Charging while in use (or lack there of)

Is it me or does this thing not charge while in use? I'm using the a/c adapter btw

It works for me when hooked up to my laptop. It goes slower depending on how many resources are being used. My G1 wouldn't charge while navigation was on for instance and my Nexus S barely charged at all while I was navigating.

All I'm doing it texting and surfing. I' trying to charge it before I board my 8 hour flight to Europe. I have two movies on here I want to watch and the charge has only gone down since I plugged it in. It just slows down the rate. I'm starting to think my Galaxy Nexus is a dud. I barely get 9 hours with light use. My brightness is always below halfway.

I guess I'm alone on this issue, or nonissue I should say

With the AC adapter that doesn't happen to me but with the car adapter I can't figure out a way for it to charge instead of lose battery while using Navigation and Bluetooth. All car chargers are detected as USB and I have tried several adapters... (purchased and returned 3 different adapters including Samsung one and have 3 other adapters myself)

bump......

Not charging while on car charger
I'm having the same issue. I find it difficult to believe there are a limited number of us with this problem.

Are you using the AC charger that came with the phone or an old one/third party? You could be running into the same issue as the guy with the car charger(see below). Not all microusb chargers are created equally.

Make sure the car charger you're using is at least a 1AMP charger. Anything less than that and the phone will use a USB charging mode. You can see the ampage of a particular charger on the bottom/backside. Its usually in very small print but its there.
BTW the Galaxy Nexus can actually run off wall paper alone(i.e. no battery inserted) on a 2.1AMP charger that comes with most tablets these days. I use my Galaxy Tab charger for it!

as unremarked said, you need a 1AMP car charger to get it to work. i had to buy a new one.
As far as the AC charger, the one that the phone came with i had issues charging, but i went back to a black berry charger i bought as a replacement for my nexus one, and i can be playing cordy on that and the battery stays charged.

I have a verizon charger leftover from my Droid 1 and I drove across the country a few days ago using navigation 100% of the trip. I also had a few hours of conversation and regularly streamed podcasts and music. I did all of this with the extended battery at a full charge always. The charger was never even noticeably warm. The trip took 3 days and I didn't charge over night so each day started below a full charge.
I suspect you have a problem with one of three things. Either the phone has a bad charging component, your battery is defective or your charger has less output than it claims.

Most USB chargers are only 500mA. Which isn't a lot considering it takes 2100mA just to keep it on.

It's happening again, I can't use this thing while charging. I put it in airplane mode and it still dies while I'm using it. It doesn't shutdown either, it just cuts off. It's plugged into the wall btw.

Yeah I did. I've never had this issue with any phone that I've owned.

make sure it's charging in 'AC Mode' and put a chunk of dry ice underneath it w/ some protection in between.
you are welcome !

If you did, then you'd realize its less likely an issue with your phone and more likely you're using a charger that doesn't push enough power to the phone.

Its the one that came with the phone, 1A 500V, pretty standard these days.

A few comments:
All USB cables are not alike. Not all transmit the proper power. So with your AC adapter, you might try other USB cables to have the phone see it as "AC" and not "USB".
The Verizon car charger does work properly with the Galaxy Nexus, and is seen as "AC" power. Interestingly, if you use the 2nd USB port, even with a cable that does function correctly, it is still seen as "USB" and not "AC". So only the primary connection there will provide full power.
I'm also still looking for a car charger, other than Verizon's, that will be seen as "AC" - I'd get the Verizon one, but don't like the "curly" cord, since I'm duct taping it across my dash, and it's a lot more bulky than a regular straight cord.

If it takes 2100ma to keep it on it would never ever charge on any charger.
Also, considering the fact the battery is only 1750mah that mean the device would only stay on for around 45 minutes before being fully discharged if it wasn't plugged in.
Somehow your figures are a bit off.

How does a USB cable "not transmit the proper power?" What is "proper power" as opposed to "improper power?" Power goes through the RED wire in the USB cable. That's a USB spec. Either it carries current or it does not.
Some devices need to see 2 USB pins to be jumpered in order to set charge on (the Galaxy Tablet is notorious for this which is why you can buy a special cable adapter to create this jumpered charger pin if you are not using their "special" charger. This adapter allows you to to be able to charge the tablet off USB which it normally won't do, faking the tablet to make it think it's on the AC charger, albeit very slow).

What I meant is that using the official Verizon car charger, I connected my Galaxy Nexus with the built-in micro USB connector, and my phone showed it to be charging, and the source recognized as "AC". I then tried connecting it using a couple of different cables, using the secondary USB slot on the Verizon charger:
When I used the cable from my wife's LG Env Touch, my Galaxy Nexus didn't show it as charging at all. It apparently wasn't receiving enough to even be recognized as "USB" charging.
When I used the cable that came with my Galaxy Nexus, plugged into the same USB port on the Verizon charger, my phone showed it being charged, but with the source shown as "USB".
So the type of cable will impact whether or not a given adapter will even charge the phone. And the charger itself also has an impact.
To get the phone to charge, and the source recognized as "AC" you are going to need the right charger and cable. As I said, the Verizon charger, using the built-in cable, works fine.

[Q] Samsung Gio will not charge using 5Volt power pack

I've used a Philips 5V power pack for my old Galaxy S i9000 (RIP).
It was able to recharge the I9000 3x from the power-pack.
Now I have a Galaxy Gio and this device will not charge from any usb port that is not a USB charger or PC-USB bus.
Can anyone explain this behavior?
(Btw, I've now build my own power pack that delivers 5V / 3A @2500mA/H.
Great for tablets and it outputs 12V also)

Problem Solved:
The Gio needs both data wires to have a voltage. Either 0V or 5V are OK, leave them "floating" then the Gio will not charge.
The i9000 obviously does not require these wires to have a voltage present.
I cant open the Philips power pack to short the 0Volt terminal to the data connections, but my self build power pack works now.
I guess I need to open a microUSB cable and shorten the wires there.
Now where's my duct-tape.......
Case closed

Thx for info`s sure somebody will need this since our battery is so low when we use it extensive !

Strangly I have the same problem with one white GIO from my daughter, but the other black GIO from my son hasn't got this problem.
I can charge the black one with the powerpack and unmodified usb-cable.
The white doesn't charge using this cable and powerpack, it only charges when the cable is attached to the PC or with the original maincharger.
So maybe it's a fault in the telephone.
I'm not gone return the phone as I can solve it by charging it the regular way and if it's not solvable with firmware I will create a cable (or solder something in the phone itself)

some additional notes, both phones are rooted and both phones work with usb on pc (so I can activate usb mode).
i just found another usb charger cable and now it works.

Answer: it's following the spec
I had exactly the same experience: we had one Gio in the household that worked fine charging from any USB charging port. We bought a second, and it would work only with the supplied adapter or a real (on a computer) USB port.
A little digging found this in the Wikipedia entry for USB: "Battery Charging Specification of 2007 defines new types of USB ports, e.g., charging ports. ..."
It goes on to say that a dumb charging port is supposed to have the data lines ("D+" and "D-") shorted together. So I tried this. I took an extra USB extender cable, stripped the outer shielding, cut the data wires (the green and white ones), shorted them together on the device (female) side, and tried it with the new Gio. It worked. Problem solved.
If device manufacturers are taking this spec seriously, then someone needs to start making these adapters for all the old charging ports that don't have the data lines shorted.

Do I need a new USB cable or is there an issue with my phone?

I just got the Galaxy S 4 the other day. It didn't come with a USB cable so I used an old HTC micro-USB cable. Even though the cable worked with my HTC phone, it doesn't exactly work with my Galaxy S 4. I have to move the cable in a certain way to get it to charge or connect, otherwise it doesn't work.
I was able to charge my phone using a micro-USB charger for a bluetooth device (trickle charge, took 12 hours to charge), but obviously this isn't ideal. So is there something wrong with my phone, or just my cable? And what type of micro-USB cable should I get that might work?

It doesnt come with usb ??
Charger works as USB too.
Htc cable doesnt work on samsung phone. Motorola does.

It isn't your usb cable. You need a charge that output 2A at 5V to charge the S4 at decent speed. Computer's USB or typical 5V USB chargers will not do.

Just FYI when I use an older usb cable other than the samsung one, my charging time increases. So using the right USB cable matters. I use an app called Galaxy Charging Current Lite to determine my charging amp with other cables and other wall and car chargers. Very useful app. When using the samsung usb cable with the wall adapter I get 1900 and I can see the battery percentage go up faster. Using an older usb cable with the samsung wall adapter I get about 460 and battery percent goes up slowly. Try the app out and see what you get.

First thing I'd be doing is complain to T-mobile or Samsung. Both GS4s I've received (one on launch, one from insurance) came with the USB cable and charger ready to go.
Next, you need 2A @ 5V, but ya need the right power brick to supply that.
and most likely using older/newer/non-Sammy cables and charge time increasing is because the cables use a smaller gauge wire (like 28 or 30 AWG IIRC) rather than say, 24 or 20 AWG (keep in mind that the smaller the number the bigger the conductor, and larger numbers have smaller conductors). Even with the right power brick, the USB cord still matters; I remember on my Nexus 7 that unless you used its cable charging was either sluggish or non-existant. (FYI the Nexus 7 cable should work with the GS4, I use it for file transfers o my computer and when I did all my rooting.)
also I personally use the battery monitor widget on my Nexus 7 to monitor voltage/current input/output. I may consider putting it on my GS4.

USB Charging Port Malfunctioning

My USB charging port is acting up recently. It's very finicky.
Just last few days, I cannot get "Fast Charging". It just shows regular cable charging.
I've tried:
(1) Firmware Factory Reset
(2) Tried different USB cable aside from the OEM
(3) Tried different wall adapter aside from the OEM
(4) Making sure USB cable is pushed all the way in.
(5) Tried using different wall outlets
I have had this phone for a little over a month.
Anyone else having this charging issue, and found a resolution?

Is your device stock still? If so, you may want to send it back to the OEM now so you don't have the same problem later when out of warranty.

Just for kicks though, have you tried turning the phone off to charge it, letting it fully charge and then let it run all the way down? Is the prong inside your phone still in good condition? I've noticed that the micro USB port on this thing is a bit harder to plug in than the one on my Note 4. Seems more susceptible to getting damaged than the older ones for some reason.
You may also want to see if it has these problems while using a wireless charger. That will help you diagnose the port.

Thank you. I called T-Mobile, and requested a warranty exchange after conveying to them my predicament.
I will get a replacement overnighted.
it's really odd how the Quick Charge/Fast Charging stopped working. I hope it's not a widespread issue.
On a side note, wireless charging works as normal.

It's not your charge port , I had the same issue...try another cable and it will work. It's something with the oem cable, try using the "malfunctioning" cable and plug it in really fast and use pressure, that's how I get mine to work, basically line it up in the hole but don't plug in and then go really fast and plug it in hard.

I explored that avenue. I used various cables aside from the OEM to no avail.
I even tried different Quick Charge 2.0 wall adapters as well to no avail.

This is why I bought the wireless fast charger, the first time I plugged in my phone it didn't feel right at different me and my wife had malfunctioning cords on the note 3 and out samsung tablets charging port broke. I also had a s4 cord die in me so I don't trust their cords or charging ports

I have same problem..my phone is acting weird. .says usb connected and disconnect withoit any cable..not fast chargin either ..and is weird cuz i rarely use the usb to charge. ..and my warranty is void

Samsung needs to have more quality control on it's charging port.
First month, I had the phone, the charging port malfunctioned. I was able to ask T-Mobile for a warranty exchange, and got a replacement.
My replacement recently is also sporadically experiencing the same malfunction. Errrrrr.

Happens with mine when I use the original supplied charger. I have other quick chargers and they always work. So far, my issue is just with samsung charger.
Sent from my SM-G928T using Tapatalk

I have had this problem as well. It seems to me that the supplied cable gets worn out. I have used what I consider to be higher quality ones from other HTC phones and have had no issues.

It's a wide spread issue especially with the s6 edge plus. Mine has been doing it too. Nothing worst than plugging it in and seeing "cable charging" with a ridiculous about of time estimated until full. It's the cable!!! I bought some heavy duty cables a while back... Use it with the supplied charger from my s6 edge + and the note 4 and it's been working every time. That oem cable is a piece of garbage. When you trouble shooted with another cable.... It probably wasn't one capable of carrying the 9v for fast charging. Rarely is it the charger.... It's always the current running through the cable.

I have the exact same problem

Battery Charging

My Samsung GalaxyS3 will only charge via Laptop usb port, If I plug in the wall charger it dis-charges instead of charging.
I googled the problem and it seems to be unique to the S3, but did not find and reason or solution for the problem.
anyone have any idea why this has happened and what can be done to resolve the problem.
there was one suggestion that the usb plug might have dust and is not making a clean connection but that makes no sense

Have you tried different USB cables and chargers?

I had the same issue when I recently went on holiday. I took with me a non-Samsung wall charger with four USB sockets, and some oddball USB cables to charge all my devices.
My S3 was not charging over night. I discovered that the non-Samsung wall charger and the thin USB cable were not providing enough current to charge my phone.
As an experiment, I installed Ampere from Playstore on another Android phone, (it would not work on my S3), and I used it to test all 11 of my wall chargers and 5 cables and I was surprised to find some wall chargers would supply 780mA, while others only 380mA. Similarly, some USB cables would only pass 440mA where as a thicker one would pass 780mA.
The moral of the story is that the Samsung S3 is quite fussy on which wall chargers and cables it will charge from.
The best suggestion is to get a Samsung wall charger for a tablet, and the thickest USB cable you can find.

thank you
