[Q] S tab 10.5 battery issues - Galaxy Tab S Q&A, Help & Troubleshooting

After Rooting the t800 I have had battery issues charging takes too long so far I have left my tablet on charge for 6 hours and battery is only 15% I have checked all plugs cables they all work fine. What can be the issue? The knox has been tripped to 0x1 also I have hard resetted the tablet back to original firmware...still same issue. When I plug in via usb cable pc or laptop I get a red cross symbol before I never did get that. Can I send it back to Samsung for replacement repair? So annoyed! should not of done a root

This tablet will not charge using a USB port on your computer and never has. The rooting thread clearly states that rooting will trip Knox. Rooting should have no effect on your charging via a wall socket. I have a rooted t800 and it charges fine.

Trying to charge via pc or laptop isn't going to get it anywhere due to the lower output.

[Q] Not charging/No computer Responce

My ATT Note 2 took a turn for the worst when I went to charge it tonight. I installed the Jedi-x rom about a month ago and had a couple issues every now and then getting it to charge, but nothing a reboot would not fix.
Now I can not get it to charge at all or connect to my computer.
My fiance has a note 2 as well, her cable/battery/and everything will not charge it either.
I have flashed Blackout
I have flahed the stock i317 kernal
i have reset battery cache in recovery
The device does detect when in download mode. Also with the phone off, when plugging in the power cable, the little red light does flash faintly. What would I have to flash to get back to 100% stock or fix this issues with not charging?
Update: Did a full Odin Firmware reset and still was not able to get a charge or any activity computer wise besides in Download/Odin mode.
Have you tried re-installing Samsung Drivers?
Also does your GF have the same issue with her Note 2 not charging on your PC?
When you plug your Note into another PC, does it charge?
If not, then it might be your charging port (on your Note 2)

Sorry, it's late when I was typing this, her's DOES charge. I used her phone to test my cable and battery, and it does work. What gets me is download mode works. I don't know if it's a separate thing for charging, but it worked fine the other day.
No other PC charges
No other wall place charges
No other cable charges
No other battery charges
Sounds like the charging port, a known issue with the first note. I would be taking it back to where you bought it.

Yeah seems like a defective charging port.
Or make sure the Micro USB port on your device is clean. You can try some compressed air to make sure there’s no dust in there blocking the connection. If it doesnt help, then return your device to the Place of purchase for a possible replacement.
If it's the charging port then you should be able to test it by moving the cord up & down and back and forth and it should hook up at some point.

Did what all of you suggested, and ended up sending it back. Then last night, I was like "eh I'll try it again" plugged it in, and it instantly started charging. So, whatever, I sent it back anyway. Thanks for the ideas guys.

[Q] Note2 not charging, connect(ed) to PC.

Hi,
Yesterday my new (~2 months old) Note2 stopped charging. tried 2 different chargers, 2 different cables connected to PC. No reaction (no beeps, no led, battery icon not changed to flash).
Tried removing and putting the battery back in. No change.
On the other hand, when connected to the PC, the PC identified the connection and allowed file transfer. Later the battery died completly. I succeeded in booting to download mode, and again PC identified the USB device.
Switching the phone on with no battery gave no results either (would not turn on).
This leads me to a conclusion that the USB port is probably OK. Could it just be a dead battery? (according to its label, the battery was made on Nov 29th, 2012).
I will be able to switch battery tomorrow with another Note 2. Anything else I can try till then?
Using custom recovery and stock rom.
Thanks in advance,
Idan

Yeah, with or without battery... no reaction from the phone.
Have you tried a lower powered device to see if that works? Some usb ports don't have full power output, as some laptops portray.

I've tried 2 USB ports on a desktop PC. didn't work.
I've connected it without the SIM and SD to an old nokia charger (0.7ma), no sign of a change but after ~ 1 hour I noticed the red led turned on - turning the device on showed 44% charged.
Now I am too puzzled. any ideas?
This is exactly what happened to me. .. it was the motherboard. I brought an external battery charger, charged the battery full so I could use the phone. Then used triangle away and odin to flash stock rom, and sent it in for warranty service. This seems to be becoming a common fault with the note 2 now....ive seen a few thread recently.

Hey there, my sgn2 n7100 had the same problem before, I tried everything, even disassembled the phone apart, but it was still won't turn on or charge, won't be recognized by pc or Mac. One day when I repaired my mom's iPhone 4 touch screen, I found out that the USB port was so dusty. I thought may be it's all because the USB port was dusty then I picked up my sgn2 and used a soft tooth brush with a little pure alcohol to clean every corner of the USB port. Guess what? After 15 minutes I connected my phone with the USB wall charger, my sgn2 just started to charge again. Trust me guys, try to use a soft brush to clean the USB port before you give your phone to the repair store or somewhere else. Good luck!! Hope it helps.
Same here, i manage to purchase note 2 for 300 euros! And when I put it to charge nothing!I went to download mode and then turn it on normal and its charging! Also happend the same with my s3 so eighter its a charging problems or seems to be one software issues
Sent from my GT-I9300 using Tapatalk 2
@scufutz I could guarantee the symptoms described by the OP is NOT software issue, as I have an N7100 with same problem and I managed to flash new kernel and still it does not charge even powered off. Download mode connects perfect.
I'll check if this cleaning method, or if its a circuit prob.

[q] sending rooted note 2 to service!

Hello everyone,
i was playing real racing 3 on my gn2 and had 10% battery, wanted to charge it and realized it was not charging anymore . turned off, took battery out waited a bit, tried again but no luck. tried with another charger, no luck. tried with usb cable through pc but got again the same result. phone was not recognizing any cable connection and after trying all these i was only 4% on the battery now. found out it was a hardware problem and googled the net, saw many entries about (not) charging problem and decided to send to service but it was not possible for me to flash any stock firmware since usb connection was not possible. i couldnt do anything else because battery left was only 3% then...
so i had to send it to service as is... and of course they denied repairing it within warranty as they found the custom binary count and asked for 243 euro to repair it
now i will get the phone back, of course un-repaired and i ordered an external battery charger. i will be able to reset the binary count by using triangle away but i cant use any software (odin, kies... ) to install back the official firmware.
now my question is; is there anyway for me to install stock rom on it(maybe mobile odin??) or to send it again to service after resetting the binary count and pray for them not to save my imei number and not check my firmware on the phone but to check only the binary count???
thanks in advance
you could Flash the stock Firmware from Mobile Odin and and user Triangle away .it will show as Official , after that do a Factory reset so it would remove all the Root folders.
Here is the link
N7100XXDMC3 N7100DBTDMB1 - Germany Download here- India Original Source
I don't believe it is simple charging issue, if so USB port is hardly costing >10$
they gave you estimate 243 euro, simply suggests you needs Mobo replacement.
Anyway try managing foe extra battery and check whether it device boots normally OR do you able to flash anything.

thanks a lot for the answer, i will first use triangle away, i guess it requires root so after flashing official firmware it wouldnt be possible, then the stock rom via mobile odin.

at first,thanks for the answer,
device was working correctly before sending it to service everything was fine apart from usb connection issue. would u suggest me to buy the usb port and replace it by myself if they again dont repair it?
First try getting battery charged, then it will be easy to diagnose whether it is usb issue or something else.

Possibilities are if you replace it yourself locally then you will Void your warranty so better to try all other Possible ways
this may sound a bit stupid but it happened to me once.
i wanna as OP... after completely draining ur batt... u plug it in to charge for how long?
here's what happened to me. forgot to charge my phone overnight... went to work with 40% charge... by 1pm totally drained my battery. i was on field that day with no access to charger and constantly on the go from 1 customer's place to the next... only managed to charge it when i got home at 10pm.
after i plug it in... totally no reaction. as if charger is not functioning. i left it plugged in.. after 5 minutes or so (im not sure how long.. i went for a shower) when i got back to my room i see it charging with the red battery on the screen... after it got to around 30% i switched it on and let it continue to charge overnight.
so y not try plugging it in to charger a bit longer... see if it starts to charge. it worked for me.
for my case, to prevent this from happening again i got myself this
http://www.samsung.com/us/mobile/cell-phones-accessories/EB-H1J9VMAGSTA
but i got mine in white. comes with an extra original battery. so in the event i forgot to charge it overnight i can quickly swap the battery.
give it a try. no harm trying

[Q] Sprint Note II Charging Issues.

Alright, I'll try to be as brief but detailed as I can.
I just got my note II 3 days ago. I used what little charge it had out of the box until it died, and plugged it into my computer to charge it overnight.
I woke up and it was fully charged. I used all of the battery and plugged it in to charge the next night as well. only this time, I woke up to find it hadn't charged a bit.
I tried to plug it in to a different charger, and I saw no charging icon. I rebooted the phone, and I got the charging logo. it only charged for about 10 minutes before it stopped charging. I tried to reboot it again and got the same issue. so I spent a while trying different chargers and cables until it was totally dead.
Now, when I plug it in I get a gray battery icon with a loading circle in the middle, and then it goes away. I tried leaving it for several hours like that, but it didn't charge at all.
I read on several sites, including this one I think, that it might be a software issue. I tried flashing to a stock recovery rom with Odin but that didn't do any good.
the weird thing is, I can get into the recovery menu, and let it sit there for hours, so the phone IS receiving power from the charger. it just wont charge!
I took apart the phone to check out the solder on the connector, everything looks perfect. I even sprayed it out with electronics cleaner spray.
I'm not sure what else I can do besides get a new battery, but I mean, this one is brand freakin' new!
What exactly does this battery icon mean? I can't find any info on it or anything.
btw, I still can boot into android, but it instantly dies.
thanks for any help!
I had the same issue about a month after I got my note II. I ended up having to take it back to the sprint store. They ordered a new one for me and I swapped it out once it arrived. It didn't cost a thing and I had a backup phone to use while my phone was dead. Check with your local store and see what they can do for you.
I bought my phone from ebay (new) so I dont think that will work : (
some updated info though, I charged the batter using a friends note 2, and it charged fine. I stuck it in my note 2 and plugged in the charger.
it says its charging on my phone. I get the charging symbol and everything, but it just doesn't charge. I'm really starting to think this IS a software issue. maybe I should try a custom rom.
Factory reset could help.

Note that at stock the phone kernel is not written to make actual use of a 2A Usb line. IIRC stock kernel limits to sub 1A.

[Bricked] Flat battery, Won't charge, No recovery, No root

Hello all,
I'm at my wits end to put it lightly... I have the P-605, I was trying to flash ng1 official firmware through Odin v3.09, which the file in question, I have used a few times before so it isn't a bad download.
It got about half way through and died. The tablet still boots to the 'firmware upgrade has encountered an issue screen', I can still enter download mode. One major issue I can't charge it and i have no recovery [emoji22] its now dead flat.
Even with my 2.1Amp tablet charger it boots for a few seconds and dies. I've tried multiple cables and USB wall chargers as I thought that may be the issue all to no avail! I am completely lost. Any help would be muchly appreciated
What was the firmware before you flahed the stock ng1? cm11?
Have you try to flash recovery with Odin, don't let it boot up and see if you can boot into recovery.
Did you try to flash with low battery juice??
The prior firmware version is unknown :-/ but it was X KAT v3. I did try to flash recovery but it resets before it gets it done, if I hold the PWR, VOL+, HOME the screen seems to light up stay black a little longer than if it was going to the firmware issues screen then go to 'firmware upgrade has encountered issues' screen. It seems the longer I keep it off charge the longer it takes for it to reset next time its plugged in, so I will leave it for a hour and try to flash recovery. I didn't know what the battery was at 'probably very low' as I haven't used it in yonks and it was already in a bootloop from flashing X Kat v4.0 incorectly otherwise I would have charged it
I'm thinking about taking the battery out and manually charging it with a old USB cable. From pictures on the internet the battery has 2 red 'positive' 2 black 'negative' and 2 green. I'm unsure of what the green cables are. Is there anyone that can shed some light on this?

Hi,
have a look here for the USB pinout !
The original cable uses only four of the micro usb pins. The second ground pin is missing. This can be used to put the device into certain modes. I used different cables, all with five pins, no problems, but it does not mean, that the fifth pin was wired in these cables. Batteries have an internal security circuit which cuts power vis a polyfuse, if the voltage drops too low. The fuse should be re-armed when connecting the device to the charger, although the device may not recognize its own battery. Let it charge for a while, that the fuse doesn't blow again when disconnecting. Plug in again to charge fully. Some devices have a design fault which makes them unable to recover with a discharged battery. Charging Voltage is not 5, but 3.7v! The additional cables at the bsttery are either for a dumb temp probe, or a bus to communicate with the security circuit. The latter maybe impossible to charge externally. Otherwise you probably need some professional charging station, which can handle all sorts of Nimh and LiOn batteries AND have to make an adapter for the custom battery plug. Too much hassle, right?

Get one of this usb filter charging adaptor and use your pc to charge it. This also allow you to charge your tablet using any power source like PC, car charger etc... you will not see the X mark when using your pc to charge.
http://www.amazon.com/gp/product/B007IXBTCK/ref=oh_details_o02_s00_i00
This adaptor adds Apple signaling for charging currents above 0,5A. If the current charger won't support Apple stuff.
And yes, I suspect that the Note expects the Apple signal for 2A iPad charging.
I don't know whether there are any supported charge modes in between, like 900mA, but it charges from a standard 500mA usb port, but only in soft-off and idle deep sleep, and ultimatively slow.
But then, since the KK update, some people's Notes charge only during active state.

I have the same issue.........!!!
I'm lost at this point and dont know what to do.
Any attempts at flashing appear to be useless as there is now zero battery and it wont charge.
It boots straight to 'Firmware encountered a problem screen'. I can get it to the download screen.
It also made it 47% of the way through a recovery via kies, but i think the battery issue caused the failure.
If the cable is pulled out while in the firmware encountered a problem screen it instantly dies and wont start. It wont start unless the plug is in........
Anyone??? Please???
With zero battery, you can't perform any maintenance requiring a usb connection.
Without OS and/or custom recovery, i don't know any advice.
ADB and probably Fastboot operations can be performed via wifi, while the thing is at the charger, but in brick state this won't help.

Maybe the Note froze and drained the battery till it's safety circuit kicked in.
Then you should leave the Note charging for a while(hopefully), to reset the circuit's fuse and get enough juice to not trigger it again immediately. Normally, after unplugging and replugging, the battery should get recognized again and charge normally till full. Monitoring charge in Off-State requires(only) a working kernel, i think.
It also could be a defunct usb jack or just the connection with the main pcb is loose, which is typical for the Note, like loose display and backlight cables.

Thanks Lecorbruiser.
I have had the unit aprt a few times to verify battery connections and all ribbon connections on the boards are ok.
Im note sure of the safety circuitry uou mention though.
I have also power the device up with out the battery plugged in at all. So i know the supply is there. Maybe i have run the battery too low to recover?
Sent from my SM-G900I using Tapatalk
The safety circuit is in the battery or attached to it. Once its fuse has been triggered(normally at 2,5v), the battery shows zero voltage & open circuit. Current from a charger should reset the fuse and the battery will charge unless it had been discharged below 1,5v.
Normally devices with 3,7v batteries are shut down by the system at 3,5-3,0 volts, mostly 3,5 like the Note.
Well the device started to flicker and couldn't keep the screen back light on when it go low.... I'd say I have trashed the battery then if it got below 1.5?!
I have left it on charge for over 10 hours a couple of times and achieved nothing
Android shuts down at 3,5v, in case of a freeze(which could go unnoticed if it happens in standby) the circuit at 2,5v. Then it's a matter of self discharge, till the battery reaches the critical point of 1,5v.
The flickering backlight denotes one of the other cables running across the battery, like that for usb.
I think the connections loose by holding the note in your hands, pressing on the backside. A case with a stiff back will stabilize the Note, like mine. Otherwise all pressure goes thru the flimsy back and is applied on the battery, the metallic shields or some spacers. And the cables get bent very slightly during pressure. Should be harmless, but seemingly isn't.
I have done some testing... here it goes:
Battery Voltage disconnected 2.69V
Battery Connected and USB connected 2.8V
Battery not connected or ( after accidently) shorted 1.5V
From my reading android min voltage is about 3v?
Normal voltage from 3.7v to 3.2V and Charging voltage at a max of 4.4V
I also see some talk of 2.7V figure as a minimum cutoff point, this maybe why it will not give 4.4V to charge as below 2.7v maybe considered a write off?
Thanks for your info lecorbusier
With some custom roms, but none i know for the Note, you can modify the shutdown voltage, to squeeze out a couple of minutes battery life, though the voltage goes down rapidly after having reached 3,5v.
