, Apple offers battery service for a charge." A degraded battery may display the notice: "Your battery’s health is significantly degraded. An Apple Authorized Service Provider can replace the battery to restore full performance and capacity." If it is not at or above 80% "normal", consider contacting Apple about a battery replacement. --> iPhone Battery Replacement - Apple Support

According to the above quoted information, you could be losing almost 2% per month the entire first year before Apple would deem this to merit a warranty replacement.

Yes, your battery is right on schedule. Some months it might decline 1-2%, then not decline at all for the next 2-3 months. This is normal. The following are general guidelines:

At 250 Charge Cycles, the battery will be at about 95%

At 500 Charge Cycles, the battery will be at about 90%

At 750 Charge Cycles, the battery will be at about 85%

You get the idea. There is no need to babysit the battery and check on the settings all the time. It will just make you nervous. Replace the battery when it is at 80%.

Thank you

Did you read what I wrote? I thought I was pretty clear in explaining that yes, it is normal.
