Same charger and charging pattern here (although I try to charge it before it hits 20%), and my 12 mini is still at 100%

Launch day 12pm - Maximum capacity I just looked and is at 98%. The 8+ I traded up from was at 84%, so I was surprised it's already down 2%. I usually charge via a 20 watt charger w/lightening, I've charged wirelessly only a few times. But I've been trying to keep my battery between 80 - 20% ( charging when it hits 20%, disconnecting as soon as I notice it's past 80% ), maybe that's why my maximum capacity is at 98% and not lower compared to other folks. Glad I've got AppleCare
My launch day 12 Pro Max is at 97%. I have a 30W brick from Verizon, that I have yet to use. I use the 5W charging brick from my previous iPhones. I charge once my device reach 20% and charge overnight. I too up for 20 minutes when I get off work and charge overnight. I also heavily use my phone everyday, so I don’t see a problem being at 97%.
I have fast charged my iPhones with USB-C PD to lightning since the XS Max days and it never got this bad
Do prove your statement please. I’ve solely used the Apple 20W charger since November and my battery is still at 100%. And I’m a heavy user.
To be fair we also need to take into consideration that the battery health percentage calculation and display have changed multiple times from the XS Max ios days. I remember being long time at 100% and then sudden drop to 90%.
They change it every time in new ios updates.
My wife has a $10 case from Amazon and its' rubber is detaching from the buttons while showing the plastic underneath. This was the case with iphone's warm up during the fast 20W charge. I am sure that at least heat has its' effect on the battery health all else equal.
I remember there was an article on MR that they actually had to lower some of the battery quality of the 12 models to make up the cost of 5g modems. perhaps this is why we are experience this drop.
My iPhone 12 Pro started dropping from 100% in March or May, and every week or two or three it started dropping a percentage. It started slowing down but now it dropped another percentage a week ago.
88%
My previous iPhones were always charging, always using the fastest cable chargers, and always charging on my wireless charger (especially at night time) and charging with CarPlay. And never has it dropped farther than 97% by the time I get a new iPhone. I’m more used to seeing it at 99%.

You have to keep in mind that the way of displaying those percentages have also changed. Mine was also a long time at near 100% every time and then sudden drop. Because probably iphone was taking the mean/median value of the last 6 month observations or so.
Right now, it is still lagged version but not too far away.
In the dynamics, i would have more trust in coconut battery readings history rather than comparison of battery health percentages in different ios versions among different Iphone models.
If you were to have Coconut Battery history for all of them, then the outcome would be more precise, since the coconut takes the current/immediate readings, while ios battery health is just averaged number based on n amount of previous month readings.
Coconut readings are a lot more worse than the battery health. Doesn’t matter really, my battery life is trash even before the beta now.
It doesn’t get that hot, just a bit warmer. I doubt the slight increase in heat would damage the battery (or a rubber case for that matter). There are many apps and games which make the phone way hotter than using the official 20W fast charger. I’m talking wired (USB-C to Lightning), not MagSafe of course.

My iPhone 12 Pro Max and my wife's 12 Pro are both experiencing faster than normal maximum capacity degradation. I'm at 91% with my early December 12 Pro Max and my wife is at at 90% with her launch 12 Pro. We remained at 100% until May recently, and they've been in freefall ever since.
My then 12 month old XS Max had 97% capacity and my then 13-14 month old 11 Pro Max had 96% capacity when they were sold on. Both charged primarily with a 5 watt wireless charger.
Neither of our usage patterns have changed. Both of us are light to medium users. We top up our phones periodically during the day with 5 watt wireless chargers, and use optimised battery charging overnight also on 5 watt wireless chargers. Exactly the same as our previous wireless charging capable iPhones.

Very interesting article. Ouch!

European consumer groups demand Apple explain iOS 14 battery drain | AppleInsider
Members of the Euroconsumers Group have sent a letter to Apple asking it to address allegations of excessive iPhone battery drain in iOS 14.5 and later software updates.
Glad to be one of the few lucky ones with lottery battery ticket. I was able to still eek out a lot of battery life yesterday and still have 100% health on my launch date 12PM
Well your posts about your iPhone 12 lasting 10-12 hours before even reaching 20% without have to recharge is misleading, when you are constantly micro charging it.
My launch day 12 Pro Max is now at 96%. I’m not worried. I have AppleCare, so when I need a battery changed, I’ll just go to Apple.
Compared to the iPhone XR the battery performance really is poor.
Yesterday forgot to charge my phone 12 pro left the house at 11am with approx 50% thought that should do until I get back in the house.
Had a couple of beers in town , sat surfing on my phone by 14.30 was in low power mode down to about 15%, just seems pretty fast to drain, my XR seemed to go on forever.

Using iPhone 12 Pro Max since December last year and battery health just drop to 91%, been in contact with apple and the best that they can offer is an out of warranty replacement and to submit a feedback for the product, which I did and currently am escalating this situation.
Launch day 12 pro is at 92% while my launch day iPhone X is still showing 100%. Usage patterns aren’t that different and rarely go below 50% charge and slow charge (7.5w) overnight. The X is running 14.1, so will upgrade iOS once it has charged to see if the issue is software related problem.
Here’s the Battery Health for the 3 iPhones in the family:
iPhone XS (oct2018) - 88%
iPhone 11 (aug2019) - 80%
iPhone 12 Pro (nov2020) - 87%
I have AppleCare+ (on 11 and 12pro) so I’m not going to freak out over it. But still… battery degredation of 3yr old XS is same as 8 month old 12?!?!

Just finished upgrading iPhone X to 14.7.1, so the same as 12 pro, and battery health still 100% on the X compared to 92% on the 12pro, so doesn’t look software related. Also checked the battery cycle count which is 157 for the X and 100 for the 12pro (forgot that the screen failed on original X so was replaced under warranty, hence why cycle count isn’t that much higher for the X). Considering both where charged with the same Belkin wireless 7.5w charger overnight and never fast charged, it does look there’s a degredation problem with my iPhone 12 battery and, based on survey results and comments, quite a few people other people too.
