[Q] Charger with different USB cable?

Seeing as all of my old chargers are for my SGS2 and put out a measly 0.7A compared to the 2A of the note 2 charger, I was wondering if I can use a different USB cable with the note 2 charger and still get the full 2A from it?
The reason I ask is the original USB cable that comes with it doesn't seem to be well thought out and has difficulty staying in if you move the phone about while charging.

Got the same issue. Tried galaxy Nexus cable. And it barely charged several percent.

Most cables should work. But it requires a good quality and moderately thick cable to provide close to 2A without a massive voltage drop.
You could try to shave a little of the excess plastic from the original SGN2 cable, so as to make the connector longer. My phone does not have a problem holding to the USB connector as is, but it seems quite a few other users have some trouble.
If you really need a new cable, try to avoid the cheapest ones. Also don't get one longer than what's needed.

I bought a 3m long cable. Works just as the regular. This cable is about as thick as the original. I would avoid the very thin cables when using the 2Amp charger.
Just a warning... If a cable does not fit, do not make it fit. Mine did not at first. Adjust the "hooks" on the contact by pushing them in slightly. There will be less force needed when connecting and it will still sit more tightly than the original.

Just buy a USB extension cable.

I'm using the original charger with the cable from my Kindle paper white and it seems to charge just fine. What's the advantage of using thicker cables?

Would using an extension cable degrade the current?

I noticed that the Note 2 is a hungry beast. Have it for two days and tried to charge it on my Note 1 craddle with the Note 1 charger. Charged for 6 or so hours but was only at 57% when I took it of. You definitely have to use the 2A charger and mind the cables!

My Note 2 came from Handtec and was in French packaging, and the Samsung 2A charger was a 2 pin version but Handtec had supplied another charger with the UK 3 pins. This works fine but is only 1A and I've been using a range of other micro USB chargers and they all seem to be ok.

That's what I was wondering. I will buy and use one, then give feedback.

Okay, just tried a cheap extended usb cable and initially it showed charging but within a minute it wasn't charging anymore. Enough of cheap cable, now I'm gonna search about Belkin usb extension cable.

I don't think it's fair to say that, at least regarding the chargeing cable. Samsung uses a regular microUSB connector, just like all phones sold in the EU should. It's Apple that insists on proprietary connectors.
The Note II has a large capacity battery (good thing, right?) and Samsung decided to provide it with a power converter capable of chargeing the phone in a relatively short time. It requires a moderately good quality cable to allow a strong current to reach the phone within USB limits, but that's just physics. Not Samsung's fault.
(I do, however, blame sellers of very cheap cables. Buyers are the ones who suffer because the manufacturer decided to shave a cent or two from their costs.)
What I would recommend those that need a longer cable is to get an electrical extension instead.

Besides being physically stronger it can also have slightly thicker treads, allowing a bigger current, with less voltage drop until it reaches the phone. Orginal cable is 23AWG (power) and 30AWG (date). The thinner they get the more voltage drop, the longer they get the more voltage drop. The voltage drop is also affected by the material of the cables... The thickness of the cable may just be stronger shielding or better isolation, so look at the AWG markings and avoid too long cables.
My 3 meter, 24AWG (power) and 28AWG (data), error... sigh... AWG size is opposite towards milimeter... The lower AWG the thicker thread in the cable. The lowest AWG threads on the cable is for charging.

ElectroDroid can calculate voltage drops. I really need to little shorter cable

I've got saerm problem, the reason is that the micro usb tip ( the one you insert on the Note 2) is short. It can be easily solved by buying a different cable, or like what I did, I just filed the surrounding plastic to make the metal bit longer. It now latches perfectly with a click !!! Good luck

I have used both sgs2 and note 2 cables wt note2 charger both cales r propriety samsung i put my note 2 battery to 5% abd charged wt the note 2 charger
Both cables took 5 hrs to fully charge note 2
So i think if u use propriety samsung galaxy series cable it dosent matter
The i charged the phone wi sgs2 original charger
It took about 8 hrs to reach frm5% to 100%
So i think the output of the charger matters not the cable
I cant say the same about non propriety usb cables as i havent used those
I have a micromax a 7o usb cable which runs androud
I will use it wth the note 2 charger and post result

I did not say there would be extreme differences, but if you want a good quality cable... It does not say what AWG the SGS2 cable has (I find no markings), but the cable is a factor, but a small one, than can be noticeable especially if you have some length on the cable. If you use 1Amp on a 1.8 m 28AWG copper cable there is almost 16% voltage drop. If you double the current you also double the voltage drop. That does not mean that the charging time will be changed much in some cases since there are other factors that affect it too (internal electronics that handles the charging, battery health, the real charge Voltage/Current at the battery leads....).

I just got a high quality cable from Manhattan Products and their website says:
http://manhattan-products.com/en-US/products/9204-hi-speed-usb-device-cable
28 AWG conductors
Shielded
Withstanding voltage: 300 V DC 10 ms
Insulation resistance: 5 MOhms
Contact resistance: 10 OhmsThermal plastic casing.
What's the AWG of the original cable? Is my cable's awg for the data or current?
Sent from my GT-N7100 using Tapatalk 2

Orginal is 23AWG power and 30AWG data. You can read it the cable actually. You even see that it has dual commons.
If it has dual sizes the bigger size is power (bigger is strangely enough a lower AWG). If it only mentioned one size then it is used both for data and power.

Is it safe to use this cable for charging my phone?

My phone is nokia X1-01 basic phone
It comes with AC-3 charger
I live in a home and office where power plugs are very rare to find but lot of usb ports. Those days i use smart phones they are easily chargeable as they had micro usb. Can i buy the below cable to charge my phone? I know it is compatible with my phone but my worries are will it reduce the life time of phone or battery? I don't worry when i charge my older phones because they had micro usb that as every one know always same voltage and amp.
http://www.ebay.com/itm/USB-to-2mm-...195162?pt=PDA_Accessories&hash=item4155abc6da

I have three phones with microusb
I have three phones with microsub, and i charge all with diferents microsub cable, sometimes with the microsube of my digital camera. My phones are lg,sony,and one chinnesse phone. I don't see problems with the microusb and don't feel something strange in the life time of the battery.

Don't worry about battery life. Perhaps it will charge a little bit slower than with a real power adapter, but there's most likely no difference at all.

[Q] Slow Charge with Including USB3.0 Charger

So this is an update to a previous issue I had...
When I first got this phone, the included USB3.0 charger charged much faster than a standard microUSB charger. But then it stopped charging fast. It pretty much stopped charging at all really. Like maybe 1% battery added in like 20 minutes.
So I sent it into Samsung and they returned it saying they couldn't replace it because the wall adapter part was actually from a Note 2 which doesn't support the 3.0 wire (even though it was absolutely the one that came in the box). Once I got it back, I found a brand new set of the same wire and adapter (it was covered with the packing plastic wrap and all that stuff which is what makes me think it was actually a replacement). I plugged in my phone and it charged quick again for about a day. Then it went back to charging slow again.
I still need to get down to T-Mobile to see if they'll exchange the wall adapter which supposedly doesn't work with the USB3.0 cable even though both times it worked at first. It's their mistake but I have a hard time believing they'll own up to it... The model on the adapter by the way is EP-TA10JWE with an output of 5.3V 2.0A.
Assuming they don't exchange it... What do you guys think are my options here? I ordered a 3rd party USB3.0 cable from Amazon and that does the same super slow charging as this (and it didn't come with a different wall adapter anyway so it was kind of a stupid purchase on my part). I tried plugging the cable into a computer with USB3.0 and it didn't make a difference. Is there a different wall adapter that is known to work with the fast charging on this phone that I can buy? Is it AT ALL possible that the connector on my phone is the problem and I need a new phone? That would be terrible, but if it's something I need to do I will. It charges just fine and the same speed as any other phone when I use a microUSB cord and adapter like the one that came with my old S3.
Any thoughts?
Thanks

That's weird brother. I checked my charger and i have the same model number and mine charges extremely fast. Maybe it's a problem with the device it's self.

no not rooted (i was thinking about it and then this whole thing started)

I've noticed the same thing with mine ..and definently trickling on USB 2 .. I thought USB 3 was suppose to be all the hype about how it would do when u turn fast charge on in a rooted phone with custom kernel.. The charging is slower than my note 2 on USB 2..

its so weird that it DID charge faster for that first couple days (and again after I got the new one)... And I have 2 friends with Note 3's that say they charge faster than their previous phones (one of them had a Note 2).
I just don't know what to do...

The enhanced speed with USB 3.0 is for data transfer, not charging. Using a USB 2.0 or 3.0 will charge your phone at the same speed.

Well first of all, every review says it charges faster with the included 3.0 charger... So I don't see how you could be right about that... Not trying to argue, it's just that was one of the features that everyone talked about... And second of all, the 3.0 charger that came with it barely charges at all anyway anymore, so even if that was true, either the cable, adapter, or phone still has a problem... Phone charges fine, maybe 3 hours for 100% charge with a microUSB cable... About 1% in 10 minutes (that's as long as I can bring myself to bother testing the 3.0 charger for). And that's if the screens off. If the screen is on it actually just won't charge at all, it's like it drains quicker than it's charging with the screen on with that 3.0 cable... Again I say "cable" but it could be the cable or the adapter or the phone that's the problem... I'd love to find a way to figure out which it is...

For some reason the 3.0 charger charged lightening fast today ... Maybe the jedi ROM had to settle in for a few days maybe?

Slow charge

Hello xda members, i have been experiencing a problem on my tablet Samsung Galaxy Note 10.1 (2014 Edition) Android version 4.3 since the past month. It does not charge as usual and a red cross pops up on my battery icon indicating slow charge. I don't know if it's the adapter or usb cable which is causing this, but I tried a set of new charger and cable ( Sony brand ) and still I get the red cross.
What do you advise me to do?
Do i install an app from the store to check if my battery is causing this or do I need to try charging it with a new original adapter and usb cable?
Thank you and awaiting your reply.

The red cross only indicates that the tab is not recieving enough power and even if energy is coming in, it is not enough to charge while using. Understanding this, anything can be cause for the current not being enough:
The adapter could be damaged.
The adapter you are using is not the samsung one and thus is giving less Amperes(Out tab needs 2A and most adapters give 850A-1A).
The cable is damaged.
The cable you are using is not prepared to transport 2A.(This happens to me with the chromecast ones)
The microUSB port on the tablet is damaged. An indicator may be the tablet overheating like crazy when charging but this is not probably because when this happens the device, in most cases, takes energy or not.
I personally find that the cable, if you are using samsung's adapter, is most commonly the problem. Using a cheap cable or a damage cable causes this for most of the tabs I have known.
Hope this helps.

Thanks for replying mate, actually I'm using both original samsung adapter and cable which came in the box.. I will be heading to some shops looking for a Samsung cable and see whether it resolves the problem or not.. What is weird is that sometimes it has the red cross and sometimes it doesn't. Yesterday evening it was slow charging and this evening it was normal charging.

It happened to my brother, he changed cables and changed from light socket and he said he had no more problems; he also may have cleaned the usb that goes into the adapter; ol' "blowing nes carthige" style. I would recommend getting a Q-Tip with alcohol and cleaning every metal part you see in your cables, speacially the 4 metal bands inside the male and female usb port from the adapter and the cable(remember to let it dry before pluggin it again).
BTW, it must be a good cable but it is not necessary for it to be a samsung one. If you have a good phone around and can use that cable, it should be fine(I use a motorola defy one which had a 850mA adapter and it works marvelously; "meh" cellphone but the accesories are darn good), just dont use other adapters because of the Amperage difference.
Also, if you are using any kind of extensions, specially usb port extensions, don't. They are a sure culprit of the problem you are experiencing. I dont know why but these cheap electronics really affect the energy passing through; maybe its the cheap copper or bad solder.

Some questions on charging battery issue

Hey guys. Just wanna ask some question.
My note 10.1 2014 P601 is now running stock 5.1.1 un-rooted. Basically everything stock. I know that our Note need its own charger to work properly. But I lost the original charger long ago, and I've been using only the USB I bought separately to charge my tablet by connecting it to PC.
Now, my mother just bought a new phone (Galaxy A7) and when I try to charge my tablet with her charger, sometime it shows X mark (which means insufficient, exactly like when i connect to pc via USB cable) on the battery icon, but sometime it shows the lightning (which is fine) icon. The speed of the charge depends on that sign, if on lightning sign, from 0 to 100% takes about 4h. But if on the X mark sign, 4h will just get around 40%.
I don't really know what happened, but I have to unplug then re-plug again and again to get the lightning sign to come up. I then bought a new charger (from a legit well-known store and they said it's the best quality) and it does the same thing. I haven't got a chance to borrow anyone's original note charger yet as I found no one using this device. And now I start to think it's the problem with my Note more likely than anything. I haven't tried to reinstall the firmware either as I just updated the firmware like few months ago.
I've been using it for about a year btw. Sorry for my English. And looking forward to hear from you all.

The usb jack or its solder contacts may be damaged. Also, if no case is used and the backside of the Note squeezed when holding it in your hands, the cables for usb and display may work themselves slowly out of their pcb connectors. I don't know if the squeeze theory is right, but definitely there are many loose cables...
A charger must be Qualcomm Quickcharge or Apple iPad compatible, 5v 2A. I haven't used a Sammy Charger for a single time,tho they seem just too good to throw away.

Are you sure the Qualcomm Quickcharge would work on this P601? I checked the list before and I didn't see the Note 10.1. Not even the Note 3 which was released together. I afraid that being "not compatible" might fry the device.
If you're using one and not having any problem, can you post the link to the product that you're using and working well?

I forgot about the different SoCs. However, all models charge at 5v/2A and the signaling technique used for Quickcharge seems to be borrowed from that of the Apple iPad, the Exynos based models should be just the same. I plugged my Note into an Apple compatible charger, which was from a time when Android smartphones were charging at 0,9A and Android tablets had proprietory connectors, and it was charging at 2A.
