You’re right that batteries can’t be both in a “charging” and “discharging” state at the same time. However, a workload drawing 1 A from a battery and a charger supplying 2 A leads to net gain of 1 A, aka “charging”.
It isn’t both charging and discharging, it’s just in a state of charging, despite the workload it’s performing. Likewise, the battery can provide 2 A while only being charged 1 A, leading to a state of discharging.
So, a battery can totally power a device while simultaneously being charged, which I believe is how iPhones currently operate. The battery is always in the power path. Willing to be wrong, that’s just my current understanding.
I’ve been using AlDente for awhile:
Good feature set, some cool visualizations of charging activity (as cool as watts going into a battery can be…). Been very happy with it so far, keep my laptop at 80% pretty much all the time (mostly docked).
Absolutely! I welcome it in any case due to using MagSafe stands throughout the day.
The charitable thinking was that it’s only on the new models because they actually modified the power delivery circuitry to allow bypassing the battery for power. As in, a reasonable hardware limitation that prevents any older models from doing it.
The less charitable thinking is that it’s arbitrary software lock, which is unfortunately not entirely out of character for the Apple either 😅.
Alternatively, this just means it will keep draining/charging to keep it at a steady 80%, with the battery still fully involved with providing power to the phone.
All of the iPhone 15 and iPhone 15 Pro models feature a new battery health setting that prevents the devices from charging beyond 80% at all times...
I limit my laptop battery charge to 80% with a third party software tool. Laptops can generally bypass the battery and directly power themselves from the wall.
Does this new 80% battery limit setting imply that the new iPhones are able to do the same? Implication would be less battery wear while docked on a desk/in a car or due to long “AAA” gaming sessions, since it will draw power direct from the wall rather than using the battery as a middleman.
It works fairly well. A "daily driver" if you don't mind tinkering. Installed some basic dev tools, runtimes, and container workloads. You'll miss some QOL and efficiencies compared to macOS, and I couldn't quite get the trackpad to feel as good, but that's pretty par-for-the-course when it comes to running a non-macOS OS on a MacBook.
Since dual-boot is the default install option, doesn't hurt to carve other some space for Asahi and give it a whirl. You're intended to be able to use both on the same system as needed.
