Apple Intelligence is now available on iPhone, iPad, and Mac!
Hello. This is very strange. Two iPhone devices, first of them is older than the other, but its battery health is better:
Usage condition of right-hand device is much more moderate than the one on left, but its battery health percentage is less :(
Batteries do vary with manufacturer but in any case 95.5%, although disappointing, is not inconsistent with a 5 month old phone and would not be a warranty case unless it got to 79% inside the 12 months (standard limited warranty).
The value in Settings, Battery would be taken as the correct measure by Apple.

Mine is Sunwoda. Still on 100% from May activation.
The RH battery seems to not have fared as well as the left one, but it is still within the expectations, and in case you wondered, not yet a warranty claim item.
And with EVERY full cycle battery charge, Battery Health will continue to decline. It's what batteries do. ALL Batteries.
You need to stop obsessing over a measurement which is guaranteed to decline.
And you can say with 100% confidence, both phones have been used identically in terms of hours of use and battery charges? Batteries are not exact. And no two batteries will decline exactly the same. But the Battery Health measurement on iPhone is based on full cycle battery charges. It's highly unlikely the two phones have been used the exact same amount of time and undergone the exact same amount of full cycle battery charges.
I honestly wish Apple had NEVER brought Battery Health monitoring to iPhone. People are obsessing over it needlessly. Every phone you've ever owned had battery health decline. You just never had the ability to check it. You also never really worried about it. Now you do and it's pointless. If your battery declines below 80% in the first 12 months, you have an issue and Apple will replace the battery under warranty. Since it's virtually impossible for that to happen on your phones, just stop worrying about. Your phone will actually tell you when it's time to replace the battery.
I have no idea who CoconutGrove is, but I would only go by what my phone told me its battery health is. Why are you even putting any faith in a 3rd party service?
You don't have an issue with your phones. You're worrying over nothing. And there is nothing we as users on this user to user only forum can do for you and Apple won't either, because your batteries are operating within design parameters and expectations.
My final comment on this. You can reply again, but there's nothing more that needs to be said.
Forgot to mention that both iPhone devices were bought at the same day (3 July 2021).
Interesting but doesn't change my response.
Does the Battery Info tab give the battery manufacturer? Are they the same?
Yes. Both - Sunwoda.
Today it is 95%, while it was 96% (in iOS Settings' Battery section) yesterday.
I totally understand that. But having two identical iPhone devices one of them degrades faster despite the fact that it has been used carefully.
Sure they both were used differently. The left one was heavily used.
Battery degrading fast on iPhone 12 Pro. Faulty battery?
