I've noticed that when I leave the phone plugged in overnight it sometimes just seems to stop charging at a random point somewhere throughout the night and I'll wake up with a phone that is only at 80%, 65%, etc.. battery. It isn't fully charging and then just being drained again either, it just randomly stops charging. It will recognize that a charger is plugged in and even says that it is charging but the percentage indicator in the Settings pulldown doesn't move. This doesn't happen every night and it has never happened when I charge the phone during the day. I assume it only happens at night because I'm not at my desk using it. I can also assume that the device isn't taking 8 hours to go from 35% battery to 75%, it doesn't charge that slowly. Any ideas?

I'll give it a shot. Thank you.
I tried it with a different cable last night and it did the same thing. Forgot to mention I'm charging it through my computer.

I would try the charging cable that came with it and if it still does the same thing I would say you have a problem with your phone.

Yeah, I have been using the cable that came with it. I've tried two different ones. I will try to see if it happens when charged through wall outlet.
Sorry for double post. Couldn't figure out how to attach image to an edit.
I looked at my battery settings and this is what I noticed. It looks like my phone is charging all the way up during the evening and then draining but the charging isn't kicking back or something. The huge gap in screen on time was when I was sleeping and there was no use of the device but battery is steadily draining.

As stated in previous post, I have not. That is the plan when I get home.
I have tried it through the wall charger for the past few nights and it charged just fine. I also tried it through the same cable that my N7 and Gnex were charged with and it still happened. I also tried various USB ports. Any ideas?

Is it possible the computer is sleeping and no longer powering the USB ports?
I had exactly the same problem for one night.
But it can't be a problem with my Notebook because
my Galaxy S charged just fine.
Probably due to power saving options on your computer, be they USB power saving settings or sleep related. If you want to charge faster you should definitely use the wall charger, USB charging is painfully slow for me... if i am using the device, load can exceed the incoming current and the phone will still discharge. Moral of the story > USB charging = useless.

It really isn't a matter of slow charging. I'm charging it overnight so the speed at which it charges doesn't matter to me. As long as it is charged when I wake up. I've been using the same computer to charge my phones/tablets/cameras for two years and I've never had a problem. I'm not even using the device though, it is at night when I'm sleeping.
I have the same problem all of a sudden. Happened twice in the past week, never happened for months before. I never charge from a computer, always with the provided adapter and cable from the wall. A few hours into the night, before the phone is at 100% (varies from 70-90%), it just stops charging. Battery graph looks very similar to the one in this thread already posted.
I wonder which device switches the current off, the phone, or the wall adapter. I would have guessed the phone, and if that is correct swapping the wall adapter won't do anything.
Or you can use Fast Charge from Google Play and flash Franco Kernel.
Then you'll be able to switch from USB Charge to AC Charge by charging with your computer.
However, the battery will heat and you may consume its life, so do not do that too often, only when necessary if you expect using your phone very long times as i do, i just change phone every 5 years or more, depending of my needs.
Also, i noticed than USB Charging slowing down the charge at around 80%, but still charging, i read with Battery Monitor Widget, and i seen it will gives minus ampere.
I almost forgot, you may also calibrate your battery, the first time, charge it to 100%, then remove the file "batterystats.bin" from /data/system or wipe it threw Recovery, that will ensure you to use your battery to 100% next time.
Mine seems to stop charging at 100% and go back down also. Mine usually is between 95-100% when I wake up though. Is that just how this phone works to protect the battery? I've never noticed this in any other phone I've had.
There seems to be a bug, where if i leave the phone connected overnight on the stock charger and wifi is off when i wake up the battery is at 80% or less. My theory is that as soon as it reaches 100% it stops charging, has anyone experienced this?

This is happening to me as well; I've come to believe it's a faulty charger, actually. Or a charger designed that way. But the charger's fault regardless.
First occasionally, but now for a few nights in a row, I've found a phone plugged in overnight to be at 80% battery in the morning. When I look at the battery graph, it appears to have charged rapidly to 100% (or close-to), then started slowly discharging. However, with the battery use screen open, I also noticed that the status was rapidly changing between "Charging (AC)" and "Not charging", spending most of the time in the not charging state, despite a constant plugged-in icon in the notification area. This behavior persists regardless of wifi state and through many reboots; BUT, it hasn't happened at all yet (with just limited testing) when plugging it in through the adapter for my last phone (an HTC), nor does it happen when charging via USB. I don't know if the LG charger could be designed that way, where it stops when it's full, or if it's just a faulty unit that needs replacing. I'm going to try it on the HTC wall unit overnight tonight to see what happens.

I'm actually having a similar problem... For me I noticed that the screen stays on while the battery is discharging while on AC charging mode so it may be a different issue. It doesn't always happen but when it does, I'll be sitting around 75% when I wake up in the morning.

Just checking in - a few days later, it hasn't happened yet using the HTC charger.

Turns out this is caused by using a USB extension cable... it would say the phone is charging on AC but there would not be enough current going through. When I plugged the the stock usb cable in to the charger directly, it charged fine.
I usually charge my phone using USB while in the office. At home, I'll use the supplied wall AC adapter.
I've noticed that even though I'm using the AC charger, the stock battery display will show Charging (USB), which is not the case. Power cycling the AC charger usually fixes it to show Charging (AC).
Have also noticed that in some instances when it's plugged into the AC charger, the charging status would switch between "charging" and "not charging". Very obvious in the notification battery icon, where I would see the lightning symbol appear and disappear, about every half second.
I think there's an issue with the AC charger, or maybe it's the charging circuit in the phone?
Anyone experienced something like this before?
Cheers

Sounds like a hardware issue. If you want to run the test yourself, you can try swapping the charger with another OEM Nexus 4 charger (don't try to get around this). But I'd contact Google about this if I were you.
Might be the stock charger if thats what your using i had the same prob and sometimes but battery would either stay on the same percent for a while or go down so chanhed the charger and its been working fine ever since i still use the stock box charger i just changed the cord

i had similar issue..when plugged it shows charging/discharging..if charging it will be slow as hell..swap cable all good..
throw away the original cable try a different one..
Thanks. Will give it a shot and see how it goes.
Do you guys think this is a charging issue? Temp is very high but still continues to charge at AC level. I have switched out my power bricks and cable but still have the same result.

It is due to temperature I believe. I have observed this behavior closely for a long time, so I'm almost certain this is the cause. I've seen it on the Galaxy Nexus and the Nexus 7. I can't tell you offhand the exact temperature they stop charging at, but I can tell you it's most likely between 50°-60° Celsius. You've got to let your devices cool off. It may be a pain, but it protects your hardware, so when it stops charging, your phone is saying "Hey partner, you think you could let me cool down for just a second? Is that too much for you or what? What's your problem, you dingdong?"..
... Or something like that. If that's not exactly what it says, it's very close.

Ah I see. Anyways, I have used my cousins nexus 4 and every time the temp goes over 38 degrees, the charge rate drops down to USB. Mainly why I asked haha. Yah its a pain from time to time LOl

Same here. Worked out for me it was a dodgy cable. Using the supplied cable through a laptop, I will also from time to time get the plugged/unplugged notification on the computer, which being audible made me realize how often it was happening.
The supplied charger brick now seems to work flawlessly with a different cable (ie, always says AC, no odd charging/not charging behaviour, etc).
Try that and see how you go.
I guess it's the cable. I've tried using a generic ebay cable and it appears to be working fine now.
What sort of mA values are you getting when using the stock AC charger?
Battery Monitor widget says that the phone's only getting around 500mA when I believe it should be getting more than that. I've enabled the USB fastcharge in the options. and have left everything at default. This is after waking up the phone from standby. Keeping the screen on drops the charge rate to 200mA thereabouts.
No music playing, 3G and connected to a wifi access point.
Does anyone else have any experience with Qi wireless charging receivers for the S4? I bought one from eBay at the end of last year (item no
151128038769), and it was fine for the first few months, but now it doesn't seem to charge the phone at all. I get a popup message when the phone is placed on the correct part of the charging mat (although this message doesn't always pop up as reliably as it used to), and the charge indicator displays in the notification bar, but if I return to the phone half an hour later it has actually lost charge.
I've tried this with two different charging pads, from two different manufacturers, and neither charges the phone, even though the phone gives the impression that it is being charged when I first place it on the mat. Charging using a cable still works fine.
I was wondering whether others had experiences of wireless charging?
Update: I just checked the charge status with the Galaxy Charging Current Lite app. When the phone is on the pad the charging current shows as 640mA (which should be enough to charge?), but the phone is actually losing 1% of its charge every few minutes.
???
are you using an adapter cover or a connector for the qi charging?, maybe they're not aligned well
also,i just checked and i get 460mA via simple usb/PC charging. and it's still charging. (really slow, but charging.)

I'm using a receiver insert. It sits on top of the battery, and has a flap which covers the charging terminals higher up the phone. I'm more than happy with 640mA as I usually charge it overnight. I just don't understand why it's losing charge instead of charging.
if it's charging with 640mA, but still your phone is discharging, then maybe your phone is draining the battery.
try to close everything, such as wifi, GPS, mobile data etc. and then check if it's still not charging.
also, you can try changing to a a different receiver, if you have one
btw, what about normal charging? does it charge normally?

Yes it seems that there's something that's draining the battery faster than the Qi pad can charge it. I've tried a reboot but it made no difference.
"Normal" charging using a USB cable is fine (and quick). I've just set up the Better Battery Stats app to see what's causing the drain while it's on the charging pad.
I don't have another charging receiver to try (only another charging pad, which exhibits the same behaviour)
I have fast charging enabled. I forgot to charge my phone last night and put it on the adaptive fast charger this morning at 0809. It was at 3% when it started. It's 0958, and it's at 22%. The phone has been power on during this time, but it should be faster than this. The setting for fast charging is checked.
Is there an indicator letting you know fast charging is engaged? I thought he gave a notification when fast charging is on. I know it worked once, and I saw one.
That strange
It only take 30 mins to charge 50 percent
Make sure you turn off all service and turn on power saving or shut down your phone
When I plug my note 4 in to charge a notification shows saying fast charge mode enabled (or something along those lines)
And it appears to charge really quick, I can't be exact on time, but my fine was down to 15% last night before I put it on charge, must have been about 15 mins and it was about 35%
Once I think it charged 20% to full in about 50 mins

That's what I thought. I thought I was imagining things when it didn't appear or maybe it only appears upon first use. I even thought maybe using Nova was some how suppressing the message.
Given you response, I thought maybe there is something wrong with the power in the computer room, so I took it to the kitchen. Then, the status message showed saying fast charging is on. Weird. So, I went back to the computer room and plugged it in. Now the message is starting to appear.
I guess the adapter glitched and was stuck in lower power mode. Not sure. Any way. Thanks for confirming the status message. It seems to be working now.
While my charger seems to work fine. I have noticed it wont pull more than 1000 ma at any given time. I was under the impression that when my battery is below 50% i should see fast charging at a rate over 1000 ma? I get 1000 ma off any decent tablet type charger, including over 50%. Yes fast charging is enabled and detected when the phone is connected to the fast charger.
Anyone else seeing this? Using "Galaxy Charging Rate lite" from the app store. Is there a better app that you guys like?
UPDATE: on a 2A 5v charger I will pull down average 1800ma when the screen is off, then it drops down as the screen is off. So, more testing is needed on the fast charger, I think I need a application that will log the ma draw at intervals to see what it pulls during "fast charge mode" with battery < 50% on the samsung charger.
Fast charging mode only works with screen off!
Charging at 9 Volt and around 1000ma
With screen on the fast charging mode goes off an charging goes to normal mode at 5 Volt and up to 1800ma.

I'm sure I read somewhere on XDA it also only works from 0 - 50%.
Going from my own experience, when I plug it in, I definitely see the "fast charging enabled" message appear in my notification bar.
However it's anything but fast. Mine has never charged faster than average speed that I have noticed, but then I rarely dip below 50% if I can help it, so that might be why.
Last night I put it on charge at 1am (at 59%), came back at 01:48 and it was on %93. Is that good? You tell me. It doesn't seem it. Perhaps my expectations are too high.
One thing I was always curious about is would it matter if you use an extension lead as opposed to plugging it directly into the mains. Not sure how much voltage it is able to draw though an extersion lead, but as must of them are supposed to be up to 240 volts, I'm guessing that wouldn't make a difference.

Are you sure, I go from 5% to full in around 80 minutes with device on, is yours faster switched off?
On my Verizon Note 4 phone running Android 5.0.1, if I go to settings/battery, there is a setting for Fast Charging which you can enable if it is not already. Just below that, there is a status message that when the phone is plugged in will tell you what kind of charging you are doing. I just plugged it in with an Adaptive Charging unit and the status said "97% Adaptive Charging" indicating my phone was 97% charged and was charging using the adaptive (fast) charging. When I unplugged it and plugged it back in with a non-adaptive charger, the status changed to say "97% - Charging (AC)" indicating it was charging but not "fast" charging.

If your USB adapter is plugged into an AC outlet or a long AC extension cord that is plugged into the AC outlet it makes no difference. However if you were talking about a USB extension that plugs into the adapter and extend the length of the DC USB cord that will make a major difference.
