My Nexus 7 battery takes forever to charge. And this is even when I use my stock cable to the wall charger. I know it takes around 3-4 hours to charge it from dead to full but for some reason mine is only HALFWAY full at the 4 hour mark and I usually have to leave it on the charger the whole night/day for it to be fully charged.
I have no other defects on this product except for this one. And I never dropped it or anything and I'm currently running 4.1.2.
Please help. I know I can't be the only one with this problem.
Definitely use the oem charger (2 Amp compared to 500-850 ma for most) and the supplied USB-3 cable. It will charge faster. After the long initial charge up to 100% mine has been charging pretty well. If I'm down around 10% it can take up to 4 hrs to charge, but the battery is huge compared to most phones. It sounds like something isn't working normally for you. Have you tried turning it off, then charging?
Yes sorry I was unclear in the original post. I'm using everything stock when I charge my Nexus 7. I don't use any other cable. And yes I completely turn it off when I'm charging but yet it still charges horribly slow.
I would test another comparable charger just to make sure it's not the charger or cable itself.
There is a lot of threads that talk about the charger and the possible ones you can & can't use (Nexus 7 is picky). I use a HP Touchpad USB plug and a cable. It does the job well :good:

I use the HP touchpad charger, Playbook charger and KFHD charger. All three of those get the job done fast.
With those three, I don't even need to use the N7 charger lol

Do you keep it on while you're charging it? If so that will definitely make it take longer to charge since it's using power.
Nope.

I keep mine on, so I can check the % on screen. And long as you don't use it while it's charging, it won't take longer.
Trust me I keep everything that I charge off so that it can charge faster and not be using any power while charging. It seems no one else has gone through this from this thread though. It sucks that I have to get a new charger when the stock charger should be still working fine and perfectly.
As far as i have read the informations on / in box. It said to use the OEM charger only. I didn't really measure time when charging, but it always took maybe 2-3 hours max to charge the device completely.
Try blowing out your micro port with compressed air, had this on my galaxy2

Hi,
I just bought a Nexus 7 and noticed that it has a different charger than the Android smartphones I have, e.g. Nexus S and Galaxy Nexus. However, the connection is still the same.
My question is, is it safe to use a smartphone charger with my Nexus 7, just to have less stuff lying around? Is it safe to use the 7's charger with my smartphone? Will I break my devices if I do it?
Thanks!
Perfectly safe. The Nexus charger puts out slightly more current than most phones, worst case it will charge them slightly faster, just as a phone charger will be a little shower with the tablet.

You won't break your devices, but it would take an extraordinarily long time to charge your N7 with the phone's charger. Conversely, the phone is not going to charge exponentially faster using the tab's charger. So, all in all, wile it's not ideal, you won't be hurting anything.

So I can just keep my Nexus 7 charger and use it for every other gadget, and put the other chargers into a drawer? That's nice to know, thanks guys.

The phone won't charge any faster using the N7 charger, but the tablet on the phone charger would be significantly slower- to the point that even moderate use while plugged in would result in still draining the battery. Assuming no use while charging, the tablet would require several hours more than normal for a full charge.

I disagree, my galaxy prevail charges twice as fast on my n7 charger than with a standard phone/car charger. However my n7 does take forever on the phone/car charger. Literally like 8hrs+ to reach 100%.

Check the 'mA' or 'A' rating on the charger.. The higher it is, the faster it will charge.
the charger I got bundled with Nexus 7 is outputing 2A (2000mA to be exact), which is quite higher than most phone chargers
(I've got chargers with standard 500mA & with 800mA).
I've been using the Nexus 7 charger for charging my ZTE Blade and nothing seems wrong using it..
A phone's charging circuit will automatically restrict the current to the specs needed by the phone.
PS: 'A' stands for 'Amperes' & 'mA' stands for 'milli Amperes ', both are units of measuring current.
Since the battery life of the phone is quite poor it's only natural that i would like to charge it when i'm on class or with an usb cable when im using my laptop, using other usb chargers/cables, but on the manual says (of course) that we should only use it with the lg charger that comes in the box or an official nexus 4 charger .
It kinda sounds like bullsh*t until i remember what happened with my motorola milestone, sometimes when i used another charger the screen started doing crazy things, like swipping the homescreens by itself , oppening apps, until i charged it for at least a few minutes with the official charger, some months later my digitalizer died, so you can imagine how traumatized i am, but then i think what's the point of trying to make a standard out of microusb chargers if we can only use the official charger? what do you guys think?
I find battery life to be very good.
I have been using an old HTC charger on mine without issue though. I suspect the 'only use LG charger' is to cover themselves in case you kill the device with a cheap and badly made knock off.

AW: We can only use the LG charger?
I have literally problems in draining my battery, running Franco's Kernel and Minco v6.
Anyway, using another charger should be no problem. I used the charger of my Asus Transformer and a mobile charger in my car without issues.

Feel free to use any USB wallcharger you'll find.
I tried some i had laying around (HTC, iPhone 5, iPad) and they all charged without trouble.. :good:
Yeah, I've used a 1A HTC charger with no issue. I accidentally left my lg charger at a friends house and had to use what I had.
the battery life is good, better than s2 with its extended battery, i was wondering about this too as i want to use a sony rx100 at 2amps to charge while im traveling.
on page 168 of the service manual it states the max charging current is set at 900mah, over voltage protection upto 28volts
The current should be controlled by the phone, not the charger. Therefore there shouldn't be a problem with more powerful chargers. The voltage has to be correct, though
The phone certainly regulates the power it takes.
If you are really worried about the chargers just flip them over and read the output ratings. Most of them are exactly the same these days.

I use my GNex charger with no problems.
P.s- the battery life on this device is outstanding, you just need to find the kernel that works well on your device

Any USB charger will work. Note the output current on the charger though, as that will impact how fast it can charge and whether or not you can have the screen on while you charge. The LG charger that comes with the phone is 5v 1.2a, an iPhone charger (at least as of the 4S when I got mine) is 5v 1a and an Amazon Kindle charger is 5v 0.85a. The USB 2.0 spec calls out a max power output of 5v 0.5a.

I'm confused , the lg nexus 4 charger is 5.0v 1.2A and my galaxy nexus charger which i use sometimes with my nexus 4 is 5.0V 1.0A , what does this mean? what's the difference?
My Nexus 4 is on the way so i cant comment on that but my Sony Xperia S acts differently to different USB leads even on the same charge unit. It might charge at 500mAh or 950mAh (on a charger rated at 850mAh), the screen might be fine or it might act erratic and it all depends on the lead plugged in to the charger
I used Samsung/blackberry chargers and they worked. Not sure if they were as efficient though.
I pretty much use anything but the LG charger and have been doing so over a month. So feel free to use any quality charger you like.
I also charge of my Philips Qi pad and off computer USB ports.
As long as it's providing stable power or anything close to it, it's good.
Just be careful with (fake) cheapo chargers. Those might cause issues with the touchscreen going haywire while charging off them. I've also read that about some car chargers, but so far my cheap 2A 2port USB car charger that came of DX is working fine for me.
YMMV of course. But there is no need to stick to just the LG charger.
I've had the Nexus 4 for about 2 months now and it's really the best phone I've ever owned. But switching from an iPhone 4S, I can't help but realize how long charging takes. It's about 2 hours to a complete charge on an iPhone and almost 4 hours on a Nexus 4. I know the Nexus 4 has a battery that's a third bigger, but it shouldn't mean that it will take twice as long to charge.
I still have my iPhone wall plug lying around. Has anyone been brave enough to combine their Nexus 4 USB cable with an iPhone wall plug to see if it would charge faster? Or is there any charger that'll speed up the process (Samsung or HTC)? I haven't tried it yet I know Google and LG advise against using other chargers but I think it's worth a try especially if I need a quick charge before I go somewhere.
Side note: Previously, I did charge my iPhone using a iPad charger connected to a MacBook Pro extension. It would fully charge in about 90 minutes which was 30 minutes quick than usual and I did it often for almost a year without any problems.
Doesn't the iPhone wall charger have a rating of 1 Amp? The N4 charger has a higher rating of 1.2 Amps. Check and see.
Yeah, I've read that somewhere. But like always, numbers don't always reflect world world performance.
My N4's at full charge right now but I might give it a go tonight when it's empty. If anything, I would just expect the N4 to detect it as a USB source instead of an AC source.

It'll charge. That's not an issue. I'm just thinking it won't be any faster.
I've plugged my nexus into an iphone plug every day since I got it back in December (it takes up less space). The phone is fine, however, I wouldn't have a clue is it's faster or slower to load.
How long would you say it takes you to completely charge from 10% battery?
Yeah ive noticed it takes longer to charge then an iphone but im not to fussed.
I wouldn't do it... your phone might turn into an iPhone
I've been charging with iPhone charger and had no dramas either.
Any electrical appliance will try draw what it needs regardless of what's powering it.
eg. It's supply and demand - you've got a tap designed to fill a 2 litre bucket of water in 4 hrs filling a 3 litre bucket.
If you want good charge times grab a 10 watt/ 2amp charger.
But there isn't a problem with what you've got if the time issue isn't a factor for you.

The N4 only pulls about 700-800mA max. So a 1A charger is more than enough. But as has been said, it won't make it charge any faster unless there is something wrong with your stock charger.

Install Elixir and charge your device with iphone charger and then stock charger. In elixir you can see at what rate your battery charges(mA). compare both and you be the judge of it.
Peace.
4 hours? I'm lucky if mine takes 2. It only takes 4 on the cheap wireless charger I have.

I've always wondered, why do people get so concerned about using different wall plugs? Surely it's the phone that controls how fast it charges and how much it takes in? My family has 4 different ones (LG/Nexus, HTC, Samsung and iPad) and I've just used whichever one was free without issues. Please correct me if I'm wrong but I've just never actually worried about this and it worries me that so many people worry about it
Anyway to see which charges fastest use something like CurrentWidget which displays battery drain and charge in mA.

I tried it out. Makes no difference at all.
Actually, it might be a little slower than the LG charger.
the service manual states 950mah to 90% then uses tickle charge, i use my sony camera charger at 1.5amps since its smaller, it takes like 2.30 hours to charge,

You are right, no worries with any usb charger. I've been charging my phone (N1, NS, GN, N4, Note 2) all using my old Sony Ericsson 700mA charger without any problem. Plug in before I go to sleep, then next morning it's full. Ready for whole day usage. Have been doing that for ages.
The iDevice chargers actually cut their output when charging a non iDevice. If you plug your phone in, sometimes you'll see Charging - USB instead of Charging - AC
I use my ipad charger, no issues but obviously I can't give input on charge time.
I stayed away from the stock charger since so many people had problems with it.
What about getting a higher amp wall plug say 2.1 amp at 5 watts and using FAST CHARGE?

I bought the nexus 10 a few weeks ago. I know it takes a long time to charge. I noticed when charging my galaxy note 2 with 0 lemon battery it is a 9300 mah, when I plugged it into the Samsung charger it charges 20% in 30 minutes so why doesn't the Nexus 10 charge like that when I use my samsung charger and it has a slightly smaller battery. I love the table I just hate the charging time. I did order pogo cable so I am waiting on that.

Buying the pogo plug was your best and only option to address this issue. No one knows why Google switched from releasing the N10 with a pogo charging cable, at the last minute, which I read a long time ago. I suspect it had something to do with the Android kernel not being able to charge through the pogo connector at the same time as the micro USB connector is being used. It may also be that other Android tablet manufactures resisted this new connection type. To this day the audio/video capabilities of the the pogo connector goes untapped by even custom ROMs.

I don't understand why Google makes a great product but does not have the forsight to address issues that the engineers know of at the time of a tablet release. The pogo charger and a kernel that would let the tablet charge faster would be a huge for them to keep the nexus 10 going longer into production. I don't mind that the tablet only gets 6-7 hours screen time with surfing the web or watching movies and about 10 hours with the cpu throttle back dimmer to 50 percent and wifi off when reading a book. I just hate the charging time, it should just charge faster lol. My Samsung galaxy note 2 charges faster with a bigger battery and that kills me lol it does not make sense.
Thanks for the reply.
