Had my phone for 1.5 months now if I remember correctly and it was 100% capacity and checked today and was 99%. It wont make much difference but already moving down. Anyone else??

If it goes 80% or under during warranty period Apple will replace it. Other than that, nothing you can do unless you want to start minimizing battery usage and change your charging habits
Yeah and it is not a big deal with the max or really any phone now. Just was wondering if anyone else saw the same drop.
 
Lol, my 12 Pro Max is exactly 364 days old today, and its at 80% battery health with 345 cycles, and Apple says its 'in good condition'. They won't replace it unless its at 79%.

They used cheap quality batteries in the 12 series, people just upgraded rather than complain, Apple figured out another way to skimp on costs. Seems like they did the same on the 13 series. Now this will be the norm, with batteries needing to be replace once a year. Ridiculous.
 
Do you wirelessly charge or use the MagSafe charger? That’s probably why.
I've had my 13 Pro since release day, so almost 3 months. Have run the battery below 10% multiple times, charge it to 100% overnight on a MagSafe charger every single night. Battery capacity is still at 100%.

The battery capacity in iOS is a rough estimation. 99% could still be 99.9%. 100% could really be 104% or it could really be 97%. Either way it doesn't matter - if your phone drops below 80% within the warranty period, Apple will replace the battery for free. If it's outside the warranty period, pay to have a new battery put in. It's not worth obsessing over and micro-managing battery usage, IMO.

My 13 pro max was received on the Monday after Friday launch and it still shows 100%. I use the lightning cable with the older style 5w cube charger. I usually charge my iPhone every two days, otherwise overnight with optimized battery charging turned on.

Just checked mine. I’m at 99%.

I got my regular 13 Pro on 4th October which has been exclusively charged on my Samsung Wireless Charge Pad. Once a day to 100% charge with no babying.
 
Battery units are not exactly the same. Charging habits should affect their durability, but cannot affect the quality of the unit that your iPhone had come with to you. The same model of knives, cars, headphones etc should be identical, but it never happens. Best companies decrease differences between units and keep high average production level.
On the other hand it seems a kind of mystery how Apple's battery indicator gather data - or it is not?

It's just an estimate. I wouldn't worry about it. In fact, unless you start to actually notice a significant decline in battery life, I'd suggest that people not even look at their battery health for at least the first year! All it seems to do is cause people stress over very tiny declines.

And despite what many people will tell you, not much that you do in terms of charging, discharging, and using your device is likely to have a significant effect on your battery longevity, unless you're really abusing it by frequently exposing it to crazy temperature extremes.
 
I’m at one year one month on my iPhone 12 PM and the battery is at 97%. Almost made it to one year at 100% but that is a not true number.


If you get lucky and get a battery that has more charge than what Apples says - like 108 percent of what they claim - it will say 100% until the number drops below the stated capacity and then the number keeps going down. The luck of the draw but your battery capacity keeps dropping from day one.


Forget about it and just replace the battery when it’s no longer reliable. They (Apple) will crack your screen protector when you get it back, but once you get used to replacing the battery, you fret less about it as it’s not a life indicator for the phone as many people see it.


Forget about the number till you notice the drop in day to day usage. Then replace it.

I bought a new battery from the Apple Store for my Launch Day 12 Pro Max when it was at 89% capacity...it's sitting right beside my bed with 100% capacity right now. The store employees were actually surprised it degraded that fast in less than a year.

Too bad I don't use my 12 PM that much after deciding to get a 13 Pro Max.
 
Oh brother! No...so far mine still reads at 100%. (Coconut battery has shown a strange fluctuation..up and down since iOS 15.1 - 94% to 103.9%. *Right now 2 days after 15.2 install it went from 103.7% slow decline to 101.2%, kind of holding there right now...I dont know!? - maybe it recover again like it has been doing, no idea.)

...of course I know it's just a matter of time until I see that "99%" 😐 AND when it does, God I don't want the same issues as 12.

But my 12 Pro Max, bought day before T'Giving 2020...battery on that dropped to 99% just short of 2 months in mid Feb..(then a crazy 100% drain overnight for some unknown reason..Apple couldnt even explain it.) Since that,.. it dropped like a rock. Down to 87% by Summer. 83% when I traded that thing in...took advantage of the high value $.

My experience with Apple Support...so useless. C'mon...80% on 13 month old phone. THIS is just pathetic! Replace the battery!
 
I honestly think the battery health number is not exactly accurate but battery technology is complicated. I have always wondered if apple intentionally interferes with the reporting software to reduce warranty claims because it is evident that they purposefully use lower quality batteries.

But my 13PM is still at 100% battery health. 20W wired charging.

Ultimately I had to pay to get my battery replaced, and now there's a point on my phone where the color of the stainless steel was "rubbed" off thanks to the incision of whatever tool they use. Absolute bs service.
Do you think the store would have replaced the device if you had brought up the repair damage?
 
No chance, they’d just say it’s cospefyicnand is to be expected. This has happened before.
But it’s the technician that damaged the phone while repair in process? Wouldn’t they offer to replace the device? I sent it my macbook pro for a failed logic board. I sent it in for a repair, and it was in a pristine condition. No dents or scratches on the lid or anywhere to be seen.

After the repair was done, I went to pick it up, only to notice that on each corner on the lid had a chip mark/dent. I asked the genius bar tech that this was not how I sent my macbook pro in for repair, they looked at the documents and the previoius genius documented that the cosmetic was very clean. They agreed to replace the lid at no cost.

Same went for my wife’s phone when Apple offered the reduced rate battery replacement, got the battery replaced, but noticed that the screen had some dust/deadpixel inside the screen. I told them that it wasn’t there before the repair. So they replaced the screen at no cost either.

The difference is that you went to apple directly. In my country, apple service is only through authorized service providers, so they can get away with it. I did report the case to apple on the feedback mail that you get after service, but I doubt it’ll do any good.

I see. Thanks for clarifying
 
Thing I have noticed among many iPhone users is that when they send or post screenshots, then you can see that in many cases battery is almost depleted. I have asked some of such people, that I personally know, why they do it. They say they are conserving the battery by letting it completely discharge and then recharging it with slow, overnight charge.

So let's quote Luke Skywalker here... “Impressive — every word in that sentence was wrong.”

That all was true for NiMH batteries, which iPhone is NOT using. iPhone is using modern Lithium batteries. These are not even old Lithium-Ion batteries, the tech has evolved a lot in time.

First of all, Lithium batteries don't have memory effect what so ever. So completely discharging and then fully charging has no meaning at all.

Secondly, the perfect charge is between 50-80% in which the battery is in such chemical state that aging is the slowest. iPhones even have this optimized charging, when you leave it for overnight charge then it charges to 80% and then waits and charges to 100% by the time you usually start using it. Sitting behind your desk and charge has dropped to 49% and you have charger at you hand? Perfect, plug it in.

Thirdly, slow charge is not good for Lithium batteries. Charging stresses the battery chemically over the time it takes it to charge. Fast charge is not bad, high temperature is bad. The faster the charge, WITHOUT creating excess heat the better it is! But remember, Lithium battery is chemically more active, when the temperature is higher. So some heat is actually good, to the point, when it does start to degrade the battery. But don't worry, that point is not where you say "my phone is warm", it's the point where you would say "the phone is super hot, I can't hold it in my hand".

Urban legend: Is wireless charging bad?
No it is not. You have several circuits and controllers between the wireless charger and the battery. For the battery, the phone is the source of the charge current. The phone takes the power from cable or the wireless charger and converts and directs it to the battery.

Bad thing about wireless charging is that if you don't have matching size coils and/or they are not perfectly aligned, then it creates a lot of heat just next to the battery, which itself will heat during the charge. So let's scroll up a bit. Too much heat is bad. But here comes MagSafe. The coils match and magnets keep it perfectly alligned, so it doesn't generate basically no heat at all.

So I've been living according to these principles and the result?

1.5 years old iPhone 11, 100% battery health
0.75 years old iPhone 12 Pro Max, 100% battery health (it has been used with MagSafe all the time)
1.5 years old Apple Watch SE, 99% battery health (but consider it's a very small battery that will degrade much faster)

I mostly live by those principals and I have a 3 year old X with 444 cycles and 100% capacity per Coconut. It should be at the point where it needs to be replaced but isn't so I believe them to be accurate. Another guy here who does this showed his battery history and he had somewhere in the neighborhood of 1500 cycles on his phone and battery capacity was still well above 80%. I'm a light user and work from home with a charger in front of me all day. It takes zero effort to set it down to charge occasionally throughout the day and my battery is always around the 60-80% mark.
