I bought my iPhone 14 Pro last Nov and the battery still has a max capacity of 100%. This seems almost impossible considering I use my phone every day (moderate use) and charge it every day. If I had to guess, I used the phone 50% every day for 9 months (meaning it probably charged 50% for the past 9 months).

Is this a glitch with the iOS software or is it possible my battery really has 100% max capacity? I remember my iPhone SE dropping to 91% after a year.

I would say don't question it, just go with it and be happy its still at 100% and not jinx yourself. Next thing you know it's going to start dropping every few weeks. LOL

You may have been lucky and got a battery with higher than factory spec capacity.

Same here, iP 14 PM since last week of September.
Sunwoda - 207 full cycles - 4368 mAh (as per 3uTools).
As a side note, coincidence or not, after updating to 16.6 the max capacity has started degrading at a fast pace (3 weeks ago it was around 4430 mAh).
iOS still shows 100% as max capacity, though.

I am at 96% battery health on my launch day iPhone 14 pro max. Not too bad and I’m not worried as I will be upgrading to the iPhone 15 pro max. I usually charge overnight usually the supplied cable and using a standard iPhone plug from years ago.

Batteries are not an exact science. Some come over provisioned from the factory. Matthew.H is right.

My iPhone 14 Pro Max has 103.7% capacity after 5 months of ownership. Some come above, some come below, some come direct at 100%.

Have to use an app like coconutBattery to see actual capacity (or read it in the phone internals).

I have an 8 month old regular 13 with 100% battery health which has been charged wirelessly every single night.

It’s realistically around 95% with Apple’s inaccurate software giving a higher reading.

I can't remember when I posted it [I posted it here in MacRumors but cannot remember which thread] but an iPhone remaining on 100% for several months does happen...

I have checked my diagnostic data on my iPhone 7 Plus back then and based on Wikipedia, it has 2900mAh battery but I saw on the log that it has about 3000+ so that is why you see battery health showing as 100% even after many months have passed...

You can also check via Coconut Battery if you are using a macOS device as to what is the current capacity of the battery of your iPhone... On the link below is how you can check the diagnostic data and look for battery cycle and current actual mAh of your phone battery...

You have nearly ideal use conditions. Se battery degrades faster because small batteries are very bad: se1, se2, 12mini, 13mini of mine would drop battery health just by looking at them before 12 month.

Wife’s pro maxes were always traded in with 98-100%. The only ugly duck is 14pm: lives only 9-10hrs and battery sits at 89%.
