Does it charge on the wall okay? I would try a different kernel out, see if that remedies it. If not, I would be suspicious of a damaged/faulty USB cable(they do/can go bad), or a faulty battery. Have you tried clearing your battery stats yet? I would do that, as well.

I'm guessing battery too, sprint should have a machine to check it by the way...

It's happened to me a few times. Sometimes the cable wiggles or something I guess.
I just unplug and replug and its fine.

I've had this happen consistently over the past few weeks, only with my car dock though. It charges fine both in my dock at work and on the standard charger at home. I'm using a Seidio dock, and I've done multiple things to find the issue. Both my wife and I have EVO 4g's with Seidio car docks. I swapped my dock for hers, no change. I swapped out the charging cable, no change. I used a different charger, no change. I tried my normal setup on my wife's phone, no change.
I don't know what else to do to figure the issue out. I have ordered a new charger that supplies 2.1A, as I've read that a low charger output could be the issue.
I am confused, as this combination has worked fine for about 8 months now. Why all of a sudden is it no longer charging properly? The battery could be the issue, as I know that the chemistry changes over time, but I'd like to know for certain before swapping out the battery.
I'd love to hear from others who are having the same issue.

Seidio Dock issue?
I've seen a few other posts with the same problem. Particularly this one: Post #1175
http://forum.xda-developers.com/showpost.php?p=16499063&postcount=1175
The one thing that is similar is that he is using the same car dock as I am, the Seidio dock.
I've been playing with this a bit, and have managed to isolate it to the Kernel. I flashed back to MikFroyo and the problem disappeared. It charged perfectly fine.
In Gingerbread (MikG 2.42), with both the stock Kernel and the Freedom Kernel, the phone won't charge properly in the dock. I've been keeping an eye on it with Battery Monitor Widget. Here are the results:

}
While I am driving, the kernel is showing a 100% full battery, however, it is discharging instead of going into the float mode. As soon as the phone is removed from the dock, it goes from 100% down to 80%. When I put it onto a desk charger, it charges fine with a normal float charge. If I remove the cord from the Seidio dock and plug it into the phone (with a mini -> micro USB adapter), it will charge normally and go into float mode.
Something was changed in the GB Kernel update that affected this behavior. Unfortunately, I'm not a programmer to get that deep to find out where the problem is.
Is there any help possible from anyone???

This always happens to me on AOSP roms. If you happen to be on an AOSP rom, just plug the charger back in then take it out.

I've tried that previously with no luck. I'm using a Sense ROM, currently MikG 2.42, but I had the same issue with the stock GB ROM.
Thanks for the suggestion.

[SOLVED] Good external battery charger?

I'm looking for an external battery charger since I bought a couple extra batteries for my phone.
anyone have experience with a certain charger? Obviously I don't want something that will damage my battery but nothing that will break the bank either.
Thanks.

Anything wrong with the charger that came with the phone??

I need a charger that I can put a battery on so that I can use my phone out of the house and a second battery can be charging at home..

Yeah, sorry I probably should have been more specific but I dont know the exact name for them. haha
It's like the dock "travel" charger for just the battery, not the battery connected to the phone.
I havent been able to find something decent (crappy charging, made in china).

Ok a little update for those interested.
I ended up buying some cheap (REALLY cheap) charger off ebay not expecting too much but just experimenting.
The charger itself looks something like this:
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",

"lightbox_toggle_sidebar": "Toggle sidebar"
}
The 2 metal prongs connect to + and -; the charger is able to read which is the + and which is the - no matter how you set the battery in there. The bottom part that pushes the battery toward the prong is extendable or you can flip it 180 if you have a really small battery.
-Flashing red and blue light means charging
-Dull red light while plugged in means fully charged
-Dull red light while not plugged in but with battery set up means the pins are set up correctly on the terminals
NOTE: do not take batter off/put battery on while the charger is plugged in. It can ruin the battery.
The exact one i bought:
http://www.ebay.com/itm/270908124203?ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1497.l2649
(no problems with the seller, they actually sent me a few free ones due to a misunderstanding)
Now for the review and my experience.
Pros:
-Fits any battery, interchangeability of pins (differentiating + and -) means you can fit any battery really
-Has a side USB port so you can charge a battery and plug in your USB cord to the phone and charge it at the same time
-Voltage input is 110-220V so (with an adapter) you can theoretically (will test this summer) plug this charge straight into an european plug or north american plug.
-No problems so far with over charging; Charger stops charging the battery when it is full
-Has a light to tell you when the battery is done charging and when you have the pins connected correctly to the battery
-Compact; Small and plug folds up into unit.
-Charges a fully dead battery quickly.
Cons:
-No instructions when I first received this product (i know what you're thinking, how hard could it be to just charge a battery but I was reluctant to rely on the self detecting terminal feature)
-While charging, the light on the unit (the one i posted/bough) flashes red and blue like cop lights and is very bright so it might be a problem if you are plugging it in overnight in a bedroom. Also this is a normal function of the charger but i thought it was malfunctioning so they sent a new unit but then figured out its normal.
-Looks cheap
-Dont know how long it will last for (really cheap so buying another one isnt a problem)
-Noticed that after i pull a battery off the charger and use it the phone states it is at 99% (undercharged) although if i try to bump charge a fully charged battery it wont charge more. This could be a problem with my battery/phone/etc.
-Nothing else really
So final verdict on this product:
Its a great, affordable charger; works great if you are traveling and need to charge an extra battery. Will fit the Incredible 2 extended batteries and technically virtually any battery. Its pretty easy to use once you know what the color lights mean and how to set a battery up.
If anyone has any questions or want more pictures of this product just reply in this thread. Hope this helped out anyone looking for a product like this.

i just wanted to jump on here and say rthank you for posting this. i just oredered one for myself. i droid incredible 2 usb port took a dump on me and now have no way to charge it now without taking it apart and replacing it. thanks again for this info. it will hold me over till i am ready to fix the usb port or get my upgrade. i will just the ftp app from the play store to transfer my files till then.

mine did the same thing just a few days ago only issue I"ve ever had with the phone...I actually ordered this same one off of amazon about 10 mins before I saw this, lol. Glad it works well

Phone won't turn on :(

I've been experiencing some problems with charging and I read in out of the threads that I could use a bit of electrical contact cleaner and it would work. And now my screen protector is ruined and my phone won't fully turn on. It boots up, vibrates then it turns off. What do I do I'm freaking out right now. I'm going to put it rice to see if that works at all Anybody know what I should do I'm really scared right now.

Exactly what did you use? Link to the product.

Yea a little more detail on what you used would be very helpful.

Jesus I feel like the biggest idiot of life. You guy don't realize how F*cking stupid I am. After being in a complete rush I used the wrong type of cleaner. So After I soaked it in rice and took it out I actually used a proper Electrical Contact cleaner and and now everything is fine. But I am now certain that the cable is done because it wasn't charging or showing that it was plugged in so I used my friend's Blackberry cable and everything is fine. I'm so relieved right now.

Lol glad to hear that its fixed.... we all make mistakes

Thanks, the only problem I'm still back to is that it won't charge, which is what was happening before. I am not sure whether it is the charger itself or the micro-usb charging port (Which I could replace). Phone thinks it's charging with the lightning bolt in the top right, but it won't charge...if I go to battery in the settings it says discharging but in the charts it that it was charging all this time.

I'm trying that right now. If it doesn't charge does that mean that the charging port is dead or could it mean that the battery is dead aswell?

Tbh I don't know but this is a educated guess.... seeing that it shows that its charging on the phone means that its receiving the charge. A good test would be to take out the battery and plug your phone into the charger. If it works that means that the port is OK and you'll need a new battery. If not then its the port. Hope this helps.

What do you mean by if it works, as in if the phone boots up and works normally when plugged in?

When you take out the battery and plug it in to the charger it should work normally as its getting power from the plug.

What on earth is this crap?

Well that's odd..... idk

Meh whatever, I smelled and it was just the smell of the wrong cleaner I used, luckily it was just on the plastic parts so I'm safe, I disassembled the rest and found the charging port. I'm ordering a new one for $10 shipped from NJ and not from HK so I should get it soon. Thanks for your help btw. I really appreciate it. :good:

Good luck bud

Update: I just replaced charging port literally just now and it still won't charge. It still says "Charging" but it's not charging. In the Settings it says discharging.
Could it be the battery? I'm thinking of buying a new one and seeing if that works.

Updated Update: The 6% that had remained on my battery before I took my phone apart to repair it is now gone leaving the battery with 0% charge. But, I believe I may have found the problem! If the phone is unplugged from my charger and I try to turn it on it won't turn on at all. But if I plug it into my charger it will boot up past vibrate to the Nexus logo (The X) and then it dies out. I think that the problem is in the charger that has a input voltage drop so it's not charging enough to keep it going. I'm going to use my friend's Samsung Charger (From his Galaxy S II) to see if that will solve the problem.

what in the blue hell is going on? (battery charge sucks)

so i tried charging my phone in different outlets, using my other family's charger, different cables, everything.
as of like 15 days ago or something, the charging is extremely slow (like it will take 8 hrs to COMPLETELY charge)
look at the graphs.
what in the world is going on here??? sometimes juiceplotter tells me that my wi-fi is on during the charging (which it shouldnt be since juice defender is supposed to turn it off when screen is off, but EVEN if it was on 100% of the time, the charging should NOT take that long)
but in most cases, the wifi is actually off so wtf is going on?

I got some retractable charger from radio shack and it charges my phone twice as fast

yeah but this problem persists no matter what charger i use...and this has only happened as of a week ago.
the only key point worth noting is that im on the leaked kelly bean LT7 ROM

It's not your charger that's fine but a better charger that put out more power than the stock charger.stock charger suck, I went to Wal-Mart and bought a charger that put out three times the stock battery output and it takes me less than a hour to fully charge it works my stock charger is not used at all. I had the same problem until I searched around. Hope that helps. It helped me and others you will be amazed at how fast it charge.

Yep. The stock charger sucks. I got one area radio shack and i can also charge mine from 0-100 in 1.5 hours.

I use my stock charger at night when I don't care how long it takes to charge (it takes a ridiculous ~8hrs to charge). When I need a quick boost I use my old HTC charger and HTC cable. I think the output amps is higher but it seriously only takes an hour to fully charge my S III.

SM-T320 slow charging

Hi guys, anybody has an idea why is my SM-T320 is changing that slow. It almost cannot reach 100% even if I keep it 13hrs or more on the charger. Reboot doesn't help, maybe if I switch it off is a little bit faster, but not so sure.
Thanks in advance.
Sent from my SM-T320 using Tapatalk

Yeah sometime it happens with this device my best advise is don't try force charging it (leaving it plugged in), it will only make it worse and damage / overheat the batt..
Do this instead leave it at the current charge and use the tablet until the battery is down to about 10-15% then reboot the tablet, see if the percent changes as this forces the tablet to re-evaluate the battery, then fully shut down press the power button down for 5 - 10 seconds and choose power off.
plug the tablet into the samsung charger (don't use unofficial chargers/ cables if possible), it should reach 100% now.
some other things I have tried that can help
I have a cable that monitors the amperes and sometimes I notice the tablet doesn't request enough feed from the charger (it starts trickling at like 100mA) usually when its almost nearly charged,
so sometimes if you force keep the screen on with moderate or full brightness, and power saver turned off while charging this causes the charger to send more current and you will notice it will say 100% a lot faster, so that is another thing you can try.
As a last resort you can re-seat the battery but I would only suggest that in extreme cases.

[email protected] , thanks. Last night exactly at midnight i put it on the charger, it was on 50% like. After 7 hours it was 95% . I rebooted it and after 3 minutes it was 100%.
Sent from my GT-I9505 using Tapatalk

I was having the same problem, changing the usb cable did the trick...

I tried with my i9505 charger which is the same but again the same issue. Actually for example when reaches 30% it stops you have to reboot the device to continue chargin. Sometimes but not very often it charges normally.
Sent from my SM-T320 using Tapatalk

Yeah it's very picky sometimes I wonder if it's temperature related, mine was never as bad as yours but I have seen it stop at around 95% a few times, I have an amper cable and it reads like 100mA - 50mA (in standby, 0mA - 10mA if wifi is off), sometimes unpluging the charger and re-pluging it in gets it going again.
You could try to fully shut the tablet down, and keep it off for 24hours - let everything kindof reset and discharge (like if it was exposed to ESD) , shame samsung didn't include a reset button since that would be like pulling the battery.

You might have the same battery problems many of us have, check the link in my signature on how to fix it.

I had that problem too.
Tried drain the battery end then it would sometimes charge to full but after 1 or 2 charging cycles the problem re-occured again.
Reseating the battery was the solution for me. After i have done that the problem never occured again. ( 8 months ago )

I believe it's somehow related with the smartcase. You guys have smartcases?

No, dont use any case.
I dont believe it is heat related. The onlu thing i did was disconnect the battery and reconnect. After i have done that it was like i had an new battery.
No problems with charging anymore and a little bit more stamina.
Dont know why, but many of us had this problem and this seems to fix that "bug".

I use an amp cable (shows the current flow), if the reading is less then 1880mA (at 50% or less) then I unplug the charger and cable use the tablet alittle more then re-plug it in - hasn't failed me yet

I think I found a solution :
Leave the device to complete discharge until it switch off by it self. Then put the charger but don't switch it on. Let it charges to 100%. I did that 3 times. Now I successfully charged it to 100% 2 times without switch it of.
The reason why I am looking for that kind of solution is because I have warranty, but Samsung will keep it for like 2-4 weeks.

Actually when you have disconnect and connect battery, the battery connector doesn't make good contact with pins of the black battery connector on main board.
The fix is very simple, push the clips of battery cable closer
