Phone battery health at 93% capacity and 396 cycles

To learn about maximizing (and the difference between) battery life and lifespan, read this support document --> https://www.apple.com/batteries/maximizing-performance/

Read this support article about iPhone battery and performance to learn about the battery health feature and what is considered normal performance --> https://support.apple.com/101575

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

iPhone batteries are designed to retain 80 percent of their original capacity when charged for a given number of complete charge cycles under ideal conditions.. See the article for exact details. 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 maximum capacity is not at or above 80%, consider contacting Apple about a battery replacement. --> https://support.apple.com/iphone/repair/battery-replacement

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

Don't obsess too much about the battery health feature. It's a general guideline to let you know when you may be nearing the time to think about replacing the battery, but nothing to lose sleep over.

That's pretty good, probably much better than typical. Apple judges that the battery needs replacement after it reaches 80% capacity, yours is only ~ 1/4 of the way to 80% but after 396 cycles and the battery is expected to last 1000 cycles. So your capacity is declining but slower than the number of charge cycles is approaching 1000. You are in good shape with your iPhone and its battery.

Update: I now see Linmos posted before I did, Linmos' response has many useful links and information for you.

Elsewhere it was stated:

Just remember to replace the battery when the Battery Health has dipped just under 80%.

A good idea (and what Apple recommends) but you don't even have to do it then. That's basically a level where you might find it annoying to have to charge your iPhone several times per day.

The battery in the iPhone 17 Pro was designed to go up to 1,000 Charge Cycles before the Battery Health / Maximum Capacity declines to 80%......under ideal conditions.

That works out to an average decline of about 1% for every 50 Charge Cycles.

So, your battery has completed 400 Charge Cycles. Doing the math, 400 divided by 50 equals 8%. So, ideally the battery, which started at 100% has declined 8% to 92% Maximum Capacity at this point.

Your battery is at 93%......better than expected. Maybe think about sending flowers to Apple.

Just remember to replace the battery when the Battery Health has dipped just under 80%.

You're in great shape as others are suggesting. Read this, which I wrote to help people better understand Battery Health Decline --> https://discussions.apple.com/docs/DOC-250012201
