I have been using my Note II to connect to my appradio 2 head unit in my car. I have a 2.1amp charger in there and it is connected via a microusb cable but the phone is clearly not receiving the same rate of charge as the wall charger. Even while charging and with the screen completely dimmed it drains the battery quite significantly, especially when streaming music or using navigation.
I am running the perseus kernel and have STweaks and want to know if it is safe to raise the SDP Input and/or Charge Current rates from 475mA to something around 1800 or 1700 mA in the Power tab? I am assuming this is the bottleneck preventing my phone from charging fast in my car as I have tried a few different chargers.
Any info on this would be greatly appreciated
So I did a little testing and it seems both my chargers are working at full charge when not plugged directly in to the phone according to the galaxy charging current. The problem is in order to use the head unit in my car the charge must go through the MHL adapter. Will changing the SDP Charge Current setting in STweaks fix the bottleneck through the adapter? I would try it but I don't want to break my adapter or phone.
EDIT: Changed the SDP Charge setting to max and it is working great in my car with the MHL adapter and even on my computer

I need help... while i am charging in car with AC mode charging, and running gps navigation, it lost charge. I could understand of it is the case in usb mode but why ac mode will also have the problem?
My charger has 2ports, 1 is 1A and another is 2.1A rating.
Please help, i am in a new country and i couldn't do long with gps losing charge. I am on DXELK1 rom
Try another charger and lead, your existing one may not be delivering the rated current. There is also a thread about the S3 deciding to reduce the charging current, with a fix to set it back to 1000mA - search here in Q&A.
I tried different car charger, still the same even those are charged at AC mode. I couldn't find the thread abt any tweak, any hints on keywords?
Probably GPS is draining more than can be supplied, so grab a kernel that has charging limit override and up the max to 1200mA
Usually due to battery temperature. Once it exceeds 45-ish degrees due to sunlight/charging/ambient and so on, the charge rate is reduced considerably to reduce the chance of battery degradation/damage. In other words, it is a safety feature that should never be overridden.
Hi, I'm browsing this forum section but i can't find something the answer to this 2 questions:
1- Which is the best charger for home i can get (i want play and looking movies without getting the message "your device is charging slower then consumption...")
2-There is also a charger for auto that charge or keep battery lever even with gps+bluetooth+navi+music aux on?

1 - I use a DK30 dock at home. charges very quick (using default wall AC unit)
Any wall charger that has 2000 mAh and 5-6 volts will be fine.
The mag connector is supposed to charge faster than microUSB. Haven't tested that, but it certainly saves capping and uncapping the microUSB tab.
2 - As long as you have 2000 mAh going into your device from your car, you'll be fine. it should still charge your device. It will depend on what cigarette plug your have.
Hi there,
I'm searching for two days, but can't find any complex explanation of charging current.
Someone said me, Sammy made an limit to 650mA, and there is a lot of posts about this.
My ROM is SlimKat 4.4, and there isn't fast charge option in this ROM, so probably(?) I'm using only 500mA regardless of which charger I'm using. Is this right?
Somewhere I read original Samsung car charger have some special resistors inside in order to charging faster?
Any explanation, links to existing threads are welcome.
I'm using navigation software in my phone and during navigation battery goes down...
I made some tests, and my wall charger (Samsung) is detected as AC, also car charger (unoriginal) also is AC.
I wasn't sure of this myself but when I flashed Dorimanx kernel, I could see in Stweaks that we could manipulate the charging current (with an upper limit of 650mA). I m sure the same can be tweaked by any kernel.
The upper limit is there to protect the hardware from overheating. The upper limit on USB charging its 500mA which is again to protect the hardware at the time of USB connection. With stweaks we can increase the USB charging current limit atleast.
Noticed fast charging option in C-rom, you can visit their thread and ask questions about it.
Hello everyone,
I was wondering if there is a way to increase the charge rate while connected to an MHL adapter.
I have a 2014 Civic Si that literally has an HDMI input for the head unit.
I bought an MHL adapter and it works very well other than a safety limitation that stops screen mirroring while driving, and the fact that even if I am just using it to get the best quality audio into my head unit with the screen turned off, the MHL adapter uses more current than it returns to the phone, resulting in battery loss.
I have the usb power connected to a 2 amp 12v charger that works fantastic when it is just connected with a regular micro usb cable so I know its not the charger.
I have found some evidence that there is a mod that can basically tell the phone that it is connected via AC to take more current.
Would be awesome if someone could provide this, or another solution to this problem. I imagine there are a lot of people like me out there who like to use MHL adapters but don't want their battery to die.
Thanks
Check the quality of the cord. If it's some cheapo one from like eBay or something that may be the problem.
I've found that some of my older degraded cords won't charge the phone while I'm using it.
Also if you roll/folded the cord up sometimes it can pinch it just right to not supply the right charging power.

To be clear it does show that it is charging (via USB) but its using more current than its getting thus end result is the drain.
It could very well be the cable - hence why I am asking if anyone can recommend a tried and tested solution of MHL + charge that actually charges it quickly.
Thanks,

I researched before posting this. I'm a Nexus 4 user fixing my fiancé's sgs3. The phone started charging at 100mA a few days ago. So I flashed temasek and boeffla to ignore the detection problem. Now, however, the phone detects the AC charger as USB. I've tried a different battery and 2 other chargers.
Also, to get around this, I used boeffla's kernel settings app to increase the Amps when charging from usb to 1000mA and the charging current increased on the Galaxy Charging lite.
However, if i use the phone while charging, the battery percentage drops. I need a way to fix the USB/AC detection problem. I can't keep the 1000mA rate on USB.
Any help?
Really? Nobody??
Try checking "ignore unstable charging power" and "disable charger margin detection ".
Set the USB current to 1000mA instead 475mA by default.
All that is done in Boeffla config.
If still the same, try with other USB cable.
If it keeps failing, I'd say the USB connector is damaged, common on these phones (and all other phones using microUSB)
Thanks for the reply. I've already tried all of that. It seems that when I plug the phone into the AC charger, sometimes the cable is detected as USB and it charges at 500mA (though set to 1000) and sometimes as AC. So what could the problem be here?
This forum is much more helpful than what I expected
