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

Is it alright to have the SGT plugged into a USB port all day (approx 9hrs) ? I'd like to have it keep its charge (maybe even gain a little) while I'm at work so I can have a decent amount of juice for the trip home and until i go to bed. Or is this a good way of burning out my battery real quick? Thoughts?
Oh and as a side note on USB charging, I was able to get from 15% to 99% in 7hrs with the screen off the whole time.
Is it a slow-charging USB port? Or is it a powered hub? If I'm not mistaken, slow-charging a lithium-ion based battery pack is actually better for its life as opposed to rapid charging.
Its the regular port on the PC not even high speed usb so i guess it isn't powered.hmm guess the charging part is OK..but what about leaving it plugged all day even if the battery is at 100%?

All usb ports are powered by definition. They can supply up to 500ma (half an amp). Dont worry about leaving your tab plugged in, devices are smart enough these days not to overcharge the battery.

Coda is right, technically they all have power . If not, how would any device charge? I guess I really meant to say USB ports charge at a higher MA or something for rapid charging (wall-socket USB adapters?).
Also, Coda is right again. Devices these days are fairly smart. I typically leave my HD2 plugged in all the time with no problems.
itll be just fine plugged in!
ive been part-charging mine at random intervals (sometimes for 20 mins at a time a few times a day) and leaving it charging over a day from both powered hub and charger over about five months... though i have had two or three near total discharges
the battery has got better, which is what you would expect from the tech - sammy even provides a nice notification telling you the device is fully chraged
i wonder if they put that in there to account for unexpected battery problems down the line? in any case, ive read that low-powered charging, even unregistered by the battery, will increase the lifetime of the battery and also charge at approximately the same rate... ive seen this with my phones charging over pc usb
Great! Nothing to worry about then. The tab would look really cool on my office desk sporting the same screensaver as my PC ..'the Matrix' scrolling code.
I think it is OK. I bought a 2d adapter, one for the office. Since Sammy is selling docks, it also means that it can be powered all times. On the other hand I remember my Archos which I used to leave it on its dock all times... battery was killed in a short time. When you sell multimedia charging docks it means that you can leave it there, no? Not in the case of Archos.
So I realized that if I charge my phone using the USB ports on my laptop, the phones batter lasts much longer than if I charged it through the power outlet in the wall.
I didn't take any screenshots because I didn't think of it at the time, but through the laptop I got about 2 days and 14 hours with moderate use and I had 18% battery left.
Through the wall charger, I get about 18 hours with moderate use.
Can anyone else confirm?
Not sure, but i do feel that it charge slower on the USB port of my laptop. Maybe it have something to do with your theory.
Centranly!
USB port can give max 500mA but the wall charger can supply with 700mA (+40%!!!)
I have a charge-only cable that charges over my MBP's USB faster than any AC adapter I've tried. Charges last about the same regardless of power source though...

USB 2.0 will provide up to 500mA while USB 3.0 can provide 800mA. Stock Atrix wall charger I have is 850mA.
How do you verify what mA you're using? Is there a good tool for that?

IIRC, these are minimum specs for the standards. Could be wrong, but I believe that true output varies card to card/port to port.

I've heard this theory before, but didn't see noticeable difference on my phone to back this claim.
I do agree with OP that charging the phone connected to a laptop USB port would give longer battery life. I have noticed this on several occasions already. I also agree the charge process would be much slower. With my phone, with 5% charge or less, the battery icon randomly doesn't animate while being charged.
That a side, I'm also sure something is broken in Atrix design, be it hardware, battery, or both but something is not right. I can't even charge my phone from a power point with the supplied cable and the plug [UK].
I know Motorola won't admit neither fix this problem in Gingerbread but might do, quietly, in ICS. One other possibility I can think of is that the supplied plugs are the culprit.
Today i charged the phone from my laptop, and im not feeling any difference at all. Its discharging at my usual pace. :/

Furthermore to my previous post, I have finally found the opportunity to test my phone with a Blackberry charger and it started charging the phone from the power point. That means the Motorola UK plugs I have are broken.
I'm arranging to purchase a Blackberry charger now. Don't want waste my time and money with Motorola anymore.
If I have the screen on while plugged in, my battery % continues to drop and the device itself feels kind of hot. Could I have a problem or is this normal?

Mine doesn't it keeps going up, though I haven't tried playing games. It does depend on what you are doing with the device, if you are running applications that max out the processor it will possibly drop.
The GSII would drain while plugged in if the screen was on. You would see a noticeable drain while using GPS and Music and driving. The only way to make it work was to turn the screen off on the device, the GSIII has a better charging chip in it, and it isn't limited to 650maH (from what I can tell since it is charging when using GPS)
I noticed it while using a usb car cigarette adapter as well as a usb port on my laptop. the car adapter is a 2 amp charger capable of charging a tablet. I will see how it performs with the oem wall charger.

I'm curious about this myself....I'm leaning towards not leaving mine plugged all night. I 2 have done this in the past with other phones and can't be certain but maybe this is a rEason I had horrible batt life despite efforts to Better it. So I'm gonna stick with charging/topping off when I can. Gonna start just charging when I wake up while I'm getting ready for work. I did notice that when battery is completely charged a message comes up telling u so and to unplug. So I'm gonna follow directions haha.
Sent from my SAMSUNG-SGH-I747 using XDA
All modern smartphones have chips that control power, and cycle charging appropriately to not abuse the battery. Many phones monitor the temp of the battery and such to ensure a good and safe charge. You can leave it plugged in overnight just fine..
It definitely doesn't like 3rd party adapters. I'm hoping it will at least accept the tab adapter with samsung's cable so that I can charge it at work without buying a dozen chargers, but...
(One charger I used is understandable - turns out its only 300ma. Whoops! But using full 1A chargers wasn't helping either, it went up maybe 1% every 15 mins. The stock charger ran it up fast enough that it was charged from 70% in under an hour.)
I use SetCPU and have a setting to reduce the clock when it exceeds a temperate parameter. You could also set a max clock for when it is plugged into a USB (Computer/Car charger). That could help it stay cooler and charge faster while not plugged into the wall.
I charged from empty to full this morning when plugged into the wall in about 3 hours. I haven't tested on my computer yet.
I went through this when I first got my Evo 4G. I did not realize at the time that the 500mA charger I was using with my Blackberry Storm (horrible device) would not charge my Evo while doing anything power intensive (like using GPS) and I quickly drained it on a car trip.
I went on Amazon and bought a $20 Schosche iPad charger that claimed to provide 2.1A which should be plenty. On that charger the phone would charge while using GPS but very, very slowly.
After some more research I found that some chargers caused the phone to switch into "USB" charging mode and others would switch it to "AC" mode which would draw much more power and charge faster.
This is the charger I ended up with and it works great:

My Evo charges just as fast as it does on the OEM wall charger. I don't have my SIII yet (thanks Verizon for being the LAST in the US to ship them out...) so I can't yet say if this holds true for the SIII but I assume it will. At $1.22 it's not much of a gamble.
Hi guys,
currently having a problem with my xbox 360 charging my Nexus 4...
basically i put my nexus on charge (usb cable from xbox 360) over night and it clearly said its charging, so i woke up the next morning and the battery % was as i left it, but it still clearly says charging? this has happen to me twice this week... has anyone else had a problem like this?
forgot to mention, i have always charged my mobile devices using the xbox 360 and never had any problems before...
Maybe try other cables?
I have had similar issues with phones in the past where certain cables worked and some didn't.
accidently gave u a thx I had this problem with all my phones trying to charge them with my PS3 or PC. With my PS it charged 1-2% and with my PC a bit slower than normally. I think its the bad electricity supply over usb

I think it has to do with the phone using more power than the port is giving out. Basically some apps you have one your phone is using so much battery that the charger is not charging because the required power to run the phone is greater than the charge is giving. I'm thinking this is becasue the phone has so much RAM that all the background apps are using more and more power. It's like charging a Laptop through your Xbox USB port, the laptop uses WAY too much power for it to be getting charged through a measly USB port.
Nonetheless, I stopped charging my phone through my laptop and just plugged it in the wall. It charges way faster anyway (my charging usually takes 2 hours when it's really low to full battery)
Even if it does charge, it's not likely to charge well; the Nexus 4's charger is 1.2 amps. The Xbox USB ports likely put out less than half that. Unless you have an S model, in which case the rear "Kinect" port is "high-powered," which likely means 1.0 amps.
I'm charging off my AirPort Extreme without issue...albeit it slow. Since I charge at night, it's a non-issue. OP, have you tried swapping USB cable?
Does the Xbox 360 temporarily disable its USB port if you try to pull to much power from them?
The Nexus 4 requires more than what is supplied...
uberSlackr could be right, normal usb ports are 5volts,500mah, so 5 volts standby, you should be able to charge even at a slow rate, windows 7 has an option to turn off usb ports to save power unless you disable it.maybe xbox has a similar power saving function.
samsung s2 max charging rate is at 650mah, my nexus charger is 1.2amps, so 1 amp draws too much.

i appreciate the help guys!! :good:
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.

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?
