Out of the blue I noticed my S3 was charging very slowly, it even was losing a charge while it was plugged in while I was using it. I figure it had something to do with my custom ROM so I reflash, still same outcome. The battery was still holding a good charge, so I figured it was something else. I then went out and bought a new charger, which came with a micro usb cord to see if that helped. Plugged in the new charger while using my old micro usb cord, still same outcome. Then used the new micro usb cord and old charger, charging went back to normal, problem solved! I would of never thought that the cord would malfunction from day to day use after such a short lifespan. Moral of the story, check your cords if you experience the same problem, it could save you some time and money!
I bought some cheap ones off Amazon. They won't charge the s3 but will my touchpad. But my s3 charger won't charge my touchpad. Stuff is weird at times.
Glad it was an easy fix.

I believe it, using my old galaxy nexus cord for my s3 charges extremely slow (like 200 mAh) for some reason. I switched to a different cord and now it's all good, I have no clue why but that's how it is.

I really think that those cheap cables don't charge nearly as fast. Especially the Stock Sammy ones. I use the thicker LG cables and they seem to charge so much fast and transfer files faster..
I just went through the same thing. The phone was charging for twelve hours and only gained 50 percent. Took forever to figure out it was the cord.

That's what my phone was doing, I'd unplug then plug it back in and would go from USB to AC, but it still charged slow. That cable, no matter what it said, would still charge slow as balls.

I had heard of "Buy Cheap, Buy Twice", but now we've got "Buy Cheap, Charge Twice"
A lot of times it's the DC power brick that makes the difference. Not all of them have the same power output. Rarely, if ever, is it the actual cord itself. USB cables use pretty thin gauge wire already and the only way you're going to get a difference from one cable to another would be if it was REALLY cheap and using an ultra-thin wire or if it was a REALLY long cable (increases in cable length equate to increased resistance to electrical transmission...)
All USB cables are 5 volts. However, there can be significant differences in the milliamp output for each DC adapter. Aside from being a computer geek and gamer who builds custom PC's, I happen to be a hotel General Manager. I just checked our catch-all box of phone chargers and found that while every charger has an output of 5v, the amperage put out varied from 350 mA to 1000 mA from one charger to the next.
This variance in output is why some chargers take so long as compared to others. I don't know what the actual Samsung charger output is, since my charger is at home, but my guess is it's between 800 and 1000 mA.
I use the stock BB charger to charge both my 9900 and GS3, the BB charges pretty normal but lately I've been having a problem with the charging time on my S3, I have to charge it everyday now, my usage isn't that heavy, it lasts me a day and a half normally. Going to start using the stock charger to see if there is a difference.
I'm using the Samsung stock charger after not having used it for a month and noticing that my battery levels have deteriorated after using my BB stock charger. The battery seems to be discharging while on the charger! I'm in for a world of pain, going to monitor it for a while. I could be stressing over nothing.

Does anyone know of a good car charger? You know, the kind that plugs into your cigarette lighter socket.
I had one at one time but it died after only a week of usage.
I got this one and it works fine with a spare microusb cable. Best part is that I can now have two phones charging at once.
Thanks!
At only $8, that's a steal of a deal! Just bought it with free two-day shipping.

In my opinion... I have wasted alot of $ on trying to get away cheap on a car charger. By far the best one is the official verizon one. It charges to 100% from 0 in less than 2hrs and charges while I am navigating, wifi tethering and using bt at the same time. Well worth the extra cash.

I got a similar one, but it has one port meant for an ipad/tablet, which outputs 2A - that is helpful for when I am running car navigation and wifi hotspot at the same time. I also had to get a charging-only usb cable because regular cables would trigger usb storage mode on the phone.

To bad the Charge won't draw more than ~0.8A... Also, it is the charger causing the phone to go to mass storage mode, not the cable. A microUSB cable is a microUSB cable, and if the cable says "charging only" they have the data pins shorted out (I believe that's what is done) and it really isn't fixing the root cause of the issue.

The only way you could speed up charging would be to modify it via the kernel, or try to force load a module that does the same thing. Odds are the fastcharger script just gets the system to recognize USB charging as a wall charger. Either way, I wouldn't recommend using anything that says it'll make your phone charge faster unless there was SIGNIFICANT data to support the claim as well as evidence that it doesn't harm the hardware.
Charging the battery too fast is very dangerous too. I tried "supercharging" one of my batteries and it almost caught fire.

It could be the cable, but the odds are against that. The way to tell if it was the cable would be to try it in another AC charger to see what it does.

Samsung smartphones and Tablets charge in std mode (Charging USB) unless the two data wires are "shorted". (I have seen it done directly in a high speed charge only cable or in the Samsung chargers. Some say they use a resistor.) When the data pins are "shorted", Samsung switches to high speed charging. (Charging AC). I have been harassing a factory overseas for a dual car charger (2100mA) with one std. Port (iPad) and one Samsung port. It should be available soon.

I haven't tried another car charger personally, but can vouch for the Verizon one. Always works for me and I just leave it plugged in the lighter outlet in my center console so whenever I need it, it's easy and quick to plug in the phone. Also has the scrunchy style cord to keep things neat. But at the same time, it makes it more difficult to use the phone while it's plugged in as it keeps wanting to pull back lol
Usually, when I charge my phone, it charges pretty quickly, despite the output of amperes; however, when I charge my phone using an outlet nearest to my bed, the charging takes considerably longer, even with a 1 ampere output. (I usually use .7). Also, when I use the phone during charging, it even loses battery... like the percentage goes down. Do some outlets in households have a lower output of energy? Anyone have any ideas?
What rom are you on? Some roms have a fast charge mode. Open Terminal and type "ffc" without the quotes.

No. Most household circuits have a circuit breaker with 15 amps of capacity. More than enough. However, the outlet itself or the wiring on the back of the outlet might have issues. Does your charger fit snugly in the receptacle, or is it loose? If it's loose, you are probably getting an intermittent charge. A good outlet should require a little bit of pressure to plug something into it. If your charger just slides in easily, that could be causing your problem.
Good luck.
have you tried different chargers in the outlet. some chargers appear to the phone to be a usb port (and enable a slower charging mode).

Just got an HTC One X (+). (Assume charging issues will be same as One X.) I used it only for a couple hours after getting it yesterday then it charged overnight via USB. Ran it down to 55% today, then plugged it into USB. An hour later it is like 65%. Holy crap, that's slow. Problem is, I like to charge my phone on my desk next to my computer while I work so I see any calls/info that comes in and can transfer files. Looks like I'll have to get an extra long mini-USB cable to plug the charger into the outlet underneath the desk when I need a quicker charge during the day. But then if I want to transfer files I need to change cables. What a pain.
It may be some background tasks running as for about 20 minutes I was playing with the phone and using a website with heavy flash and could feel the phone get hot. Actually saw the battery percentage tick down 1% while plugged into USB! This CPU can eat battery like no tomorrow when you push it! However I've seen some other discussions about the USB charge being slow, but THIS slow - like probably estimate 6-8 hours slow on USB?
It's plugged into a newer Samsung Series 6 high-end notebook. I suppose even if the charge goes way down, it's going to take the better part of a day, if not the entire day to do that, so by then, I don't mind plugging it into USB overnight. Pretty surprising though. My iPhone 4 charged like 10 times faster via USB.

USB charging is limited to 500ma max, depending on the pc. Your computer might be supplying less. Your charger puts out 1a. It will be at least twice as fast. I charge my one x with my Asus tf300 charger which is 1.7a and it is even faster.

I suppose since the X+ has a higher capacity battery it takes even longer to charge than the X/XL.

Only 300 mah larger so it shouldnt take more than 15-20 mins longer to charge.

If you're using more juice than you're taking in, it's going to be slow, or even negative, when plugged into anything. Pretty simple equation.

Well my iPhone 4 was 1420 mah, and this One X+ is 2100 mah. So charging it USB, theoretically should take 1.5 times as long. But that is with CPU usage during charging being equal. Seems because of the "truer" multitasking, the Android platform is a bit more prone to background apps or services periodically eating up CPU which could further the charging time. I'm wondering if either using Llama (or Tasker) and/or JuiceDefender Pro (have them all, haven't got to trying them) I can set up some sort of "Charging Profile" that will essentially shutdown all but the most essential functions and apps/services. When plugged into USB on my PC, WiFi doesn't need to be turned on (unless I want to do something with the phone require a net connection while it is plugged in). Probably other tasks/setttings that can be turned off too. I'll probably just run a second cable from the AC charger to my desktop so I can easily choose. Suppose I could always use Airdroid to transfer files while plugged into A/C charger.

I have had my Verizon Galaxy S4 since February of this year. I've been using the stock Samsung AC charger that came with it. It's always charged the phone pretty fast if I wasn't using the phone. It would charge about 15% in 20 minutes. Now it's only charging about 3 or 4% in 20 or 30 minutes. Now I didn't do anything different to my phone. I've been on this same ROM for over a month and this is just now a problem in the last week. My wife has the exact phone and charger that I have and when I use her charger it charges just as rapidly as mine used to, so I know it's not the usb port on my phone itself. I haven't dropped or damaged my charger at all in any way either.
Does anyone have any ideas about why this is happening?
If it charges fast on you wife's charger you've pretty much answered your own question.
Try using her cable with your charger, if it still charges slow then get a new charger.

I had the same problem too ! Did a full battery reset and everything is going good now !
You have to charge it for 12 hours and drain your battery until your phone don't boot. Charge it and here you are !
Yeah these devices act funky every blue moon. My wifes didn't even recognize ANY oem charger for a week. Only detected others as USB devices causing slow charge rate. Removing dust, component cleaner, fresh install, all did no good. Eventually it just resolved the issue itself. All chargers work normally again.
change the usb cables
I also had the same problem before. I'd been using the original charger and usb cable and noticed that charging takes a lot of time than normal.
I found that it's on the usb cable. I accidentally found it when I used gsam battery monitor. It displays the current being received by your phone when charging. Using the original usb cable, it only gets around 600mah. I tried another usb cable (from a previous Samsung device) and now my phone gets 1,900mah (closed to the charger output of 2,000 mah).
Every since I changed the usb cable, my charging is fast now. Hope this helps.

How do you make full battery reset?
The charging rate is based on the output rating of the charger, which is determined by the resistance value between the Data+ and Data- USB pins. If you use a cheap cable with high(er) internal cabling resistance, that will throw off the detected charger output capacity rating, and knock you down to a lower charging current and longer charging time.
Also, one time, even with the original charger and original cable, I couldn't charge at anything more than the default USB 500mA. I ended up having to power off the phone, and power it on again, which fixed the charging current and speed problem.
Install this app & check if it is getting charged at max current; anything less than 1200 mA when screen on & 1900 mA when screen off, you need to change your cable or charger

Downloaded a galaxy battery current charging app and it shows negative amperage when plugged into 2a charger. Also with the screen off it only shows one green dot instead of the trail leading to the battery.
Sounds like your 2 amp cable was defective. I've plugged mine into a 2 amp and it just takes a lot longer to charge
I thought so too, so I used the brand new cable that came with the n5, same result.
If the other cable was defective it could of damaged your usb port possibly. I use a 2 amp in my car sometimes then my 5 amp at home no ill effects
I use my note 3 charger every night because ive always heard a slower charge is better for battery longevity. I have had absolutely no problems and wake up with a full charge after a average 5 hour sleep every morning. I only use my note 5 charger for quick fill ups during the day.
