If you're charging every night - you definitely have a crappy battery.
"Another angle to this story is the influence of the EU, which
requires customer-friendly battery replacement in some circumstances.
If the cell does not reach 83% of capacity after 500 full charges,
or 80% after 1,000 full charges, then the phone is required to have
greater access to make replacement easier. While all the latest
iPhone 15 models meet the 1,00-charge test, earlier phones do not."
The introduction of a new battery technology like this is a strong message
for Apple to stop putting the crappiest batteries they can into the iPhone.
But time will tell how Apple works on the problem that all iPhones have the crappiest batteries in the smartphone industry by a huge failure margin.
Why Apple puts the worst batteries in the industry in iPhones is up for conjecture (e.g., to shorten iPhone lifespan, for greater profits), etc.
The fact simply is that the iPhone has the crappiest batteries of all.
But maybe that will change with the iPhone 16... we'll have to wait.
*Apple To Upgrade iPhone 16

"The next iPhones, the iPhone 16 series, are expected to include
models with an all-new battery design, with battery life amplified
with a new, powerful processor. Everyone wants better battery life
as well as more power and there's also a suggestion we will be
able to hold on to our iPhones for longer."
"It's thought the new battery will be found in some iPhone 16 models,
though perhaps not all, with the expectation that all models in
the iPhone 17 range released in 2025 will see the new design."
But, unfortunately, instead of adding a better capacity battery, Apple apparently is opting merely to put the existing crappy battery into a metal case, according to the details which are published as recent rumors.
Still, given iPhones have the worst batteries in smartphones, it's a
welcome statement that the EU seems to have forced Apple's hand at
designing a produict that doesn't fail after only a couple years.
And, when the iPhone inevitably fails due to the crappy batteries Apple
puts in all of them, at least this will make it easier to replace.

BTW, I'm well aware that the ignorant religious zealots claim that a puny single-digit percentage in "efficiency" magically overcomes triple-digit percentages in smaller battery capacity - which is simply absurd.
