My 12 mini is at 88% after one year. One of the reasons I ordered 13 and not mini. I don’t want to fear about battery and it’s health after such a short time.
Got a tip for us?

iPhone 12 Are you experiencing an abnormal drop in battery health on your iPhone 12/iPhone 12 pro/ iPhone 12 mini/ iPhone 12 Max?

Eh, I like the phone a lot otherwise. Battery life or longevity is not enough of a reason for me to use a larger phone that fits badly in my hand. The battery can be replaced pretty cheaply when it needs to be.
Also, from what I understand the 13 Mini has much improved battery life. When I've made the requisite 12 payments under the upgrade program thing, I'll just jump up to the 13 Mini.
I’m happy for you. I like it a lot mostly for one hand use and pocketability but as it gets hot quickly, not good for me for two hands writing (I realized that I’m making a lot more typos then I did on XS) and it’s battery life, it ruined my day much more often than I was willing to be OK with. I even got AC+ for it so maybe replacing battery wouldn’t hurt me that much. Now I’m looking forward to great battery but at the same time, I’m kinda worrying about that size. I’m little bit undecided from the time Apple went for 5,4 and 6,1” variations. I really would be happy with 5,8” screen in new flat design. Sadly there is no longer an option like that.
I think the iPhone 12 series in general have crappy batteries. In the family we have iPhone 12 mini, 12, and 12 pro, and all are at >90% after less than a year of use, which wasn’t the case with any previous generations with the same kind of use and charging habits.
This has to be an intentional change on apple's part, compare it to the battery in older iPhones and even iPads.
Are you sure this will not occur on the 13 as well?
- remember the ONLY differences is: Battery Capacity & Screen size. The cpu in the mini will get more throttling as heat under long intensive loads occurs, like any other phone just slightly more pronounced in the mini. the CPU/GPU is the exact same.
Update. Today I updated both phones from iOS 14 to 15. After the update the battery health on my phone dropped from 92% to 90% and on my wife's phone it went up from 96% to 97%.
I’m still hanging in there at 89%. I have monthly AppleCare+, so I’ll just have the battery changed out before I upgrade to the 14 Pro Max next year and keep the 12 Pro Max as a backup phone.
I don't know if I agree about the comments saying the 12 had a bad battery. Here is my 12 Pro Max when I traded it in (I shouldn't have) for a 13 PM:
120 cycles, 103.1% capacity - it held that the entire year I had it. Yeah I'm not a heavy user.
My wife's 12 PM did take a big dive tho...
But she was a heavy user of MagSafe and that thing got REALLY hot. <shrug>.
We always get the same phone and the 12 is the first time her health varied significantly from mine (usually within a few % points).
Both of our 13 PMs are holding at around 102.5%

My 12 Pro Max held up very well, the numbers looked very similar to yours until September. I wasn't concerned since it seemed to good, but it dropped down to 94% very sharply in a short period
Moreover, what other company even has a place for customers to check their battery health?
I might be wrong , but by reading this thread I’ve come to the slight conclusion that the battery cells being used lately aren’t as good as what was used for past iPhones. That coupled with fast charging perhaps.

As I saw multiple reports, many said that heat problems from 12 mini (or 12 series) is way less noticeable on 13 series. I don’t know it for sure.
103.1% capacity ... how does that even make any sense? How can you over charge the maximum capacity of a battery that will hold it and not explode, catch fire, etc. ??
91% health on 12 mini from February 2021.
393 charge cycles - so the drop is actually proportional to the number of cycles, reflecting that I have to charge the phone 2-3 times a day.
What is interesting is that iMazing reports the health at 95% - so battery probably started out at >100%.

It just means that the original battery capacity was in excess of design capacity.
Mine is getting worse by the day. 12PM and today it was fully charged 6 hours ago, I’ve had 3 hours screen time and I’m on 20%. It’s got to the stage where I can’t go out for a few hours without taking a charge pack. It’s just over a year old, health is 92%. Yet yesterday stats show less than 100% usage for 8 hrs. Makes no sense. Charging a small amount throughout the day massively manipulates the battery usage stats which isn’t helpful. Presumably apple will tell
Me to get lost if I complain? And say there’s nothing wrong with it.

Seems like a bad battery. Because 12 mini has (for me) in average 3-4 hours of usage. ??
Seems to be. Apple support did online diagnostics and apparently it’s all fine. Nonsense I said so have a Genius Bar appointment tomorrow. They’ll tell me it’s fine at which point I’ll push back and say “no no, it isn’t, and it’s a £1.1k phone so please sort it out”!
@BigDO is correct. It means that the battery came slightly over design capacity from factory. Batteries are not an exact 100%. Some have a slight % over or under the designed capacity. You can use tools like coconutBattery or iMazing to find out your battery’s capacity. I’ve had phones from Apple have 96% of design capacity (4% less capacity than they should). So 103.1% just means 3.1% over designed capacity.
The phone handles all the charging management and will ask what it wants from the wall - slowing way down after 80% charge to single digit wattages after 90%. All this can be observed via coconutBattery or a killawatt device. This is why charging from 20-80 is fast but it slows down after.
That is also why some phones will stay at 100% battery health longer than others. Because they came over provisioned from the factory while others may be under.
Possibly a silly question but want to check before making a fool of myself in the apple store tomorrow!
Using ball park figures but assuming average on screen time of 10 hours for a full charge at 100% capacity, can I assume that the equivalent for 90% capacity would be around 9 hours. Is that roughly how it works? If so, mine is currently operating at what should be 50% capacity as opposed to the advertised 92% on battery health (ie. At its peak the battery gave me 8-9 hours at 100% but now gives me 4-4.5 at an alleged capacity of 92%)
