It's been a staple of their latest tablets unfortunately. Just make sure you're using the stock cable/adapter as some of the aftermarkets don't have enough power. For example, I have a 10 foot cable but it only puts out one third the power then the included power cable using the same adapter.

Try using Galaxy Charging Current lite it helped me. I was using a Anker intelligent charger and it took forever to charge it. App showed current at 350-450mA. Used Samsungs and it showed 1800mA.

I have to agree, just received the tablet today albeit stressed out to the max because the fedex guy marked it as delivered when it wasn't to squeeze out extra minutes for a break (seriously?!?) I thought it got ripped off! So, back to the battery, I turned on the tab, beautiful this thing is by the way...and was at 62% out of the box. I began charging it using the included power cable and adapter, and 3 hours later I realized just how long this was taking to charge. Granted I was using it practically the whole time, I am hoping a higher amp charger will fix this for me.

[Galaxy Tab S Q&A, Help & Troubleshooting] BarryH_GEG:
Charge time isn’t particularly fast on any of the devices, but the 10.5-inch model in particular takes a while to make it to a full charge. The 10.5 will reach a 90% charge in just under 4 hours, but to make it to 97% takes another hour and the last 3% takes another 42 minutes on top of that. Usable charge time is competitive, but if you’re obsessive about always charging to 100% the 10.5-inch model does take a while to get there.​

Slow charging NO charging

I hope this is okay to post here since it is a charging problem. I am on my third SM t-800. Mine stop charging all together! First one charged one time then stopped. Second on would not charge at all, It used up its factory 45% that it shipped with and nothing more. Third one was best by far and charged untill this moring and has stopped. Now, here are the details. I checked the cord by pluging into my note 3 on all of them. Infact my wifes Note 2. They charge fine. I don't have my ameter to check ampers but they clearly are delivering volts to the other devices. Now get this. I have a Bose external speaker that uses a mini usb. I plugged that one into the tablet and it is charging right now. Of note I had a concern that maybe some how the socket was bumped on the tab and somehow messed it up. But that is a long shot since the first two were used while only on a desk. So this third one has been supper "babied". I'm so frustrated right now.

BTW my first tab charged very slowly. 6-7 hours or so. Maybe more? I feel at this point the pins in the tab are not making contact. Any thoughts?

Just got of the horn w/ Samsung. Got issue taken care of. In short, the phone tech mentioned ampreage and I yanked the AC transformer off the wall and checked it. The factory transformer is 5.3v. 2.00ampers. In the dark last night i plugged into a "white" charger. An ipad charger I think, that is 5.2v. 2.4amp transformer. I switched the cord to the corect transformer and the tab is charging. Apparenty the chip in the tab was protecting the unit from over ampreage and it shut down charging. I know better than this and feel like a fool but thought I should let you all know what happened. This brings up a issue. Slow charging.... could the slowness be caused by a transformer with say 1.5 amps? Maybe the tab will let it charge but at a slow rate? Just a thought. Moral of the story for me? Plug in the tab in a lighted area, and into the correct charger.

Charging is a little slow, but the battery is large, so i accept that, but when it's charged 100% it lasts for ages. Faster charging shortens the life of the battery anyway. I could easily get 7- 8 hours constant surfing out of this tab. I've been on it now for over 2hrs surfing and it's used 13% . I always use auto brightness.;)

[Galaxy Tab S Q&A, Help & Troubleshooting] ramiss:
Technically this is not true at all. It is heat that hurts batteries. You can charge as fast as you want as long as you keep it cold. That being said, Lithium Ion batteries will take a much faster charge rate and not cause heat. You could easily charge this battery in 2 hours, but the common chargers aren't that powerful.
[Galaxy Tab S Q&A, Help & Troubleshooting] ashyx:
There's a reason why manufacturers limit charging current. Whether it be heat related or otherwise. Otherwise there'd be 5 amp 1 hour chargers supplied. There is no extra cost to the manufacturer involved to supply a higher current charger, so there is obviously a reason.
[Galaxy Tab S Q&A, Help & Troubleshooting] ramiss:
I fly electric RC planes and charge Li Ion batteries at 5 amps and higher all day long. Similarly these planes draw 40+ amps when the engine is running.

If Tesla can charge its newest car in 30 mins then surely my little tablet doesn't need to take 8 times that long!

The reason they don't make this better is that 1 amp chargers are common and easy for Samsung and everyone else to buy in bulk.

[Galaxy Tab S Q&A, Help & Troubleshooting] john81uk:
As dingchow said. Try the app as its good to test of the charger is working correctly. I have found many faulty chargers just giving 300-400miliamps charging when a fully working Samsung charger levels off at 1200. This makes a huge difference to charge times.
[Galaxy Tab S Q&A, Help & Troubleshooting] Laurence1956:
I had the same problem, here's how I solved it:

1. Installed CM Battery ans set it to fast

2. Set my galaxy to power saving mode (grey screens)

3. Closed all applications

4. Left the tablet overnight connected to the charger

[Galaxy Tab S Q&A, Help & Troubleshooting] UpInTheAir:
My Note Edge (near identical hardware and kernel source to Note 4) has same "Fast Charge" feature. MAX stock is 3150 mAh with HV Mains charging ("High Voltage").

The Samsung Galaxy Tab S has Mains AC charging feature. MAX stock input & charge rates during screen OFF are 1800 mAh. MAX stock input & charge rates during screen ON are 1200 / 1000 mAh respectively.

From my SkyHigh kernel Synapse description:

This is the limit with stock kernel, so anything more than this is purely placebo. Many monitoring type apps may give incorrect reading, you need to take them directly from sysfs for average and "live" values (dependent on polling time).

Hope this clears this up :)

I have just about 6 hours of battery (mostly web browsing, plus a bit of simcity), and my tab fully charges after 5 hours or so.

I use a rooted and debloated TW 5.0.2 rom, with nova launcher. I am also using basic screen mode, I wonder which one is the most battery effecient (this one, or the adaptative one).

[Galaxy Tab S Q&A, Help & Troubleshooting] _RoRo_:
A couple week ago, I had to reinstall the default ROM, then I rooted the device, installed recoverry and debloated it again.

Do you know how to fix this?
[Galaxy Tab S Q&A, Help & Troubleshooting] rookie12:
Something may be wrong try installing skyhigh kernel and set the charging rate maybe that will help mine takes 2hours 0 to 100%
[Galaxy Tab S Q&A, Help & Troubleshooting] _RoRo_:
Thank you for your reply

I have to say I am a bit reluctant to try such a risky option.

Would you think a battery calibration would help?

Would you also think flashing the default kernel (if available) would help?

Unfortunately, i don't have any other compatible charger to test with. My huawei charger doesn't fit samsung's port :/
[Galaxy Tab S Q&A, Help & Troubleshooting] UpInTheAir:
Although there is "risk" in anything you might do, most issues are due to users incompetence (failure to research, read, follow instructions etc), not the act of flashing ............

No, default kernel should do nothing.

Edit: Those "battery calibration" apps are usually do nothing, as some devices might require a fuel gauge reset (battery scaling). Each device sysf location may be different, so writing to this will vary between devices. Using my kernel and Synapse will expose this with easy in app instructions to calibrate.
[Galaxy Tab S Q&A, Help & Troubleshooting] _RoRo_:
alright, i'll probably give it a try then, thanks!
[Galaxy Tab S Q&A, Help & Troubleshooting] _RoRo_:
I wanted to give you an update: before installiing the new kernel, i wanted to try a couple things.

So I tried first to wipe dalvik and cache, then my charging time jumped to 10hrs!!!

Next, i tried to calibrate the battery using the app called battery calibration, by NéMa. Now charging time is exactly 6 hours. so it seems to be the fix in my case.

Mine charges 1100mah till 1400mah but my deafault is 3000mah skyhighs kernel before i got 2000mah so i donr know what happend
[Galaxy Tab S Q&A, Help & Troubleshooting] Tinderbox (UK):
So your charging at 390ma you have to keep pressing the refresh button on the free version and let the average build up for a while, but if you are charging at 390ma something is wrong, make sure you are using the original cable and charger, if you are, then the cable or the charger is most likely faulty.

The max is the built in maximum limit of 1800mah the battery will not charge faster than that no matter what charger you use, my T800 charges at around 1550mah.

[Galaxy Tab S Q&A, Help & Troubleshooting] madhu2250:
hi friends,who ever is facing the slow charging issues with tab s 10.5,here the solution which i found,the problem is with the cable,change the cable and problem is solved,if you want your tab to charge fast get oneplus one data cable,which i am using now to charge my tab,with samsung original cable and adopter my tab charges for 6 hours to get 100%,with oneplus one cable it takes 4 hours
[Galaxy Tab S Q&A, Help & Troubleshooting] _RoRo_:
madhu2250 is right, my tab was charging very slowly with the original cable (8 to 10hrs, at around 400mA). I tried an other cable (namely a huawei one) with the original charger, and now the tab charges in 4hrs at 1400mA.

On the other hand it looks like my battey life decreased just a bit (from 5hrs30 to 4hrs30-5hrs), but i have to check that. I read somewhere that faster charge also means lower quality charge
[Galaxy Tab S Q&A, Help & Troubleshooting] aboalghool:
The slow charging can be explained by the 7900 mAh battery found in this device .. 3200 mAh found on the note 3 which eventually means it would take like 2.x times the time to charge it .. samsung should have considered making these power hungry devices have fast charging method .. i think it the best way to solve the issue
[Galaxy Tab S Q&A, Help & Troubleshooting] jolly28:
There`s a connector under the case that can come partially loose when subjected to traumama...it connects the mini plug to the phone . It is very easy to remove the case and simply press down on the connector to ensure it is making full contact and that's it.

my phone fell right onot the pin while charging, while it charged slowly there was a red x icon on the battery. I had opened the back previously so I simply checked and that was all that it took.

Get the Galaxy Charging Current App

I've got a Galaxy S6 phone charging perfectly on the original S6 2A charger and cable.

My Galaxy Tab S was extremely slow on the same charger and cable.

But I assumed the because the S6 phone was charging ok that the problem with the Tas S slow charging must be with the battery or the Tab itself.

I installed the Galaxy Charging Current App and was amazed to see the difference changing the cable made.

Using the original S6 2A charger and cable it charged at 300mA

Using the original S6 2A charger and spurious cable it charged at 1400mA

Thank you to one of the earlier posters for suggesting the Galaxy Charging Current App.

[Galaxy Tab S Q&A, Help & Troubleshooting] Tinderbox (UK):
The 10.5" takes 5+ hours to fully charge, this is NORMAL, the charger is only 2000ma and the battery is 7900mah, But the charger only charges at 1600ma (if you are lucky) and 10% of that is lost as heat, so only 1440ma is really being used at best, But the Tab S only charges at full speed up to 80% from then the charge rate gets lower and lower as it approaches 100%

You can use the battery charge time calculator in the link below, look at the 10% efficiency result not the default 20%

If I turn the tab s off it charges normally. I have tried different leads and same result. In settings I cannot see any reason the battery being gobbled up.

Hi,

I have a sm-t900 model, still with kitkat, and just rooted+su+busybox. I have noticed charging problems more than 1 year ago, and here are the tricks I use successfully since this time :

1/ sometimes reboot to recovery and clean cache.

2/ Place the device on a flat surface with the glass on top, connect the charging cable and slide a wedge under the connector so that the weight of the device presses on the connector without exaggerating.

The wedge must be moved away from the edge of the device at the joint between the cable and the connector, to leverage the connector, but still under connector in order to avoid damages on the cable.

I use a wedge which is about 3cm high.

I have noticed that this flat connector from samsung is not optimal for charging.

Hope it helps.

Slow charging

my galaxy tab s is also showing sign of slow charging. I got a USB charging monitor which can monitor how much voltage and ampere it draws from the charger and I have notice that my galaxy tab s when connected to its original charger (wall outlet) only draw 5v and 0.6~0.7a which is extremely low. Then I plug it into my galaxy note 4 and I getting 9v and 1.6a with screen off. So charger is not the problem. At first I thought is because maybe fast charge is off but I found out that galaxy tab s has no option to turn fast charge on off.

My guessing :

1) some how fast charge is turned off but no ways to turn it back

2) marshmallow update somehow reset the fast charge so now it become off ?

3) maybe the tablet has memory effect because i did use my note 4 charger to charge my tab s before which is rated as 5v. restarting the tab or shut down will not increase the charging voltage either.

So guys anyway to enable the fast charge back ? should have stick with tab's own charger because i think my third guessing is correct.
