I am playing with Fastcharge in JB with the Faux Kernel. Here are the specifics of my experiment.
App: Galaxy Nexus Fast Charge (from market). I wish there was a toggle or widget but I'll probably have to wait for AOKP JB.
All charges were done with networking OFF, screen OFF. I would have liked to do a longer experiment but I didn't have time and didn't think extending the experiment time would yield a noticeable difference.
The phone did in fact register as an INTF2 device when I turned on fastcharge, where it shows as a Media Device when it's in USB mode. This is the same as when I had it in ICS (AOKP) with Franco Kernel, which definitely worked (very well).
Phone: Galaxy Nexus LTE
Carrier: Verizon
ROM: Vicious Jelly Bean V5
Kernel: Faux Kernel JB 019
Fastcharge OFF, 10 minutes, USB = 5%
Fastcharge ON, 10 minutes, USB = 9%
I wanted to see if it would also change the voltage/amperage draw from the stock charger that came with the phone.
Fastcharge OFF, 10 minutes, AC = 9%
Fastcharge ON, 10 minutes, AC = 9%
AC was same as expected. I didn't know the kernel had fast charge mode since it doesn't brag this feature but apparently it does.
This is good news considering the poor battery life I've gotten with Vicious JB/Faux Kernel compared to the great life with AOKP ICS/Franco Kernel.

Can a Mod move it please? I never post as you can see. I am not sure where it would belong, as it's more of a Kernel review than anything.
Nexus noob here. What is fastcharge? Does it basically remove any USB connection options and increase the charging speed?
Those guys did compile a GSM version I found it fishing around inside Goo and someplace else. I never flashed it but I did find one (Team Vicious)

1 A = 1 Amp
1 mA = 1 Milliamp (.001 Amps)
A charging AC port can give up to 1.5A through a USB cable, but when connected to a regular port (computer, some chargers), it only provides up to 500mA (0.5A).
What fastcharge does is allow the phone to view the USB connection not as a USB hub or computer, but as a devoted AC charger. This adds much Amperage and vastly improves charging. This allows you to plug into a computer and charge at nearly the same speed as your devoted AC charger. It also helps with car chargers, which for some reason can be stingy.
Some Kernels support this, and many roms have the toggle built in. I started loving it using AOKP, thinking it was BS, but it actually works very well. With AOKP and Franco kernel, I could charge my battery fully from car or USB in an hour, double the time it would take without fastcharge.
Only draw back is you lose the ability to transfer files via that USB connection (the connection to computer shows up as "INTF2" instead of "Media Device." No matter how you feel about it, it's great to have the option to suck some extra battery life, especially considering how crucial my phone is to my existence (I wish I was joking). So now when I'm at my friend's, if he has any device which takes a USB A to USB micro b (what droids use) then I don't need a wall charger and it will have nearly the same effect.
I was testing to see if the custom JB Kernels supported this feature, since I know with ICS and GB, the stock kernels wouldn't allow it. This is very exciting as now AOKP can built in the toggle and don't have to stress about how well it works or whether the majority of kernels support it.

What a spot on post! And, yes, I really like how much AOKP supports, even though I'm not currently using it - who isn't using JB?
Yes, the JB kernels have started to re-implement features as JB is better understood. Franco's is also running great with JB (Official or AOSP).
Please Note: You may forget that you've unleashed the charging potential of whichever connection you're using. Remember, you will need to disable fast charge to use your phone's data connection properly. I'm guilty of forgetting myself from time to time. Nothing like being aggravated at something you did to yourself and can't figure out. lol

Are you talking 3G/4G? I did not know it interferes! Does it interfere even when you're not charging? Have you tried Faux Kernel? I really like Franco but many were saying it conflicted with Vicious. Which Franco are you using? New nightly? I saw that he added JB support but the consensus on the Vicious forum is Faux. It seems alright but not as good as I was getting, battery-wise.
This is such an exciting time to be an Android user with the best (at least most supported) phone!
Any way of getting fast charge setting to stick after a reboot? Seems you have to enable it all the time.

This is a stock kernel for GSM Galaxy Nexus 4.0.3 with the following properties:
Root access with adb (a.k.a. insecure)
Charger is modified to stop charging at 4000mV and > 80%, and start charging again at 3990mV or < 80%.
Rationales:
Stock kernel: I value compatibility and stability. While the various mods and new features are undoubtedly very useful for many people, some of them are not well tested which results in lower stability. That is not to say stock Android is extremely stable (it is not), adding new features on top of which very often increases the likelyhood of crashes.
Limited charging: As a developer, my phone is virtually plugged in the computer all the time. As many of you are aware, leaving the phone charged greatly reduces battery life (Ref). This kernel frees you from having to unplugging and plugging in the phone repeatedly in fear of destroying your precious battery.
Visible differences:
Charging percentage will not increase after the phone is charged to 80% or more.
The phone never reports full charge, even if it's charged while being turned off. That means battery stats can accumulate which, after a while, makes it practically useless as the diagram is too compressed. This is a plus to me as I can see how I manage the battery over time, although I can make an alternate version which reports full charge whenever the phone stops charging under requests.
Perhaps I'm the only one who is paranoid about keeping battery charge between 10-90%, I wouldn't be surprised if no one is interested it this at all.
The kernel can be flashed using Odin or fastboot. If someone wants a CWM-flashable zip let me know.
Cheers.

Glad to know I'm not the only one. When I was using the SGS2 I spent quite a bit of time looking for such mod to no avail. Searching for "android|galaxy nexus limit charging voltage" turned up lots of posts about changing kernel voltage which wasn't what I wanted.
I like to keep the kernel close to stock, but thanks anyway .
Hey, an idea to you devs: what about a apk that schedules the charge limit? for example, if you use to charge your phone at night and you wake up at 7 that app could charge the phone @ 60% and at 6 start charging'till it reaches the 100%
With ezekeel BLX mod it should be easy to schedule modifying the file, but i have no idea on programming nor cron

You can do that with Tasker, it is a bit on the heavy side but saves having another service running in the background while leaves the possibility to do a lot more. I'm not aware of other light-weight but user friendly solutions for managing scripts, perhaps others could chime in.

Not much to speak of tbh. Here is the patch. You can build it from the stock branch 4.0.3_r1 . I changed the compilation flags so it better matches Cortex A9 but I'm sure there are rooms for performance improvements.
GLaDOS kernel has this value configurable as well so aside from being stable, this kernel is worse all around .
I assume you meant 4000 mV, not 4000 mAh? Considering that not even extended batteries I've seen exceed 3500 mAh?

Greetings gentlemen! I've been testing wireless charging with Galaxy Nexus and Nexus 5, and while I like the technology, I'm not comfortable with two side-effects: higher battery temperature, and higher average battery charge voltage. I'd like to work around this by limiting the charge capacity to 80% / 4.0v.
I think the lost battery capacity will work for me because the way I'm using the wireless chargers is keeping the batteries topped up all day. By keeping wireless chargers by the bed and the main work space, the phones hardly ever run down! But this also keeps the battery at 100% constantly. Thus my 5-year-old bright idea to limit the voltage!
What's the state of the art of this problem solution? Should I ask a kernel developer to include https://github.com/Ezekeel/GLaDOS-nexus-s/tree/blx ?
This is for kernel devs only. The patch itself is useless to those who do not/can not compile their own kernel.
I put together this patch for you guys at the request of a few different members here in the nexus S forum who had saw my patch in the gnex forum. 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.
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
Some roms (AOKP) have also implemented toggles.
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
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).
Here you go. Good luck have fun:
http://www.incredikernel.com/wp-con...wnload.php?id=nexus_s_force_fast_charge.patch
Hopefully we will see this implemented into a lot of our kernels around here. It looks pretty sweet. If I knew how to compile kernels I'd be all over it.
Sent from my Nexus S 4G using xda premium
Thanks! I'd like to see this also!
Its been brought to my attention that the AOKP toggle interferes in some way with the widget. I'm going to contact them and see what's up. I think they may be setting the permissions of the fast charge toggle in an undesirable manner.
thank you x 1million!!! I requested this from mathkid about two weeks ago & never heard anything back....I hope this gets implemented now

ahh, thanks for the response I'll write him and thank him for his part in researching this for matrix kernel.
any kernels on the nexus s 4g support fast charge? I cant wait to get this working! Great job!
I've always had a problem of GPS draining my phones battery no matter what ROM I'm running, or what car charger I use, been through about 5 of them. If this helps with that I'm super stoked about this, since it's the only thing that I don't like about my Nexus S.
id love to see how fast this makes charging, considering my phone already charges pretty god damned fast.
•neXus•S4G•ĄØKP•Mïlestøne 4•Aïr Kerneł 3.7•
Does anyone know if this can be ported over to the HP Touchpad?
Anyone have much luck with the fast charge toggle on this kernel? I'm helping my friend who just got a nexus s 4g and setup his touchstone from his palm pre. his phone only detects as USB while on the touchstone even though its a full 1 amp charger. Anyway if he plugs in he gets ac charging obviously. So I had him enable fast charge with this kernel and us NStools. It doesn't seem to work and actually glitches out and charges slower to the point that it never increases even with screen off. It indeed says ac in settings. If he then plugs into regular ac outlet it continues charging slow where it won't increase even a single percent for 20 min. Restoring stock kernel goes back to normal.
Anyone had any luck with fast charge? We're kinda baffled here. I know the nexus s is a slow charging phone already at 750 mA. anyone have any ideas? Thanks.
So I realize this is a bit of an older thread, but since it got bumped anyway...
Isn't this about the same thing as SBC? Meaning, won't this trash your battery very quickly? Fast charging is designed to be something that's only done in emergency situations (which is why people say only to use car chargers in emergency situations) otherwise it will kill your battery. This really shouldn't be something to use in a daily driver kernel.

There are two charge modes: USB and AC. The phone determines the mode by reading the resistance value between the two USB data pins. If the value is zero, the phone charges in AC mode, which draws > 500mA current (eg. wall charging). If the resistance is very high, it charges in USB mode and draws <= 500mA of current (eg. charging from a computer USB port).
What this patch does is it forces the phone into AC mode so that it can draw higher current and charge faster. Hope it clears up your confusion.

That makes a bit more sense, I had my A's and D's crossed there. So basically this just helps speed up the charge if you're charging from a pc then. Gotcha.
From my limited understanding, it's built into the franco kernel, and i need to install an app to enable it as well. I'm on the Sprint Galaxy Nexus running CM9. There a walkthrough or something?
If you're wondering why i need it, my usb car charger is rated at 1.2 amps, and i lost 6% charge every 20 minutes while using navigation today.
buy franco kernel app.
toggle it on.
use.
certain roms have the functionality to enable fast charge but i dont know if it works or not (with franco)
You can also install trinity kernel and enable fast charge with the trinity app in the market.

When you are plugged into your car charger, what does it detect in the battery menu, usb or AC? Reason I ask is my car charger is 1.3 amp and it reads as AC when plugged in and I can't drain it while plugged in.
I saw Fastcharge in the tweaks section of AOKP. Franco's kernel is the bees knees in terms of battery life and screen on time. That **** goes H A R D
yeah im using francos now. trinity was like, more than 20% battery per hour. nuts. dat gpu overclock. i have some app that's wakelocking me though, cant figure out which one.

Many Kernels offer this. Most have command line options as well. Franco, Trinity, and GladOS all have apps on the market that make it simple to toggle.
Hello everybody,
I'm planning a quite long road trip in some days, and noticed recently that my battery drains "quickly" using the GPS (with Sygic app) when the phone is plugged.
The route will be something around 12h, and I can clearly see that the phone will not stand this long (tried using Sygic in simulation mode).
It happens also when using some apps like i-display, the phone won't last forever when plugged.
Is there any thing I can do to prevent this drain, like disabling/closing apps (which ones / how to detect ? method ? any tools ?), or even changing my rom (don't know if the rom can be the cause).
I've also seen this post : http://forum.xda-developers.com/showthread.php?t=2512421 . Can it be related ?
I'm running on Resurrection Remix 5.5.7
For closing apps, I tried force closing facebook/twitter... in the application setting, but they always reappear.
Thanks for help.
you can turn off screen and set it to give voice guide or turn off screen on long, straight part of the trip.
usb charger in car is about 5 times less powerful than standard wall charger.
the only thing you can do is get car inverter to plug normal charger
I'm pretty sure that I did not have this issue when I was using my phone as a GPS a while ago, when I had a Samsung based rom (dito note).
But it sounds strange that my current rom drains more than the one with all Samsung additions, no ? (Even though I noticed a small loss in battery life ... should I test an other rom ?)
Or maybe the battery is getting old ?
I did my "simulation" test while plugged in a USB port of my desktop, how does it compare to a car charger ?
Sent from my GT-N7100 using XDA Free mobile app
Even I get less power, even while using a wall charger on a cm ROM, to the extent that the phone discharges when if is plugged in even at 30% brightness. This is even after using Agni kernel (and without also). I downloaded a free app from the play store "galaxy charging current" from the play store and the app helped me figure out that I get different charging rates with charger and cable combinations. But even then the best I have been able to get is 1400 ma( that too not consistently) after using a new cable. Maybe the charging port itself has become faulty due to accumulation of carbon(don't know to to clean it without risk of damaging it!)
If it helps, I can confirm that this also happens on a full stock 4.4.2 Samsung ROM. On a 1A output, with 100% brightness, GPS and Data Connection, the battery continues to drain instead of charge. Haven't tried with only 30% brightness and GPS, though.
I did a quick test this evening with a new rom : android 4.4.4 Eclipse V4 , not installed many apps, had Sygic running a simulation, gps active and no data or wifi (like I would probably do while driving), charging on the usb front port of my desktop :no battery loss, the battery level fluctuated between 77 an 78% for 4 hours ... seems good.
I still try to understand where this difference comes from : touchwizz rom that better handles the stylus digitizer ? Android 4.x consumes less power ? Because I had less apps (so maybe less background apps) ? Samsung touchwizz has less power consumption then google now / cyanogen trebuchet ?
I like the idea to have android 5.x (latest version an feature), but this difference in battery time disappoints me a bit.
I'm no expert, but I suppose it all comes down to ROM optimisation. After all, you are comparing something made by a little team (or even by a single developer!) to something made by one of largest (if not the largest) smartphone makers! And I know that it is dissapointing to go from 6,5 hours screen on time (on stock) to 4 hours, but we can't have them all, right?
I totally agree with the point, but in fact, small team already do great jobs compared to the smartphones makers, just look at all the custom TW roms for the Note 2 : tweak, better battery, galaxy note 3&4 and s 4&5 features ...
What I don't understand, is why a rom like this seems to drain more energy than an android 5.x "stock" rom (shouldn't android 5.x have a better battery life btw, compared to 4.x ?).
Get a decent charger and a good cable. 2A charger is the minimum, and forget about cheap Chinese cables.
I had the same issues with both cheap chargers and expensive Nokia "2.1A" car charger (which I guess was no more than 1A in reality). Now I installed this in my car and forgot about these issues:
"DC 9V-40V 4 USB port 12 24V to 5V mobile phone pad Step Down DC 5V 5A Car Charger Power Supply" on Aliexpress (sorry, cant post links)
Busted my Moto, had to fall back to my trusty E980...
I can't use CM based ROMs because I rely heavily on BT and camera and both are a bit wonky in CM...
I've got a setup right now that I'm happy with (Henry Pham's excellent ROM) + Xposed, but it still charges pretty slow. I'm using a powerful charger- an Aukey 40W 8AMP (2.4a per port) and decent USB cables... my LG still takes far longer than my other devices to charge.
So, is there a 5.0.x ROM that does NOT charge super slow? Or is there a kernel or patch I don't know about?
You might have to enable quick charging. In my SlimLP the option is in Kernel Adiutor app, in battery settings. Before that, the phone could take only 500mA, but with that enabled - 1500mA.
How old is your battery? That can contribute...
this rom charges to fast, the faster one i've knew but the battery drains as fast as charges, is there a fix for this problem?
@elmanolette
Yes, there is.
