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've had the same problems using an aftermarket wall charger.

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

[Q] Phone loses battery % WHILE CHARGING? How is this even possible?

How is my phone losing battery while charging ? It's insanely hot too.

Did you try rebooting it?

yes

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.

[Q] ~4 hours battery life on standby after factory reset and new battery

Hi Guys,
Recently my USB charging port stopped working. I tried to clean the area and move the pin back up but nothing worked. I ordered 2 spare battery's and an external battery charger. At that point, I was getting 2-3 hours of battery life. Once I did a factory reset on my phone, I began to receive 4-5 hours of battery life, which was okay since I have 3 batteries. I've also ordered the part to fix the USB port.
My guess is that fixing the USB port won't solve the battery usage problem right? I've noticed that if I turn off my phone at 20% battery and turn it back in the morning, the phone is dead, as in battery is being used even when the phone is turned off, which is weird.
Is there any fix to this issue? What would be causing such battery depletion?
Thanks for the help!

how long has this been happening? new issue or recent.
try DLing disable service from play store. allows you to go into each app and turn things off thats running in background.
also, wakelock detector, lets you know whats draining your bat

If device is discharging quickly even when turned off, factory resets, kernels or other software tricks probably can't help. Replacing USB port however sounds useful. It may be damaged in a way that drains battery.

its been going on for a month now. The battery life has slowly gone down over the past few months but I don't exactly know when it became so drastic. What's bothering me though is that when I did a full factory reset and nothing was running on my phone, not even google apps only wifi and regular cellular data, I got ~4.5 hours. How does that happen on a new battery? That must be a hardware issue right?

Ah okay, so even if I'm not using the USB port currently, it could be linked to the battery drainage problem?

Fast Charging... Does not work anymore!

i had my note 4 for two months already and fast charging works impeccably fine till recent week that when i went to vietnam and charged it at the hotel which tooked 6hours to charge my almost drained (30%) phone. when i came home to my country same thing.. charging takes 6 hours.
would anyone know what the problem is?
note: fast charging option is checked. never overcharged the phone. i have an app full battery & theft alarm that alarms when the phone is fully charged.
hope anyone can help me。

Have you tried using a different usb cable since it stopped working? Maybe the cable was damaged? Just a suggestion.

There is a chance your charger is broken.
Try charging on a different fast charger enabled charger and see what happens.

Note 4 : New Battery Drains While Charging

Hi. I had noticed that my batts keeps draining even if it being charged while using it. I use my phone for navigation. Before, it never had this issue where the charge keeps the battery at 100% even if the screen and navigation is alway on. Recently, I noticed that even if the phone is being charged while being used the battery charge keeps going down. I had tried a few backup batteries but all has the same result. I thought that it was all bad batteries so today, I purchased a battery from Battery Plus but this has the same result, it discharges while being charged when the phone is being used.
It charges the battery to 100% when screen is off or not being used.
I tried to factory reset even Odin flashed the phone that I think could fix it but still has this issue.
I might soon conclude that it could be my phone that has a bad charging unit.
But, it charges the battery.
Anybody had this issue?
I would appreciate your feedback.
Thank you.

more likely its your charger, your cable, or the port on your phone that are limiting the current that your phone is getting.
what type of charger are you using?
also i have had this issue before but my usb port on the phone is starting to go. a switch to a quickcharge charger and a high quality cable fixed it for me.

Yes, thats because low quality or degraded usb cable or problem on usb port on the phone.
Low power charge mode, caused by any of the above, cant handle use and charge at the same time.

you are both right. my home chargers (AC) can charge the phone with lcd turned on all the way to 100%. only on my car that has this issue. so, i purchased a new car charger and it fixed the issue.
I appreciate the replies.
Thank you.
