I've used my old phone for a good six years. I've swapped its battery some three years ago, and it would've needed a new one now, had I continued using it.
If that phone is any indication, my current one should be in service for at least as long. If I can avoid having to swap its battery, it's a win in my book.
It can also sometimes happen that I foresee being away from an outlet or otherwise need as much charge as possible. In those situations, I'd just deactivate the battery saver feature and let it charge to 100%. So if the remaining capacity is closer to its original one, again, it's a win.
If you don't charge fully until just before the user's normal wakeup time you aren't keeping it all the way full all the time.
You protect the battery lifespan and get a full charge at the beginning of the day, instead of having a battery that constantly holds less charge.
You keep repeating this and seem to ignore my observation that if the battery isn't drained below 80% when I plug it in, it will recharge it fully immediately. It will not wait until the user's wake-up time.
And in my case, it's rare that the battery falls below 80%, so whenever I plug it in, it gets recharged fully right away.
So, in practice, it's all the way full all the time.
Yet year after year, surveys show that more battery life is the feature people want in a phone the most.

Intentionally throttling the battery's ability to charge no matter what is going the wrong way.
