Very slow charging when in car, says USB

When im using my nexus 5 in a car, or when powered form anything other than the official charger it takes for ever to charge.
If left overnight this isn't a problem, however when in a car charging from the lighter socket my nexus looses charge when streaming audio and using the gps.
The only thing ive noticed is that it appears to have three charge modes:
Wireless - charges reasonably fast
AC charges fast, but only appears on the standard charger with the standard lead
and USB when it charges slowly, or even looses charge.
any way to enable to AC mode when its connected to another ( ie third party ) charger?

it would depend where you plug in. via wall charger will be ac, via any other place itll be usb. and when usb, it will charge much slower than with a wall outlet(ac). that is normal and how its supposed to work. and if you are using a 3rd party charger, make sure it has the same voltage that the default charger has, or it will charge slower.

third party charger, mains output 5v dc, 2.1 amp, nexus charges slowly says it's usb. in car adaptor 1.5amp, 5 volt slow charge.
all checked with multimeter for output values etc.

Maybe you are using a thin cable?

Yup, it'll be the cable

I agree that it's probably due to the cable.
One thing that I've noticed (especially with a couple of my LG devices that have fast charge and it's more noticeable) is that a thicker data sync cable works better than a standard charge only cable, which are usually thin.
You could also try a kernel that has USB fast charge.

S5 car charger that actually charges?

Hi all,
I have a couple of micro usb car chargers and when I was using a Navigator app whilst driving somewhere my battery just died despite the charger being plugged in and showing as charging?
I bought another charger off ebay which is a usb car socket with a genuine Samsung micro usb cable. It shows as 1A output and I plugged my phone in to charge at 1% with google maps running, half an hour later it had only gone up to 2%?
What I did previously was plug the 3 pin mains charger into a 240V inverter plugged into the cigaretter lighter socket and that actually charged the phone. Any ideas why the car chargers won't charge it, does anyone know of a car charger that actually will charge the S5?

buy yourself 4.8A dual usb car charger (2.4A per port).

If your battery goes above the 42°C the Kernell stops charging; the consumption of the phone can be up to 700mAh, so with 1A the charge must increase in about 5% in half an hour. with a 2A charger the kernell will accept another 800mAh as much, so you can fully charge your phone in more than three hours, (whe in a fully use) but always with abattery temperature lower than 42°C

I personally use the Anker Qualcomm 2.0 car charger, no problems, I like how fast it charges even if I am heavily using it (unlike other chargers I have owned)

Excellent,thanks both. I got hold of a 2.1a charger which seems to be doing the job well at the moment. Interesting thing about the battery as I have felt it get very warm at times, not always when charging though.

I bought this [Quick Charge 2.0 Car Charger]CHOE 30W (with Most Powerful QC 2.0 Port) Dual USB Car Charger with 22AWG 3.9FT Micro USB Cable(White)
Use coupon code 88PKZDLL on checkout to save $5.45 making it only $10
actually works

I can really recommend this one: Aukey® Kfz Ladegerät 4.8A Dual Port Autoladegerät mini Car Charger, 2.4A+2.4A（4.8A max）dual Ausgänge für iPhone, iPad, Tablets, Smartphone, Navi u.a. USB-Geräte (4.8A dual Port mini Schwarz)
(Can't post the URL because of anti-spam bull****. Just search for that strink on amazon.de)
It's powerfull enough to charge a S5 and a S5 mini for example.

I have a genuine at&t 2.1 AMP car charger for my SGS5 and I never had any problems with it. It also has an extra USB port so you can charge two devices at a time (the 2 amps split to 1 amp for each device).

USB-A to USB-C won't fast charge your 6P. You need a USB-C to USB-C cable and a USB-C charger capable of fast charging at 5V/3A.
I suggest you take a look at Benson Leung (engineer at Google) on Google+ or over at Amazon for an approved charger and cable.
I personnally have the Choetech USB-C charger and the USB-C to USB-C cable for travelling and it works perfectly.

It says fast charging if charging over 2A I believe. This is "fast" charging, but USB-A only goes up to 2.4A. Full USB C to USB C will allow 3A of charging speed. You shouldn't have bought that charger or cable.
Get a Type C charger and Type C to C cable. Anker makes good, stylish cables as well.

Mine only says charging at 2.4A. I only achieve fast charging at 3A. It's a 20-30 mins difference to full charge. Not a big deal.

Weird charging behavior - New cable

I just received an Aukey USB cable 2m in length from amazon after reading many positive reviews. For some reason when i plug in(Samsung Note 2 and Sony 1.5A adapter), the charging bolt comes for about 2seconds(measured 1900ma) and goes off. I keep it aside for about another 2~3mins, the charge bolt comes(for 2s) and goes off again - this goes on a loop. I tried connecting to another AC adapter(Sony 2A CP-AD2) with the Aukey cable, but experience the same issue. I tried connecting it with my brothers phone(being a Samsung Note 3), the charge bolt does show up(measuring 1800ma) but the charge level drained from 4% to 1% while using for about 5mins while plugged(like as though it wasn't plugged in).
Now comes the weirder part, i connect my Note2 with the same cable to my macbook, to my surprise the phone does charge(460ma) as well as data transfer too is possible. The charging is true this time because i didnt notice a drop in percentage. This has left me very confused on where the problem lies. Has this occurred to anyone?
ps. i have seen people on the comments say the cable works perfectly with an Aukey Charger. I dont suppose a sony charger would interfere with a third party cable

Hello,
We speak about the USB Typ C cables right? I also got the 5 cable bundle from Aukey at amazon (3x 1m, 1x 2m, 1x 0,3m). So far the cables work perfectly, I use one with an Nexus 5X charger, one with an HTC charger and one with a car charging adapter (all with the 1m cables). When I'm at home I can try to charge my phone with the 2m cable to check whether it shows the same behaviour as yours
Edit: checked also the 2m cable, phone charges normaly, did you get a bad cable?

Cable that truly fast charges from 0% to 100% at 78min?

Hello
I need to replace the usb cable that connects to the original charger that comes along with the phone.
There are cables out there that are sold as original Samsung cables but don't fast charge the phone in 78 minutes from 0% to 100% even if they are connected to the original charger.
So is there a cable that truly fast charges the phone exactly like the original in 78 minutes?

The cable has nothing to do with it. Use a regular functioning USB cable with a Quick Charge 3.0 charger (such as the Samsung charger with the lightning bolt on it, or the Anker Quick Charge series) and the phone negotiates with the charger. The cable is just a medium. I prefer the Anker PowerLine+ cables for their durability; the stock Samsung cables are fragile.

Τhanks a lot socal87. I was thinking the same thing as you but i got worried from negatives reviews in amazon ( saying that the cable they bought wasn't fast charging the phone).
Also in another well known forum, there were comments like the following :
"Samsung plays with the extra pins on the microUSB connector to tell the phone different things - like USB/AC charge, or fast/normal charge."
"My troubleshooting with 7 different cables showed me that the the very new Samsung charger cables that came with non-fast-charging phones did not fast charge when connected to the fast charger adapter portion. It appears that the cable does in fact matter. I tried many combinations of cables and adapters during my testing."
I will buy an Anker cable as you suggested. In another forum i read than indeed the Anker cables do the job right with fast charging. Thanks again.

Of course the cable has to do with the charging of the phone, try charging with a cheap $2 cable from eBay and try yourself.
Best cables (that i use) are from Monoprice, get their Ferrite core one, best cable out there, charges my phone to 90% in around 70-80 minutes with normal charging (no Fast Charging)

Try any original cable from HTC Nokia Samsung Motorola you can find one in repair place ask him for used original one or new...

Τhank you all for your suggestions. I have already ordered an Anker powerline cable from Amazon and i face any problem i ll buy one of those you suggested.

Blitzwolf does be more better distance charge of 1m at Maximum average 2,1-2,4A of 9V/2A or 5V/3A

You can find Samsung original cable in any official service. I have paid 5$ for a 2m long cable and it takes about 1.h20m to charge from 1%
