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

This! I only charge with a wall adapter now. I had a hard time charging it until someone here recommended this to me.
I just got my S2 5 days ago. All this time I been wondering why it takes around 5 hours to charge from 20% to 100%. At first, I been using my G2X charger, it was rated at the same 5V 1A output so I thought it wouldn't matter. Then I used the included Samsung charger with same LG cable, no difference. Now when using the Samsung cable, it only takes about 2 hours to charge from around 15% to 100%.
Is this just coincidence? Is my phone too new and just needed a few cycles? I'll test again tomorrow, or when my phone reaches below 20% with the LG cable.
There's been known issues with using chargers other than stock..mine gets stuck at 100% until I reboot if I use any charger other than the OEM that came with it.

From my experience you're going to always want to use the charger and cord that came with the phone. I bought my Galaxy S II off the streets and it did not come with the cord, so originally I tried using my OG Droid charger since it's micro USB too but it wouldn't even accept it at all (I'm pretty sure because it was too under-powered for the Galaxy S II (My speculation)). I tried using an older LG micro USB cable too (I think it was even older though) it didn't work either, so now I use my Vizio TAB micro USB cord which seems to work fine.
But also at my work we have a 3rd party micro usb charger too but it's universal, but if I charge my phone on there, not only does it take longer to charge it doesn't hold the battery as long.
So what I've figured out is you're gonna want to use your own charger the phone came with to achieve maximum battery life, also unplug the charger right away when it hits 100%.

Wow lol I post the same thing every second day on some forum or other xD
The usb is special in the sense it has a nice rubber feel and cool plastic iphone style caps on the end..
Its a MICRO-USB male to USB male cable, nothing more, seeing as it is still a standard USB cable it has a max current of 5v (5.25 I do believe..), plugging it into a USB to AC converter over 5v can screw up the device and cable, sscond point.
Standard charger is 5v AC, using a charger below wont cause harm, but using one above can screw up your phone and battery and not ground it properly..
3rd point, keep in mind the mAh on the charger when charging, some (for like bluetooth headsets) are only 500mAh)
mAh is an acronym for ampere an hour, and in short, for chargers measures the current sent to the device at an hourly rate, for batterys (such as lithium ion) measures the actual charge capacity of the cell, using one with a higher mAh then the stock battery (1850mAh) will only charge it quicker and is recommended.
Fourth and final, remember with USB to AC adapters that some only have +5 and ground enabled (2 outer pins), ising the device its meant for on a ac adapter with all 4 pins enabled will make the device try to establish a connection and can again, make it not ground properly. I think ours has the 4 pins enabled though so ignore the last point..
*edit
Lmfao at above few posts (your theories have no basis, allow me to explain)
When you plug your charger in, regardless if its connected or not, its "live"
That being said, the every cellphone (keyword: cell) uses a lithium-ion battery,
That cell has a control board with a chip with a bit of information, some variable, the device has READ access to this board, and collects informagion such as max mAh, current mAh, and min mAh, the device then calculates from that, a percentage,
It then displays that information to the user, the minimum (displays 0-1%), is usually a value around ~100mAh if the cell dies to 0mAh, this can reset the control board and drasticly reduce the batterys expectancy and overall life.
Also, the actual chip on the phone, is simply for, when the battery is full, (current mAh meets max)
Said device drops connection to the cell and resumes on AC, leaving battery fully charged.
Unless you use a charger outside above said specifications, its literally impossible for a charger or file on said device (referring to batterystats n00bs who dont research) to adjust or recalibrate a lithium ion battery.
Hows that for a response I kept it clean

That's exactly my point. Shouldn't all micro USB cables be the same? I been charging all my other smartphones with many different micro USB cables and they all charged normally. Now with this phone, it takes over 5 hours to charge with my LG branded cable, this is with the stock S2 charger. Now with the Stock S2 cable, it charges in about 2 hours.
I'm gonna have to test again with the LG cable, as others reported long charging times within the first few days.
BTW, the current rating on a charger is NOT the hourly rate (ah). Also charging a lithium ion battery at a rate of 1850mah or higher should not be recommended.

For chargers, the higher mAh sends a larger current of the same voltage to the device, charging it faster, lower mAh can and will cjarge slowly.. I'm not sayin go use a 5v 50k mAh charger for the battery and charge it in a split second here.
Wtc! I hit edit! Mod plz merge these...
Charge rate of 1C = the capacity of the battery, in our case, 1C = 1850mah. It is not recommended to charge over 0.7C when it comes to lithium ion batteries. If a charge rate of 1850ma is recommended, then why do all chargers top out at 1A?
I collect high performance flashlights, most of them use lithium ion cells. I know about charging and discharging li-ion otherwise I could lose my hands.
Anyway, the point of this thread was about the stock USB cable vs other cables. The only thing I can think of at the moment is that my LG cable has more resistance than the Samsung cable, which is why it charges slower. Though that's hard to believe is the charging time is more than double.

I've noticed that the charger that comes with the S2 has a special hook on one side and looks distinctly different than other usb micro cables.
Personally i think it's really dumb.. wasn't the point of micro Usb to be uniform across all phones?!
Sounds like a good way for Samsung to make some extra bucks.

Well lately my stock samsung charger has been terrible.
Even when I plug it into the wall it charges so slowly that if im below 15%; it will die
When left alone or charging while off for about 45min it will have up about 2-5%; so there's a major problem here.
But using a different charger and it charges at a faster(normal pace); 5% to 65% in appox 1 hour.

Hi all:
I just did a test on the maximum charging current of the One X using current measurement equipment, and it shows that the One X does not draw above 460mA of current while charging.
With this value, i suspect that the One X limits max charging current at 500mA, which means 3 things:
1) Using any previous generation USB charger (750mA or 850mA or 1A) is good enough. Attempting to use the iPad's charger (rated at 2A) WILL NOT get you faster charging time.
2) When using battery draining applications, the charging current may not be enough for you to both CHARGE and USE the Phone. Thus it might be a better idea to give your One X some dedicated charging time.
3) Some computer USB ports may specify 500mA of output current, but there are many times the available current is less than that. On my USB port, the charging current is only about 300mA at times. So it is better to use a dedicated charger if you have it available. Having that said, however, it is still ok to charge the One X with a USB port at 300mA, just that charging will take longer.
That's all I have to report. Useful information for all.

i tried to use the charger for htc chacha and hd2..
both does not work.. red light will light up but after a while it will go off and the phone does not charge..
Charging my HOX while the phones working hard eventually (after say, 5 mins), causes the charge LED to flash green/red. I've had this twice now, once while playing a 720P HD film, and once when playing Glowball.
Both times the phone was very hot, so i'm not sure if the LED thing was to indicate that the battery was too hot to charge, or that the charger could not supply enough power to charge and power the phone at the same time.

If the charger cannot cope with the discharge from the game, a pop up message actually appears. If it's blinking means it's too hot. Try not to do anything intensive the last 20-30% remaining (meaning at 70-100% battery).

Same here... I am using the Atrix 4G (US) charger, it does not charge the phone. The charger gives output of 850mA. It does charge when plugged into the laptop, but I think it will take very long that way.
*edit for posterity*
after a while (I did it when battery had charged to 20%), I could connect the Moto US charger, and it would show as "AC". It would not want to charge through it when the battery was really low (2%), but it would charge via USB in that case. Weird behavior, IMO.
USB limited to 500. AC limited to 1A.
Sent from my HTC One X using xda premium
If you want maximum speed of charging (AC charging) you need:
1A charger with shorted D+ and D- pins (eg, original HTC charger).
iPad charger probably doesn't have these pins shorted, so in this case phone will see it as USB charging (you can check it in settings->battery) and will limit charging current to 500mA. Also lot of aftermarket car chargers will work only in USB mode despite they are able to supply 1A.
Here you can find some info on USB Charging Ports (shorted D+- pins):
http://en.wikipedia.org/wiki/Universal_Serial_Bus#Charging_ports_and_accessory_charging_adapters
When charger is "USB", it will not draw more than 500mA from the charger, and usually it will not charge at all (because the current draw with screen on is higher than 500mA).
When charger is AC, it seems to draw 1000mA - but this is still too low to charge while phone is doing anything, as it will draw 700mA and charge ~250mA top.
I hope this can be tuned in kernel, because it sucks, I also hope that power source can be AC (and not battery - look in dmesg when charger is connected), because battery gets too hot when under load...

Can you post a potential list of car charger which are working at 1mA according to you?
I've only tested few devices:
Extrememac external battery for iPhone/iPad (max 2A) had pins not shorted - USB charging mode on One X (500mA).
Some cheap car adapters - max 1A (according to spec) - USB charging mode on One X.
To fox this problem you should prepare a USB extension cable or micro-usb cable with shorted D+ and D- pins and it should be recognized as AC adapter. I think that also some old HTC phone chargers might come with shorted pins in cable already, but don't know which...
What about the official HTC car charger?

Yes, that one will charge at the full rate.
There is no list of known good chargers - it's down to luck or a recommendation from someone who found one. You can be sure that any charger advertised as "iPhone, iPad or iPod" compatible will NOT charge your One X at the full rate.
I found one recently in a local petrol station shop. It was £5. I took it apart to have a look and the D+ and D- pins are correctly connected together (via a low value resistor) so it charges at the full rate.
So, I might suggest you look for the cheapest Chinese car charger you can.

Bingo. I also noticed that when I have the screen on at 100% brightness, GPS and Bluetooth on, i.e. in the car, the USB charger cannot even keep up with the battery drain.
On top of that, the battery gets really hot.
I did not have any of these issues with my SGS2, and frankly, I think it's very disappointing. One should at least be able to stay on the same battery level while doing nothing too fancy and on USB inside a car.

There are a lot of factors in the charging current. When you charge, the battery will heat up during the process, especially towards the end of the charging cycle. If you are using your phone at the same time and cause even more heat and charging may slow down to prevent overheating. Also, as mentioned prior, charging slows down as capacity is reached. 100% brightness, GPS, and Bluetooth all on has always walked the fine line of just barely keeping up on my past phones on a 500 mA USB charger. On top of that, this phone is a lot more powerful than an SGS2 and the T3 and big screen produce more heat which may be slowing your charging more.
The problem is a lot of cheap chargers that the phone thinks are USB chargers, not AC chargers, thus causing them to only charge at 500 mA. If you have a proper charger, or a properly modified charger, you should get more like 1A, assuming conditions are right.
In the past I've used Battery Monitor Widget from the Play store to show my charging current on a widget, as well as track and graph battery use, charging current, temperature, etc. Might want to give it a try if you're more interested in charging details.
Im using my htc desire charger and cable (the one that splits in two). It works fine for me but it does take a while to get a full charge. Should i use the charger and cable that came with the phone?
hi. the battery charger that i got with my LG optimu G Pro is ****. its just now that i checked that i have been deceived
its chinese copy and its only 0.2A charger...

Use OEM LG charger with 1.2 output. I am using LG G2 OEM charger and it charges very fast! But not sure it's compatible completely
Sent from my LG E988
If youre tech savy you can make your own,you just need a switchmode 5v regulator (they usually put out up to 3 amps) and you put a resistor across the data pins (i think 100 ohm) and itll charge the phone as fast as it can safely charge. I made my own charger for the car and the phone gets fully charged in about an hour and a half. (With screen on and playing Bluetooth music). Other wise if you buy a charger, get as many amps as you can. Atleast 1.5+ . and to make the phone charge in AC mode if it only says USB you need a resistor across the data pins.
Thats funny... my G Pro came with a 1.8a LG charger, my G2 came with a 1.2a.
Yeah you'll be fine. The "extra" amperage in the charger is available capacity that your phone can draw from, it will regulate itself but that can also depend on the charger and how they pin the USB. Its different than if you have extra volts (like a 10vdc charger which would provide too high of a voltage and damage electronics). I usually charge all my phones at when I get home with my wife's iPad charger super fast. Likewise you can use your LG charger to charge the iPad but will be slower since it has less amp capacity to supply. Part of the reason they provide the bigger charger is to sustain battery level while using the device (It should be large enough that the battery doesn't drain while your using the device while plugged into the charger).
Most computer USB ports typically provide .5a of power and will be your slowest charging option, at best you get a newer laptop with "high capacity" ports and it provides only 1.0a.
I've been using an iPad 1st gen charger with GPro since day one, been working flawlessly for 4 months now. Charges fast.
Hey I'm expierencing a problem charging my phone.
It will charge over USB with AC adapter plugged in.
I used one charger and it worked over AC most of the time...now I'm going through chargers because they're useless
The voltage on my charging port is fine, and the USB port is fine.
What gives? What charger do I need?
Charging over USB takes like 6 hours with my extended battery, which is kind of ridiculous.... At 500amps/USB I'll actually loose charge while using the phone and having AC adapted plugged in
So the problem is it charges over USB when it should be AC
Thanks dudes
Make sure the cable is high quality - a cheap cable may only charge at 5v 300mAh.
The thicker the cable, the better it probably is. You can buy a USB voltage/current meter for a couple of USD: https://www.ebay.co.uk/itm/231817507267
For the stock battery, expect a 90 minute charge time. With fast charging, expect 60 minutes.

LOL @ 90 and 60 main
I can't recall what stock battery is
But with a fast charger my battery takes 3 hours 42 min over AC. It is 6500 mah though
I thought the new one is a faster charging cable.....its thick.
I suspect I might be having a motherboard problem not charger port problem
The problem is it charges over USB
My phone was serviced for power failure before
Even with the cable I had before....it would switch back and forth from AC to USB

Thanks for the tip. Bought another cable
You'd think this general electric (GE) cable I bought before my new one I got now is high quality....its a POS
The one I used before I stepped on the USB tip by accident so that's a no no
Samaubg cable is garbage too
Although it sometimes using USB. It will actually use AC now most of time

If it is charging on 'USB', remove the cable and re-insert it. Then wait a few seconds. I also have this problem.

Seems like wrong cable I'll do this a million times
Right cable less often though it still does it
Sometimes it goes anal and does it for like 2 days
Good old lg. Should become a repair company instead
