Your Cable (USB) is likely the culprit.
It's not giving out proper juice to the tablet (1800 mah) and hence taking so long.
Mine had similar issues and switching to another cable (thick wire and shorter in length, i think it's a nokia cable) and it gives 1800mah current constantly and charging times are around 2.5 - 3.5 hours depending on how depleted it is.
There is an app called galaxy charging current, that can tell you how much current you are getting from the charger.
Update:
If you feel battery constantly being drained
1: It could be Google Now location services.
2. Bad Corrupt media files (Bad Music: Id3 tags usually or at times bad frames) can cause media server to crash and keep trying causing drains. There are few tools that can check for bad audio files and fix the headers.

[Help Request] Charging issue

I been having troubles charging my S4 and I used the one that comes with the phone when you buy it and it charges completely but now I have a different one that's made by Samsung but my phone wont charge completely. I put it on the charger at 10 am and by the time I go to school its at 60 or 70 percent everyday,even when it's on airplane mode. Is there a way I can fix that? I tried wiping my battery stats and I also got Battery Doctor but that doesn't help either... So can someone help me with this issue?
Additional information:
Running Wicked Rom.
Stock Battery
Not even 2 week old yet.
I haven't dropped it at all.
No water damage at all.
Also charger is a 1.0 amp charger made by Samsung.
I'd consider flashing to stock and starting over, buying another battery, or another charging cable.

I still use the stock charger and cable that came with the phone and my phone charges at approximately 1% per minute (or even a little higher) when it is on the charger. If yours doesn't charge that fast try another cable (borrow one if you have to or go to the T-Mobile store and ask them to use one of their cables to test it for you). Good news is that even if your battery has gone bad you have a phone for which the battery is easily replaceable.

I have figured it out. I uninstalled a few programs that wouldn't let my battery charge completely. I noticed there were three applications running while my phone was on and those thee programs were running all the time without me knowing. So I Delete Battery Doctor, Clean Master, and Wakelock Detractor. After I uninstalled those, my phone was charging a lot fast and when I woke up today, my phone was at 100% and I was happy. I thought I would have to re-flash my rom.

[Q] M8+Nexus 7 charger ??

Hey guys,
I was wondering if anyone tried this on the M8.
I used a nexus 7 charger for the M8, I didn't check if the charge time was faster because I plug it before I sleep but the weird thing is that the
battery life is somehow significantly better and lasts longer.
On my old ONE X, if I used the nexus charger, it would charge the battery faster but it will also drain quickly. I read also that using a tablet
charge (2A) will damage a phone battery on the long run.
I dont know if this has to do with the snapdragon 801 or the quick charge technology? or am I just imagining
what are your thoughts?

Funny you mention this. Wether or not its relevant (Not trying to debate the fact), I like to "condition" my phone batteries when I first get them, full discharge - recharge while turned off for first 3-4 charges or so. But I did in fact use my Google Nexus 7 charger to do so, and on the 4th charge I got 6 days 8 hours before charging on light usage. Minimum 1 hour talk time per day via 2 30+ min calls, and 20+ texts a day. (Light facebook / game usage for the sake of seeing how long it will last) Not sure if it has anything to do with the way I charged, or the charger, but I'm pretty happy with it. Just on reg power saver, as you can see the Sprint version did not have Extreme power saver update yet.

WOW, 6 DAYS now thats great!!!
I think it because of the nexus 7 charger
Ok, some facts:
Qualcomm quick charge 2 will allow very quick charging (around 1 hour), but there are no chargers yet.
Conditioning your battery hasn't been required since we moved to Lithium ion, 15 years ago.
Using a charger capable of delivering more current won't make the battery draw more current, in fact, with HTC, it might draw less (the device checks the data pins are shorted to detect a mains charger). Thusly, it won't affect the longevity of your battery.
Using the nexus charger is highly unlikely to have increased the charge in your battery, or reduced the power consumption of your device. If it lasted longer, you used it less.

anyways thanks guys for ur feedback

[Q] Battery problems: not charging when in use

My 12.2 Tab Pro loses about 10% charge for every hour in use: about right, I think. It takes about an hour to charge about 10% when not in use: rather slow in my opinion.
When I am using my Tab while connected to the mains, it will not charge. In fact, it loses about the same amount as when it is not being charged.
Using in this context is reading books (Kindle), reading newspapers (PresReader) and web browsing.
I have tried USB 3 and USB 2 plugged into a mains plug, and USB 2 directly connected to a mains plug. I have tried different cables and plugs. They all behave similarly.
Should it not charge when in use?
Are you using the Samsung charger and cable that came with your tablet?

Amongst others, yes.
I have same problem with mine. Battery can die super quick from 100%, then a restart shows it with 60% (as example) battery. Are you rooted? I've seen others with similar problems, but no answers. Thinking of sending back to get fixed

Are you charging it from the computer?
Mine doesn't take an hour to charge 10%. You probably have a defective unit.
If it takes an hour to charge 10% using the stock cable and charger, there's a hardware fault somewhere, be it your cable, charger or the tablet itself.

USB ports do not provide enough current to charge these devices. I understand that, when on, the power drain exceeds input from USB sources. I use AC with adapters rated at 2 A. I also have a car charger with that current rating that plugs into the car lighter. USB ports, whether in computers, cars, or airport lobbies are useless.
If you are using wall plug rated at 2A and are not charging, then one of the 3 components is bad (charger, cable, or phone).

I'm also having the same issue . I have left it plugged in ( wall outlet ) and off for an entire day and it still wasn't charged 100% . I am rooted .

I bought my Tab pro 8.4 in June 2014. I use it about an hour each day and charge it when the charge drops below 30 percent.
Recently I have noticed, it takes all night to charge. This should not happen. my Ipod touch charges in less than 1 hour and its an old version 3, (6 years old or more)..
I am using the wall plug that came with the unit, to charge it. It should not be taking 12 hours.
This seems to be a problem with these 8.4's.
there are a number of possible causes: bad battery, port, charger, power source, too many apps .... you might want to read this guide on how to fix an Android phone that doesn’t charge (or discharges) when connected to a power source to help you identify the cause and fix it

I have the exact same issue with My Galaxy Note Pro. It will not charge while in use and the battery drains extremely fast even with most all settings turned off and screen brightness turned down. I turn the tablet off every night to charge and the charging speed is extremely slow. I am using all Samsung OEM cables and chargers. Ive tried USB 2 & 3 cables with no noticeable difference. I am going to do a factory wipe and then closely monitor the power useage. Im starting to think that there is an issue with the Note Pro based on the sheer amount of users reporting the same or similar problems.
If anyone has figured out the culprit behind this issue, please pass it along!
Battery indication issues
I have the same problem with charging the Note Pro 8.4.
After some investigation and multiple tries it seems very much that the reported battery level is not in line with "reality".
It happened numerous times that while the tablet was on and charging, the battery level did not go up or only 1% every hour or so. After reboot the reported battery level was much higher.
I decided to throw some apps from the tablet which vastly improved the battery level indication and more or less seem to work as expected. I know from previous experiences with my Note 2 that some apps/widgets can wreak havoc on very basic functionality like charging. For example the stock picture frame widget on the old Note 2 had the effect the charging icon did not update. After reboot of the phone it was much better. Removing the widget solved the problem.
All in all carefully check installed apps/widgets on the Note Pro (8.4) because the firmware does not seem to cope well with certain apps/widget combination whatever that may be...

[Q] Tab Pro 8.4 (stock, unrooted) not charging properly. Worked fine for months.

Did anybody get issues months after they'd purchased the device?
My 8.4 Pro worked perfectly (6-8h SoT, 100% charge everytime) for about 2 months, but hasn't been charging properly since yesterday. I tried combos of all my charger/cables - they are all giving 1A+ rate on my other devices, but not even being measured on the tab (vis Ampere). Battery has been stuck around 50% for ages. I'm in India, so no easy way to get this back to the US for warranty replacement. Besides, by the time I return to NJ, the tab will be out of warranty.
Please note that I have also factory reset it. The problem, unfortunately, persists.
What should I do? This may not be a software issue: I use this tab while I'm on a stationary cycle, so maybe that motion somehow 'knocked' the battery out of whack somehow? Should I open up the tab and do a battery reset? Is there any, less dangerous, solution?

You need to use a 2A rated charger and really there is only a few that qualify, I suggest you only use the Samsung charger as they seem to have a certain way to charge it, chargers do go bad sometimes so look for an official replacement (they cost like $5 on ebay), beware of knockoffs though since they look identical, I suggest searching for the same model number on the charger. IE : EP-TA10JWE
anyways here are some things to try in the meantime
1. drain the battery down to 15%
2. hold the power button down and choose the Power Off setting, wait until you feel it vibrate, now let the tablet sit for an hour in this state. (do not hook it to a charger)
3. after an hour or two, plug the charging cable into the table and let it charge (do not turn it on), you should see an animated battery screen show up a few times, see if it reaches 100% in this "powered off" state.
if it does then that could mean there is an app running in the BG when it is started causing a lot of cpu load or keeping it awake..
I've so far had my tab 8.4 for almost a year and the battery is still holding up with 8-10h of runtime (depending on what I do). and it always charges to 100% using the samsung charger.

The chargers I tested were rated 2A, and their cables were 28/24 AWG. On my Dell Tablet, the same setup was giving me around 1300 mah. On the pro, most of the time the current didn't even get measured.
Tried the other things you mentioned. It charges, overnight, to 100%, but despite the factory reset, weird battery behaviour is observed: slow recharge, jumping from 93% to 100% the moment i connected it to the lappy to transfer data, etc.

You are using the Samsung charger?, I noticed with other chargers for some reason when the battery gets near full the mA drops to under 200mA and stops charging the battery or its just enough to keep the tablet running, this does not happen with the Samsung charger it mostly charges the tablet at 1880~mA, when its in the 90% range drops to about 600-800mA so it can still trickle charge the batt and provide enough power to keep it running.
I have tried other chargers like the 2A HP Touchpad Charger (was supposed to be the best charger out) and some 2A powerbanks - and they all fall short near 90%, just don't pull enough amps, I think the samsung charger has a higher voltage too 5.60v where the others are around 5.30v
btw I have an actual hardware mA cable that shows the current in realtime, I'm not sure how accurate the battery monitor programs are for android without root access, since without root I don't know how they read the system files.

Getting a slow current with the 5.3v samsung charger and cable as well. But yeah, using software (GSM battery, Ampere) to get the charge.

Hm I suppose the battery could of went bad if it wasn't being charged properly by some chargers for example if it was never reaching 100% then the system never shuts off the charging mechanism and will essentially cook the battery causing it to die faster then normal .
If you had root access you could check the status of the battery and it would report the battery info in stages - very good (brand new), good, bad, fail ..etc I am not sure if non root programs can access this info.
I guess there are a few extra things to try.
1. A new Samsung charger, it might be possible yours went bad.
2. re-seat the battery, though this requires opening the tablet possibly voiding the warranty or causing other damage - maybe take it to a repair shop if you have difficulties, from what I have read on this forum it has solved numerous cases like yours, not sure exactly what it does perhaps removing voltage from the hardware causes and glitches to reset like from accidental static electricity shocks or if it just re-calibrates the battery like it was replaced..etc, it might just be the connector comes loose, anyways it sucks Samsung didn't included a reset button since it's a needed feature for sealed tablets)

This is a fairly common issue on this device. Its a defect, I'm thinking its the "smart battery" circuitry on the battery itself (my understanding, at least some of the metering is done on the battery by this circuitry). Its been discussed at length on the following thread; with the suggested fix being to open up the tablet and "reseat" the battery: http://forum.xda-developers.com/galaxy-tab-pro-12-10-8/general/reseating-battery-wonder-battery-life-t2944610
I've had this problem for a while now. The issue was non-existent or rare at first, then got more common after owning the device for a few months. Haven't used any apps to measure the mA, but this is across 3 or 4 different chargers, 2 of which are original Samsung 2A chargers (had another one left from my broken Note 8). The issue also persists whether on stock ROM, custom TouchWiz ROM, or custom AOSP ROMs.
Sometimes the tablet will charge fully, no issue. Sometimes it will stop somewhere along the way (well short of 100%) and doing a reboot will usually get the charging "going" again. Sometimes I will need to reboot 3 or 4 times to get it charged to 100%. I've also tried factory resets, but its hard to say whether this helps or not.
Short of rebooting while charging, there isn't much I've found to help. I haven't tried opening the device to reseat the battery.
Maybe the usb port in the tablet has some debri in it. Try blowing it out with some cpompressed air. The symtoms sound like a faulty usb cable but if you have tried different ones it might be the port.
