Nexus 7 very slow to charge?

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).

Defective S3 died 2 days after i bought it!!

Hey Guys,
I have been following this thread since a while and finally took the plunge with the S3.
it was a blue s3 and i loved it.
All stock, not rooted nothing..
So i was downloading my games and apps the first day all went well
the second night, i bought NOVA 3, and put it for charge while downloading the 1.7 gb data for the game over wifi.
i woke up in the morning and the phone is dead, it shows a yellow connect it to kies message.
I dont know what happened?
took it to the service center, they tried re-installing the firmware, but no avail. finally told me they have to replace the motherboard it was fried.
I fought with them and managed to get a replacement unit which im gonna get on monday.
The ordeal aside, i want to know, is it possible this happened because i downloaded too many games(6 actually)
each with about 400 mb data.
can a phone get bricked if i download nova 3's data of 1.6 gb
cause i am going to get all my games again.
so help with the solution!!

probably a 1 off defective unit.

You left it charging overnight right, have you considered a power surge may have fried it?
It's better to wake up early in the morning and put it on charge than to leave it overnight.
Sorry about your loss though.

I don't think the game's could do anything wrong to you while downloading.
Btw while playing games on SIII take care as the Phone's temperature reaches the sky and literally i have to close down the game because the phone becomes too hot.

power surge and over charge are totally different things. over charge protection would not prevent a power surge.

Most probably just a defective unit.
I left my HTC Sensation charging overnight once, and somehow there was an app running continuously and when I woke up the phone was scalding hot to touch. I freaked out and pulled the battery and let the whole thing cool before I booted it up again. Might not be relevant but just goes to show that our phones can take more heat than we think.

Well I have been charging my handsets overnight for at least 6 years now and I have never had a fried nokia, hero, desire, sgs2 or sgs3 ever.
Charging overnight is safe

ASUS TF101 Does not turn on unless plugged in...

So... I cannot turn on my Asus tf101 unless I plug it in to a power source, once the screen lights up I can unplug it immediately and it functions normally when turned on. I bought this device refurbished from best buy a few months back, I dealt with the issue but now am looking to sell it. Any ideas on how to fix this? I have never rooted the device, however I have tried factory resets and cold boots.

Are you holding the pwr button long enough. If so,it sounds like the switch is bad.

I hold the power button for 12 seconds and try it with different variation holding volume keys. It functions fine when the device is powered on.

It could be a bad battery or your charger is only giving enough to power the device on. I would try a new charger first.

But once powered on, it functions flawlessly. The only issue is turning it on.

Do you have the keyboard docking station for it?
Are you on custom ROM or OEM?
What "app killers" are you running?
Some custom ROM's have had similar issues a long while back. maybe yours is getting that issue IF your running custom.
Keyboard dock, if you have it, does it do the same thing for powering on, where it needs to be plugged in to start the screen?
I only ask about the app killers because I had experienced a similar issue about a year ago due to an app killer I had installed. Removed it, and the phone worked fine. Put it back on and it reverted back to having to be plugged in to start the screen.
Have you tried a clean wipe of everything on the tablet? And I do mean CLEAN, no dirty flashes here (keep your pants on bud).
Lastly have you given the charge port a good ole blow out lately? Long bursts aren't really going to do any damage, but I would stick to short quick bursts of compressed gas, again NO VACUUM CLEANERS. They create static and the charge port is quite susceptible to static discharge.
I know your pretty intelligent, but let me put it out there again. DON'T be a fool and use alcohol on your tool.

This post made me laugh. I do not have the keyboard docking station. I have never installed any task killers as I do not believe in them. The tablet has been running the stock ROM the whole time and has never been tampered with.

But you never said if you gave the ole girl a good ole cleaning in the slot.
I would venture to say that you need to send it in to Asus or take it back to Best Buy (if your able to). It sounds like there may be a voltage issue with the digitizer or the inverter.
And NEVER EVER EVER Invert your digits while cleaning out the slot.
You also didn't say if you went deep up in the ole girl and gave her a good rootin.

I'm working with Asus right now and of course there's something wrong with my serial number. Nerve been rooted. Blew it out and that did nothing.

Please keep us posted as I am curious to know how ASUS customer service is to deal with.

Well, I am trying to send my TF to Asus to fix the problem and they are a bit annoying. I have just dealt with HTC before and that was wonderful, but here they have send me 4 emails asking me to wipe, to update and to do everything that I have already done, and after that they have sent me to another web to fill another questionary. With HTC I just had to told them the IMEI and in 4 days I had my phone back

I had similar issue with mine. It was one of the reason I took back to best buy and used the buy back.
I then picked up the Nexus 7.

I had a similar issue, do you use your device often ?
I figured out after a couple of months that each time it showed this behaviour the battery was in fact empty and it was in fact the root of the problem.
My transformer take much longer time to boot when plugged even with a full battery, and when it's empty it doesn't boot at all.
I must plug it, wait for it to be enough charged to boot unplugged, and do so. Then plug it back when started.
Considering that the transformer on stock cannot shut off when plugged to its keyboard (or even to USB ? Or is it just mine ? When I shut it off plugged to the keyboard then close it, it boot on again) When the tablet is left for several days unused the battery will be empty.

Yes I do. But even if the device is fully charged it will still not power on unless plugged in and I don't have the dock.

Do the power and volume buttons work normally once fully booted? I have had similar issues, one was improperly seated power button, the other was a loose ribbon cable way down in the guts of this beast. Also, was this happening the whole time you've had it , or after a firmware update?
Right now I'm dealing with one that the screen won't stay on once I get into ics unless I'm plugged in. I went in and noticed that if the auto brightness wasn't set, it works. So I tweaked the settings in display time off when unplugged and uninstalled some screensaver app, and now it's working fine. It was probably the first thing, even though was already set to one minute. Anyway, just letting people know sometimes it isn't hardware. But the op probably is since he's done factory reset.

Is there something wrong with my orb?

Those jagged lines are from the orb. It doesn't slip or anything and I've tried different outlets but the orb still decides to barely charge. Do I have to RMA this thing?

Try a new orb, or perhaps it is the heat induction coil in the phone, RMA the phone, or the orb see whichever fixes it

Make sure you are using the charger plug that came with the orb. The one that came with the phone doesn't put out enough juice.
Sent from my Nexus 4 using xda app-developers app

I'll try that out. I've got a similar issue. My charger is stuck to the wall next to my bed with command strips. I have a full body screen protector on my phone, and its very grippy so it sticks to the charger all night (I can confirm because the phone is still exactly the same distance from the wall as when I went to sleep). Despite all of this, I still wake up to a phone charged to between 80 and 90 percent. My charge history doesn't look as jagged as his though. It'll just stop charging once its fully charged, leaving me with a phone that has been running on battery for a few hours when I wake up.
I can confirm that my cheap qi charger from eBay set up in my car charges just fine, but it had similar issues when using a cord other than the included one. It would cycle charging every 5 seconds or so.
I'll see what switching back to the included lg cord does.
I'll try the included usb cord.

[ Q ] not turning on

So my nexus had been unplugged and without charge for about 3 weeks or so, I've been very busy at work. I try and connect the tablet so that i can use again and the screen flickers for an instant and nothing happens, I don't see the white icon charging animation and no response after that. It's my tablet done or is there a solution for this. Thanks to anybody that can help.

Ok, I don't really know what exactly the problem is. But I think the battery seems to be dead. because if it is still good, at least it shows the indicator light when it's plugged with charger.. If u have a simple tool to test battery energy maybe u can find out. or maybe try another battery..

Leave it plugged into the charger for a good while and then hold down the power button hard, for about 30 seconds. See if that forces it on.

How long did you leave it plugged in for? It may take a few hours...

Try leaving it plugged in overnight. I once had a laptop battery die on me, had to plug it in for like a week before it would turn on again.

Your device is hibernating to prevent further damaging the battery. Plug it in... boot to bootloader... select power off using the volume keys... the tablet will now charge normally

hi
My problem is solved, I have a friend who had the same problems with the tablet Nexus 7 16GB, the back of the unit opens easily with just a fingernail to open a case as remote and actually the battery plug is not fully inserted into the camera, a little bit of nail to reconnect the cable and now my tablet displays well 100% load.
