My Nexus 7 literally takes hours to charge

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

Nexus 4 - Xbox 360 charging problem

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

true, it could be... but i charge my samsung galaxy s2 using same method and that charges up fine without problems...

I have no problems with my 360'
But why would you keep your Xbox running at night to charge your iPhone??
Better use a wall charger. It charges faster, and is cheaper..

weirdly i dont leave the xbox on... the usb ports are still live when it is switched off and because of that reason, i use it to charge my phone.
PS its a Nexus not an iPhone lol

I had similar issues while charging through my laptop, My phone would say charging, meanwhile it would be discharging
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.

yes, i've tried changing the cable and its the same... i believe the comments above have explained it much clearly to me and make me understand why its not charging (xbox usb being 500 mah and the phone needs 1.2 amp... so looks like i will have to use my wall charger from now on)
i appreciate the help guys!! :good:

[Q] fast charge kernel

I must be doing something wrong, but can't figure out what
I wanted to enable fast charge, cause my device drains more battery than it charges, I installed the "fast charge" app from the play store, but it always says my kernel is unsupported.
I've already tried these kernels:
-franco (franco kernel updater)
-fugumod (fugumod updater)
-trinity (trinity kernel toolkit)
-faux (fauxClock)
-timur
and I've searched in each app for a place to switch it on but couldn't find it anywhere.
I'm running cyanogenmod 10.1
the tablet is rooted and unlocked.
anyone any idea what could be the problem?
thanks for your time!

Give NCX Kernel a go, I'm nearly 100% sure (99.9999%) that has fastcharge enabled.

so far, I've been unable to find a zip with that NCX kernel, so I could flash it, can you provide me with a link or something?
I only find .img files, and I'm unsure what I have to do with them :s

Don't waste your time. If you tread the reviews, your problem is common with that app. Download Trickster Mod and use that asp.
Also, fast charge isn't going to have any effect if you're plugged into an ac outlet.

Like najaboy said, fast charge has no effect using an ac charger. Only speeds up charging if your charging via USB.

Does fast charge via USB even exist for the nexus 7, because so far this seems like some sort of vapourware joke that doesn't exist.
My device is shot, the headphone jack has gone bad, and now regardless of what I do I will always get charging from USB. It won't connect to the PC, and won't power devices from an otg cable, I even made a fast charge usb cable that tricks the device into thinking its an ac power source..... It works with everything but this, so its safe to assume that if indeed there is no fast charge I will take great pleasure in smashing this to bits.
Has to be up there with the first generation Xbox 360 as one of the worst build quality devices ever made.

And even then only if the active USB device (e.g. powered hub) is also designed to not current clamp or fault-open at currents above 500 mA. It takes two to tango.
Even when it does work, it's nowhere near as fast as a 2A AC adapter, btw.

USB 3 can output 900mA

Any change to resolve this issue?
I have a 2A usb car charger, but is I use GPS programs (like waze) , battery drain in too high , and charging current is not enough.
Any Fast Charge supporting kernel could be the solution.
It worked very well in my previous Galaxy Nexus phone.
Any idea?

A kernel with fast charge is inapplicable to your situation. You simply need ausb cable that had the d+ and d- pins shorted.

USB charging issue after 4.3 Upgrade?

Wondering if anyone notice how slow it charges when it is connected to thru PC using USB (using original USB cable)?
I know it was not charging very fast when it was on 4.2.2, but 4.3 it is really slooooooooow...My N7 is pure stock 4.3 and so does its kernel.

were you using usb fastcharge on 4.2.2?

Unfortunately I am having similar problem with my nexus 7 after OTA 4.3; it charges so slow even though I plug charger in and try to use it while its chaging, device turns itself off saying please charge battery. How can it turn off when its already on the charger?

Has anybody heard of a kernel that fixes this? I love everything about 4.3 except that it charges sooooooo sloooooowwww!
I plugged mine in 5hrs ago @ 30% and it is up to 85% now... Ridiculous! This is using the original Asus charger.

Connected through PC only gives you about .5 amp charging rate. The stock charger gives 2 amps. If you aren't using the factory USB cable then most likely it is current limited and not applying full power while charging. If you are using the complete factory setup then whatever you are doing is causing the battery to drain faster than even a 2 amp charger can supply.

[Q] Pogo Cable Issue

Hello there developers,not sure if I'm posting on the right place but I have a really big problem. My new Pogo Cable arrived and I was so excited to use it,but my happiness didn't lasted fort too long. The problem is that the Tablet while charging with the Pogo cable is either charging slow ,or neither at all. This issue is available for both Lollipop and Kit-Kat,have upgraded an then downgraded with the hope that the issue will be solved. The original Micro -Usb cable works good but with the Pogo Cable in the Battery Monitor Widget it appears "Discharging" and "AC Plugged",and the charging rate is booring slow. Had the idea to measure the Voltage and the current Flow with a multimeter and got the surprise that while the voltage is 5.12 V the amperage is 0.12 A ,while the original charger pumps up to 2 Amps. Could this be the issue? Is there some electrical switch that should open and release all those 2 Amps or is this Cable a Hoax or something that is not fully functional? Thanks in advance,hope that you guys will enlight me somehow!

I've no idea if this is related but be aware that having your pogo plug connected while also having anything connected to the microUSB will stop charging. The charging icon (lightning bolt) will still appear but that I'd a false indicator. This limitation is due to the Android kernel and is present in all versions of Android.
I exclusively use a pogo plug to charge my Nexus 10 and it has always worked on all versions of Android including 5.0.2 which I'm on today. For me pogo plug charging has always been about 25 percent faster then USB charging.

My experience is exactly the same as 3DSammy reports.

well my warranty is expired so i Decided to "surgically" dissmantle my Nexus 10 in a heroic attempt to find the cause and I have made a breakthrough (or at least I tought so). I got another Pogo cable ,and this one was good,the voltage was exactly 5 Volts measured and the Amperage that I got was 2.21 Amps measured with a 6 Ohm fuse,all these values where from the original Samsung charger. All things good,but the Tablet is still not charging at all,the same Lightning animations and even after 3~4 hours still no charge at all,and this is Lame in my opinion. So after opening the tablet,I got the idea to short the 3 and 4 pogo pins together,and assumed that this will draw all the power that the battery needs to charge,the idea was working i got 20% more power draw than the usb cable BUT for only let's say Half of hour ,and then the same old story,battery was discharging but the lightning animation was on. This is not so good and my suppose is that the Power Management iC from the motherboard is some how not managing the Pogo charge at all :laugh: so my next idea is to wire the charging Pogo pins directly to the battery and hope for the best. Regards! :good:

I've got one of the original n10 from first day of issue. My battery is going to hell after being used and charged every day for the past couple years. It's been on/run everyday since Dec. 2012. I have always had a problem charging while using it. My display is always set at about 1/3 bright. When my battery drops to critical, I plug in the pogo and usually put it in sleep mode to charge. It will quick charge that way.
If I still need to use it at critical battery level, plugged into the pogo plug, it maintains power and possibly gives it a very slow increase in charge. Almost none noticeable, but will maintain power level (unless tons of graphic, camera or movies along with full bright screen).
I've just taken it for granted that this is how it works. Pogo plug will maintain battery while using and will switch to quick charge once put into sleep mode or powered off. It's always acted that way, so I have never known anything different.

Well I'm sure about what did you said,but in my opinion this is a marketing bulls$h*t. Why would I use that Pogo cable if it's role is to charge only on sleep mode and powered off?I ordered because I thought that like the instructions of the pogo says:" it will charge the battery even when you are using it for movies and browsing,being more handy ,because you have the micro USB port free." I play games ,I surf the web,so my tablet is hooked up to a USB hub so I have connected a mouse,a keyboard and a game controller,so my USB port is full,and I hoped the pogo will help. Charging only on sleep is equal to zero for me,I need live charging,in the same time as the tablet runs games and other stuff. In my opinion this "glitch" should have been told on the pogo site,so I could full understand this cable and it's role. Shame on Samsung,30$ .for nothing! Thanks for the help!
