Sorry, there's literally NOTHING wrong with your phone. Battery Health declines normally with every full cycle battery charge and you seem to be upset to have lost 2% in battery health in at least 4 months, when the average loss is 1% per month. You can call it rubbish, but it's physics and there's one thing which is certain. The battery health on your iPhone will continue to decline and at some point it will dip to 80% at which time it will time to pay Apple to replace the battery in your iPhone. Worrying about something which is normal and can't be stopped is a waste of time and emotion.

No two phones can be compared to each other, as no two people use their phones in the exact same manner. And while iPhone batteries are rated at a certain mAh, some phones have more charge out of the box in excess of the stated mAh, which means they may not lose any health immediately, they WILL lose health ultimately. Battery health decline is NOT linear either. Meaning the battery can remain steady, then drop a couple points all at once.

The point though is you don't have a battery issue with your phone. There is NOTHING wrong with the battery in your phone and it is operating to spec. So worrying about it is pointless.
