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

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] Battery drains when on the charger

Hey this is my first post so if this question has already been asked I apologize ahead of time. Well I put alot of different themes and roms on my phone, but recently I have been noticing that my battery will start losing charge on when I have plug into the computer and wall outlet. I have not been able to find a fix for this anywhere. Please help!! Thank you everyone on here you guys are awesome

I believe only the case the battery drains faster the charging speed would be when you play games (lots of cpu + screen). It happened one time when I played Angry birds games...
But, even you installed thousands of apps, usually battery would be fully charged within maximum 3~5 hours and this speed is enough to overcome the battery drain speed. Please check below thread and I added some comments in the last post.

Thanks kobridge I will check it out. But yea the battery drains even when I just have it on the charge idling its pretty weird hopefully I fix it cuz I already voided the warranty a long time ago lol

I think it's almost usb cable problem (charger).

I had this issue before. The generic charger would only charge when screen was off. Bought a new charger and charges fine, even when playing games(just gets hot if playing games).

Am I damaging the battery?

so I got Need for speed for my Xperia S (great game by the way, would recommend) the only problem is it is un UTTER battery drain, I'm talking rapid draining even having the screen brightness on low. Do you think the battery is getting damaged by my heavy use in this way? I'm charging it to full, playing it for a good hour and then it needs to be recharged so I plug it in.
cheers

No you are not damaging the battery. Hd games drain your battery. Dont worry it happens with every phone. Please post questions in question and answer section.

How about if I play while the phone is charging, does this affect it in any way, like how with a laptop you should take out the battery if its plugged into the wall to extend the battery's life?

No it wont affect your battery...I have been doing that for the past 10 months

It's a difficult question. From one perspective it's better to keep the phone plugged in because a Li-ion battery has a finite amount of recharging cycles. The worst thing you can do is to completely discharge your battery, then completely charge it again and so on several times. Which is what you've been doing and these are wasted recharge cycles.
But constantly charging your phone will also make it hotter and that combined with an intensive game will make your phone too hot, which might result in some components overheating and a reduced life expectancy.
So I'd advice to keep your phone plugged in if possible, but don't play for hours.
When you compare to laptops, it's indeed better to remove the battery when you're plugged into the wall (keep in mind that the battery doesn't lose its charge though, there's nothing worse for a Li-ion than being completely empty). But there's no phone you can run without a battery so you can't do that . It's also a question of luck. I never remove my laptop's battery and it still easily lasts 2 hours after having it for 2.5 years and using it a LOT (when plugged in mostly). It was just a cheap laptop with a 6 cells battery. Most of my friends that have a laptop that old or older (and also more expensive) can barely keep it charged for more than 10 minutes now.

No,
nowadays you can't damage your battery in any way as I know.
But it is recommended to charge your phone to 100% and turn all notifications off then let it on sleep mode till your Phone is going off by itself.
This doesn't improve the Battery lifetime or something like that but it is recommeded

thanks for the advice everyone

S3 Battery Drain

Hi, I had my galaxy S3 from Rogers for almost 1 year and the battery drains like crazy!! When I first got the phone the battery life was ok. It lasted 1 full day (with the settings auto brightness, wifi usually on [when not in wifi area, using LTE], vibrate only, power saving on and snyc on. I turned off gps, bluetooth, location services, and motion). About 6 months ago I dropped the phone in water :S and I got it repaired. The phone battery life was still about 1 full day (with the same setting as above except when I'm not in a wifi area I use 4G to save battery life). After that every month the battery life seems to get worse from 1 full day to about half a day :S. After doing alittle research (this was around May/June) I found out Facebook was killing my battery so I stop using it on my phone then my battery got better (to about 3/4 of a day). But after that in July and August the battery life got really really bad, it will probably only last 5-6hrs. I honestly don't know what is wrong with it now. Is the water damage the problem with my battery drainage?
I'm running 4.1.2, never rooted and I'm running Nova launcher too.

Get better battery stats or gsam battery monitor to rule out a rogue app(s) first...

Maybe the battery cells are dying out?

I leave mine on auto brightness too, I still get around 24 hours on a charge, and between 5 and 6 hours of screen on time. My phone is only about 3½ months old though... Could be the battery??

Is it the original charger that came with the phone? And are u charging it from the wall or pc??

Ya I am using the original charger and original cable.. using ac supply, with plugged in wall...
The thing is if I reset my device ( which I have done 2-3 times) and after that, watching video/playing games/ internet surfing etc. With the charger plugged in, works fine... I mean it charges my phone battery fine. Battery is new. Checked its condition with battery monitor pro... it states its good.
But after a couple of months after resetting, I face the problem of slow charging, with my phone in use while plugged in... did a lot of search but didnt help out. Cleared dalvik and other cache.... nothing seems to be working.

[Q] How on earth can the device's battery decrease while charging?

Hi everyone!
As you can see on the attached picture the device's battery life was decreasing while charged, i was playing a game with 40% brightness.
Can someone explain ne this, please?
Thank you!

Depends on what game you're playing. Asphalt 8 while charging for me only slowly charges, 1% every 15 minutes or so. If the game is using more resources faster than the battery can charge, it will decrease.

Not sure if that is totally unreasonable. 40% is significant in addition to gaming with a game that requires significant power seems OK.

I have the problem sometimes of my nexus 7 losing battery while charging sometimes as well, but I never use my stock charger and don't know where my original micro usb cable is. I have found that different Micro USB cables can have a major impact on charge rate. When the Galaxy S3 came out I noticed that with the stock charger and stock cable, I lost battery anytime I used my phone even while charging. My suggestion to you is to install the app current widget and put a widget on your home screen to see the amount of charge your device is receiving while charging. Yes you cannot do this while in a game, but you can at least test out different cables and chargers you may have to see if maybe one of those hardware pieces is the culprit.
