I've had my N2 for a few weeks now. Suddenly, it has taken much, much longer to charge the phone. I calibrated the battery, drained it to 0 and plugged it in. 3 hours later it's still at 50% (and the phone is charging while off. Any suggestions?
Are you using the stock wall charger and cable that came in the box?
The reason the battery is taking so long to charge is because you ran it down to 0. If you want your batter to last longer it's best to use the 80 / 20. What I'm saying is use the phone down to 20% and recharge back to 100%.

May be a faulty battery. Contact Samsung (I'm assuming that by n2 you mean note 2) and they'll probably send you a new battery.

I only had one issue, yesterday, and it was that my phone showed 25 percent charge on stock white Samsung charger/cable and I knew it had been on the charger longer than that. I rebooted and it showed 74%. Not sure what the hell this was about.
Old rules by what standard? Anytime using lithium type of battry is best not to run it down to 0%. I guess you don't have much experence with them besides your phone. I use them everday for my hobby. Sure you can run them down to 0% if you like replacing them quicker.

Huh? Its a lithium battery...those old rules dont apply. A little quick google on lithium batteries will explain this.
More than likely slow charges are due to a slow charge plug/cable...many prior posts on the charger.

Old rules were for NiCad tyoe batteries, where you did want to run them down to 100% and had to deal with other issues. If you do end up doing that Google search you will find the advice given is pretty accurate. Staying out of the high and low ends for long periods will give you many more cycles.

Buddy i am having the same problem ... did you find any sloutions
i went to service centre those assh**** have no idea and said that note 2 is a bigger phone so it will take 6 hrs to fully charge.
pl help me out
I know this would be obvious, but I figured I will ask anyway. Are you still running the stock kernel, or are you possibly running one without the capability to accept the 2.1A charging?

How can I check this??
Full charge of my Note 2 is at least 10 hours, it's to much
I have 4.1.1 original firmware
I have a telus note 2, I am running stock software, rooted, I drain battery down to 10% and takes abour 2.5-3 hours to fully charge with stock cable and charger. I have noiced on a custom room it always taking longer to charge. I always charge with phone off.in doing this , I usually can get longer life out of the battery as well.

You would know if you were running a different kernel. You would have had to install it yourself. If you are All stock (ROM, AC adapter, cable) then you have something defective.
Here is my screenon time with everything running all the time on cleanROM with 6400 mah battery.
-- Note II, TapaTalk II--
Batteries will last thousands of cycles charging to 100% from 50, but maybe 300 cycles charging from 0 to 100. Don't run your battery down so much. Charge it when you're not using it.
Note2 battery drain problem
I too facing battery drain problem in my samsung galaxy note2 from last 1 week after installing lattest software update.
Previously my note2 was charged quickly in within 2 hours. After software upgrade, which came as push message, my battery takes almost 5-6 hours to charge from wall plugin source.
Can any body help me in restoring previous version of software??
Hi Guys,
I have this peculiar problem with galaxy grand. Just bought a new handset and first two days the battery lasted for entire day.
And then it's like discharging in about 4-5 hrs only. I turn off 3g when not required.
The biggest problem is charging the phone. The bundled charger is 1A charger. Logically charging a 2100mah battery should take 2hrs but this one takes 4-5hrs. I ordered a 2A charger from ebay but when i plug it in, battery spy program displays alert in red saying "battery is high" not sure what it means, but I believe it's not able to handle the increased current.
My friend who uses samsung note uses a blackberry charger and charges it in 2hrs flat. Then why is galaxy grand taking a hell of time?
Thanks for the help in advance

Underclocking makes phone unresponsive.Powersaving mode is enough For deepsleep when phone not in use.. To monitor this,, download cpu spy from plays tore.. Use greenify app to freeze apps automatically when not in use... Change usb cable and try again.. The usb cable bundled with phone have too many complaints...

Because of phone improper settings. These can happen. Pls don't use task manager. It will eat more battery. Android already have inbuilt task killer to kill applications. If you have few bucks try to buy auto killer memory optimizer it tweaks android internal setting's and make your phone lag free.. Most of the time I playing HD games while charging.. My phone temp max goes upto 40°C.

Hello, I read a youtube review that the charging for this device is 2A. She mentioned that it will take an entire night to charge the device. Moreover, while using the device during charging, it is possible that usage is faster than charging and the device runs out of power. Is this really true? Is there any better charger to charge the device quickly?
I have a PM-600 in the USA and mine charges within 3-4 hours and NEVER does it charge slower than drain! I've owned mine since October and have at least 50 downloaded apps, watch vids and use A LOT of Email (3 accounts) and social networking (5 accounts and apps syncing)! The reviewer Was probably using a defective unit or has a bad app!

I had the same concerns about charging when I first got this tablet. Over several nights and days I could not get the tablet to charge fully.
I googled a bit and someone online suggested unplugging the usb cable from the wall transformer and reconnecting firmly. While a simple fix, this worked completely. Seems to be a common problem across Samsung devices.
With the stock charger it takes mine at least 6 hours to charge. I havent tried with my other 2.1 amp chargers...

I found the problem. Fixed it with the original cord only, no extension cables.
(and, I mistakenly had bought the 2012 version, but I just returned it)
I have bought a brand new p-601, since the first installation it takes more than 6 hours in battery charging.
Is it normal or there is something wrong with the battery/tablet.
Is it possible reset the binary counter to 0, cause I have rooted it twice?
Best Regards

Yes its normal, all Exynos Note 10.1 2014 take a long time to charge, My P600 takes 5 hours however others have said it takes them 6-8hours to fully charge.
Same here
Think it's because of USB 2.0
Note 3 with USB 3.0 in roughly 2 hours
Someone could calculate the theoretical time by comparing how much power USB 2.0 can put through vs USB 3.0. Should be roughly 2 times more.
So maybe there will come a Note 10.1 Pro with USB 3.0 and NFC

It's not USB 3.0. Only the Tab/Pro 12.2's have USB 3.0 anyway. Here's how Samsung implements USB 3.0; at least on the N3.
The Galaxy Note 3 ships with USB 3.0, unfortunately at least in its current state it doesn't seem to get any benefit from the interface. Although the internal eMMC is capable of being read from at ~100MB/s, sustained transfers from the device over adb averaged around 30MB/s regardless of whether or not I connected the Note 3 to a USB 2.0 or 3.0 host.
Update: USB 3.0 does work on the Note 3, but only when connected to a Windows PC with USB 3.0. Doing so brings up a new option in the "USB Computer Connection" picker with USB 3.0 as an option. Ticking this alerts you that using USB 3.0 might interfere with calls and data, but then switches over. Connection transfer speed is indeed faster in this mode as well, like you'd expect. It only appears on Windows as well, my earlier attempts were on OS X where this popup option never appears.
Charging is an interesting story on the Note 3, but primarily because of what doesn’t change. The Note 3 continues to use Samsung’s tablet charging specification and charger, which has 2 amps of maximum output. The Note 3 draws 2 amps over a considerable amount of the charging curve, like other Samsung devices (in the linear part of the charge curve). USB 3.0 doesn’t change things up here quite yet with the new supported charge voltages that are coming eventually with the power delivery specification.

The p600 has a battery capacity that is 2.56 times bigger than the note 3 (3,200 vs. 8,220mAh) so its not a fair comparison.
.
My P605 My P600 takes 4 hours.. don't know about the exynos version.
It is obviously slower than any tablet or phone. Very boring and annoying. The question is how to differentiate between motherboard failure and normal slow battery charging?
Try a different cable
I was having this problem a few days back but found a hint on one of the threads I found on the internet. I was using a USB extension cable with the Samsung charger. It was taking 1 hr just to charge 1%. Then I tried not using the extension cable. It's now charging 10-15% every hour. It's likely the calbe you're using is the problem. If it's not the original cable that came with the tablet, try that cable.
I just got mine for xxxmas, and it takes about 6 hours, give or take, to go from ≈5-10% to full charge, maybe less when I don't use it; and I guess I get about the same life most have mentioned (is there a way to track charge/discharge times?).
That said, I just plugged in at 15%, and I just crossed 25% in about 20-25 minutes. I use the stock charger and cable plugged into an extension cord as thick as my arm... okay, my forefinger--hey, I like having a good extension cord that can carry the juice, the precious juice!

P605 here, and yes, it's normal, . It takes even longer if you're using it while charging. My philosophy is: "I sleep, he charges". Not perfect though, due to the amount of time I sleep, not much.
So my P600 Note 10.1 normally takes 5 hours to charge from 5% to 100% and the last 20% usually trickles and takes 2 hours. I remember someone on xda mentioning to unplug and then plug back when it hits 80%, so that's what I did yesterday and it took a total of 4hrs10mins from 5% to 100%. No idea how it made it charge faster but hey it worked.
P.s I use stock cable and plug.

Mine Note SM-P605 takes 5 Hours to charge and doesnt matter if have it turning off charging. Shouldnt it suppose to be around 3 hours charging time with qualcomms quickcharge 2.0?
0-100% 5-6H
10-100% 5H
How do peoples manage to get around 3H charing time with LTE version?
Im using battery monitor widget to monitor the charging, from start its around 1600mah and from 80-90% it start to drop to 1500mah-1000mah. From 90-100% it tickles down with 100mah for each 1% charge.
Is this normal? Im using Samsungs charger that comes with the box with EU adapter plug, since its HK version I got and if it does matter.
@dt33 i guess the EU adapter plug is the cause of slow charging. P605 should not be taking 5hours.

Id doubt that EU adapter is causing it and also tried with 3 different adapter. Since they just make HK 3 stick plug to EU 2 plug and doesnt convert electricity.
If any have SM-P605 version and can confirm with battery monitor widget.With history stats, how much mA does it charge bewteen 0-100% and is it same as mine does?
With sceen of:
0-80% - 1600-1700mA
80-90% - 1500-1000mA
90-100% - 900-100mA for each 1% it reduce with 100mA.
Does Qualcomm tickels down charging from 80-100% as Exynos version does?
It isn't the charger or the cable, it's something to do with the battery. I've had two different units in the past week or so that have taken over 7 hours and sometimes the charging stops before it is full and the discharge varies so much from 3 hours to 10 hours with the same things open and this happens on different chargers. Samsung agreed that both units were faulty, so enough is enough, I'm going to try something else.
After reading here and elsewhere about the GN 2014 charging time, I checked mine this morning. I wanted to do that before my 15 day return is up at Bestbuy. Yesterday, I ran the GN 2014 until it came with a screen and said to connect to charger. I think it was about 3% left.. This morning I put it on the charger at 7am.. at about 11, it was almost full, I unplugged it, and then plugged it back up again, and at 12 noon it reported 100%..
I have read that at about 80% on charging, it is real slow, and to un plug and re plug at that time helps..Anyway, 5 hours to 100% is normal, so I am okay.

Thanks for u offering, but it doesnt matter now and Im tired of Samsung. Too many buggs and none fixes and theirs customers support is none existens.
Now I also got black screen, waking it up from sleep, touch stopped responding or superlag (whatever its), cant swipe between home screens bla bla and couldnt either click on oki to reboot the device. A long press on power button for reboot is only choice.
Also suddenly battery drain from 100% - 97% just in 3 min for scrolling around home screen, appdrawer, open apps.
This tab just have too many issues and not worth mine time or buy.
Today at work, mine friend told me that his Note 8 LTE that he bought for 2 months ago, have also screen shaking problem as its with Note 2014.WTF is this?
Waiting for 4.4 and see if it resolves any of the problems. Or else, I just sell this **** and forget about Samsung.
Hey guys, i bought a galaxy tab s 10.5 about 2 months ago.
I had no issues with the tablet and i love it so much..
I just see that it takes some time to full charge it.. [It takes about 4 straight hours to full charge the tablet from 0 to 100%]
I just want to know that is too much time to full charge the galaxy tab s 10.5?
NB: I'm using the travel charge that was provided with tab from samsung
It charges with 1.800mA. Results in approximately 4hours. Max according to specs of MHL3 connecter would be 2A, so pretty close.
