100% for me, first month or two I used the fast charger and more recently I've used the 40-80% method.

I’m still at 100% - launch day 12 Pro Max.
Lately, with more Zoom calls, I tend to go 1 1/2 to 2 days before needing a charge.

So many variables can affect your battery health Everything from heat to cold to how you use your iPhone to whether or not you fully discharge it to how often you charge you iphone each day.
accessories that are used with your iPhone also affects battery health.
Poor signal strength causing your iPhone to constantly search for signal which eventually effects battery health
The list is long

Launch day 12PM at 100%. Charge it via the 20W apple USB-C Adapter if I'm in a hurry but usually MagSafe Duo every night. I use it heavily I'd say, depleting to 20% usually every day. I use my phone how I need to, don't worry about the battery health, there's enough worries in life "LOL".
This is extremely technical, but it may make sense perhaps.
Since I don't have "share with Apple" turned on in my Privacy settings, I don't have this detailed "log-aggregated" file available right now. I would be very curious to see the true stats of my battery.

I don't know, but it's aggravating. I'm TRYING not to let it deflate me...
Some have 100% still, some down to 95, 94...few low 90s??
I saw ios 14.5 will "recalibrate" the 11 iphone Battery Health numbers, if by surprise it helps 12 users, hope that helps...maybe? Right now, I can't figure out how many have the no "health loss." (Unless they did get a 105%-107% true battery life from the get go)
Others like us are losing 1% - 2% + per month - because we perhaps got a true 100% battery. I don't know...all guessing at these random numbers.
I've read multiple posts not just here, but Reddit, other forums. We're not alone w/ the erratic numbers.
Again not to beat a dead horse. I don't charge overnight and not understanding why one night I'll lose 0% battery, 3-4% on most nights, but Sat night into yesterday morning..same time frames of 6-7 hours, I lost 11%. No change in background app use, nothing showing why its draining more.
This is the way phones operate? I'm religious with my battery monitoring. I have excel documents with thousands of rows of documented battery capacity and health estimations etc. From one day to the next, my battery does not act consistently... why? Because the OS isn't consistent. Some days I'll run different applications, some apps will receive data I didn't on the previous day. One cannot expect consistent battery behavior with application variables today.
I don't think Apple's battery health is random. I've been watching battery capacity since my 6+ with 3rd party tools that read Apple's own data. It's NEVER exact. If I do a reading at 60% battery, it's going to have very different results than at 100%. I only read capacity when fully charged because it can vary quite a bit when not fully charged.
If anything, I'd trust Apple's battery health far more than anything else ... they're the ones that designed the hardware and the software.
People act all crazy about batteries yet don't understand simple basics. Batteries come from the factory with a wild varying of capacities. Some 96% of design capacity, some 108% of design capacity. That's how some phones are still 100% design capacity after years of use and others fall to 90% after a few years. Of all the iPhones I've ever had, they've varied WILDLY on the capacity from factory at 0 cycles.
Apple really should have left the Battery Health hidden...
Thank you! i posted something like this before when people talk about battery health.
Why? They won't do anything with it as long as it is >80%. If it is >80% it's performing normally. They won't even let you replace the battery if you show them $ unless you get a really sympathetic genius who is really nice. (I've tried before - store policy is usually <80% before they'll even consider it).
You have a $1,000 minimum phone.…a new battery from Apple costs $69 installed.
This is the tech equivalent of a Maserati owner complaining about needing to buy another set of tires after driving.
My phone came with a battery at 102% and a maximum battery capacity of 2941.
Release day iPhone 12 PRO
It's the only phone I have and I use it daily. I do partial charges multiple times a day but I only use the 5W charger (exclusively)
Current cycle count is 151 and battery capacity is still at 100%.
Applying 25% - 85% SOC rule since day 1....
