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
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.

Guys this issue is annoying me. My device is having some charging problems. I have measured the charging time for last two charges, and its taking 3 hours 40 mins for 10% to 100%, and 4 hours from 0% to 100%. Where most people are saying it takes around 3 hours, from a complete drain to full 100%.
So have any of you guys ever measured the actual time of charging? A lots of comments I see say around this or around that, or from 2 hours to 3 hours, well that's not what I need. If anyone has measured the time then please post here. I'm thinking about going to SC, but I don't wanna go there until I'm totally sure that there is a problem.
PS: I'm talking about Stock charger, (2A) plugged in AC power source. And device should be on, not off.
Btw- There should be a technical answer to this, the charging current is 2A and the battery is 3100 mAh, so how could I do the math?
Thanks in advance.

I don't know the math stuff but why don't you try calibrating the battery - worth trying !
Knowing that info is only half the truth. How the phone charges the battery and how much energy your phone uses during the charge matters too.

The time taken to charge is a pretty simple mathematical formula. But the rest of the calculation is complicated.
If you phone is on, how bright is the screen, is the display on or off, are you on wifi or network data, are you syncing email every 15 minutes or every hour, are you using the phone to send messages during charge, have you got gmail, dropbox, facebook, instagram, whatsapp, etc etc etc all doing a sync at regular intervals during the charge?
All of those things will use up some of the charge as its going in, so the charger is fighting against you.
I've been charging off usb at work and struggled to gain 20% in 8 hours because of my usage pattern.
Theoretical time for charge is about 1:30 hrs. Reality, start and ending charge should slow down (for safety), heat slow downs, plus usage of phone as spoken above I guess it could take up to 3 hrs.
It's not great to do a full charge regularly. I tend to keep mine between 40-90% for maximum life cycle of battery.
Perhaps try resetting battery stats? Try a different 2a charger?

Mine takes 2.5 hrs to charge from 10% to 100% with phone on using stock wall charger and cable (when charged continuosly with no activity on phone). It charged from 1% to 96% in 2.5 hrs with phone switched off (switched it on exactly after 2.5 hrs to check). But, usually i avoid charging my phones to full 100% (also always charge it when at 10%).

Try with another note 2 charger first. The thing with these chargers is they will behave erratically when there is voltage fluctuation or if you use in a train and other cases. So go to SC and tell them its taking almost double time for me to get charged. They will replace the charger as well the cable. My cousin has the same problem with s3. He got it replaced by the SC.

Thanks Chaitanya. But the SC guys are so stupid here. First thing they do always are to take the phone in their custody and deal with it badly. Still I will ask them to replace the charger and check.
Some of us have noted that if you let the screen time out and not manually shut screen off after connecting the charger. ..The charging is faster. . If you manually shut off the screen. .. The charging is slow.... It is weird but don't know why. .it definitely is happening

Op: I said theoretical it will take 1:30.. Realistically it should slow down during stages due to safety reasons.
Mine took probably 3 hours the other day I ran it down, but this was combination of using 1a and 2a charger.
I think on the note 2 it doesn't ramp up power till it gets to 20-30%. Took a while to get there from 2%. If only battery widget was working on the note 2..then I could confirm.

Are you using the charger that came with Note2 ? I was using my old blackberry charger and it took for ever to charge the phone.
The output of the Note2's charger is more than twice the output of my blackberry charger.
^ Yeah, of course I am using the stock charger that came with Note 2! I'd not create this topic if I had used another charger.
Anyway, after a long week in Service Center now my phone is back, they provided me a new charging adapter (not the cable) and I was very happy because I thought everything will be smooth and like before but guess what? No improvement. It's still taking long! I just measured it for 30 mins exactly, it went from 70 to 83%, i.e 13%, where it should be 24% as stated in this thread,
http://forum.xda-developers.com/showpost.php?p=33585646&postcount=31
Now I am really angry. I will try with another Note 2 USB cable first, if that fails, there is something wrong with the device, I guess?

I really don't think it's your device or your battery for that matter. I have a question as well (sorry to hijack...). When you were charging it for 30 mins, were you using it? Was the screen off or the phone totally turned off? I noticed one night that I had an email notification and the phone did not charge because the notification LED was on all night while I slept and it was plugged into my 1A Samsung charger from my original Note. I have yet to check if the charging disconnects itself if the LED comes on. I don't even know if the phone charges at all if the screen is on either. Can anyone confirm? I guess I'll try it out tonight! The battery last forever I got to admit, perhaps most of the time I'm slow charging it at 1A max with the original Note's charger? I guess it does the battery some good
Thanks a bunch!
No pal I am not using the device while charging (because I am testing and measuring the times, that's why I restrain myself from touching it), and it's on, not off.
Anyway, yesterday I went to a friend's home and found he has a Samsung ACE and has same USB port like Note's and I was carrying the charging adapter, so I took that Ace's cable and plugged in to my Note's adapter and let it charge for an hour, and I was amazed and happy to see that it increased 38% in 60 mins. Well this tells me that the USB cable of my Note 2 is gone to heaven.
And oh, if you charge and use the device at the same time it will charge pretty fast even then too. I can confirm this when I first got the device, always was using it and charging, and I was surprised to even then how fast it was charging.
I (and many other users) have similar problems with Galaxy S3. I've made an app that shows the actual charging current: http://forum.xda-developers.com/showthread.php?t=2076078
I'm not sure if it works on the Note 2, but it is worth a try.
Please check if your device is charging at the optimal charging current (I think it is 2000mA for the Note 2 charger, instead of 1000mA as pointed in the SGS3 thread).
I currently have the CM10.1-M3 build from 4/17/13 installed.
For a long while, I have been having major issues charging my Captivate Glide.
My original battery died. It was bloated. I called AT+T and they sent me a replacement. I also bought two high capacity batteries.
If I leave the phone charging about half the time little or no progress is made charging. Lat night I charged the phone for over 8 hours and the charge went from 10% to 14%.
Other times I will wake up after charging it all night and it will say fully charged, but then the instant it is unplugged from the charger, it will drop down from 100% to 20% or less.
Then once every 3 or 4 days it will actually fully charge. But even in that case the charging is slow at best.
I did a full wipe and re-flashed last night and nothing changed. I have tried charging in airplane mode, but that seems to make it worse. I have had a little tiny bit of success turning mobile data off, but otherwise I have tried everything I could think of with no luck.
Has anyone else experienced similar issues, or have any suggestions? Is this a case where I might need to replace the phone entirely?

I have tried a few different chargers. I mostly use a 2.1amp wall charger. I also have a 1 amp wall charger, and a 1 amp car charger. I have tried about 3 different car chargers.
I am really suspicious that the micro-usb port on the phone went bad and that I will need to get the phone replaced.
Charging with AC is gonna be alot faster then with DC. But as far as it being the rom I don't see tthat.. sounds like possibly a loose wire or bad connection when u lay ur phone down

Charging
Hello,
When I charge my Captivate Glide with phone powered up plugged in to the wall, using the supplied wall charger, I've noticed that the battery seems to drain quicker. This is with the original battery, I will be getting an extended battery for my phone. If I power the phone down then charge it in to the wall it charges quickly and seems to take longer draining. This does not happen when charging with the PC.

Bloated battery could just be bad - but it could also be due to overcharging. That's not going to happen unless there is a serious problem with your phone, or possibly a problem with the contacts leading to an incorrect voltage reading. This also may explain your problems charging and sudden jumps in charge %.
Clean your contacts well on the battery side and phone side with a pencil eraser, rubbing alcohol, etc.
I notice a big difference with whatever kernel is shipping with the current M3 cm10.1 build between a 500ma charger and 2amp charger, so I imagine the kernel is set for a 750ma or 1amp charge.
Is everyone really getting the 50% charge in 30 mins? It feels like I am getting about 1% per 1 min of charge time on average. Not sure if that is normal or I have a defect somewhere? Also, is fast charging safe to use for every charge session or is it meant to be used once in a while for emergencies? Thank you.

I used to get those insanely fast charge times; however, recently my phone has been charging slower (with fast charging on). Not only that, but, for some reason, the original wall adapter stopped working twice now. The first time it freaked me out because I thought my phone was messed up, but it turned out that everything was working except the adapter. Then later, I found out that if I reboot my phone with the adapter plugged into the wall, the charger will magically start working again! This worked for one or two charges. Today, I found that my phone was, again, charging extremely slow. Not only that, but my phone stopped charging after around 50% and the adapter is broken once more. I've tried the reboot thing three times and it didn't work again T: So now I'm kind of worried my phone might be defective?

Although I am fairly certain that my issue was the wall adapter portion of the charger, I just found it strange that the fast charging function failed to work properly around the same time when my wall adapter started to fail. Hopefully I am right and nothing else was wrong, but I thought that I would say something in-case I was wrong
As for getting it replaced... I bought my Verizon Note 4 at BestBuy off-contract and when I went there, they claimed to not have any in stock. They never really bothered to ask if I wanted to replace it even though I brought all my receipts and junk so I just took that as I wouldn't be getting a replacement haha :crying:
If anything I'll probably end up just buying another fast charger from samsung later, but for now slow charging is fine I guess. The fast charging did make both my device and charger hot, so maybe that was the problem?
edit:
I do not have any other quick charging devices (to my knowledge), but the wall adapter - combined with various other cables - continued to fail with my other phones as well.

Do you know if it's safe to use fast charge for every charge up? If it shortens battery life over time, I'd like to know this now and only use fast charge sparingly.
Yes. It shortens battery life. By using the only charger they give you, you essentially cut your battery life in half. It's a conspiracy by Samsung and the makers of the materials used the batteries

Pretty sure that was sarcasm. I'm less sure about your comment, though. ;P
I read it in American Android, first December issue. They did a study. Only way to avoid the battery dissipation was if you only used the fast charger at night, and Sundays after noon, but before 1pm PST. fascinating article. It's amazing what a group of students at Yale who love Android can actually accomplish.
I think I can work around that charging schedule. I am also going to subscribe to that magazine now.
HI can anyone tell me if there is any way to resolve this. I think is has started since doing the upgrade to Android 10 earlier this week.
I normally put my phone onto the wireless charger before going to bed and I have noticed recently that when I grab it in the morning the battery percentage is sitting around the 90% mark. I initially thought the charger was not able to charge to 100% but on further examination I see that it indeed charged to 100% after I placed it on the charger and then the charging stopped and the phone ran on battery until I removed it in the morning.
I confirmed this this morning by replacing it on the charger and watching it charge (like watching paint dry ). The charger light was blue while charging, when the phone hit 100% the charger light turned to green but after about 30s it completely switched off and so too did the indication on the lock screen that a charger is connected. Removing and reseating the phone started charging again.
It definitely looks to be software related as I did not have this problem last week. I just wanted to ask if anyone here has noticed this and knows of any workaround?
For the record I am running fast wireless charging with the samsung wireless charger that came with my wifes S8, that charger works perfectly with my older Note8. I have also tried switching to normal wireless charging speed with no success.

I normally put my phone onto the wireless charger before going to bed and I have noticed recently that when I grab it in the morning the battery percentage is sitting around the 90% mark. I initially thought the charger was not able to charge to 100% but on further examination I see that it indeed charged to 100% after I placed it on the charger and then the charging stopped and the phone ran on battery until I removed it in the morning.
I confirmed this this morning by replacing it on the charger and watching it charge (like watching paint dry ). The charger light was blue while charging, when the phone hit 100% the charger light turned to green but after about 30s it completely switched off and so too did the indication on the lock screen that a charger is connected. Removing and reseating the phone started charging again.
It definitely looks to be software related as I did not have this problem last week. I just wanted to ask if anyone here has noticed this and knows of any workaround?
For the record I am running fast wireless charging with the samsung wireless charger that came with my wifes S8, that charger works perfectly with my older Note8. I have also tried switching to normal wireless charging speed with no success.

Unplug the charger from its power source and plug it in again, causing it to 'reboot'. Let us know the results. Note, there is an option to set the wireless charging to NOT be fast during certain hours of the day. I set mine so it charges slowly while I am sleeping - to put less stress on the battery. Your charger may be a little old as well if you got it with a note 8 or S8 - ?

IMO this is a good feature to stop the wireless charger cooking your battery.
Maybe turn down your AOD brightness or something, to use 10% within a couple of hours of being idle is pretty high. Maybe turning off fast wireless charging would extend the charge time so it finishes nearer to when you wake up could help too.
Thanks for the feedback however it does sound like workarounds for an issue that should not be present (apart from rebooting the charger which I will try when I get home).
For me wireless charging should act just like wired charging in that when it reaches 100% the phone should essentially run off the charger now and not use battery at all. Every other phone with wireless charging that I have had worked that way, this is just plain stupid.
Willhemmens its not a couple hours, looking at the battery graph if I go to bed at 10pm and put the phone on the charger it pretty much hits 100% around 11:30 and then is at 90% at 7am, so it is 10% over 7 hours which is ok in my books, but reality is that during this time the phone has another source of power that it can and should use. It did before I applied the Android 10 update.
I have had this issue every now and again, and I found that rebooting it takes care of the issue.
An update. This morning I tried my wife's wireless charger and when the phone reaches 100% it continues to show the charge icon. Put my wife's note 8 into the wireless charger and it exhibited my problem.
So it looks like this is a problem with the wireless charger and not the phone.
Thanks for the answers guys I am of to try buy a new wireless charger
edit - New charger solved the problem.
