Charging unable to keep up?

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.

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.

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.

Looking for USB Car Cigarette Lighter Adapter

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.

2.1 amp car charger question

Bought a dual charger for the car, has 1 amp and 2.1 for devices like tables. When I plug the Tab Plus in the tablet gives me an X for charging and doesn't charge. Tried different cables. Any ideas??? GT 6210

Not compatible mHa...
Sent from my GT-P6210 using Tapatalk

So only Samsung OEM car and wall chargers work??? I even trid a lower amp charger in the house figuring it would just take longer to charger, and still get the X if it's not the Samsung wall charger.

2.1a is plenty to charge it, but as you said, only Samsung chargers will do it. It is highly annoying.

Interesting to note:
When the Tab/Tab+ is connected to an HDMI adapter (either dongle or stand version: I have both) the tab will draw power from ANY USB source and show it as charging. A generic 2.1 amp charger will add to the battery even while playing MAME on my HDTV using a BT PS3 controller while WIFI is enabled (a 500mA charger works too but cant keep up....in other words it will deplete your battery...just slower). The same generic charger will NOT charge my Tab+ when NOT connected to the HDTV/HDMI adapter.

It's charging, but it's only pulling 450mA. This is a safety measure to prevent pulling too much current from a computer USB port.

This is nuts. If it charges through an HDMI cable??It charges slowly through a computer??? I'm surprised nobody has come out with a "charge only" cable so it works generically. Obviously some of the pins can be left off or crossed to trick it.
I'd buy 3 and keep them all over the place!
I've seem them for Apple,I devices, even was shipped one by accident for my Ipod.
I'm writing CableJive! Maybe if they hear from enough of us they support out product. '[email protected]'

Eureka! I grabbed an old USB version 1 extension cable (female to Male) and plugged it on the end of my Tab sync power cable. Plugged it into Tab OEM wall charger, worked fine. Then I plugged it into a generic wall charger for phones (1amp) and IT IS CHARGING!
Still won't work on car adapter, tried 1 amp, 2.1amp, and 2.2 amp.
Ordered USB 2 extensions to test.

Have you made sure that the plug will charge something else? Make sure it will charge your phone or something. I know those dual micro-chargers have to be pushed with a lot more force than you would think. I would also check both ports on the dual charger. Usually only one of the ports will output 2.1 amps while the other only outputs 1 amp.

Quick semi-related charger question: are all Samsung Tab chargers the same? Or, at least, are they cross-compatible for charging?
I've got an imported tablet, and it's charging very slowly with a UK adaptor (which was supplied by the import company... had been expecting more, I have to say).
If I tool up and go shopping for a genuine Samsung Galaxy Tab charger, will any of them do, or do I need to be specific? Does anyone know?

i got one of these handy.

i bought it from DX few months back. http://dx.com/p/usb-power-adapter-for-samsung-p1000-81753?item=1
and it charges my fone with any usb chargers i have.. i also use it for my 2.1A car charger and works as expected.

I second the adapter recommendation shown above. I just wish it had some way to tie it to the cable so it doesn't get misplaced. They're pretty cheap, though, so I bought a couple extra.

here's mine..its tied with my extra sync cable.. these adapters are fragile and one of the plastic clips broke.. secured it with a zip tie and now even when i dropped it several times the white case stays secure.. i bring it with me all the time...

Have you guys tried these adapters both on AC and Car 2.1amps WITH the Tab? The references I see above are for phone.
Oops...never mind, went to sight and saw a reviewer listed Tabs.

Fast charging not working (not cable or charger)

My gf's S6 doesn't fast charge anymore. I have a S6 too and tried cables, chargers and different outlets so for sure that's not the problem. I've made sure the plug is all the way in so it's not that. I'm going to contact Samsung because we're still under the year mark but there is a small possibility some water may have gotten in the charging port. With 3 kids it's tough keeping your toys away from them all the time. Anyone hear of any issues with the fast charge not working? Most of the threads I could find about this issue is resolved with a new charger or just plugging it all the way.

I havent heard of any issues with id just take it in and dont say nothing about water.

noticed that there's no fast charge :/ stock USB cable with stock charger!! my previous S4 did charge faster :/

S6 have fast charge QI? I don't think so guys.

Check this, I am on 6.0.1 and not sure if there is an option on Lollipop, if you are on Lollipop. It's in the Battery settings.

Good evening everybody,
Appologies for attaching to this post but my question is about fast charging in G920F I own, too. When I use stock AC quick charger and stock Samsung cable, my phone charges quickly (not a surprise). But when I use stock quick charger and other microUSB cable (e.g. the one I got with the Chromecast 2), S6 charges in normal "slow" mode. Does this functionality depend on the cable?
Thanks in advance for a reply & best regards.

It depends on 3 things. The phone, the charger and the connection (th e cable). So yes, the cable is a crucial factor in utilising Fast Charge
Think of it as having a fast car, a driver comfortable with pushing the car to the limits, and the road being the cable. If the road isn't build for the speed (let's liken it to a country ally/road) you can't safely drive at top speed. So you drive at the safest speed you can with the road you have. That's what the phone and charger do. Rather than blowing the cable (which could happen), it just draws a smaller amount of power to keep everything safe.
Sorry for the big reply. I like to be as informative as possible in one go

Well I tried Samsung wireless quick charger and still no luck. Guess I'll have to send it to Samsung.
Not on Android 6, still on 5. Thanks though

I had the same thing happened to my S6 two weeks ago. It charged only slow way, even with a fast charger, and i tried few cables and solutions. At the end i took it to warranty and they replaced that whole board with USB port. It was done in 24 hours and now it works like new. They even gave me brand new Fast charger and cable for free. Good guy Samsung .

Droid turbo fast charging help need

need help.I bought tronsmart qualcomm quick charger 3.0.It charges some time my motorola droid turbo with fast charging as it says turbo charger detected and some times it charges like a normal slow charger.70% time charging is normal and 30$ its fast charging.Can anyone tell me the reason about this?

When the battery is low, it will turbo charge VERY fast.
When the battery is near full, the charger will charge at a more normal speed.
However, no matter the speed my phone ALWAYS detects the "turbo charger", as I'm running RR 6.0.1. It always says "turbo charger connected" when I plug in with a fast charger. I just plugged in with 95% full battery: "Turbo charger connected"! Of course, at almost full battery capacity it will not charge super fast -- even with the Turbo charger.

If I charge with a "regular" charger, like my Qi wireless charger, it will not give that notification.
Your observation of 70% (normal charging) and 30% (fast charging) seem reversed, unless you are plugging in a lot with the battery at 80% full? But even then, your phone should detect the fast charger and give you an on-screen notification -- even if it doesn't charge as fast as when the battery is very low.
Are you not seeing the on-screen notification (toast) when you plug in?

Yes i see notification 30% but not everytime.so i open turbo toast app and verify if it is turbo charger detected or not

So, when you plug in your fast charger (turbo charger) you do not see the on-screen notification (toast) every time?
Since your are using RR 6.0.1 which has @bhb27 Turbo Toast app, do you have all these boxes checked on Turbo Toast?

Yes these r all checked

A bad or low quality cable can cause this to happen. I had a bad cable in my car which caused my phone to charge slowly... I replaced it with another one and everything is fine again.

Thanks i will try changing cables

Yes! Sometimes we forget about the USB cables. We think "a cable is a cable".

Buy one that comes from a major phone manufacturer, one that's branded Motorola or Samsung or LG or HTC. Not simply a cable that's "compatible with..." or "for..." a major brand, but one that's sold by them, packaged with their logo and has that logo molded into the cable end.

In addition to the other recommendations, Monoprice.com makes very good cables, in general, too. For this test, I'd suggest just getting/borrowing a cable from someone else and seeing if that fixes it.
