This is for kernel devs only. The patch itself is useless to those who do not/can not compile their own kernel.
This patch allows one to force AC or USB charging for any charger. It also provides additional security when connecting to public charging stations because with either force AC or force USB mode on, USB transfers are disabled, protecting your data.
Fast charge can be toggled by issuing:
echo 1 > /sys/kernel/fast_charge/force_charge_mode
Slow charge:
echo 2 > /sys/kernel/fast_charge/force_charge_mode
and off:
echo 0 > /sys/kernel/fast_charge/force_charge_mode
Plug your phone into the charger AFTER toggling the desired mode.
In addition I have created a toggle fast charge widget that may be used to toggle fast/slow charge on and off right from your home screen:
https://play.google.com/store/apps/details?id=com.incredicontrol.fastchargewidget
I have not yet implemented the three way toggle into incredicontrol (free), but I will be. I have to change it to support slow charge also and haven't yet gotten the chance to. I will be implementing it when I get the chance though so you guys have a convenient free way to toggle also.
For the widget (or any fast/slow 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!

Its not necessarily just for car chargers, that's just the easiest example. It can be used with any charger that is detected as USB. Some powered hubs for example can easily put out 1A but would still be limited to 500mA by the phone. The patch will allow you to toggle force AC mode on/off via an app or widget.
Ya i got that but the only usb-charger besides the outlet that i use is my laptop, and i use it only for transferring files. still a great idea!
In other words. If you will be using USB port and cable as current source, The specification asks for Data + and - to be shortcut. And normally phone detects it and also the fifth sense pin and then high current charging must kick in. (although our LG phone uses also it to enter download mode)
If you use the widget and enable high current charging, you'll fry out your motherboards USB port probably...
Another warning. If someone has read about Lithium Cell charging methods AVR based documentation for example. Such high current charging decreases your battery cycle life. So consider those facts first of all!
And those with car chargers... especially cheap ones... in most of these devices are SMD LM317 or LM7805 etc family inside... it will dissipate [email protected]=7W so these sticks will fry out and also blow up despite it can deliver 1.5A - the catch is with proper heat sink.
So So So... dear coders... consult your hardware guys before acting for the good deeds... the cons are more than the gain.

Absolutely not. It would have no negative effects on your battery at all as the current isn't increased beyond what it is for AC charging.
Also you notice nowhere that my recommendations were for using it to charge from a motherboard. Despite that, the current pulled from the board is ultimately limited to the fuse at the port. Even if a device successfully tries to pull more than the board can provide (which the board won't put out anyway), the PPTC will cut off power to the device.
So So dear hardware guys, please read before jumping all over someone.

Then please why I have to repair broken motherboards that Ipad2 have fried a lot? Why? Because they are cheap mate, and fuse is the last resort. And No current limitations aren't implemented there...
I said once again. This 0.5A setting is the most green one, as many manufacturer use as a law!
The fact that some make a PR and tell our device charges faster doesn't overthrow simple chemistry and physics. Ok it will work. Charging the cell with higher current, raises temps and other chemical emissions and it deteriorates faster! So the philosophy is simple for them, the user will kill its battery faster in order to buy a new phone eh? Nice!

I agree with you that it shouldn't be used to charge from a motherboard, although many have taken the risk without issues.
Essentially it is a software version of the charging cables with bridged data lines ("charge only") that many buy and have no issues with. I'm just bridging the data lines in software so to speak. The current draw is never increased beyond the phone's spec. The most important thing is that the end user knows the source they are drawing from is capable of providing the current.
I do appreciate your concern for the community and desire to educate everyone. We need more people like you around.
So with that, each individual can make an informed decision on their own. If anyone is still interested in the mod, shoot me a PM if you want to test.
Yup, there isn't much math to be done here.
Higher current means higher temps, and O2X already has trouble with temps as it is.
However, to each his own, and as long as people are aware of what they're doing there is no such thing as too many options... although me personally I would stay away from this one.
EDIT: Wait... so you're saying that O2X charges at 1A when connected to a wall charger and at 0.5A when connected with USB? I get the point now. So you only risk damaging the motherboard, and not the phone.
I'm guessing it would be more interesting for O2X users to do the opposite! A 'Force USB charging' because from what I see a lot of people get SoD while charging their phones overnight and this might fix it
What do you say Chad? Would you be interested in implementing this feature? I think I would use it!

+1 for force 500mA mode of this would fix the overnight crashing and massive overheat that follows. I don't know if the problem is related to the current level during charging though.

For so many years of using rechargeable batteries, I haven't been a fan of post-purchase "fast charging". But then again, I live in a tropical countries so non-air-conditioned room temperatures come quite warm (especially since we're entering summer now).
I must say that I love the "force USB charging" idea though. I rarely get those, but, it's another troubleshooting possibility for the many users encountering charging/overheating BSODs.

also if you charge the battery faster the battery life will be worse then if you charge it slow
so fast and a bit worse battery life
or fast it slow and a bit better life
you can really feel those difference if you live in a country where it is quite hot
you can try it yourself
charge one day using wall charger and charge next day using computer usb you will feel the difference

Jep Owain is right... I remember old times at my work 6 years ago Nokia 8800 (RM-13), it had a tiny battery and it was the time when chargers changed from impulse type from transformer core types... so with the older slow charger the battery held for 15-30% more. (I suppose the battery is hot, and then the voltage is also artificially higher and in reality it isn't charged to its maximum).
But as I said, don't overdose with it especially with car chargers and motherboards. The phone will be fine. Battery should be changed after a year anyway... it costs for me $10 anyway...

Lucky guy. The O2X battery costs roughly US$ 30 here.
So you guys are saying you get an SoD if you charge overnight on AC, but not on USB?
Reading through the battery driver it looks to me that if the battery gets too hot, it swiches to USB charge current, if it continues to be too hot, the charger turns off so I wonder if your issue is somewhere else. Anyone try to record a log (cat /proc/kmsg > /sdcard/kmsg) overnight and see if you get any messages along the lines of:
[OVERHEAT]: Change Charger setting to USB mode
or
[OVERHEAT]: Deactive Charger
It says it's only been tested with CM10, but might also work with other ROMs. I finally got my Y cable, and I can confirm it works. [Using this cable from ebay, $6]
http://mehrvarz.github.com/otg-power-nexus7.html
This means you can plug in your flash drive or hard drive and use it while on AC power!
Update: for 4.2.x check this dedicated thread over on rootzwiki: http://rootzwiki.com/topic/37755-timurs-kernel-robust-usb-host-power-management/
Big thanks to XDA member t1mur and rootzwiki Timur for making the kernel!
This is awesome, just need to find a y-cable to try this out. Just hope its a stable kernel that doesn't cause any issues.
This is a great step in the right direction! Can't wait to see where this goes..

I don't think so for 2 reasons. Usually even powered usb hubs don't give out power through the input port [The source port of the hub]. And even if it did, it would be 500 mAh [the N7 charger is 2000 mAh], which [edit:] isn't enough enough to charge the N7 with the screen on. If the screen is off though, it will slowly charge it.
Also, apparently this is already implemented in Faux's beta kernel, you have to use echo to enable it [it's explained on the thread].
i am getting the 16GB. i am tired of waiting. I have one last question though. Can this in any way cause any type of damage on my device?
It's allow usb and AC charging or only usb ?
Awesome news, even though I just bought a regular OTG cable about a week ago for a $1.50 (still waiting for it to be delivered from China to the USA [NJ]). Since I just got a full-time job I'm going to sell my 8 GB and get one of the 32 GB versions when they become available so I won't have to worry about the extra cable
Can anybody confirm that it effectively works ?
Also, It would be good to to know:
- which Y-USB-OTG cable is used ?
- which power source, i.e. from a PC (500 mA) or a charger (2 A) ?

I am a little confused. The link says...
When a host mode adapter was recognized, charging of USB slave devices will NOT be activated and instead vbus will be raised in order to accept external charge.
If I want to use something that requires external power like a usb thumb drive, and the charging of usb slave devices is not activated; where does the slave device get the power to function? Is that shared off of the Y cable?
I know exactly what your talking about I have one for my old touchpad, ill try it on my nexus 7 see if it works.

Excited!
Can't wait for this! I'll be staying on top of this topic for awhile.
Alright I tried it using stock rooted using motleys kernel and while I could use a powered usb hub with 2 storage devices and a keyboard It wouldn't charge the N7 simultaneously. Although it didn't drain any power from the device either. Now this could be because of what I'm running or even one of the cords since I won't have a chance till the morning to test a couple more scenarios. All in all it definitely should be possible but may require a different kernel/rom etc. Though the OP asked the question regarding doing it w/o cm10 so ill try and stay within those parameters. On the touchpad I used to do it with cm9, as it was necessary especially with that device mostly only working with its 2amp charger. The reason I would only question cords used is I had previous trouble with an older kindle cable and when I tested it on a device I needed 1.5a it was hovering around 1.35a using my multimeter. Which was causing my Touchpad not to charge because it requires alot of power to charge. Ill update you on any progress and see I'f I can find the link foe the Ycable which I got on amazon awhile back.

Yeah. Now I'm toying with the idea of mounting a network share from a NAS-enabled router and put that in that in the car instead...effectively freeing up the USB port for full normal charging. I don't really like this route though because I suspect waiting for the router to boot every time the car is started will slow things down.
Using CM10.1 (06-14 nightly) on my One (International), connected to a Belkin 1A USB car charger with a decent quality USB cable. The phone discharges slowly in general use, and quickly when using GPS. Looking in battery settings it shows "Charging (AC)", which would suggest that it's drawing the full 1A for charging. I didn't notice this problem on stock Sense, although it's been a while since I used that.
Has anybody else seen anything similar on their One? Is there any useful information I could get from a logcat to give to the CM devs?
Thanks in advance,
Jon
OK I checked on stock and it does drain similarly. Should I just get a more powerful charger or could I have a hardware problem? Tried with 2 different 1A car adaptors.
Sent from my One using xda premium
Have you got a clamp meter or know someone who has one? That will tell you how many amps are going into your phone. It does sound like the charger though as your charger at home should be similar voltage/amps to the car charger only the AC charger needs a transformer and rectifier to step down the voltage and change it from AC to DC, car chargers just step down the voltage a little (12v-5v) so require little additional size. Probably easiest to swap out the charger, they're pretty cheap

It's probably not about the Amp rating of the charger. You probably had a cheap charger unit that couldn't deliver the amperage the phone needed either cos it was using cheap parts or something. A proper 1amp charger will still do as well as your new 3.6A charger

Yeah that makes sense. I just thought that if I got a massively over-specced charger then it would at least manage 1A Would have expected the Belkin one to work properly in the first place but never mind.

The fast charge feature I'm discussing is a workaround the Galaxy Nexus had with some kernels that allowed it to pull higher power through things like USB ports on laptops, car chargers, etc. So instead of charging at the slower USB 2.0 rate, it drew power at almost an AC voltage rate.

interesting, sounds like root and perhaps a unlocked BL would be necessary.
This will probably never happen. For starters, there aren't any custom kernels available for the MotoX.
Two, I'm 85% sure that Fast Charge is built into the CPU--at the hardware level. I know the HTC One has it enabled on the stock kernel. I'm certain that the MotoX has is simply because when I put my GNexus on this charger I have with Fast Charge disabled, it would say it was charging via USB; when Fast Charge was enabled, it would say it's charging via AC. When I put my MotoX on the same charger, it says it is charging via AC.
Hope that helped.

The only way to accurately read the input rate into the wireless charger is with a USB multimeter. The S7/S7E will lost about 30-50% of the input current the moment you turn the display on regardless of the charging method. In this case the input should be ~9V/2A or 12V/1.5A (both 18W) in theory. If the charger was pulling via 5V instead there would be a lot more heat, and it might cause some issues if the cable has a higher resistance.

I've thought so. Then how silly of Samsung not to implement it. Since LG's G5, for example, also uses the latest Snapdragon 820 processor and supports Quick Charge 3.0.

It's still quite fast regardless of it being an 'old' standard. Maybe there will be a wya to enable it via root unless there's a hardware controller that is holding it back.
Yes, but what i've gathered 3.0 is more of efficiency over speed. Hopefully, an update would do the trick. Not unless, like you said, it's about a hardware thing...

It is if there's support for that standard. It allows you to ste up/down voltage more granularly so that's why
So I tried the original cable that came with the phone and still the battery drops, even with the screen on and GPS off. I may just have a defective unit. I did browse through some of the reviews on Amazon and it seems there was mixed results with the S7, some people were also having issues with fast charge not working.
According to the first note on the item:
Note: For normal charging use any car USB but for faster charging you will need QC 2.0 Car USB like this one - http://www.amazon.com/dp/B01A54EAHE. You can get 10% off by buying both together and using code MNBXDSUK at checkout.
The only reason why the American version of this handset does not support 3.0 is because the Exynos international equivalent does not support 3.0 so rather than create two sets of charges Samsung decided to make 2.0 the standard and not make the international handset owners feel jealous or a certain kind of way. Remember it's a feature offered by Qualcomm and not Exynos chips.

Well I did buy a QC 2.0 adapter, but maybe it only works with their adapter. I figured any QC 2.0/3.0 adapter would work.

I am looking for a fast wireless car charging dock. I recently purchased this http://tinyurl.com/zowq69q but it does not fast wireless charge my Verizon S7 Edge. I found that while using apps like Waze when the GPS is on the battery was still draining and the phone got very hot.
Looking to see if anyone has had any luck getting fast wireless charging to work with a car dock and the S7.

Can you post pics of the back of the charger? I see it has a ball mount but I'd like to see if that might be removable and Imight be amps compatible or modified for my existing mount

Fast charging is not enabled when the screen is on.

After messing around with the placement of the phone on the charger it seems to now be working. I was able to run waze, bluetooth and stream audio and the battery climbed and held at 100%. Also I noticed the phone did not get as hot. You have to get the phone in just the right place with this charger it seems. I have an older regular wireless charger on my night stand and do no have any issues.
