Plugged-in phones should use power directly instead of passing through and degrading the battery.
They do, energy can't pass through a battery on the way to powering something. It just skips the battery and directly powers the device.

Re: How to prolong lithium based batteries
#92I have had my phone for 4.5 years. I charge it every night to 80% - I have Accubattery installed, so it pings to tell me to unplug it, and it also does a fairly decent job of measuring the capacity. I charge on a fast charger (10W) instead of the super-fast charger (18W) because that keeps the temperature from rising too much. I use the phone a fair amount, so I'm usually charging from around 50%. Therefore, the batt…

Just as a PSA, you can create an Automation in the built-in Shortcuts App to do something similar.
(Show Notification / Speak Text on Battery Level below 20% / above 80% - enable Automation, and turn off Ask Before Running and Notify When Run)

#93Two unconventional things I do to improve my iPhone's battery health (which follow this article's findings): 1) Don't use a case - Otherwise, you are literally wrapping your phone in a rubber insulator 24/7, increasing its overall temperature. 2) Don't charge at night - Turn off your phone at night. Instead, charge it during the day when you're at your desk. This reduces the number of cycles over years (because your…
Can’t use the battery if the device is shattered. No case is not an option for my clumsy self.
Turning off my phone at night is not an option. I want to be contactable in case of emergencies.

#94I’m not a battery expert but some coworkers from the battery lab at work are, and they say that charging more often is better than doing big cycles. On most chemistries. In more concrete terms, it’s better to keep the state of charge between for example 60 to 30% compared to for example 80% to 15%. Big cycles like 100% to 5% are the most damaging over time.
That defeats the point of having a big battery. You're sacificing battery life to gain battery longevity

Do you know if it is true that a battery reporting 100% is really only 80% and 0% is really about 20%? I heard that somewhere, but have had trouble confirming it. At least for something like a common smartphone.

iOS will not fully charge your battery during the night - it will top off the battery just before you usually take it off the charger in the morning (it learns your usual schedule + it probably also makes sure the battery is ready based on your alarm settings).
In the US there's also an iOS charging option that considers the local grids carbon intensity.

#97Earlier quoted context omitted.
I wish more devices offered a way to enable a “slow charge” mode. When I’m plugging my laptop into my dock to work for the next 8 hours it doesn’t need fast charging. When I’m plugging my phone in before bed to charge for the next 8 hours it doesn’t need fast charging.
As others have mentioned, many phones do this in software, but I find the easiest solution is simply to use a charger incapable of fast charging.
It's harder to do with a usb-c charger and laptop because the spec requires higher voltages are made available with higher wattages, and manufacturers only make products to hit sweet spots in the specs and market.
You might end up with a readily available 65W charger to get the necessary 20V, even if you don't want 3A.

i have 2 chargers near my bed, one has 3 amps, the other one has 1. i use one on another depending on how fast i need it charged. not the best solution, but it works.
I have a wireless charging cradle on my nightstand intentionally hooked to a slow charger. It works fine most of the time except on the rare occasion when the phone charge is low and I'm going somewhere in a couple of hours. It would be great if there was a charging cradle with a simple "fast/slow" charge switch.
Or even better, if phones had a built-in charge status UI that instead of just saying "NN% charged / TT minutes until full" had a slider controlling charge speed that showed a range of "time until full". That way users could intelligently choose the charge speed vs time based on context.

#99I've been using ACCA[0] to set limits on battery charging on Android devices for years. Note that it requires root. ACCA can limit charge percentage, allowing the device to operate plugged in without charging beyond a certain point. It can also pause charging when the temperature exceeds a threshold, limit the charge rate, and several other tweaks to charging behavior. By default, I use a charge limit of 60% and a ch…
This sounds great and is exactly why having root is valuable. Unfortunately, I've given up having root because the cat-and-mouse of staying ahead of manufacturers updates became too burdensome and I wasn't willing to constrain my phone choices to only device with accessible root.

Accubattery is an android app, so that wouldnt help much.
