Wireless charging is terribly inefficient. Unless your house is powered by your own personal off-grid solar array I really wish people wouldn't use it.
It's convenient AF, sure but it's the type of thing that's "meh" when only a few people use it but a bigger problem when millions adopt. Like K-cups.
- leetcrew 6y agothe transmission loss itself really doesn't matter on the scale of a phone or tablet. we're talking about less than 10 Wh wasted per full charge (assuming a 40 Wh battery, much larger than we see in phones). this adds up to a large number when you multiply across millions of iOS users, but it could be totally offset if each of them chose a single LED indoor light to run for one hour less each day. a more compelling argument might come from the battery degradation angle. wireless charging accelerates battery wear, leading to a battery or entire device being replaced prematurely.
