USB Fast Charge mod - Samsung Galaxy Nexus

Hello I was wondering if there is a mod to have usb fast charge when plugged into the comp. I just came from a Inc and there was a mod flashable through cwm. it was very nice. it charged the phone just as fast as an outlet, if not faster. is there a mod?
thanks

Interesting... I'd be interested in this as well.

+1 this would be great!

Agreed, awesomeness would ensue.

the developer behind it for the htc Inc was chad0989
. he made the incredikernels and the incredicontrol app. tried to use incredicontrol app just for fast charging but didnt work since the kernel doesnt support HAVS or SVS. Im on Francos btw

Imoseyon said once any speed charges were done by taking code out that slows it. Nexus doesn't have it in kernel now according to him so not likely.

Would there be a way to selectively trigger AC mode as opposed to USB mode?

just asked this in the IRC chan and few devs said doing this could mess up your computer system. point of the hack would be to trick the cheap car chargers into giving u the full charge, not the computer.

Not many motherboards have USB ports capable of supplying current in excess of the spec 500mA.
Research modding your (car?) Charger to be detected as AC charger instead of USB.
Sent from my Nexus Prime.

What about a mod that allows the 3 pogo pins to receive more than 500mA(recognized as USB)? That seems ridiculously low and is far more relevant/needed. If you want to charge through the pogo pins you are just SOL.

Moved to General.

I haven't seen a device that can't do 1A over USB in like a decade.
Hell, even non-PCs have no problems with it. I've done it off a Wii before just for fun.
A lot of newer motherboards can even do 2A over USB (to charge iPads). Most ASUS boards in the past 2-3 years have this as an advertised feature (asus ai charger).

Very interested in this actually. Not so much for USB/AC charging on a computer, but for MHL AC charging.
With the current MHL adapters (even when plugged into an AC outlet), the Gnex reports USB charging. To make maters worse, the screen does not shut off on the Gnex. After an hour or two your battery will die. 500ma is just not enough.
The MHL spec says that 500ma is the charging spec. However, I tweeted with Tim Wong:
http://twitter.com/WongTim
He is the president of the MHL association and he said 500MA is the minimum, not the maximum. My quess is that the Gnex won't try to draw more than 500MA since the data pins can't be shorted on the MHL connector.
I think the MHL adapter will provide for more current, just like most laptops and desktops.
With this mod, it would be nice to tell the Gnex to AC charge. Tim suggest that the phone should not draw more than safely required so long as the voltage doesn't drop on the MHL adapter/MHL tv.
I think the Gnex, by design looks for the shorted data pins and doesn't try to push the envelope as far as monitoring the voltage drop on a USB detected power source.

I recall reading about some smoking/dead phones from fast charging mods. Thanks but no thanks.

I came at this problem from a different angle and accidentally found a solution for you. I have an iPad and it wouldnt charge from my PC so did some research and came up with this:
http://event.asus.com/mb/2010/ai_charger/
Its a free driver from asus that increases the max amp on USB bus. Supports most mobos and works awesome on my PC and dell laptop, I can now charge the iPad on there.
It also has the benefit of fast charging of my Nexus. Double win.
EDIT: Ignore the ****ty site design, it looks terrible but does as it says

Just installed and will give it a go. Wish me luck people.
Edit: Didn't work for me. Same charging speed with and without it.

Here is a pm back from chad:
I'll look into it and see if I can come up with something for the gnex also. I do not plan to release a kernel, but possibly I could provide a patch.
Can you get me a kmsg (/proc/kmsg) while you plug your phone into an AC source, and then a USB source?
adb shell "cat /proc/kmsg"
Also a log of the power draw while connected to USB and to AC
Thanks

there is no "right" output
most usb ports will charge up to 500mA
the stock usb wall charger is, i think 750mA, i havent looked at it in awhile since its behind my desk, but i know its not 1A
the oem nexus one wall charger (non usb) will charge up to 1A
I would only recommend a 1A charger because there's no point to use a lower amperage, it just takes that much longer to charge your phone.
Couple of good threads on this topic, both on the vibrant and the i9000 acessories thread. Lots of good info. The deal extreme chargers look promising. Waiting to hear from a person who bought a 2amp charger if the extra 1a is used by the phone especially when using gps.

well, my phone will still charge (slowly) while watching avatar, which i would assume is a pretty high load on the cpu, using the 1amp charger i got from dealextreme.
fwiw, the one i have is a 1A "HTC" wall charger thats square and lights up HTC when charging, it ****s up my screen sensitivity so i wouldnt recommend it, but it was only like four dollars so i'll live with it.

AC charger or car charger?
The charger does not dictate the amount of current given to the phone. The phone will only draw what it wants to. The charger can limit the maximum current but if the phone only asks for 700mA, a 2A charger will only provide the 700mA demanded by the phone.
I don't know what the max current our phones will use but having a larger charger will only help if the phone requests the larger current.

I'm not sure how stressful watching Avatar is from a current draw perspective. The torture test is to turn on 3G, Bluetooth, synch, GPS and run the Navigation app while driving. Some post indicate that only a true 2A charger will be able to do this w/o discharging the battery. 1A ones can only limit the discharge. Cheap ones empty quickly.
Could you check what your charge current file value is for your 1A DE charger? Make sure to use the original Samsung cable and cross check with the original Samsung charger and a USB port.
1) Use an application like ES File Manager or Astro Filemanager
2) /sys/class/power_supply/battery/batt_chg_current

i checked the file when using the HTC cable plugged into my work dell and it said 850-860 after checking a a dozen times
plugged into the wall charger now and its around 700-750
is that supposed to be reporting in mA?

Yes, but I haven't heard that anyone has measured it. The numbers you are getting are consistent with what others have see. 800-900 for USB. The original Samsung 700mA charger is getting 900-1100.
If you have another Android phone try that one as well to see the differences (e.g. G1 ~300-400).

Thanks for the relay, great find! With these newer devices it really makes sense and heck, why to I need seperate power bricks for my USB hub, speakers, and mouse charging base. Getting to a single USB cable would be ideal down the line. I had just ready recently how Apple has adopted the Thunderbolt cable for something similar (though not as powerful watt wise). It's a good trend. I can't wait to get a desk that doesn't have a rats nest zip-tied under it

Its actually about the same if you use one of the following charging/data cables linked below. I have both of them. I use one for my car and one at work. I was actually very impressed by the quality and function of these cables for what I paid. I plug in my tab at work to charge via laptop usb when the battery is below 15% and it charges it to 100% in about 6 hours. If you are looking for an extra cable, I highly recommend the first one.

With everything going greener I'd expect all but some high end systems have plenty to spare from the 300-500 watt PS. Heck, smart PS with the right USB implementations could allow charging with the PC off for these gadgets and even cutting the power to charge off when it senses the devices are charged. It's all spes and who follows them though. Pretty cool even if it works for just a few features.

I doubt you would be able to use this in Laptops. My laptops power supply is 90W, they would have to double the size of the power brick and that would be annoying. But, for desktops, this could be nice with like a 600W PSU.

[Q] Galaxy nexus MHL/HDMI

Hello guys,
Lately I have been using the MHL/HDMI cable for gaming on my Galaxy nexus to play Modern combat 3. Since i'v tethered my dual shock controller through bluetooth, Wifi is on for online playing, and the screen is on while playing, always run out of juice!! Even though my phone is plugged to the charger.
so i have been wondering if any of you guys could help me put my screen off while plugged into MHL/HDMI. Or help me under volt. thank you
Are you sure your using the correct charger?
Try a 10watt USB iPad charger.
am using the apple 10W USB Power adapter. input: 100-240v ~0.45A.... 50-60Hz Output: 5.1V 2.1A
the white block one
I think the nexus is limited to 1A. Not sure if the limit is changed when using mhl. Also, heat is a factor. It might be possible to get longer play times if you have air flow all around your nexus to keep it cooler. Meaning elevate it without a cover on. And maybe a fan blowing on it.

Q. 4
Pogo pin charging seems like our only hope.
Came here to ask the same question as no matter what adapter I used it showed charging USB which for gaming isn't enough by a long shot. Good to know i'm not the only one.
Is there a way to get the kernel to ignore the type of connection and draw as much power as is possible? Similar to how many of the tablet kernels were modded to allow charging over USB and not just the adapter that was packaged with the device.

Has anyone tried a charge only cable? These are the cables which have a short across the data pins. I know it's a long shot since the AC charger should cross the same data pair.
I hope there is some XDA magic that can be applied to draw more current. I have a feeling it will require a hardware tweak of the MHL adapter and driver level hacking of the silicon image chip.
I have tried a few different AC adapters including the blackberry, HTC, and a random LG charger and they all showed as charging as USB and not AC. I would imagine it is in all MHL adapters and/or the phone.

[APP][ROOT][KT] Fast Charge Toggle widget

I love @ktoonsez kernel I also LOVE his fast charging option. Was using schools computer to charge and was charging at 900 mA love it.
Got tired of going through the app to toggle this. So i made a widget that can be placed on the home screen or the lock screen. Im sorry, the image is hideous. xD wasnt too sure of what to use as an image so bear with me xD
Just install the APK then either on your home screen or your lock screen add a widget and select Fast Charge Toggle. Done. Will prolly work on other kernels with fast charging option but only tested on @ktoonsez kernel
From almost totally dead, it takes me about two hours for a full charge with normal charging.
I've never bothered with tweaking charging settings. How much faster would fast charging accomplish the same thing?
Like the idea, but what does fast charging do ultimately to you're overall battery life and health long-term?

It has no side effect on the battery. The stock charger has I think like 2a charging power, most computers have only 500mA. Fast charging simply tricks the kernel into thinking it's plugged into a wall outlet and charges at the full power available. The only side affect is that it could ruin the USB port. However after two years of using it I have never seen any issues myself nor have I read any.

According to what I personally saw in the source code and what @ktoonsez said, the fast charging gets ignored when it's an ac charger. Just going off of source code and what the code actually does. Might just be a placebo effect on your end all in all tho fast charging sure is the best thing since sliced bread xD

I have a car charger that has a spare USB plug on it. If I use the actual car charger it charges as normal, but when I plug in the white USB cord that came with the phone into the same car charger it definitely charges almost twice as fast. Living proof. I was on a road trip using GPS and LTE while streaming music. While on the car charger it would almost not charge at all, just supplement enough to not drop in percentage. Then, when I switch to the other USB it charges up no problem.. Really works.

First off, Thank you for making this and sharing it to the community. I have been looking for something just like this. Comes in very handy.
I don't know if you update this anymore, but I was wondering if you could make a choice for different icons for the widget. If not, no big deal, the icon is just a little too cartoon-y for me.

I just googled "maximum usb milliamp output from a standard computer usb port" and to my
surprise I must have found at least 25 links which I read that deals with this subject.
And all of them specifically point out that a normal laptop or desktop computer's usb port puts
out a maximum of 500 milliamps unless someone has some special usb pci/pcie card installed
inside their home computers, I never seen any that do but it is possible that such a card exists.
So this mod would really not do anything at all, it would not charge faster and it could not hurt
the usb ports of any computer since it cannot change the max. milliamp output of the usb port.
Now if we had some kind of special program which we install in our computers to allow the usb
ports to put out 2amps (2000 milliamps) then it would charge just as fast as our wall AC chargers do.
But modifying anything inside our phones cannot change the fact that it's the computer and it's usb
ports which determines what the maximum amount of milliamps that it can output.
Look at it this way, if you have a 5 gallon gas can you cannot pour 10 gallons of gasoline out of it.

The maker of this (ktoonsez) stated this in his thread. However, a lot of computers (newer ones) do have higher power outputs to power things like external hard drives, cooling fans... etc. For instance, mine, when paired with the fast charging mod, outputs 700ma but without, stays at 500ma. So while you are correct, there are a lot of computers (especially newer) that do have huger output ratings. This is clearly seen when my external hard drive won't work on my grandfather's dinosaur computer (even his new printer has issues). But plugged into my laptop, it's has no problem.
Also, I believe USB 3.0 has a 1amp output.

You know what, you are just about right, I just did some more googling and found
that the usb 3.0 ports on newer computers do have a greater output than 500milliamps.
They have a maximum of 900milliamps, still no where near the 2000milliamp which
the home charger puts out, but it's close to double of the standard usb 2.0 ports.
I read that many newer computers including mine has a dedicated 3.0 port which stays awake
even if we turn the computer off & it continues charging whatever is plugged into the 3.0 port.
So 900milliamps is a lot better than 500milliamps when comparing usb 2.0 to 3.0 however
current is current, the phone itself cannot distinguish between a 500milliamp or 900milliamp
charging rate, if it gets 900ma it will charge a lot faster than if it only gets 500 milliamps.
All cell phones have a safety feature built into their circuitry which prevents us from charging
the phone at a higher rate than what Samsung specifies by plugging it into a charger which puts
out more than 2amps, if the phone did not have that circuitry it would dramatically shorten the life
of the battery.
That's why Samsung ships 2amp home chargers with their phones and not a 2.5 or a 3amp one.
If this mod which is being discussed here defeats the safety feature in the phone's circuitry which
prevents it from being charged too fast then I would highly advise against installing or using it.
The only time a higher rated battery charger should be used is if we have an extended battery
which was rated at let's say 4200milliamps in which case a 3-4 amp charger would be best.

You know what, you are just about right, I just did some more googling and found
that the usb 3.0 ports on newer computers do have a greater output than 500milliamps.
They have a maximum of 900milliamps, still no where near the 2000milliamp which

It doesn't defeat the security of built in kernel protection. Androids own API has a way to detect if the plug is wall charger or USB. The mod simply tells android OS that the USB charger is an AC charger and to not limit charging to USB levels. That's why USB doesn't work when the mod is enabled. It's no way harmful to the device. Been using it since I've gotten my phone and even back on my s3.

I love @ktoonsez kernel I also LOVE his fast charging option. Was using schools computer to charge and was charging at 900 mA love it.
Got tired of going through the app to toggle this. So i made a widget that can be placed on the home screen or the lock screen. Im sorry, the image is hideous. xD wasnt too sure of what to use as an image so bear with me xD
Just install the APK then either on your home screen or your lock screen add a widget and select Fast Charge Toggle. Done. Will prolly work on other kernels with fast charging option but only tested on @ktoonsez kernel

You're right!! The widget is the ugliest thing I've ever seen but it works perfect! Thank you much!!

Okay, see what you mean.
Did you know that there are 3 or 4 free apps at the playstore which display the amount of mA
the phone is being charged with at any given time, it also displays the maximum mA that the
charger or usb port can charge. Here are a couple links in case you or anyone is interested:

Charging The 10.1

I lost the original charger to my 10.1 2014 Edition and I've had problems ever since. Earlier this week I thought I would order a Limefuel 24W 4.8A dual port rapid charger. I thought to myself: Hey I can untick Power saving and have all my needed apps running. Even using a root mod to run 4 way multitasking. Yet it's still sucking up more juice than the charger is spitting out. Am I doing something wrong or did I get a faulty unit from China? This was NEVER a problem when using the Damn Samsung charger along with the foreign adapter dongle it shipped with. I thought getting one so powerful would charge it even faster.
Maybe I should just ship it back and get an official unit from Samsung? Although I don't see how getting less energy will make the tablet charge any better

4.8 amp should do the trick. Could be a fake unit. Is it heavy? 4.8 amp is pretty much, so it should be as big as a lap top charger.
But remember , a cheap usb cable may also be the problem. Try a short one of good quality.
Edit.Just tried a 1.2 amp Nexus 5 charger on my P605. Charging good on full brightness.
Thanks

The charging circuitry and s/w on the device determine charging speed. Do a search. Someone posted the different charging amperages using the stock charge and Apple and HTC chargers and USB cables. The device detected the latter and charged at about half of the former.

Yes thats obvious and i doesnt even need to " do a search ".
The problem was it wouldnt charge at all.
Thanks

Does the p600 also not charge correctly with a non samsung charger? I remember my p1000 requiring an adapter that had a resistor between two connections to charge correctly at a laptop or different charger.
