[ROOT]Faster Wireless Charging using Automate

Untested on the Q Beta!
For information about the way the mod functions read this.
This mod is possibly dangerous given its nature of modifying the safeguards built into your phone by Google. I am not responsible for your actions using this mod. This mod is meant only for Pixel 3 and 3 XL devices, I would recommend against trying this on other devices.
All that being said I use this mod daily and decided to share. Attached is a ".flo" file used by the app "Automate," link to download from play store, to import the flowchart for the mod. The reason I used automate instead of the typical Advanced Charging Control Magisk module is due to the module having much more functionality that I didn't need or want. Examples include weird charging behavior with USB-PD chargers and overall charging instability. This also allows the mod to be disabled by booting in safe mode.
Details about the mod:
This mod may stop working after any android update
This mod seems to even allow non "fast charge" wireless chargers to be faster
This mod allows a max of 9v to be accepted through wireless charging instead of stock 5v without Google Certification.
This mod reverts whenever the phone stops charging (this is the part that this Automate Flow automates)
Details about the Flow:
This Flow requires 2 apps (Automate and Automate superuser permissions plugin) be installed from Google Play Store
This Flow requires superuser permission on the device (Magisk recommended)
This Flow does NOT modify /system
The file that is modified by the Flow is reset upon unplugging/lifting off a wireless charger so uninstalling Automate will undo the mod completely
The Flow runs like this:
Wait for wireless charging state to change
If wireless charging connected: run shell command then Go to 1
If wireless charging disconnected: Go to 1
So if the phone is not charging or cable charging there isn't an endless loop running.
Instructions:
Download and extract the .flo file
Download Automate app if you have not already
Open Automate app and go through its first time setup
Use the 3 dots menu in the top right to select "import"
Navigate to where you extracted the .flo file and select it
Select the new Flow that just appeared
Under Privileges check the checkbox "full (superuser) access..."
Google play store will prompt you to download the superuser permission app for automate
Grant superuser to automate
Press Start, you'll get a persistent notification about the flow running
OPTIONAL: Go back to Automate app's settings and check the "run on system startup" to enable the mod on boot
You can verify success based on the log in Automate or by observing the charging text on the lockscreen/ambient display. If it says "charging slowly" then the mod failed if it says "charging" then the mod succeeded. You can also check in apps such as Ampere, the charging current pre-mod for me was always <600ma and up to 1200ma after. Note after ~70% charge the Pixel 3(xl) seem to slow charging speed so have a <50% battery for a good comparison.
To uninstall the mod just uninstall Automate or open the Flow and then in the 3 dots menu press delete.
EDIT: Now available in Tasker flavor for those of you who use Tasker and don't want a second automation app running on your phone. Just open the .XML file and select open with in the top right and then Tasker on the pop-up.

@StykerB
Thanks for your work, but i use the App "Automagic" https://play.google.com/store/apps/details?id=ch.gridvision.ppam.androidautomagic
Attached is the flow for Automagic. Need also Root permissions.
Procedure:
1. wireless power connected
2. send command

I just installed this on my Pixel 3 XL and will try it out with my Choetech wireless car charger. Typically I was seeing < 500maH of current with this stock charger. I hope to see over 1A with this patch.
Thanks,

So we have finally found away around the google certified fast chargers?

Works great for me, Thanks.
Would be great to get the assistant features of the pixel stand working too.

I got 850mA when using this MOD and a Choetech wireless charger. Now I can top off my battery while streaming audio and running waze. Previously, I can only stay flat on my batter charge.
Well done!

I used the Automagic version. Worked good. Was seeing 500mA before then it bumped it up to 850mA - 1A range.

Thank you for this

Has anyone had an issue where it start charging and the 2 seconds later it stops and then starts again and keeps repeating?

I've noticed this behavior with one of my old nokia wireless chargers or if i have a charging speed reading app open while the battery is >70% (when the battery management locks charging speed to 7.5w or less). But for me it seems to either go away after a minute or two or re-situating the phone on the charger.

Works great with my Samsung fast wireless charger! Goes from 600 ma to 1000+

Hm I'm trying to understand the exact shell command that is sent as I use Macrodroid.
What is the exact command I should use?
Also does this method still work on Android 10?

Limit battery charge level with kernel

DISCLAIMER: I'm not responsible if your battery or phone ever borked due to you used the commands in this post!
Just found out that there's "parameter" in /sys for limiting battery charging behavior, which probably works just like "battery charge limit"
Obviously this requires root, if you have no idea what is this for and why, read this first
As I'm no pro here, I'm just sharing what I found out, and the method may not be 100% reliable as ACC (the Magisk module, which currently somehow doesn't want to work on my 4a 5G)
Note that the following commands may not work due to you're running different kernel
To make your phone stop charging after reaching 80%, run the following command:
# echo 80 > /sys/devices/platform/soc/soc:google,charger/charge_stop_level
You can use cat against /sys/devices/platform/soc/soc:google,charger/charge_disable to check if your phone had stopped charging.
There's charge_start_level as well, I guess that the phone will start charging again after your battery level drops to the level that this "parameter" specifies, but I don't really leave my phone plugged in that long so I'll leave that for you guys to test it.
PS. I don't know why but this method may only work once for one boot, in other words, you need to reboot the phone for this method to be effective when you charge again. Edit: it worked more than once for me now.

Many thanks. The battery on this phone is amazing. I would like it to last as long as possible.

Since it's been a few months since this phone is out; are there apps that can do this yet? I run CalyxOS and can't root. This feature is #1 on my wishlist for a CalyxOS update.

Thsi can be done with ACCA Magisk Module and there is even an app for it called AccA on github. You can set different profiles with the app.

AccA only works on the 4a 5G when using a custom kernel such as protonkernel or elementalx. The stock kernel doesn't have the right switches.

Confirmed working on Android 12PB2 thank you so much the AccA app is not working on my pixel 5 either appreciate your brain

On Pixel 4a 5g control file that works for me is sm7250_bms/charge disable and Automatically cycle through switches is ON. I've installed ACC through Termux from downloaded github zip, thren I've installed AccA from F-droid and disabled ACC module in Magisk. And it works, it stops charging, in my case, at 85 % .
Maybe it's worth to mention that I'm on LineageOS for microG 18.1, Proton kernel 1.4, Magisk rooted.

It is at different pass in my Pixel6a, but it works! (Android13 2022/11/5 updated)
echo 80 > /sys/devices/platform/google,charger/charge_stop_level
Thanks a lot!

There's actually just a parameter that needs to be enabled under vendor/etc/perf section.... I forget which one of the XML files it's in, but you'll see something along the lines of "support idle xxxxxx" I can't look at the moment but it's fairly obvious when you do see it. If I get some free time I'll dig back through there and find it

Question Automatic shutdown according to battery percentage app or Magisk module.

As the title says, is there any app or Magisk module that can automatically shutdown your device according to battery percentage?

ahhh we have almost the same issue but my issue is whenever my battery percentage reach 20% wifi get disconnected i need to to setting and wifi and click scan again for it to get reconnected i think it is some sort of battery saver
i hate it whenever i'm playing it disconnect me

Actually, I'm not asking about an issue.
I'm asking if anyone knows of an app or module for Magisk that can shutdown the device accordingly to battery percentage.
I'd really like to set my phone to shutdown when the battery hits 15%.

Macrodroid can (with root). It's like a simpler tasker app. I'll pm you my telegram link, i can send you a quick video if you like...?

I do at 20% although 30% or higher be better.
After 20% there's a lot less usable power available and charging from that low is more stressful on a Li especially if fast charging.

I'll do 20% shutdown and 90% battery charging stop.
That's 70% usable power, I can't do anything better than that.

I generally do 40 - 70% or so. On my device it's 3 hrs on SOT and take 15 minutes to fast charge.
Li's like frequent midrange power cycling; use it if it fits your needs.

Magisk module : Advanced Charging Controller (acc)
https://forum.xda-developers.com/t/advanced-charging-controller-acc.3668427/
It has features as:
Shutdown at set percentage, eg. 20%
Stop charging when reach a percentage, eg. 75%
Cool down charging, so the device and battery won't be very hot using temperature detect on battery.
Charging voltage/current limitation.
Charge cool down as set, eg. 50 seconds charge and 10 seconds cool down without charging, then repeat.
Read the README in github.
ACC app has some issues. Module is working better and updated.
The module will need you to manually edit the settings profile, and you need to use command line.
If you just want to stop charging at certain percentage, Battery Charge Limit is enough.

Both need root.

I use Battery Charge Limit already on my Mi Pad 4.
Advanced Charging Controller seems to have a lot more features.

I haven't been able to get ACC with ACCA (GUI) or Battery Charge Limit to work on the Poco F3 with Xiaomi.EU rom and root.
None of the control files work on both apps.

AccA is faulty.
Use the Magisk module.
You might want to ask cutsom ROM developers because they had managed to get smart charge working, so there's definitely control file that works.

I got Acc with AccA working!
I was testing the charging switches without plugging in the charger, my bads...
Some how Battery Charge Limit does not work, it's a simpler app and I used it with my Mi Pad 4 so I thought it would just work with the Poco F3.

Check ACC control config what control file your phone uses, then see in Battery Charge Limit if you can select that control file manually.
I think it can also manually write the control file, but not quite sure.

Yeah I figured that, but since I have Acc with AccA working there's really no need to go back to Battery Charge Limit.

Just to clear the things that you've already said
You mean ACC with AccA is working properly? If not, is there any problems with using ACC with AccA app?
I used ACC with AccA app before on my raphael times with EvoX Custom ROM, works well and haven't encountered any problems with using with ACC via AccA App

Themes / Apps / Mods [MOD/magisk/root] Set charging limit to 80/85/90/95% v2

After some readings on: https://forum.xda-developers.com/t/limit-charge.4355851/
and https://forum.xda-developers.com/t/mod-magisk-root-set-charging-limit-to-90.4363477/
( Credits to @rickysidhu_ and @foobar66 )
There is a thing I found and tested:
"charge_stop_level" must be used together with "charge_start_level"
Spoiler: Details
If set start @40 / stop @60, the phone will begin charging when (and only when) the battery drops to 40%, and stops charging @ 60%.
(it defines a range, and the first time the user hit the range boundary activates this range function)
If set stop @90 without setting a start, the phone will refuse the 2nd time charging until the battery drops to default 0 (or the battery service/phone has been restarted)
(This explained many "phone not charging" reports in the above links posts)
I like @foobar66's magisk mod solution. It is simple and safe.
It has only 1 line of working script in the zip.
So I "clone" it with some different values (added the fix, so 2 lines of script code in each zip now, that's all it does)
These are for the lazy people who don't want to deal with advanced settings, and who want a 10-second trouble-free simple solution for battery health.
The 4 clones:
P6n_charginglimit_95.zip (charging limit to 95%, it should give you an extra ~30% battery life span in lab-tested theory)
P6n_charginglimit_90.zip (charging to 90%, an extra ~60% battery life span)
P6n_charginglimit_85.zip (charging to 85%, double the battery life span, recommended for joe and johns)
P6n_charginglimit_80.zip (charging to 80%, should give more than double the battery life span)
Those numbers are the best estimates from other battery research papers, no guarantee.
To install, pick the one you want and flash it in Magisk.
To uninstall, simply disable or remove it in Magisk.
A12.1 tested. It should work on A13.
Edit: A13 is also confirmed working.
Reply problems if you find any.

I use advanced charging controller, I stop charging at 81% and I can regulate voltage as well. Temperature triggers etc it's great.

How does it increase battery life by 30%?
Or you mean battery health ?

I use ACC plus Tasker to keep the battery entering idle mode at around 50% while plugged. I got my pixel 6 last November, now the battery gets 82 cycles so far.

The thing is, ACC monitors/controls too many components in the system that I don't fully get, and I am not sure if it conflicts with built-in "smart charging" or other circuit controllers or not, and have to combine a Magisk backend module and a root-access frontend APP to make it work with so many details settings to setup....... It is just......too heavy?
(or I am too old to tinkering those things.....my sad middle-age life)
These .zips are the "10-second solution" for lazy folks.
It does only 1 thing, It is transparent and super snappy (only 2 lines of script, no binary), and it can hardly go wrong.....it just works.

Yes, this might be device dependent. It is better to choose and set proper charging switch which supports battery idle mode.

It doesn't interfere with the built in stuff and you don't need magisk module anymore. It takes 20.9mb on system so it's not heavy, I also like being able to adjust on the fly (have it set to 70% for long home use and 85% for out and about)

So when I setup acc stopping at 80% on Android 13 and its place on pixel stand 2, the charging oscillates on/off. It would charge for few minutes then stop and charge for few mins and stop. Are you experiencing this? This behavior did not occur with Android 12

Oh weird I get the osculation on car charger but it was always random. It won't even charge on 13.
Change the switch to 0 should have it working I don't know if that causes the switch enough

I strongly agree, just not worth having to deal with acc, getting idle mode to work, debugging, getting it to work again and hoping it still works. If I get the time to do so might write a module that integrates a slider in settings or as a quick setting to set to what percentage it should charge and executing those lines of code with that percentage.

Question [SOLVED] Wireless charging issue, is it me or A13 ?

Hello,
I was looking for a way to use Battery charg limit on my pixel 6 Pro, using a pixel stand 2. (because I'm using it a lot)
So when A13 came out, I rooted the phone, and started my research.
I found a message in a thread that specified a way to do what I want.
[APP][ROOT][4.0+]Battery Charge Limit v1.1.1​
jazic said:
I finally found the ability to 'pause' charging on the Pixel 5, 6 and maybe 6 Pro?
This work only with wireless charging but I'm sure the /dc/ folder for wired.
I use tasker to control the file:
/sys/class/power_supply/wireless/current_max
I did figure out how to have it always have the file set to rw with the profile itself by using "run shell" and enabling root:
chmod 0777 /sys/class/power_supply/wireless/current_max
Obviously you can set up a profile to control it with tasker but personally I have mine set to start charging full speed when the battery is 0 to 65% then start trickle charging half speed until it reaches 72%. Once it reaches 72% you can set the current level really low and it'll basically keep the charger cycling on and off at a very low input voltage so the battery will hang at whatever you set it at without dropping then charging back up all the time which imo is better than cycling power off at a certain level then charging back up.
I'm still experimenting with current levels but if you set it to higher than your charger can handle then it will just simply charge at max speed of your charger.
For trickle half speed charge I use: "500000" (500mA?)
For full speed charging I use: "2200000" (2200mA?)
For Battery Charge Limit I'm sure you can set the file to:
/sys/class/power_supply/wireless/current_max
Enable: 5000000
Disable: 1000
You will need to set the file as writeable maybe?
Any questions hit me up. Maybe it's another source to look for other phones.

Click to collapse
I was thinking it all worked but in fact not...
For me now, wireless charging is very buggy.
Using Amper, i'm often in "not charging" or I'm charging at 4V and max 600mA.
I don't know if it's my fault or if it's related to the bug with the Pixel 6 wireless charging issue ?
Also, can someone give me the default value of this file "/sys/class/power_supply/wireless/current_max" mine is now set at 250000, to double check.
Thank you !

I found a solution on reddit !
Going to App > See all apps + show system apps > Search "pixel stand" > clear cache + clear storage
This fixed my issue so I guess it was A13 and not BCL.
Hops it cals help someone.

That's awesome! Thanks for letting us know.
