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.

bad battery
I have been having really bad battery on this yesterday left it a home with a full charge at 9.0am and today at 7.30am had 11% it had screen always off and it had not been touched thinking of send it a off to LG to be looked at

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 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.

We all know that charging with the stock charger is very very slow so i was wondering if i can use a charger that outputs A) 5.2V/2.4A B) 5.1V/2.1A C) 5.0V/1.2A these are all charger that i have which one is the best to use without damaging the battery ????
none, as long as the charger your using isnt weaker than the stock charger, it'll make no difference. Having a 2amp charger might produce more current, but the phones going to accept only what its programmed for, which is what the stock charger outputs.
Its safest to use the stock charger with the stock cable, and if your phones fairly new, don't worry, charging speeds up after a week or two.

Phone has power supply control chip that limits the maximum charging current (1A in case of HTC One). Unlike fast USB charging maximum charging current is not something that is possible to be changed from any software.
as the title says,
How long does it take to fully charge your Z1 from 0%?
mine takes 2.5 - 3 hours, I do think that this is quite a lot although it is faster than my old xperia S which took ~2 hours with almost half the battery size. But I was expecting more improvement from the promised 70% with quick charge 2.0. This is around ~40% improvement, or am I missing something?
From 5% left charge to full. Three hours

I don't think Quick Charge 2.0 adapters are out till early 2014. Even if they are, the one that came with my Z1 doesn't support it. Only Quick Charge 1. You can tell because the output is listed on the adapter (mine is 1500 mA).
Quick Charge 1 works on .7 to 2.5 A. Quick Charge 2 is 4+ A. (Standard USB 2.0 port will provide 500 mA while USB 3.0 will provide 900 mA).
So my 1.5 Amp Z1 charger isn't even at the top end of Quick Charge 1. With that said, I haven't tested a full charge. But if plugged into a USB 2.0 port, it barely charges while phone is on (few percent an hour maybe).

what you said does really make sense because quick charge 1.0 promise ~40% faster charge which I reported in my first post (+1 for that). Now is there any way to check whether the Z1 support quick charge 2.0? I know the chip S800 does, but what about the battery software or other internals (I am not really expert in this area). if it does then when new adapters are released with output more than 1500mA we will get faster charge time. I have my nexus 7 charger which says 2000mA, would this make difference and would it hurt the Z1 battery if I used it?
One last thing, if the output is 3000mA does that mean half the charging time? or there are other things to take into account?

All Snapdragon 800 chips have the QC2.0 circuit so we're good. Just have to wait for chargers.
I'm not an electrical engineer (studied mechanical) so I can't comment on things like losses within the charging process and all that technical stuff. However you have the concept right and in general that should be true. 3A charging a phone should charge it twice as fast as 1.5A

Other charge are made from 30-40% to 100%.
Mine takes an average of 2/3 hours to charge from 5% to 100%, I do however only use 1 Amp charges which are old phone chargers.

The iPhone 5 has a battery half the size of this... I personally take about 2 -3 hours to fully charge the phone using the Sony provided charger!
Started Charging at 1:06 am - Battery was fully discharged.
1:23am Put Phone on - Battery at 11%
2:31am Put screen on - Battery at 52%
3:06am : Put screen on - battery at 73%
4:19am Put screen on - battery at 99%
4:26am Put screen on - Battery fully Charged .
I think the problem with the provided charger where the output is only 1500mA. the SGS4 with sd600 (does not support quick charge 2.0) comes with charger with output 2000mA which I tried with my Z1 and slightly improved the charging time. what we discussed earlier about early 2014 release of the quick charge 2.0 compatible chargers is the solution, I found couple of sources that confirm this. so we hope that better chargers to be released soon with 3000mA + ouput which would reduce the charging to to less than half.
it took 1 hour 40 min to go from 20% to 100%, I'm using the charging dock that came with the phone.

2600/800 = 3.25 or 3 hours and 15 minutes.
Today, I don't think this phone can accept anything like 2A charger (don't really know) . Else, it would take 1.3h or 1 hour and 18 minutes.
Get a 2A charger, disconnect every electrical equipment and charge your phone.

Yes Quickcharging will improve charging time. But as stated above it also depends if you use your phone in the meantime and its idel consumption. The fastest charging time will be if you turn of your phone and then start charging.

"When using ??"
What do you mean by ??
Ideally to charge the note 8 fastest you'd either want to use a qualcomm quickcharge 3.0 compatible charger or a USB type C charger with Power delivery (USB-PD), along with a decent cable such as the one included. The Note 8 will say Fast Charging on the lock screen if it's being used with an optimal or near optimal charger/cable combination.
It doesn't fast charge while the screen is on, it barely charges at all.
The output is not far off what the input is when you are using the phone and fast charging.
(Price you pay for a big screen)
If you were using a regular charger and using the phone your phone wouldn't be charging at all it would still discharge.
Simple solution just don't use your phone for half hour !
Charges to full in 1 hour and a half without the screen on
Or charge it overnight? That's what I do and it easily lasts until the next night
I have several samsung fast chargers, but only some of them would work on fast charge.
I realised it was a problem with the cable, so I swapped them to the original Samsung cable and all the fast chargers work on fast charge now.
So check the cables ....
