Have you tried another cord, I had an issue like this and a new cord fixed it. Also are you charging through a computer or wall socket or both?

USB to PC
I would try another cord and/or a different pc if possible.
Also check the battery stats to see if a certain app takes up a lot of battery (it may restart the app as soon as you kill it).
If none of that works I would wipe and re-install the rom or another rom for testing purposes.
And if it occurs on multiple roms/kernals it maybe hardware/battery related.
i believe you shouldn't charge it with a PC usually. i could be wrong though.

Nothing wrong with charging via a PC. It'll just charge a lot slower.

Not necessarily - in my experience it depends on how much power your computer's USB ports are capable of providing, and even that can vary depending on what controller is powering what ports and the like. I normally charge my phone from my computer and it takes roughly the same time as using the wall charger, though I've noticed that it doesn't seem to charge as quickly on at least one or two other computers I've had the phone plugged into.
USB usually has 500mA, where as the charger supplied by Samsung has 1000mA. It -will- charge faster with the supplied charger.

That is still sufficient power to run the phone without the battery. So at worse, the battery stays at the same percentage. It's not normal for the battery to drop while the phone is plugged in.

Higher powered USB ports are far and few inbetween. Usually higher end PC's/controllers will accommodate this. Most PC's though only push about 500mA via the USB ports.

once in while my phone will bug out like that, even if you turn it on and off. only way to really fix it is a battery pull.
I have found that if I am doing anything on it (screen on, gaming, Internet, etc.) and connected to my laptop, it often will not have enough power on the subject to compensate for what I am using and will only slow the speed the battery decreases.
That's crazy. Try a factory install. Another possible point of contention, lock frequencies and stop all overclocking. On custom Roms is your clock/governor settings set in the rom OR an app? If you have both set to boot they could be conflicting and constantly switching clock speed and governor settings.
Another thing to do. Charge to 100%. Go into recovery and delete your battery stats
yeah.. that's happened with me while pc usb charging. i was running maps, playing music, and texting at the same time with the screen constantly on. at first it was a slow drain.. then if i turn the screen off it would charge.. just too many things at once. but governor, voltages, schedulers do play a factor.
I don't think you guys realize. I don't have a single app running. At lunch time today I basically had 95% charge on my phone -- and it was connected to my computer.
In about 5 hours the ONLY thing I did was send a few txts. Sent maybe 20 txts in 5 hours. The ENTIRE time my phone was plugged in.
My phone is now at 84% and it's super hot. Opening battery to see what's up? doesn't show anything using any battery juice.
This phone fuking sucks.

This only happens while charging via PC?
What is it that's getting hot, the very bottom of the phone or the battery?
Have you tried going to retail store with this problem and see if they swap out the battery for you? Might just be a faulty battery.
Have you tried different PC's and/or different usb cables?

I just had the same problem with my brand new stock Galaxy S4.
I bought the new 2amp Genuine Samsung car charger and on the 1st use with my phone turned off it took 3 hours to charge 49 % battery and when i turned the phone on it would say it was charging but the battery was going down.
Faulty cable. Used the car charger with cable provided with phone, all fine. But the Galaxy S4 with auto brightness even with the genuine wall charger if you are playing games it takes ages ti charge and sometimes won't even charge and loose battery.
Just use the genuine charger and try not to use the phone while charging.

Does it take long to charge the battery? Like the nexus s. If its a slow charging phone like the nexus s then im not buying.
didn't think that fully charging it toke that much
i usually leave the phone charge when i go to sleep
removed from a 100% charge at 9:15am GMT
I own Nexus S too and experience the same, slow charging ... using the charger from Samsung (default).
So, I changed the charger and I use the one that came with the HTC Desire
And it is much faster, like 3 hours to go fully charged compared to more than 5 hours.
So, there you go, change your charger!

I can usually get my nexus S to a full charge in an hour or two, depending on how empty I let it get. It's fast enough that if I've forgot to charge & need to go out a 20 minute blast will get me through the evening.
No idea who made the charger.. I've got a house full of the damned things these days
So what about life time?
Just check your chargers mA output, the higher the nr, the faster the charge. A computer USB port outputs 500mA wich gives a rather slow charge normal mA on chargers is around 700mA -> 1A. Keep in mind though that higher mA resulting in a faster charge puts more stress on your battery and it WILL get hotter, to high numbers can even damage your battery so be carefull and monitor your batterys temp when trying a new charger!

Slightly off topic, but regarding charging...
Does charging via a "weaker" USB port damage the battery? For example, at work, the only USB port available is an old iMac keyboard USB port, and it's "weaker" in the sense that when I connect it to my phone, the computer tells me "A USB device needs more power.... "
I understand this might charge the battery slower, but does it cause any damage to it, short or long term?

As far as i know USB before 2.0 needed external power supply, meaning your device should not be able to charge from this type of USB. But to answer your question, no, you can not damage an electric device by undervoltage or lower Amps.

Like to see and test how the charging is with different chargers.
Have seen slow charging ( also better hold out ) with different chargers.
My best charging is stil with the original desire ( charges quick and battery holds longer ).
Galaxy S plus is slow, wildefire also slow...
So right now I've got my phone charging off my wifes macbook. I've installed the % battery mod so I can see how much juice I actually have, and in the last 20 minutes of use its actually gone DOWN fron 11% to 9% while ON the charger.
Wtf? I'm on wifi with screen brightness on max, but shouldn't it still atleast maintain the original level?

Probably, can't stand it any less than 1/3rd
A laptop can't put out enough power to charge the phone under use. Especially if you're using LTE. You'll have to use a wall charger.
Same thing happens when you surf using wifi while plugged into the wall, I made a thread about this two weeks ago.

Mine does same, GN is crap in this way, my iPhone 4 could easy do that.
on my Thunderbolt & Rezound, the phones would still charge via "Charging USB" while connected to PC even during tethering... so long as i was just doing simple web browsing. If i tried to download something or do some online gaming, then the battery would go down.
I found also that if i had them charging in my car, also in "Charging USB" mode & streaming music to my stereo via AUX, it would also lose power.
The same exact thing applies to this Nexus also. However, if i have it plugged into PC and do wifi tethering instead of USB tethering(much slower data speeds), then i can download/game and it will actually charge... just very slowly.
As for the car, if i use an actual power inverter so that it will stay as "Charging AC", then i can stream/download/etc and it will charge up normally.
I have some USB cables that have a mini-USB on one end & split off into 2 USB-A(male) connectors on the other end. they are intended for external Hard Drives that need more power then what just 1 connection can supply...
i think i am going to modify one & replace the mini-USB connector with a micro-USB and see what happens.
this is so simple.
if charge equal usage=charge will be 0+/-%
if charge is greater than usage=1+%
if charge is less than usage=1-%(batt drain even if hooked to pc or laptop or wallcharger)
not actual charging numbers. but just a figure on how it works,
this also counts for the wall charger.
So my s2 has been charging really slow, like today it took like 5 hours to fully charge, and when connected to charger if I'm using it it wont charge very well, like the battery will stay at lets say 20% when im using it and charging it, it might even go down more. it used to charge pretty well even if I was on it. Cuz this be the charger, or is my battery messed up?? Im using the charger that came with the phone.

Are you charging through a usb port on your computer or ac? If it is with usb port then yes it will charge at a much slower rate. Also if you have a lot of apps running or backround data going it will also cause your charging to slow down some. I would say through usb without any apps open and backround data stopped It would take a few hours to charge say from 20%. Through AC in the same condition probly 1.5 hours. Try to reboot your phone and then plug it in to charge to see if that doesnt speed it up any. If it does then you know you have backround data moving at a fast rate and that would be your reason to slow the charge down.
Yeah I'm charging with the wall charger, not thru usb

You could try calibrating the battery, maybe. To do that, turn the phone off. Charge to full (make sure it's full, by taking it off of the charger and putting it back on...the indicator should read 100% almost immediately when reattached to power).
When the battery is full, with the phone still turned off, remove the battery for about 2 minutes. After 2 minutes, reinsert battery and restart phone.
Battery will be calibrated. This may not resolve the problem of a slow charge, but will clear 'battery memory' which may have been preventing it from charging completely (and, I suspect, may have inhibited charging).
Good luck!
I was using an aftermarket wall charger and had similar results. Switched to the USB/AC converter that came with the phone and all was well.

Hey elflip88, have you found the issue yet?
I have the same problem on my HTC Amaze 4G. It's charging 1% every 3 minutes (adds up to 5 hours)
I'm also using the wall charger...oh damn, I'm starting to think I have a faulty device / battery...
yelp!
For the record Samsung devices are known to be slow at charging so with that considered.... You still shouldn't be at 5 hrs. I would find a battery stats app charge your battery over night and check the chart to see exactly how long it takes to go from 0 - 100. Make sure your batter status is good. Also check the voltage coming into your phone from your charger. There are plenty of battery stat apps in the market that will do this sort of thing. Of course make sure your battery doesn't have water damage of course too lol.

I've had the same problem with mine. But, I can get 1.5 days without charging and moderate usage. Charge it up, drain it, charge it back up then wipe your battery stats in recovery.
This may help if you're using an aftermarket wall charger
If you guys are having issues with slow charging using an aftermarket wall charger, it could be that the phone is charging in a USB state rather than an AC charging state. QuickCharge could alleviate your issues. The cable is inserted between the wall charger and the USB cable that goes to your phone. You can find the product on Amazon. It's the 2nd of 3rd item from the top when you search 'QuickCharge'.
I find that when I fully drain my battery and charge it, it's really slow. Once the phone has enough battery to stay on, I unplugged it and replugged it and it charges normal again.

It's your wifi and your apps using wifi. Turn wifi off while charging. I used to charge 4 hours + on my S2. Reduced to 2 and some change when I turn off wifi.
Also, I struggle to make it through a working day with wifi on. Turn wifi off and I can do 4 days no problem.

When I first got this phone I noticed it charged pretty slow. 5 hours to get to full from 0% but it then got a lot worse. Over night it would only charge from like 18% to 41 so I got a new charger and wall adapter and that seemed to fix it for a couple days but now it is charging slow again. From 70% to 100 it takes about 6-7 hours. Anyone else experiencing this?
The only time I've heard of that happening is when people fail to 'condition' their lithium battery properly before normal use.
In other words, upon getting your new phone, and/or battery, you're suppose to allow your battery to fully discharge and then fully recharge 3-5 times to condition your battery before plugging it back in half way through discharge.
It's usually what the carrier sales clerks are suppose to tell you when purchasing a new smartphone.

Just sounds like a bad install of something. I would do a factory reset through the stock recovery, and make sure to wipe dalvik cache.
My phone has started charging slowed as well, but mostly when connected to the computer. I made sure my usb ports were set to not allow the computer to shut them off to conserve power and it seems a bit faster. As far as charging and discharging ect ect I don't do that and never had a problem with slow charging and even the couple of times I tried it, the battery life never really improved. So think it is needed and some think it is a waste of time.
Charging via a computer USB port will always be slow when compared to the higher current capacity of the included AC charger. Computer USB ports have a lower current rating.
Make sure your using the charger that came with the phone, not all chargers are created equally.
There's also been some talk about the quality of USB cable being used, but I haven't found that myself yet.
Little bit of info...
I have tried numerous chargers while at work here (Technician) and there are some issues.
Samsung is funny on which chargers it accepts. Very funny.
1. Stardard charger that comes with the device will charge best. (Obvious I know) Using wall charger. (Full charge in 3.5 to 4 hours from 1%)
a. Using USB end plugged into PC while charging takes typically from my tests double the time to charge. (I'm guessing that data connection to PC is slowing the charge. (Full charge in 6 hours from 1%)
2. 3rd Party Generic charge cables (usb cable only) still charges device however stardard power draw is lower and does not charge in a decent time period.
a. Some 3rd Party usb cables plugged into a pc showed charging however they did not keep enough of a draw to actually charge my phone. I lost battery instead of gaining.
3. LG chargers did nothing for me. Couldn't get a decent charge.
Motorola chargers gave me the best charge besides the original.
Chargers with replacement tips... what can I say. They didn't seem like a good idea and weren't. I had too many issues and at times had some overheating issues. Luck of the draw me thinks.
3rd party wall chargers were hit or miss. A few did seem to give me a decent charge, others gave me a very slow trickle charge taking anywhere up to 8-9 hours for a full charge from 1%
All in all... it's a crap shoot using 3rd party cables. It's all based on voltage output and Samsung likes to change things alot. You will still get a charge but who knows the length of time it will take.
Oh and car chargers... typically only good for keeping it at the same level you plugged it in at for short drives. Long drives obviously work much better.
Hope this helps.
About charging: I have noticed that micro USB cable that come with S3 is really bad - it is loosing a connection to PC,and, beside that, I have noticed several times slow phone charge... Accidentally went to settings- battery - when I was on AC charger and saw in settings that phone is actually charging in USB mode!!! Wtf??? Disconnect usb from bottom end (at charger side) and reconnect and then on phone says " charging - AC" ... So,conclusion is that you check your phone charging status when you put on charger,maybe it is charging in USB mode and because of that phone is charging slower than it should on regular AC power.
The only battery issue that i have noticed is when i use my computer to charge it takes forever but when i use the factory wall plug and cable it charges quickly with no issues

Very slow charging with OEM charger.. i9300
This is a fact. The OEM wall charger surely has some issues. Though 1amp output, as claimed on th specs chart, my i9300 charges super slow. From 80% to 100%, it takes nearly 3 hours.
So, i switched chargers and used my S2 and Note OEM wall chargers. And voila, the phone charges super fast. I even ordered a new OEM charger for s3 with the data cable included and the same issue occured.
This has worsened ever since the JB update. So I am now using the S2 charger and very satisfied.
SWTICH OVER GUYS!! OEM charger is useless,,,
I have had my phone on USB to computer charging for 7 hours, with a one hour break to watch Dexter. I was at 18% and I am now at 69%. I think I will have to use the wall adapter because this is just ridiculous.
Usb to pc will always be slow buddy. It outputs 500ma while d wall charger is 1 amp
I found my Usb cable faulty. Sent for replacement.

Without reading all the post. I have had this same problem. Took phone to sprint, they tested the battery and it was bad. Got a new one and good to go..
I just got a t-mobile version of the S4 and I'm loving it, but I noticed it is very very slow to charge.
Aside from light to medium usage i didn't touch it much between last night and today. I had it plugged in and charging via USB, but it maybe charged about 40-45% in 6+ hours. My old phone (LG G2X) never took this long to charge.
More Info;
This was using the Stock T-mobile Rom
I have since rooted and installed CM10 nightly on the phone, It appears to suffer the same issue
Between 9:27 to 10:00 it went from 67% to %74, My LG went from %39 -%56 in about 20 minutes. By those quick number it will take 7 hours to charge the S4 while only 3 to fully charge the g2x
Is this normal? is there anything i can do to fix/test or alleviate this?

The question for you is the source? If you plugged it into your compy, it will take forever as standard compy USB ports (USB 2.0) provide only about 500 mA. The stock S4 charger is 2 Amps.
The fix, plug the phone into the wall using your stock charger. If it is still slow, it is probably your battery. Good luck.
Make sure to use the charger that it came with. Ever since I started using the stock charger my battery charges fast. Also it could be your plug so test it with another just in case.

Yup it was the charger, I have chargers pretty much where ever i go so i just used those. With the stock one it works great but i ran into another issue. I plugged it in and it was taking a really long time to charge with the stock charger, something like 3% in 30 minutes. I had to unplug and plug in the cable again and it charged normally.
Is this something I should worry about?
It could be possible that the cable was not properly seated in the phone, or the charger end was not properly seated in the wall cube. I wouldn't lose sleep over it unless it happens often. Could be a phone problem, but sounds like a one off to me.
Yea my lady like to use my charger with her HTC phone because it "charges faster". The S4 stock charger has the highest amp rating and provides juice at the highest rate to any device. :good:

I just got a t-mobile version of the S4 and I'm loving it, but I noticed it is very very slow to charge.
Aside from light to medium usage i didn't touch it much between last night and today. I had it plugged in and charging via USB, but it maybe charged about 40-45% in 6+ hours. My old phone (LG G2X) never took this long to charge.
More Info;
This was using the Stock T-mobile Rom
I have since rooted and installed CM10 nightly on the phone, It appears to suffer the same issue
Between 9:27 to 10:00 it went from 67% to %74, My LG went from %39 -%56 in about 20 minutes. By those quick number it will take 7 hours to charge the S4 while only 3 to fully charge the g2x

There are a few factors here.....
1. The charger itself. The original Samsung is a 2A charger. If you use a different one (most are only 1A) it will take twice as long to charge.
2. The USB Cable. Believe it or not, not all cables are the same. With the standard charger and cable you will be able to charge @ 1900mA. Less then 2 hours to fully charge a completely dead battery. But.... plugging some USB cables into the standard charger will limit the charge down to just 600mA.... taking 3x_ longer to charge.
3. The other is the kernel. If you're using a newer custom kernel Samsung has limited to a max of 1200mA with the screen on & full 1900mA with the screen off.
Lastly, you can download an app on the playstore called Galaxy Charging Current. This will show you the charging rate should you want to test your setup.

This man speaks the truth. I use CurrentWidget and set to manual update. Whenever I'm testing cables/chargers, I plug in a known good cable (charges at 1900) to see what the charger is putting out. I do the same with a known good charger (2A - iPad and S4) and test the cables
