Battery discharging while charger is connected !

Hello,
My battery is not charging while the charger is connected !!!
the phone detect the charger but the battery won't charge :s
any idea ?
thank you

Try any other chargers?
If yes, and still doesn't work then I'm going with faulty charger port. Just got done setting up a refurb from VZW b/c my g/f's gnex had this issue.
The only other thing I can say to try is bending the tab/metal plate in the middle of the charging port up towards the glass a bit to center it more. May work.

i've tried 3 differents chargers and usb cables.it shows "charging" on lockscreen but the battery drains !
i'll try to bend the metal plate to center it more.hope it will work
thank you got556

Are you using a wall charger or USB port? And if your using a wall charger have you tried changing the part that gos to the outlet, not just the cord itself?

yes i did change it and i have used 4 diferents chargers

i can transfer data when i plug it to the computer, but it does not charge :s weird !!!

I had this problem. The charging port (the thing in the middle of the port) on the phone was bent. Took a safety pin and moved it a bit.
This is the only thing that worked. Used different chargers and battery, nothing helped but this.

Can you get any kind of charge? I noticed last night that after I was at 100 percent for a while the phone shut off charging...is.that the issue, or no charge at all. If it's the first, the kernel may be shutting it down

This is a known Samsung hardware problem with GNex. The USB port's contact (in the center) is made from cheap, thin metal -- unpleasantly reminiscent of the Galaxy S cheap, thin metal GPS antenna; a total fail. It's really criminal that Samsung releases product like this, and moreover that they don't halt production and engineer the problem out before putting more lemons out there.
The recommended solution -- bending the contact into alignment -- worked for me for about 5 seconds. Repeat 5 times, and then the phone simply wouldn't start up.
Your best solutions:
1. If it's under warranty, send it in for a fix
2. If it's not, search this forum for instructions on buying (ebay?) and replacing the USB port.
In either case, I'd worry about the problem re-occurring. I bought the very overpriced desk dock so that I can charge using the pogo pins. However, in my car I still need to use the USB cable ... very carefully.
I wouldn't ordinarily get phone insurance, but in this case I'm considering it. Not sure if it would be a covered incident. Does anyone know of a well-priced third-party insurance company that actually provides the coverage that one expects?

Hi there.
Has anyone managed to fix this issue?
My phone has the same problem. When I try to charge it, battery icon changes to charging animation, but battery percentage will not go up. In settings, status of battery is "discharging". Also, battery settings page does not show any application using battery other than "Android OS" and "Screen" which i find strange - usually at least 10 apps are shown on this page.
Have tried different wall chargers and USB cables, have tried getting the pin in the micro-USB port to the middle. still no help.
On the latest version of JBSourcery ROM, if that helps.
Thanks.

battery calibration?
this may be the case if you recently flashed a new ROM and your battery is not properly calibrated yet. you may try to let the battery completely discharge and charge again (of course, this only works, if it is indeed not a hardware issue also, use only wall chargers)... repeat that a few times and your battery should be calibrated again... had this problem a few times after flashing a new ROM, but that fixed it.

Phone wont charge

Hi there.
Out of the blue, my phone wont charge anymore. The only thing that happenes when i put the charger in is a red light when the screen is off. No charge. Anyone have an idea?

Red Light means charging. ..what makes you say. .not charging? ... wait for some time
scribbled from my note 2 (N7100)

Hehe, maybe i explained a little short. Was just a little stressed out.
The charging light is on, but in the statusbar it does not charge. In battery app it says charging, but the phone still discharges.
When i was driving today the phone started charging after being plugged in after 20 minutes.
The water damage indicator is untouched. I flashed a diffrrent kernel and wiped all but system. Still same problem

Are you using the charger and cable that come with the box?
Different USB cables deliver different amps to the phone.
So if you're using a cheap one, it will suffer.

Never ever try to charge a phone with car chargers.

Sent from my GT-N7100 using xda app-developers app

Cars don't have proper power management system due to which it sends extra charge to the phone and damages the battery.

standard USB is 500 mAh. This means that is will charge the phone from 0 to 100% in aprox 6 hours.
USB 3.0 delivers around 900 mAh if I'm not mistaken. With a proper Kernel you can even raise the current in your SGN2 to 1000 or even 1200 mAh. This might impact your computer motherboard in the long run though.

Most modern phones have built in protection from damaging voltage so I can't see that happening.

I guess you should show a credible source for this information.
Since I've Samsung original car charger kit and it works very good since almost 2 years from now. Why should Samsung by it's own produces a car charger if it's harmful for devices they sell?
Several times I've travelled more than 900 km with my car and Samsung car charger online with GPS. Everything was perfect at all. Please don't spread misinformation if you can't reference it.
Thanks,

Phone has inbuilt charging mechanism, that's what protects the battery. You just need to supply it with 5v dc. I have a 12v to usb 5vdc 2A plug in my car. Unless there is seriously something wrong with your car (or the 12v to 5v converter), it will charge fine without damage to the phone.
Original Factory charger is 5vdc at 2 amps. Most chargers will only deliver 500mA (or 700mA) which will take forever to charge the phone.

if you use a correct type of charger, good quality ones it should be fine for 2-3 years and who keeps a phone for 2 years .But imao it's still not recommended.

Extreme Charging time on wall charger - only 40% in 7 hours

Thanks for taking the time...
My Note 8 3g is showing a strange behaviour as of late.
I leave it plugged in the original wallcharger from Samsung, switched on/ 3G active.
Plugging in at roughly 10% that would give me 50-60% in the morning after 7-8 hours.
Battery & Task manager don't show any permanent CPU hogs or wake locks.
Device is loaded with a couple of generic apps but not rooted...
With a 4600mAh battery and a the 2000mAh Samsung charger charging at 0.5C the tablet should be finished after roughly 3 hours.
My Note 8 is taking twice the time for half the charge?!
Before giving it a hard reset I would like to know, if someone has an idea / solution.
Thanks again for Your time,
Yoko

That is a worry. I get full charge after about 3 hours on my samsung charger, and about 10% charge per hour on my blackberry charger at work. Mine is the wifi only model though, i dont know how much juice the 3g and what ever other connections you have running will use and if that would make up much difference. Sounds like a significant amount slower though. Do you have access to another 2A charger to see if its a problem with the samsung charger rather than the tablet?

In my case was the faulty charger cable, I was getting nuts searching for help when someone (don't remember which tread was) said about that. There's a free app on playstore that shows you how much current are receiving your device. With that app I realized that it was the cable, not the charger or software related.
Hope that helps.

I would try, in order:
1. Check your battery stats to make sure nothing weird is chewing up the battery (should be screen, Android OS and possibly Google Services as the top culprits...if there is any *app* above those and you're not really using the app, uninstall it)
2. Bypass a surge protector (if there is one) and plug directly into the wall.
3. Try a different cable
4. Try a different charger
5. Try the charger and cable on a different device that uses 2.1a if possible
If there are no rogue apps, nothing changes and the charger seems to function properly, then you are probably looking at a hardware problem with the device. I would guess a factory reset wouldn't accomplish anything.

also if you are looking for a diff charger make sure the amps are the same. i believe its a 2a charge on this tab. if not then charging will take longer.

Thanks to all Your kind replies!
Sorry for staying quiet for a couple of days, it's been a very busy week for me.
My problem appears to be solved - it has indeed been the USB cord!
Seriously....who would have thought.
I use the exact same cable to charge my HTC One S without an issue.
Thanks again to all of You! :good:

I faced the same Issue. Just let the battery Drop to %0 and Turned off then let the device pwged in overnight. For me that fix it without using any apps
NB. I know letting Li-ion battery drop to %0 is bad!

anyone have a slow charging ?

im running ARHD 12.0 [Android 5.1] and facing 340ma charging, around 3-4 hr until full
anyone have the same problem ?
before i use this rom (running stock rom) i also have this problem.

I feel like it takes the phone a little to "set up." When I first got the phone it took forever to charge, now it does it fine within 2-3 hours. I plug it in and I see it charges decently fast. When I first got the phone it was really bad at charging though, I really was about to send it back.

Make sure you use a genuine charger. htc or samsung chargers seem to work fine.
An under powered charger will cause the phone to whinge incessantly about low charging power, refuse to swutch off the screen and waste power like its going out of fashion.
Htc logic.. Something not to be desired..
Sent from a stolen (and crap) HTC M9

Old thread I know but most relevant I could quickly find.
Using standard charger included with M9 I could charge from 0 to full in about an hour and a half to 2 hours maximum. Lately, it now is taking 9 to 13 hours with the same charger and cable. Have swapped out cable, no improvement.
On stock, no root, TMO, firmware 2.11.531.19. Charging with unit off, in recovery or bootloader makes no difference.
Any ideas?

Turn the device off and charge it. If it charges in the correct amount of time then you can assume you charger is good but the phone is demanding too much power.

I had problems with charging recently. Very obvious fluctuations in charging and not charging to 100%. The problem was lint in the micro USB. Search YouTube videos on how to safely clean them. It has to be worth trying.

Depends, I've had bum adapters before. Had the same issue with my old Note 3 using it's included adapter. I switched to a different one I had (an LG one) and it charged fine afterwards.

My issues were solved by the marshmallow update.

Battery taking too long to charge!

Hello,
I have been using this phone for a long time now, however it takes it an hour to charge from 0 to 10%
Really annoying. Does anyone know a fix? I bought this phone from eBay second hand, so not sure what to do.

I had the same problem and testet to charge with an other 2 ampere charger, now it charges from 0 to 100% in less than 3 hours.
With the standard charging adapter it took 9h.

i have the same problem.. i buy it from new but now it charges very slow about 9 hour with the original charger .. does anyone know how to fix it.?

You can buy a new charger. In my case the original one is working ok, but I wanted to get a spare one I could keep at work. I got one off Amazon (5v 2amp) and it works like a charm.

It can also be the micro-usb cable you are using. A lot of cheap ones can't take over 1A, some can't even do more than 0.5A.
0-10% should take no time at all. Try using the 2A elephone charger and a good quality cable that works on a different device.
