[Q] Note 4 Car Charging?

Hey guys,
I just plugged my note 4 into my car charger (anker charger, oem note 4 cable) and couldn't get it to charge. It charges my note 3 no problem.
I also have no problems charging my note 4 with wall chargers.
Any help?

I've got the "Anker® 18W / 3.6A Car Charger with Built-in Micro USB Cord for Android" and it's actually CHARGING my Note 4 when using GPS navigation and playing music! My Note 2 wouldn't charge, but it would hold charge under the same conditions.
What model charger are you using?

I actually can't find it on the charger itself or even Amazon. It's relatively new, I thought it was a 2.0/2.1 amp charger (2x USB). Definitely Anker though.

Are you using both usb's at the same time? If so, it's splitting the power, so you'll get a slow charge.

Sorry, I should have specified - the only thing plugged into the charger is my Note 4.
Shoot, maybe I just need to grab another charger. Thought I made a good decision with that Anker.
Thanks for your reply by the way

If you get the one I listed, it works for sure. Great charger and it's been the only one my wife hasn't been able to destroy. :laugh:

Will the car charger also do the 50% in 30min charging ?

Hmm.. this mentions rapid charging, I wonder if it's as fast as the wall charger
http://www.samsung.com/us/mobile/cell-phones-accessories/ECA-U21CBEBXAR

The only chargers that work with the new fast charging technology are ones that are purpose built and have the ability to switch between 9V and 5V,they are quite uncommon.

I have this charger http://www.amazon.com/gp/product/B00D82O68Y/ref=oh_aui_detailpage_o03_s00?ie=UTF8&psc=1
and it charges my note 4 while running Waze and tethering my Radar Detector via Bluetooth (which also uses GPS)....and it charges my wife's S5 at the same time

Using an afer market 2.1a charger and an S3 cable, charges just fine.

I believe Samsung has stated it's a 9v charger instead of the conventional 5v charger.

Did some more research and found this:
http://www.incipio.com/chargers/car-chargers/quick-charge-2-0-single-port-usb-charger.html#
From the Engadget review, "I clarified with Samsung that it chose a proprietary solution instead of licensing Qualcomm's QuickCharge tech, but it insisted that you could still use QuickCharge 2.0-compatible chargers to achieve the same results."
Also from http://www.samsung.com/sa_en/support/skp/faq/1063730?CID=AFL-hq-mul-0813-11000170
[FAQs] Smart Phone : Galaxy Note 4- To use fast charging, what kind of charger should be used?
Fast charging uses battery charging technology that charges the
battery faster by increasing the charging power. The Galaxy Note 4
device supports Samsung’s Adaptive Fast Charging feature and
Qualcomm Quick Charge 2.0.
To use Fast charging on your device, connect it to a battery charger
that supports Adaptive Fast Charging or Quick Charge 2.0.

Fast charging with 2A charger

Hi
I am planning to buy this phone.
Can anybody confirm if faster charging is possible with a 2A non stock charger? How much time does it take to reach 100 percent?
Sent from my iPhone using Tapatalk

The phone doesn't have fast charge
For me, it takes 1h 30m to charge from 0% to 100%

Absolutely correct, the phone doesn't have FAST/QUICK charger technology...
However a higher ampere charger like 2A could still charge a phone faster, hence my query above
Are you sure it takes 90 minutes to fully charge with stock 1A charger as mathematically it's not possible
3000mAH/1000mA=3 hours
Or
3000mAH/1.5H=2000mA or 2A
Pehaps you are using a higher capacity charger? That would explain it...
Sent from my iPhone using Tapatalk

The time of charging with 2A is the same using a original charger with 1A. The limit is inside at the circuit control of charge.

This is the 3rd comment I have seen from a user confirming 1A is the max phone can utilise
Such a shame as I think this is the only real flaw with this phone, otherwise it's a great device...
Sent from my SM-G930F using Tapatalk

Yes, you have right.
We can put a 10 A capability charger at our device, but charge control circuit is doing his job and let device charging with 1 A max, even if is there 10 A disposable....
Maybe with some command in hidden menu or with some customized firmware is a way to override this limitation.
(At LG 4X HD is in hidden menu a command that enable fast charging).

Where exactly does one have to change what in the root directory?
I want to test this time.

I doubt we will be able to find any such software hack to allow fast charging.
There just isn't enough development going on for this phone for anyone to discover and share such information
https://www.androidpit.com/huawei-p9-lite-review
Above review was found by another user on this forum where it's mentioned that phone supports 10W (5V×2A)
So this is what I am hoping is correct and is verified by someone who owns the phone already

That would be really very nice, I would be really happy ).

Maybe fast charge working with another type of charger: Huawei 9V2A Quick Charge Travel Charger
Instead of 5V1A(5W) or 5V2A(10W) with 9V2A(18W) charger, the charge circuit control will sense 9V instead of 5V and maybe switch to fast charge...

2 Amp charger are only needed if you are using a 2 or 3 meter USB wire.

I dont think so.... the options you mentioned actually mean QC 2.0 technology which we know for sure isn't available in P9 lite
There are few mentions of phone supporting 5Vx2A online; one such link shared by me in earlier post...

The P9 Lite doesnt support any sort of fast charging. The ability of a phone to charge faster depends on it's hardware and the use of a fast charger. However, with a 2A charger, it slightly decreases charging time since the phone pulls approximately 1050mA. Be careful not to use a charger thats higher than 5V as it will fry your circuitry.

Where did you get this 1050mA spec, did u measure it yourself? This could be true as well, as fast charging is not observed by anyone until now except few online sources which state otherwise...
The part about damaging phone is inaccurate as QC 2.0 or 3.0 chargers are reverse compatible with old devices which support 5V only, the phone and charger never switch to 9V/12V/20V mode as the technology isn't there...

I did measure it myself with the aid of a friend. By the way, I was referring to a standard 9V/12V charger, not the QC charger.
According to my knowledge, the voltage is like a gateway to your phone, your phone pulls the current. Hence, if you use a standard charger with higher than 5V, you'll most definitely burn your circuitry. BUT....if you use a 5V charger with an abnormally high amperage, the phone will only pull the current it needs.

Great that you actually measured it, I am assuming using an external device...
That would confirm it without doubt that online reports are incorrect and phone can't charge above appx 1A

So just a quick question.
This means that for a phone to be able to pull 2A, is not just software control?
It means that the hardware has to support the ability?

I believe that is true. Although, most fast chargers (like the samsung one) only supply 1.67A at a higher voltage, normally 9V. This combination increases the output wattage of the charger....Like i said on my earlier post, the voltage is the gateway to the phone while the phone pulls the amperage.

Any issues with using Samsung USB C cables/chargers on V20?

With all the returns and obtaining of phones I've amassed a nice stockpile of Samsung fast chargers and a few Samsung USB C cables(and adapters).
I've read before that USB C allows for non standard use of cables by manufacturers so I'm wondering if anyone has tried or knows if it will be an issue using the said chargers/cables (yes I know the Samsung chargers are only QC 2.0 spec).
I have a QC 3.0 car charger I got from Aukey during a sale. I have some Aukey USB A to USB C cables too that work fine with my Note 7 too.
Trying to see if I need to slowly replace my Samsung chargers with official QC 3.0 wall chargers (will need at least 2)

Here at work I am using my Note 7 charger setup. Left LG flat cable at home.

It's adaptive fast charger and does either 5.0v @ 2A or 9.0v @ 1.67A so 10w or 15w respectively

All QC are backwards compatible. QC 3 will know you are using QC 2 and charge at the rate of QC 2. If you use a QC 3 charger and have a QC 2 device the device will only draw QC 2. So you have nothing to worry about as long as they are QC compliant

LOL i was about to say. Go to Tmobile now and tell them so that they can give you a new one. Because despite i have 35 apps up and running, and i have done a lot today, my phone gets charged in about 1 hour and 15 minutes (pretty decent if you ask me)

9.0v = 1.8; & 5.0v = 1.8a

I had the same thing happen to me the first time I plugged it in...
That said, I found my quick charge 2.0 charger charges it faster than the charger in the box, so I am thinking of buying an official 3.0 quick charger.

That stock charger doesn't look like it's variable voltage that qc3 requires

I know. Im using my own charger with 5v and 2 amps. And it charges very fast with it. With the other it does charges fast. But not as fast as this one

The supplied charger is like a QC1.0 version, it's not even a QC2.0, it doesn't have the 12V, this is the same with the V10 and the G5 which is supplied with the same charger.

Theoretically speaking I charge the other battery in the spare battery charging dock. So when I swap the dead battery out it only takes 30 seconds or so to have a full charge on my phone. No more tethering my phone to the wall.

I have an Anker QC 3.0 charger and last night, it charged my V20 from 6% to 100% in about 1 hour.
Sent from my LG-H918 using Tapatalk

Measured at the wall, my OEM charger refused to charge over 2.7 WATTS - 2 point 7 - when the battery was at 15%... what the eff? Not that I care, because the charger is junk anyway, but sheesh! Makes no sense...
Also, the charge current drastically drops any time the screen is on from what I am seeing, as pictured below.
Also what makes no sense, and 2 reviewers on Amazon commented the same issue, Anker's PowerPort +1 Type C QC 3.0 charger doesn't work with this phone. I couldn't get it to go over 12 watts with the screen off even though I tried 4 different cables (Anker, i-Orange, i-Rainy, OEM Pixel XL cable). Interestingly, the Pixel XL OEM charger peaked at 19.2 watts! Really interesting actually... don't know how it's doing it, since it's USB PD, but it does have the proper voltages. It's charging the phone pretty damn quick. Even at 68%, it's pulling 14 watts right now as I type.

POWERBANK for S7 EDGE with FAST ADAPTIVE CHARGING SPEED

Hi all,
I want to buy min 20000mAh capacity powerbank for me and my wife's S7 Edge phones and capable of fast charging both S7 Edges simultaneously.
I already bought Anker Powercore Elite 20000mAh ( https://www.anker.com/products/variant/PowerCore-Elite-20000mAh/A1273011 ) but, it does not charge them with fast charging !
I tried many cables (all of them orginal and official) but the results are the same: "cable charging" !
So, can anyone suggest me 20000+ powerbank with fast adaptive charging for S7 edge for sure, even better if real user with real experience?

Also, it is surprising that Xiaomi can support fast charge for Samsung S7 Edge but Anker can't !
Mine was Anker Powercore Elite 20000 and had 3 usb output, total 6A. If 2 phones charge at the the same time, 3A for each.But still says "cable charging" :/

Are u sure the Anker that u bought is fast charging support ? Try with different cables bro. I will check for a 20000 mah MI PB and give u link

Your Anker powerbank doesn't support fast charge.
Samsung fast charge work by increase voltage from 5V to 9V but lower current from 2.0A to 1.67A, which give the total power of 15W (9V×1.67A) up from 10W (5V×2.0A)
So for powerbank to support fast charge, it must be able to output 9V.
