I bought an Xtreme 2.1 amp car charger but I noticed once charged my note 3 gets hot (110 F when I unplugged it).
Would using the oem cable be likely to help? The Motorola USB to micro plug cable I used did not cause overheating on an ac plug.
Can you suggest a car charger that works well without causing the phone to get hot?

Hi I am using this for car charging. USB outpu is coded for samsung so it can charge with full capacity (as wall charger)
http://dx.com/p/dual-usb-3-1a-car-c...-mini-samsung-p1000-black-171789#.UuV45NJajIU
Electronics in it has very high coversition efficiency (%95 effc. 14V to 5V conversition) so it will not heat up.
Two independent ports one 1A and other 2.1A
Wish helps,

You seem to know a lot about electronics. Does the cable I use matter or is the charger primarily responsible for overheating?

1- if charger has low efficiency the loosed energy will turn to heat on charger. Generally efficiency is near 80% and it translate to near 2~3watt energy loose on full power. It will heat this little chargers very fast.
2- if the cable is too thin or connectors oxided, power loose on cable will heat cable, charger also phone. If the problem is cable charge time will decrease when cable heated. So if your charge time is ok, problem is dc-dc convertion efficiency.
You mention low efficiency getting charger hot. It wasn't., nor was the cable. Only the phone was hot.

chargers output voltage and ripple must be measured.
Voltage higher than 5.5V or voltage ripple can cause this. Charger voltage can ripple from 4V to 6V and you can only measure 5V avarage voltage with standart multimeters. Be carefull and do not use that charger.
Im using this one from Verizon. It works very well and has a handy led light

I have a one amp usb charger that cant seem to charge the Note while streaming audio over LTE, HSPA, or locally with beyond pod. With the screen off, i lose a percent every five to ten minutes while streaming audio through winamp, flash via the stocm browser, or beyondpod, and the note doesnt lose power while playing local media through beyondpod or winamp...but it doesnt charge either.
And when im charging via he wall adapter and im using the devjce it charges extremely slowly...this is a slow chargibg device, but really, cant i even charge it in the car while playing local audio? Can a usb device pull over a amp from a car charger? It was hard enough even finding a one amp adapter at brick and mortar stores. Are there more powerful adapters? Can the GNote pull more than an amp? Whats does the wall adapter pull?
What adapters are you guys using? Any reccomendations?

Nav, Pandora and a 5.3" HD screen running, probably just exceed the phone's recharge rate. I have found the very best recharging combo, while the phone is under load, to be the Moto charger and....wait for it....a cheap Hyperion 2600mah replacement battery on Amazon! I have no clue why.
The oem Samsung battery barely creeps upward while running nav and mp3's at the same time at about 5-10% an hour. Still beats my previous discharging.
But inadvertently, I found my backup Hyperion batt charges at a pretty quick pace with the exact same load. I haven't measured it yet, but it is at least twice as fast. Let the geniuses figure this one out, because it makes no sense to me.
My Samsung Galaxy Note™ is smarter than your Honor Student.
Using the moto charger, I started with a full battery, watched 70 minutes of streaming video in the Plex app this morning -- with a mix of 4G/LTE -- and unplugged with a full 100% charge at the end of that 70 minutes. Good stuff!
Just drove home today streaming Pandora in the car for thirty minutes with brightness on auto and Bluetooth audio to the car radio on my OEM Samsung genuine car dock. I was at 95% and when I got home I was 100.

Already I have gone through 3 car chargers for my note 2 cheap ones and a Samsung charger none work well charging. The best one was the OEM Samsung but there must be a broken wire in there cause it charges then stops i move the cord and it works again. So I am looking for another car charger that actually charges and wont break in a month. Please post your opinions and links to the charger you refer (with best price of course ).

This really is the best option (but I WOULD NOT SHORT THE CABLE). I downloaded an app that measures incoming amps and tried several car chargers. Most of them only output .5 amps. You are better off buying a car charger for the iPad (2.1 amps) or modding a normal charger as suggested and using any data cable.
I use a modded Power-Bolt charger with a retractable USB cable. This combination takes up the least amount of space and rapid charges my phone even if I'm using Google Navigation at the same time.
The Note comes with a normal USB cable and a shorted wall charger. The Note knows to rapid charge when it senses the short.
Rather than butchering either of my Kensington PowerBolts ......yet I chose to use Current Widget to measure output of basic Samsung microUsb car charger. Depending on battery level it registered over .9A at times yet on 2 hour ride last week w/ Google Maps it wasn't enough. I use ProClip device mounts, but for the hell of it bought Samsung's car mount today to see output of its included charger. Top measurement on 80%+ battery was 1.092A ?????? I'll let battery drain down and report back....

If you do decide to butcher your PowerBolt, you won't be dissappointed. I'm getting over 1 amp now regardless of battery life or Navigation. It's a bit tricky with the PowerBolt Duo, but you cannot tell it's been modded.
You have to peel off the top sticker, then unscrew the top. I did not have a torx driver that was small enough, so I just drilled out the torx screws. Then you remove the top, disassemble the charger, and solder the two inner USB leads on the 1 amp side only. Reassemble the charger, add a drop of glue to attach the top, and put the sticker back on. Now I can charge my iPad3 and my Galaxy Note at the same time, while they're running.
I own both the single 2.1A port and the Duo 3.1A. What are you getting out of 2.1 ports? I don't remember getting over .992A with it. Am I wrong to expect closer to 2.1A?
I didn't look under decal yet, but own mini torx set.
Even though I own ProClip mount I bought Samsung Car Dock on sale at CompUsa to see what charging output the included charger produced and Current Widget measured 1.059A while battery was at 73%. It's the first time I remember getting over 1.0A
In about two hours of charging I went from 8% to 41%. Is anyone else experienceing this issue? I'm using all the cords and plugs given to me for the wall.
I don't have the SGS3 (yet), but my guess is that the battery is so large it takes longer to charge. Keep in mind that it's a 2100MaH battery. Depending on the power that the charger puts out, it could take longer to charge this battery than another phone.
Mine charges fairly quick with stock items.

Monoprice sells a 2.1 amp 4 usb wall charger as well but it is not as cheap nor do they have free shipping *although atleast in CA I can get a flat rate of 25lbs and under for ~$5 shipping.*
I'm surprised no one has posted the correct answer to this yet. The wall charger Samsung has decided to include with the S3 NA is complete and utter crap. I believe it is .15amp draw. You need to immediately throw it in the trash and buy a new one. It is not a problem with your phone.

My Samsung Charger that came with the phone is 1Amp...charges the device fine. I don't think the 2Amps will make a difference if the charging chip doesn't support it (not saying it doesn't but the SGSII would only charge at 650maH no matter what charger you put it on)
Mine's charging insanely fast with the stock cable. Not sure if it's a good thing because battery life isn't all that amazing on my phone so far.

doesn't that mean each USB port is 0.5 amps?
Anyways if I'm not wrong the amps has to do with what it can supply. Whether the device tries to draw that much power is up to the device.
The stock charger is 5V 1amp.
Even if you use a 2 amp charger it will likely only draw one amp.
Even if it does draw 2 amps that would mean you are increasing the heat associated with more current. Heat is the worst thing for battery life. Its always better to do slow charge unless you're in a hurry. Your battery will last a lot longer that way. Having said that, I think 1 amp is a good compromise for speed and heat.
p.s. computers output 0.5amps per USB slot by default specifications.

The charger looks identical to the one provided with the S4 and Note II, it's 2A after all.
However it isn't! Galaxy Charge Current Lite (in the play store) shows 1200mA when plugged into this charger.
However the charger included with the Note 3 will show 1800mA.
The difference is the output voltage. The Note 3 charger is 5.3V whereas all the others are 5.0. This slightly higher voltage can allow the phone to charge at the higher current even if your cable has a bit of voltage drop. I have not tried with other cables however.
The (Note 3) does seem a bit more sensitive to charger type and will drop down to a lower charge current faster, however.
My 10Ah Anker bank will charge at 1200mA, for example. The 2A car charger I have also charges at 1200mA.

I've noticed that the note 3 charges a whole lot slower than the note 2. It actually seems that this phone charges 1/3 slower than the note 2 which makes perfectly good sense to me considering it does charge at 1200 vs 1800. One time when i plugged my phone in while using galaxy charge current pro ( auto refresh checked ) it clearly read that it was charging at 1800. My phone charged really fast. It only happened once though. I've used other chargers with the oem cord and other chargers with other types of usb cords. It doesn't matter what combination I use I still get 1200. Maybe it's something limited at the kernel level....
I saw this strange behavior connected the phone to my pc with the original cable in usb3, 2 times it charged with 1800 but most times is going to 1200 and I haven't understand why this is happening yet.

OK not sure if galaxy charging current lite is reading correctly. I plugged in an old iphone "block" style charger, connected a non USB 3.0 cable and it said 1800mA! It dropped to 1200 when I refreshed it.
Plugged in the included USB 3.0 cable and 5.3V charger and it did the same. So not so sure about this.
However with 5.3V the phone should be less sensitive to cable length. Look out, 10 foot cable here I come! :laugh:
Ehh not true because on my note 2 it said 1800 with the note 2 charger. It depends how much stuff is plugged into that socket. And to others who say their note 3 charges slower, mine charges faster. If it is plugged in by itself and not have several electronic devices plugged into the wall.

Nah because downstairs in my house my note would charge at 1400 with several equipment attached. And upstairs in my room with nothing on a wall socket it was doing 1800.

I have innergie 3A shared USB charger and it charges Note 2 and Note 3 pretty quickly (usually within 2 hours), but I found the phone gets rather warm if I use this charger, so I'd stay same and use a bit lower current.
Kensington Absolute Power can charge Note 3 quickly with 2A out.
Indeed, shorter (with lower voltage drop) and thicker (allows more current) USB cable also helps.

The chargers are SMPS (switching mode power supply) and can provide +5.3V @ 2.0A continuously with an input source between 85V and 250V 50-60Hz. I would not be surprised if you could put 10 car batteries in series for 125VDC and that would work the charger as well. Many SMPS can use DC too. NEVER connect that directly to the phone, you will have explosive charging indeed.
If your line voltage from the wall is dropping below 85V you have a serious issue that should be checked by an electrician! (or have way too many phones charging)
Well it doesn't affect my daily life or other electronics. So I'm good and don't need hire an electrician lol.

Billiy is correct. As an electrical engineer, the only way you would have voltage loss is if your house wiring was incorrectly installed as series. In that case, you have bigger issues than how fast the phone charges. Wired parallel there will be no voltage drop. So there definitely was an outside factor in your results with upstairs vs downstairs.
I used same charger and cable. Look all I'm saying the only benefit of USB 3.0 is if you're using to charge through a laptop or PC through a usb 3.0 port. Because through the charger it's only delivering 2 amps regardless of usb 2 or 3.

This is true, no matter if I use my s2 cable or my n3 cable charge is same. Only reason for usb3 is faster file transfers.
Guys I noticed something, we all see sometimes phone charges at 1200 and sometimes at 1800, I saw finally that if the screen is off it goes to 1800 and with screen on it lowers to 1200.

Well for me it didn't matter it charged at 1800 with screen on and sometimes dropped to 1600. But the fastest is with phone turned off.

Not my video just watched it and am sharing it. It slightly charges faster.

I saw your video and afterwards I'm still not convinced. Neither is my co-worker who also had a note 2 and now has a note 3. I was using my friends charger from the s4 ( the 2 amp samsung one that looks identical to the note 2 ) and it was charging my note 2 slower than normal. So I pulled out the galaxy charge current and his charger was only charging at half the rate and would fluctuate big time if I moved the cable. So Without you running that app or proving somehow that this phone is charging at a certain current vs another one at a certain rate then this test could be counted invalid...
My phone only shows 1800 if i first unlock it.
Else, it shows 1200 sometimes 1250. Does that mean it cant charge at 1800 when the screen is on?
CHarging is good but the battery is not good
the note 2 have 3100 mAH and NOte 3 had 3200.. i wish samsung will upgrade the battery more than 3200 mAH..
I'm rocking the zero lemon battery and since I've bought plenty of chargers and none seem to fix my slow charging problems is there any wireless chargers? Will me using the zero lemon battery not allow me to use a wireless? Also if all this is fine, does anyone have any recommendations??

Even though you can try to use that battery with wireless charging it won't fix your slow charging rate. Wireless charging goes max to 0.6 A (600 ma) when it comes to charging. So it's 1/3 the speed of your regular wall socket charger.

When I say slow charging I mean it comes up on my screen saying charge it with the cards given. It charges about 30% in about 9-10 hours.

Something is wrong with your charger or cable then. My ZL charged from ~78%-100% in about an hour last night. The plug adapter that came with the phone and a USB cable I've used for a while, from a Nook I think. Wireless will be VERY slow. It's fine for topping off, but if you drain it down you will want to use a wired charger. You can use a wireless charger with the ZL, there's some info in one of the threads talking about what you need to order. You can't use the contacts on the back of the phone for it, you need to use one of the low profile USB plug type.
If you want fast charging you need to use the adapter that came with your phone, or another known good adapter, and a good quality USB cable. It doesn't have to be USB3, a USB2 cable will work fine, but it needs to be good quality. Monoprice is a good place for inexpensive, but good quality cables.
If you are connecting to a computer USB port, you will charge slow unless it's a USB3 with a USB3 cable.

I've bought a couple chargers on eBay and they said it was OEM, but neither have worked. One was a Motorola and the other was one specifically made for the Note 3, or so it said.

Didn't you get one in the box your phone came in? Try that one. Like batteries, chargers are often fake and don't meet the specs they list.

Try a usb 2.0 cable to charge it.
The little extra part for the 3.0 seems to have gone bad in my phone after only 4 months.
If I charge it with the cable that came with it, I have the results you are saying.
If I charge it with a 3 year old usb 2.0 style charger, it charges fine.
Good luck!
Get a usb voltage/current tester. They are like $10. You can test all your chargers and cords and find the under performers.
My phone with zerolemon charges fast with the original samsung charger, and my Asus t100 charger. Fast being relative, from 20% to full it can take 4 hours or so. I've never timed it 100%

Does your battery seem to die quicker right after you unplug it?

Yes, it drops to 97% straight away. This is because it drains in the background a little as the charger doesn't trickle charge. See this for an explanation http://www.androidpolice.com/2010/1...bump-charging-and-inconsistent-battery-drain/
