Most high-quality LiPo-powered devices already do this at the hardware-level. The 100% level you see on the software is usually 80% actual charge on the battery.
For Android, there are a multitude of apps, such as Wattz that will tell you the actual voltage of the battery. Full may be 4.2V or 4.35V depending on the chemistry used. ACCA (root required) will let you limit charge rates and stop charging at a certain percentage.
Staying under 4 volts (around 60% for most phone batteries) will vastly extend battery service life. 80% is a bit less extension, but still far better than charging to 100%.
Unless it’s lying about the voltage itself, you can be pretty sure it’s not limited if it charges to 4.35V. 4.2 is a little more tricky if you don’t know for sure whether 4.2 is the full voltage for the cell.
Not sure how accurate this would be as charging is not 100% efficient. Also the amount of power the phone uses while charging would have to be taken into account as well.
Isn’t the charge limit of the battery arbitrary? The manufacturer can set whatever target voltage they want , so it’s meaningless to say they limit the battery to 80% when they decide what 100% is.

Any way to tell? I just got a monster phone with a 22K mAh battery.

i was looking for something like acca since forever
foss discoverability needs some mad work
that doesn’t answer the question of whether there’s a way to tell that their battery is limited to 80% on hardware level, though.

omg kilo milliampere
k = 10^3 and m = 10^-3 so they will cancel out. It’s just Ah without any prefixes at that point.
Charge it from a smart power supply from battery at 1 to 100% then it can show you the number of mah/h it took to charge it.
I have this power supply which also has USB-C https://a.aliexpress.com/_mrChiQ6

My phone has a 10.8Ah battery and it’s huge, no idea how big that must be.
mAh are a terrible way to measure capacity, look for watt-hours instead. You need to know the voltage for it to be a relevant measurement
So can I charge my phone to 11?
It’s one more than ten, so yeah, it’s better.
Yea that’s what I’ve heard, and I personally keep stuff plugged in
It was a recent article by iFixit, so I thought I’d share it ¯\_(ツ)_/¯
80% “software” should keep the battery even healthier…

Yes
Do you have sources?
