How To Guide How to limit charging on Pixel 6

[boe323]

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

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.

With credit to VR-25 from Github:

If you edit these files and put you own values in then your phone will start charging when it drops below 75% and stop when it gets to 80%. (put your own values in, etc.)

I have only tested it briefly but it seems to work for AC and USB charging for me so far. No other apps or tweaks needed.

Hi can you explane how to modify the file and where it is located ? i can not fint this folder you mention it look like a text that is in the text file

If you can't see those folders and files then you are not rooted.
What are you using to view the folders, and are you already rooted?

No i am not can you send me a link or a guied to root it ? thanks

Hello, I read mixed success on making acca idle mode work on pixel 6pro. For those who were successful could you please share your success story?

Thanks!

This is working exactly as expected. I set the pause at 79, which allows the Pixel 6 to stop at 80. Sometimes it trickles to 81, but all's well. The idle mode is working. I can leave the phone plugged in forever and it will maintain its charge. Aside from not being able to unplug and plug it back in to maintain the charge further, it's working as expected. I am happy.

Android 12 was fine. Now, Android 13 is working fine as well.

ACC version is 2022.2.22.1. I am using the charging switch of "gcpm/constant_charge_current_max 1866420 0 --"

Idle while keeping it plugged in after a charge works perfectly. Upper and lower percentage configuration works as expected. I'm not touching it.

ACCA wasn't working for me (Android 12, Pixel 6, Build: SQ3A.220705.001.B2), the charging limits were ignored, and the daemon kept stopping every few seconds.

I installed above package through Magisk (didn't reboot, console said wasn't required), and now ACCA app/ACC package is working fine

I was running fine on the final release of Android 12 using gcpm/constant_charge_current_max 3160000 0 with the latest stable ACC (2022.6.4) and AccA. I lost root with a failed update to Magisk Manager and begrudgingly updated to A13 TQ1A.230205.002. Now the old charging switch won't work (although testing says it works) and none of the switches in the AccA list do either. Automatic works but doesn't idle.

Does anyone have a functioning setup on the latest A13 version?

Edit: A few hours later and everything including idle is working with gcpm/constant_charge_current_max 3160000 0. I didn't change any settings, install/uninstall anything or reboot. No idea what was going on there.

I'm still using "gcpm/constant_charge_current_max 1866420 0 --" with success, mostly. ACC version is 2022.2.22.1.. I've found recently that some lower charging currents end up a couple percentages over or under the upper limit. I'll try yours too, shortly.

Hi It's working in lastest stock rom A13?

Yeah, I'm only rooted with Magisk.

I have installed with Magisk ACC 2022.2.22.1 and got the latest ACCA 1.0.35 GUI app. The idle doesn't work for me, it switches just on and off the charging. Is it still working for you ?

Yes. Albeit less accurate than before, but still working. I find the battery charging to 82%, on most power supplies, when set at 79%. Otherwise, it does idle just fine.

Can you share your exact setup? I'm doing something wrong and can't figure out what.. It doesn't idle for me, it discharges as quickly as without charger plugged in.

I'm adding your charging switch to the default profile. Upon adding it asks me for ON and OFF value, I leave them blank. It should be using the default values of 70 and 80 in the capacity control, I guess ? Also the capacity control by default has value of 5% to Shutdown if not charging. Then I turn ON "Prioritize battery Idle mode". Don't touch anything else.
The only other thing that is ON by default is the temperature control with values 40deg 45deg and 90sec.
Actually I did play with different settings and switches before with no success, this is my 3rd or 4th fresh installation

Looked at this over the past few days. I had my Pixel 6 plugged in over the weekend. Unfortunately, earlier this afternoon I found the battery up at 89%. It appears to be slowly trickle charging past the set limit. Upon visual inspection, I saw the typical +2ma / -2ma kind of activity, which led me to believe it was working as intended. I don't often idle my phone for days at a time, but this weekend I did. I am back to the drawing board for a charging switch that works 100%.

I wish ACC was able to idle no matter the charge. For instance, if I was between the low and high values, it would idle immediately aftrer being plugged in. It would only charge if it was lower than the bottom setting. I used to have another module that worked this way, but unfortunately it didn't translate from my old Note 4 to th Pixel 6 well.

I'll be sure to post what I figure out, if anything.
