Still 100%. I'd expect it to drop to around 95-97% after around 12 months. I am using my phone heavily working from home, so maybe my usual percentage drop will accelerate - who knows.
I have Apple Care+ anyway so I don't worry about these things.

Launch day 12 Pro max, still at 100%. Not a heavy user and only charge it till 80% then I take it off. I do have the Weebo plug that can have it scheduled when to turn on and off. I have set it to turn on every day at 5:30 am and by the time I wake up at 6 am, it's at 80%. When I go to bed it's usually sits around 60%.

I'm at 99%. I've had my 12 Pro since Nov. 3, 2020.
According to coconutBattery, it has 35 charge cycles.
I keep mine topped off during the day because I listen to a lot of podcasts, but I'm not doing any fast charging because the battery never reaches 80%. I do use MagSafe with the 20 watt charger.
If I lose 1% every three months, it would take the phone 5 years to reach 80% capacity.

Charging habit so far;
- iOS Battery Health: 100%
- Cycle Count: 101
- Coconut Battery Health: 100%
- Coconut Battery Design Capacity: 2815 mAh
- Coconut Battery Full Charge Capacity: 2887 mAh
Charging habit so far;
- Used 5W charger exclusively
- Never used fast charging or wireless charging of any kind (except one charge on magsafe but then immediately returned it)
- Kept charge levels between 25% - 85% religiously (I have a smart plug that stops charging when it reaches 85%. See my post HERE)

Nice breakdown, thanks! I find the Coconut Battery full charge capacity to fluctuate, at what charge % were you at when you read the 2887? Do you have any idea when it would be most accurate? I would think 100%, right?

This should be a sticky on this forum.

I was around 80 percent. Based on previous readings, it only fluctuates within only 5 mAh so not much difference I guess

The battery health on my iPhone 12 Pro dropped to 99% after only owning it for 3 months. This got me really upset (more than it should have) for the past few days. On my last iPhone, a XS Max, the battery health stayed at 100% for over a year.
Thinking it through, I think it's a combination of factors that has lead to the battery health on the 12 Pro dropping so fast:
1. This is a smaller phone than the XS Max, so it has only 2815 mAh battery versus 3174 mAh in the XS Max battery.
2. I have used the hotspot feature on the phone more frequently at my new address because my Comcast internet goes out so often here. Using a phone as a hotspot puts a lot of wear and tear on it and the battery because it heats up the phone.
3. I am using MagSafe wireless charging, which also heats up the phone more than the 7.5W Qi charging I was using before.
So, it still sucks, but it begins to make more sense. What comforts me is that I do have monthly AppleCare+, so if I keep the phone long term, I can get a battery replacement paid for by AppleCare+ at some point.

Not the Pro or Pro Max, but my 12 delivered late October is still sitting at 100% after moderate to heavy use most days. I do have optimized charging turned on and never top it up or let it drain fully so I think that’s been helping keeping it at 100% more than 5 months later.
now i see it

Rest assured that some employees are getting nailed by PWM flickering too.

never experienced anything like this before but my capacity is at 94% on my iPhone 12 Pro Max. Battery life sucks, my phone gets hot when doing simple tastes like texting - having the brightness at around 50% with auto brightness off. Every week since the last 3 weeks I’ve been losing a percent. Is this normal ?
I have AppleCare and I will take the phone into a store.
Coconut battery is telling me my cycle count is 120 cycles.

Yes get that phone replaced
What did you use to charge it and at what wattage?
Most of the time I charge it on my MacBook, or in my car on the usb.
I never let it go below 75 % .
I called Apple this afternoon they tested my phone and told me everything is normal , no hardware problem…
