Hi all,
Just a quick question, anyone currently using a 2000 / 2100 mah USB car adaptor with their G-Note?
I currently have a 1000 mah adaptor I believe and after a 2.5 / 3 hour journey, whilst charging, connected to the cars bluetooth and using Co-Pilot, I was down to about 20 / 30 % I think at the end of it.
Will the 2000 / 2100 mah USB car adaptors off ebay be ok to use with the G-Note and will it help keep the phone charged when using the phone as a SatNav?
See link to ebay item
Thanks in advance.
A DC power supply shouldn't be measured in mAh... Maybe they meant 2100 milliamperes? 2100 milliamps would be 2.1 amps which is the more amperage than my HP Touchpad charger (2 amps) which should be more than enough.
I don't know how much I would trust an ebay seller that can't even get the terms correctly, but if it's a 2.1 amp charger it should be fine.
Cool, thanks for the heads up PickleHead, I just thought that mAh was the rate of amp flow per hour and didn't realise it was specific for discharge rate of batteries. I'll have another look around.
Just had a look on the back of the USB mains plug for the Note and my Dell Streak and they both have OUTPUT @ 1.0A which is 1 amp right? But a 2.1 amp USB car adaptor should still be fine right? What about 3.1 or even 4.2 amp ones....or are they way too much for the Note?
I've also discovered today what a thirsty little beast the Note is while running satnav. I have a 1 amp car charger with the centre pins shorted together to force the phone to go into "AC Charging" mode, which it does perfectly well. However, over a 20 mile, 30 minute journey I was seeing the battery drop by about 1% per mile (every 90 seconds) whilst charging. That was with CoPilot Live Premium. On the way back I switched to Navfree, with pretty much the same result. I even have CoPilot set to dim the display in between turning announcements. On my old phone that make the difference between a solidly increasing charge and one that struggles to keep up. On the Note it was losing charge even with that feature enabled.
I'm going to need to be finding an alternate charger for the car, so recommendations would be welcome. I can't see a 2 Amp charger being a problem. The Note should take as much as it needs/wants, so long as the charger lets it have the juice it demands.
I would go for the official dock, except I'm told that it won't accommodate the Note whilst protected by a gel skin/case, so the official dock is a non starter for me.

Griffin PowerJolt Micro for iPad.
Output: 5 volts DC at 2.1 amps
Output power: 10 watts
http://store.griffintechnology.com/ipad/original-ipad/powerjolt-micro-ipad
My Griffen Powerjolt charges the battery while Google navigation is running.
It's possible Google nav is less of a power drain than Navfree. I'll have to try it.

I am using the original samsung galaxy tab charger which is rated at 2amps, it works fine with igo, but while using pandora, blurtooth a2dp and igo, the phone charges slowly...
Sent from my GT-N7000 using XDA App
I hav always used a 2A car adaptor as even the Nexus One was a thirst beast as it played the audio over bluetooth to the car dock that had its own speaker.
It works fine with Navigation/Navfree/Waze and the phone charges rather than discharges slowly with the lower power adaptors. The Official Samsung Car Dock comes with a power adaptor that is only rated at 1Amp.
The adaptor I use was intended for an iPad which needs at least 2A. Some adaptors have ratings that should be taken with a pinch of salt. If you can find one rated for an iPad (the type that plugs into the cigar socket and has a USB socket on it rather than an integral iPad connector) then you can't go wrong.
For those asking, I got my Samsung Car Dock from Handtec (in the UK) at: http://www.handtec.co.uk/product.php/5881/samsung-galaxy-note-official-vehicle-dock-kit-
I have the micro usb power cable from the original htc Nexus One car dock. I believe that this provides a 2 amp charging current, and my note charges, albeit slowly while using the phone as a sat nav with google maps
On a similar note about charging (which seems appropriate here), I have the original Galaxy Tab which doesn't allow charging over USB with the standard cable. However I bought an adapter which allows the Tab to charge from a USB port but you can't use it for data, I'm wondering if it's ok to use the same adapter with the Note so it charges quicker off a USB port?
Thanks for the link to the car dock, that looks pretty good

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.

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?
For the past 2 years on my old Desire I was using a homebrew in car charger I put together myself that would happily provide 1A, but my new One X seems a little more power hungry than that and when in car mode it seems to discharge slowly even though it's still plugged in.
Can anybody recommend anything suited for the One X's huge power drain (homebrew or off the shelf, I don't mind) other than HTC's expensive official one? I was looking at the Belkin ones floating about but they still only provide 1A.
Thanks, Dave.
i bought the official ATT universal charger when i got my GS II in Oct and it should work with the One X. also, i think some car docks/mounts are active and have their own chargers, so you might not want both.
I'm using the official HTC Dual USB charger. Does the job nicely. and looks pretty good too. I just wish it was in white to match my One X

I have the same issue as OP. Changed my 800 mah for a 1A but battery is still draining =(
Same problem here... 2x1A HTC Charger... Is there anyboby who tried Belkin 2A mini charger?... I am bit scared, because in my battery monitor history Ive never seen more than + 600mAh... Even when off on home charger... It seems to me, that phone woudlnt allow quick charging... :-(

I had my phone connected to:
Car Bluetooth,
Google Maps on screen,
Screen On,
Poweramp Playing in background via speaker, and
Phone connected to the official HTC Dual USB Car Charger.
No power issues whatsoever. I had it connected and charging for about 10 minutes.
I kind of solved this problem by setting ballanced power consumption policy in my Sygic mobile navigation and lower brightness setting. But still I am unable tu charge my phone while using WAZE (navigation and lot of HSDPA data trafic)...but for now its ok..most important for me is charging during navigation by sygic....
In the end problem is still there and should be solved...I think that its really not ok to charge battery only by 600mA while other phones are able to take 1000mA usually delivered by all chargers..
I just posted about this issue here:
http://forum.xda-developers.com/showthread.php?t=1633245
it's not a problem of charging current, but of the phone battery overheating - it will just stop charging until it cools down (and if there's navi running it won't cool down, ever). I even tried a 2A charger - it will charge happily, but once I start Waze or Sygic it gets hot and starts to discharge again.
I think this is bad design because it should be able to run off the charger without battery in this case, but what it does is charge+discharge battery at the same time... either that or it just starts sipping from the charger when hot because it doesn't care if it's charging or just running from the charger....
Anyway, it has to be fixed.
same problem for me, but with some exception.
Im using Belkin mini car charger with 1A output. in car im turn on only GPS + 3g network. brightness set to 25%.
and with all of this settings battery slowly drain.
Also ive should say that battery not overheated through charging, but after 1% drained, phone says that "consumption is more that charger can give"...
Right now i think about other usb cable, not using original yet, may be inside it wire diameter too small to fit 1A.....
In fact i changed cable too... And it seems thats everything running ok even with waze on
And problem wasnt really overheating related since I have my car holder in front of air-condition grid... Its always under 30°C Best place for quadcore beast btw
I just use the data cable plugged into the USB adapter.
Keeps it topped nicely.
So not perfectly OK... I was driving long way again yesterday... With Sygic on, and my battery stuck at 71% didnt go down on charger, but didnt rise too.. In fact I started my trip at 80% Well it did the job in fact, but after 3hrs of driving it should be full as any other smartphone... :-\
There us something bad with charging policy in OneXs system... :-\

that's because it is using GPS (huge power hog), the screen is on (even bigger power hog) and then the CPU doing the calculations and rendering of the graphics, even with my desire hd it doesn't rise much when using sat nav. its a fact of life. the power consumed by the device is more than the charger can provide.
people have even reported that the mains charger isn't charging it quick enough whilst gaming for instance. (which doesn't surprise me)
Than it is fail of HTC... In fact my LGO2X (in most cases much worst than HTC) Handled it nicelly. HTC doesnt use potencial of charger. It takes only 600mA (top) while charger can deliver 1000mA.... And LG was able to use it....
I modified tiny generic usb car charger (5VDC 1A), so it allows faster charging. When opened up, D+ and D- pins were fed with some amount of electricity to allow iDevice charging, but I simply cut away traces leading to those pins and soldered them together. Phone reports "Charging (AC)". It really is standard method, but "surprisingly" Apple refused to follow standards and generic chargers do not work.
Hi,
i´m not really sure if this question is in the right place here.
After getting my HOX to replace my DHD i would like to know if i can use the DHD Car Charger (original HTC) for the HOX, too?
Thx...
Check out Avantek on Amazon. 2 out of its 5 ports are providing 2.4A, enough to charge your One X at full speed. An awesome product at an awesome price.

Hi Dave,
I have read your post and i refer you to Amazon web services. You will definitely find there best charger for your devices which is compatible with your car.
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.

So I'm struggling to figure out a good car charging setup. I commute an hour each way to work and in the winter I can put quite a load on my phone between listening to a locally stored audio book over BT, and running a nav/traffic app (waze) that sucks data and GPS.
That said I've tested all different combos including running no apps and just letting the phone charge. I can NOT seem to get this thing to charge at higher range than standard USB ~500mah. I've tried a 2.1A charger and a 6A charger....yes I know power doesn't "push" but wanted try something with some higher amperage. I've tried multiple cables including stock. I tested several cables on the stock wall charger and all but one I had pulled close to 1.8A rating, at the very least they all showed around 1000mAh charge rate.
I ordered the "Kopi cable" a 20awg cable touted to support 2A charging. Plugged it in to my mpow 6A charger and through the hour of charging today still never broke the variable range of 500mAh. I am using the Battery Monitor Widget app for the readings. Weather it is accurate or not nothing I've tried with different cables seems to get me the charging rate I need/want.
Whenever I check the charging status in android settings it pretty much always says AC charging mode. One of the cables I had I tried shorting the data pins and it made no difference.
I don't know if it matters but I have the sprint variant.
Any suggestions?
Okay so no one is here with me...
The company of the current charger I'm using sent me another one for free but I'm still convinced the phone is charging to its full potential. Some thoughts/questions:
1. Does the G3 charge at different rates *up to* the 1.8 amps it can accept? I've read phones will slow down when they top off but are there other variances at play?
2. Is there an app known to be accurate for monitoring the charge rate, specifically ma/a being drawn while charging? -I know there are a lot of generic answers to this and apps that claim to do this but I am looking for specific compatibility with the G3. The last app I used was battery monitor widget. If that app is accurate, even with a cable(Kopi cable) rated for 2 amps and using a 6 amp car charger (mpow) I never see more than ~500-600mA and often less.
3. Could heat play a factor in charge rate? On bad weather days I am running a navigation app and streaming an audiobook over bluetooth...wifi radio off. My phone is in an otterbox case and has felt *somewhat* warm after my hour commute running nav and BT audio, screen on the whole way. **On otherwise decent days I am just streaming BT audiobook, no nav, screen off. Phone has never felt warm that way but charge rate doesn't seem to improve.
I'm willing to try a different charger if it will help, but I want to know the phone will pull the full amount that it can. OR, I just need some education on how this device charges. I understand that we don't benefit from the fast charge capability that I read our hardware has.
Thanks to anyone willing to take the time to reply.
