There is absolutely nothing wrong with your battery.
Batteries degrade over time with usage due to chemical aging, that's just how they work.
You can expect about a 1% drop per month with average use on an iPhone.
Apple recommends replacing it when it reaches 80%.

Rohn ~ Again, unless you have other information, your iPhone 11 could have been in a supplier's warehouse for 3 years – so its current 93% max capacity is healthy and there's no issue to fix. ...Enjoy your iPhone 11!

That is no concern at all. Your battery is fine, until your Battery Health is at or below 80%.

Okay, good. But, unless you have other information, your iPhone 11 could have been in a supplier's warehouse for 3 years – so don't assume it's "brand new". And its current 94% max capacity is healthy – which is what matters. ...Enjoy your iPhone 11!

There isn't really a "normal". But rest assured, your battery is fine, until your Battery Health is at or below 80%.

Rohn ~ How do you know? ...Perhaps it was in a supplier's warehouse for 3 years. Did you buy that iPhone 11 from a reputable source such that the battery would be genuine and show a correct max capacity %?...

No, I don't think it's a software bug. You perhaps have a 3 year-old battery which is indicating a healthy 94% max capacity.
