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.

I went with trinity cause i hear more people raving about it. What do you recommend as far as settings go? I have the vibration maxed out, not sure what to do with the dirty ratios. Obviously fast charge is on now. Someone mentioned they had a 5 hour screen time with this kernel

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.
I had been using CM7 for a while, and had great experience with it's battery life, sometimes lasting up to 3 days on a single charge.
But some things didn't work well, such as the barcode scanner, camera working eraticly, and the lack of PS Pocket.
So I get back to a stock based ROM, Xperia NXT. It's good on battery life, but not nearly as good as CM7.
I'm looking for something different. Just looking for opinions. One thing to note, DoomKernel SUCKS on my phone. Any time I install it, the battery is sucked dry in hours for some weird reason.
Any ideas?

IMHO AOKP (milestone 6) with Lupus#4-cfs clocked @ 1.3ghz with smartassV2 gives me great battery life. I can get 36 hours with moderate usage. full day with what I consider heavy usage.
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.
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 ?

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)
I recently upgrade my stock Nexus 5X to AICP (Custom Rom based on LOS) and everything that came with that (unlocking, TWRP, updating kernel, rooting with Magisk) to "celebrate" the end of security updates for the Nexus 5X.
But I've noticed that when I listen to an audiobook and play a game WHILE IT IS PLUGGED IN, the battery will slowly be DRAINING. For some reason the charging can't keep up with that load anymore, when in the past it'd slowly charge under that same combination of apps.
Could it be slower charging? Or the system using the battery less efficiently? How can I tell? Could it be quick charging no longer works under the new ROM? I think it might be that this new ROM is just more draining, but I can't really tell or know what to look for. Have others experienced this and can maybe point me to something that works better like the stock OS used to?
