I got my Nexus 7 now after a long experience with Android devices, mostly phones, and I think N7 is a pain to charge.
Sometimes when I'm using it plugged in charge, it seams like the force is just enought to avoid discharging, no to charge. Anyone with this kind of experience?

Not enough details.
Don't expect it to charge plugged into your PC.
it is normal that charges slow when connected to the PC via USB, in fact most of 10.1 tablets does not charge at all turned on, there is not enough power, if it's connected to the wall charger then may be something wrong.
I'm using the stock wall charger. I'll observe better and than be back here with more data about charging times. Thanks.

Make sure you use the original charger and USB cable that came with it. My experience is that it charges relatively quick and consistent across multiple units.

Sorry if this sounds amateur, but I was wondering if I would be able to use my cell phone charger with the Nexus 7 without it causing damage. Or is the reverse true too?
The output on the Nexus 7 charger is : 5V - 2A
The output on the One S charger is: 5V - 1A
The input on the Nexus 7 charger is 100mA higher.
Now technically this means if I use the Cell charger the tablet would take longer to charge right?
But what if I use the tablet charger for my cell phone? Would it damage my phone?
I'm only wondering because I don't want to have too many cables cluttering my workspace.
Thanks in advance.

You're right about the charge time. And yes you can use it on your phone. I have a 2A charger for my g2x that's blazing fast.

It charges super slow on my GNex charger. 10% in an hour
you can use the nexus7 on your phone it will work as a rapid charge, i wouldnt make a habit of it...
Don't quote me on this, but using the 2A charger for your phone should work just fine, as it should have an internal limiter that prevents too much current from being passed through the device, damaging it. I have done that before (with a different charger) with success, so it should be just fine. Also, the N7 *should* charge on the 1A charger, just a LOT slower, and may only charge if you turn it off.
Thanks for all the quick responses guys. I just wanted to make sure I don't do any damage to them.

Hello everyone, I have a new nexus 7 and love it, but it seems to take way too long to charge. After a full discharge, my tablet takes more them 24 hours to charge. I have drained my battery twice to the point that my nexus powers off. Then I plug in, some back after more then a nights rest and still not fully charged? Not sure what'd going on, but this does not seem normal....

are you plugging it in a usb or a wall charger? usb will take much longer.
I am using the wall charger adapter and cord which came with the nexus...

try a different outlet or a different charger? to make sure its not the n7 that's having an issue.
Great idea! I should have thought of that, now I feel like a retard....lol

I'm in the same boat. It makes no sense. I've called Google Play support once already because it randomly died at over 30%. This last time I was using it I was at I assume over 20% since the battery level wasn't red and then it made the noise that battery was low and then turned off. What is the proper way to calibrate a battery since there are 90 million different ways if you search Google. I am running stock, rooted 4.1.1 btw. The last person's suggestion and lols following are not uncommon nowadays on xda, we just need some real solutions, thanks.
I feel my Nexus 7 is slow to charge, but it does do so overnight.
When plugged in to the charger and cord provided by google/asus, under Settings/Battery it says it is charging(AC), though once it did say charging (usb).
Would this be a safe idea it terms of the life of the battery down the road? I also bought a 3rd party car charger.

I use chargers from various phones. Have used different phone chargers with all my phones. Never had or noticed any problems. I'm sure you will be fine.

Yes, it's safe. I'm using an old Samsung charger to charge my Nexus. The charger doesn't really matter IMO.

When using chargers that don’t come with the device, the only difference it can possibly cause is the rate of charging (how fast your device charges).
Just take a look at the milliamp rating on your charger. The N4 comes with a charger that outputs at 1400ma. I found that if I charged my N4 with a charger made for SE Arc, it takes forever to charge which isn’t a surprise since that charger outputs 750ma.
Don’t worry about using a higher milliamp charger on a device that’s rated to charge at a lower rate. The device will only draw what it needs. I’m not sure what’s the maximum ma the N4 will charge at, but let’s assume it will charge at 1400ma maximum. Even if you use a 2A charger, it will still charge at 1400ma.
Even I thot its safe and was using my Nexus 7 charger with the Nexus 4 . everything was fine for a few hours. Then suddenly it froze and the screen started getting weird lines on it .I immediately removed the charger and while the device was rebooting I could notice that the screen had a burn in kinda image on it. It slowly faded away later. Haven't used the Nexus 7 charger since and I've never got the same issue again.

I don't think so. Cuz I wasn't even using it. It was just lying there most of the time. I switched on the display and was looking at battery monitor widget to check the charging status and then maybe twitter or something and it just froze. Held down the power button for 10seconds then restarted it.

As a rule of thumb I'd keep then Nexus 4 away from the Nexus 7 charger.

The N7 charger is rated at 2A. I sometimes use it to charge my N4. Most of the time, I use a generic 2A charger. At the office, I use a Samsung 2A charger for my N4. I’ve encountered zero problems.
Truthfully I'm more concerned using a 12v in the car. Any suggestions what I can get?

Anybody else seeing that even if your phone is plugged in it will continue discharging if you are using it?
Sent from my HTC One using xda premium
Isn't this always the case? My understanding is that the phone is always powered by the battery and not the plug. If your using the phone and using more power than the charger is supplying then the phone will discharge accordingly. Could be wrong but that's always how I thought it worked.

What's your battery life like? You may have some issues with software maxing out the CPU.
Anyway, the One X battery can run out when using navigation software and on car charger (maybe 0.5A).

What are you using the phone for when it is discharging? Also, are you using stock AC charger or car charger?
Battery life seems fine, i am basically just browsing the web and watching a few yoitube video's, i am usin a 2A car charger.

Can you please try and replicate the same problem with the stock charger? 2A seems fine but just to be sure..
Yeah i will try when i get home from work.

I ran into that when I was using a under rated charger or just plugged into a USB port. Official chargers (or equivalent) didn't have that problem it was slower if I was constantly using it while charging, but it did it.
Playing games, navigate, heavy tasks - looses percentage.
Browsing,messaging, mailing,etc - The battery charges.

I believe this is correct. Whenever I used my Lumia 920 for gps+music on a cheap car charger, it would always discharge faster than it would charge. This is because 1) 12V-car/usb chargers charge at a slower rate than AC chargers and 2) some cheaper car chargers output even lower than normal USB charging rates.
Shopping for a new mobile/car charging solution for my Asus TF300T (gonna use for GPS.. tethered to my HTC One) and my HTC One, i ended up getting this multi-use charger. Initially, i was going to get this high power charger just for usb (which is the first charger on amazon i've seen to output 18 W / 3.6 A), but wanted a more unified solution that I could plug both my One and TF300t into. Because I'll be using the tablet for GPS+music, I can tuck the phone away charging at a tolerable rate. Oh, a direct 12v car charger to HTC One will charge the fastest if that's what you're looking for.
Recently my wife broke her USB port on her n7, so I decided to just attach some wire to the pogo pins as I know there was a ground and a 5v line. After I installed battery monitor, hers was charging at 1000 to 1300ma. Mine charges at 500-600ma.
Maybe my port is broken too I'm not sure. Can anyone confirm this?

Hi I use the dock to charge my n7. I have noticed a faster charging rate. However i do not know how to measure this

Download battery monitor widget from play store. It will display the MV on the top right of the screen.

I also charge my nexus from a homemade dock at the 1000-1300 mark compared with my usb port. The usb port is so bad that most of the time I see it discharging while in use!!!
I believe this is a hardware fault as mine used to charge great through usb. at one point my usb socket stopped working altogether, I ran a soldering iron over it and it is at least working again, still slow to charge.
I have also been following a thread about this in the google user forums. One person stated that when they changed the usb board charging rates resumed to normal standards. There is a lot of people in that thread suffering from this. Bad show google.
Have you guys confirmed that the n7 charges faster off the pogo pins?

It can charge just as fast off USB I know mine does I think the problem seems to be that the ports are easily damaged and it slows the charge rate

I have been following a thread on google forums about people suffering from poor charging rates. I can confirm that many users in that thread, myself included, have found that charging through pogo pins charges normally, whilst the usb charging takes forever and even discharges with screen on!!

is that with the provided 2 amp charger?
It is with a third party charger as my charger broke, but it was the same with the original.

The 5V oem charger output 2000mA. Any charger 2A should fast charge.
Also the pogo pin can charge on 12V 500ma (which is automobile acc. standart)
See more info on Qualcomm FastCharge Standart
There's a chip that identify the power output available. So a charger 1A charger will be identify by the device, therefore it won't fastcharge.
