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.

I have NEVER EVER had a phone that took so LONG to charge up!
Is it just mine? Maybe it's defective? What on earth did they do?!
Takes probably like HOURS to get to 100% with the screen, bt,wifi OFF!
And what's crazy is that after the phone says it's fully charged I unplug and the battery meter drops to 96-97%%. THAN it takes more time to get to 100% again.
If I didn't like this phone so much I take it back so fast!
Does you phone take really long to fully charge?
The charger is slower. This helps extend battery life typically.

Really? Didn't know that. Can I get a faster charger then? I'd rather my batter charged in 20 min and have to get a new battery every couple months than have to wait nearly four hours.
Other than that I'm loving this thing.
Do you not charge it when you goto bed? When I wake up mine is fully charged. I don't check to make sure its 97% or anything like that, but when I goto bed its been known to have around 70%.
Of course mine is coming off the charger at 6am and I normally goto bed around 10:30-11:00pm.
As for charging a battery for 20minutes and having it full I've never seen that in any phone I've ever owned. You could buy a quick charging car plug, but personally I wouldn't recommend it for charging all the time.

Of course I do. But I use my phone way more than most people. So I have to charge at least once during the day. And that takes forever. I'm going to have to buy and extra battery with external battery charger to just SWAP!
Glad this is "normal" thought my phone was defective.

Well I'm coming from a old phone that would charge to full in about an hour and be functional for 3 days. I didn't expect that with this phone (with the sweet screen and processor) but I am barely making 24 hours. I don't have GPS or Wifi on all the time and keep my screen on a low brightness setting. I AM playing around with it all the damn time though.
Anyway a normal charge at night works most of the time but it's good to know I can get a faster charger for the times when I need the power right away.
Also, any way to see the battery usage for the life of the device?
That's a smart phone for you. Never had a smart phone that would last more than 2 days tops, and that's with light use. But with moderate to heavy use,a day is it, maybe even a quick charge in the afternoon depending on how heavy the use.

If the Nokia e72 is considered a smartphone that phone lasted for days!
I know it has a small screen and all that but still, the battery was AMAZING!
Is it just me, or does this bad boy take all day to charge? The transformer only outputs like 1.2amps. I've only gone from 45% to 77% in like 4 or 5 hours. It's sooo slow
Mine takes a really long time too, though I haven't measured it yet. I just plug it in at night when I go to sleep and it's done in the morning. The battery lasts me all day.
Is there a reason you need to charge it while you're awake? This thing lasts 5-8 hours easily; surely you aren't on it that much!

From experiment, it looks like taking one hour to charge 10%. So total time for full charge is about 10 hours. I used the nexus 7 charger and it took about 16 hours!
No problems charging here, I just charge overnight

Mine also charges very slowly. Discharges when on charge if you're using it (depending on what you're doing of course).
Hello Experts,
I received a new nexus 4 and noticed that it takes around 3.5 to 4 hrs for complete charging from 5% to 100%.... is it normal? my other sony xperia seems to be charge in about 1..5 hr
since i am new to Nexus 4, not sure what is the avg charge time and should i call for RMA? Please let me know what is the avg time for charging.
thx
Ganu
Perfectly normal. You want a nice slow steady charge, especially in a sealed phone. The battery needs to last as long as possible. Fast charging batteries significantly reduces their lifespan. My old Nexus S takes the same amount of time to charge from 5%.. 3-4hrs or so give or take.. I still have the two year old original battery and it holds a charge just as well as it did the day I bought it. Meanwhile my 15 minute charge AA batteries I bought last year lose their charge in a week just sitting on the desk.
Mine is just about the same, but that's under use. If I don't touch the phone, it typically charges to 100% in about an hour.
And if it's through USB.. um.. more like 8 hours to fully charge.
Battery widget reborn (awesome app btw) says my phone usually charges in about 2.5 hours. This is on Qi though not sure about the regular wall charger.
2-2.5 hours for me on usb wall charger and Qi Orb.

From 2 hr 45 min (from around 12-15% juice left), my charge time has reached to 3 hr 30 mins now (i.e. from 1% juice left)... 14% juice wouldn't make such a huge difference so don't really know why it increased..

yes, this is one of the reasons i started this thread to understand what everyone is experiencing.... i called up the google customer support and they are ready to send in a RMA as it appears to be a higher side...
so let me know your thoughts guys...should 3.5 hrs charge time considered high and warrant a RMA? share your thoughts.
^ Hmmm.. I doubt if this would mean anything serious or worth RMA-ing. I can but I won't RMA my device because it's been exceptional so far. I am fairly happy with it and wouldn't want to get it replaced with a defected one.
Its perfectly normal especially from around 5% to 100%.. In my experience if you dont let it get below 20% it usually charges faster. I wouldnt RMA it especially if your phone is perfectly fine in other aspects.
I tried with a different charger yesterday and it took similar time. The charger has same voltage input levels.
You charge 3 hours, for only double the lifetime. How pathetic, actually. I didn't thought that the battery life would be that bad. I can hardly make trough 1 day, if I play some games, make some calls, and use a little bit of internet. On the last charge I got 4Hours of screen on time with 15% left.
Gosh, at least it's fun to use it. :/
Hi guys! Just got this baby today and battery is dying soon! Just wondering if you guys let it charge overnight for 8 hours on the first charge?
It'll take 3 or 4 charge cycles to reach full capacity. And by soon, how many hours of screen on time are you talking about?

Well I was just asking if you guys charge it straight for 8 hours on it's first charge lol :X
Electronics inside stops charging once the battery is full. You can leave it on forever it won't make a difference.
You can charge it while turned off (maybe one or 2% more will go in) but other than that don't worry about it.
But yes, first couple of cycles are aweful, use it for a week or two, then the true battery capacity will reveal itself.
Also you might wanna discharge it to auto-shutdown and charge it up to 100% uninterrupted for best results.
To answer your question quickly: no, I only charge new devices until they're full unless I leave them overnight.
If you do some math: 4325mAh battery being charged at rate 2A (that's the official charger right?) theoretically it should take 2h10m to fully charge the battery. Of course there are losses and everything but it shouldnt take more then 3 hours.

I just leave it on the charger overnight. Anywhere from 6-10 hours.
I thought the charge time would be long. This morning in class my battery dipped down to 12% as the class was wrapping up. I got back home around between (9:50 and 10am) and started charging my note 2014 while it was powered off. In ~2.5 hours I'm around 55-60%. Personally I don't think this is too bad at all.
What have your experiences been like so far?
Update. I just unplugged it and I'm at 91%. This thing charges much faster than I thought. What were the conditions in which reviewers said it was 7+ hours?
Update: I'm also interested in how long the charge tends to last for you.
mine was ~2.25 hrs from 20% to 80% then ~1.5hrs for 80%100%. the fast charge cycle is pretty decent, it's that last 20% trickle that can feel like it's dragging on. bmw pro says 4:14 for a full 0-100% charge which seems to be in line with my results.
I put mine on the charger at 5% before going to bed. When I got up 5 hours later it was fully charged. Not sure when it reached full charge but definitely less than 5 hours.
From 5% to 100% in 4hours en 45 minutes.At 5% screen on time of 7 hours en 24 minutes!

This occurs with mine as well. It's that 80-100% that takes a while but when I charge it anywhere before that it's pretty fast. Probably helps with the long term battery life. Which I'm fine with.
I'm thinking that review got a bad battery. This happened with my first GN10.1 when it took forever to charge after using it the first weekend.
I swapped it out and the new one charged fairly quickly (considering). This new tablet seems to be just a little longer to charge but not 7 hours.
This has been about my experience too. I was really worried before because a lot of reviews said this tablet takes forever to charge to full. Glad to see that smart-charging mitigates this almost completely since an 80% charge easily gets me through a full day of moderate use.
Mine has been 4.5-5 hours, which is AWESOME!
People expect it to charge as fast as their phone need to realize the battery is much larger! I have had the same experience with a new, bad battery taking longer to charge as well though.
The 1st picture attached is my charge time for one night so far. Using the System Monitor app. Really digging that app. You can even have floating windows that stay on top as you run things.

my charge times are about 4 hours from 5% to 100 with screen on and energy saver, with it off, i go from 5% to 1005 in about 3 hours
As pleasant a surprise the charge time was I must admit that the charge tends to go pretty quickly. I'll post back with specifics when I get a chance to properly mark the times and usage.
