How are those who've got their N10 finding the charging speed? Mine arrived yesterday and has been charging very slowly, as the reviews had said.
In six hours last night on charge whilst left on standby, it charged about 20%. Is everybody else finding a similar situation?
I'm looking forwards to the pogo-pin chargers/docks being released, which will hopefully charge a bit faster! If anybody knows how to hack something together to make use of the faster charging speed on the pogo connection then please do share! :good:
Of course, you have to look at the amperage and watt of your power supply. Even among the AC powered chargers, they vary greatly, and here you are talking about charging this behemoth with a measly powered USB.

If it takes 6 hours to charge 20% on a 2amp charger than that is seriously messed up.

Not messed up, just physics. There's an awful lot of resistance in a 9000MaH battery, and a standard microUSB (or even full-sized USB) connector can't handle the amperage that a faster charge would require. Which is why most big tablets had proprietary connectors up to this point.
But guess what? Google and Samsung knew this, it's why the N10 has one too, we just don't have the cable for it yet.
Pogo charger is coming, supposed to be at least twice as fast. Don't know why it was delayed, but most likely either a certification issue, or worry about Apple suing for it being too much like a Mag Safe connector.

Are the slow speeds people are getting from the wall charger our from a pc connection?
Are you saying a powered USB hub is charging it quicker than the mains charger supplied?
Thank you

I don't even charge phones via normal USB on PC anymore, let alone a tab. I've found the charging time on the N10 to be ok, provided the screen is off and also if I'm downloading something it seems to slow the charging down. Other than that it's not lightning fast, sure, but I'm ok with it. And so much the better when they release the pogo charger.
charged mine over night yesterday from 10% to full wall mains, but when the screen is one it doesn't seem to charge just maintains current charge which is a bit annoying

Try turning anything that uses power off (i.e)...turn the screen brightness the lowest it will go, turn the tablet on airplane mode. Turn the sounds off.
I find that helps my phone charge faster, maybe this will help with the tablet.
Are you talking about charging via USB on a PC, or via the PSU?
Through the PC will be very slow at a maximum of 500mA, but the PSU should be able to power it? My N7 and Galaxy Tab 10.1 had 2A chargers - what does the N10 come with?
I am regretring more and more buying this. I haven't received mine yet but the amount of pixels is kind of ridiculous. I would have been happy with 1920x1200 with that beasyly hardware. Saw a review that said their battery only lasted 4 hours because of the insane power the screen sucks away.
Also the fact that this pogo charger will probably cost $50+ and it is something that should have been standard either way.
Oh Asus infinity..why must your I/O be so god awful. You were almost the perfect tablet

Yeah charging is slow, though not as bad as 20% in 6 hours! I think mine was charging faster than that even when I was using it. I think trade off is worth it though with the microUSB connector.
The iPad 3/4 is no better... Takes forever to charge

It's nice to know that we have the Pogo pins option for faster charging. It makes me feel better now going through with my decision to get N10. I am a heavy media/game consumption guy so this device is perfect for my needs.

My nexus 7 has been plugged in since 7 hours and still is just 70 % . using official asus wall charger rated 2.1 A . stock rom rooted device
Problem has been persisting since many days now . usually charges at this rate only ! While at 4.1 it used to be fine but now at 4.2.2 charges this slowly . please help..!
Here you go.
Please correct me if I'm wrong... I've had a quick look through a few of those threads and it seems as if there is no real solution? The charger that the tablet comes with takes many hours to charge the device fully?
Ridiculous! I hate that while I am using the tablet when its charging the battery still goes down (despite being plugged in)!

- you could have a bad battery
- you could have a bad charger
- you could have a bad cable
- you could have a variable amount of power drawn by an active device - which depends on what apps you have installed, your screen settings, kernels used etc cetera. (read : VARIABLE)
- you could be trying to charge the device via a USB port, which provides only 500mA of current - less power than the device uses in certain screen-on scenarios (esp. the 3G model)
Until you run tests which are meant to discriminate between these different scenarios, you will be just wandering around in the dark.
So try this - run the battery down through normal usage (not too far though) - say to 10%.
Then, turn the tablet off (not just the screen, I mean powered completely off).
Then charge it (on the 2A AC charger!) for about 75 minutes. Boot it up and see what the battery charge state is. Then, power it off completely again and charge it more (on the 2A AC charger!) for another 75 minutes. The first 75 minutes should bring it to somewhere around 50% charge, and the 2nd should be enough to bring it to 100% charge.
My (December '12) N7 charges from about 4% to 100% in 150 minutes (2.5 hrs) when it is on the A/C charger. That seems pretty reasonable, as 4.325 A-h / 2.5 hrs = 1.73 Amps.
By the same simple maths, a 500-mA current limit (e.g. USB hub/computer port) should take 8.7 hours to charge the N7 - even when it is completely turned off! And if you are using the device in this scenario, it might not charge at all!
This will at least tell you if there is a problem with the battery, charger, or cable. If it takes too long to charge when there's no software running, then the problem can not be software, right? (There's no software running with the device powered off.)
If it turns out that the battery/charger/cable seems OK in the above test, then the next thing to do is to determine what you have done to the stock configuration (in the way of adding apps, whatever). It's easy to say "4.2.x did this to me" or "4.1.x was so much better", but there does not seem to really be any compelling evidence coming from a majority of users that this is true.
I don't deny that people experience battery troubles; otoh, I'd wager that the root-cause of 95% of the trouble falls into two basic classes: defective hardware (incl. worn-out batteries and/or loose battery terminals), and user-caused software additions/changes.
good luck
I've had experience with 3 models that all three had power issues. Reconnecting the battery cable solved it for me, but in my case the N7 went 'dead' on me, didnt notice slow charging times. Disconnecting the battery cable for 30s then reconnecting and powering up solved the problem for me. Left me thinking their battery hardware assembly is very flawed. Or my local store has had a bad batch.
I found this movie helpful with the unhooking of the connector (at around 3:30)

Many thanks for that response. I will try out for sure.
My nexus device has stock ROM (not rooted) so I hope its a charger issue. Then the issue will go away quickly by replacing the charger.

tried out charging it up from 10 % to 50 % .. took around 3 hours !
similar observations while charging till 100% ..
It turns out that the charger may be faulty . I'll have try out other chargers. The problem is that I am here in india and made my relative bring it for me from the U.S. . I can't find any trusted chargers here . I'll try charging it with the other Sony charger I have (rated at 850 mah ) and compare the relative results . Thanks for the info anyways !

850 mA is going to charge pretty slowly also. Appearances (simple maths, A-h = Amps * hours) are that to get a 2.5-hour charge (4% to 100%) you are going to need a 2000 mA (2 A) charger.
As I said before, not accounting for losses the 4.325 A-h capacity of the battery works out to 1.73 Amps for 150 minutes. But probably due to losses the current is in fact higher - perhaps very close to the 2A limit of the US OEM A/C charger.
good luck
AW: nexus 7 charging awfully slowly !
This could be the solution:
It seems that the charger marked as 2amp is only 1amp: see this[first result googling <nexus7 battery charge slow>]:

Otherwise, i have the prob that my n7 needs about 20 hours to get fully charged via AC and the charge even decreases if i use the tablet. Has anyone an idea what to do?

OK I've tried different chargers and different locations but still no luck. My n7 takes about 8 hours for a full charge and if I use it while its charging the battery still decreases. Bizarre!

I have posted a thread to post my case: http://forum.xda-developers.com/showthread.php?t=2126185
After posting that thread, no help worked! So i came to ASUS to replace the mainboard and it charged normaly again (3 hours to 100%) but no for long, now with turning-off Nexus 7, it takes me sometimes 6 hours, 7 hours, 17 hours to charge....
It happened not only on my device, but a lot of devices of tinhte.vn members.
Hardware issues? I hope I don't need to change my mainboard again...

I use an OEM charger - no problems.
I suppose that Asus could be multi-sourcing them from a variety of suppliers though, and that could account for different experience.
(Either that or something worse - funny business in Asus' supply chain or in the retail sales chain. There seems to no limit the amount of counterfeit electronics from the pacific rim and batteries & charger hardware seem like a likely place for that kind of activity).

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.

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?

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.

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

Like the title says, my dad just bought a Nexus 10 and when he was charging it from 20%, it's taken more than an hour to charge to 50%. With that logic, the battery is only charging 30% a day, which means it would take 3-4 days from 0%-100%, and that simply is unacceptable. Is it a defective unit? I know about the Pogo charger, but I'm sure he'd rather not spend $25 on it just to find out it doesn't work.
Any suggestions or ways to fix this?
Thanks.
edit: To make things even sound worse, it only charged 2% in 1 hour and 30 minutes.

All I know is that on mine takes about 9 hours to charge with the original charger. The first time I've charged it from 16% with my Galaxy SIII cable, and it took over 14 hours.
That does seem long. I have the pogo charger and it does charge faster.
Before you buy the pogo, are you using the chargers that came with the N10? When I charge my N10 from a laptop/PC, it does charge slowly. So make sure you're charging with the correct voltage/amps.
Good luck!
I'm having a similar issue since the OTA update to 4.4.2.
I'll try changing USB cables, but I'm not optimistic. I'm tempted to try a factory reset if a different cord doesn't work.

Do you use the tablet while charging?
Is NFC enabled?
What setting is the GPS on; device only?

With Wifi on, NFC off, Location set to device only, bluetooth off, screen off, using my Pogo cable I get about 22% charge per hour so from 0% to 85% is 4 hours. Whilst on Pogo if I turn brightness to full and sound full then charge is held roughly flat. I moved to Pogo from the supplied cable as when watching stuff even when connected it was discharging, so now I'm never really out of power unless I stay unplugged a long time (about 6 hours unplugged max on low brightness)

This situation happens when the tablet isn't even on, so certain settings being enabled are not the issue.
And for more info, he is using the charger that came with the tablet, so we've just decided that we'll just send it back and get a new one because the battery is obviously defective.

Have you tried a different cable/charger? AN hour to charge from 20% to 50%? Sounds about right to me. I always switch mine off when charging, I can live without when it' off. :good:

I think clearly a human error in the word chosen explains it.
Instead of "...was charging it from 20%, it's taken more than an hour to charge to 50%. With that logic, the battery is only charging 30% a day, which means it would take 3-4 days from 0%-100%, and that simply is unacceptable."
it would make more sense if written "....was charging it from 20%, it's taken more than a day to charge to 50%. With that logic, the battery is only charging 30% a day, which means it would take 3-4 days from 0%-100%, and that simply is unacceptable. "
.... then the later post of its a dud and its been replaced makes sense....

Ahh, I see. Good call in getting it replaced. I hope you have a better experience.
here are a few points
1) the AC USB come with N10 charge up to 2A.
2) the mini USB limit to about 1A
3) if you use other mini charger, that 1A is even smaller.
4) N10 battery is HUGE comparing to all tablet out there. It will take a long time to charge
Solution: get the pogo charging cable that cost $25 (very expensive and can only use for charging), that will fully charge 2A to your tablet which should reduce the time to less than 4hrs given no other power hog apps running at the same time. It will charge slower if that power hog app running too. You can tell by how warm/hot your tablet gets when running such app.
btw, go look at the disassemble of the N10. That battle makeup most of the tablet. LOL

Agree, BUT once you get >85% the rate of charge intake drops. I can get to 85% in 3.9 hours using Pogo cable, but that last 85%-100% is slower. My battery meter sees one kink 85-90 another 90-95 and a slow crawl 95-100. As the battery is not taking up 2A >85%, all chargers, all cables, will largely take the same 85%-100% but the Pogo cable with 2A input will get you to 85% quicker.
I have moved to a dual 2.1A output PSU.
duplicate post.

I know you revised the post but just looked at the link to the PSU you mentioned.
Note that $10 one is dual USB socket but only 2.4A total meaning if it is charging the N10 taking 2A it can only offer 0.4A to something else meaning that other thing can only be something like a phone. More importantly is the opposite if you connect a powerpack USB battery which takes say 1.5A or 2A then your Pogo cable cannot deliver its full capability.
The PSU I mentioned earlier is dual 2.1A both concurrently meaning it can charge the N10 and something else also power-hungry like charging a 2A input or 1.5A input USB battery.
There are PSUs out there which can do 4 lots of 2A concurrent, I didn't get one as they were getting chunky and personally prefer two PSUs, a 2x2A + 1A for total 5A which does my N10, my USB battery (2+2) and my phone (1) concurrently taking two power sockets.
Check the details of specifications of these devices, PSUs and batteries vary wildly.
