I was watching the Mavericks vs Thunder game using the watch ESPN app and my nexus battery was at about 93%
I watch since halftime to the end of the game and I was plugged in to a car charger the whole time and when the game ended about 1 1/2 hrs later the battery had dropped to 53%. Can't understand it. Hope someone here can explain this to me.
Phone is galaxy nexus, obviously, the battery is the 2100 OEM battery from Verizon store, charger is a belkin dual outlet 1amp micro car charger with the cable that came with a Droid charge.
Thanks in advance ladies and gentlemen, I did look and search, didn't fins anything covering this specific issue.

5V right? that's not a huge draw at all on your battery, i'm assuming your car was either running or started right up afterwards...you can be certain your phone was getting that full 1A especially if your car was running. if your phone showed charging and your phone will normally charge from your car like that then you shouldve been in good shape. despite what you may think, i actually am trying to present relevant info lol but ummm other than that? i would definitely try a multimeter (.....if you have one.....) cuz that would show you exactly what you're getting in/out. usb pinouts should be somewhere on the internet. other than that, try doing the same thing (except for maybe a shorter time period if preferred) on a wall charger which should be more reliable and compare results. i've had devices that burn power faster than they receive them....but the good ole gnex? im not so sure. (engineer here).
I just recently join big red and coming from sprint with an evo 4g and didnt have this issue with that phone and same charger. I'm definitely going to try it with home charger to see if its the charger.
Extra info, the vehicle was powered on before I plugged in the charger, in case it matters any.
Thanks to all the reply thus far.

I find that under heavy usage, only the plug in wall charger gives enough juice to keep it increasing... and even that can go flat or decrease if you are really pushing it... also the way the battery stats are displayed can be flaky too... jumps in the level of charge and quick drops... hard to tell how accurate the reading is.
I hear you. That's crazy, basically the phone draws more power that the charger can provide. I would think the charger should be fine since its 1 amp just like the home charger.

Check in settings - status if it says charging (ac) or charging (usb) when plugged in you car.
If it says charging (usb) the charge amps are limited to 500mA.

The phone can use more power than a car charger can supply. This is commonly posted all over. Check your car charger, its likely a 0.5 amp. Buy a 1 amp or higher.

Your problem is the charger, 1 amp is the sum of the two outlets, hence you're only giving your phone 500mA max. When charging at that low of a rate, you'll drain the battery when doing anything power intensive on the phone. Your only remedies for this is to get a car charger that's capable of putting out 1 amp or more on a single line. What I personally did was get the Griffin Powerjolt dual charger for $8 on Amazon, opened it up, and soldered the center data pins on each port together.

I though that the griffin powerjolt dual outlet charger would dish out 1amp on a single port if the 2nd port was not being used. Interesting, I can see your point. Would you happen to have a picture of, or remember which are the two that need to be bridge inside to make it a full 1amp output?
Thanks in advance.

Okay, I tried what you said and I got weird results. I used the awkward griffin powerjolt dual outlet car charger. I tried using two different cables, one was from my girl's Droid charge and when I plugged it in and check the status it said usb charging, then I plugged in a cable that came with a i go green adapter that I had purchased at an airport and the phone said ac charging. Unless the cable that came with the Droid charge can only pass 500mamp, I'm puzzle.
Both were plugged in at same time and also both cables were tried by themselves in each outlet of the griffin charger by themselves.
Interesting huh. I will keep testing and see what gives, last resort I get a more powerful car charger. Will keep you guys posted, thanks to everyone that contributed and pitch in thus far.

Got an update on this issue. I streamed another 45 mins to 1 hr of ESPN using watch ESPN app and the results are even more interesting. I was using the wall charger that came with the Droid charge and the USB cable that came with the I go green wall adapter that I have purchased at an airport a while back. Here is what happened, when I started streaming the battery was at 94% and I plugged in phone to charger and under settings/about/status it showed AC charging. After 45 mins to 1 hr of streaming the phone was extremely Hot towards the center of the back and below the cam lenses and led light. Also the battery had dropped to 93% and the phone status showed not charging, even though the battery icon on home screen next to clock shows the lightning symbol inside the battery like is charging.
I don't understand what is happening. Grrrrrr. This is using a wall a charger for a droid charge. Now of to trying it with the OEM charger and cable.

The battery can stop charging if it gets too hot (safety measure).

Exactly, in the driver i think the overheat is set to 140F. Also when your charger showed as usb it only gets 509mA and when showing ac it gets the full 1 amp. So just pay attention next time and see if it drains when showing ac.
My car charger is a 1.3 amp and always shows as ac and never drains while charging.

I though about that but then I was wondering, shouldn't the wall charger provide enough power to run everything in there while charging the battery or even without the battery in the phone. Like shouldn't the battery hold the charge that it already has when I started streaming as long as the charger is 1amp?
I would not care if when I stream the phone battery would just hold its charge at what it has at the moment even if it does not charge while streaming. Hopefully that is clear to understand.
To all the fellow galaxy nexus owners out there, maybe you all can test on your phones and see if you get same results as me. Download watch espn and stream the channel for 30 mins, notice what is your battery level before you start streaming, of course plug the phone to a car charger or wall charger and see if battery remains the same, drops charge, or gain charge at the end of 30 mins, or maybe an hour. I am not asking you to watch it for the 30 mins or 1 hour, just let it run and see what happen, if you can of course. only reason why I ask for watch espn is because it is the app that I have been using to stream nba games for the last few days.
Another thing since I am already here with this streaming issue, I have an original SlingBox, the cheapest of the cheapest when they first came out, just coax and that is it. I would like to know if I pay the $29.99 for the app from the market when i switch roms on my galaxy nexus would I lose the app? I have already unlocked and rooted my galaxy nexus and lets say I buy the app and I am running cm9 when I purchase it, if I change to gummy rom or back to a stock rom while still rooted would I have to re-buy the app ?
Thanks in advance for all the input.

No I haven't try that. I am currently testing out roms like a mad man trying to find the best for my liking. Question for ya, As far as I know that is kernel dependent right? Like the kernel has to support it, if so which kernels do support it and what would be good underclocking settings ?
I get similar results while using navigation and pandora at the same time, the phone uses more juice than the car charger can provide.
Ironically I plugged in the oem charger and oem cable from the galaxy nexus box and open it (didn't really wanyed to do that) and streamed 30 mins of espn on watch espn and battery was at 70% when I started after 30 mins streaming it had actually climb to 78%. Confused yet everyone? What gives?
Sent from my PC36100 using xda premium
Not all that odd. Using my Fascinate charger (0.7 amp) I get noticeably slower charge times than the OEM charger (1 amp). I don't use my phone much while I'm charging so I can't provide any feedback for that.
What is the Droid Charge charger rated at?
Does anyone have issues where they are using their phone (just for simple tasks) and noticed your battery is draining significantly? Like right now, I'm typing and my battery just went down another percentage point while posing this.

charging off USB or the wall? USB or car chargers often can't keep up with the drain of LTE phones if you're using them at all.
I'm on AC right now. I have a power strip that sits at the foot of my bed that provides my devices juice.

At which battery level % did this occur?
I'd say if it happens between the 100% to 95% range, its normal, as I have seen that with other phones too.
If it happens at any other percentage, maybe you're charger adapter is not supplying enough power, but that should not be an issue with the stock charger that came in the box.
Have you checked that it's actually charging at AC rate ? I was surprised to find that the charger for my Palm Pre 2 was charging @ USB, I swapped the cable for the one for my TouchPad (same charger) and it changed to AC charging. I'll try different cable and charger combinations when I get time.
Install "Battery Monitor Widget" and monitor the charging rate under mA.
I use the plug that came with the phone a usb to the ac adaptor. I install the app will see tonight when i charge. Also an other point when i charge at night arround 10 pm 5% in the morning wake up at 6 am my phone is charge at 95 to 97% so not fully charge plug all night

It says it's charging USB, not AC.
What does Settings -> Battery say when plugged in, AC or USB ?
Ok for some reason the adaptor that came with the phone when I charge say usb but when I use same adaptor and an other usb cable a blackberry one its say AC. What the...?

Install BetterBattery to figure out what apps are being hung up (partial wakelocks) and re-install them. This drastically increased my battery life!
Also, the screen on wastes the most battery. Try dimming your brightness
Get a 1A charger.

Its the cable. Some USB cables have the data wires shorted or missing altogether and these USB cables are known as charging cables. All they can do is charge the phone. In AC mode. Bought a USB charging cable on amazon for 7 bucks now my car charger charges in AC mode.

I'm looking for recommendations for a car charging cable that will keep the phone charged with the screen on and Bluetooth and GPS running. I have tried both a no name branded and a Samsung OEM car charging cable, and in both cases the phone discharges, not as much with the Samsung but it is still not really usable for long distance navigation.
What do you all recommend for car charging that will stand up to screen/Bluetooth/GPS use?

Look on Amazon for Griffin charger,make sure the output is at least 1000mha, i have the dual usb port one and it works perfectly well, though charging may be a bit slow on navigation + bluetooth music the same time.

I'm using simple 1mA micro car charger and my phone keeps charging (slowly but surely) with bt and satnav on (sygic aura). The trick I'm using is a Voltage Control CPU profile (underclocked to 1.2mHz and slightly undervolted) while I'm running satnav for hours. It's more than enough for that purpose.
EDIT: There are 2mA micro USB chargers now available. I'm sure they should pack a punch enough to charge anything no matter what ur running on ur phone:

I used psp charger.. 1.2mah
I've just had a pretty long drive to take my son to the zoo.
I usually don't charge my phone in the car but because I only had 50% battery left I plugged in the car charger while I used Google navigation...
I had the charger plugged in the entire way and when I got there the battery had dropped by around 15%, so basically the navigation was killing the battery quicker than the car charger could charge it up.
Is that normal??? My screen brightness was on around 60%
Thanks for replies

Well, yes its normal because most likely your car charger is a USB car charger, which charges slower than an AC charger. If you had a custom kernel, and had fast USB charge, then this wouldn't be a problem because it would charge fast enough.

Sorry to sound dumb but i dont quite know what you mean there.
Its a straight charger from the ciggerette lighter to the micro USB port. It doesnt convert from the cig charger to a usb/micro usb cable

Well, it means its charging with USB power (Which is about 500 mah.) and sometimes it can't keep up with the phone using power and charging it at the same time. However, if you get a custom kernel with a "Fast USB Charging" option you can make it charge just as fast as an AC wall charger. Therefore, solving your problem with the dropping battery while charging.

Hello everybody,
I have recently bought the Griffin Dual USB car charger.
I use quite often a GPS navigator when I am driving, so I wanted to buy a car charger which was powerful enough to sustain gps and 3g data plus a little extra juice to charge my phone battery. I found this charger on the internet and the specifications say it's got an output of 1A which should be more than enough for my needs. However, I was quite surprised when I realised that the battery still goes down really slowly when I use the gps app.
I've had a look online and apparently most car chargers are not recognised by your phone as a proper charger. For this reason, they provide only 500mA. You can double check this by having a look at 'settings > about device > Status > Battery status'. If it says 'Charging (USB)', it provides 500mA. Instead, if it says 'Charging (AC)', it provides more (so called fast charging). Well, my phone says Charging (AC). But it's still not enough apparently
Do you guys know any app or anything I can do to test how much the charger is actually providing?
As you can imagine, this is quite annoying.
Thanks
i'm in the same boat as you but a different dual USB Charger
It's suppose to output 2.1A + 1A or something along those lines and it does charge last generation iPad and an iPad Mini at the same time without an issue.
When I plug a Galaxy Nexus in it charges as a USB BUT when I plug the Galaxy S3 it charges as AC but a 2 hour trip only got my phone battery up to 47% which is way way too slow and that is without GPS
The AC charger that came with my phone only outputs 1A but it charges my phone in 2.5 hours from dead flat to full
My car charger is the same. 2.1A port for tablets and stuff. 1A port for everything else. I have noticed that if I plug my s3 in the 2.1A port, it charges slightly faster. However, it's not even close to my 1A wall charger.

Hi, if you are looking for a best usb car charger for your device then i have a option for you. Please check my profile and fo to the link in my bio.. Thank you
I recall back with my old phone (Virgin Mobile LG Optimus V), the lead devs teamed up and made a flashable patch that allowed you to toggle fast charging on and off, basically telling the phone whether it should consider the power source a USB or Wall charger and it worked good. Maybe we can get some people to team up and build that for the S3?
