Wireless charging should be regulated. It’s a wasteful joke that burns more carbon by wasting electricity
The amount of electricity used to charge phones is statistical dust. If you want to save electricity there are 1000 better places to worry about.
Yep, definitely. A bigger problem is the additional heat generated, especially if the phone is also being used at the same time.
Multiplying every phone in use by the average capacity loss at 50% that’s the best case scenario for loss ( ignoring the newer phones using significantly more power and glass to insulate). You do not have a statistically dust number of wasted carbon every day.
Let's say everyone in the world has a smartphone and charges it 100% every day. Let's say that it's 4000 mah battery so they waste 2000 mah. This is very very generous. That's 7.4 wh per person per day X 8b people X 365 days a year = 2.1x10^13 wh. In 2022 we used 1.7x10^17. Or 0.01% Like I said, statistical dust.
The energy consumption of replacing a worn out cable is pretty bad too.
The energy consumption of replacing a whole phone when the port wears out is considerably worse.
Oh and as a bonus, the wireless charger provides unbeatable isolation from lightning strikes or a defective power brick shorting to mains. I can't say how many phones are saved that way, but it's also something of an energy savings.
Delusion is strong in this one.
“Worn out cable…. Ect ect fallacy about power loss.”
Nice straw man argument, you are really reaching. Not only will it never happen to get close to the wireless waste but we are talking about Brand new future device.
I abuse my charging port with headphones, 5 years not replaced. This still would not come close to the loss.
it’s at least 50% power loss over wireless. At minimum.

I'm not talking about "resistance change in a cord blah blah". I'm talking about the power and resources to manufacture and ship a new phone, after your old phone fails prematurely. The kilowatt-hours being poured into a phone's battery over its service life are a miniscule part of its TCO. Doubling that makes it two pittances.
