Hello everyone. My Tab takes about 8 hours and 20 minutes to recharge itself, is that normal?!!
I have the official cable and a generic 5v-2amp wall charger.
Do I have to get the official wall charger and where can I find it, coz I don't want to spend another $20 while I already have the cable...
8 hours is a really really long time ? ? i think you need to buy a original charger .. where to find : nearest Samsung Service center tho .
Chargers go bad. My stock charger just died when I went to the desert with no chance of getting another charger.

3-4 hours from 10% to full charge on original charger.....However if you have electronics knowledge you can patch your non orig charger so that it will charge your tab faster. http://forum.xda-developers.com/showthread.php?t=845844&page=3
So, I guess I'll have to get the original charger. I found a very good deal... I think:

lol . and how could you charge your tab in the desert though ? plug it into some sans ?
If you go to the desert on foot no way to charge....
But if via off roader/4 wheel drive then via the cigar lighter using the adaptor I linked to earlier
yeah get the original charger, mine takes like 3-4hrs if that...
mine is original samsung, 5v 2amp. Take about 8 hours to fully charge the battery. What about your charger voltage rating?

The generic one is 5v~2Amp. Why are there different reports on that? Is there any setting or may be under-volting settings that we need to enable for this?

Well, I have a SGT7 Plus (P6200) and I usually charge it at 20% or lower.
It takes about 3-4 hours to full recharge while it's off
you do realised this was a June 2011 thread?
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.

Change your charger
Actually its not the Phone's issue but the Chargers'
I am using my Lumia's charger and phone gets charged in a hour from 0-100%
I will have an answer for this in a few days.
Theoritically it should take 225mins to charger from 0-100% with stock charger..
Anyone knows maximum charging rate?
Just did a full charge (0-100%) without the OS running. Took 2 hours. I'm using Anker Power IQ 40W 5-port desktop charger and Moto's USB cable.
Remember, quality of the cable (as well as the charger) directly affects charge time. So try to use official or high quality cable and charger

Mine also takes almost 3 hours. That is because they have given a 500mAmp charger . I am using my iPad charger block rated at 2.1A and it charged from 25% to 100% in 70 minutes
Yep,
Use a 2 Amp charger and you will get full charge in 1.5 hours.
Is it just my device or does this thing charge super slow? I can't even get a full charge in a hour and a half and the battery is only 410mah.
Do you use original AC Adapter? I use another one now and I can get it charged in 45 minutes, which is ok to me.

I would advise against doing this. You will shorten the battery life due to the extra heat produced. Always use a lower amp charger unless you are in a rush!

Can someone tell me how long the actual charging time exactly takes ?
I use the original charger that comes with the device and it takes about 3 to 4 hours to fully charge the watch.
I find that quite long as I read the comments here.
The first tames it takes only 1,5 hours to charge it but all the other times it goes real slow.
A factory reset didn't help to resolve this issue.
Thanks.
As far as i remember battery have a capacity 410mAh, original charger have power output 700mAh, so charging time should be about 40-45 minutes max.
Change usb cable, if it doesn't help change charger (but it should have power output >700mAh)
PS. AFAIK using charger with power output >700mAh is harmless because watch limits charging current by itself.
Measuring charging time is best indicator.
Charging with 2.0A adapter will not increase the charging speed - the watchregulates the charging current, it will not just blindy "connect" the charger to the battery (in fact, I can't think of any piece of electronics that would have the charging logic in the adapter nowadays).
I had no problems with any chargers, not even with USB charging - the battery is very small, so unless you have a charger that can't put even 500mA you should have no problem.
I've seen an issue where the watch was "charging" constantly and ended with 85% and wouldn't charge anymore - reboot fixed that and it showed 100%.
I was thinking that your charge takes so long because you could have some process draining your battery in the meanwhile (that starts when you connect your phone, like a tasker thing or smt). Newbie thoughts so correct me if this is impossible
I could try to do a factory reset and see after that if it charges much faster then now.
For the moment i have a few apps on the watch, i do not know if it matters or not for to influence the charging time.
It's weird that we do not have the ability to load the watch while it is off.
From the moment that i put it on the charger it turns on automatically !
hello my friends.
the charging dock is limited to 0.85 A (850mA)
It makes not more sense to use a Adapter with 2.0 A Output. It won't charge faster.
Look if every pin on your dock is ok.
also the connection pin on your watch.
Try to clean a little bit with high percentage alcohol.
best regards
Problem solved by using another USB cable.
Now fully charged in 1,5 till 2 hours.
I haven't measured the charging time of my watch but it looks to me pretty fast. I guess with original charger 30 mins - 45 max, not a min more.
Don't sweat the amps

Hi,
that statement isn't particularly correct. The charging system in the watch (as with any LiIon battery) will draw as much current as is "good for it" and no more.
Just because a charger offers 2A doesn't mean that this is the amount of current flowing through the charger / battery!
I'm using the "fast charger" that comes with the phone, but it seem to charge slower than I predicted. It says 1 hour until full charge when they phone is at 55%.
Is this right?
did you use the cable that come with the phone?
not all microusb cable can do fast charge.

Yes. I'm using everthing that comes with it.
The next question is.... were you messing with the phone while it gave you that estimated 1 hour left to fully charged? If you have the screen on and doing a lot of crap with it, of course it will take longer (this may be obvious to some, I'm not trying to insult you if you didn't know this, just stating the fact)
My experience with it went like this yesterday - note that I haven't even unpacked the factory charger, was using the Motorola Turbo Charger for this "experiment"
0% (phone died over night off charger to make this test)
30 mins on Turbo Charger - 45%
1 hour on Turbo Charger - 85%
Had to take it off to go to work, but those are some great numbers for a charger not necessarily designed for this phone, but the device was in Fast Charging mode the whole time, of course, so it was comparative
Is there some way to turn on fast charge? Because 6hours to fully charge or even charge a lot I don't have.

Use the fast charger that came with it or the Turbo Charger and it comes on automatically, 6 hours was with me using wireless charging which is always going to be slower than any wired 2+ amp charger will do

Lol I plugged into the the stock charger from the box and it said 6hrs to charge (from 0) switched outlet just incase that outlet was wonky but same result. The I said screw it and just figured I use to wireless charger so at least the phone would be near me, low and behold it says 3hrs (from 0). So apparently wireless is the way to go.

You must have had something else going on with the phone for it to say 6 hours on the factory charger....... I don't remember what mine said because I plugged it in, powered it on, and started watching the clock in the kitchen, turning on the phone screen only to check battery levels at those specific intervals I stated! I didn't even touch the device to start anything when I started this experiment, so it wasn't running any apps other than Android system level stuff, but no, wireless definitely isn't going to be faster, despite what the estimated timer said on the phone!

Well it's charging super quick compared to that factory charger. On the factory charger (plugged in right after phone died) went from 0 to 5 percent in about 25 minutes. on the wireless charger right now its gone from 5 to 16 in under 20 minutes. more than twice as fast.
Aslo, I am using the new Samsung wireless charger that is supposed to support fast charging.
**EDIT**
It charges even faster if I plug it directly into the cable for the wireless charger. Now it says 1hr29mn instead of 2hrs.

Make sure the cable is plugged all the way in to the charging brick. If it's not plugged in all the way, even a few mm, it will charge much slower.
