For some reason it won't charge in the car. At home fine. But when plugged in the CIG lighter it won't. It shows the icon in the battery as charging and I have the nexus set with lux auto brightness to be full brightness when charging which it fully illuminates. But if I check battery under settings it states not charging. I've used 2 different cables ( which work on the PC) and 2 different plugs in the light but neither seem to work. One of the states 5v at 1 amp the other has not writing or sticker. What could be the reason for not charging? Running vanir now and was on job sourcery and neither one charges..

I've had some cheap cig lighter chargers 'lie' about their effective output - charging at 0.5amp (standard usb) instead of 1amp or better (wall charger). In which case the charger won't keep up with usage if you're on full brightness and will discharge even though it's getting 0.5amp of charge. Theoretically that may improve by using fast charge setting in your kernel but I've not tried that, just switched to another charger which does output the full 1amp.
Try setting your phone to autobright on charger and then see if the battery says usb charging.
If not maybe the lighter socket in your car is borked.
Well I decided to buy a new plug in for the lighter. Rayova, year I'm cheap. Haha but it worked. Weird 2 of my others worked before but just quit

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..

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.
Is there an app or widget that will display the charging current that is charging the battery? I have a car charger that is supposedly 1A but it seems to charge much more slowly than my 1A home charger and would like to compare them more directly.
Thanks.
Had the same issue here .. looking in to my account and check my posts the answer is there ... shipped from us to UK in a week in my case and I can see huge difference ....

If you want you can see which charging method your phone is using. Settings>battery. If it says charging(usb) the most you are drawing is .5 amps. If it says chargin(AC) then you can pull up to an amp. If you are getting usb charging from a car charger, you don't have the data pins shorted. if you short the data pins, it tells the phone that your charger is a 1a wall charger.
It did say USB. I cut open the cable I was using and shorted the white and green together. Now it says AC. Let's see if it can keep up with BT streaming and navigating.
Thanks.
Unfortunately there's no way to see charging current on this phone like many HTC phones have. But you want it to say ac not USB else its only pulling half the current its capable of.
Worked like a charm. I turned the brightness up, streamed music over BT, and left navigation on during my commute this morning. The battery actually charged instead of drained. Good stuff.
Glad I could help
Great info. Been wondering about this myself. Thanks!
Hello guys
I have a cheap USB charger I got on eBay.
I use my phone as a dash board cam (with the screen on) and the battery decharges faster than the charger can charge it.
Will it be possible for me to find a charger that will "keep up"
Thanks a lot in advance!
it could be either the usb cable if it's not stock or damaged but it very well may be the charger, look for a little bit higher end charger (as in not the cheapest one you can find) and it should work
The specs in the item description says 500-700 mA output at 5VDC. Not only is that low output current, but most list a minimum spec, not a range. You can probably assume 500 mA output for that one, which is not enough. The battery will discharge at a higher rate than that charger can provide.
Anyway, look for one that is rated for 1 Amp (or 1000 mA) output at 5 volts. This should be sufficient. I still use my HTC 1A charger that came with my Nexus One car dock for that reason.

Samsung phones seem to have 2 charging profiles, usb gives you around 450mah and ac gives you around 650mah.
650mah still isn't enough when doing nav/bluetooth streaming, until samsung starts using a full amp for charging you will never have a charger that will keep up.
motorola fast charger
you can use this one:
Search for "Motorola Vehicle Power Adapter micro-USB Rapid Rate Charger" on Amazon
I have been using this for quite a while now on Nexus 7, its just awesome. It has an output of 950+mah which would be enough for Nexus 7.

I used this Griffin-Powerjolt. Found it at walmart, and took it apart and soldered the two middle pins. But found my info here on XDA, but cant seam to find the thread. And I can play games, stream music, etc, and my charger keeps up and charges fine. But this post sums up your question.
Also I'm on AOKP JB and when I was on there ICS roms they have the charging mod so even when I had a cheap-o 500mah charger it saw it as an AC charger and charged at AC charge speed. I think also Cyanogenmod has implemented this also, but im not sure.
+1 for the Motorola charger recommended earlier. It puts out 950ma so the phone will read charging via 'AC' rather than 'USB'. Charges quick and will be able to keep up with BT and GPS navigation. Here is a direct link:
http://www.amazon.com/Motorola-Vehi...Charger/dp/tech-data/B000S5Q9CA/ref=de_a_smtd
I've been using it with all of my Android devices and works very well. Great quality as well. Highly recommend!
I use the 2A Amazon branded charger. You'll want to set it in fast charge, because the phone thinks it is a usb charger. You can open it and short the pins, if you want.

Actual current draw (aka...how fast your phone charges) is not determined by the charger but rather by the phone itself. The ratings on the chargers is what they are capable of, but will be dependent on the device. People would be frying devices all the time by using one device with anothers charging cable that has a totally different output if it was determined by the charger alone.

x3 on this charger. Have used it for the last couple of Android phones as well. Work fantastically with my Nexus streaming music via bluetooth to my car stereo. Never has a problem keeping up.
I'm using my N1 charger still too. Keeps up with nav, stream music, and max brightness. I don't use BT, but otherwise I always gain quite a bit of charge.

oh in another way, you could install a custom kernel and enable fast charging, works for me though.
I bought 2 of these charging only cables. They work perfect, full "AC" charge through any car charger port.
http://www.amazon.com/gp/product/B007F1DV76/ref=oh_details_o02_s00_i00
Put one in my car and my GFs car.
The problem is a "USB" charger spec doesn't allow for the higher voltage charging under most situations. Any cable that does provide the full "AC" charge is a 'non-USB compliant' charger (or something like that), thus, the cable I listed above doesn't say "USB" charger. That is a very brief explanation.

That works fine but I heard it uses your battery faster.
For some reason my new nexus 7 only works with the oem charger not my Galaxy S4 charger or other chargers. Anyone else have these issues?
Sent from my Nexus 7 using Tapatalk 2
Make sure it's the correct voltage and amperage. The oem charger spits out something like 1.3A. A lot of usb phone chargers output less than 1a

my S4 charger works
S2 charger works also.
As does the S3 and N7 Gen1.
So long as it's 1A or greater it'll work at about the same charge rate (1A = slower, and anything over 1.35A won't charge much faster).
I invested in this a while back...best charger I own....

It didn't work on a charger I had that had a "special" cable that only provided power and ground. When I used a normal USB cable, it worked fine, so it apparently wan't to see something more than just an open connection on the data lines before it will charge.
Its worked on any charger I threw at it including the iPad charger with a HTC cable. Wireless charging also works great with the Nokia one.

Anyone tried using the Apple 12W 2.4 apm charger?
Is it ok to use more powerful charger than the one it ships with?
More capacity charger won't be a "problem" as the device determines how much power to pull. Lesser capacity charges can sometimes overheat if not designed well.
Often devices capable of charging faster will only go into that mode if they detect the charger is capable of doing so. Since the way they determine this is not standardized, sometime high capacity charger charge slowly. This could be caused by something on the charger side, or even the cable being used.
Worse case of using a higher capacity charger is it won't charge at all, but that is pretty rare. Often it will charge, either at a slow or fast rate.
Hello all,
I am trying to figure out which is the fastest charger, wired or wireless for the Nexus 5. To do this, I suggest we gather measurements about the charging speed for the phone charging when it has less than 75% charge.
My results are the following so far:
T-Mobile dual usb wall charger 700-800 mA
this ebay Qi charger [1] 200-300 mA
[1] http://www.ebay.com/itm/Wireless-Qi...l_Phone_PDA_Chargers&var=&hash=item51b121c146
Note that the T-mobile dual USB charger was the power source when using the Qi charger and the same microUSB cable was used in both cases.
Does anybody have a wired or wireless charger that can charge faster?
Also, I am using the Elixir 2 app to measure the mA, is there an alternative that does not require the screen on (I feel that it may affect the measurements)?
The one that outputs more mah will charge faster.

They're both awful outputs u need at least 1000 mA / 1A output. You can damage the battery with underpowered charge rates
Also that eBay link states 1A output in the description

Guys, for the wired chargers, we are not talking about the STATED MAXIMUM OUTPUT here, we are talking about the output IN PRACTICE. Most chargers are rated for instantaneous output (it can output 1A or 2A or whatever is listed on the charger, but only for a millisecond, then the rate will fall off).
Please use the app and let me know what your rates for wired charging are (not that the rates fall off when the device is charged more than 75%, so try to test when the charge is lower than that). I bet the rate you find will be lower than 800mA, but if this is not the case, I am curous on the charger and cable that you use.
As for the wireless charger, I know it is very very bad, am trying to return it.
A poor/cheap usb cable will make a massive difference too. I once had a cable that wouldn't let more than 384mA through it!
Sent from my Nexus 5 using Tapatalk
Exactly! This is why I picked the cable I am using now, but I could not get over 900mA with this combination of cable + charger. The Charger is a T-mobile dual USB 3A charger and in my opinion it is very good.
The stock wired charger is rated for 1.2A and actually charges at just over 1 A. The charging chipset in the phone limits charging to 1.5 A max.
The nexus wireless charger charges at 750 mA max. Bad positioning and cases will reduce wireless charging efficiency though.
http://www.anandtech.com/show/7517/google-nexus-5-review/3
I've noticed that during wireless charging my phone will charge at 500-600mA up until 85-87% and after that it will charge at 300mA to 100%, so make sure when you are testing to test at lower battery capacity. Also, try wireless charging from a USB port of a computer, I've noticed that I got better performance form USB port than from 2A touchpad charger.

Wired charging is always going to be faster than wireless charging. Wireless charging on the Nexus 4 Orb takes about twice as long as charging via the supplied wired charger with the Nexus 5. Technology is going to have to advance quite a bit before wireless charging eclipses wired charging. There is an inherent inefficiency with wireless charging that wired charging does not have.
i bough one of those white, skewed ones off ebay for 10€ shipped and am pretty happy with it!
