Phone charging really slow??

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

thats pretty weird...have you tried using another usb cable?? maybe the cable is faulty?

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.

Yes, try Battery Calibration from the market. Only works on rooted devices, and follow instructions.

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

YODA? ^^^^

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.

I old suggest using a different outlet if you haven't done that yet.

[Q] Galaxy Nexus Slow Charging?

So Ive been having an issue with galaxy nexus charging, like sometimes this thing charges so slowly that it doesn't actually even charge it just maintains the same charge than before i plugged it in, if it does go up it's often about 1% every 5 minutes or more unless I'm fully not using it and it is just sleeping..
anybody else experiencing this? charging it in my car with the lower voltage has no chance at all of raising the % unless my phone is fully left alone for a lot of time.

Are you talking about using the AC adapter that it comes with or USB? USB puts out 500mA - the AC adapter puts out twice that.

it had happened before, not sure how i resolved it.. now its back the issue :S

enable fast usb charging mode (franco.kernel) and try charging through usb ..... how long your battery last once its recharged ....

[Q] Laptop Charges Faster Than Samsung Wall Charger Cube.

It seems like my phone doesn't like those Samsung charger cubes anymore...it charges with 37Mah while a computer USB port charges with 387Mah...I checked with a BB A/C wall charger and it charges with 787mAH
It charged perfectly before with the charger cube, why is it acting up now?
I'm in CM 10.1.2 stable build btw.

no :/ if the other charger is charging at 878mah that means it will fully charge less that 2 hours try it

GSAM BATTERY monitor says it is...
It's not the battery because I ttried it on another T989 phone
It's the charger because the charger is packing a punch with the maH
Reflashing the CM10.1 ROM fixed it, and when I restore with TB, issue happened again
I'm gonna reflash and not restore settings to see what happens.

[Q] Battery takes long to charge

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.
Sent from my SGH-M919 using XDA Premium HD app

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

Charging very slow!

I just bought the LG G3 ATT version and I absolutely love the phone! However the charging time on this device is horrendous compared to my Note II which has a bigger battery. Please help!

Are you using the stock charger and cable? If not, what is the Amperage of the charger you're using? Are you charging from the wall or your computer?

I get a charge from 10% to 100% in around an hour in the UK.

Anywhere from 3-5 hours. Also if i'm using the device while charging it almost feels like its staying on the same level, something that I haven't experienced with other android devices.

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?
