What is ideal battery health for iPhone 15 after 6 months of usage?

This is normal battery performance.

good thing its just 99% for 5months mine is just 2 months become 98% im not often using it while charging. now 8months become 91%

I’m from Italy and I have an iPhone 15plus, battery production august 2023, bought september 2023, today 10 october 2024 with 270 recharging cycle.

20 september 2024 the battery was 100%, today is 95%. Going down 1% every week. 😕

apple notifications recently notified me that my battery was most optimized at 80ish percent so it stopped charging pass this threshold. Additionally I'm only charging on Mag because new 15 purchase came with defect Cport. My battery typically last 16 hours but I've noticed a drain hugely when synced to other devices such as MacBook. The question will be a question asked for decades to come if Apple exists due to the fact that sync, API's , WiFi , Bluetooth aka iOT exist creating a network for juicing off your device.

You’re conflating the battery health percentage discussed in this thread with optimized charging and the battery charge percentage.

For your case, Apple regulates the battery charging, seeking to reduce the time the iPhone is fully charged.

In addition to other potential power consumption causes, if you’re running iOS 18 on an iPhone 15 Pro or iPhone 15 Pro Max, or on any iPhone 16, Apple Intelligent can consume a fair amount of power.

But all of this is independent of the battery health percentage discussed in this thread.

Consider whether you bought a battery to monitor, or an iPhone to use.

All batteries can and do inevitably and inexorably degrade.

Yes, most batteries don’t have an estimate of battery health.

When a device battery no longer meets your needs, the battery gets replaced.

Vehicle batteries, for indtance, are routinely replaced after some years of use.

If your iPhone is meeting your needs, then the battery is fine.

Some of the best advice I've read about batteries.

As per the discussion, I might have a magical iphone 15 because I’m using it since four and a half month(exact 136 days) and done 157 cycle count while sometimes I was using it with charging on also and still my battery health is 100%.

Your welcome.

bro my battery already 97%. I just used it for 2 months bro

My iPhone 15 Pro battery health is at 88% after 8 months is that normal? I charge my phone sometimes three times a day maybe 4 I don't really keep count anymore. Is anyone else having this issue?

The answer has already been given.

I am using 15 Pro. It's been only 7 months and it's already 88% battery health and here some people are worrying about just a 2-3% drop. 😂
