Hey all, xda noob here! Just got my Nitro for Christmas and loving it so far (way better than the Backflip I replaced it with).
Having trouble with the battery though. When I'm playing a high-demand game, I lose battery even when I'm plugged into the included wall charger. I know that it's possible for the battery to drain faster than a car charger or usb port can keep up with, but from what I could find, that doesn't usually happen with a wall charger.
Just wanted to know if this is normal, or if it's something with my phone.
Never tried to game while being on the wall charger. I can give it a try tonite to see whether it's happening to me too. What game are you playing btw, just so I can test the same game too.
Kinda funny though, since the wall charger has 1.2amp output, which should be more than enough to power the phone and charge the battery at the same time.
I can confirm this issue as well.
My laptop adapter has USB charging port with 2.0A output, plugged in Nitro would discharge during Google Talk video call + active WiFi tithering (with not much use from connected laptop), although the battery stats say it's charging.
Playing Sentinel 3. I'm rooted, but haven't tried any of the battery optimization suggestions yet. Either way, that's a lot of drain. At one point I also got an overheat warning, and powered off, only to find that the battery was completely drained. Not sure if the issues are related.
Well, now the next on the list...battery drain/overheat issue lol!! I'm trying to defend this phone, but hell, LG really ****ed this phone up hehe.
mine works just fine.

More FUD I see...
USB charging ports are limited to 1.5A as per USB 2.0 specifications. The Nitro HD requires 1.2A to charge. If you have other USB devices connected to the system, you won't get the dedicated 1.5A. This is why your device loses power yet the charge indicator is active.

Wait, this phone overheats too? Jeez, I'm trying to add up all the positives so I can go and grab one, but I'm really hesitant now! lol!

Not sure what other devices you are referring to, I was talking about a wall adapter with one usb port charge only. Since I can't really test how much amperage there is, I can't say if its a fud or not, however we are talking about charge-only port, I see no reason why they should follow usb 2.0 specifications to 100%, and besides there is always gadgets for super quick charge, I'm sure they don't follow such specifications.
But the fact that even with the original wall adapter Nitro can drain battery faster then charging just shows there is something wrong with the picture.
I seem to have an issue that my phone never charges whilst connected via USB to my Macbook Pro. I have also tested on a Windows machine and have the same issue.
I was able to charge my Sensation over USB and I know that one of the ports on the Macbook has a higher output for charging but it makes no difference.
The phone states that it is charging but the percentage charge continues to drop. If I switch the power off it will charge. There doesn't appear to be any big battery drains though. I ran for a day and twelve hours over the weekend and charged at 40 percent.
Has anyone else the same issue?
Btw, I am on stock 4.0.2, rooted but not running anything else that should have any affect

How old is your macbook pro? Or more to the point, do you know if it has USB 3.0 ports? If your higher output ports are just 2.0 (and your computer is describing them as such compared to the older 1.0 spec) then you are stuck at 0.5A (half of wall charger output). USB 3.0 goes up to 0.9A, but I don't know if there are any catches in terms of devices needing to request the bump.
When you say that it charges if you switch the power off, do you mean it only works if you actually power down the phone? As in, leaving it sleeping plugged in, it still won't charge? Keep in mind that actively using the phone with the brightness turned up high could result in overpowering the .5A current in.
Unless you know someone else with a GN you can test you might just want to take it into the store and have them try it there/consider a replacement if it's defective. Also worth exploring if it's just the battery is defunct, if you have access to another one.

Really? Source?
Doing a tad of research it seems some models front (closer to the front) USB port has slightly higher output than the back (closer to the screen) USB port because the back one shares a USB controller with internal components.
It couldn't be noticeable though, they're both simply rated at .5A .

I charge my 4.0.2 stock GSM Nexus off of my MacBookPro almost every night without issues. Using both an HTC cable and the Samsung cable.

MacBooks don't have USB 3.0. Its always been standard USB 2.0 afaik.
I'd also recommend that OP check different cables and computers, or different batteries if possible.
I have the exact issue. If I charge via USB on ANY laptop/computer it takes forever and if I'm using the phone as it's charging it uses more power than being supplied so it loses battery life even though it's plugged in.
I had this problem on my iPad too. It seems they need more power to charge but can still "trickle" charge off of a standard USB port.
My batter was at 10% last night, plugged it in to my laptop and sent some texts and left the display on (dev settings), about 10 min. latter it was at 4%.
I mean to post this last week!
See the screenshot....Status 'Charging' however as you see from the lower part of the screen, it has clearly stopped charging some time ago (about 3 hours earlier!)
It turns out that the CABLE was the issue....I thought all Micro USB cables were created equal, evidently not
Any ideas what the differences are in micro USB cables and how to identify which ones 'work' and which don't? I bought 10 from ebay which all seem not to charge from USB
I've had no problems charging via my pc using Samsung or Motorola cables. It charges slower but it still works.
Hi guys,
I have a simple MHL connector (ie splits into power & hdmi), to hookup the phone to the big screen. It looks pretty decent, but even when connected to mains, (which it must have otherwise hdmi doesnt work), it loses charge while playing video.
I have tried several players (dice / mx).. all play well, but phone cant keep up with charging & playing at same time..
Am doing some tests to see how bad it draws. When I go into system details, phone shows it is charging via mains.. but it appears it cant put out enough current to charge and play..
Would make a LOT of sense to me that the LCD screen (which draws about 70% of the power) actually switched off during playback via HDMI.
anyone know if this is possible or if they can charge & play a video at the same time..
I seem to be losing about 1% battery every 2 mins.
Can someone else test so i can know if It is just a dodgy MHL I have or if they are all like this. Have tried both SD & HD video.. all quite similar results.
be aware
Use the original charger or one with 5v 1a otherwise your phone won't get enough power for example I know a BlackBerry charger has a lower output

This was with the original charger unfortunately.
This is the same issue why I wrote that One X is unusable for in-car navigation. Basicaly what happens when under load (navigation, playing a movie, playing a game) is that battery gets into "Overheat" state (you can see this in OS Monitor for example) and stops charging.
My test for car navigation shows that power is drained by 25%/hour when plugged in and Sygic is running. Battery is in overheat state most of the time. This happens at about 50 deg.C if I remember correctly - this looks a little low so maybe they'll tweak it a little, but it doesn't solve the underlying problem really, just delays it...
So I blame crappy heatsink construction or overral internal design, this should not happen under any circumstances (and my iPhone is a marvellous example that it can be done - it is able to navigate and charge at the same time, and gets into overheat only when car ventilation is turned off and sun is shining on its' black body - my One X is white and overheats no matter what I do).
This will sooner or later be the reason why people will start returning their phones en masse...
Get 2 amps charger from eBay, see if it helps. I do have one, but only use it when I really need a quick charge in very shor time. Not advised to use as primary charger, but for powering both: phone and MHL at the same time, it might just do the trick.

I tried this, doesn't work. The problem is not insufficient current, it's overheating.

2a won't work as the phone is limited to 1a
If the battery temp is 48 or over it goes in to overheat state green and red notification.
If you are rooted you could disable two cores see if that helps.

This same issue came up in the Nexus forums a while back. Evidently, AC charging requires that the USB data lines to be either shorted or have a resistor across them (forget which one). Since MHL is using those USB data lines for video, they cannot be used to signal AC charging capability, so you're stuck with the max USB draw of 500ma. That's way less than the amount of juice you're using, so you end up running the battery down. You should be able to confirm that by noting the charging mode displayed while using MHL.

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.

I believe that charge is 1a shared.
---------------------------------------------------------------
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.

Swiftkey'ed on my CM9 Galaxy Nexus
I'm getting rapid battery drain issues while using MHL adapter. I'm still trouble shooting, but have to experiment more. In the mean time, I was thinking maybe someone may have some suggestions.
I just transition from the HTV Evo 4G. Great phone, but it's showing its age. I have a job with a lot of dead time. With the Evo, and Cyangenmod, I would mirror the phone onto a 16" HDTV and watch Netflix, Hulu, NFL, Crackle, Plex, play games and so forth. I would also WiFi tether so I could use my tablet to do email, web browser, IM and so forth. I had the phone over clocked and used the performance gov. If had the phone connect to a charger, it would actually charge, albeit slowly back up to a fully charge This is with the screen that new shut off while pausing a media, but set to the lowest brightness.
The GN2, nowhere near the performance. If I WiFi tether and stream some media and mirror to the TV via the MHL adapter, I loose around 20% battery.per hour. I have power save on. I use my tablets power adapter with outputs 2.1mah instead of the 1 like the one that comes with GN2. I still have the screen set to lowest brightness.
From the settings menu for battery, the screen takes up the most juice. This is expected. But I also streamed content on phone while charging and it did build up a charge, albeit very slow.
I'm thinking it may be the MHL adapter itselt. I have the have USB charger connected to work. It's possible the phone doesn't put out enough power to work the MHL adapter. I'm not certain, but it's possible the MHL adapter is only doing a trickle charge. I had it plugged in, but phone screen off, and looks like it draining the battery. I want to run a longer test to confirm.
I purchase a cheap MHL from monoprice. I had to get the 11pin to 5pin adapter to use it. I'm not sure it is the MHL or the adapter that may cause issues.
In the mean time, I changed the kernals to Persus. Hoping to get better performance, or higher charging capablities. It's improved slightly, maybe 18% drain per hour. I'm just using CPU Mater, free version. I upped the CPU to 1.8ghz, but the free version does include anything for the battery. I don't really want to spend the $3 on SetCPU because I don't know if there gov has a lot towards the battery charging mods.
Any ideas or suggestions?

A. you are wrong, the charger that comes with our phone is 2 amps.
B. make sure you use the cable that came with the phone as it is rated for 2 amps, other cables will have too much resistance
C. it is normal for the mhl adapter to eat through your battery, maybe not as much as you are saying, but this phone uses the 11 pin mhl adapter which allows for FULL hd unlike older mhls/microhdmi ports so it is bound to murder your battery
D. I don't recommend you wirelessly tethering at the same time, my phone will eat through my battery like crazy with the screen turned off while tethering to play online games... this might be the root of your problem

I think you're right on the cable. I tried it at home, using the charger and cable that came with the phone. Did an hour of Netflix, WiFi tethered the tablet. Battery drain...1%
I'll guess I need to get new USB cables since I like to keep extras in various locations, LOL.
Also, I miss read the chrager. I shouldn't read when I'm too tired. The good news, my tablets 2.1A charger should be only a very low risk of too much power. I was concerned with it, when I thought the charger was 1A
I realize what I'm doing is power drain, but it should be doable is the phone is on a charger. I'm not necessarily expecting it to charge back up, but I figure in the six to seven hours, a reasonable drain on the charger should be maybe 30%. This is only an assumption since I don't know how much the screen drains the battery.

there is no risk of overcharging from amperage, the phone will take what it wants and not use the rest... you could have a 500 amp charger yet our phone would only use the 2 amps it's rated for. The problem comes from voltage if you have to much voltage then you overcharge.
you also fail to realize that the phone takes a lot of juice to convert it's image into a standard hdmi signal, it's the difference between you talking to yourself and you trying to make someone else understand you... the processor has to act as a graphics card, a sound card and its usual processing needs... the epic 4g touch ate just as much power per hour while on mhl yet it was only outputting 16:9 480p
as for getting more cables be careful and ensure they can handle the 2 amp drop

Well, it seemed the biggest culprit was not the cable, but the charger. I actually brought the Samsung charger to work. I was only getting around 2% to 5% battery drain per hour. It was really low.
Unfortunately my ignorence on electricity is showing. I'm not seeing why such a dramatic difference between the Samsung and ASUS (TF700T tablet) chargers. Their readings are similar but not exact:
ASUS: Input: 100-240V 50/60Hz 0.5A, Output: 5V==2A or 15V==1.2A
Samsung: Input 100-240V 50/60Hz 0.35A, Output 5V ==2.0A
As for cables, I'm not sure where I can go to find good USB cables that work as well or better than the one that came with the phone. Usually I just go to monoprice, but that's where I got my other cables.
BlackBerry cables r usually more beefy than others since they are rated for data transfer. whenever flashing through Odin that's what I use never had a problem. assuming it's the same for charging. they usually only run like 5 bucks too

they might be beefy, but still have ****ty materials. it all depends on the impedance of the cable... if you have a multimeter check the resistance on the cables and compare them to the stock
