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?

I was testing how long it takes to charge, so I didn't even touch the phone while it was charging.

1:30 hours? Could you kindly explain how?
And I've wiped my device fully, also reseted battery stats.
One thing I'd to next is, I'll turn the device off and see how long it takes then.

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

Mine takes about 3 hours to charge fully from 15 %

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).
Hi,
Ive been having problems while charging my phone. Usually i charge my phone from 11 pm to 7 am and sometimes when i wake up in the morning the battery light is green and it reads as 100% battery charge but the moment i disconnect the wire it instantly drops to 30-50%. Is anyone else having these issues?
Are you stock?
I have not had this problem and charge pretty much same as you. I am stock rooted with a few apps disabled and only had the phone since October.
Try this app
Also I'm pretty sure you shouldn't let it charge for so long, it will hinder you battery life in the long run. At least that's what I have read.

Option 1 : Clear battery stats
Option 2 : Get a new battery and 24 hour charge
Option 3 : Let the battery DIE, drop it in the freezer for a few hours, then 12 - 24 hour charge it again. Doing this though MAY (not always does) cause the water indicator to trip. Easiest solution I found for that was I vacuum sealed my battery THEN dropped it in the freezer. No air, no moisture, no trip.

I would also recommend trying this app. I tried it out a few days ago and it does seem to help out quite a bit.
I find mine drops instantly to 99%. Even sometimes when I'm at 74% and if I don't use it at all, I will check back and it goes up to 78% :-/
Guys, I just bought my LGOG Pro and I've noticed one strange thing. First two or three weeks the phone needed a little more than 2h (2:15, maximum) to fully charge battery (from 5% to 100% most of the times).
Now I'm having to charge it for 3h to fully charge it, in the same conditions. Is anyone having this issue??
How much time is necessary for your LGOG Pro to get fully charged??
Thanks a lot!
Anyone?
2 to 3 hours sounds about right
But why would it change from 2h-2:15 to 3h in these few weeks that I've been using it?

Use a higher capacity charger. I use an iPad 1st gen charger. It charges the phone in an hour.
As for the small time variation in your chage cycles, that happens with android batteries depending upon the state of discharge when charging began and other factors, nothing to worry about.
That's not bad.
I, like you, just got my G Pro and I love it. The first time I charge mine it was 2 1/2 hours to full, but now it is about 3 1/2. I work at a business that serveries Helicopters and I have to take a lot of pictures for projects so I can drain a battery fast, and this is the first phone that can last all day without a quick charge at break and lunch time.
I left my 8.4 charged with the wall charger over night, in the morning I found it's only 94% full, this happened multiple times, and I also tried another wall charger it still happened. The battery chart shows it stopped at 94% (some times 95%) and never went up. Does anybody has the same problem? Is there anything wrong with the battery? BTW, the battery life is not good for me, screen on for only 5-6 hrs on about 30% brightness.

stock rom, not rooted. I doubt it's caused by any app, if in that case the battery should still be fully charged then go down, but it's not what I saw.

Yes that's exactly the same as mine. I contacted Samsung support and they suggested to do a factory reset to see if it's a problem about software, otherwise I'll need to file a service request.
This happens all the time. If I reboot the tab will then show 100%.

Let it run down to 10% then recharge. do this a couple cycles. You could also try a battery calibration app that wipes the stats and starts fresh.
Solved my issue a while back.
A restart used to fix my issue but now the tab will say it's 100% charged and then at some point drop 10 or even 40% randomly.
Something is definitely wrong with the battery on this thing.
it's not the battery, but the reporting statistics used that is bugging out.

I found the problem has become worse and worse, sometimes it just stopped at 30~40%, then I said "f*** it", opened the back cover, pulled the battery out and put it back, reboot. Left it charged during the night. The next morning I found it charged to 100% !! Will post back if it really solved the issue after some more cycles.

I simply let the battery drain to around 20% and then charged it fully. Ever since (1.5 months ago), it has been reporting accurate battery %.

But the problem was the battery could not be charged to 100%, even if I left it charged over night, in the morning it showed 30%.
Mine works 100% perfect on ND3..
I have tried to make it do somthing weird..
I can't see anything in the ROM coding so far that would cause this..
So over a week later and my battery has been perfect.. Stock rooted nai....
4hrs 40 mins of screen on too..
Hi. I dont know if anyone is still on this post but i have this device and ive had this problem for the last year. It would get so bad with all the discharges that my battery died. I bought another battery and replaced it. I still got -300ma when connected to a 1A chaarger. So i replaced the flexi usb port membrane in hopes that would do it but i only got to 100mA. I bought a 2.4A charger and the tab doesnt even recognize the charger is in. Cant really turn it for service because I rooted it so my warranty is void. Any commentary and opinion would be greatly appreciated.:good:
Hi
I've got a brand new htc M8 and enjoying it immensely, but there's one thing that's worrying me. My first three or four charges were very quick--an hour or so from 60-65% but over the last few days charging has become an ordeal. I've read numerous forums and tried a number of techniques, most recently discharging to 10% then recharging (which took nearly 9 hours). I went out this morning and returned with 85% remaining. Plugged it in and Dashclock forecast three hours and twenty minutes to regain that 15%.
I'm using the charger provided, but have tried a number of others as well.Any other ideas out there?

if u have samsung lg or any original charger in ur house test it i normally have 1:50 or 2hr for fully charged
change ur USB CABLE
FIRST THING TO DO IS
CHANGE UR USB CABLE IF IT DINT FIX
SECOND THING IS CHANGE THE CHARGER AND USE ORIGINAL CHARGER FROM ANY MANUFACTURER
IF AFTER THAT UR GETTING SAME TIME CHARGING ITS UR PHONE MATER NOT CHARGER
Do you have fast boot enabled?
If so disable that, then power off the phone for a few minutes then power it back on and try to charge.
My neighbor had fastboot enabled on his and performance and battery life always sucked.. after disabling that he saw a lot better results.
Is your phone being used while charging? Is it getting hot while charging?

But be careful when comparing charge rates, as the current drawn reduces as the battery becomes more charged.

Yes, but a bad cable or charger would be very low. Far lower than the norm. ?
The stock m8 charger is a 1.5 amp charger if your using a normal .5 - 1amp you'll notice a slow charge
