Anyone else having a similar problem or know of a way to fix it?
It takes a *while* to charge. Mine just hit 60%.
We shall see, been charging all day... anytime i take it off charging drops to 40ish%
Im using battstatt and it drops by 10 percent.....90.80.70 im gonna let thr battery die completely before charging and see if it changes

OK, I just saw this in another thread too... mine has maxed at 60%. Gonna le it rest, shut it off over night and put it on another charger. See what everyone says tomorrow!
Seriously guys, charge it from an outlet. It charges *really slowly* through USB.
anyone else go through the initial charge, recharge and have it at 10% 9 hrs later?

10 hours total on 4G? That's not terrible.
Charge via USB that is connected to your PC takes forever...but it does charge.
But if you unplug it and charge via the power adapter, it is much faster.
i charged mine via usb and the wall socket, wouldn't go past 50%.
I went to bed and plugged it in to teh wall charger (charge for ~7 hours), checked when i woke up, 50%
went to the verizon store and they gave me a new battery (started at 50%). plugged the phone in 2/3 hours ago, im still at 50%
my dad mentioned it could be a bad fuel gauge chip (he works at TI)
So for whatever reason, you have to use the charger that came in the box. I've had the same problem, but it was because I was using chargers from older Moto phones and HTC phones. Now that I'm using the actual Bionic charger, it's charging fast like it should.
Silly, but it apparently is the case.
I bought a wall charger that you take the battery out of the phone and charge.takes 2 hours with xtra battery 15 bucks mobiletech

From what I've read about newer handsets, the phone needs some time to figure out know how to convert raw readings into percentage of capacity. I believe, the phone figures out how much charge a battery has based on the voltage. And, I don't think the relationship is linear.
My battery seemed to be horrible the first day. Today, I've gone through 30% after 5 hours, with the screen being on for 35 minutes and wifi connected for just under two hours. I don't know if the battery is "breaking in" or the phone is reading the level differently, but things are looking better.
Hi,
How long does it usually take u guys to recharge ur note from dead or almost?
It took mine. Over 8 hours to charge from 12%.
Also if keep my note on charge but im usimg it for browsing or whatever, my note still dischares.
Is this normal for the note as my htc Desire didnt diacharge while using it while connected to the charger.
Thanks
Neil

Hmmm I've never really timed it but its gotta be around 4hrs for a full charge.
I have been playing Stardom even when charging and it gains battery.
That doesn't sound normal at all.
If u r charging from USB port den its possible. Charging from ac will be a different story
Sent from my GT-N7000 using XDA
Charging by USB is at around 12% per hour, so it does take 8 hours.
Charging by a/c is upwards of 35%/hr.
Some of the apps usage would demand battery usage at 20-25% per hour, so if your battery usage is more than your charging rate then you would be losing battery which is what might have happened when you are using USB charging etc.
If your stats are for a/c charging, then I suspect the charger.
Yeah i charged for 8 hours with ac and also got discharge while using the note and charging.

Depends on what you are using for, but it still doesn't sound right.
Mine charges from 5% to full in about 3 hours when it's just sitting
on the table and I'm just using it for a phone call every now and then.
charging shouldn't take more than 4 hours when done from an AC outlet. just check if you have original batteries and charger. if not, take it to the shop and get it replaced immediately. 8 hours is just too much.

When you are using it heavily while charging it might be normal,
try leaving it alone while charging for one cycle, that'll give you
an indication.
If it's still substantially higher than 3 to 4 hours under these circumstances
you've got a problem, either battery or charger have an issue, or there's an
app sucking battery like hell.
as said, 3-4 hours is normal. Do you have a battery drain issue when in normal use? if yes, then u can use betterbatterystats to check which process is using the juice.
Also, its advisable (in the first cycle after flashing a rom) to charge the phone with switched off. After full charge, take out the battery, wait for 1 min , reinsert & restart. This will help to reset the battery & start afresh.
From 8% to 100% with the charger it took me less than 3 hours.
I only charge by USB on my PC and its never taken close to 8 hrs for a full charge..
The only time charging has taken a very long time for me is when I ran a ICS ROM.
So i did a charge with my usb cable and it tool half the time. Maybw theres a problemwith my ac charger.

How long does it take your Tab to charge from about 0-20% to 100%?
It takes mine forever - about 16 hours, although I'm on stock Honeycomb rom

I'm not completely sure, but 16 hours seems to be too much to me. I usually charge over night, so i guess it might be something around 8 hours.

I think so too!
I just wonder what is causing this... (1) some faulty chip in the tab itself, (2) faulty battery, (3) faulty Samsung cord or (4) faulty charger. No way to find out for sure, unless I return it to the shop and wait about 30 days (at best) while they figure that out and give their verdict
I hope someone has\had this problem and knows what exactly was causing it.

the last 5% take forever. That's usual behaviour for charging. Check out how long it takes to charge to 90% or maybe 95%. Should not take longer than 6 hours. If it does then maybe try a different charger or reset your tab to make sure it's no software bug.
Hard to tell the real source of error, sorry...
Are you ABSOLUTELY certain to be using the original, for your tab, charger, with a 2 amp output.
With such charger, it should be about 4 - 4.5 hours.
But if you are using a generic, or something made for an avg phone, with .5A output... Well 16h seems normal

I am using Samsung banded charger that came with the Tab.
Sometimes it does charge fast, but most of the time it either charges very slow, as though it were charging from USB, or doesn't recognize the charger, or even says it's established MTP-connection...
from 8 to 10 hours on hc 3.2
but now on ICS take less
using the charger that came with the tab, you should get charging times around the 4/5 hours. HC 3.1 and 3.2.

Does the cable work properly when you use it for USB operations (file transfer, etc.)?
If so, then maybe the charger is broken/faulty. Samsung (in its infinite wisdom ) put a resistor network in their chargers so that the tab/phone can recognize a charger vs a usb connection ... or maybe just to make money from over-engineered accessories. who knows? However, if that resistor network has failed (or the cable is broken, hence the question above about USB operations) then the charger will present as a USB port rather than as a Samsung power source.
Oh! Another data point to consider: does gently wiggling/straightening the cable when it's connected cause the behavior to change?

There isn't much difference with ICS 4.0.4 US rom in my opinion. And it is still picky what chargers it accepts when it's turned on (DX.COM charger works for me). I usually turn the TAB off and use a stronger charger, but it still takes a LONG time to charge in my opinion. I do an overnight charge as much as I can.
Did an overnight charge with the Tab turned off, and it charged to 100%, finally. But when it's on (even in airplane mode) it only charged to 60% last night (took 12 hours!).
Weird)
i always charging my tab from 0 or 2-5% to 100% either when powered on or off and it always takes 5 to 5 1/2 hours. no more and no less with default charger set.
first i thought it was taking too long but when i saw this thread i'm glad its only 5 hours

Common belief (knowledge) is that this is not the best for a lithium ion battery... It increases the wear, gets it to lose capacity sooner... If possible, charge your battery often, like as soon as you can below 75%. Only occasionally drop battery to 0%. IIRC, there's a good website called "battery university" talking about that

Thanks, used your post to fix mine. I ended up replacing the cable and not the charger. I'm using an original charger with a new cable now.
I am seeing same problem with my brother's 7300 tab as well. Its taking around 10 or more hrs to charge.
Anybody got tablet replaced in warranty for the same reason? Even with Nexus 7 original 2 A charger its taking too much time. With samsung original charger also it was taking similar time so i am sure problem is with the tab only.
4-5 hours on mine.
Sent from my GT-P7310 using xda app-developers app
Many Galaxy tab 8.9 owners have reported experiencing long charge times to the tune of about 16 hours, me included.
Solution:
Plug in the charger to the tab very very slowly. The charge icon in the system tray has a lightning symbol on it aka normal charge.
Connecting it at normal speed results to the charging icon in the system tray having a cross on it. It then charges very very slowly.
Why should we need gymnastics to normally charge our tablets? Ask Samsung.

I have seen a few people say they have noticed slow charging with the Nexus 7. I'm not sure if the following means anything, but here is what I have noticed between the two N7's that I have and the one that my brother owns.
My brothers 16GB N7 (purchased 2-3 weeks ago) is extremely slow charging from both the wall and USB power sources Using the OEM cable, and after market, and when trying an iPad wall adapter. No matter what, it's just SLOW.
I purchased a 32GB about a week ago, and have noticed that, while still slow compared to my iPad 3 and iPhone 5, it charges faster than my brothers, so we set them side by side @ 40% and while I should have recorded the time, mine had reached 87 % while his was only at 80%.
A few days ago I realized that while ai sit on the train so much that having celular would probably be a better idea and I missed having it on the iPad which I had sold to buy the N7(aside from missing LTE I do not regret this move one bit). So I sold the 32GB to a friend and bought the 32 W/ 3G. This one though charges noticeably faster than even the last 32GB did. I am running the same kernel and a CM branded ROM, but it doesn't seem to suffer from the slow charging as much, still not iPad3 recharge speed though.
I am wondering if Google/ASUS are changing firmware on different revisions to fix this issue as I see no other reason for the charging speeds to be so different.
** On a side note while my brothers 16GB had no screen lift, my 32GB had lift. I opened it and found that, while face down on the table, the top right screw was 2/3 unscrewed and while tightening it I saw that the screw about an inch or so down from it for the screen was missing all together. Luckily my 3G doesn't have any lift, at least not that I have noticed yet.
I think I saw something straight from a google higher up mentioned to developers that a different power controller would be implemented as a hardware revision on later n7s. I would assume most if not all 3g models are using this new power controller.

My 3G 32GB charges pretty fast .. quicker than the 16GB that is for sure .
i had a seven that was replaced recently, 16gb, because it stopped charging. that seven always charged slow. the replacement seven, also 16gb, charges much faster than the older one. same charger/usb used on both devices.
The stock Asus charger has always been slow to charge my C9O 16GB N7. Using my TouchPad charger instead the N7 charges significantly faster. The Asus charger has since been relegated to charging phones.

My nexus 7 used to charge fairly quickly, around 90 minutes from zero to full. But recently I plugged it in and after an hour it was not charging at all. I unplugged the cable and it looked a little charred, and the socket itself had a slight burning smell. I've used the official charger only, but I think something has gone wrong, it note takes hours to reach a full charge, so think I need to return mine.
Sent from my Galaxy Nexus
Mine was connected to the socket about eight hours while I was asleep since yesterday (when I got it). It charged only from 25% to about 80%, though I remember the screen was lit up, and I turned it off some time during the night.
When I was in stock ROM it was fast but now on paranoid android 2.54 it's very slow.....

My C80K is picky about what chargers I use with it. It's fine and quick with the Asus charger that came with it, and the Samsung charger that came with my phone, but doesn't charge very quickly on my mom's Motorola charger (still reasonable though) and takes 10+ hours to charge fully on a generic charger I bought at Five Below (which is ridiculous). It charges off the USB ports on my computer slower than the Asus and Samsung chargers. I still use the generic charger for my phone though, and it works fine.
Please, define slow in minutes/hours and if not using the original Asus charger, also mention the output current, which the 3rd party gives. Otherwise it just talking . Asus charher is 10W, whereas a phone charger is usually below 5W - it is normal to charge slow.

I have noticed that charging is slow with mine (32gb model). It will normally take around 6-7 hours from around 10% battery life to be fully recharged. I have also noticed that the device will not charge when in graphically intensive apps e.g games. In fact, it will slowly decrease.

I got mine from digigood, so it came with an original US charger (I'm in UK) and digigood supplied a universal microUSB charger.
I've not timed it, but a full charge from empty takes approx. 3 and a half to 4 hours. Someone in this thread said theirs took 90 minutes... I also have a blackberry charger which is micro usb, and I have an OEM galaxy s3 charger too. I think I'll time each from empty and see what happens.

I'm on my 3rd n7 (got 16gb at release, then 32 when it came out, then got a replacement for that as the screen had a few dead pixels). The 16gb is very picky about the charging cable, using the stock cable it charges quite quick (maybe slightly slower than the 32) but using an extension with the stock cable the power actually falls very very slowly, and an overnight charge only adds about 50%
The 32 however, is lightning fast, a full charge only takes about 3hours. I can put it on charge for 20 minutes and get about 20-30% charge.

Just curious how many days your getting out of the battery for those running Cyanogenmod which seems to already have a very good battery. I'm a sucker for things that can keep me going, and I've pretty much made the decision to grab the battery with the nice case offered.
I have tried already searching Google and the long Zerolemon battery thread but couldn't find anything relevant.
Been using this 9300 battery for a few weeks. I do use my Bluetooth to a small speaker at work for about 9 hours a day and I am still getting 2 full days. That is as long as I fully charge it. If I unplug as soon as my indicator says 100% then it drains pretty fast. Without using the Bluetooth for that time period I am curious how many days it will go. I either use cyanogenMod or aosb probam

"
Shift Tools" comes with the Cyanide L Rom and Shift Kernel by Brett Rogers (rogersb11).
For a SUPER FAST charge use 2.0 car or wall charger and usb charging cable (not a data cable).
Open system settings, scroll down to shift tools, open shift tools, swipe over to "charge control", go down the list turning everyrhing all the way up make sure you scroll to the very bottom and turn on " ignore 100mA safety margin and "ignore unstable power detection!!
Then turn display brightness all the way down, put phone into airplane mode or turn off phone.
I only use this when I need a quick charge and do not leave this charging past 100%... enjoy.
