Regarding my battery,
Whenever I use my tablet for Facebook / Twitter, My phone turns hot and the battery drains massively.
Is there any solution for this? Or is my pcb board broken.

When I swap the battery in my note 2, it won't power on until I plug it in for a minute even if the battery is charged. Any ideas?
Edit: some more info: I was having bad battery drain on CM10, installed battery doctor. I thought I'd try a new battery as well for the battery drain and started noticing that it wouldn't power on after changing the battery. I formatted, refreshed and installed slimrom 4.3. It looks like I'm getting better battery life, but I have basically nothing installed. I'm still not able to replace the battery without a power cable to "jump start" it. Its almost like the phone doesn't even detect the battery until I plug in a cable.

Update: I don't have any better battery life with slimrom. I'm loosing about 8-9% an hour in standby. About 5% an hour with the phone powered completely off. I have 3 different batteries that all hold charge when out of the phone.
Are you using one of those crappy GOLD Chinese batteries? That might be your problem, don't know why, or of all of them cause issues, but a co-worker bought one for his HTC and was having a lot of issues.
For the battery drain you should at least try to diagnose what is causing it. Either install Wake Lock Detector (free on Google Play) or Better battery Stats (paid on Google Play, free on xda).
Most of my battery drain are constant and numerous wake locks caused by Goolge apps, including Keep and Google +. Once you know what is causing it, it will be easier to fix.
Update for anyone with similar issue..
I followed a guide on here to get back to factory stock (no root, stock recovery, etc). I had problems getting into download mode at one point and thought I was completely bricked until I decide to try booting without the battery even in the phone (powered just by USB). I was able to get into download mode that way and revert to stock.
Here's the strangest part to me: battery life is now back to normal. Not just regular use and standby, but completely powered off, I now only loose 0.5-1% an hour where I was loosing ~7% when powered off.
I don't know if it makes a difference, but I've also been keeping my wifi off. I'm experiencing terribly weak wifi transmission (still trying to figure that one out) that will cause my phone to loose wifi connection, or it will stay connected but is unable to load anything. Maybe my wifi issues relate to the crazy battery problems. Who knows.
Hi I have the same issue on my Galaxy Note 3 N9005. Battery drain when phone completely off. Can't turn on after swapping battery without charge. Tried factory reset, flash stock rom issue still exists. Any suggestions? Thanks.
Welcome! I've got Galaxy Note 3 for 3 days and i'm not satisfied about battery life. I read that it is possible to work on one charging even 3 days! I can work on my max 8h!!! I've got wifi/bt off, battery saver mode on, screen bright on auto and -5, only gsm (not LTE), no sync, no facebook app. When i'm working on my phone i can easily see how battery is discharging When the battery is full and after 10 usage i've got 90% without doing nothing special. Is my battery broken? shoud i use warranty?
You got some app going crazy or something. I get apps that hang sometimes and will kill my battery in a day. Lately ive been paying attention and trying to kill apps that are uselessly draining and ive only used a third of my battery in 24 hours. Just gotta hunt the problem down.
Regardless, its probably just software and not the phone itself.
My Galaxy Tab S SM-T705 was working fantastic, untill one day, the battery dropped to zero. Then it got stuck. Wouldn't charge. Wouldn't turn on. I tried multiple things charging overnight with the original charger. Then I tried charging overnight with a heavier charger (note 4 power charger). That was until I read a guide on tech republic about how I needed to do a battery pull to negate minor trickle charge from the battery. Anyhow, I ripped the back cover off and took it off, and voila it started working.
However, I began experiencing crazy battery drain. I suspected that something was wrong with the battery; that I had damaged it with the overnight charging and stuff.
To remedy this, I ordered two spare batteries off of AliExpress. Hoping that I'd get this fixed by replacing the battery. This was until something happened that made me suspect that the problem is not with the battery
Today; I powered it off to replace the sim. And let it turned off for 6 hours or so. And while completely turned off, it drained 50-60% battery. This means that there are two possibilities.
Either the battery is ****ed and is draining battery ( i can test this by charging it up fully and then disconnecting it from the motherboard and then connecting it again after a day - if its drained while not being connected to the motherboard, then its the battery that's at fault)
If however, the battery only displays drain while being connected to the Tablet/Motherboard, then there's something wrong with the tablet (and its likely in this case that I can't do anything to fix this.
In scenario two, though, I was wondering, is it possible that it has something to do with the connectors on the back cover? There are these antenna that you can see in this picture: http://dl-1.va.us.xda-developers.co....jpg?key=YuQ4sx_xJyTckKe2XxlcWQ&ts=1436984729
I suspect that the power drain may have something to do with the antenna's on the back cover. Anyone know what those antennas are for? They say stuff like LTE and WiFi however, I've taken off the back cover and its still connecting to mobile data and wifi etc. So these may be extra antenna's etc.
network, wifi and bluetooth and gps need access to an antenna, have you tried turning on airplane mode to see how much power your tablet uses then.
Install GSam Battery Monitor, It calculate your battery drain in mah, also it will show if your tablet is going into deep sleep, and it can list the apps that use the most power in the App sucker.

The app below will allow you to see how many percentage points your tablet uses, for example overnight.

The circled chip keeps on heating, even when I turn it off. I suspect this might have something to do with my battery draining... can anyone help?
I disconnected the battery from the motherboard, and it didnt draining. But draining when connected.

Im Having exactly the same problem, and I say its not software, its the hardware! suspect in the power IC that manages the energy for tablet is problematic, check if your tablet while idle/turned off is heating on the bottom back. This excessive heating is the response of a malfunctional component.
I think the only way to solve this is sending to samsung specialized support to change the defective IC.
POst if your problem solves, I didn't solved mine yet.
I have never had good battery life on my Galaxy Tab S 8.4 ever since I got it in April of 2015. I did a battery test using the Geekbench app and it gets only 4-5 hours of life. And since this is just screen on time, my battery normally drains much faster. I've tried 4.4 Kitkat, 5.1.1 Lolipop, and even 6.0 Marshmellow with no real difference to battery life. I have also tried battery monitoring and battery doctor apps, as well as deleting the batterystats.bin file and even ripping my tablet apart and reseating the battery connector. I've thought about replacing the battery, but the only battery i can find is from NewPower99 and that's $60.00, way too much for a battery in my eyes.
Plenty of battery`s on eBay.

me too in my tab s sm t700
battery life is die quickly in stock rom 5.0.2
Keep your screen brightness as low as usable, avoid white or light screens as they use the most power it is a disadvantage of oled displays, I keep my display on auto -5

Downgrade to KitKat, as the other day i upgraded to lollipop and the battery was dropping 1% every other min its a joke. So i downgraded to KitKat and it gives me easy 3 days use and that's heavy use T705!
How to downgrade t705 to kitkat
I use a built-in feature to keep the screen toned down. In the display settings, there is a reading more feature where I select the apps I primarily use, including my default launcher Nova Launcher, and it tones the screen brightness down while those apps are in focus. Like right now while I'm using the Tapatalk app.

Head over to http://www.sammobile.com/firmwares/ download your firmware and flash using odin it's real simple!
Found this over at Android Central as last few days my battery has been all over the place, as it was fine before. Anyway my battery dropped to 5% turned it off. Waited a minute or so, turned it back on bat was showing 45% wow so i'm draining it again Ive let it drop to 5% again this is the 3rd run now its showing 42% crazy credit goes to rouge-hawkins
I had the same issue on my brand new Galaxy Tab S LTE version with Exynos chip. I was like WTF on the battery because the moment i disconnect it from the charger it would soon drop to about 85% in 5 minutes. Then the dropping continuous in huge leaps like from 70% down to 30% while i'm just browsing the web. Then when it came down to 5% it would turn off. The moment i plug in the charger while the device is off the battery level would start at 40%. It was erratic for 2 weeks. Good news is i was able to resolve this without doing factory resets.
What i did was the moment the battery came down to like 5% i completely turn off the tab and turn it on , the tab reported a higher battery level like 45% then i continued using and until it drops again to a lower level like 3%. I power cycled the tab again and it reported battery level at around 24%. I used it again until battery level went to 3% and rebooted it, then it reported 12%.. used it again until the device really wont boot anymore. Then i used a slow charger. I used the 1A usb charger from my other phone (while off) and waited until 100% full. Then things became normal.. it reports battery level fine after. I also installed Clean Master and disabled some background apps and Samsung bloatware that i really dont use. Everything is ok now and im happy with my Tab S 8.4... hope this helps for those who got their device over the holidays. I resumed using the 2.1A default charger and issue doesnt seem to repeat anymore.
Hi,
I'll have rooted Galaxy tab 3 8.0 and since it's old it has been mostly only on light use with org rom for couple of years now. Org battery was going down, sudden shutdowns on heavy use and didn't have a juice anymore so I decided to order new battery. While I was waithing new battery to arrive I didn't use that tab and I forgot it to a freezing work car with power on so that tab/old battery froze and tab shutdown. Problem is that it won't charge or start anymore with new or with old battery. Not with any button combination or not with any cord or charger or pc, not with cold battery or not with warm battery. I also used multimeter to check that there is enough voltage in new batt to start. It just doesn't do anything. No light, no charging icon on screen, nothing. So is that galaxy tab just froze to death(was max - 10'c) or is there any other ways to try to recalibrate/reset power circuit on tab so it starts to understand again when there's battery or charging cable on? Now it's just stupid thing that doesn't seem to understant that there's battery inside and power cord plugged in.
What if it's not only the battery that got damaged? I bet there's more, that's why new battery does not help.
