Looks like my Nexus 7 is faulty.
Arrived with 40% charge, been on charge for a while now with the supplied charger and the battery is at 35%
Suggestions ?
I had this; thought it was dead. I plugged and unplugged it a number of times, both the usb to the wall adapter and the microusb to the N7. I did this quite a lot before it would registering as charging. My device was also off at the time, partly as it did the same as you are reporting and sucked the battery dry. Once I got it charging the first time it has been fine, but it was pretty annoying; I reckon there was some uncleared plastic or similar that was preventing it, but nothing I could see at the time. Hope this helps you
I had this issue yesterday where suddenly the battery no longer went past 11%. Flashed factory image and now all is well.

So my n7 ran out of power I turned it on and my wallpaper had been reset then voltage control started up and the whole tablet went crazy and the screen went solid grey?!?!
Edit: seems to be voltage control when it starts on boot. Anybody else have this problem?

I've just had a funny do with mine.. playing games while plugged in to charge, seems I was using more power than it was drawing tho and the battery went - but when it did, the screen went a scrolling grey (bit like the old loading screens on a ZX Spectrum!) and making a crackly static noise. Plugged the plug to kill it, and I'll give it time to charge properly before turning it back on again
Same here I was using my nexus 7 while it was plugged on my PC and looks like my battery was discharging instead of charging looks like the tablet itself eat more battery then a charge would give x)

For a proper charge it needs 2 amps. Your computer only gives half an amp.
Of course it will discharge if you only supply it with a quarter of the power.
Seems to be that when overclocked it needs battery to work properly!

the exact same thing happened with mine. I was using motorola charger while playing games, and encountered the grey screen with the static noise. I panicked for a sec there!! After all I've only been using it for a day.
Charged it using my HTC charger and turned it back on. I checked the battery monitor widget and found out that my motorola charger delivered very little charge to the device. Googled about it and read somewhere that N7 is quite picky in terms of charger.
They're very picky about chargers. One charger that works really well and is available off the shelf for $25 is the Asus transformer prime charger available as places like office depot, and other retailers, probably staples and best buy.
The power spec of 2 amps required is correct, but even with 2 amp and higher output specs on the charger, many USB chargers with equal or higher specs still will only very slowly trickle charge because the N7 is so finicky about power sources.

First time it happened to me I thought I bricked the thing. I wasnt even using it and when I came back to take it off the charger it the tablet was flipping out (im guessing i had some weird battery drain and a charger problem at the same time).
Shouldn't the tablet shut down before it gets that low on battery? It would've saved me the almost heart attack I had when I saw this happening.

Had my Nexus 7 about a week now, had some system restarts at random times (when not even using the device) which is a bit of a concern, but read it could be the 4.2 update. But as hasn't happened while using so far it's not annoyed me. However charging is becoming a bit annoying. It's taking forever!
I have a battery widget installed and its stats tell the story. Battery is usually fully charge in: 6 hours 59 minutes.
It's plugged into the wall, with the cable and charger it came with, tried using an Apple charger block to see if it was that, no luck. Not tried another Micro USB cable yet, but may do if anyone thinks it could be that?
Also according to the stats it charges 1% every 7 minutes and I put it on charge at 9:45am this morning at 35% and it currently on 66% and it is now 2:55pm. It also says it will finish charging at 7:00pm tonight.
The app/widget is Battery Widget? Reborn! Does this have anything to do with the slow charging?
But this is a bit of a joke to be honest. Is my device faulty?
Mine charged from 1% to full in 2h10m today. Stock charger.

You are using the original 2A charger right? Have you tried with an other USB cable on it (might be broken?)
Also try to monitor your charging without the app, just write down what time you plugged it in at what percent and check it that way. (the app might show wrong readings).
If you have an other 2A charger you can borrow, you can try to eliminate that to. Not sure how long it takes via a regular USB port on the PC.
If it keeps charging that slow, your battery might be defect..
Good luck anyway
I'm unsure what's wrong!!!
My phone has been fine, until it died today. I practice a 1 charge a day rule and I let my battery drain completely before I even think about putting it back on the charger.
Today, my phone died a littler earlier than expected, but that's okay because I was using my iPhone for most of the day. I got home at about 11PM and put my phone on the charger at 11:15PM. Here it is, 2:25AM and my phone only has 30% charge.
I've never noticed it charging this slowly before because I typically put it on the charger before I go to sleep and take it off when I wake up. This doesn't seem normal from ANY phone that I've ever used or troubleshooted in my life.
Why so slow? Is everyone's phone just as slow or should I be concerned?
Edit: I am using the charger that came with my phone in the same wall outlet that I've used since I got the phone. Nothing else is plugged into that outlet, either.
It would seem sensible to try a different charger and power outlet.

Your should be at 100% in that 3 hours. Try using a tablet wall charger.
With my phone, sometimes it charges in a flash, and sometimes it's charging for hours, idk why they do this.

I don't have another charger. All I own is Apple products, unfortunately.
I've done other other outlets throughout the house before posting, but I wouldn't see why the one I'm using is compromised in the slightest. It's charged the phone fine since I've gotten it.

The only Tablet I have is my iPad. I was thinking about just using the A/C adapter, but I was worried that that might mess something up with my luck. LOL.
You can't use the iPhone\iPad chargers as most of them don't comply with the USB charging standard (It will only charge at 500ma, the limit of USB charging).
You said it died quicker than usual as well? Sure nothing is running that drains the battery? Check the battery usage in settings after leaving it unplugged a while and see if you see anything that's using a ridiculous amount of battery.
I've had the same problem. Sometimes I plug mine into a wall charger and it reads Charging (USB) which may be your problem. Other times it reads Charging (AC).

It's been off of the charger for about an an hour and a half and nothing out of the norm is draining the battery. Screen on time is at 40%, but that's because I was reading all of my sports news and stuff from my device.
Interesting thing to note: I'm at 79% on my Nexus 4 after about an hour and a half unplugged and doing regular browsing. I'm at 98% on my 4s with doing just about the same things as I've done on my Nexus 4, and even watching a YouTube video on my 4s. I've also had a great deal of voice calls and texts this morning to my iPhone. They were neck and neck when I first got my N4 on December 10th. Now, it's dying faster. The only difference is that I've installed Spotify on my Nexus 4 since then... Which isn't running.

It was reading USB last night! I thought that was normal, lmao... Thinking it meant "there is a USB cable charging it and not wireless charging."
Hm... The plot thickens, I guess.
Yeah it sometimes reads USB but if you unplug then plug it back in, it will change to AC. Not sure how to fix it but that's your problem right there.
Question: are you stock, rooted stock, or different ROM?

Or more like charging issues?
I've got this phone in December and I'm pretty satisfied with it. The only thing that kinda annoys me is the fact that my phone often won't charge properly and I'm not sure if it's because of the charger (the one that comes with the Nexus) or the battery.
When I charge it, it says that it's charging. Just like it should be. The problem is though, that it's not really charging. A few seconds later it says that it's discharging, not even a second later it's charging again, then discharging and it goes like that all the time. I'm almost sure that this harms my battery a lot. When I let it charge over night, most of the time the battery level is under 100% (50-60% are more likely) and that is kinda frustrating when going to work.
So I want to know: does anybody have the same issue or something similar? Or do I just have a faulty device/charger? This issue has been plaguing me for around a month now.

Have you tried it with another charger? I always use a universal charger and that works fine. If that doesn`t help it is probably a hardware issue and you`ll need to get it fixed.
AW: N4 massive battery issues
Unfortunately I don't have any charger with an output of 1.2A. All of them are under 1.2A and most are broken anyway (also chargers from my last phone, LG Optimus 2X). Seems like I'm just not that lucky when it comes to chargers.. I'll try to find one though. Thanks for the reply.

Just to test it, use your computer usb. It isn't full power but it is enough to see if there is an issue. Maybe a new cable?
AW: N4 massive battery issues
Not sure if this is related to my computer now but when I plug it in it says charging and as soon as the MTP notification pops up it doesn't charge anymore.
Should I try to fully discharge my battery and then recharge it?

Okay so I somehow fixed it.. most likely temporarily but it seems like the issue is the cable. I pretty much "straightened" the cable with my fingers (was applying pressure to the cable and then went slowly downwards) and that apparently worked o_o..
Now it's been charging for 15 minutes without disconnecting once. I hope it'll remain like that..

my nexus7 will not charge until it has completely drained....
I am aware of the current battery problems, but mine is a bit different....
Even after going to bootloader and choosing power off my nexus will sit on charge (wall) overnight and be dead in the morning, even though it was at 30% when plugged in....
The only way to charge it seems to be off my laptop. but even then it takes over a full day to charge.
If i hook up to laptop while runing it basically only slows down the drain but still doesn't charge up....
this is very frustrating, and i'm at my ropes end
would dowgrading to an older rom take care of this issue?

No solution, I'm afraid, I'm chiming in to say that I have also been having problems since the same time. For two days, I have been trying different combos of chargers, cables, and outlets, to see if other equipment is the problem. But all of it works fine with my Nexus 4. Mostly, I am experiencing that the unit says "charging" but the battery level is going down instead of up. I managed to get a full charge overnight by using an external battery that I got just for this type of emergency backup. After use, it is back down. This morning, third cable I tried finally seems to be working, for now. In 40 minutes it went from 63% to 65%. I am somewhat relieved but this situation is not normal.
I'm going to start reading through the forum to try some suggestions. I wasn't paying attention to updates. Has this problem been triggered by a recent update?
I understand some suggestions call for letting the battery discharge entirely. It seems that won't be hard to do. I can leave it plugged in and, as happened with most of the cables I tried, the battery level will go down to zero pretty fast. I'm really annoyed, but very happy right now that I splurged on an external battery.
Have you tried a new charging block... That would more that likely be your culprit.

Check your port for bent pins.

I used three different chargers plus the external battery. Two of the chargers have two inputs (i.e., for Apple and non-Apple products). I have five different charging cords, longest is 6 ft and the others much shorter (two are from Monoprice), and one retractable I usually use in the car. I tried every combination I could think of between chargers, cables, input ports, and several different electrical outlets at two locations.
All the various combos functioned fine with my Nexus 4, the other device I have with me. None of them worked with the Nexus 7. All showed as "charging", but they weren't. In some cases, the numbers were going down quote rapidly. Goes without saying, when you're charging, it shouldn't go from 64% to 59%.
The thing that finally worked - with no hiccups - was the external battery. Since everything worked on the Nexus 4, it's quite apparent the problem is the Nexus 7.
Having said that, by this morning, things inexplicably changed for the better. With the device at around 70%, I connected one of the chargers and it functioned normally. Battery filled up within the normal timeframe. I was using it intermittently while charging, as I often do.
I'm glad it's working and very glad I have the external battery that can fill up both the Nexus 4 and Nexus 7 in a pinch. But I still think there's something wrong with the Nexus 7, and I'm not knowledgeable enough to dare try some of the more technical suggestions. Just the term "shorting out the pins" is enough to warn me that I'm not expert enugh to try anything like that. For now it works, I hope it lasts like that until perhaps I can understand the issues a little better.
I'm having the exact same issue as you guys and it has me stumped. On some days it'll work, others it wouldn't. At first I thought I could fix it by rebooting but last night mine just drained all the way down overnight while charging from around 50% and this morning I wasn't having much luck getting it charged using the 2 stock Nexus 7 wall chargers that I have. I'll try using an external that I got recently and hopefully that'll solve the issue for now at least.
Edit: Some people have had luck reversing the polarity on their charging block. I'll give that a go and report back whether it worked for me or not.
Edit/Update: Yup, flipped my brick around so that the big end sticks off the left side and it's at 32% now from 0% after 2.5 hours. You guys might have some luck with this too.
Nexus 7 fails to charge
We have two Nexus 7 in the house, one 11 months the other 6 months old.* The older one stopped charging just before our holiday last month so we took the other. It stopped charging while we were away.* Fortunately my wife had here Samsung Ace [mains] phone charger with her. This worked every time.*
Once home I checked the two Nexus 7 mains units and 2 Nexus 7 usb cables. No combination would charge either Nexus 7.* The Samsung mains charger would always charge both Nexus 7.
Solution:* Suspicious, I ordered an Asus Nexus 7 cradle while we were away. Any combination of Nexus 7 mains unit and usb cable charges both Nexus 7s on the cradle.
Conclusion: The USB socket on the Nexus 7 cannot take repeated insertion and removal of the cable.
Hope this may help somebody.
Yea I had the EXACT same story as you. I had for got to take my nexus 7 charger on holiday but I had my Samsung galaxy ace (s5830i) charger so I used that. when I came back and pluged In my charger It said that It wasn't charging so I used my brothers nexus 7 charger but still no good. It said that my brothers nexus 7 was charging but not mine and than I figured out what I had damaged... My nexus 7 charging port. I had proved this by comparing the the 2 charges and they where very different... Luckly It was still under warranty so I took it to (I cant tell you that). I looked all innocent and pretended I was new to this stuff and they then tried to charge it but no use so they replaced it with a new one but now I know not to put different chargers in my new nexus 7 and that goes to people out there as well
