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.
-- 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??
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?

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.

Here are some fast charging tips and tricks that actually work :
1- Turn on your airplane mode.
2- If you are waiting for any important calls or messages then ignore step one and simply turn off any unused feature like wifi and bluetooth.
3-Atleast once in a month charge your mobile from 20% to 100% this enchances battery life.
4- Atleast once in a week restart your mobile or switchoff the phone for 5 mins remove battery and reinstall and reboot.
5-The most effective is that buy a charger of a mobile like note 3 coz it charges faster than normal grand 2 charger(use at your own risk)
6- If you feel your mobile is getting hotter while charging turn off power saving mode if issue still remains turn off the phone.
Why use another charger? Using another charger than that specially designed for the phone may apply different voltage/current intensity to the battery, and thus affecting its efficiency...
You shouldn't be using another battery, every phone has its own battery charger, it's not a battery cell!!
I'm using a note 3 charger for my grand 2 for about 7 months and well it haven't affected my battery or phone and I bought it from a Samsung store and that person said it won't affect the battery but only charge it fast
"charge it fast" means going abnormal... Nothing's called charge fast and drain the same, if you charge your battery faster than it's intended to be, it'll cause trouble, most probably draining fast or the reactants of the battery wearing out fast, and 7 months are nothing lol!

Battery-gate has everyone paranoid.
This sounds like BS. When Samsung investigated 90+ cases of exploding batteries, it found that 26 reported cases were fraudulent scams - this was in the news today.
It sounds like the same ****.

This.
I would believe the below from the article before I'd believe Samsung's stupid enough to make the same or similar mistake twice. I was worried about QC on the replacements considering how fast they're racing down the production line. Mine's perfect BTW. Any articles about Samsung because of what's happened is guaranteed click-bait. A Note 2 overheating on a plane made front page news with whatever (still to be determined) happened to it being tied back to the Note7 issue.
"The issues being reported in South Korea are related to minor errors with the mass production of the new units."

Mine seems too also but I thought it was all in my head. It seems smoother and snappier for want of better words. My old phone would occasionally get choppy and stutter as if it was struggling with something in the background. The new one doesn't. It's on AT&T and the new phone's shipping s/w was the same as the old phone's updated s/w. Curious.
My s7 edge and note 7 (both exploding and non-exploding versions) have always had times where they charge slower than they discharge. (Waze + Pandora when it is super sunny, so 100% brightness. Even on QC2.0.)
The new note7 (and/or new firmware) pops up a warning to say as much. The S7E had an overheat warning that came up occasionally in similar conditions (even air-conditioned, DC summer is warm..)
I think the only difference is the notification that its happening, which is nicer than discovering after a drive that you have been losing power the whole time.
I'm experiencing the very slow charging issue. In fact when I was watching a movie while fast charging it was losing charge!?
Sent from my SM-N930V using Tapatalk
I have experimented the same thing, actually ending with less batt while using and charging with other devices, so, this happening with the note 7 indicates nothing wrong with the batt
Customers in South Korea who received a replacement device have reportedly complained the phone's battery is overheating and drains too quickly after use, according to a report by YTN, a TV network in the country.

Fast charging does not seem to want to work on my new one, with stock charger brick and cable. I am hoping I don't have to go BACK to TMo and get another new phone.
my replacement seems identical to my original, same charge speed, same discharge speed.
as for the people saying about watching movies and such and the battery ending up lower, that is normal, if you are running the screen and charging not only does the battery get warm, so does the CPU so the phone will start to throttle the charging. I've had phones in the past that refused to charge once the CPU got above a certain temperature. this is just people being paranoid or looking for a way to get money as mentioned above with the fake tales of exploding batteries.

Odd. I use my Note7 (pre and post replacement) with Android Auto via USB. Android Auto really puts a load on the phone. Even off the wimpy output from my car's USB port the phone never loses charge and frequently gains it. My previous Note5 was the opposite. It would stay even most of the time but would lose charge on occasion. The only difference between the two scenarios is I got a Orange-E 12" Type C USB cable to use with my Note7. So my experience is different than yours.
I suspect the screen is the big drain. 100% brightness is vicious. Isn't the screen off for android auto?
Things it's usually doing when it drains (starting from 70% or so) :
Overheating (direct sun, no ac pointed at dash or top/doors off)
BT music streaming + wear
GPS
100% brightness
QC2 (aukey car charger)
Even without overheating that combo usually only gains me about 5% over 30 minutes.
Unrelated, but without getting too far off topic is AA worth the jump? (~900USD if I want my steering wheel controls and stuff)

Yep. When in use and the display is on its black with the Android Auto logo. But the phone's still using all its radios and if navigating pushing data to an 8" display so the phone's definitely under load. I have a Samsung Fast Charge car adapter but the problem with Android Auto is it doesn't let you connect by BT so the car's USB power output is all you get. But as a comparison under the exact same conditions the Note7 definitely either drains less or gets more power than my previous Note5 and both phones are/were configured identically.

A black screen with amoled means the only pixels lighting up are the ones in use. The screen itself is a massive drain so the more pixels are lit up, the more the juice is drained from the battery. That's why AOD doesn't kill the battery fast.
Sent from my SM-G935T using Tapatalk
Ive used a USB multimeter on both my old and new note7.
No matter what, old or new note7, the charging rate gets cut exactly in half when charging with the screen on. This happens when using a quickcharger or a normal 2.4a 5v charger.
So if you want full speed charging the screen needs to be OFF.

I beg to differ, because they have that wireless backpac battery that is completely sealed from water for the Note 7. The purpose of the permanently installed battery is for the NSA to track people since the battery cannot be removed from the phone.
so I bit the bullet and purchased a new batt at the repeated recommendation of this board. I will find out more if that really was the issue over the next few days of use.
however... 1 issue still remains. it appears that the battery % lies while charging with the phone on... i can't honestly say this was an issue with lollipop as perhaps i just never noticed it... but i normally charge my phone in the AM (not overnight) so that once it's fully charged i can pull it off the charger. what i have noticed is (am on MM now) is that i get the popup that says batt is fully charged (lightning bolt not on the batt indicator) BUT.... if i power the phone down it shows the batt is only at 94-96%... so i leave it be and it takes a good 45-60 mins of further charging to achieve 100%...
what is that??? it seems like a complete software issue to me...
my thoughts are... perhaps it's only specific to samsung and may be related to the note 7 problems and maybe samsung made it to where the software prevents over charging? idk... anyone else notice this?
***note*** i do NOT use fast charging.

Sounds like your battery is draining pretty fast.. how long does it last at full charge?
I run mine permanently in Power Save mode and I can push a good 10 hour + on it with normal usage. Also why would you not use Fast Charge? Thats the best part about having this phone..
