[Possible mod] Pixel 3 Fast Wireless Charge - Google Pixel 3 ROMs, Kernels, Recoveries, & Other

Pixel 3 enables fast (>5W) wireless charging only on Google certified chargers, and there are only a few of them.
On most QI-compatible chargers it will pull out max ~750mA charging current by default (checked by Ampere / 3C Toolbox and simialr apps)
However, there is an interesting control file in /sys/class/power_supply/wireless, voltage_max.
It has default value of 5000000 (5V), and you can write values of up to 9000000 into it (9V), which surprisingly is accepted and leads to more charging current.
However, this should be done while wirelessly charging (as file does not accept writes otherwise).
Code:
echo 9000000 > /sys/class/power_supply/wireless/voltage_max
# Now, check what we've got
grep . /sys/class/power_supply/wireless/voltage_*
voltage_max:9000000
voltage_now:8568000 # Means it has been raised by device
After such write, charging current can be as high as 1290mA (compared to 700-750mA stock).
This change reverts after the end of charging session, however.
Question to kernel devs around here - can this be made permanent in some of custom kernels, or have a SysFS switch like "USB3 fast charge"?
The issue is to find where the default value is stored and alter it there.
EDIT Currently this can be made permanent by means of Magisk module "Advanced Charging Control" (https://forum.xda-developers.com/apps/magisk/module-magic-charging-switch-cs-v2017-9-t3668427),
by adding the following to config:
Code:
onPlugged=./wireless/voltage_max:9000000

Nice find. Given how many folks are ending up with useless Pixel 3 and 3XL devices after using off-brand wireless chargers I am hesitant to use one even with the Google empowered limiters.

Have you verified that the charging speed actually increases?

Yes, battery charging current reported by Ampere app is higher. And the battery charges faster (in % per minute)

Can anyone else verify?

Confirmed it does indeed charger faster using a Samsung wireless fast charger and a cheap $6 ebay chinese wireless charger. Enabling 9V DOES cause some slightly audible "ticking" noises every second when playing ear next to charger. Normally its completely silent.

I've added this to Proton Kernel as part of the standard "USB fast charge" option that EXKM, Kernel Adiutor, and FKM can tune. It's disabled by default, but please read the following disclaimer thorougly before enabling it:
Think twice before enabling fast wireless charging because cheap chargers can cause your phone to heat up significantly, harming the battery permanently. They may also cause temporary issues with your phone (such as ticking sounds) or permanent damage to internal circuits. However, if used properly with a high-quality charger, there should not be any issues. Enable at your own risk. I am not responsible for any damage to you or your phone caused by this feature.

That being said, several users have gotten good results after enabling it. It's ultimately a question of how cheap your charger is.

I am not sure how true is this, my Pixel 3 charges at 1850mA by default without any modification thru wireless charger and 2900 mA with a wired charger. I am using Pixel stand and Pixel 3 charger.

This is for non Pixel Stand owners to get closer to the speed of a Pixel Stand.

If possible for fast charge now, can someone locate the trigger for the special pixel stand charging dock screen?

That needs someone with the Pixel Stand (e.g. not me) to investigate.
Or, at least do the following while the phone is on the stand, in the terminal:
Code:

grep . *
and post the output here.

Does anyone know the safe/recommended wireless charging temperature range? I want to do some comparisons of different wireless chargers I own and see if they're within tolerance. Thanks!
EDIT: Actually, if anyone can tell me what the Google Pixel stand normally gets the temperature up to, then I'll have a benchmark for comparison. Thanks!

Trying to prepare for this test. I only know of one app that can chart temperature over time but it only allows 200 data points so I'll have to set the refresh rate at 30s which will allow 1.6hrs of recording. I'll have to test from 50% to full and hopefully that'll give enough data. I wanted to test from 1% to full charge but that would mean I have to set the refresh interval to close to 2min, which would wash out temperature fluctuations during those two minutes. Do you know of any app that can chart temperature over time with more than 200 data points?

I do not, but I think that should be sufficient. Maybe a second test from 0 to 50% some other time would be useful as well.

Yeah I can try that too. But I wanted to see how it behaves over the whole range. It's possible if going from 1 to full might give higher temperatures since the cells will be heated for longer. I guess I'll test 1-50 then 50-100 at 30s then another test 1-100 at two min intervals.
Edit: Miscalculated, 60s from 1-100 should be enough. That's more than 3 hrs. I doubt it'll take that long to fully charge

Started the first test. Going from 50-100 with case off and pixel stand app cycling through photos. Next I'll go with the same but turn off photos and leave just the clock in ambient mode. I'll then test the same as the first two with case on. So far it's charging at 1%/min so I set the refresh interval to 15sec. That'll give 50min of data, just enough for the full charge from 50%

[KERNEL PATCH] Force AC (fast) Charging - patch complete

This is for kernel devs only. The patch itself is useless to those who do not/can not compile their own kernel.
This was a pretty big hit on some other devices so I figured I'd give it a shot for you gys. This allows one to force AC charging for any charger that is detected as USB (e.g. many car chargers) and pull the full current the charger can support. It also provides additional security when connecting to public charging stations because by forcing AC charging, USB/adb data transfers are disabled, protecting your data.
It is essentially a software version of the modified charge only usb cables.
Fast charge can be toggled by issuing:
echo 1 > /sys/kernel/fast_charge/force_fast_charge
and off:
echo 0 > /sys/kernel/fast_charge/force_fast_charge
In addition I have created a toggle fast charge widget that may be used to toggle fast charge on and off right from your home screen:
https://play.google.com/store/apps/details?id=com.incredicontrol.fastchargewidget
I have also implemented a toggle in IncrediControl (free) that will allow you to turn it on and off.
https://play.google.com/store/apps/details?id=com.incredicontrol
For the widget (or any fast charge toggle) to work, you MUST be running a kernel that has this patch implemented.
As a good gesture to support a fellow dev, I ask that if you implement the patch into your kernel, please link to my widget as one means to toggle it. You are of course free to provide other ways to toggle it as well if you so desire.
Kernel devs, if you would like to test the widget yourself to confirm its working, and for convenience of testing, please contact me and I will provide you with a copy. You must show that you are a kernel dev though (i.e. link me to your kernel post so I can match your username).
Good luck have fun!

Thank you to those who tested for me.

When on, it will be detected as AC for any source normally detected as USB. This includes your computer. Not every computer can put out enough amperage to significantly increase charge speed though. So it depends on your charging source. Even if your charging source can't put out more than 500mA (what USB charging is limited to), since the phone is in AC mode, it will be able to sleep while connected to the USB source so you will see some small gain because of less power usage from the phone.

When you have the feature toggled on, the phone is in AC mode and all USB transfers are disabled. Turning it on and off is as simple as tapping the widget or opening an app and unchecking a box though.
Tap the widget on (or other means of toggling) - AC mode
Tap the widget off - Auto (detects based on charging source like stock)

Fast charge? I remember having that on the DHD, Lord Clockan's work. It was great having that extra overcharge + fast charge...
I'm no dev, but having this feature on future ROMs would be very nice.
-----
Any chance you can max the current input? I mean... it begins at >+900mA when the battery is very low, and the current slows down as the battery charges.
Also, when playing a game that, say, consumes about -400mA and the current input is +800mA, the current will slow down to +400mA only (since another 400mA are being consumed by the phone). You can immagine what happens when the battery is almost full and you're playing a game...
I am guessing that having the current input always maxxed out would charge the battery (a lot) faster. Would that damage it, too? If not, could it be implemented?
in experience, below 80% the numbers are as per below
900+ ma WALL PLUG
400+ ma USB
600+ ma CAR CHARGER
these are rough numbers, not accurate
after 80%, they tend to be slower

I can't press "Install" while Filter Screen / Screen Adjuster is running / turned on. That's the only thing that prevented me from installing apps until now... If you have that installed, I suggest you turn it off for the time you're installing apps.
Otherwise... I don't know... Wipe cache, dalvik, fix permissions, zipalign apks...
Id love to see this implemented.. im running the standard LeeDroId kernel.. id happily flash it over the top if that would be of any help. I do 80% of my phone charging via USB.

I would be concerned with heat buildup and possible damage by pushing that much additional current. Not to say its not possible, but I would be leery of implementing it.

As I thought. Not going to make a fuss about it, it was just an idea; I knew it could be dangerous
I bought a pack that had a car charger and a wall charger (both of supposedly 1A output) - lighter than the battery cap of the EVO 3D, rofl. The car charger worked perfectly (the power output was meeting the expectances). The wall charger barely sends 30mA (ROFL). In the pack, I also got some sort of expandable Apple cable. The entire "pack" was cheap Chinese crap, I paid ~$3 on it.
I still have the oh-so-good wall charger. It didn't push much current to the Desire HD even with the fast charging kernel...
Guess in cases like that, there's nothing any kernel patch would be able to solve, eh?

I just installed that newer version of BMW. Selected HTC Evo (test) as mA retrieval method. Battery is at 90% and the input current is +305mA. Also, I disagree that the phone takes +900mA from the wall charger when the battery is under 80%. Input over 900 is only when the battery is like under 10%... At 50%, for example, it isn't +900...
ive got 3 wall chargers, and all of them are original from the phones I bought respectively, HD2 HD2 and EVO3D
they report about 900 below a certain %, and it could be 40% , 50%, 80%, etc
i guess you get the drift
anyways, you are supposed to select Automatic to get proper drain readings
forgot 2 mention that
Still need a tester to PM me. Have a test kernel ready to go, just need confirmation so I can post the patch.

[Q] Is there an app which can show charging current ?

I’m wondering if there is an app that can show the charging current in mA ? I have come across few apps (i.e: Battery Monitor Widget) which I believe show the power drain, but not the input current while charging. Also the current reading of the Battery Monitor is inconsistent and fluctuates a lot (which I believe is due to the CPU stepping between different frequencies due to various background apps??). Is there a better (more reliable) app that can monitor the actual input instead ?
I have 2 car chargers : An old Samsung CAD300 (rated at 5v/700mA) and a new Belkin charger (rated at 5v/1A). but neither of them can provide enough power to charge my HTC One X while using Google Navigation and streaming audio over BT. Belkin is better at minimizing the drain, but still battery level drops gradually. I modded the Belkin charger by shorting D+ and D-, now it performs much better (earlier the drop was far worse than even the Samsung charger). but want to see the actual output, and hopefully try to find a better charger that can provide enough juice to charge the phone while navigating. I borrowed few chargers from some of my friends to test, but Battery Monitor Widget's reading was too unreliable to accurately test the performance.
EDIT: I do have a multimeter, I guess I could also use that along with a 5ohm resistor (in series) and measure the current to see if the charger is capable of outputting 1A, right ?

Thanks for the suggestion, but I cant find the value of charging current anywhere in Elixir 2 (at least in the free version). Under Information > Battery > More information, it only gives one current value titled "Current" but that shows 2300mA right now when plugged in to my computer over USB. Which is obviously wrong, no idea what that value is though..
Seems to me like all these apps are displaying random numbers for the current value, or these apps can’t read it property on the One X

safe to charge constantly at 33 wat?

Hello guys,
So the other day I was messing with thermals and I flashed a thermal that basically removes entire thermal throttling. Because of that, I was able to charge my phone at 33wat constantly for about 20 mins. The charging speed was super awesome, but I'm wondering is it safe to do so constantly? When I was back on stock settings, the charge speed would randomly fluctuate b/w 10-18 watt but with no throttling it just constantly remains on 33watt.
So again is it safe to keep charging my phone on these higher voltages constantly?

Not knowing enough about this, I'd assume it's not safe and that heating of the battery would be the issue and would lead to your battery being cooked over a series of charging cycles, but I see your point temperature was not excessive (34°) - I'd advise using an app to record moment by moment charging temperature
Assuming you didn't have your phone in a pool of cooled mineral oil during charging I'd assume that you've just become a test pilot. Let us know what happens... [consider also the possibility that your house might burn down]

OK thanks for your insights. Yes I did some research on my own. Particularly from battery university (yes that's a thing, a whole website..) and I learned that as long as your battery temp doesn't hit 50c you can do whatever you want because in the end your phone only ever draws enough power that its circuitry was designed for. So that information was enough for me to continue my journey into hotter waters.
So far, during charging from 49% to 80% my poco only took about 17 mins to reach there and right when it reached 80c that I saw it start to throttle a bit so by the time it was 82, the watts came down to 25-28 range. So I guess that's hardware throttling in effect since I have already got the software ones removed? And anyway during these 17 mins, while the ambient temp at my place was 32c, the battery temp soared as far as 43c. I believe I would frequently hit the same temp even when I had all thermal enabled running on stock setup. So we can safely rule out that it didn't happen because of not having thermals but just because the ambaint + charging had their own way.
Lastly, I would continue doing this for few more days checking under air-conditioned room next and see how it goes. For now I'm sticking with 20-80 battery rule because that's supposed to be the safest thing in the world of li-on batteries.
Normally quickcharge will keep stuff safe so it will adjust accordingly.
If temps would get over 40-45 deg. c. over a long time it would take a hit on the 'life' of the cell.
Charging slow and between a range of 10 and 90% will help cell life for sure.

It's a file system for android, and yes it does make quite a decent (not like huge) difference when you load up apps (f2fs is usually used in the /data partition) basically apps open faster and it makes the phone feels snappier.

Lastly, I would continue doing this for few more days checking under air-conditioned room next and see how it goes. For now I'm sticking with 20-80 battery rule because that's supposed to be the safest thing in the world of li-on batteries.

But, how long does it take to reach 49% from 0% or from 20% as you say you follow the 20-80 rule?
Removing thermals is not a good idea, I'm not an expert but I get more fluid experience playing CODM , capping the max speed of all proccesors to 1.7ghz , and keep the phone charging at low voltage. I can play for hours at 60fps and the battery never hits 44c. Removing thermals and processor's cap, I would have a great 15 minutes of game and then it would be very hot and hardware throttle, to the extreme of even get only 20 frames /sec or even less.
All that heat is bad for battery and the components. The battery will go bad faster, inflating in worst cases, and the IPS panel can get permanent ghosting. I know this from previous devices poco included. I do gaming for hours. Removing thermals + gaming at high brightness is bad.

Um, you don't just remove thermal limitations and charge like yesterday.
That is useless and in some cases counter-intuitive.
You highly decrease the temperature to 14 degree Celsius to 26/28 Degree Celsius and charge in that.
However as you say, if you're doing high intense activities that use a lot of hardware, which generally heats the phone, then having a heated phone for extended periods of time *might* be bad for the battery, well having any electronic device heated is bad for the internal circuitry. I have a personal experience with this.
That said, as long as you're using your phone for mild to medium intensity activities like watching multi-media applications and surfing, calling, etc removing thermals will have no significant issues and not reduce the battery life because your phone is mostly never going above 35/36 degree Celsius.
Or if you can, remove thermals whenever you're charging and put them back on whenever you're not.

Hello guys,
So the other day I was messing with thermals and I flashed a thermal that basically removes entire thermal throttling. Because of that, I was able to charge my phone at 33wat constantly for about 20 mins. The charging speed was super awesome, but I'm wondering is it safe to do so constantly? When I was back on stock settings, the charge speed would randomly fluctuate b/w 10-18 watt but with no throttling it just constantly remains on 33watt.
So again is it safe to keep charging my phone on these higher voltages constantly?

How To Guide How to limit charging on Pixel 6

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.
/sys/devices/platform/google,charger/charge_start_level:75
/sys/devices/platform/google,charger/charge_stop_level:80
EDIT: You need to be rooted to do this, and you need to reapply the settings after reboot.
I have a Tasker action that does this automatically 5 minutes after rebooting.
If only there was a way to use that without root :-S
What would be the purpose for this.
I always charged to a 100% and never had issues on my devices.
I use the adaptive charging overnight and think that will help with battery life.

If you do some reading you will see that charging over 80% and draining under 20% will significantly shorten the lifespan of your battery. This is important for those of us that have devices not sold in our country so getting replacement batteries would be very difficult and expensive. I have phones that are more than 9 years old and still going fine if charged like this.

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.

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

On the contrary. The most recent phones attempt to limit the time that they spend at 100% exactly because it's so bad for battery longevity. Having options like the OP's approach just gives users more flexibility, should they want more control than, in this case, Google's adaptive/AI approach.
And it's not 'wasting' 40% of the battery. Keeping between 80% and 20% just optimizes battery service life during those days you only actually only need 60% of it's possible capacity. When working from home that's often the case for me. I actually tend to use ~30% of the battery in a day. Better to charge it up daily to about 70% than all the way to 100% and let it go down to 10% over 3 days. If it's easy to do, why not?
Not quite the same, but EV design also has their batteries normally operating in the middle range so as not to compromise their service life...
Definitely not myth. The only myth is that lithium cells exhibit a memory effect and need to be deep discharged and fully recharged periodically to maintain their capacity. It's actually bad for them to do this! The only reason to do this would be in an attempt to recalibrate the software for the battery level gauge (at the cost of a little damage to the battery each time you do that).

Most folk don't notice reduction in battery capacity until it becomes severe. For example, a friend claimed it wasn't a problem charging his iPhone to 100% ritually. When he checked the OS, it said his battery capacity was 80% of what it was when new. He said he hadn't noticed it affect how long the phone lasted.
If your usage is such that you can predict how much capacity you need, you can choose to charge to 100% only those times you will actually need that capacity. Other times you can look after the battery so it's able to actually give near on 100% for longer, those times it's important to you.
Others who keep their phones a short time or are comfortable with the cost & inconvenience of a battery replacement, or simply don't care, don't have to worry....

This all maybe good if you are planning on keeping your device for a few years.
Most people buy a new device every other year. If not once a year.
... and if you really want to knacker the battery, heat it up too!
Worst case scenario - using a sat nav app on your phone in the car on a hot day with the phone plugged into a car adaptor. It's going to be sitting there at elevated temperatures, possibly with the sun shining on it, whilst being kept at 100% battery....
I'm only a customer (and have no other affiliation) and like to tinker, so I got one of these for use in the car to limit temperature when charging and limit max charge. Not cheap, but ok compared with the cost of the phone https://chargie.org/
I'm sorry, but at the snails pace this phone charges I'd be very surprised if charging it to 100% every night will make any noticeable difference in the long run. I had a Xiaomi Mi10 Ultra with 120W fast charger. That phone used to charge from 0% to full in like 20 minutes. Now that's one way to quickly kill your battery.
The Pixel uses your alarm to adaptively charge the battery so it should never overcharge it anyway. I'd much rather us all of my battery than use it only between 20 and 80% just for it to last a little longer.
The files are overwritten on reboot so I created a Tasker task to write the values on reboot each time.

On what basis? All the research and tests are based on charge level not charge rate. Fast charging potentially just makes it worse...
But at the end of the day it's your phone. You'll charge it in whatever way works for you.
I feel like this post sort of misses the point. It clearly is aimed at those intending to keep their phones >1yr, it is stated explicitly.
I'm not rooted right now, so I've been using the AccuBattery app. One of the things it does it gives a notification every few minutes when the battery is at 80% or above so that you can physically unplug the phone from the charger. Obviously having this done automatically would be better, but I've been surprised at how well the notifications have worked in my case. Plus, I can always leave the phone plugged in if I know I need a full battery for some reason (ie a long day away from any charging source).

Dumb question but what did you use to write values into those files? Did you use a text editor (with root access) or just termux or something? I tried with the built in MiX text editor but it seems to choke once I open up the file.

I used FX File Explorer (root option). Look for the #. SYSTEM (Root).
I was wondering if changing the file permissions after writing to them to read-only would make the changes stick, but I am sure the OS could still overwrite them...??
I wonder if there's a similar variable to tweak at what temperature the phone considers the battery is too hot and stops charging?

Did a bit of testing and it works fine. A few things I noticed:
1. Doesn't survive reboot. Now that I've set up MiX with pinned folders, I can make the change in seconds. Need to sit down and read through the acc documentation because AccA doesn't work. Would love to have an automatic solution. Miss my old Battery Charge Limit.
2. charge_start doesn't seem to matter. After all, if charge_start is set to 75 and the phone is at 70%, it shouldn't charge. But it does. I've kept mine at 0.
3. Point #2 is kinda beside the point, though, because charge_stop will stop at the set value and stay there. No noticeable increase in temperature from what I can see. Definitely less than when charging.
4. Still shows as charging rapidly when it hits the level. Is it rapidly cycling charging on and off? Or in a kind of micro-current state? Or this may be a true battery idle situation where all power is drawn from the adapter. Ampere and AccA just show "not charging".
Edit: With a bit of use today, it does seem to act like a normal min/max charge deal, so I set it at 75 start/76 stop. Not sure what was happening at first...maybe something to do with the adaptive charging since I still have that on. Either, way, no complaints. With my use case working from home, I have it plugged in most of the day and it'll only take me about a minute to change charge_stop to 100 when I'm planning to go out all day somewhere away from chargers. Not ideal, but still a big improvement. Changes my rating of the thing from maybe 3.5 stars to 4.5.

Question Anyone else using AccuBattery app on pixel 6?

Greetings, I'm having issues with the pro version of AccuBattery not keeping history sessions beyond a days worth. Sometimes nothing is logged at all. I've been in touch with the developers, and they are looking into it. Just curious if others are experiencing anomalous behavior for this app?
I'm using Accubattery pro, and it works normally for me. Currently history sessions go back 12 days for me, typically 2 entries per day.
Two weeks for me too.
Mine goes back to the 17th I use a chargie to limit.my.charging to 80 so there are lots of entries because it shuts off at 80 drops to 76 then back to 80 and accubattery records all that

Hi, thanks for responding, can I ask what range you typically are charging from / to? Apparently, from the developers, it don't record cycles less than 20%, however, they indicated they will remove the limit of 150-200 sessions in a future update. My average range is from around 70% to 100% and I almost dayly just use the phone while plugged into it's charger. Also, curious what adaptive settings you have enabled? Thanks.
Curiosity, what if any adaptive settings you have enabled, and typical charging session range from/to. Thanks

I usually charge the phone overnight, typically it's down to about 40% or 50% when I plug it in. Because I charge overnight I use adaptive charging. I also have adaptive battery turned on, but I don't think it usually kicks in.
Thanks for responding, what, if any adaptive settings do you have enabled. And is "chargie" the name of the charger unit you use? And where did you purchase it from?

The Chargie is on chargie.org. I bought one but didn't like it so I gave it to my wife who charges all day and now limited to 80%. I don't use any adaptive settings and my charging ranges up to 90% and then I unplug. I never charged my P5 during the day but the P6 I have to charge multiple times. So I really don't pay much attention any longer. It drops to 50 or 60% I throw it on the charger for a bit and then do it again and again. The battery sucks but I like the phone so I live with it. I'll def trade it in for the P7 hoping they iron out some bugs.

I Have adaptive charging off I think ill check later my phones in the other room. But chargie is a device that goes between the any charging brick and the phone.I t connects via BLE (Bluetooth low energy) and is controlled by an app from the playstore.
https://chargie.org/product/chargie-c-basic/ That is the link for the usb type c model. I have had all three of the generations of this thing. Been using it since my og pixel. I actually have my wife's old pixel 3 that she used for 2.5 years and now has the 5a but the 3a is used as a security cam now and that phone has always had a chargie and the battery is reading 101% Thats pretty amazing for a phone that old especially since nit has spent the last 6 months or so continuously plugged in because its a camera now.
