When I'm using google navigation in the car and the screen is inevitably on full brightness I expect the battery to drain really quick. So I plug in the car charger expecting all to be fine - wrong! The battery still goes down - just not as quickly.
If I am on the road for about 6 hours the battery will go flat. My car charger is 800mA so it should be no problem.
Is it just mine?
My Epic was the same way under heavy load.

Never had that problem with my Nexus One and would be surprised if the Nexus S exhibited that behavior. But my Nexus One dock came with a 1000mA charger.

It's pulling more than the charger can keep up with. A beefy charger like ones for the ipad might help but unknown how much. Griffin makes some that can output over two amps. Look at best buy. Make sure you check the output ratings. Some might be more than others. You will have to use a usb data cable as the cord because the one I'm talking about has standard usb female on the other end of the adapter. Griffin power jolt.

This particular one has led that glows red when full charging and green when trickle. There's different models.
The Nexus S isn't even close to how bad the Epic was. A road trip with Google navigation on, and the screen low would eat at the battery. Heavy use in general would eat at the battery. All while the screen brightness was at like 15%. I felt like the phone was always in a constant state of charging, except overnight when I slept.
Nexus S isnt even close to that bad. I wouldn't even define it as bad at all. Just normal. I would just avoid maxing out the screen brightness. 25% is normally enough in 80% of your situations.
Sent from my Nexus S 4G using Tapatalk
I use a 1.2A charger in the car and also have this problem. Only with Navigation + max brightness. If I drop the brightness (at night) I can stay ahead of the drain.
This was also an issue with my Vibrant so I was not surprised to see it on the NS as well.
I read in one of the posts about an app called battery monitor widget. It has been a helpful tool to monitor the charge discharge rates. I highly recommend it. You know when the phone is truly idling and when something is pulling down on the battery even when you're just sitting at the home screen doing nothing.
I haven't found a useful essential app for a long time until I stumbled across this.
I've had the same problem on the stock charger O.O! You would think that the one that came with the phone would be able to handle it running as a wifi hotspot but it doesn't. My old phone, an HTC Desire, never had a problem keeping up.
Yeah Samsung phones takes too long to charged I though my evo was bad cause I came from an ip
hone, which charges in an hour (80%) and now battery kills me in this phones

Sounds like the crappy 3G/4G/wifi is the culprit. I believe when they fix the signal issues battery drain will be reduced.
P.S. Come on Google... WTF!
I noticed the USB connection will not keep up, but the AC connection will. I know that doesn't help in the car, just an observation.

A lot of car chargers output like ac chargers..like what came with my car dock.
Sent from my Nexus One using Tapatalk
Guys, make sure it's charging in AC mode so charging can keep up with the discharge rate. You can see whether it's in USB charging mode or AC in About phone > Status. If your phone is in USB charging mode while plugged into the car charger, it means the D+/D- pins of the charger cable is not shorted.
You have several choices:
1) Open up the charger and find the USB wire solder point, short D+/D- (usually the middle two of the four pins) with a soldering iron.
2) Skin the USB cable/wire, cut the D+/D- wire (hopefully you know which two), and short the openings.
3) Buy a male and a female USB connector, solder the two together, but short D+/D- on each side.

I have had about 5-6 of these.. every one I get my hands on is junk. When using the GPS, with the phone pluged in (non stock cable) I still end up killing my battery dead. The second it comes off the charger is turns off.
Can anyone point me in the direction of one that charges correctly?
Thx in advance!
I use my wife's from Verizon and it seems to work ok. It has a USB port so I can use my normal, thick data cord. You're probably running into ones where the cord is too thin to give proper charge. This one works great with the data cord.
I have the Samsung car dock. It seems to do fine with just GPS. I don't think the Epic can draw enough current to maintain it's charge if you're using any other features. If I'm running GPS + Streaming Music, it will discharge eventually and become very hot.
You need
1. a reasonable quality USB charging cable so that the Epic will draw the maximum current, or a power adapter that grounds the data pins. If the epic thinks it's connected to a computer it won't draw the maximum current.
2. an adapter that will provide 600ma+. I used the one from Griffin until it broke* and I bought the Samsung cradle. http://www.google.com/products/catalog?q=usb+car+power+adapter&hl=en&um=1&ie=UTF-8&tbm=shop&cid=1150301903319147928&sa=X&ei=4h0ZTtSyL4aDgAeA7rH0Dw&ved=0CIUBEPMCMAE
Hope this helps.
*Griffin agreed to fix it, but it's been several weeks since I sent it in. I'm a little unhappy with them at the moment, but the adapter was fine until it broke, maybe you'll have better luck.

seems like a good price. i ordered 3 single usb 1 amp units for 1.99. I'll give feedback once there in my hands.
sounds weird but goto radioshack or wherever & get one for a palm pre it works great charges really fast to, try & get palm brand because thats what im usin
Not as strange as you might think. As the pre/pixi charger is 1amp allowing it to power the touchstone with enough current. Most
12v lighter plug USB adapters are .5amps.
Also the pre/pixi lighter plug charger requires the cable that comes with it. And although it is a micro usb the end that goes in the lighter plug is not standard its thinned and narrower.
+1 on the pre charger... been using one since I had the pre, and it is awesome. phone still discharges when streaming pandora and running GPS, but GPS by itself results in a very slow net charge on my drive to work.
We sell a case logic brand charger at work for 15 bucks that is rated at 800mA, used it a few times and know a few people that have one. I'm sure online price is cheaper.

ive never had that problem mine always charges no matter what
I get mine off of EBay. Just make sure its output is 1amp.
USB and DATA cable
That's because if you use a USB adapter and a DATA cable the phone only charges at half it's rating. This is because it thinks it's pulling the power from a computer USB port and it doesn't want to overload (and fry) the port.
I picked up one of these, opened it up and soldered the two middle USB pins together. Now it allows my phone to charge with a data cable at it's max rate.

there are pretty sweet power inverters that run 30ams, so you can plug in laptops and such. pretty compact, AND they come with 2 usb charging ports.
there under 50 bux.
I use a j-lo brand car charger. Its for a gps and charges @ 1000mah. I also have a power inverter, the cheap one from walmart with 2 ac outlets and 1 usb port. Both of these work very well.

Efficient output is just 500-700mA? Too small to charge N4?
I thought the standard one is around 1A or over.
Thanks.
500-700 mA is perfectly ok for charging. When you charge from a computer via USB, the max current is 500 mA unless you use kernel tweaks.

It's got to depend on the output (mA) the USB power adaptor has to offer too. They even show it connected to a laptop USB port. So I think it WILL charge, but maybe significantly slower than a direct power connection.
By using a lower output USB power supply, sounds like you might be able to trade charge speed with temperature rise. If so it may be ideal as a charger to keep your phone topped up. Kind of like a low power trickle charger, which would be fine if my phone is on it most of the day... I actually don't like the idea of Qi chargers that make the phone get hot - seems to be trading convenience and wear on the phone's USB connector with reduced battery service life as it keeps going through nasty heat cycles?
Decided to risk it and order one

I agree, Used in a car with GPS on, maybe pulling 3G data for maps, bright screen, etc., it's likely that despite this charger, the phone will slowly go flat. And get hot doing so... All that energy from the battery/charger has to go somewhere - mainly heat once the battery is charged. If the phone's consuming, say 750mA at around 4.1v battery voltage, that's around 3W of heat to dissipate.
I am investing time looking for a Qi charger but that problem appears to be present on several cheap alternatives, the current they supply is not enough, or you might expend a couple of extra hours charging your phone
Just a quick update, ordered from fast tech on Jan 29th and received shipping notification today (Jan. 31st), registered airmail with tracking from Hong Kong post.

I do have this wireless charger. Ordered from aliexpress, it's always the same with different branding and logos.
It does the job, charging.
But:
Need to be very precise when positioning it
Back glass make the phone sliding, and cancel all the effort offered in the above point, making the phone not charging
I recommend to wait for a charger with more than only one wireless charging chip/antenna.
Ok I have this charger now. On first charge and working ok so far... Seems to be best in this position. Has now cut off an an indicated 99%...

Lining up the edge of the charger with where the bottom of the LCD is, seems reliable. Using an XtremeGuard style protector on the back, which gives enough friction to stop sliding if the charger is horizontal and the phone vibrates.
Above is FastTech image. I'm using stock N7 charger and cable at the moment because it was handy. Unit came with a USB charger and cable (with EU plug - I'm UK based)
----
Picked up phone and used it to 98%. Returned to charger and it charged back to 99%, but didn't beep this time when charging started. Maybe it needs to be more discharged before this happens....
----
Now at 100%. Charger seems to poll the Nexus about every 30 secs (solid blue light for a few secs) to see if it needs charging. Then light goes off. When it charges, the blue light flashes slowly but continuously.
Did anybody try the Large models?
For some reason they are cheaper even though they come in black or white and have the Qi logo/writing on it.

Hey, I don't know how to force to charge tablet in the car.

I know trick to mount USB partially, sometimes it works and there is no red cross, however I noticed in Battery Monitor Pro:

You see tab's been plugged, it shows "USB connected" and "Discharging" however power depreciation is still high.
When there is no red cross (I mount USB stick partially). Then charge rate is very low - 0.5-0.6 ampers instead of 2.1.
Charger is working good, I tested it.
How to force it to be charged at full rate? I worry about GPS power consumption - Sygic+Locus Pro = more than 1 amper depreciation, so this is matter of time till tablet will go off. The worst scenario... during road trip.
You need something like this with 2.1 amp

Thx, but are you sure that Dual USB charger will give me full 2.1 amper (or min 1A)? I have 2.1 A charger but it gives only about 500-600 mA. I've heard due to USB cable pins made for Apple products (even if it is universal one).

I just played around with making a wireless charger. It is 1 amp and it will charge the 7" tab2. My 850 mah wall charger will charge it as we'll. both show an x over the battery but they charge. The secret is the data wires. They need to be connected together. I modified a cable for a car one time to do this, but many car chargers today do it for you.
The tab 2 will charge off less as it can charge off a pc USB port at only 500mah, so it is not the amps.
Possible solution for chargeing issue

Pardon me but but you have a Samsung Galaxy tab 7 plus looking at your other posts. My P6200 only charges from 0.9A lower limit to 2.02A upper limit at 5vDC if your amps go lower or higher you get that red cross
I get best results at 2.0Amp charge and no more. otherwise battery only takes in 0.5 to 0.6A which I see you observed the same with battery pro I did it with a external power supply that reads drawn current

New One S owner here. I'm finding that when using my One S in the car running Google Navigation (GPS), the battery is draining even when plugged into my car charger. I specifically purchased a name-brand, 950ma charger to try to avoid this problem (using this charger from Motorola), but it still seems to slowly drain if I use navigation, have the display on, etc.
Does this happen to anyone else?
Any recommendations for chargers that WILL work?
You'd really want a 2 Amp charger for that I think, 950mA is only just enough to charge the phone when it's not in use.
Latest update: I purchased this Powergen charger, which is supposed to be able to deliver up to 3.1 amps.
Tried it last night in my card running Google Navigation, and the batter STILL drained; slowly, about 3% over 45 minutes, but it was indeed draining. Wasn't running anything else except Google Nav; screen was on (obviously) and I did have bluetooth enabled and paired with my car's system, but I wasn't using the phone for calls.
Guess I'll repeat my request:
Does this happen to anyone else?
Any recommendations for chargers that WILL charge the phone while running GPS/navigation apps?

Yep, I have the same problem, although for me it's draining like 10% / half an hour. This is pretty annoying. My device also gets very hot (very hot = 50°C +)
I have a brand charger from Hama, so I really don't know where the problem is.
Same problem here too. Charging isn't possible (-10% per hour) and it also gets really, really hot. Don't know if I should charge my phone any longer because of the heat... Has anyone got a solution yet?

This might be a flaw of the phone. Happens to me too.
So you think it's okay charging the phone?
I have found the same thing. All my DC chargers will not charge, only maintain a slow drain, with GPS running.
However I have a monoprice external battery pack model 9531, that does charge even with GPS and bluetooth enabled. I have also noticed that using this in other circumstances it charges the phone faster than any of my AC chargers as well regardless of the state of the phone.
I could not like the monoprice page for it but I believe they still make it. Here is a picture. Hope this helps.

Has anyone tried GPS with Bubba or some of the other kernels that have fast charging? Maybe those would do the trick?
Most Car chargers are internally wired for Apple products ( data ports have current on them tot tell the Apple product what the charger capacity is ). Android phone do not recognize this, so they fall back to USB charging (500ma).
Look at the phone battery settings when charging. Doesvit say USB or AC ?

Anybody try swapping out the cable
Same. Unplugging the USB from the wall brick and reconnecting usually fixes the problem for me.
Same thing happened to me. Saw the tip of the Micro USB part, and it looked kinda weird, not all four wires aligned. Went to the drawer, got an old HTC wire, hooked it to the Samsung fast charger block, and it worked like a charm.
Pissed cuz I purchased 2 multi port fast chargers on amazon which no longer fast charge after the update.
I had mine stop fast charging once. I checked the connections and all was fine. I tried the Ultra-power saving mode and could not turn it back off. I ended up factory resetting. Since then - I have had no trouble with my fast charging working every time.
I have experimented with different USB cables and found that Fast Charging requires the use of USB cables that also allow data transfer. There are some USB cables out there that only has normal charging capability and these do not work with Fast Charging. Sometimes you can tell by checking the microUSB pins, others they simply lack the wiring within the cable itself.
Normal charging cables must have Vcc and GND for electricity passthru. While Data cable has additional D- and D+ connections, which I believe is used by Fast Charging.

I've had similar issues and ran many many tests. Using stock charger when plugged into phone and power 100% of time doesn't fast charge unless I pull USB from wall adapter still leaving plugged in both phone and wall. Plug USB back in adapter and fast charge will work 100% of time. Tried many different cords as I have lots.
Sorry to resurrect an old thread, but I have problems with my Note 5 no longer fast charging much. Over the last few weeks, it has charged progressively worse.
-I ordered a new cord and have tried multiple different cords and chargers including OEM. I was leaning toward this being an issue with the ports needing cleaning, but have now observed the same issue with wireless charging. About half the time on wireless charging and 3/4 of the time with wired charging it is very slow with no fast charging.
-I have also factory reset (using TekHD rom and modified stock kernel though I also tried Skyhigh) and am still having the issue. I use my phone all the time for work and am about to get rid of it. But before I do, does anyone have any ideas?
In summary: Fast Charging is intermittent with multiple cords, OEM charger, and wireless charging. Any ideas?
Get a new USB cable
In my experience, Samsung cables have a short lifespan. LG & HTC cables do better IMO (Probably because when you buy a LG or HTC there isn't many fakes Even on amazon many samsung clones) but I find LG cables work best. Yes, you will get fast charging with them
