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.

Actually, one doesn't need an app to calibrate the battery. If you follow the instructions above, the app is unnecessary. And the phone mustn't be rooted

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.

Charging time for my battery is pretty slow. I takes more than 3 hours from 10% to full! It doesn't matter if it is chraging with the carger or via USB. Is this normal with the Nexus? I had Htc Inspire 4G, and the charging took 2 hours top!
*if i use the phone while charging e.g. play some game, the battery is still draining instead of charging.

You should get better results with an A/C charger but I've seen some wall adapters still read as if its plugged in via USB. You can check by going to settings >> battery while it's plugged in and it should read A/C charging.

What is the max current (mA) the charger you use can provide? Divide the capacity of your battery (in mAh) by the charge current. That is your approximate charge time in hours. I believe most AC chargers can charge with 1A, so a stock GSM battery of 1750 mAh should take less than 2 hours from being discharged to fully charged. Mine does.
The behavior that the GNEX will discharge even while being charged with a non AC charger (including car chargers) when gaming/navigating is not uncommon.

I've been charging it with Alcatel charger with 400mAh output. I'll try with Samsung charger with 5.0V output which says it's equal to 0.7A because I don't have the original (I think i have used it before, but i dont recall that it was any faster).
Could be kernel related issue, since there is an option to "Fast charge" via USB and it's enabled?

its not likely a kernel issue unless you are on some experimental one, but you would be able to easily find out by looking at the forum cause others would have the issue. And if you didn't know the Fast Charge option is to make your phone think its hooked up to a wall port if you are charging from your laptop or if your car charger is only being used a usb port thing.

It's franco kernel, nightly 251, pretty stable from what i've read in the thread. Also, I know what does Fast Charge option do, but I thought that somehow it messed something up. While I was googling for answers, I found some forum, where was mentioned the battery chip that is regulating the power it's using to charge the battery could somehow get messed up. Maybe I have bad batt.
mine battery too takes 3 hours to full charge using stock samsung wall charger. I'm using stock rom and kernel.
Mines takes 1 hr 30 minutes tops with fast charge

That is because the car charger most likely did not short both the data pins out, therefore you notice the discharging phenomenon because the phone will only take in 500mA without the data pins shorted or with kernel fast charge enabled. How is 500mA going to keep up with navigation, GPS and all other tasks?
Beamed from Maguro
Also realize that your previous phones battery probably had a lower capacity than the gnex therefore coming from 2 hours, 3 hours isn't that bad for charging a bigger battery

As has been stated get a GOOD quality charger. I might be weird but both my car charger and spare outlet charger came from Verizon. At least when i have had something not work they have been more than happy to open another and fully test in store for however long it takes. Sadly, my last car charger broke and I am too lazy to get another, my solution was to use a car inverter since I charge my other devices regularly on long trips. Plugging in a regular wall outlet from, oddly enough Motorola, does the job just fine. Alas, the majority of chargers my coworkers leave out are for lesser phones and will not even register on my beastly Nexus.
However i think i damaged my charger (original 1Ampere samsung wall charger) when i've been in Malta (i'm from Italy) last August. Before the holyday my nexus charged in 2 hours or less. During the holyday the charger heated a lot more than when using at home and now the charging process lasts about 3 hours. Also, when i connect the charger to the wall (even if the phone is unplugged) i hear a low almost-ultrasonic whistle.
I hope the damage isn't the battery.

Thank you very much. And the effective result is really a faster charging? Does it works good or not?
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:

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

I feel the same about using the phone and charging when playing games. No idea how long it takes to charge it tho, doing it while i sleep anyway.
I'm going to go wireless charging but sometimes I'll turn my phone off and give it quick charge since it charges faster. I know some people don't like to do that though.
the first thing I would check is that the usb cable is plugged all the way into the mains charger. When I first got mine it kept saying usb charging is slow, please plug into a mains charger, which I thought was weird as it was plugged into the mains, but on closer inspection the cable wasn't all the way into the plug, so it was thinking it was using a pc connection. plugged it all the way in and it was charging like a demon then.
Same freaking problem. It discharges 100-0 in 6 or 7 hours, with 1:30 screen on time, and recharges 0-75 in three hours. Have you managed to fix it?

How long have you guy`s had your S1 before you started having problem with the battery? also do you game or use any apps that eat the battery or get the tablet hot as that is really bad for the battery.

I wonder if the battery went flat while you were not using it, was it turned off or just in sleep/standby mode.
John.
haha no its not the battery as i have already replaced it with a new battery and still the same. i think it was turned off.
so how long does it take you guys to fully charge your t800/t805 from 0 to 100% while the device is powered off?
From what i have read around 5 hours for the 10.5" for a full charge when in sleep mode, maybe a 4.5 hours when powered off.
But charging speed depends on an compatible charger and quality usb cable, full charge current is 1.75 amps according to my usb power meter on my T800

hmm, because mine takes 3 hours to charge 18%. eventhough am using a note 5 fast charger and also tried it with official tab s charger too no luck.????
the usb ribon arrived yesterday, so replaced it. still no difference.:crying:
Have you tried more than one usb cable, as it make a BIG difference, like 0.5amp vs 1.7amp you can have the best charger in the world but if your cable is faulty or poor quality.
Your battery could be bad (how long have you had your tablet?), or your battery power connector could be loose/faulty(mostly 8.4" S1), or you microusb port could have become faulty.
Also if you use a third-party charger it has to talk to your tablet in an language it understand or you tablet will charge slowly, there are a number of different charger languages Samsung has a different one to Apple, or HTC that is why an Apple charger might only charge your Samsung tablet slowly.
I recommend everybody gets an "usb power meter/monitor" they only cost around $10 and it allows you to see straight away how much power you tablet is taking from you usb charger and some brands can trick you tablet into charging at full speed on an Apple charger, I bought an Belkin 2.4amp charger and it was only charging my T800 at 900ma, I changed a setting on my usb power meter and now my T800 is charging at 1750ma

Hello
After suffering slow charging, like 700 or little more ma Controlled by 3ctoolbox, Im now using a rampow nilon braided micro USB câble.
Now allways charging first at 1750 ma and fall ingénieur slowly from 80% to 100%, like a charging perfect mode must be.
The câble was baught at Amazon and work fine untill now. Verry small prize and quality.

From what i have read around 5 hours for the 10.5" for a full charge when in sleep mode, maybe a 4.5 hours when powered off.
But charging speed depends on an compatible charger and quality usb cable, full charge current is 1.75 amps according to my usb power meter on my T800

surprisingly i tried charging it with a cheap 3rd party cable and it has charged 48% in 2 hours whilst it was powered off, so it should take just around 4 hours to charge 100%.
when compared to the other 2 official Samsung chargers which charged more like 10% in 2 hours. quite strange results

Your tab will charge at full speed approx 1.75amp from 0% to 80% and then the charge rate will get lower and lower as it get`s closer to 100%
So the first 80% charges the fastest and then last 20% takes a lot longer.
EDIT: 80% of an 7900mah battery is 6320mah So it should take approx 4hrs to charge from 0% to 80% with an 10% charge efficiency
