Just re-seated the battery and I dont think its a placebo effect. I can definitly say the battery life is much better and I can make the battery go all the way down to 0% without having any of the reboot issues I used to have previously.
[Galaxy Tab Pro 12.2, 10.1, 8.4 General] XperiaZ77:
same problem here....unbelievable Samsung can get away with this problem, this a real problem and we should all demand our money back......First i had the battery problem and still having them and i refuse to open up my tablet to reset it. The was my first samsung but also my last. Back to Sony! i also have extremely lagging issues and the screen doesn't respond anymore...like a minute later it lightens up..smh..........i'm trying a custom rom maybe that will solve the problems, if not, no more samsung.

Thanks for sharing bro!!! Totally worked!!! My battery charged only to 18 % before this procedure and now is working properly again... Stupid Samsung...
[Galaxy Tab Pro 12.2, 10.1, 8.4 General] AndyYan:
It seems most people are getting positive results... But if you care about the looks of the tablet as much as I do, or if you bought your tablet fresh, I'd discourage you from doing it.

Mine is only charging to 93% when powered on (but 100% when powered off), so when I saw the thread 2 hours ago I thought, "why not?"

I pried the back cover off using a typical set of disassembly tools, but the glue and pins around the tablet's upper and left sides are too damn strong I had to use some additional force, which caused some small but visible damage on the rim of the device. Furthermore, just as some others reported, when I complete the process and put the back cover back on, the parts around the IR port and the right-up corner won't close tightly for WHATEVER reason. I even applied some 3M adhesive strips around the places and still. I also have a protective case to cover that up, but that will not change the fact that it's there.

I've yet to see the effect of this process on the battery performance of the tablet, but the dents on the rim and the gap around the IR port already deemed it unworthy for me. Take some consideration before diving into it.

Just did this method. I used a thin credit card-like tool I had lying around. It took me maybe 10min at the most without any incidents. The case snaps back together tightly with no bulges/space in between. I haven't tested battery life yet, so we'll see if this works.
[Galaxy Tab Pro 12.2, 10.1, 8.4 General] storino03:
So I've had this done for nearly 2 weeks. Battery life (reporting anyway) seems more accurate, which leads to better battery life. Wifi/Bluetooth seem to be slightly more wonky (disconnecting from router/speaker) and having to cycle them on and off to reconnect. Other than that, haven't noticed anything else.

I saw one thing. When charging via USB - the "red cross" appears, BUT IT STILL CHARGES! (But like 2-3x slower).

IN 5MINS FOR ME IT GOES LIKE 2-3%!!
[Galaxy Tab Pro 12.2, 10.1, 8.4 General] thecdn:
Reseated the battery about a month ago and the battery life has improved noticeably.

It also fixed two other issues I was having with my tab:

- It wouldn't charge while off - had to be on. That is no longer the case;

- Also, I used to have to press the on button for 20-30 seconds, often several times, for it to turn on. Now it turns on in a few seconds like a normal device should. This being fixed is almost as good as the better battery life.
[Galaxy Tab Pro 12.2, 10.1, 8.4 General] Swizzy88:
I did this about an hour ago after I noticed !y tablet not charging past 90-96% and discharging quicker than usual with maybe 5-6 hours SoT compared to previous 8h+.

Took me about 3 minutes and charged to 100% without issues. Currently at 94% with 40minutes SoT already.

I suppose you get used to it when the change is slow, I forgot how good the battery used to be.

Thanks for the advice and I'm genuinely curious as to how many other Samsung and non-samsung devices are affected.

Edit:

As you can see almost 24h since charge, 7.5 hours SoT and still 18%. Before it would have been dead after 5-6 hours SoT
[Galaxy Tab Pro 12.2, 10.1, 8.4 General] republicano:
Just tried this last night, battery at 5%, popped the screen off with a guitar pick, resembled it and battery was at 40%,

Battery last a lot longer now, and seems a bit less glitchy.

It was discharging on some chargers, and slower on others,

Android stated it would take 12 hours to charge.

All fixed now, thanks.
[Galaxy Tab Pro 12.2, 10.1, 8.4 General] AustrianAtheist:
Hey guys, i had the same problem and followed all the instructions, now that i have reseated the battery, it shows me that i have 71% left, before i reseated i only had about 50%.. is this normal or does it show a false number now?

And it still shows me that i only have 2 hours left with 71% battery... does this change after a complete discharge?

hope you can help me
[Galaxy Tab Pro 12.2, 10.1, 8.4 General] Swizzy88:
Just do a full discharge/charge cycle. Sudden jumps in battery % can mess with the estimates and whatnot.
[Galaxy Tab Pro 12.2, 10.1, 8.4 General] WBFAir:
Hello all

I am having a problem where I really don't think my battery is "not" lasting as long as it should, but it seems to not read the amount correctly.

Basically what happens is around where its reading 60-70%, the device starting going into this restart loop of getting almost fully started, but then self restarts, which will be fixed right off if I plug it into a charger, an of course will stay fine once it gets charged more.

Note that during this restart loop, I really can't do much other then plug it into a charger to get it completely started an thus able to do something with it.

So don't know if this reseat thing is really the right place to post this, but was just hoping someone in this thread might have some advice?

Note, I did try the trick of holding the power button down for what I hear is called a soft reseat, but that didn't work.

I have also read about the let the device 100% die an recharging in certain ways thing to recalibrate, but is kinda hard for me to try that as the device never just runs down an dies, it just goes into that restart loop.

So does anyone have any help or suggestions?

Thank

Truly unbelievable what a mess Samsung made of this. I'm now sitting here with a tablet which simply doesn't charge anymore while being powered off. SHOULD I get it somehow back powered on, it will charge just fine to 100% and never have any issue with charging. Until it runs out of juice again. Then it takes me hours of letting it charge (nothing on the display except that empty battery icon), reseating, charing, etc. in the hope of bringing it back to life. Seems like I'm out of luck this time as I've tried everything for over a day. Can't even give this piece of rubbish away in a state like this. Never ever another Samsung device, lesson learned! :)

when you do get it to charge does the battery last awhile?, if not it might be possible the battery just went bad and needs to be replaced
[Galaxy Tab Pro 12.2, 10.1, 8.4 General] elaurens:
For whatever reason I managed to get the tablet powered on again and it charged to 100% just fine. The battery is discharging at normal speed (hours of onscreen time and days/week of standby). The thing is, this issue started happening with its original battery and it continues to do so with a new OEM one. The only thing I can do is to make sure I power it off (while still having a charge) if I'm not planning to use it for some time. Seeing how many ppl here have charging issues with their tablets, I'm still putting the blame on Samsung. Anyway, I appreciate that you kept replying to my rant :p
[Galaxy Tab Pro 12.2, 10.1, 8.4 General] Rhodesfreak:
I just realized that at least on my tablet this battery issue is software related.

Thanks!

Just wanted to say thanks, it is so simple and it fixed all the issues I had previously (random reboots, low battery life, not charging fully...).

All the best.
[Galaxy Tab Pro 12.2, 10.1, 8.4 General] osssinator:
Here is what I did for my not fully charging battery.

Just simply let your device to fully discharge until is swich off. Then put it in the charger but not switch it on. After it gets fully charged switch it on, and again do this procedure 2-3 times.

This is what helped me to solve this issue. Now my battery is changing fast and complete to 100% every time.
[Galaxy Tab Pro 12.2, 10.1, 8.4 General] Sicron:
For the past two weeks or so, the issues started to return. My tablet would only charge to about 80%, so I redid the procedure just now. My battery was at 24% when I turned it off, popped the back off (if you are careful, this really seems to be the safer way), took the battery connector out of its socket and placed it back it. After I turned the tablet back on, the battery was at 44%. So it really seems to be a battery calibration issue that returns after a while. Slowly with every recharge, the battery calibration isn't reported correctly. I was getting about 5-6 hours of screen-on time the past couple of months. I will report back in a couple of days to see if that has improved as well (should get 2 hours more, easily, now that I have regained 20% of lost battery life.)
[Galaxy Tab Pro 12.2, 10.1, 8.4 General] Mossey:
Use Advanced Battery Calibrater!

I was having the exact same issue! It got so bad, when I placed my tablet on charge it was getting discharged. I installed the app from the title, and it worked. Getting 100% charge and much longer battery life. Much easier than tearing apart your tablet. Common sense, makes me think that removing the battery, is like hard resetting battery tables, and the same thing can be done with software!

Video about how to open the back cover was deleted

Hello folks. I'm experiencing some battery issues and would like to try to reseat the battery. As recommended I'd like to open the tablet through the back cover but the second video link showing the instructions is down. Could someone please instruct me on how to open it. Thanks in advance.
[Galaxy Tab Pro 12.2, 10.1, 8.4 General] Sicron:
It is not that hard. I personally use the method which takes of the back cover. I open the SD cardslot's cover, and then take a hard piece of plastic, a plastic ruler. You might also be able to do it with a rigid plastic (credit)card or something, anything that doesn't flex too much should work. You can also use a thin piece of metal such as a small screwdriver, but you will absolutely damage the silver trimming. Just insert it between the SD card slot and the plastic backcover carefully and try to wedge it open. You will need to apply a moderate amount of pressure by turning your piece of plastic. At some point you will hear a click, which means one of the tabs of the back cover will have popped open. Just place your piece of equipement a bit higher and keep repeating the same motions until the entire back cover is off.

Be careful around the USB port and the headphone jack, the cover is hard to open up around them and you may break a tab off if you apply too much pressure. If you are lucky, there is a chance you won't have to take off the entire back cover to get the battery connector out of its socket.

battery woes...off to the repair center

I will say this for Samsung, the 12-month warranty (I'm 6-months into it) on my GTP8.4 was very handy indeed. The whole process could not have been simpler and the turnaround time was only about a week, I should receive it back Monday. These three items were listed as work/parts performed:

DATA LINK USB CABLE

11PIN CON FPCB

BATTERY T4800E 4800MAH

I'm guessing that is a new charging cable (as in the one used to connect to charger), new USB connector and new battery.

If you have one under warranty and you are having issues, if it's not stock, get to stock and send it off. If not under warranty, the battery tips on here and on youtube might help

I bought a new battery several months ago as I assumed i had a defective battery, the problem was fixed and I was happy. Recently I was experiencing the same crazy battery drain issues again and I tried just "reseating" it, and 1 day in its working brilliantly. I couldn't disconnect the battery without unscrewing, without feeling like I would break the connector, which was not a big deal to me as I'd done it before. It was also much easier to get the back off the second time. Hopefully this is a permanent fix, but I am considering selling my tab pro 10.1, but don't think I can replace it with something equivalent for a similar price.
[Galaxy Tab Pro 12.2, 10.1, 8.4 General] NickosD:
I will be getting mine to a Samsung service in my town. Having the Knox 0x1, won't help but I will ask if we can open it with the tools that they have there. If not, I will keep my tablet connected always with a battery bank which is much cheaper than buying a battery. I will also try to order the tools to open it myself.

I made it with credit card. I can't remove the connector at all. I have to push the connector or do I have to pull it up? If I unscrew the battery, will it be easier?

Sent from my bacon!!!!!
[Galaxy Tab Pro 12.2, 10.1, 8.4 General] Sicron:
You need to pull the connector up. I used a small philips screwdriver and placed it underneath the wires, then I applied a really small amount of force to lift the connector up. I do this multiple times from both sides to slowly lift the connector out of its socket. Though I must confess, this is probably not the best way to do it (in regards to not ruining the wires). If you unscrew the battery and take the battery out while also lifting the connector out of its socket, it will be much easier.
[Galaxy Tab Pro 12.2, 10.1, 8.4 General] NickosD:
Do I have to remove that green sticker at the top of the connector? I unscrewed the battery but it won't come off. Does it need to put some power to do pull it?

I to had the 90 or 96% max issue but could 'solve' by replugging the power cable and some time later it appeared as 100% but battery life was always around 3-5 hours sot. Did the reseating via the backside with a plie tool also used for upgrades in my Macs and no damage done. First attempt looks great after charging: 86% left after 24 hours and 1hr24min sot. For battery drain in standby I use DS Battery save pro otherwise the standby time even on Marshmallow (resurrection v5.6.1 rom) is still poor.

I have the Tab S 8.4 and some incosistent readings from the battery as well. SOT is debatable (3-4 hrs with mainly Candy Crush). Get the best battery performance on custom roms, but went back to stock about 2 weeks ago. Now I sometimes have the issue of not being able to charge beyond different %. Sometimes it wont go beyond 88%, last night it refused to pass 91%. This behavior is since being on stock.

Did any Tab S user ever tried this reseating?

Any suggestions?

Yeah the battery is good, what happens is the connector clip metal claw like pins warps overtime from heat making it get poor contact to the main board, when you re-seat it it usually re-positions the pins and it's all good again .

btw my battery still holds 4800 mAh (according to my USB Ampere reader charging from 0-100%) and it's 3 years old so they are quality batteries, just use a poor connection method, but I guess it's better then having a soldered in battery :)

you can see how the connector works here for an inside view, you can see how the pins get mis-aligned

I should note, though, that it took several tries before re-seating the battery had any effect -- what really seemed to work was leaving the battery disconnected overnight (1-5 mins was not enough). Not sure why this is the case, but all is well now.
