Possible positive? If it keeps it in the 20-70% range I'm told we are supposed to keep our devices in.
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.
Fundamentally, wireless charging is less efficient. Theoretically you could be putting 16w of heat into the phone but only getting 8w of charging.
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.
