iPhone XR Battery remains at the same percentage for extended period of time after unplugging from charger. Is this normal?

I have been experiences this for a while now on my XR and i cant seem to get a straight answer. If i charge my phone and remove it from the charger at say 80% (happens at any percentage it is unplugged at) it will stay at 80 for a lot longer than any other percentage (similar to what happens when you unplug at 100%). . Once it drops down 1 percent it starts to operate normal again. BUT if i restart the phone immediately after unplugging the battery jumps up a couple of percent.

Basically the battery is more full than it shows and doesnt go down until it lines up with the percentage shown, and the only way to show the real percentage is to restart it

A few people on another forum said this was normal but the apple genius' i spoke wit yesterday said it was not. Very confused by this I have heard a number of contradicting ideas
 
The battery percentage does stay longer from when you take it off the charger. Having said that, you could try calibrating the battery meter by completely draining the battery and then charging back to 100% without any interruptions. But as long as it doesn’t turn off before it reaches 1% you got nothing to worry about.
 
It's been designed to do that intentionally so people don't freak out when unplugging the cable.
As the battery ages, the battery % indicator becomes less and less accurate. Sometimes mine will suddenly show 20% lower, then when I plug it in, it immediately jumps 10% higher the moment the cable is inserted. It does this more when it's cold than warm.

Apple does this on purpose with all their iPhones and Macs. If you plug in the phone to a Mac and open Coconut battery, you will see the actual battery %. Usually it's somewhere between 100% and 97% before the battery % will drop on the phone.

Android phones don't do this so it doesn't take long before the % drops to 99. I've left my iPhone at home and after 12 hrs, it still shows 100% and that is not possible. It's just the OS doing what Apple designed to do.

With modern iPhones/iPads, when they drop to 93.8 to 94% in reality, iOS drops to 99%.

Earlier it used to be 95% in reality.

Correct. The only people who have zero credibility are Apple employees. Not that they’re not helpful. But most are clueless about tech.
 
Here's an example:
I fully charged my iPhone to 100% and left it plugged in for 2 hours after it initially hit 100% (which I only do maybe twice a year to calibrate the indicator) and I used it right afterwards continuously.
I unplugged it at 8:30 AM and the battery indicator stayed at 100% for 3h 45m before it finally began to budge. Obviously that's impossible.

Consumers need to realize that an Apple genius is just a job title and they aren't overly qualified in most situations. They are positive salespeople who are there to sell a product with a smile on their face. They don't know what this forum is or even what a jailbreak is in most instances.

Some might be like that, while plenty of others aren't.
