[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.

[REQ] SpeedUp charging process

Hi people... i think that Samsung has got a little of troubles of making batteries and charging philosophies.
I has got two devices that are the last technology from samsung, the nexus s and the galaxy s2 right now.
The nexus s has got a very strange trouble (until now not fixed) that battery never reach full 100% state in charging. And much very very long charging time.
The Galaxy S2 reach 100% but takes too much time to charge. It's possibile that never one has think about modifying this?
Where we can start to mod this ? Inside the kernel? Inside bootloader?
I think it's not only a mine trouble

i think its the battery charger not the phone, which makes it so slow

5 views, 4 replies, justshows how desperately we want this...

Mine finishes very quickly. about 1-2 hours when it's at 25 percent. And you cant fix charging. Remember that it is a big battery.

Ever tried using an adaptor for a device that has a lower rating than the adaptor? Ever heard that pop and the smell that follows?
Learn to be patient. Last thing you need is for the battery to blow up and destroy your phone.
protip: turn off your phone while you're charging with AC and not USB.
it could be your USB (and by extension, your PC) is not providing enough power to the USB ports. It happens.
My phone charges in 4 hours with AC when the phone is off. 5 when on.
6 hours on USB, phone off. 8 phone on.

It can be "fixed" in the kernel.
Samsung made it charge slower so that it charges better.
Faster charging = more heat = more dissipation, and potentially other problems.

Even though its a safety feature, its ridiculously slow. Phones takes AGES for a full charge.

these new phone are strange
my old i8910 HD charges full in like 30 min
and stays without a charge for 3+ days

Mine charges slower than htc but no too slow.. I'd say 2.5 hours full charge

too much slowly. I prefer changing battery every 2 years but have a more speedy charging, specially when i'm in middle of day (usually i charge it in the night, but sometimes can't last the entire day)

Do you guys not get more than 3-4 hours of sleep?
Do you guys exhaust the battery to the point where the phone turns itself off before plugging it in?
Can you not plug your phone in before you go to bed?
I always plug my phone in before I go to bed (usually with 10-20% remaining) and I don't remember a time where I wake up in the morning and the phone isn't 100%.
I'm not trying to be cynical...just curious what other people's routines are when 3-4 hours to charge a phone becomes an issue.
A complaint like this wouldn't even cross my mind.

I need a faster charge too. Not because I'm impatient but because the phone can use more current then it can charge, especially during car navigation.

Well, the issue here is obvioisly not when sleeping (and yes I slept 3 hrs last noght and got a full charge...bit when on car or @ work, lunch time etc...those little precious weird moments u get in a daily basis when u arent using ur phone and got a charger at hand....maybe it would be possible to make an app which would allow toggling fast charging or slow charging, that way we could have both....fast ( on the run) and slow (night) modes....that would be really nice......but wait....winmo had this remember?

Total Charge timing of nexus 7

Yeah 4 hours here too. At least.

about 2-3 hours here
dont mind though as ive been out using heavy for whole days and still got back home at midnight with 65% left luv the nexus battery

Id love to hear how some claim to have fully charged their Nexus in 2 to 3 hours, it takes me 4 hours minimum to fully charge it from around 6%, i haven't let it drop beyond that yet.

I'm not 100% sure on the time but about 1-2 hours, but then again the lowest I've ever had it is 13%. I tend to keep it plugged in if I'm going to be doing something battery intensive like play games or a lot of web browsing, and tend to turn it off over night and pick up notifications on my phone as it doesn't give off as much light from the back light as my N7.
I love the battery life on the N7 as it could probably go for at least a day and a half on battery if I left it on all the time and used flight mode over night, but I don't want to kill the battery and have to mess around inside it to change the battery.

It depends on what ac adapter you use, and how much current it puts out. I originally used my incredible s charger and out took forever
With the Asus OEM one it takes around 3 hours from around 0-5%

This here. It is horses for courses.
As for the debate on charging times. 3-4 hours is the norm for most of us. Given different tolerances in both the charger and battery some migh be on the lower end of the scale and some higher.
Just remember to use the OEM Asus adapter as it puts out 2amp at 5v. (Or a 2a equivalent) .
Most phone chargers and USB ports on comps/Xbox etc only output 500ma (.5 amp). You can use them but it will take a good ten hours to charge with them.

Exynos variant does not support fast charging while Qualcomm does...

35 hours or more of total battery life with 6 1/2 to 7 hours of screen time. I play a lot of intense games so my screen time is lower, but I've easily been able to get 5 1/2 of screen time out of this thing playing Galaxy on Fire 2 and it's like one of the most demanding mobile games available.

I was using previous generation of 10.1 on almost minimum brightness, and was getting more than 10h of screen time. Yes, I've been using it indoors mostly, and my eyes weren't asking for more. I am getting new 10.1 in couple of days, and hope to have similar SoT...

the exnyos does have a full powered charge at up to 80% then trickles to 100%. it takes mine about 4-5 hours to go 0-100. it doesn't use qualcomms quick charge tech, but it doesn't trickle the whole way. if it takes 7 hrs then the charger or cable could be bad or the tablet may not be telling the charger to send 2amps.

It's pretty slow. Almost 30% slower than the N10.1-12 a lot of us came from. It's the move from Samsung's proprietary 30-pin connector to standard microUSB. The N10 using a pogo pin charger (vs. its standard microUSB) is about 30-40% faster than what's shown below.

that article was what concerned me before i bought the tablet, but i went ahead and got it anyway. the only time that mine had actually nearly taken that long was on the first few charges. sometimes it would be stuck at trickle and wouldn't pull the full power (i actually only get an average of 1.6A from the stock charger and cable - I've never verified the volts. i could stick it on my killawatt and see what it pulls. after those few quirks i don't see charge times as long as anand has reported. it's always that last 80% that's a killer. it seem to take from 1.5-2hrs depending. i can go from 37% to 80% in 2hrs then i have to wait nearly as long for the last 20%. i think it's a battery saving technique that samsung is using. toyota's reports showed that charging the battery to 80% capacity extened the life. on my 700t there's a battery saving option that won't charge the battery over 80%.

USB 3.0 doesn't impact charging time, at least not yet. And the S-800 version of the N10.1-14 does use the same SoC as the N3 and someone here with a SM-P605 reported getting a full charge in about 5 hours and 80% in 3.
Charging is an interesting story on the Note 3, but primarily because of what doesn’t change. The Note 3 continues to use Samsung’s tablet charging specification and charger, which has 2 amps of maximum output. The Note 3 draws 2 amps over a considerable amount of the charging curve, like other Samsung devices (in the linear part of the charge curve). USB 3.0 doesn’t change things up here quite yet with the new supported charge voltages that are coming eventually with the power delivery specification.
The Note 3 does charge faster overall compared to the SGS4 however thanks in part to the new PMIC (PM8941) which is part of the overall 8974 platform story.

lol, that's actually a feature that Donald Trump insisted be included in all white and black Notes to remind people they aren't part of the exclusive 1% who actually have solid gold Notes. Interestingly the solid gold Note consistently shows 1%.

See this is the odd thing - I had this tablet a month ago but got it exchanged because I found a cheaper one anyways on that tablet I am positive I was getting 6hrs screen time which was some youtube videos but majority was browsing the internet and that was it.
However on this new one I just got 9hrs30mins and that was with watching a 2hr movie streaming online, about 2hrs worth of streaming tv shows, loads of web browsing and also a little bit of Youtube...Personally I think this is awesome screen time (Mind you it's my first tablet so nothing to compare to but still). I am very happy with charge (5hrs) and battery drain on this tablet - very nice indeed.
Would love to squeeze 11 hours out of this like someone had in the earlier posts but that seems a tad difficult considering I already have brightness pretty low and all pointless apps disabled.
