how long does it take to charge your nexus 7? - Nexus 7 Q&A, Help & Troubleshooting

Mine gets from 0% to 100% in about 6 hrs. Is that normal? Wonder if it seems a bit too long that's somehow contributing to my battery issues.. use original charger plugged into a wall socket.

Yes, I believe that is normal. I just did a charge today, from 0% to 100% in about 4.5 hours. Quite quick I was very surprised.

Six hours seems pretty long. The lowest I've let my battery run down to so far is 55%, and it took two hours to get to 100% on the stock charger.

I get full charges from 10% or so in 2-3 hours.

did you use the original wall charger or you charge it via PC's USB? I guess the wall charger is a bit faster.

The wall charger should be around 4 times faster. You computer outputs around 500mA where as the wall charger is 2A (aka 2000mA).

Don't use third party USB cables with charger it also charge the nexus 7 slowly. This is what I found when I first bought it. Using original cable with original charger seems to charge it very quickly.

I'm using stock cable and charger plugged into the wall socket. Everything else is perfect, and not enough to return but a concern nonetheless. My Toshiba thrive charge blazing fast at 0_100% in 2_1/2 hrs.

Any other input?

When you are charging, is your Nexus 7 powered on, or does it display the battery icon in the middle of the screen?
For reference, mine was powered on when it charged from 0% to 100%.

Long time to charge ?

My Galaxy S, takes far too long for charge completely ؟
Today was the battery level of 19%, Connect the device charger, and after 5 hours and her grandmother, reached 93%
also the phone became very hot
Yes, I am also wondering about that. It takes about 6 hours to get from 5% to 100%. It is fine for me, since I charge the battery in the night, but sometimes there are situations where you want to get your phone charged quickly.
My previous iPhone 3G took about 1,5-2 hrs for complete charging.
I can't offer any advice as to why, but my phone charges from 30% to full in about 2 hours if I use the mains charger, but takes about 3-4 hours if I plug it into the computer USB port. The other thing, my phone doesn't get hot, only slightly warm.
I thought the same when I first got the phone.Have owned an iPhone for the last 3 years and that chrged up pretty quickly using the USB charger, in fact the Wall Charger is still sealed,never used.
But using the wall charger with the SGS really makes a difference.I would say under two hours from empty to full.

the usb port on a computer can only deliver i think 0.25amps where as a typical wall charger can do 1-2amps which is alot more. There it always charges quicker with a wall-plug-charger.
Sorry, i am from denmark, therefore my native language is not english
mine charges from 10% to 100% in arround 3 hours using the original charger...
I had the same problem initially, just do a few full battery cycles (2-3) and it should go away. If not, it may be faulty - how's the battery life?

Are you using USB or AC charger?
AC Charger gives you shorter charging time because of the higher amp input.
my SGS takes around 2 hrs from less than 10% battery in balance to full charge via AC charger.
The stock wall plug charger rated only 700miliamp, if you need fast charging you need to get a charger rated min 1amp, I use my old n97 charger to charge sgs, take about 2hr fr.black out condition, the charger rated 1.2amp output

Ampere rating is a max spec, the phone will pull as much as it needs. So you gain nothing from using a higher rated charger.

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.

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.

[Q] Nexus 4 Charging Very Slow

I am not sure if anyone else is experiencing this but I am seeing that i'll charge my phone for somewhere between 5-8 hours using the original wall charger and cable but it will not fully charge. It gets to about 70-80%. Is this happening to anyone else?
Any other details? Rooted? ROM?
My phone fully charges from 10% to 100% in about 2 hours or less
Sent from my Nexus 4 using xda app-developers app
5-8 hours is definitely not normal. It fully charges from 0 to 100% in 3h 45min Max and even that is a little bit of a stretch. For me its more like 3hours.

Check your chaging status. If it says USB, thats your problem. Without further knowledge of your setup, I cannot advise you any further
Just happened to me, plugged into original charger before going to sleep, woke up and it shows only 80%. Plugged into Samsung charger, now up to 90% in 20 minutes.

Stock everything. It's happened about 4 nights now.
I find that sometimes my stock charger detects as USB instead of AC. You can see if it is charging that way in the battery details in the settings. When it is stuck on USB it is way slower.
Sent from my Nexus 4 using xda app-developers app
Yeah and if you want it to charge a little bit more faster you turn off the device
Check about phone, make sure it says Charging (AC) and not Charging (USB). If it's USB then thats the reason why, use another charger.
My stock charger that came with N4 went to USB but then for some reason, after I replugged it, it went to AC and has been AC ever since.

youre welcome. fast shipping too! it was supposedly be here monday, i got it today.. beautiful charge. AC all the way. Good use for the USB cord is ADB and updates
cant seem to spread the word enough because youre the only one that replied about it. couple threads that ive mentioned it but nope, they think its phone related problem or the cord.. cord, yes, because its a USB cord to an AC adaptor, duhhh!!! nothings perfect
I was having a problem where mine, with the charger that came with it would charge very slowly, once overnight only got to 80% in ~8 he's i watched it and sometimes would not even show charging on the lock screen. I switched to my HTC one s charger and it is charging with great speed. Issue with these chargers?

did your HTC One S have an adaptor like the Nexus 4 or any other phone now a days... I think thats the probllem. having an adaptor from USB to AC PLUG messes with these phones. Like I said before, above post.. buy an LG AC Wall Charger.. works great.

[Q] 3 Hours of Charging = 30% Battery

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.

Discharging while plugged in to wall?

My nexus 4 was all fine till I flashed the r22 kernel.
My phone had about 22% battery left, so I plugged it in to wall, and I started using it at the same time
To my surprise, after 2 hours of being plugged in to wall, the battery has discharged to 19%! And I've been only using Whatsapp with lowest brightness! no heavy usage!
So I left it there to charge without using it, and it reached 95% in about 7 hours! (usually it took 2 to 3 hours)
I reverted back the kernel and the ROM and tried again, with no success! It goes through the same behavior.
Any Ideas? Is something wrong with my device?
are you using the original charger? my nexus 7 discharges while plugged in if I'm using my nexus 4 charger

Could be the cable? Im using its cable but plugged to the pc.
I am suffering from something similar since updating OTA to 4.2.2. I'm using the official charger and always charge overnight but twice in the last 6 days the device has not been fully charged in the morning. Looking at the battery graph it reached 100% in a few hours but then slowly discharged despite still being plugged in. I use the Clock Daydream in Night mode (and always have, since I got the device in November) so I'm going to disable that first and see if the problem exists. If so then I'll try a different charger. If that fails then it's factory reset time.
it is strange that after reaching 100% plugged it in to wall if i use it to listen to music or something like that still plugged to the wall it discharges to 99%.
This makes no sense to me a phone discharging while plugged to the wall
same thing's happening to me. not really that bothered but I want my phone to charge and not discharge when I play music. ;(

Yes, I've had the same experience since the OTA 4.2.2 update. Went from 8% to 1% while running nothing but XDA app at lowest brightness. Stock charger. Never had it happen before update.

That's your issue, your PC's usb only supplies 500-+ mA for charging. The nexus 4 original charger is 1.2mA.
It's the stock charger, it sucks, try re-plugging the cable several times (check in battery, if charing says "AC" instead of "USB)

Once your phone reaches 100% it stops charging even if it's still plugged in.
