iPhone 13 Pro Max Don’t reboot/restart your iPhone 13 pro max, I REPEAT don’t reboot it

You don't. It's normal.
I just checked my old iPhone 8 on iOS 15. 78% reported, 75% with Coconut. Rebooted, 77% reported, 73% with Coconut.
Checked my 13 Pro. 56% reported 53% Coconut. Rebooted, 54% reported 52% Coconut.
If you don't have more than 5% drops when rebooting everything is fine, the more you obsess over this the worse your mental health will be.
Well, the system has access to the raw battery data, if they wish to change how the percentage is reported currently they can do so easily. It's not a "fix", more like a different philosophy. We don't work as computers. For example the 100% charge should only last a fraction of a second, right? It's like that. But we wouldn't like it. We like to be lied a little by the system. Let's keep that 100% for a little more. Same as with a countdown, it should start right away with the lower number. But we "like" to see the starting number for a while. Also the way music is randomly played is not really random, because experiments showed that true randomness doesn't appear as random to our brains. There are a lot of this mental stuff choices embedded in the products we use, because our brain doesn't really like some aspects of reality, so these little tricks are necessary. Quite fascinating topic, I read many articles about this.
You're right, but one thing is that they “lie to us” and quite another that after a restart our battery runs out by 5%. 1-2% is worth… but 5%? !!!
I agree, it could be less. I'm all for raw battery indication. Anyway it also depends on the time you do it. The nearer to a reboot or recharge, the bigger the difference. Try rebooting two times. The first time it will drop 5%, the second maybe 1 or 2% only. After many hours I observed the difference to lessen. Quick graph to explain myself, blue line is raw battery charge, red line is how iOS shows it to us, it lies more in the beginning (of a recharge, or of a reboot) then slowly reduce this lie:

Yes, the more times you do it, the less is the difference. The first 5% and the second 2-3%. Although it also depends on the time that passes between reboots. The more time passes the lower. In one thing you are wrong, it goes down the closer it is to 100%. In my case if it is at 20-30% it does not usually go down more than 2% but if I do it with 80% it can go down to even 75%
One more question. Do you know if restarting the iPhone many times can harm the battery or the device?
maybe you are right, maybe it's related to the total battery charge
In my opinion not. It's a little cpu intensive but no more than a game or any other taxing task, it's also quite fast
I enjoyed our discussion about the auto brightness settings and how to calibrate it when you have manually changed it. I was on another thread and found this youtube video on the brightness of the 12 ProMax and Pro compared to the 13 ProMax and Pro. Very interesting and further enlightening my knowledge about this setting and its use
This is a good point. If the phone was just intentionally misreporting its percentage, then it should continue at the value it was after rebooting, minus some charge spent on rebooting. But it seems that it's losing a few percent at a time when rebooting, suggesting that the battery percentage is stuck.
Update - turning off OBC is not needed to get rid of the symptoms temporarily. Just a charge to 100% will do. My battery percentage also started dropping after the battery was stuck, suggesting that this might be an initial calibration issue. I'd definitely like to hear an analysis and recommendations from Apple engineers as this problem is not as simple as we all think it to be.
Oops, accidentally quoted myself and edited the quote instead of editing the comment :<
It is a simple topic of battery calibration and% calculation at the software level. The problem is that these first versions of iOS 15 bring so many bugs that Apple engineers have too much work ... Let's hope they solve it soon! Or they will have to give us all a new iPhone…!
Still no tech site speaking about it, disgusting really.
setup auto brightness correctly last night, not enjoying it so far, very dim for my liking, lets see how long I last.
Yes now not sure I like the dimmer display in darker/gray areas Like in car today grey and rainy. All this made me realize I usually end up on all my phones with this feature upping the brightness bar. Yeah I know that reduces battery charge on a day to day basis but we shall see
OT: Does anyone have any older iPhone to check the sharpness of the 13P 1x camera? As per this thread by me https://forums.macrumors.com/thread...ftness-less-sharp-than-older-iphones.2315872/
This softness of the camera bothers me more than the battery, especially visible on text close-is, but it's visible in many other instances. I'm not alone in this so I think all can be like these (but as with the battery, few notice)

My display looks fine. Right now the display brightness is 32% for me. What is your current display brightness?
Most of time now calibrated my display looks good. But in some situations like in car on a grey rainy day it dims a bit for my liking.
Cloudy and grey rainy day in car in my case. Most areas good. I wonder setting it to minimum in dark to calibrate has it darker on grey cloudy days with light filtered through car window while waiting for wife to shop
