[Q] Battery Taking Too Long to Charge

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??

New issue..

Okay. Got a new problem. I have my phone plugged into charger. It says it's charging. Shows the lightning bolt thing on the battery too. But while I'm using the phone, even while it's plugged in, the battery % goes down, instead of up. But if I just leave it & not use it while it's charging, then the % will go up.. Just extremely slow. I have a new battery & a new charger. I even tried my old charger & it still does the same thing. So why would the battery go down, eventho it's plugged in? I don't understand. Please help

It may depend on what your doing with the phone. If your running a system heavy app like the browser, camera, Facebook or a game that has a lot graphics and the processor is cranking, the charge rate may not be sufficient to replenish the battery.
Especially if the battery is way down to 10% or less.
My wife does the same with angry birds. You have to let the battery catch a breath and charge up.

If you are using your phone a lot while it's charging, especially if the screen is brightest, battery sucking apps, cruising the net, a lot of texting, then chances are your battery is draining faster than its able to charge. Try this. Run your battery all the way down till it dies. Then let it charge completely full, then run a battery calibration(download this from app store before you let phone die). It will calibrate it when it's at 100%. That should help some. But if you use it a lot while charging, it very well may discharge faster than charge. But try the above, it should help. Good luck

I have never had this issue with the stock charger for this device, even when using high intensity apps. It will happen if you are using a 3rd party charger, even of it says it is a full 1 amp output, it cannot keep up while using the device. Make sure you are using the stock charging block. If you are, try replacing it with a new OEM charging block.

What brand of new battery and where did you purchase it?
Sent from my SPH-D710 using Xparent Cyan Tapatalk 2

It's a Samsung battery. Got it from sprint.
It was fine, until about the past few weeks. That's when it started doing it. & the battery will never be below 10% when I'm using it. It could be at 70% & will just start going down while plugged in. It can be at 100% and it will be plugged in. I do one thing on it & it goes down to like 70% suddenly. Then gradually go down more.
I will try calibrating it
Sent from my SPH-D710 using xda app-developers app

Try taking the battery out and leaving it out for 10 minutes. If that doesn't help then I suggest taking the phone and battery to Sprint and have them check both the phone and battery. It could very well be a defective battery. Are you running a stock rom?

[Q] battery drain while charging

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

Phone slow charge?

I bought my S3 on july and no flaw what so ever, I used to play PPSSPP, I would say its a battery draining app cuz I needed the phone at full power to play, I could play while changing and the battery actually charged, but now. Even by using Mango (which doesn't need much resources) and power saving turned on, plugged in and the phone's charge drops instead of rising. Any idea as to why?

Im rooted and on 4.3 and I can go from 100% to 30% in a little over 4 hours. The only way I can get my phone to charge now is through a wall charger. Even then its taking forever. Not like it was before when I was on 4.2

my phone only accepts OEM Samsung chargers (cant use any other charge cable or box), and a really good wall plug in order to charge

That happens to me sometimes too but usually it charges normally after a reboot.

[Q] N900T Extremely Slow to Charge- Tips?

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
