Hello:
My Tab Pro 8.4 has picked up an issue - it stops charging at 89%. Battery monitor - the one built in, as well as GSAM Battery monitor - show the charging increasing charge in a linear fashion to some 85%, then the rate gradually decreases, till the curve flattens at 89%. The phone still claims that the battery is charging.
I just discharged the phone fully, let it recharge - same behavior.
I did root the phone 2 days before, I wonder, if that has something to do with it.
Thanks for any info, Paul.

Hello,
maybe you need to recalibrate your battery. This can be done by deleting batterystats.bin. Search google play, there are some apps, that can do it.

Thanks for the info.
In desperation, I tried few things - first a Nandroid restore to the state just after rooting - that did not help.
Next I performed a hard reset. That fixed the problem for now.
I will carefully put back in the xposed modules I used, an see/hope that the problem does not come back.

Glad to hear that. Thanks for info.
Hi,
Did you find the actual cause of this?
I have a stock 8.4, non rooted and I find the same thing, I have attached a screen shot of the battery charge and dream. ...
Can anyone help with this please, the battery is bad enough without it topping off at 89%!!
Cheers,
Ian
Hi,
Has anyone else had this issue?
I let my tab run down to a dead battery, plugged it on over night and it is still only at 87% ...
Its driving me nuts!
I am not rooted, so don't see bow it's anything I have done, any ideas?!;
Thanks in advance

I do not have an answer, but I wanted to thank you for posting - your answer seems to indicate, that this is a issue not related to rooting.
While dealing with this, I have put back the stock rom ( but still with custom recovery on the device ) - which made charging work to 100%, then rooted again. With this config the charging worked for few days to 100%, till if failed again all of a sudden, getting stuck at 91% charge, and claiming, that the charging was ongoing for may hours.
While the charging was broken, I put on the CleanROM 1.0, and that fixed the charging problem again.
I do not see a clear pattern of this failure....

This does not "calibrate" anything. Any app that claims to fix the battery meter by wiping this file, is making a bogus claim. All the batterystats.bin files does, is indicate how much battery various apps/processes are using since the last charge. The file gets wiped ever time you connect the charger:
http://www.xda-developers.com/android/google-engineer-debunks-myth-wiping-battery-stats-does-not-improve-battery-life/
What you want, is to reset the "high" and "low" voltage flags related to Smart Battery. If there is an app that can do that, it might resolve your issue. Flashing a ROM also resets the flags (why you always need to do a battery charge/discharge cycle to get accurate readings every time you flash a ROM). So you might flash the ROM you are already on (stock?) and see if that helps.
But the issue itself is odd. If a higher voltage is achieved, I believe the "high" flag should automatically be reset. I shouldn't just "stop" at 89%.
Yes, I have (had) the same problem. I would use the tab through the day, then plug it in. In the morning, it would almost always be around 89...sometimes a bit more, others a bit less. I loaded battery doctor from the play store and set up a widget to kill all but a few specified apps (yeah, I typically try to avoid task killers, but this was driving me crazy). In my case, when I killed the apps, the battery would finish charging.
Theory (take it with a grain of salt as your mileage may vary): either the charger I am using or the tab has 'intelligence' that slows the charging down when it nears full, possibly to protect the battery. Certain apps running (sleeping?) in the background seem to keep the tab perpetually in a near-full charge state -- just enough of a drain to balance the 'slowing' charge. Every time I have killed the apps, the tab has quickly finished charging.
Again, this is just my experience. YMMV Good luck.
Try running the battery down to below 20% then recharge it. That should recalibrate the battery monitor.

I've been having issues with my 8.4 stopping charging only midway to 100%. If I unplug the cable and replug it, it continues charging.

i have had the exact same issue , mine stops charging at 54% , need to unplug replug and then it starts charging back again, also from 78% it jumped straight to 100, something is really wrong , how could samsung break something so simple and basic
I've got a very similar problem. It stops charging, usually at something like 40 or 50. If I restart it will continue charging, but not all the way, maybe up to 70 or 80. I think I tried just disconnecting the charger and reconnecting it and it didn't work but I'll try it again as that would be easier than restarting...
I sent it for service and after weeks of back and forth they gave me the old "it's rooted, so it's out of warranty".
F U Samsung. This piece of **** tablet has been messed up since day 1. First with the over sensitive screen and now this. Sony FTW.

You need to unplug the battery under the rear cover. Then plug it back in and boot up and charge it. Only way to fix. I never had issues again after doing that.

I have the same problem with my SM-T325 , i've tried everything on forums : reset, hard reset( vol menu button power button) nothing works !

Ps: I'm using genuine 2A white charger and even tried with Asus Nexus 7 charger 2A( ridiculously is that it works better than with the genuine samsung, the white one needs 5 unplug/plugs, with Asus Black charger only 3 unplug/plugs )

My battery has the same issue. I'm going to start charging my Tab Pro 8.4 with a lower amp/volt charger. I think the 5.3 volts & 2 amps puts stress on the internal charging / battery regulator circuit. The 5.3 volt makes the usb cable in the tablet reasonably hot to the touch. (a hunch)
Galaxy Tab Pro 8.4 Battery Replacement Video
Update: I scraped the 5.3 volt charger for a standard 5 volt charger @ 2 amps. It won't charge while in use but it does charge to 100% from 5%, powered off overnight. I also tested a 5 volt 1 amp charger (while slower) did charge from ~50% to 100%.
I would like to see others test this theory out.
Would also like to note, I believe Samsung included a 5.3V charger instead of a standard 5V so the tablet is able to charge while in use. My guess is the circuitry was originally designed for the standard 5 volts but once they saw the tablet's charge rate while on, they decided to throw in a different charger to make up for their mistake instead of a more reliable circuit design to handle the volt boost. More then likely they did tests to see if the tablet was able to handle the new charger but did not conduct the experiment for enough time to see the degrading results (faulty battery level readout).
If they knew of the issue in production they could have fixed the issue in a batch revision or recall or they flat out ignored the results and are in denial. Shame on Samsung if this is the case. Funny how they released the "better"("revision") Tab S while refusing to fix the Tab Pro. Now it seems to be biting them in the ass.
I still want to completely test this theory out and give it more time, but so far my assumption is seemingly correct.

I had another interesting experience with this tablet.... it charged 100% without notice that the battery is full(I saw this tiny little detail -battery full icon- ensures that it is really charged) restarted it to verify something and shock !!! the value dropped to 62% and the charging sequence stopped ...and even if it shows "charging" while I'm typing these lines, it dropped to 59% ). **** !!!
In the past week, my wife's 1 yr old Tab 3 10" has become flaky to charge and as of last night we can't get it to charge at all.
Tried several cables and different chargers around the house, no luck. The port is very loose so at first i thought maybe it was just worn out and wasn't getting a connection. Tried the freshest tightest cable i have in the house and couldn't get even a moment of charging so i've ruled that out.(or it's more worn out than i can imagine)
Saw a suggestion about the 7" model to disconnect the battery for a bit to resolve a similar issue. Gave that a shot but no dice.
After that I noticed something interesting.. one of my chargers stopped working when i plugged her tablet into it. until i unplugged it from the wall for about a minute, it wouldn't charge anything else. 3 times it played out just like that - charger works, plug in her tablet, charger doesn't work.
Then I plugged the tablet into my Macbook Pro and things got really fun.. it shut down instantly and won't power back up at all(i'll deal with that later on).
So,.. my assumption now is that there's a short in the micro USB port.. does this sound logical to anyone? Or could an issue like this be caused by something else that's not as fixable?
This is really disappointing because we've been generally happy with samsung products.. but this just seems too soon to have an issue like this. At least it's easy to take apart.
Sorry if this is a common issue that's been covered.. couldn't find any info relating to the 10" model. Thanks in advance!

well, if according to my understanding of your description, that is what happening to me now.
You can try my method which is working for me.
If you didn't mess your boot partition up. you can leave it drain for like hours to days *I have tried to leave it for 7 to 9 days... * and charge it again, keep charging about 30 minute to an hour when you see charging sign, then proceed to Section B if you brick your device. If you don't, just start it up normally and let it charge up to 100% before you discharge.
>Drain the battery by leaving it uncharged for hours to days
>Charge it on, you will see charging sign
>Leave it charge for hours
>DONE!
OR
You can replace your battery

And I guess maybe you have a p52xx (Tab 3 10.1 from samsung and not fom tmobile etc.) , remember to use 2.1 A x 5 v charger. Do Not use Laptop Power to charge your device . It may be a bug or hardware issue for this problem.

Thanks for the response.. I'll keep it in mind for the future. For now, this did end up being a bad usb port.. i ordered the part same-day on Amazon and had it swapped in 10 minutes. as soon as it was back together it was charging normally again. kudos to samsung for not soldering the usb port to the mainboard!

alright then, congratz for you got ur device back alive again
My N750 with stock ROM 4.4.2 refuses to charge normally. The led was off which being connected to USB wall charger. However it showed a grey icon battery for two seconds before the screen was completely off. I noticed the error message popped before this happened (quoted below). It said something related to Samsung power sharing software. Later on I found out the charging problem.
Power Sharing, You must download the app in order to control the amount of power shared. If you connect your device to another device with the Samsung Power Sharing Cable EP-SG900 without the app, the entire battery amount will be tranferred to the other deivice. Connect to Samsung Apps and download the application.

Strangely I did not use power sharing and honestly I don't know what it means and I wasn't doing anything or plan to do things with power sharing. The screen was a little shaky when the error appeared although seconds after that the phones worked normally except I cannot charge my phone. I understand that the phone might still have received current from the charger however small, especially when I charge it under recovery environment which is inconvenient to do. It took 4 hours to reach less than 30 percent under Phil'z Recovery method.
I tried to clean the micro-USB port with a small sharp needle but have no luck. It looked clean to me. I also wiped the data and did factory reset and tried to use different ROM. But still it won't charge. I also tried to use different cable and different AC Adaptor (Sony original charge 2.5 volt) which was working under normal condition but not anymore. I never drop my battery and always recharge before reaching 30 percent. That's my ritual as I read from battery University that frequent charging is much better than letting the Lithium battery goes down to near zero.
Any ideas?
I tried different ROMs to find the best. Is it possible that Samsung crippled the phone after so many reflashes? This is scary.
(UPDATE) The phone is NOT detected by Odin and flashing is not possible.

N750 refuse to charge
I HAVE THE SAME ISSUE WITH MY NOTE 3 NEO SM-N750 when i connect to charger message showing install power share apps its very simple to fix this charging issue take toothbrush and clean the charging socket with brush i did this and wowww its connected normally & phone start to charge without any issue
So I woke up this morning to find my Tab drained. I plugged it in for half an hour, then when I picked it up I noticed there was no charging indicator (the green liquid battery thing). So I thought maybe I didn't plug it in right. I reattached everything, tested the charger on another device, then plugged it back into the tab for about 2 hours...still no juice. I tried powering on and doing the reset thing. still nothing. I brought it to a Samsung service center and they said I have a faulty motherboard. Now I'm wondering how the hell that happened when I've been using this device for about 6 months (only 6 months) without any issues, no overheating or strange reboots or anything, and now just like that I have a motherboard issue? The kicker here is that they're charging 75% of the tablet price to fix it! What gives?! I purchased it from a non-samsung mall store so they said I can't claim warranty. I popped the back off and did the battery pull thing and tried to charge - still nothing. Did I buy a device that decided it was a lemon after 6 months light-moderate use?
Anyone else have this happen? It's never been dropped or anything and I was on stock firmware with nothing but root.
In the UK, If your tablet goes faulty in 12months your guarantee is with the place you bought it from, not Samsung.
John.
It's ALIVE! I thought I'd get a 2nd opinion on my Tab since the guys at the Samsung service center popped it open anyway. Went to a generic phone repair store, all they did was hook it up to this box thing, and it came back to life! The guy said something got corrupted and just re flashed everything to stock rooted. He charged me less than $20 and I have a working Tab again. Obviously the very first thing I did with my resurrected device was to call Samsung's hotline and report how this one service center was trying to scam me into buying a motherboard that cost nearly as much as what I paid for the thing brand new.
Some li-poly battery have an protection circuit built in, if the voltage falls below a certain level say 2.5volts per cell, it disables the battery, if you connect an meter to the battery you will get 0volts , you need an li-ion charger that passes an higher voltage that resets the battery and allows it to work again, I wonder if this is what happened.
http://batteryuniversity.com/learn/article/low_voltage_cut_off
John.
Did they connect via USB or to the motherboard?
@tinderbox could be...must have over-drained itself for some reason.
@ashyx I couldn't really see what he was doing since his work table was obstructed by a bunch of stuff and he had his back towards me, I just saw him grab this small black box, then minutes later he showed me that the tab was already powering on though couldn't get past samsung logo, then he went ahead and flashed to stock.
Reason I ask is I wonder if he used a jtag box to ressurect it by reflashing the bootloader.
If he did there must be jtag points on the board as it can't usually be done via USB.
Pity you didn't ask what he actually did as I'm intrigued now.
Did the box look like this: riff box

Exactly the same or just similar?
yeah i think so... it had similar ports, though not sure about the outer shell of it... i think it was smooth all around with no ridges or anything, just a little black rectangular box.
Sorry to revive an old topic, but i thought i'd do an update instead of start a new one. Tab S died again and I'm now convinced it's over-discharge, as I left it at about 20% and forgot to plug it in before going to bed. Woke up with the tab drained, not responding to any button combinations, not charging with any of my chargers that tested ok with other devices.
Instead of bringing it back to the technician, I thought I'd try mcguyvering the damn thing. I opened up the back, pried the battery terminals up off the board, lifted the battery out, and with a spliced USB cord hooked up to a powerbank, I gave the battery terminals a direct zap, inserting the exposed USB wires into the battery terminals. This took some trial and error as, I didn't know which wire was supposed to go where, but finally I saw the powerbank leds blink, indicating it was discharging into something. I held the wires in place for about 5-10 minutes, noticing some heat on the battery by then. I reinstalled the battery back into the tablet, closed everything up and tried charging again and...hey presto! the tab started charging. :victory: Let it charge for 2 hours and powered on like nothing happened.
disclaimer:
I don't recommend you defibrillate your device's battery unless you know exactly what you're doing and are fully aware of the risks. (I didn't know what I was doing at the time but I was so frustrated at that point I didn't mind if the battery blew up in my face.)
Mine just dead last night while CHARGING (turned off at 13%).....
And refused to turn on till now (still charging and both warm (charger + tab)...
I even plugged an ampere meter to really know if its drawing any or not (it is, at 5.2V 1.7A for 15mins)...
And still no luck
Samsung's device become more ****ty each generations..... Esp the battery...
This one is the replacement batt they gave me after 2mos of usage for infamous Tab S battery issue...
I saw a video on youtube, a guy had a dead 10.5" T1 he took the back off and connected an 1amp microusb charger pcb to connections directly to the battery under a piece a tape, I bought a couple of the microusb charger pcb`s from ebay for 0.42p each in case mine goes dead.
EDIT: I found the video.

This took some trial and error as, I didn't know which wire was supposed to go where, but finally I saw the powerbank leds blink, indicating it was discharging into something. I held the wires in place for about 5-10 minutes, noticing some heat on the battery by then. I reinstalled the battery back into the tablet, closed everything up and tried charging again and...hey presto! the tab started charging. :victory: Let it charge for 2 hours and powered on like nothing happened.
disclaimer:
I don't recommend you defibrillate your device's battery unless you know exactly what you're doing and are fully aware of the risks. (I didn't know what I was doing at the time but I was so frustrated at that point I didn't mind if the battery blew up in my face.)

Samsung tablets only have issue with battery connectors. The white connector with 6 wires has loose connection, the black connector soldered to mainboard has cracked solder joints. New battery won't solve problem if you don't fix these two flaws. Resolder the battery connector will fix most of problems: not charging, reboot, flickering, auto shutdown.
I posted more details in the threat: flickering screen.
so the problem is Samdung's QC....
anyway no more somedung, I switched to Xiaomi Mi Mix, still preordering from China.....
You have to watch these chinies owened tablet and phone manufactues, they have been found to come with built in spyware, sending copys of all your texts ect back to china, it`s been in the news that last few day`s
Lenovo notebooks had a spyware app and Lenovo had to issue insturctions on hot to remove it once it was found.

That's OK, I can scan and remove all those spyware.
Still its better to have it properly supported with actual updates (older phone still got all UI + android update, hello MIUI 8).
Rather than using phone without proper software support....
Tab S - buggy and prolly the last MM update
Note 3 - useless LL update, very unstable, consider alpha
Note 8.0 - buggy last KK update, switched to CM13 and happy with it
Hi!
I bought my Sony Smartwatch 3 about two months ago. I've always updated the watch and now I'm on the latest build MWD49B.
I don't know precisely when the problem started, but for sure also before updating to the latest build it already showed it.
Basically if the watch is turned off it won't charge and it'll overheat a lot. I mean it maybe charges at an absurd rate, like from 60% to 100% in about 4 hours.
I tried changing charger (1A and 2A) and charging cable, but it doesn't change. It's like stuck in some way. The funny thing is that when it is stuck in this state if I turn it on (with the same chargers and cables) it starts charging fast (normal charging times) and funny enough it gets colder than when it's turned off charging (I mean slightly hot but colder than when it's stuck).
Do any of you has this problem?
Could it be a SW problem too or just HW? I haven't tried to reset it yet, but would rather lose time in resetting it and reinstalling all my stuff than losing time in the RMA process and waiting time to have it repaired, even because thinking of running without it makes me feel already mad!
I also have MWD49B and I'm charging my watch with (AFAIK) a charger which was bundled with Xperia PLAY docking station. Its output is around 500mA. Sometimes I was charging the watch with EP880 charger (output 1,5A) and I was charging it with BlitzWolf charger (output 2,4A). I've never had any problems with overheating and I pretty much never turn off my watch even when charging.
The problem is that some watches (especially the fresh ones from 2014 with glossy grey cap on microUSB port, not the full rubber ones like my watch have) might have faulty battery. If it overheats, charges 4 freaking hours... well it's REALLY long... my 500mA charger charges my watch up to one hour and I have no problems at all...
If you still have warranty, I'd suggest returning the watch, this overheating might be dangerous.
Hi!
Thanks for the answer.
My watch is from an April 2016 batch (written on the box), and it's one of those with the rubber cover on the charging port.
Just to be clear, if I charge the watch when it's ON, I don't have any problem and it is charged in less than one hour, the overheating problem and non-functional charging is present only when the watch is switched off and it is charging.
Me too...
I bought my Sony Smartwatch 3 about one years ago...
Whan I first charge it from PC's USB port , the same problem with you..
I don't know why...even I reset watch , it's the same...
So..I always charge the watch when it's ON...

I have the same, "new" batch, with rubber cover on USB port.
I'm not sure if I missed some of your text from the original post or you edited it. I'm talking about switching the watch on so it does not overheat.
I've noticed my watch behaves exactly the same! If it's turned off and charging - it's hot like hell and not even fully charged after two hours and if turned on and charging - cold and fully charged after like... one hour.
Strange because on earlier Android Wear builds everything was ok.
Same over here.
But I didn't try charging it while it is running.
But when it's off, it only charges up to 75% and gets insanely hot. Then, when used it drains normally until around 50%. After that, the battery dies within 1-2h
I also never had any issue with the battery before the last update.

I've had this exact problem. One thing I discovered is the battery will stop charging when it reaches a certain temperature. Try placing a fan to blow directly on it while it's charging. This has worked for me.

Same problem here.
I've got the SW3 of 2015 vintage (it does have a cover over USB - I thought they all did?)
Since updating, if watch is off while charging it gets very hot, charges very slowly and never to 100%.
The solution is simple enough - charge it while OS is running.
If the watch is out of juice: Start charging, let it get enough to boot and then again allow it to complete charging with Android Wear running. Then charges normally (about an hour) and doesn't get hot.
My feeling is this is a software issue too. I'm running M1D63G.
Since we all know batteries don't appreciate getting cooked, I'm wary of leaving it charging for long when off, I'm betting it will cause battery damage eventually.
Conspiracy theorist's might even suggest it's Sony's way of ensuring our SW3 batteries die, so we're ready to update to the SW4 - I'm not that cynical.
Hello everyone, here's the matter don't know where to ask it so this thread is similar...
I have 2 Sony3 watches, one with screen partially broken and the second I got it secondhand with a charging base made by the previous owner.
The watch that came with the charge base it always has the charge icon on screen even if it's not charging, sometimes if i reboot it dissapears but most of times it STAY :/
if i turn off watch vibrates and start "charging" all alone without connecting it so i don't know what to do with that cause it obv drains battery and its never really off...
Second thing, my old watch with broken screen worked well since i plug it into that base.... then is doing the same as the other watch, charging forever without charger seems like the base charge illness has affected my old watch too... XD
So pleaaase anybody know something about this? i've restarted them several times and with pcCompanion and the icon remains maybe a custom rom will solve or is hardware issue?
I am using may sony smart watch 3 for long time and i kept it for some month after then i carry it and begin to charge it but it will only show sony and then will not proceed i kept it again after i carry it i plug the charger and it only vibrate
This watch needs to be recalled or have an emergency firmware update. My smartwatch 3 overheated while plugged in overnight and melted apart. Thankfully it was on a metal computer case and not some paperwork. This annoyance has become a real safety issue. It's a shame because I loved this watch otherwise.
Just a general FYI to all of you, use a USB Port or a charger that charges slow and always turn it on when you charge it.
Our watch is really different compared to anything nowadays. It shouldn't but still charges faster than it (should) be allowed.
My Watch is still with it's first Battery and it holds for at least a day, just be careful
