Hows your device in what way? Battery health?
I got my iPhone 15 pro in January of 2024 and with 172 cycles it’s still 100% health. I haven’t had it long enough for it to really even drop a percentage unless I was abusing it.
That would be my guess. Personally I just plug my phone in and charge to 100%, albeit with a slow charger. I also abuse the battery by using my phone for navigation, so it’ll often be hooked up to a charger in the car. My Samsung A52 lost a whopping 3% battery capacity in 3.5 years.
Charging to 80% would often not be enough to last the day, especially if I had to charge it before hitting 20%, so I’m perfectly fine with losing a percent capacity per year. By the time the battery starts to become noticeably bad my phone will be out of software support anyway.
