Wired chargers are 85%-90% efficient, Qi is somewhat between 75-85%. If you live in a country powered by green energy it shouldn’t be a concern :)

- Polylactic_acid 6y agoI'm going to guess that 15% missing on the wired is the brick itself. I'm not sure how 5% more losses can make my phone heat up quite hot and also charge very slow. Are you sure it isn't 15% lost at the brick powering the wireless charger and then another 20-25% on the charging pad itself?
- criddell 6y agoSo wireless results in about 10% efficiency loss? So if half of the iPhone 12 users adopt wireless charging that's about 36 billion charge cycles per year (100 million phones charged daily). Those are big numbers. It seems like it would add up.
