How To Guide How to limit charging on Pixel 6

If you would have read the correct information on this subject. You would know that this not true for today's battery technology.
This is nothing but a myth.
You will have a better chance looking for Bigfoot.

Why waste 40% of your battery use....

the 20% is use li-ion batterys, dropping below 20% (if the battery is malfunctioning) can lead to swelling, but its best practice to charge your phone around 15/20%, the 80% thing is just a myth. storing li-ion batterys should be around 40/60% though

the 80% thing is just a myth

Do you have non-anecdotal evidence for this? All I've seen is evidence to the contrary...

1. the often quoted 'Battery University' data https://batteryuniversity.com/article/bu-808-how-to-prolong-lithium-based-batteries
2. various phone manufacturers slowly introducing various strategies to limit the time the battery spends above 80% e.g. https://support.google.com/pixelphone/answer/10011133?hl=en#zippy=,optimizing-for-battery-health-pixel-later,get-the-most-life-from-your-battery,charging-temporarily-limited-pixel-later

If fact I've NOT seen other than anecdotal evidence that discharging to below 20% before a recharge IS a problem! All I've read (sorry can't find a reference) is that the reason to keep the battery at 40% in storage is to stop it discharging too soon to the point where the battery's protection circuitry doesn't get power and stops the battery from charging at all. This is actually below the battery's 'indicated' 0%. And an indicated 0% still leaves enough charge in the battery not to damage it chemically.

Either way I would say don't obsess about it, but keeping the battery between 20 and 80% can only improve battery longevity whenever 60% of its capacity can get you through the day. This in my case is frequent given, like many, I now work from home. I will charge it up more when I know I'll be out for the day, though to be honest with in-car charging if I'm driving I find I'm often not using even 50% of the phone's battery capacity in a day... What have you got to lose by doing this anyway? All this just means I hope I won't need the hassle and expense of a battery replacement whilst I have the phone (3 yrs probably) and even then I will have nearer to 100% battery capacity on those occasions I actually need it.

Another interesting point is that (at least according to the Battery University page above) "The worst situation is keeping a fully charged battery at elevated temperatures."

That's exactly what happens when you use a phone for navigation attached to the windscreen in a car on a hot and sunny day and have it sitting, potentially for hours at a time, at 100% plugged into a car charger. And you'll probably get even more heat if you happen to be using a wireless charger :-( Another good reason to limit charge level and, perhaps, temporarily halt charging whilst the phone's temperature is too high. All sounds complicated, but if an app can automate it all...

there is an updated acc variant to try
https://github.com/VR-25/acc/releases/download/v2022.7.4-dev/acc_v2022.7.4-dev_202207040_1927.zip

post how it works for you

I have this working for me on a rooted P6 and it’s pretty easy to do. I just installed AccA from F-Droid. The ACC module in Magisk showed v2022.6.4 by VR25. In settings for AccA I clicked on ACC version and changed it from bundled to v2022.6.4. Rebooted and it’s working.

Hopefully that helps someone else struggling with it like I was. With the bundled version selected in AccA the Daemon would stop running but I haven’t had that happen yet with the version changed.
