Recently I've noticed that my Gnex battery will LOOSE charge when plugged into any power source that isn't the Samsung charger. Weird right? If i plug it into my laptop, car charger, an LG wall charger the battery will drain. It has happened multiple times where i've hit 15% battery life and plugged it into my laptop or car charger and it will loose a 1% about every 2-3 minutes.
I've switched roms with no luck. What is going on?
Its not uncommon for this to happen from a laptop port - especially if the phone is being used while plugged in. The USB output on laptops is likely not very high.
Check the amperage of the alternative chargers you are using. If its too low, they won't be able to keep up. Make sure its the same as what the stock Samsung one puts out. Can't recall its exact specs off the top of my head...
Laptop and car charger are 500mah or less. Your phone is using battery faster that it's recharging. Nothing odd about that.

I'm charging on my laptop with a cable of blackberry and no loss there. Charging with at the wall I'm using only samsung utilities so I can't help you out there..
Despite that I don't understand what that has anything to do with rom's?

so the option to not charge it is not ticked under power settings, and its set to charge via usb from advanced config and still no dice.
tried different usb ports and nothing
the led is orange, says its charging in power options
any thoughts?
Try a diffrent usb cable, some cables do not provide enough power to charge the phone. (guessing maybe they are old 1.1 cabels). But I know I have a few cables around that dont charge my phone and they also will not work with my portable external usb hard drive because they wont provide enough power for it. But they work just fine with my digital camera.
I´ve read somewhere that disabling USB charging is better for the battery life, so I have it disabled.
You've tried different USB ports, but were they on the different computers?
so i've tried different cables, different ports and 2 different PC's and 2 different laptops.
I know its not the cable i'm currently using because i plugged it into one of those A/C to USB adapters and charged fine.
I'm starting to think its my batter,
If you have tbattery installed, do u get values for all the boxes?
All mine except 3 or 4 are 0 :/
Well, you are not the only one having this problem. Mine is brand new. I started setting it up last night and had it hooked to the computer via usb. I installed a few .cabs such as google maps, myphone, and a few tweaks such as tether, disable sent notification, enable all camera modes, and manila start menu unlocker. While it was connected it said it was charging. When I went to bed I turned it off and connected it to another usb cable on another computer which is an a/c hub. I went to turn it on this morning and thought it was strange it was not fully charged. I continued to set it up a bit and take it for a spin. After a while I turned it off again and hooked it to the usb a/c charger again. I just tried turning it on and nothing was happening. I connected it to the usb again and it finally turned on, but I checked the battery level and it was at 0% and turned off. I have it connected to the a/c charger and giving it a little bit to see what will happen. One thing that seems strange is that the battery discharged more while it was off and attached to the usb a/c hub during the afternoon causing it to refuse to turn on at all. Any thoughts?

I think the odds are pretty good it's your battery. The orange light means power is going through the charging circuit, so you obviously have your settings correct.
I'm guessing you're in Austin or near? If you want to try popping my battery in it for a few minutes and see if it charges fine then, PM me and we can set something up.
the same thing is happening with mine. Sometimes it will charge, sometimes it wont. weird thing is that it only started doing this a few days ago... i know nothing has changed ROM wise, so only things i can think now is maybe the actual USB connector on the phone or the battery, but since I am getting a charge via wall chargers im not sure what to think lol
Just an update.
If i have the USB cable plugged in (and car charger to which doesn't charge as well ) after 15 min or so a warning appears saying that the current is too low to charge the device. Either closed unused apps or switch to a/c power.
I've ordered a 1800mah Mugen Power Battery. Gonna see if it resolves the issue, if it does then i'm gonna call at&t and see if they'll swap my battery for me.
I have found as have others here after reading some posts that if the phone is almost dead or battery is very low then it will not charge via the USB anymore. The orange light goes on and it says that its charging but the charging circuit seems to be protecting the phone and not letting the battery charge.
The only solution I have found, and it has only happened twice so far is to plug it into a wall charger and fully charge the battery. It will then charge via USB again and all is good. I normally only charge my phone with usb while connected to Activesync but once in a while you seem to need to top it up with a wall charger.
It is also highly recomended not to run Lithium Ion batteries right out.
How do you know it is not charging?
There is a difference in the wiring from a wall charger and a USB charger. There is a signal line in the wall charger telling it to charge at near 1000ma. In the USB cable that line tells it to limit the charge current to 500ma. That is the limit for current that you should pull from a USB port. If you are using the unit heavily, you may actually need more then the 500ma., those running the battery down possibly.
If the unit is idle, it will still take much longer to charger from USB then off of a wall charger.

If you are asking me, I know it was not charging because I also had the "not enough power to charge message" and the phone went from about 15% when I plugged it in to stone cold dead by the morning. The whole time it was pluged into a computer I have used repeatedly to charge it with. I then put it on a AC charger and it went to full charger in about an hour and a half or so.
I just bought a generic USB wall charger and it's taking much longer to charge than the htc charger that came with my EVO.
I'd like to determine the amps/ma the charger is actually putting out. I don't have a multi-meter, so I am hoping there is a hidden menu or app which will tell me what the phone sees.
Any suggestions?
You can download aLogcat and watch for the current usage, it should post it every so often. It should also say on the charger somewhere too, the stock wall charger is 1000mA
I tried this and found nothing showing charge rate, only the battery percent.
A standard usb wall charger should equal how long it takes to charge if you were plugged into you pc. If it is taking longer than that then you got a super el cheapo charger that puts out less than 500ma (milliamps).
I would be carefull too, cheap usb wall chargers are not know to output clean power and have killed devices. By overvolting/charging them.
I have been doing some testing lately with the htc charger and a pc and have come to the conclusion that the htc wall charger pushing 1 amp (1000ma) charges the battery too fast and doesnt allow for a "strong" charge. Meaning your battery will drain faster. The htc charger is, i believe not meant to be your everyday charger, only a boost charger to get you charged back up quickly.
This is common battery knowledge when it comes to charging... you can charge a battery too fast, and a slower; 500ma "trickle charge" is much cleaner and better for your battery.
Some maybe argue this, and thats ok, these are just my personal findings.

I'm not seeing that info in the log either.
The charger had a weird range of 250-1000ma.
Yeah I think I'll invest in a better charger just to be safe.
Thank you both for your replies.
Not sure if this is an issue, or if its standard. But here is what im facing.
A charge off the wall will get my Tmobile SGS2 to a full charge (from around 15%-20%) with the stock plug and cable in about an hour to an hour and a half. However charging from my laptop or from a car charger im only getting a total increase in battery 15% in an hour. I tried to use the stock cable with the laptop and got about 25% in an hour and a half. I tried to use the stock cable in my car and only got 7% in 45 minutes.
Anyone have any ideas?
When charging from the car or from a laptop, the power is limited to what the cable/charger can supply which might not be sufficient for the SGS2. For the car charger, you can try buying one that supplies more amps, but for the laptop, theres really nothing you can do, as it is limited by the USB cable itself.
Do you mean the USB cable or do you mean the actual plug & internal workings of the laptop? because i have tried several cables. And just also remembered that i tried the stock cable as well with crappy results.
you can buy a 2A charger, and it will charge a lot faster, that's what i use in my car
at home or office, i just use the regular charger, as i always carry extra battery packs
When you plug it into the laptop it only gives out a limited amount of amps unlike the regular charger that came with the phone. The one that came with the phone regulates the charge so that it doesn't overcharge your device or anything. The laptop USB plug is supposed to be meant for peripherals like a mouse and stuff so it doesnt give out that much amps, therefore charging slower than a regular charger.
I use the t-mobile rapid car charger, It can charge this beast in about 45 minutes. It also has a 2nd port for a 2nd device.
Deebo took your bike too?
Really?! I've never seen my charging current go over 700 mA, even with a 2 amp charger.
I'd happily give up some long-term lifetime for faster charging.

They have a home charger too that's a home charger plus car charger in 1. I use them in the cars but they're great for trips cause you have a 2 in 1 charger.
With 3 batteries and a external charger though, I never need a home charger and haven't even put this on a charger yet.
Just as most of the others have said here, the charge is going to be limited to what the source can put out. If you get another charger (2A charger) then it will be able to charger faster but you also want to be careful with using after market chargers there are some that can negatively affect your battery by overcharging which is when the phone gets fully charged but the charger does not ever stop with the flow of power to the device.
Ok Thanks all.
Guess i need a new car charger and something for the office.
Also did some crawling through "Mother of all battery life" thread found some good ideas there for making this thing last longer on the charge its got.
Im having the same problem my fone takes forever to charge...im pluged into the wall using the charger in the box n it took me no joke 7 hours to charge my fone!
Im on it rite now as its plugged i to the wall n im losing power instead of charging...i tested the voltage n its fine ...is tgere anythin i can do?

I, myself, actually haven't used the OEM charger that came with the phone. Although I did notice it is quite small and the phone battery is a 1850mAh (larger than normal) that might affect the charging rate. I am currently using the old HTC charger that came with my Sensation and it charges fully in about 2 hours. If you want a charger that charges your phone in an hour and a half, I recommend going into a T-mobile store and grabbing the Wallcharger they sell. It charges 33% faster than OEM chargers and does not harm your device nor kill your batteries.
You can find it by clicking here
Exactly same problem as OP.
OEM wall charger charges phone to full in couple of hours but laptop USB or car USB is doing at 10% / hour assuming you don't do anything on your phone but just leave it there to be charged. Otherwise you'll be losing battery rather than being charged.

As explained in previous post, this is due to limitations in the laptop USB drive and depending on what car charger you have, the phone might suck up more juice than it is able to provide.
so this is nothing a kernel or any other tweak can fix?

So i gotta buy a new charger!?!

Yes, or if you have like an old microUSB charger from HTC or another Samsung phone (Samsung Vibrant) you can try using those.
the 2A chargers from BlackBerry are the best
So, you guys are seeing the phone draw over 700 mA (when the charger is capable)?
If I use my iPad charger (2A), I still top out at 700 mA, and the ~4 hours that go with it. :/
Even my 1A car charger tops out at 700 mA, that's why I thought it was a hardware issue.

Hi guys
Im having a weird problem with the battery. It seems battery doesnt charge when im using the phone although it says and shows it charging! It just stays at the same battery percentage it doesnt charge or drain! When i turn off the screen it charges the battery just fine. I called o2 UK where i bought the phone, the rep said when i use the phone it consumes more power than it gets. Can this be true?! Do you think its just a software bug or defective hardware or defective battery?

This is true if you're charging from the USB on your computer. USB ports only provide 500mA. The phone seems to use more than this if you are actively using it. I recommend using a wall plug that provides at last 1 Amp (1000ma) to effectively charge the phone.
How about car chargers? Same thing happens when its charging with the car charger..
Sent from my Galaxy Nexus
If I'm not mistaken, any car charger, whether it's rated at .5A, 1A, or 2.1A is only going to provide .5A to your phone using a typical USB cable. The USB cable that came with your phone has +/- lines for power as well as 2 data lines. If you pickup a "charging only USB cable" it has the data lines shorted so that only the power lines are functional. This type of cable would allow you to take advantage of the higher current 1A and 2.1A chargers - I think anyway. I'm still new to Nexus so I haven't confirmed that, but that's the way it worked on my old phone. I did read somewhere that even with a charging only cable someone wasn't able to pull 1A from their car charger so I don't know if that was a unique issue or if the Nexus doesn't behave the same way. My understanding is the amount of current pulled from the charger is dependent on the charger AND the phone. Using a special charging cable tricks the phone into thinking it's on A/C I guess.
Anyone else notice that our Nitro is rather fickle about the power source it receives?
If my battery is completely drained, it MUST be plugged into a higher power source than USB (so far a wall charger that ouputs 750ma works) until it gets an initial charge (usually needs at least a couple of %)...Then it will accept charging from USB (USB provides 500ma).
I can tell when it's in this "state" because it remains dead if I plug it into USB and then if I plug it into a wall charger the touch buttons at the bottom flash for a few times and then the LG logo pops up and finally a charging battery icon comes on. Considering this sequence, this seems like a functionality of the phone. I wonder if this is common, my Nexus One certainly didn't have a higher-initial charge rate requirement when the battery was dead.
I've experienceed the same scenario.

I only have chargers that operate 1.8amps and higher.
As the battery is an issue the higher the amps the faster it will charge

Well I did notice that if it was on usb...and I had bluetooth...gps, and wifi...plus running some apps and stuff...the battery actually continued to drain I think they have the usb thing as a safety measure...for some reason...I think it's odd...but meh
try a usb cable that has 2 jacks plugs to connect to tyhe computer. These cables are often supplied with external hard drives as they they require more power than can be supplied by just one usb connection.
I was also having the problem of my p-930 discharging while plugged into compute usb jack - even when screen off nad only in charge mode. I have since bought a dual plugged usb cable and it charges now. Although I haven't tried it from a completely discharged state.
my spectrum is the same way.. i can charge it with usb.. but it takes about 15-20 minutes to get enough charge to turn on
