[Q] NY Tabs sluggish to recharge?

One recent review of a NY Tab said it was taking a very very long time to recharge....
http://www.pcworld.com/article/229763/samsung_galaxy_tab_101_wifi_a_worthy_rival_to_the_ipad_2.html
from the article: "Another thing I noticed in my casual testing: The 7000-mAh battery took inordinately long to charge. After 2 hours plugged in, my test unit had reached only about 30 percent charged. The battery is rated for up to 9 hours of use."
anyone heard of this, or does someone who actually has a NY model have anything to say about that?

The charging current probably is written on the charger, anyone can take a look?
If what they said is true, then the charger is charging at about 1A and it should take about 7 hours to fully charge...
I'm not sure i want a Galaxy tab 10.1 anymore.
EDIT:
Is this the charger that is included? http://www.samsung.com/us/mobile/cell-phones-accessories/ETA-P10JBEGSTA-reviews
Samsung site says it charges at 2A, so the 7000mah battery should be fully charged in about 3,5 hours.

This is true, it charges twice as slow as my Xoom maybe slower. and it seems to drain faster also(during use anyways) and my Xoom is OC'd @ 1700.

This was the only review I've read so far that mentioned slow charging. I do know when I had a Xoom it seemed to charge fully in @ an hour or so. I'm hoping that its charging time is not a big problem for the Tabs, since I'm thinking of getting one.

Mine charges slow over USB, but with the wall charger, it's at least 30%/hour

I noticed that the io tab took a long time its first few charges. Now it doesn't take too long to charge. Few hours at most.

Same here the first one took hours and now it's a few. The charge really does last after that.

I checked the compatibility list... All of the 10.1 are compatible with that charger.
Found it at Amazon for 32 and change...
http://www.amazon.com/Samsung-Galaxy-Detachable-Charger-ETA-P10JBEGSTA/dp/B004CGHDEO
I will be buying one or two of these depending on the one that ships with the tablet. Can we get confirmation on the one that is included?

I'm recharging mine right now from a complete discharge.
Exactly 2 hours in and my battery is at 44%.
Do probably about 4 hours for a full charge.
I'm using the OEM wall charger.

If you guys are having issues the quickest way to charge something is by turning it completely off. im sure that will speed up the charge a lot at least by 50%...also the first few charges are the ones that typically take longer. Eventually the battery will charge faster.

6 hours to recharge?

I recharged my Galaxy Tab 10.1 yesterday from a 15% remaining charge.
I powered it off and used the wall charger. It took almost 6 hours to charge to 100%!
Is this normal or is there something wrong with the battery?
Thanks!

Mine was slow at first too. But now seems to have gotten quicker.

What is the rating on the charger that comes with the unit?

The rating is 5V - 2A

Yep, noticed it took about 3 hrs to go 40% charging. Not sure why there is such a drastic difference from the Xoom which could charge from 10% to full in little over an hour with similar drain to GT.

Can you please quantify what quicker means?

We have a rather large battery in the device, while I agree 6 hours is abit much, it should be quicker at 2 amps.
On the other hand, I sit in on the charger at night before I go to bed. I am definately a heavy user as well, and the battery lasts me all day with atleast 30 to 40% left over by bed time (this includes a 1.5 hour commute each direction using Waze, the GPS, and wifi tethered to my phone, 2 gmail accounts polling every 15 min, web surfing throughout the day, and playing games during my morning and afternoon constitutions .. I know.. too much info)..
So I can live with a longer charge time, at least for now..

I charged my GT Tab completely before using it the first time. Then I drained it down to about 9%. I timed my first full charge from 9% to 100%, it took exactly 6 hours and 4 min. My Xoom charged in half the time. I am hoping it gets better like I have heard from different people.

i believe the xoom's charger is 16watts or more. i can't really remember, but it's got the highest rated charger b/t the xoom, tf, and gt10.1.

I think that's just wishful thinking on their part. How does a battery suddenly learn to charge itself faster. You make it sound like the battery is a muscle you can work out. The thing takes forever to charge but it also has excellent battery life. So as long as you don't find yourself in a hurry to travel without time to charge the battery should last you almost all day.

I charged the device fully before use. Used it down to 10%, plugged it in and charged to full powered off. This took around 6 hours. The second time I charged it from around 14-15% It took about 4 hours. I have charged it twice more since from almost zero, and it's taking about two hours.

Remember the math:
7000 mAh battery
2000 mAh charger
That means from drain to full if the screen is off, about 3-4 hours. If you have the screen or device on and it's doing anything, it's using some of that incoming charge, so will increase to 4, 5, 6 or more hours to fully charge.
Gets even worse if using an aftermarket charger, say a 800 mah or 1000 mah charger like the iPhone or Kindle charger...can then take 10-14 hours to fully charge, hehe.
It's funny how people say it charges quicker after a while, when that's not logical, you just don't notice it as much going from 65% to 100% as you noticed when it went from 15% to 100% the first time, hehe

Smaller battery=shorter charge, a 2 gallon gas tank is quick to charge too, hehe.... kidding.
But seriously, Samsung is bad with their charging. My Samsung Infuse and my Galaxy tab both take forever to charge.

Did I read it correctly that if recharged from almost 0 (e.g. <5%?), it takes only 2 hours to go to 100%? This seems counter intuitive.

i think what happens is that as the battery calibration gets more accurate it finds where to quick charge and where to trickle in the appropriate levels.

Average charge time?

How long is it taking you guys to charge your N7? At first I had the sleep of death and once it finally turned on after a slight charge, it stays at charging 0% for quite some time now. But before that, it always seemed to slow charge.

No idea. I plug it in when I go to bed and it's good to go the next day...lasts me the whole day. I also don't know how many licks it takes to get to the Tootsie Roll center of a Tootsie Pop.

At I/O they said the tablet takes about 3 hours to charge from 0-100% but it may be faster. Whenever I get the 15% alert I throw it on the charger for about an hour and it's past 50%

charge times will vary depending on the charger as well, best charge time will occur from the wall charger that came with it, USB trickle charge will take a month of sundays :laugh:
that is of course unless you have a magical USB controller that outputs 2A from each port (highly unlikely)

I wonder if its something wrong with my battery. Been on charger for more than three hours and nowhere near 100%. It was at maybe 48%. Drainage seems reasonable..its just the charge seems rather long to reach full charge. This is all from using the stock charger too...

Typically 3 to 4 hours for me using OEM charger
Via my HTC Rezound

Between 2-3 hours on charger, around 7-9 hours on usb.

My battery app says 3 hours and 40 minutes on average. That includes charge times when I am using it at the same time so I guess about 3 hours.

I don't know what happened, but with me, when I first got it it was 3 hours on the dot to a full charge. Then one day it said it needed to be plugged in to charge getting below 14%. Then I plugged it in and got the sleep of death, and plugged it in the wall and the battery icon came up, then I turned it on. Now it's been charging for about 6 hours and its only 85% :crying:

Mines generally around 40% at the end of the day, it takes less than 2 hours to get to fully charged.

Mine takes about 3.5 hours but I noticed my 10 foot micro USB cable doesn't charge fast at all. Takes about 12 hours on my 10 foot cable

Yeah I'm with the rest, mine's in the 2.5 - 3.5 range. But as stated, which charger you use makes a huge difference. Charging off the computer (USB to PC) is waaaay slow. Using the OEM wall-charger is what should give you 2.5 - 3.5.

3-4 hours for me depending on what percent I wait till, usually 5-15% battery, haven't tried with anything other than the OEM charger though.

From about 10% ie when the warning to charge came up, to 100%, took mine about 2-3 hours only last night using the supplied charger. Much longer on USB, haven't timed that.

Should I get mine exchanged ? I'm still within the 14 day policy of Mac mall. Its been an hour and its only 14%. Usually it takes 3-4+ to charge fully.

Make sure you're using the supplied charger. I believe the ones for smartphones charge at a different rate? I made the same mistake when I first got my Nexus 7 by charging it with my SGSII charger. It was VERY slow. Then I switched back to the supplied charger and everything was normal.

Usually takes me just 2 hours, and it is full. I usually start charging at around 15%. Using OEM Charger too. :good:

I used my Gnote charger but left it overnight (about 5hrs). I'd say that normally it takes around 3 hours. The battery life is awesome I have to say.

I found this while searching for an answer, my Nexus has been taking 12-15 hours to charge fully, using the factory charger. I also tried my powered USB hub (using a charging port, rated at 1.5 amp), and my Galaxy Nexus charger, same thing. Called Google today and they said it's the device, and I need to return it. Luckily I bought it locally, so I can just exchange it at the store.

Why does this charge so SLOW?

I am completely satisfied with my nexus 7 but it seems to be charging ridiculously slow. So slowly that even browsing with my screen on low, my battery still goes down while its plugged in. And a 1 hour charge with my nexus off only charges it like 20 percent or less while my samsung galaxy player charges 65 percent. I have tried 2 different USB cables and chargers.

considering theres much less voltage going through when using the usb(not wall charger) to charge, its normal for it to charge slow. and normal for it to lose battery % while charging it via usb and using the device.

Be careful as the faster a battery charges the hotter it gets and the hotter it gets the faster it's performance and life decrease (all batteries life and charge levels will slowly decrease over time and after soo many charge cycles as parts of it very slowly kinda burn out and are unusable). Also why even fast chargers SHOULD slow down when you hit roughly 90 - 95% as it is not good to cram power that fast in to lithium ion when close to full as this causes the loss of parts of the battery more quickly. Usually it can be apps that can slow things down as well. like my boss kept complaining his phone are 3 batteries a day until a week later I convinced him to get rid of unneeded apps and low and behold it came right back. This is due to apps requesting what's called a wake lock basically telling the device to not go to sleep. This is needed to do syncs, scans and the like, but poorly written apps can juggle wake lock poorly causing bad battery usage when they don't need to.
My tablet charges in roughly 2.5 hours from dead to full using stock charger which is GREAT for a 4000 maH battery.
I also highly recommend turning the OS off and charging via charge only screen (where you see only battery graphic filling up) that would not involve any apps messing with the device while charging.
Also not good to leave device on charger longer than roughly 30 min past full as this could then have charger throttle between fast and slow charge over time (usually due to imperceptible power fluctuations tricking the circuits in the charger to reset and it takes it a sec to realize the battery charge level and adjust back) while battery is full which is very bad to have it in fast charge when it's full as stated (the charger not talking of what some folks call a fast charge mode on some devices (usually used in some way to speed up charging when using a computer USB port)) and is why even manufacturers will warn you if this sort of thing (that is if you read caution statements or manuals)

Very true depends on how hard you are running the device. Streaming movies in this mode most likely you will see a loss while simply checking news feeds or light internet browsing it still gains percentage.

I think it charges normally. I come from an iPad 3, which take 6.5hours hours to charge from 0 to 100%. I'm satisfied with 3.5 hours with the N7.

My Nexus 7 charges from dead to 100% in about 3 hours. That's not slow at all.

normal charge time? after 2hrs, 35%--->98%

is that normal?
i went from around 35% to 98% in less than 2hours charging via NON stock cable/non stock adapter
9:43am - 11:35am to be exact

My phone takes about 2 - 2.5 hours to charge from 5% to 100% so yes, that's likely normal more or less.

From 0-10% takes 3 hours roughly. You're okay.

you mean 100? lol

Depends on the charger. I think the nexus 4 ships with a 1-amp charger. Quick chargers will charge faster (usually 2-amp or higher), but are not good for your battery's life expectancy.

You are lucky!
It takes my phone about 8.5 hours to go from 10% to 100% with the stock 1.2A charger....
I suspect a faulty USB connector on the phone.

It takes me 3 hours to go from 0 – 100. I am not using the stock charger. I am using the old charger from my g2. I guess I should try using the stock charger.
Sent from my Nexus 4 using xda app-developers app

The majority of your phones charge takes place from ~80-100%.
0 to ~80% should be a "quick charge" that will take much less time to complete.
Also, the charger being more than the stock Amps shouldn't affect the time.
Less, yes. More, no.
The phone will only accept a maximum charge rate that the manufacturers have deemed "acceptable" or "safe" for the device.

hi,
perhaps slightly off-topic, but still about the charger...
So I have the original LG nexus 4 charger, and I also have charger from my samsung tablet. One thing I noticed is that my nexus would charge from any of these two, however the tablet would charge only from its original charger (looks like it requires more output power??). Now my question is: is it ok to charge Nexus from the (more powerful) samsung tablet charger?? Or is it going to affect in any way the battery lifetime, and i should use original charger for each device?
