Strange Issue!!
when my phone is low on battery and i try to charge it (with the original ac charger or the usb); sometimes (almost half the times) the phone instead of charging .... DISCHARGES!!
i have tried all possible fixes. tried the battery calibration apps also. but it gets ok for a day and then back.
i can only charge my phone while its switched off!
Details:
1. on stock TW4
2. 3 pages on home
3. total widgets= 6 ( advanced task killer; digital clock; 2- circle launcher; quick battery; weather)
4. i kill all tasks always before charging!
WHAT AM I DOING WRONG? BTW I HAVE TRIED TO REMOVE ALL WIDGETS AND CHARGE ALSO! NO LUCK!
HELP!!
It sound like you might have a faulty charger, have you tried charging from your notebook, it`s a bit slower at 400mah compared to 650mah for the mains charger.

Yes, as a matter of fact, right now i am trying to charge through USB with the same drainage.
Switch the phone off for a while!... let the sucker charge.
And the problem is not always!
this is normal, already been posted. the charger is limited to 650 mA on wall power, and 450 mA on USB power. so it is easily possible to pull more power than is going into the device, say if you are gaming or pushing the device hard with navigation or similar.
next time this happens, turn off the screen for 10 minutes as a test, then come back, and see if the charge increased at all. it likely will increase.

yup! i was having the same problem and did this Roger says and its exactly that... GL
if your phone is hot too it will not charge as well.

My problem is when I'm not using the phone at all and the screen is off. Tried charging through both wall and usb charger.
The only way right now I can charge my phone is while switched off.
I always kill all apps before charging also... Still!
And if its charging while on, screen off, it gets hot also.

Edit: i also have read in many places that using task killer actually cause more harm than good bcoz it disturbs the proper sequece of how android shuts down an app or process..and cleans up the memory..this will result some of the apps or process to stay awake or come awake again when it sould be sleeping...

I once had this problem..after charging for 6 hours battery was only at 60% and phone was hot..found out that although the screen was off..the phone was wide awake all the time. For me the issue was the wifi manager was somehow awake and consuming power..hence phone was hot and battery drain while charging. Check your battery usage graph and see if your phone is awake when it should not be..and pin down the rouge app or process..
Hope this helps..

I've got a similar problem, while charging in a car using the SGS2 for navigation. BTW, what is the maximum Amper I can charge the phone without damaging it?
I really dont understand why Samsung keeps supplying this crappy charger. Desire Z and iPhone 4 both came with 1000mAh ones. Super fast charge on both! Come on sammy... This isnt a 900mAh feature phone. This is a big battery hogger dual core with a large battery inside!

I am using HTC's 1000mA charger and still,this happens to some extent,only much less.Try overclocking the hell out of it and then start benchmarking.Charging?Hell no.You may even need to draw power from the house next to yours!

I read somewhre in this forum that samsung has set a limit of max amperage on this device to below 700 miliamp( cant remember the exact value for ac charging and usb charging) so thts why the charger is rated to 700mah

That's right,but if the charger was 1000mA like HTC's it would continue to draw those 700mA it needs even while in use.You wouldn't notice any difference at all with it charging while not being used,but when screen is on there is a difference.
They limited charge current to 650 mA in the driver code, so that's why they use a 0.7 A charger. Using a higher output won't help unless someone compiles a new kernel.
I charge the phone until 100%. When unplug, it immediately drops to 85%-90%. On one occassions, it dropped to 40%! What's wrong with it?

Thanks. But...i tried charging it whilst it was turned off. The icon showed 100%. I then unplug and switched it on. The same happened. So, it should not be Apps related. Right?

I suggest you do a simple trouble shooting...charge your phone to 100% while it is off.
Than unplug, switch on your phone and just leave it for half hour or an hour without doing anything.
Than swith your display on...and go to settings
Select about phone..
Go to battery use and tap on the graph.
It will show you a few horizontal lines.
Make sure your screen on and awake time bars coincide nicely.
While your screen is off your awake bar should be very very minumum... most of the high battery drain casses will have a very short screen on bar but a solid long line of awake time.
This is normally due to some rougue app or process...and you have to narrow it down.
If your graph looks normal..than you could be having a defective battery or in worst case a defective hardware.

The max of 0.7 amps is a partykiller... When in my car, I'd like to have my phone record everything (dailyroads voyager as dashcam), while navigating... Definitely discharging there while on stock carcharger! So I will have to choose when I'm going on holiday (12 hours drive...)

I had a same problem before. But after I reflash 2-3 times (literom 1.5 for now) it's gone, and charging normal on car and wall charger while gaming or navigate.
Does Nexus 7 run directly from USB or charger power when connected to USB cable? Or is it so that the device continues to run on battery while the battery is simultaneously being charged? This is an issue related to the longevity of the battery. The easiest way to test this is to try and run the device on DC power while the battery has been removed. I have neither the tools nor the guts to check this out. Suggestions from anyone and everyone are welcome.

Humm... Interesting, it stayed on. If i restart without a battery it will actually restart to the home screen but then restart if u try to click on anything.
So I guess ignore my first post, these are different results then I got a month ago.

Battery settings shows "X" seconds on battery and that X never changes if the tablet is connected(to PC/charger), no matter what you are doing. I connected the tablet to PC front panel USB, switched it on, it showed 100% charged and 0s on battery. Now I fired up Stability Test and after an hour or so battery settings showed 95% charging, 0s on battery. Your and my findings establish a point, i.e. The USB power provides direct power to the tablet upto a certain wattage, beyond which- as in case of a demanding load- the battery also/solely provides power. The battery is always being charged in background if it is not already fully charged.
I installed the official update. After shutting down, nexus4 can't start up. Press the power button over 10 seconds, it also can't reboot. And I pressed the three buttons, it can't go to the bootloader interface. How can I get it start up again?:angel::angel:
I had this when I did my update. It took a while of holding the power button to get it too boot again, try charging for already an hour then hold the power button for at least 1 min. Once I got mine to boot again I've not had any issues since when booting it up.

You can try leaving the phone on AC charger overnight. Some people have reported that they managed to fix their phones that way.
Was it the official OTA update you installed? I suppose your device was not rooted then.

My phone was on USB charge once ( actually plugged into the computer not the ac to USB issue people have been having) and because it thought it was charging it carried on as normal but the battery wasn't being charged fast enough by the USB to keep it running and the phone just died, no shutting down or anything dead with a flashing red LED the reason it did this was because the os thought it was charging even though it was discharging so until the battery actually ran out of juice the phone ploughed on. I immediately unplugged the USB and switched to the AC. The red light went off and the phone was silent for at least 10 minutes. I then with all toes and fingers crossed tried to start it again and it did. The red led lit up and stayed on for about 5 seconds and then burst into life. It really depends from how long you've had this red led if its been like it for a while I'd recommend a straight 24 ac charge with no interruptions. If that doesn't work I'm out of ideas :/ good luck Blewk

i've tried all the power + volume combos...how did you get to bootloader?
If people just let their phones charge undisturbed overnight and tried the next day to boot, that number would be -80%..

That would brick basically any phone. You don't play around with flashing the bootloader unless you're sure.
Got the red light once while doing benchmarks.. But i was able to get into bootloader mode reflash system img.And bam i was good to go..
Dang man, this same problem is happening to the LG Optimus G. There is a thread on xda for that phone and the op says to take the back cover off, disconnect the battery then reconnect it and that fixes it. Maybe worth a shot on the nexus.?? That is if you don't want to reflash the phone.

Holy crap. It's literally IN THIS THREAD.
Leave it on your charger for several hours and see if it boots. If not, it's probably RMA time.
It's plugged for about 10 hours and nothing.
I live in Brazil, no sells here yet and it was bought on USA.

I was just mentioning other options just in case someone couldn't get into the bootloader. What if you send the phone to lg because you couldn't get into the bootloader to reflash and they can by disconnecting the battery and find out that you are unlocked and rooted when the phone boots back up, which would also void your warranty. Although I would not take the back cover off if the phone was stock, might as well send the phone back if you can't get it to boot.

You seem to know very little about how chargers, batteries and charging circuitry works. To put your mind at ease, a USB 2.0 port is rated at 5V DC, 500mA. That will charge a Nexus 4, albeit slowly. Your 0.7A charger isn't going to fry anything, as there are multiple safeties built in, unless something is SEVERELY wrong with it, meaning faulty construction.

So you are telling me that, unless there is any issue with the charger (faulty construction) there is no reason to worry about that it will lead to this "Red light of death" or any other issue (lowering battery lifetime for example)?
This is totally off topic but, Do you (personally) think it's true what people say that charging a cellphone with a lower output charger increases its battery service?
Quick question:
Does this red light issue appear when battery is drain to 0% (among other factors)

There is no reason to worry unless the charger or your phone is faulty, in other words, hardware failure on either side. Unfortunately there would be no easy to foresee that.
The charging circuitry will only use what it needs to do it's job. As long as the voltage is within range and the current is not too LOW, you're OK. The N4 is rated at 900 mA to perform a standard charge. It will accept as low as approx. 500 mA to charge in USB mode. That idea is rubbish.
Or more like charging issues?
I've got this phone in December and I'm pretty satisfied with it. The only thing that kinda annoys me is the fact that my phone often won't charge properly and I'm not sure if it's because of the charger (the one that comes with the Nexus) or the battery.
When I charge it, it says that it's charging. Just like it should be. The problem is though, that it's not really charging. A few seconds later it says that it's discharging, not even a second later it's charging again, then discharging and it goes like that all the time. I'm almost sure that this harms my battery a lot. When I let it charge over night, most of the time the battery level is under 100% (50-60% are more likely) and that is kinda frustrating when going to work.
So I want to know: does anybody have the same issue or something similar? Or do I just have a faulty device/charger? This issue has been plaguing me for around a month now.

Have you tried it with another charger? I always use a universal charger and that works fine. If that doesn`t help it is probably a hardware issue and you`ll need to get it fixed.

Unfortunately I don't have any charger with an output of 1.2A. All of them are under 1.2A and most are broken anyway (also chargers from my last phone, LG Optimus 2X). Seems like I'm just not that lucky when it comes to chargers.. I'll try to find one though. Thanks for the reply.

Just to test it, use your computer usb. It isn't full power but it is enough to see if there is an issue. Maybe a new cable?

Not sure if this is related to my computer now but when I plug it in it says charging and as soon as the MTP notification pops up it doesn't charge anymore.
Should I try to fully discharge my battery and then recharge it?

Okay so I somehow fixed it.. most likely temporarily but it seems like the issue is the cable. I pretty much "straightened" the cable with my fingers (was applying pressure to the cable and then went slowly downwards) and that apparently worked o_o..
Now it's been charging for 15 minutes without disconnecting once. I hope it'll remain like that..
