Happened to my 8.4 Tab S once. Haven't figured out yet what caused it. It was basically after an OTA. I rebooted the tab and haven't seen it since.

I rebooted alot of times m itz the same... i guess i have to reflash it again.

I had this problem when i first got my Tab S. After turning off the Automatic security policy updates i had much better battery life. Its under Settings > Device > Security >Security Policy > Automatic Updates.

Ok guys.... read this....
100% -70% in 40mins. (Listening to Music and surfing web)
70% - 50% in 20mins. (For no reason)
50% - 5% in 25mins. (Played game and installing apps)
Off it, plugged charger to it. Was surprised that it shows 48% instead. Let it charge for 2 hours. Was 87%.
On it up. Accidentally pressed the Launcher option instead of Touchwiz Home. Restarted it.
Battery shows 68%, and drop to 47% in just 3mins...
This is what I'm encountering most of the time... any ideas as to why it is like this?

Got this same problem before wherein my battery acts nuts. it would suddenly jump off from a certain percentage just like yours, sometimes, it Would show 1% and will shut itself off. Then when you turn it on, it will have at least 30-40% left. Quite annoying. Tried all battery wipe tips here. To no avail, until someone advised that he pried the back cover off only to find out a loose battery terminal . I did the same (carefully) removed the connector and reinserted it firmly. Discharged the whole battery using the tablet to around 5%. Turned it off and charge it to 100 without touching. Now it last for 2 full days (2days 10hrs) under normal usage and i'm using it as my primary phone. Listening to mp3s via bluetooth willshave off 5% in 2 hrs (with at least 20 sms sent). Playing movies in full brightness will shave off 10% (standard 2hr movie)
Before: notice the sharp, perpendicular drop - and the pulsating voltage on the last part of the graph
After: more than 5 hours, no percentage drop
Normal use, yeah, i dont use it with screen on most of the time, i simply listen to music via BT. and always on wifi
Else. If it's under waranty. Try to bring it to your service center and have your battery connector reseated for you

I DIY'd mine so it's possible. You need a prying tool (the one that looks like a guitar pick) simply start from the buttom (where the UsB port is) and make your way around the tablet. please be advised that some of the clamps run towards the center of the tablet so you may need to stick in your prying tool deeper. Just be careful and take your time, and try not to break any of those locks/clamps.

But will it affect the usb port in any way? and will the cover stick back as before...?? Will there be any warranty stickers inside that will be affected prior to this DIY??

No warranty sticker found on mine. Prepare a double adhesive tape since some of the back cover part (near the IR blaster) is held by a non-fixed adhesive. Just be sure to angle your pryer towards the back cover and be careful not to wreck any of those clamps

Heh... i ald broke one clamps. Lol!!! Anyway i realised something. The battery connector (in the pic i posted here now), the metal connector which is out of the box, is connected to the mobo. But i had to press it down. If i don't the tab doesn't starts at all. Is there supposed to be anyting there to hold it tight between the back cover and the part there?

This is the connector from battery. Sorry my drawing is not perfect

Yes. You could carefully lift that up. And reinstall it - it would reset your clock though.

check out for blockage or any thing that hinders the wires to sit properly with the board. when i lifted mind before, there's a small chunk of plastic material the broke off the connector and went straight to the board where the connector is suppose to sit, i removed it then i sprayed contact cleaners on the wire-terminals before re-seating it on the board would you be able to take a photo of your board/contacts?

i am on my way home. will be back in 2 hours time. what i can tell u is that i had to put something on top of the box connector so that when i put back my back cover, it makes contact to the board. if i dun, my tab will never turn on....

1st pic: As u can see, i accidentally broke one side of the holder.... lol!!!!
2nd pic: Even thou it looks like itz touching, actually itz not. No matter how i try to it just wouldnt touch.
3rd pic: i have to fold a small piece of paper to make it as a tightener between the cover and the connector to make it connect to the board. The one that does not connect properly is the left side.
If problem still persist i guess i really got a defective battery. Will get a replacement when spare parts are available on market. I don't wanna spend fortunes on samsung repair center.

oh my, you pry the board off, that needs to be re soldered.
disconnected terminal

This is the whole thing when i opened up my cover. That iz y i say the whole thing is out.... it is already like that.

same problem ?
I think I have the same problem.. I'm just scared if it is because I rooted my device...
I have bought a otg cable to connect my ps3 controller to my tab s . That's drained my battery in a record time but I wasnt thinking it was problem.
I played with my ps3 controller and tablet until it shutdown iteselft. I plugged my tab on the wall right after and it shown 45% ... I restarted and sames battery life was showing. The app I used is sixaxis enabler.
I let it charge up to 90 % and watched movie. The battery drained quickly too..
Will do somes tests to be sure if it is normal or not...
Ah before to forgot I watched movies before and the battery seems to have decreased quicker.

[Q] Is it the Battery or is it something else?

Hi there.
My Mother has a One V which she is really happy about. But recently she says that it has been draining the battery so fast. At first i didnt really believe it (you know old people and tech), and asked if she had charged it correctly. She then told me that the charging process was also quite strange.. She had plugged it in one night, and the phone displayed that it was charging.. Then 8 hours after, in the morning it had only charged 2% ! This doesnt happen all the time, but only some times.
Now she has given it to me and hope that i can fix it. At first im just going to factory reset it, even though i dont think that is the problem. But i have noticed that what she is telling me is true to some extend. I have had the phone sitting on the table all night. No simcard and no nothing.. It had only used about 5%, but as soon as i began using it, to take backup and prepare for the reset oh boy.. It uses 1% in merely seconds! Approx 26 seconds per 1%!
I think this is rather strange and im unsure if the battery is the problem.. Do you guys have any ideas ?

Oh and i have to say that the phone is running newest stock software. It has never been rooted or anything like that.

Well, the charger port is probably bad. My first htc one m8 and my droid incredible 2 both have weak ports on them from the factory. Send it in for warranty and say nothing < about a possible bad charging port if it still has warranty. And, if nothing Less try a brand new charger, and see if that one works and if it's loose when it's plugged in. If it Is loose with new charger it's a bad charger port.

Yeah this confuses me as well. It happens once every few months. The battery drains really fast and charging is extremely slow. The first time this happened my One V dropped from 100% to 27% in 20 minutes! And just like it randomly happens it randomly goes; battery consumption goes back to normal after a day or two.
A possible reason is the charger and USB cable that is used. My cable is worn out so that might be why charging is slow but it doesn't explain why the battery drains so fast even when the phone is disconnected from the charger. So the only reasonable explanation would be some hardware problems in the battery pack.
But this is all just me guessing... I don't know for sure.

It could be the charger port. I tried cleansing it with a toothpick (heard dust could be the problem), but the problem persists

The problem here is that it happens every second time or so the phone is charged at the moment. But i have bought a new battery and will try and change it. Ill write here how it goes and if there is a improvement, so that you know where the problem relies if you are thinking about doing the same.

Same problem here. Every few months the battery drops from > 50% to 2% or so. This happens within some minutes and my phone gets really hot.
But normaly I use it with a 2 amp charger and I think this happens more often if I use chargers with 1 amp.
Edit: This happened for me with every rom I used.

I changed the battery two days ago, and i can already feel a huge improvement.. 8 hours ago i took it out from the charger. Data and Bluetooth has been on all day. Been browsing a little, and sent som SMS and stuff like that.. 65% now.
The conclusion must be that in my case at least, it was a battery hardware fault.

I'm also thinking about replacing my battery, was replacing it easy?

Yes it was actually pretty easy. Although i have done it on my One S too, and that was even easier.
Some recommendations: Get your self a repair tool kit before you start. Everything has been so much easier for me after i got that. It is all the money worth it . This is what i got http://www.ebay.co.uk/itm/261399617620?_trksid=p2059210.m2749.l2649&ssPageName=STRK%3AMEBIDX%3AIT <- They ship worldwide.
The battery i brought : http://www.ebay.co.uk/itm/321303229844?_trksid=p2059210.m2749.l2649&ssPageName=STRK%3AMEBIDX%3AIT
First i took the plate off at the bottom of the phone (the one where there behind is sim card and sd card). Unscrewed all six screws. Once done you can take all the plastic off the large plastic part (the one below the simcard and sd card when inserted, and covering everything behind the outer cover). This part is also taped/glued, but should not be a problem to get off.
After you have taken that off, use a pry tool to pry the plate open around the camera lens and flash (beware that this plate is also taped together. Unscrew the last screw behind.
Now comes the tricky part. You need another more solid pry tool to pry the lcd/board out from the front. Use the pry tool in between the screen and the cover of the phone, and all the way around. The LCD and board needs to come out from the phones front.
After that the battery becomes visible. There is nothing special to getting the plug out for it as far as i can remember and should just be pulled towards the battery to get it out. Battery is glue to the inside of the phone, but using the solid pry tool you should be able to get it out. If you order the battery i linked to, it comes with new 3M tape.
Heres a video showing it pretty good i think:

Aah so it was the battery pack after all!! Interesting to know.
Glad it worked out for you and thanks for the battery replacement links.
My One V is retired but since the battery is cheap I will buy one and replace it just in case I ever need the phone as backup.

Battery level stuck on 50%

hi everyone,
i having an issue with my battery level and it really pisses me off.
the battery level stuck at 50% - charging or not, it means you will never know if the phone is full charge(on charging) or nearly lowbat(discharging).
Also, it says "battery usage data isnt available.
it stays 50% when in recovery mode too.
i did the ff troubleshooting:
- wipe data, cache, system, etc.
- installed AOSP and CM ROM
- tried downloading battery test and everything is normal -
NOTHING CHANGED
The the battery stays upto 10+ hours but its hard to live without the battery level
hope you guys could help me with this - THANK YOU IN ADVANCE!

Got it fix
hi guys i found a fix here..
i did everything i mentioned above but none of those work so i thought it was a hardware issue and i was right.
this is what i did..
I removed the cover of the battery or battery plate (probably I had to unscrew everything) at the middle of the unit there were 3 flex connectors, and all i did was removed those 3 and carefully cleaned it. i used dry toothbrush then put the flexes back. and turned on the unit- and it workS!!!! then put everything back -
never had issue again with the battery
I am not responsible for anything if you follow what i did. there are some videos on youtube how to remove the battery plate that holds the battery..
thanks

Are you sure about this???, i did and nothings changed..

I had the same problem and i took it to a service centre,,, they told me it was the problem of the motherboard....They changed the motherboard and now its working fine

i lived with this for a month till i found an accidental fix for this. i plugged in earphones (first time) to listen to a meditation app that i'd just downloaded, and when i unplugged the earphones and charged the phone, the charging display went back to normal.

This usually happens when there is a loose connection between the motherboard and the battery. It happens on other androids too.

Same here...
I am facing the same issue.. battery bar stuck at 50%.. Sometime hitting at back restores the function.. but again goes back to same within a day or two.. very irritating..

The problem is not the software. the way you fix it is take off the back plate, remove all the tiny Philips screws and remove the hold down backing plate, and take a piece of paper and fold it 2 or 3 times and place it on the black foam piece that the battery connector is on the top of the battery, that's the battery connector connecting the battery to the phone electronic board. the problem is the connection is loose. what you are doing is creating a shim to push the connector in more. you could use electrical tape but paper works ok and you can control how much pressure to apply. do not use too thick of a piece for the shim or you would bulge out the hold down backing plate.

This actually fixed it, I got the battery of my phone replaced from the service center for another issue and got this problem after they replaced it. Wondering why they don't know about this problem they could have prevented it before it's released. First time I had to do this on my own as I'm frkn tired of going back to them. Thanks @eksine :victory: glad you visit XDA from time to time.

I must say : Asus Zenfone 2 is a peace of sh.. or maybe garbage.
I have problems with this phone from the day one.
Whatsapp,
battery (died after 4 months),
bad signal for internet (my other phones works much better),
software,
now the new battery is stuck on 50%
I promise that I will never again buy any product from Asus in my life, because this phone has destroyed my nerves.

Good find!!
I change a battery by myself and after that I stuck at the 50% too. After I read your post, I reopen the cover and found that the battery connector is really loosen and I apply your shim method to make it more better connection and it can read the actual battery percentage.
Thank you!

busted lcd?

Bought my sister a tab s as a gift.
Brother flew home with it, in carry on.
Was working fine, then "randomly" overnight decided to do this.
Looks to me like the LCD just killed itself, but has anyone experienced any like this.

its the infamous battery issue I think...
mine was like that several times before I decided to change the battery under warranty, and working perfectly since....

Interesting. Do you have any specific information regarding this issue that might justify a replacement from Samsung? Is there a self-fix?

Check on youtube for a guide on how to take the T700 apart it`s quite easy, check the battery connector, check the display cable.
The 8.4" has a lot of problems with connectors becoming loose, I think it`s because it can be bent without breaking inside pants pockets ect gradually loosening the connectors, You cannot do that with the 10.5"

Thanks John. Will send this along to my bro.

[Q] Screen flickering because of (top old and weak) battery?

Good evening,
Since a short time I have problems with my Tab S (10.5 LTE)
The display is now flickering so hard that the tablet can hardly be operated.
Initially, it was only after starting, but now it's getting worse.
Today I unplugged the connector to the battery and connected it again, just like the display flat cable, without change ...
Here I attached a video that shows the problem: https://www.android-hilfe.de/attachments/20180725_231014-mp4.648541
What could it be? The battery that makes the bend after 4 years or something else like the display cable or even the display itself? The battery for 20-30 € I wanted to change anyway, even if the current still holds pretty well. Could not explain to me why the flickering should come from a battery.
What do you think? Who had the same problem and could solve it?
Thanks and regards

Hi, I've faced similar problems.

Sadly, you may not fix it.
Hope this helps.

I was having this problem as well. I just reseated the battery in the device (power connector) and it seems to have gotten better.

Actually I'm having the same problem but on my Tab S2. It happens once the battery depletes below 30%. I believe the problem is down to the battery depleting so much that it can't power the display and/or higher clock speeds. The solution is definitely to replace the battery.

Thanks for the information.
I did that, replaced the battery and also the flex cable for the display but no success, the problem still persists
It seems that my mainboard is broken somehow or the touchscreen and the Tab S is not repairable anymore..
I will maybe buy an used one again or wait for the Tab S4

I was having this problem as well. I just reseated the battery in the device (power connector) and it seems to have gotten better.

Same.

Sadly my SM-T800 screen started having this flicker problem. Nothing helps. The battery connector "looks good", but then I don't have the eyesight to see what's really going on. The logic board on the T800 has a very unfortunate packaging where the battery connector is next to a heatsink. I certainly couldn't resolder it myself even if I tried. I guess this is the end of road for my Tab S.
