My device charges very slowly if the display is off. If the display is on it does not charge at all.
I've installed the Samsung drivers from the website. Is anyone else able to charge their device via USB? I need to know if I should exchange mine.

I was able to charge my sgs2 yesterday at work through the usb port. It might be the phone, or maybe the usb port you are trying to use doesn't have enough juice to charge the phone? have you tried another usb port on the computer?
usb will always charge really slow compared to an wall outlet
Yes I have tried multiple ports, computers, and cables. Oh well, I guess I'll live with it.

USB supplies max 500mA. Is probably half what the wall charger is giving you. Nexus S is only 750. My guess gsII is 1000 (1A). iPad charger is 2A.
Edit: no a higher power one than the stock charger won't charge the phone faster in a noticeable way. Charging circuits in remotely modern phones limit current to that safe max. If they don't you're probably risking damaging your phone.

I understand that the USB on the computer is weaker. I was surprised to see that when the phone was connected to the computer, screen on, and streaming music that my battery was actually reducing slowly. I would expect the opposite and this behavior seems abnormal.
Sent from my SGH-T989 using XDA App
that's exactly the reason why in car i use the 2A charger (2000 mAh), and in house i use 1000 mAh wall charger
if i leave it at the computer USB charging, i've to keep it iddle for it to charge after like... 4+ hours
that's usually what i do at the work place, so i keep the battery topped up, for when i need to jump back in the road
as long as you have WiFi on, or 3G/4G on, or if the CPU is in high activity, you'll never see the charge ever reaching the battery.
i always keep a spare wall charger at the office as well for times when i need a quick charge
Thanks for the input everyone! I'm glad it's not defective cause I love this phone!

My issue is a little different but decided against another thread. My phone will not charge with any other cable. Has to be pluged in to oem cable. I left it all night on my old phones charger and woke up with it almost dead. Plugged into oem it just charges super slow. Should i take it back?

Does the other micro USB cable work with other devices? If not, might be a defective cable.
On a side note, who prefers to charge via 500mah vs 1A? I have been charging my phone since day one using my printer, as well as my old Iphone. My battery performance is great! +24 hours on a single charge with moderate browsing 50/50 wifi and 4g. I typically enable the "power save" feature with minimal brightness and 15 sec screen timeout.

[Q] Charging problem
I have an issue that has popped up today. When charging through PC, the phone (not battery) is getting pretty hot and losing charge. I'm not sure what could be causing it. I stopped all extra processes and turned off the screen. This is not occurring when the phone is off.
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)

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!
Sent from my Galaxy Nexus
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.

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.
To charge a phone on USB cable from PC takes me around 9hrs, from car charger around 4.5. Also, USB is not able to supply enough power whilst I`m browsing internet, its still discharging.
220v charger charges fine and quick.
Is it just mine handset or this is how it is?
Thats normal. PC USB ports can only provide 500 mA of current. The wall charger provides 1000 mA.

Your iPhone is the equivalent of a Corolla. Mass consumed, easy on gas and not very capable.
Yeah this is the same for me. On my old phone i could charge it while using it, but it would charge slowly. I guess the Galaxy Nexus is just power hungry.
your experience is normal and I thought it was strange at first as well coming from a 3gS iPhone. My phone barely charges from my work computer.
That's weird. I can use my Gnex while charging with no problem. Just did it last night. It may charge a little slower, but still charges none the less.

The current iPhone is not for me, but it's definitely capable. Honestly, there aren't too many Android phones that are better all around phones. Luckily, I own one of them.
Hi guys!
TL;DR at the end.
After posting on here a while back, asking for advice about the Epic 4G touch, I decided to buy the phone.
However, i'm having a problem. One of my biggestt decisions to get this phone was that, as far as I could find online, the phone was equally good at 4G as my old EVO and capable of doing WiFi hotspot without too much trouble.
Last night I got my new phone, set it up, rooted it, installed CWM, and then set myself up with the Blazer ROM, which I really like.
Blazer comes with the "sprint hotspot hack" so the builtin Hotspot app works fine.
Yay!
Except, it uses battery even faster than my EVO Did. with my old EVO, I could hook up the phone to my laptop via USB to charge it and use hotspot at the same time. It would still maintain 100% (roughly) charge even while broadcasting the wireless network, as long as it was plugged in.
This is not the case with 4G touch.. It steadily loses battery while using the HotSpot, even while charging! this is unacceptable as I use my hotspot for hours at a time.
What can I do? Is this an issue with the blazer ROM? Is there something I can do to make it charge faster? ?Use less battery? Would using a 3rd party hotspot app (like WiFi tether) consume less battery?
TL;DR
Hotspot uses too much battery even while plugged in and charging. What do?
-Saph
Is there no way you could you the AC charger do you have to use the USB? Also try placing you phone down screen first and taking the back cover off to allow the access heat to escape.
Have you tried USB tethering instead? Dunno if that is unlocked in blazer or not..
If bringing the adapter with me will make the difference, then I will start doing so
I tried out using the Wireless Tether app instead of the built in sprint hotspot, and I noticed that the Wireless tether app uses less power (so it charges while on USB instead of losing power) and also generates less heat... However it wont let me use any security protocols. If I do so, then the tether has errors and fails.
So it seems like i'ms tuck between a rock and a hard place..
Barnacles, I can't rely on the USB tether. I need it to be WiFi. T be honest, my 4G is my primary internet, even at home, so I need it to be wireless capable for myself and my boyfriend to use at the same time
Also wait a few days for the rom to settle in so you can see the full battery savings effects. also use setcpu or tegrak and Underclock/undervolt during this time and you should be fine

Make sure the power rating is 1A, 5 Watts. Some are 500 or 700 mAh (even though they may be Samsung branded), those are insufficient for our phones.
LOL what kind of boyfriend leeches his internet off his girlfriend's 4G tether setup?
Tell him to get you some legit internet service
Thanks, phatman! i'll make sure i get the proper voltage.
@LordJummy: We live separately, but when we're together we both play games. So I need to have it on WiFi so we both have access. I can't afford to pay another bill on top of what I already pay, and sprint has never *****ed about my tethering, sooo.. im gonna keep using what works.
Usually the output amperage from a computer usb port is .5 amps. My suggestion is get a usb charger (for car or house) that is for the apple ipad. Those are high amperage output chargers rated at 2.1 amps. I used a standard charger while using the phone and noticed that the charger couldn't keep up with the demand for power for charging and using the phone at the same time. I got a charger for an ipad and now it can charge and I can run the phone at the same time no problem. Here's some links.

Getting ready for a cross-US trip next month and just noticed something with my GNex vs my 4S.
On my 4S attached to my 1A cig lighter charger from Belkin, I am able to charge the batter while navigating with GPS and screen on. This is using actual navigation, not the built in stuff for iOS5 and earlier.
I simply assumed the same would be true of my GNex but I noticed today that if I am using Google Nav with the screen on and connected to the same 1A Belkin charger, I lose about 1% every 20 minutes or so from my brief testing.
It doesn't appear to be overheating as the charging lights and symbols on the phone continue to show charging and the phone isn't all that hot. It's also not been using for any really long trips yet so it hasn't had a lot of time to get super hot if it's going to.
Just curious if this is common for the GNex while running only GPS with screen on.
I did some searching but the other complaints I found involved people also streaming music while using GPS nav.
People have reported this, and it makes sense if you're on a 1A charger, especially if you have a Verizon model connected to LTE. This is similar to the complaints that people can't charge on a 500mA USB 2.0 port while tethering LTE.
I personally don't notice it draining when I'm listening to music (stored, not streaming) and Navigating, although it's usually on trips of 45min at most and I have a GSM model. My battery seems to just hold or barely charge. I'm not sure of the exact output of my charger though. It's an AT&T branded accessory with a main cable, and a second full-sized USB port.

Yup, normal for the LTE models. It was actually one of the biggest complaints when it was initially released. Turn off LTE while using navigation.

the next nexus needs an IR blaster. think of all the diabolical fun!
I haven't tried it on my Galaxy Nexus but his was certainly the same on my older Nexus S.
Verizon Nexus here and I have no problems in this regard.
I usually stream Pandora while using Google Maps Navigation and have a little speaker plugged into the USB port on the charger and it still charges the phone's battery.
LTE is on as well. Never turn it off.
Using the "MicroUSB Dual Vehicle Power Charger w/USB port" charger from Verizon.
Use Battery Monitor Widget and see if it says "AC" or "USB" when it's charging. You want to see AC or it won't be pulling enough juice. If you see USB, try a different cable. You can also force fast charging with the proper kernel. I use Franco, which has an option for it. That alone didn't seem to help, but I bought the Fast Charge app, which seemed to do the trick.
I just went through this myself on a 2 week motorcycle trip. I used a 3rd party GPS app the entire time, screen on, and streaming music. I had LTE on and I believe as long as my screen was set at around 65% or less I never had an issue.
So, yes it can be done. You just need to figure out the right setup. I did some research before my trip and from what I read, not all USB cables are the same. On my bike I had a low-profile dual USB charger.
90% is the USB cable.
It happens on my Galaxy Tab 10.1 with the default Samsung USB charger, when I connect it to my laptop. Then, if I browse on Internet with the tablet, my battery drains faster than charge, even if connected to the laptop with the USB.
The key is to discover if there is the USB or calbe problem with A output.

Sure enough, it was going to USB on the car charger. I unplugged the phone and went in the Franco Kernal Config and enabled USB Fast Charge. Plugged it back in and it recognized as AC and true enough, it charged my phone while using Nav so YAY!
Only problem I'm having is that on any reboot, even though it is still checked in the Franco Config, I have to uncheck USB Fast Charge and recheck it before plugging it into the charger for it to not go back to USB.

Not sure why it's needed, but after I bought this:
https://play.google.com/store/apps/details?id=com.incredicontrol.fastchargewidget
I only needed to toggle the widget to fast once, and then my problems went away. Worth a few pennies prior to the trip...
I boggles the mind why this is set up this way in stock form..
why??
BTW to the OP, I just switched from a 4S, also had a 1amp charger that did the same as yours, that same charger on the Nexus won't charge the battery with GSM model. It drains about 3-5 % over around an hour commute, more if the sun is directly on it and it gets hot.
Still, why does it seem to force a .5 amp charge when the capability is there for more??
This is annoying that you have to grab up a custom kernel to do this. With JB I'm quite happy with the way the phone is stock and non-rooted but I guess I'm going to have to root and throw on a custom kernel after all.
If you like to solder cables, you can mod your car charger to register as a AC charger.
Give me a second, I'll find the thread.
