... should I be concerned?

Hello everyone,

I bought my iPhone 15 Pro blue titanium back in late January.

Six months after I bought it, I started seeing the battery health drop to 99%. That was on April 29th, and as of today, it's 97%.

I kept a charge limit of 90% for a few weeks, thanks to some other iPhone 15 Pro/16 users who gave me advice in the iOS 18 battery thread.

I'm wondering if it's due to how often I charge it. I understand heavy users get hit with this a lot, and I do use a certified MagSafe charger (Courant) for two weeks and it probably impacted the degradation. I charge it 2x/day including overnight, after a workout, during my break at school, and when I'm hanging in my room at home.

Your opinions are appreciated. I will continue to investigate this further. If I'm still doing the right thing to safeguard the longevity of this iPhone 15 Pro battery and it is not due to a beta or something I can do to help minimize it, I may also chat with an Apple Genius on my next Apple Store visit. It's completely abnormal for an iPhone battery to get lower health in six months.

For reference, my AW6, which is a year old, has only degraded to 91% battery health despite watchOS 11 betas misreading the battery health earlier on.

My 15 PM was activated last July first.

And it’s at 91% battery health - I think I am in a much more worse position than you with 97% battery health…

Still wondering the same thing, what I am doing wrong?

It degraded from 95% to 91% in roughly one month!

My 15 pro was off the charger since I woke up at 5:45 am and right now during my lunch at 11:02am it is at 37%.

Planning to use my new Courant MagSafe charger when I have a chance to sit at my desk during my lunch. And then put on a MagSafe charger on the back of my iPhone when I attend a lunch event and into my afternoon class.

Got it thanks for the link to a 16PM user who managed to have 200+ cycles and stay on 100% capacity. Will give it a good read later today

Should have held it on 90% charge limit since the start as I am a heavy user, and will try out the advanced search in the forums.

I am also a regular participant of the popular iOS 18 battery thread, just had seen a trend in battery health declining differently than my other iPhones did in the past.
