This is all anecdotal, so take it as you will. At some point in the past I used to be careful to do 80–20, or even 70–30 when possible. It was usually a pain, because I didn't get the full benefit of the battery, and I was always worried I might go above or below my targets. I still had to replace a battery after 2 years.
Then, with my previous phone, I decided not to worry about that and just charge whenever. The vast majority of the time I charged to 100% using fast charge, albeit not overnight. I had that phone for 4 years and it was only in the last year that I felt the battery had got worse. That last year was also after a big software update.
With my current phone, I'm doing 80–20 again—but more often 85–35—without fast charging. A year and half in and the battery has definitely degraded. I have easy access to a charger most of the time, and I use a software feature on the phone to limit charging to 85%, so my current schedule is easy to keep to, but if it wasn't, it probably wouldn't be worth it for me. I'd just accept that, worst case, I have to buy a $50 battery every couple of years to not have to worry about charge levels.
I wish it was as easy as just buy $50 battery. But with a waterproof phone I don't think waterproofing will be ip68 when I replace the battery and being able to just dunk my phone in water or run it under the sink when it's Dirty is so freaking easy. I do find it kinda weird that you doing 80-20 made the battery worse I think it might be just newer battery tech/software but you saying that your new phone also has the battery degrade faster than your previous phone makes me wonder if maybe manufacturers are already doing 80-20 in the software maybe and mapping 80 to 100 and 20 to 0. And that charging it more often is worse than just doing 100% and charging it less. I think I am definitely going to need to setup some experiment to figure it out. And maybe going to ask honor for advice. Thank you for sharing this information.
I would take the parent poster's experience as definitely anecdotal/coincidental. A lot of factors can cause a battery to degrade faster, beyond just faster charging or doing full charge cycles. For instance, simply using the wrong kind of case (say, something like a heavy-duty Otterbox case) could cause heat to build up and reduce battery health. It could even be caused by a cheap or non-compliant USB cable..
If you want some real battery facts, check out the Battery University, it should have all the info you're after.
https://batteryuniversity.com/article/bu-808-how-to-prolong-lithium-based-batteries has a table explaining exactly what I wanted to know 10% discharge depth results in a larger total charge the battery can carry throughout its live than a 80% for example
