I would like a longer cable that will also allow charging from computer USB, car charger USB port, etc...
Basically I don't want to be limited to having to have that brick of a Samsung wall charger with me, and of course the longer cable.
Can anyone recommend one? I've looked on Amazon but all the descriptions just aren't clear enough...
Unfortunately I have been reading that the "bulky" charger is the only one that will charge the tab properly. My suggestion would be to buy a USB extension cable to solve ur short cable issue.

Really? I swear I read of a cable that would work on computer USB.... darn, my cable is short circuiting at the 30 pin so I need a new one regardless. I have an extention cable already.

I leave my tab plugged in overnight to my pc using the supplied samsung usb data cable. It charges at a slower rate but is typically charging about 70% over a 9 hour period.
I also have an USB3.0 2.0m extension cable (tried an ASUS transformer for a week), which allows charging and data transfer ok

That will allow the Tab to charge from any 2A charger (most common would be iPad chargers).
The tab will go into USB charging mode (e.g. charging disabled) with iPad chargers unless you use the cable above or modify the charger.
I haven't had time to investigate, but it MIGHT be possible to allow charging from unmodified iPad chargers with a kernel modifications. Not sure - it depends on whether we have separate ADCs for USB D+ and D- or not.
this will work, you could also buy the cable without the charger.

Dude not to be rude but the Guy is looking for a cable that will charge his tab from his computer. That is the stock charger and cable that came with the tab. That one doesn't accomplish the task

Can't charge from PC, not enough current available. Best you can do is adapters like th DX one to allow iPad chargers which are often more compact.

Tab, not Tab 10.1 - The original 7" Tab will charge from a PC, the 10.1 will not.
The cable will work with the Tab 10.1 just like the 10.1's stock sync cable - which means it will transfer data but not charge when connected to a PC.
Guys, I keep reading in this thread that the tab 10.1 can't be charged via a PC, well I'm here to tell you it can and does. Every night I leave mine connected to my PC, and in the morning it's charged! Admittedly it's a slower charge rate (seems to be around 6 or 7% per hour), but it charges never the less. I use the samsung supplied cable and nothing else.
Of course, it won't charge if the tab is in use via a PC USB port...
My device charges very slowly if the display is off. If the display is on it does not charge at all.
I've installed the Samsung drivers from the website. Is anyone else able to charge their device via USB? I need to know if I should exchange mine.

I was able to charge my sgs2 yesterday at work through the usb port. It might be the phone, or maybe the usb port you are trying to use doesn't have enough juice to charge the phone? have you tried another usb port on the computer?
usb will always charge really slow compared to an wall outlet
Yes I have tried multiple ports, computers, and cables. Oh well, I guess I'll live with it.

USB supplies max 500mA. Is probably half what the wall charger is giving you. Nexus S is only 750. My guess gsII is 1000 (1A). iPad charger is 2A.
Edit: no a higher power one than the stock charger won't charge the phone faster in a noticeable way. Charging circuits in remotely modern phones limit current to that safe max. If they don't you're probably risking damaging your phone.

I understand that the USB on the computer is weaker. I was surprised to see that when the phone was connected to the computer, screen on, and streaming music that my battery was actually reducing slowly. I would expect the opposite and this behavior seems abnormal.
Sent from my SGH-T989 using XDA App
that's exactly the reason why in car i use the 2A charger (2000 mAh), and in house i use 1000 mAh wall charger
if i leave it at the computer USB charging, i've to keep it iddle for it to charge after like... 4+ hours
that's usually what i do at the work place, so i keep the battery topped up, for when i need to jump back in the road
as long as you have WiFi on, or 3G/4G on, or if the CPU is in high activity, you'll never see the charge ever reaching the battery.
i always keep a spare wall charger at the office as well for times when i need a quick charge
Thanks for the input everyone! I'm glad it's not defective cause I love this phone!

My issue is a little different but decided against another thread. My phone will not charge with any other cable. Has to be pluged in to oem cable. I left it all night on my old phones charger and woke up with it almost dead. Plugged into oem it just charges super slow. Should i take it back?
Sent from my SGH-T989 using Tapatalk
Does the other micro USB cable work with other devices? If not, might be a defective cable.
On a side note, who prefers to charge via 500mah vs 1A? I have been charging my phone since day one using my printer, as well as my old Iphone. My battery performance is great! +24 hours on a single charge with moderate browsing 50/50 wifi and 4g. I typically enable the "power save" feature with minimal brightness and 15 sec screen timeout.

[Q] Charging problem
I have an issue that has popped up today. When charging through PC, the phone (not battery) is getting pretty hot and losing charge. I'm not sure what could be causing it. I stopped all extra processes and turned off the screen. This is not occurring when the phone is off.
Id like to hope im the only one whos experienced this. But whats going on with the charging? I love the dam phone but while charging it sometimes drops in percentage. Its happened in alot of situations. Stock unrooted, stock rooted, Frosty jb, and Xquizit. I try to underclock to see if that makes a difference but it gets worse. Can someone, anyone please help me out. It was even left on the charger last night and I awoke to 15%
Sounds like either a bad charger or a bad connection between phone and battery.

Thank you. At least its possible it may be the charger and or battery and not the phone. Much appreciated.
I don't know what rom you on now, just keep as stock for now then keep checking 1 or 2 day still have problem, bring back to TMO for warranty.
Are you using the usb cable and the wall charger that come with the phone? I noticed that when I am using my other usb cable I brought from the internet to charge the phone with my PC, which only supports max 500mA current per USB port, the phone doesn't seem to be charging at all. Just like the op said, the battery percentage went down even though the phone is saying it is charging. Then I switched to the usb cable that come with the phone, and plug in to the same usb port on my pc. What you know, it is charging correctly now, the percentage went up. And it charge much faster when using the 2A wall charger that come with the phone.
I think the problem with charger

If you are near a local T-Mobile store or distributor, why not pop in with your kit (phone, charger and cable) and do a little process of elimination to see if your problem is your phone and/or cable and/or your charger?
Ive been experiencing the same, but when using other chargers and usb cables. Weird. But it never happens with the charger the phone came with.

I just started having the same problem. I use to be able to use my phone while it charges and it would charge fairly quick as long as I wasn't heavly using it. Now even when I'm not doing anything on it, its charging ridiculously slow.
I thought it had something to do with my recent flashing of 4.3 but I flashed a MC2 restore and it didn't seem to matter.
Get the Galaxy Charging Current app. It will let you know the charging current. It should be *Now: 1698*. Mine would read 466 and I would reinsert cable(until I got a new charger/cable) until it read 1698. It appears there is a problem with OEM cable.

Been working great for ~3 months on my Sprint Note II. It said that when I downloaded the app too. Try the free version, I like it and bought the app for the dark background feature.
I would try another USB cable first. I was having the same issue. I tried a different cable I have around, and was charging like I was expecting. So, I order two premium USB cables from monoprice.
From the reading on XDA around here, it looks like the USB cable that came with phone get shorts in them fair easy; ie they're not very durable. For me, no biggie since I like to keep cables in various places--car, house, backpack, go to bag, etc.
It changing the cable didn't work, try a different charger. If that doesn't work, try the battery. If none of those work, then it's probably your USB port.
Although, the USB cable is most likely the issue.
If you've had the phone for awhile, try cleaning out the microUSB port on it. I used a toothpick and picked out a surprising amount of lint that had accumulated in there. It may help establish a better connection between the cable and the port.
Definitely seems to be an issue with the usb cable, I had the same issue, switched cable, and all is fine.

I love @ktoonsez kernel I also LOVE his fast charging option. Was using schools computer to charge and was charging at 900 mA love it.
Got tired of going through the app to toggle this. So i made a widget that can be placed on the home screen or the lock screen. Im sorry, the image is hideous. xD wasnt too sure of what to use as an image so bear with me xD
Just install the APK then either on your home screen or your lock screen add a widget and select Fast Charge Toggle. Done. Will prolly work on other kernels with fast charging option but only tested on @ktoonsez kernel
From almost totally dead, it takes me about two hours for a full charge with normal charging.
I've never bothered with tweaking charging settings. How much faster would fast charging accomplish the same thing?
Like the idea, but what does fast charging do ultimately to you're overall battery life and health long-term?

The fast charging kernel tweaks are only for USB devices. Like from a computer, stereo unit, cigarette lighter. Not from the wall outlet.

It has no side effect on the battery. The stock charger has I think like 2a charging power, most computers have only 500mA. Fast charging simply tricks the kernel into thinking it's plugged into a wall outlet and charges at the full power available. The only side affect is that it could ruin the USB port. However after two years of using it I have never seen any issues myself nor have I read any.

According to what I personally saw in the source code and what @ktoonsez said, the fast charging gets ignored when it's an ac charger. Just going off of source code and what the code actually does. Might just be a placebo effect on your end all in all tho fast charging sure is the best thing since sliced bread xD

I have a car charger that has a spare USB plug on it. If I use the actual car charger it charges as normal, but when I plug in the white USB cord that came with the phone into the same car charger it definitely charges almost twice as fast. Living proof. I was on a road trip using GPS and LTE while streaming music. While on the car charger it would almost not charge at all, just supplement enough to not drop in percentage. Then, when I switch to the other USB it charges up no problem.. Really works.
Elesbb,
First off, Thank you for making this and sharing it to the community. I have been looking for something just like this. Comes in very handy.
I don't know if you update this anymore, but I was wondering if you could make a choice for different icons for the widget. If not, no big deal, the icon is just a little too cartoon-y for me.
Thank you!

I just googled "maximum usb milliamp output from a standard computer usb port" and to my
surprise I must have found at least 25 links which I read that deals with this subject.
And all of them specifically point out that a normal laptop or desktop computer's usb port puts
out a maximum of 500 milliamps unless someone has some special usb pci/pcie card installed
inside their home computers, I never seen any that do but it is possible that such a card exists.
So this mod would really not do anything at all, it would not charge faster and it could not hurt
the usb ports of any computer since it cannot change the max. milliamp output of the usb port.
Now if we had some kind of special program which we install in our computers to allow the usb
ports to put out 2amps (2000 milliamps) then it would charge just as fast as our wall AC chargers do.
But modifying anything inside our phones cannot change the fact that it's the computer and it's usb
ports which determines what the maximum amount of milliamps that it can output.
Look at it this way, if you have a 5 gallon gas can you cannot pour 10 gallons of gasoline out of it.

The maker of this (ktoonsez) stated this in his thread. However, a lot of computers (newer ones) do have higher power outputs to power things like external hard drives, cooling fans... etc. For instance, mine, when paired with the fast charging mod, outputs 700ma but without, stays at 500ma. So while you are correct, there are a lot of computers (especially newer) that do have huger output ratings. This is clearly seen when my external hard drive won't work on my grandfather's dinosaur computer (even his new printer has issues). But plugged into my laptop, it's has no problem.
Also, I believe USB 3.0 has a 1amp output.

You know what, you are just about right, I just did some more googling and found
that the usb 3.0 ports on newer computers do have a greater output than 500milliamps.
They have a maximum of 900milliamps, still no where near the 2000milliamp which
the home charger puts out, but it's close to double of the standard usb 2.0 ports.
I read that many newer computers including mine has a dedicated 3.0 port which stays awake
even if we turn the computer off & it continues charging whatever is plugged into the 3.0 port.
So 900milliamps is a lot better than 500milliamps when comparing usb 2.0 to 3.0 however
current is current, the phone itself cannot distinguish between a 500milliamp or 900milliamp
charging rate, if it gets 900ma it will charge a lot faster than if it only gets 500 milliamps.
All cell phones have a safety feature built into their circuitry which prevents us from charging
the phone at a higher rate than what Samsung specifies by plugging it into a charger which puts
out more than 2amps, if the phone did not have that circuitry it would dramatically shorten the life
of the battery.
That's why Samsung ships 2amp home chargers with their phones and not a 2.5 or a 3amp one.
If this mod which is being discussed here defeats the safety feature in the phone's circuitry which
prevents it from being charged too fast then I would highly advise against installing or using it.
The only time a higher rated battery charger should be used is if we have an extended battery
which was rated at let's say 4200milliamps in which case a 3-4 amp charger would be best.

It doesn't defeat the security of built in kernel protection. Androids own API has a way to detect if the plug is wall charger or USB. The mod simply tells android OS that the USB charger is an AC charger and to not limit charging to USB levels. That's why USB doesn't work when the mod is enabled. It's no way harmful to the device. Been using it since I've gotten my phone and even back on my s3.
