To keep your battery fresh for as long as possible, always keep the phone connected to a charger. No battery cycles. It will get worse after a few years anyway.
This isn't really true, as far as I know. If you avoid fully charging or deeply discharging a lithium-ion battery, the wear per unit of energy extracted is smaller.
There are some statistics quoted here (https://batteryuniversity.com/learn/article/how_to_prolong_l...) showing that if you, say, halve the amount of energy you retrieve from a battery in each cycle, the battery lasts for more than twice as many cycles.
This paper arrives at a similar conclusion (see figure 4): https://www.researchgate.net/publication/318292540_Analysis_...
Also, I want to add that what I wrote above is only regarding smartphones. I don’t know how much stress/extra heat etc that EV batteries are subject to, but I imagine they drain/charge at more intense rates relatively.
I so wish manufacturers would offer this option, for those primarily deskbound who do not relish ungluing their battery after a year
Edit: they call it Qnovo Adaptive Charging and they get another minus from me [0] for making it impossible to select text on tye page by long-pressing it.
[0]: they got a huge minus from me back when they added "sponsored links" to my flagship Z3 or what it was.
Thanks for making me aware that such a thing exists.
Fundamentally, wireless charging is less efficient. Theoretically you could be putting 16w of heat into the phone but only getting 8w of charging.
