Well I need to know from you guys, it's not that I don't know, but need to reconfirm. I think mine is taking much lower now than it was. A full charge, say from 5% to 100%, with Stock charger?
Thanks in adv.

roughly 1 percent for 1 minute. should be charged in a couple of hours

Charging from 0 to 90% happens in no more that 2 hours I would say. from 90% to 100% the charging rate gets slowed a lot. So basically shouldn't take more than 2:30 hours from 0 to 100%.
Thanks guys. Now I remember it was 2 hours 45 mins for me too at first.
Today it took 4 hrs 30 mins. Reason? I'll say tomorrow, after confirming.
Jeez PowerAMP!

I rarely charge it to 100%, usually to 70 or 80%. much better for the battery in the long term
Any research or refrence for this longevity ? I heard its always better to charge 100% ?

Thanks man ! Really helpful article...

you are welcome. the general rule is to try to 1) avoid charging to 100%, really diminishing return the higher it goes; and 2) avoid deep discharge cycle. I usually use 40% of the capacity at work everyday, so charge to ~70% in the morning, use down to ~30% and then charge again. charging time in this range is rather linear, about 1 percent a minute

Yeah, it happened to mine too few days back. My Note2 went crazy, taking around 7-8 hrs to fully charge from 15%. So, i tried searching about the problem on google but to no avail. Did a factory reset with cache wipe and problem solved :good:. Now it takes about 2.5 hrs to fully charge from say 10% (using the samsung wall charger with phone switched on). I can only say that the slow charging was caused due to some software but don't know exactly which one? You may as well try the hard reset if anything else doesn't work out .
P.S : Btw i'm on stock fw with no root or mod! Only did some OTA updates couple of weeks ago.
Guys, we have a changeable battery and is already writed Inside to android that it won't charge to 100%, it just shows at 100% but really it is at 95%-98% that feature came with 2.2.1 update 2yrs ago.
And we can change the battery after 2yrs for 20-30$, unlike Nokia lumia users or HTC one x or iPhone users.

Yeah, thanks. But if you've Watchdog installed then you can see which app is going over threshold and keep running on background. And yes, this time, again, the culprit was PowerAMP! Uninstalled it and voila. The same app created problem for me when I had my S2, charging was pathetically slow, even I had to go to SC and they said battery is gone. But I didn't believe and asked a techy friend and he said it might be some app, and damn right he was.
Anyway, if anyone having the same issue like mine, that is, charging duration has increased with Stock charger, then install Watchdog (the lite version will do) and see who is the culprit.
I have no idea how a top app like PowerAMP could cause this! Jeez!

The same problem happen to me few days ago..during that that i was charging using extension cable where 3 pin plug is sharing with my note 2, laptop n tablet charging @ the same time..its take nearly 4 hour for fully charge the note 2 while im using n charging my laptop n tablet..but, from that i understand that when the connection all charging at the same time on the same 3 pin plug, the load are higher which decrease the current value (current drop)..that the reason why my note 2 charging slow..check if OP case is same like me??

Well I wasn't using the same plug point but the charger was connected to my Belkin Gold surge protector, where my whole PC and monitor is connected. Could that be a problem?

Is this long-charging-time problem a single occurrence or you are consistently having this problem?

I checked both wall chargers they have different volts of their input and output and theres no usb or anyting to take out of the jabar wallcharger is it safe to charge with?
When i plug it in it works but is it generally safe to charge this phone with it....
By the way The jabar charger is meant for a bluetooth headset
Thanks guys!
Works the same...
I have 5 different ones...(Motorola, Chinese, Samsung,..)
Cables and the Chargers themselves...so they all work fine for me.
I charge my phone at night so I don't notice if one charges slower or faster than the other.
But yea use it.

So my Verizon gnex won't charge past 59%, is that leading to the charging port going out or the battery going whack. Thanks in advance for any input.

If battery is over a year old, could be, especially if doing full charges more than once a day. There is a limit to how many full charging cycles the battery can take.
That was my first thought, but its the stock battery that was replaced by an extended battery within weeks after purchasing the phone around launch time

So does this happen with both batteries?
Hey all anybody know if the battery in the GN2 has a memory? i.e. If your charge the battery at 50 percent will that screw up the battery?
Sent from my GN2
maybe if you do that ALL the time.......i could not tell you if it has memory. but i cycle my battery from full to dead at least twice a week.
No it does not have memory and you dont have to drain, etc.

Well it was included in the at&t tutorial (dont ask my I actually went through it) to dispense your battery from full to nearly empty and charge to full again for the first time. But I dont know how nuch creadence im gonna give an at&t tutorial...

I think the first time is so and read can build its battery stats. But after that they say it's actually better to keep battery between 20% and 80% for longer battery life/How many charges it will take.
But I dont think any of us will have the phone long enough for that to matter.
Sent from my SAMSUNG-SGH-I317 using xda premium
I agree, plusbit takes too long to drain the battery.
Sent from my SAMSUNG-SGH-I317 using Tapatalk 2
No, you won't mess up your battery by charging it when it is at 50%.
A full charge cycle is considered going from 0% to 100%, therefore going from 50% to 100% would be half of a cycle. With lithium ion batteries, typically the more cycles that have accumulated the more wear you will see on the battery (it won't hold as much of a charge).
Keep in mind that batteries will deteriorate over time regardless since they are a consumable item, that's just how it works. I wouldn't worry about it too much.
That is strictly to get a more accurate % reading. If it doesn't know where 0% and 100% are it cant calculate in the middle correctly. It's actually not good to spend too much time near either end of the spectrum.

Maybe this question has been asked many time. But I still didn't found the right answer.
My question is really simple.
With current Galaxy Note 2 batteries technology. Which one the best way to Charge it?
A. charge whatever we want
B. charge when batteries below 20%
C. charge whatever we want without waiting until it full charge
D. charge whatever we want and pull off without waiting batteries completed (full charged)
E. charge when batteries below 20% and never pull of before it full charge
F. do whatever we want and we need. Batteries on Galaxy Note 2 is clever that we think
Sent from my GT-N7100 using xda premium
The answer is letter A.
We predict what we want with the battery not the other way around.
Charge it when you want to.
And plug off without waiting batteries fully charged?
Sent from my GT-N7100 using xda premium
best ans probably be A.
lithium ion battery life will getting poor as the number of cycle it charge-discharge no matter you charge at what percentage.
