A strange problem I've had for about 3 months.
If I plug it in to the car charger (even keeping it in standby mode or off) it drains the battery in from full to empty in just over an hour.
Tried different cars
Different chargers
Different ROMS
Charges ok of computer usb
Charges ok off powerpoint
Has anyone else come across this problem?

Hey,
Anyone having the same issue ?
It's very strange because it happens somedays, someothers not at all.
Basically I plug the note to charge, it displays charging, but when I come back an hour later or so... the note is at 1% charge, like it just depleted itself and is just living out of juice sucked out of the charger...
This happens when I plug it in the wall charger most of the time.
When I plug it through USB on my computer (lower charging output) it never does this. And that's also how I managed to recharge my battery to 100% after the first time it did that.
But a week later, now it's the second time and it start to get annoying.
Anyone has any idea ? Is the charger defective or the battery ? Or worse the battery controler ? Anyone knows how to reset battery stats on the galaxy note ? Thanks.
I had the same problem on another type of phone with a usb charger
Would charge sometimes, sometimes not fully charge and then sometimes not at all.
Turned out to be the charger, just get another charger from somewhere
(I find the 10Watt/2.1amp IPad Apple chargers are good quality and provide heaps of juice for quick charging)
I don't actually suffer from battery life problems like some other owners. My problem is that it takes for ever for my phone to charge. My phone has been charging over USB attached to my computer for 8 hours and is only at 83%. When it's attached to the mains it's pretty much the same story. I'm not running any apps. 3G, WiFi and Bluetooth are turned on though.
How can I resolve this problem?

well, if plugged into a computer/usb, itll take much longer to charge. are you using the original usb chord? when plugged into a wall charger, how long does it take?
Current draw is about 700mah on average. Battery size is 2100mah. So it should take 3 hours to charge with the wall charger.
USB is another story. If you charge and surf at the same time it will be consuming battery rather than charging.
The problem seems to occur when I don't use the original USB wall charger. Are not all USB chargers the same? When I use the original charger, I don't seem to have this problem.
If WiFi was left on while charging on a computer USB port, would this effect the charging speed?
I've tried charging with its original charger, as well as a RocketFish 2.1A charger. I've also tried different USB cables with the same results. The battery stays at 0%, even after hours of charging (and while turned off). The weird thing is, this only seems to happen at my parents' house. My tablet seems to charge just fine at my apartment, albeit very slowly. But at my parents' house it just doesn't charge at all. Any electrical engineers here? I simply can't see how charging at a different house should cause cause problems. Has my battery gone bad? Should I send in for a warranty replacement?

You mention adapter but are you using the original USB cord?? It is very different from other android cords. Also have you tried different outlets at your parents house? Are you in the US or Europe? What do you mean by slowly? It won't charge as fast as a phone due to the larger battery size. I haven't timed it because I charge while I am sleeping but I approximate it between 4-6 hours for a full charge from 0%.
My Nexus 4 charges at full power when plugged directly into a wall, A/C adapter in a car or to a power strip in a wall. However, it is quite erratic when plugged into APC UPSes (tried several of them). Most of the time, it indicates that its charging at USB strength and not A/C although sometimes if a unplug/replug it in enough times, it will show A/C charging. Worse still, a decent percentage of the time, it gets in this rapid charging/not charging or AC/USB charging mode which actually drains the battery. I've ruled out the power cord/adapter and it definitely only happens when connected to the UPS (both the battery backup side and non-backup side). Anyone else experienced a problem like this?
I own a Galaxy S2. I have tried it using for navigation many times only to find that the battery discharges fully within 2 hours even if the phone is connected to a car charger. I used to think may be its because my car charger doesn't provide enough current to maintain the charge. But recently I found out the culprit. After around 20 minutes of use, the phone battery starts heating up, and it stops charging. I verified this with CPU-Z. It clearly shows battery overheated, power supply connected and not charging.
I was wondering if S4 also has similar issue. Has anybody used it for more than 2 hours with Google Navigation continuously while connected to car charger?

The most I have used it for is about an hour and half, and while the phone did heat up, it did continue to keep charging while connected to my in-car charger (just a cheap one). I can't remember whether the charger was able to keep up with the discharge though, I think it did. I was driving in bright sunlight, so I had screen brightness on max throughout that time.

I've found that the USB cable can have a big impact on the charging current. I had the same problem with my car charger not keeping the phone charged, even though I was using a 2A charger. When I changed the USB cable I managed to quadruple the charging current (from 300ma to 1200ma) and solved the problem (I measured the charging current using the Galaxy Charging Current Lite app).

In my case, I believe it was not because of the charging current or cable. I was trying with a car charger capable of charging a laptop, using the wall charger and cable which came with the phone. When the mobile stopped charging, I checked in CPU-Z app. The app was clearly showing status as "power supply connected, not charging and battery overheated". If I unplug the USB cable and connect it back, it will start charging again!
To make sure that I didn't miss anything, I will try with the app you suggested.
Just to update: The Galaxy Charging Current Lite doesn't seem to work with my Galaxy S2. It doesn't show any value.
