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?

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.

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,
I'm having serious battery issues with my Galaxy Note 2. From the past week I've been trying to fully charge it to 100% but it just isn't happening. I've put my phone in charging for nearly 9 hours and it went from 0 to 56% only. This has been happening for the past week. Even when my phone is plugged in to the charger the battery is still draining fast when I'm using it. This has not happened before and i don't think that my battery has malfunctioned as my phone was perfect just a week ago and its not that old.
I'm on Carbon ROM v1.5 JB 4.2.2
Is there a way I can fix this? Thanks in advance!

Do you have a 5 pin cable? The black one short one? Well that with stock charger is super awesome.

I've been using a Galaxy Note II since early February, and battery power has been absolutely amazing. However, the past several days, I've been experiencing extreme battery drainage. I didn't notice until this morning how severe it really was. I woke up for school at 7:15a.m. and it was 100% charged, but by the time I got in class at 8:15, it was already at 50%. Yes, I was using my phone on the way to school, but I only used Twitter for maybe twenty minutes, then turned off the screen. I don't have any heavy apps downloaded, and from what I can see, there are no rouge apps either. While I was charging when I got home (the battery was at 23% after desperately trying to save it all day) I noticed that the battery was actually draining instead of charging.
I've rebooted and tried using my sister's charger with no results. I set my screen brightness as low as possible, turned on power saving mode, and made sure that it says I'm charging under AC instead of USB. While charging my phone, my battery level at the beginning of this post was 68% and is now 63%.
What can possibly be wrong with my phone so out of the blue? Is it just a problem with the battery, or is there something I can do or at least try? Thank you for the feedback!
edit:
my phone is not rooted
Try to see the battery usage in the settings maybe some app is causing that, also make sure your phone is going into deep sleep. Thats all I can say, I have to admit is draining very fast

Hello,
I bought a gently used N900T a few days ago. The device is awesome and works perfectly, except for one thing. Charging the phone with the Samsung charging cable+ac adapter takes longer than forever. It charges at a rate of approximately 8-9% per hour.
A few notes:
Device on, device off, it doesn't matter. It charges at the same slow rate.
The battery itself, once it charges, holds that charge very well.
The slow charging happened both when I was on the stock rom and on my current Slim Rom.
I have ordered a new charger and a new battery. If the slow charging persists with these new accessories, am I doomed? Is the slow charging a known issue for the Note 3? Besides the new equipment, does anyone have any advice on how to solve this?
Thanks so much!

I am using a genuine Samsung Note 3 charger. The replacement coming is another genuine Samsung Note 3 charger. I'm sincerely hoping the one I have now has a cable problem or something. I really, really like the phone but I'm wondering if anyone else has seen a similar story or knows of a possible solution in the case that the new charger+battery do not work.

Well I have to be honest from dead it takes about 2.5hrs to get back to 100. On stock.using the wall charger with 2amps. When he gets his new charger he should be good or a good kernel swap. Either way it should come back to normal

I got a new charger and it's still charging at the same slow pace. What could possibly be wrong with my phone? The battery holds a charge, the phone works near flawlessly. I'm dumbfounded.

You gonna have to do testing or replace phone. Me I would change kernel just cause it takes 2 seconds. Let it ride a day if no change then a factory refresh. You have checked that no app is killing phone as fast as it charges right?
TWEAKED N3
Edit. I was just on his thread and a few guys having issues with either bad batter. UV/ oc .try a different ROM and kernel. Fresh install meaning Odin back to stock and start all over. Sorry good luck
As weird as this sounds, I tried the charger in a different outlet in my home and it works a lot better. The battery charges quite fast from any level to about 96%, then starts crawling again to 97, 98 and stops at 98. I opened battery calibration, which shows the battery at 96% and 4337mv, which is the same mv level as 100% normally if memory serves me correctly. So I'm thinking the battery is "full", but for some reason won't go to 100% without a fight. Perhaps if I clear my cache+dalvik cache? Any other suggestions?

What was wrong with mine it was the charger. The usb wasn't connected all the way in the AC therefore was only charging like it would through computer as soon as I fixed it with a blow of air and a gentle push it right away started charging AC phone charged in 2 hours
I could be wrong but I noticed my charging is slower when I stick my charger into a surge protector power bar as opposed to a standard wall outlet.
Mine was the charging cable I used a regular USB charger cable and it charge fast

Samsung Galaxy tab 3 7" SM-T210R. Recently my tablet has been having problems charging. Like when I plug it it it takes forever to charge. Before I could use it and it would also charge. Now when I charge it and use it, it stays at the percentage it was at when it began charging. Sometimes when I unplug it, it'll be lower than before. When I put it on charge over night (6hours) it'll get to 100%. I'm still using the original charger that came with the tablet. Any help would be thanked.

Me too
Exactly have the same problem, I'd like to ask first, are you rooted? What rom are you using? Because that could be the issue, I'm rooted and I'm using nolekat rom. It takes me 10 hrs or more to fully charge and it drains half the time fast. The percentage on the battery jumps higher then goes lower and it decreases while I'm charging and using it and I'm not doing anything heavy. I already tried using the battery calibration app which most people recommend to troubleshoot first, it didn't work for me. I suggest that you try calibrating first and if it doesn't work, reflash your current rom if you're rooted, if you aren't, it could be your charger and I also know my charger isn't faulty. Last thing I'll suggest is try manually removing your battery for 5mins then put it back in. I haven't tried that yet, I need the tools still. Hope this helps and let me know what you've done.

thanks for the advice. I recently removed the rom i was running. it helped Thank you very much. I also removed my battery by opening my device with the back end of a knife it you do it gently it really doesnt scratch your device plus if you have a case/skin you can't see the part where you wedge the knife. Thank you !
