Is there a way to slow down these high power chargers? Sometimes I want a fast charge but mostly I want slow to getting hot. I realize overnight charging phones are smart enough to do this but otherwise seems to be impossible without having two different chargers.

#63I wonder what temperature this thing hits. I have an even smaller 65 W GAN charger[0] that gets pretty toasty under load. I can't really see Apple wanting to ship a toasty charger, though. [0]: https://rollingsquare.com/products/supertiny-the-smallest-65...

My current thinking is that the phone shouldn’t negotiate a higher wattage than it wants. Hypothetically, you could bolt it to a 1000W charger, and if it only asks for 30W, that’s all it’ll get.
The concern isn't that a 9000W charger will fry a phone expecting 30W, it's that charging at 30W subjects the phone/battery to more stress/wear than charging at 5W.

#66How does one distinguish between all the tiny devils in the details between all possible chargers to have the maximum efficiency in ones iPhone charging?
There really aren’t any nuances to be aware of here. If the charger can provide 45W or more, it will charge your iPhone 17 Pro as fast as it can go. If you have an older iPhone, you don’t even need that much. The Apple charger is mildly interesting because they made a slightly smaller than usual one that displays a dynamic behavior where it boosts up to 60W. That’s it. (If you actually mean efficiency of energy deliv…

#68Why do so many websites disable pinch-to-zoom for mobile users? This page is full of interesting close-up photos, but at least on my Android phone, I can't zoom in to see any of the details. Who benefits from disabling this feature?

#69At my work, we have an X-ray machine for PCB reverse engineering. On Fridays we throw in random stuff from around the office, and sometimes make videos about what we find inside.
A few weeks ago we released an X-ray teardown of several other, older chargers. Very interesting to compare with these fancy new ones!

What is the logic or science behind that claim? I’ve fast charged my iPhone 16 pro (heavy user) daily if not more often for a year using Apple chargers with the charge limit set to 80%. Remaining battery capacity is still 100%, which is something I’ve never had after a whole year. Fast charge doesn’t seem to hurt.
