[Q] Galaxy Tab not recharging

Have my Galaxy Tab for about 1 month, without any problems.
I recently noticed that the Tab is not recharging anymore.
When I plug in the USB charger that came with the Tab, it will very quickly charge to 100% (and I suppose stop charging at that moment)
When I then unplug th device and start using it, I can see it count down the Batterylevel in the Status screen. It counts down the batterylevel from 99% to 15% in a matter of minutes, at which point it tells me to plug in the power cable.
Does anybody have similar experience, or is my tab simply broken?

You should send it back to Samsung for warranty claim. This is very likely a batt failure

Update:
I have done a hard reset of the device and recharged it to 100%.
I was able to use it during several days, in a normal fashion, meaning that I use it during the day, and in the evening let it recharge.
So, the problem seemed to have disappeared. This suggests to me that it must be a software or configuration problem, not hardware related.
However, today I'm again in the same situation again.
I already installed the OS monitor tool to check on active processes and their cpu consumption, but nothing abnormal there :-(
Anybody any suggestions on where to look next to try to figure this out?
thanks

Hi,
I have the same problem. I use my Tab for a month and it always works well until last friday.
In the morning I pull out the chargerplug and after a minute or so the Tab tell's me that I needs to charge and when I putt it on charge after 10 sec's it's fully charge.
So I call samsung support and they told me to bring the Tab to the repaircenter and that's what I want to going to do last friday. But before I bring my Tab I complete hard reset my Tab.
Today tuesday I get a call from the repaircenter that they cannot find any problem what so ever and the battery is hours draining.
They ask if I use a memory card and I say that I was using one (sandisk 16gb) and they ask if I can bring it over so they can test it.
But when I insert the card everything stay's as normal, so I take my Tab at home without a repair and restore my backup with Titanium Backup and I have the same settings as last friday.
This is given me not a fine feeling as I realy tust on my Tab and hope this was a one time only.

I have the same problem....pretty sure it's not the charger too.
Anyone else have this issue?

If you are adventurous, please try this, as I have encountered the same issues previously. By disconnecting and connecting the battery, it somehow reset the battery memory in the processor and everything works fine after that.

Battery issues.
Hi..
I tried the rebooting the phone method by pressing the power on key along with up volume key.
I saw four options and I selected the first one i.e. Reboot. I noticed a triangle with ! inside it and symbol of android. I left the SGT in the same mode for an hr after which nothing happened. I powered off the tab . And when I tried to power on, the tab was not all getting powered on..
I am really worrying what could be the wrong.. !
Please some one help me to bring back my tab to life...

I think that you have to reset your battery stats.It is very simple in clockworkmod recovery (aka CWM). I don't know how to do that on stock rom, but you can search this information.
Regards.

[Q] Galaxy Tab battery drains full to empty in 20 minutes

Yesterday morning I pulled the TAB from the net adapter. Immediately it beeped and turned off. Plugging it back in, the battery indicator went from 0 to 100% in 5 minutes.
Turning it back on, it died in 10-20 minutes.
Turned it back off again, fully loaded it again and played a movie on it, 50% back-light. It lasted for just 20 minutes.
I made a backup to SD, did a factory reset and charged the unit (powered off) to 100%.
Did a restore, and everything worked again.
Battery is still working at 80% after an evening of restoring apps and a night of stand-by.
What the heck happened?

perhaps one of your apps? try installing them a few at a time to see which app is causing it

I also think it's a software problem, after the problem disappeared with the factory reset.
I'm going to check slowly which program is the culprit.
I just can't imagine that a program can stress the TAB so hard it realy drains the battery.
I think it could probably be a misguidance of the android OS from a wrong setting?

I had a similar problem but not nearly as bad as yours. I had my tab unplugged for a while and checked the batter: 30%. So that was fine so I opened up dolphin and INSTANTLY the screen went really dim and said I had less than 3% battery which I did not believe.
Turning the tab off and back on the battery was now at 27%. This only happened that one time and I havent seen it agian. Must be some weird battery level reading bug.....

I have the same situation and also make a backup and factory reset amd later a restore.
That was 2 months ago and until now it works like a charme.

Power off g tab drain the batt
I have my Galaxy Tab for about 3 days ago. Charge to 100% the battery, and then, I decide power off (totally) the Tab. Hold power button, and in the pop-up window, power off the phone!!
After a 1 hour, I saw the screen message with the android icon "POWER RESET or UPLOAD MODE"....and drain totally the battery!!!
What can I do???
See the attached image.......please help me!!

Only 2 things are likely to cause this, the battery being stuffed, or the battery stats database getting corrupted. You could try the "bump charge" method and see if it resets it. (Charge fully while on from AC, unplug, turn it off, charge for an hour or so from AC, unplug, turn it on, turn it off again once booted, charge for another hour or so, unplug, turn it on).
The battery stats can be wiped from the CWM recovery if you wanted to flash that, I'm not sure where the file lives to do it manually.

Hi, just like to share my experience with you guys. I encountered the same problem as mentioned, especially the sudden request to shut down due to battery becoming 3%, although it has 50% left. I tried recharging a few times but the same thing happens, something, it will shut down at 30% battery power level. Then, one afternoon, while I was looking at my pictures (at Gallery), I saw duplication of my photos (3 times) that appeared on my gallery folder. But the key issue is I stored all these pictures (taken by camera or by transfer from PC) in the microSD card (8GB). I tried to do a deletion on the addition pictures (it showed 3, so I tried to delete 2). But to no avail, and the system keep processing even though I tried stopping it. After about 2 minutes, the promot came up, requesting me to do a shut down saying the battery level was low, although I have about 50% battery power left. So, I shut down the tab immediately and removed the microSD card. After that, I switched on the tab and it says 50% power left. But I have to make sure it is possible to utilize the tab until it drains out the battery. Finally, I managed to cross the 20% power level and the tab can still be used .
I was curious about my microSD card, thinking that it may be faulty. I used a pc to open up the content and I discovered the SD card has no problem at all, it didn't have duplication when viewed from the pc. For your information, I have installed "angry bird" onto the 8GB microSD card, I am not sure if it is causing any problem to the tab or draining power from it, because the download (from Goggle market) mentioned something about "preventing phone from sleeping - System tools". I am not sure how this is link to the duplication of the pictures in the gallery folder as well, but I am glad I have found the fault to the draining of the power by the tab.
I would suggest, before anyone proceed with the factory reset, do a check on your storage card or the apps that you have installed in your tab, try to solve the simple way and it can save us a lot of troubles .
I hope it helps............

As knightnz mentions ~ It's the Battery Stats Database being corrupt.
To repair, simply:-
Connect the Tab to it's Charging Cable and ensure the Tab is switched Off.
Next, hold the Power On Button whilst at the same time touch and hold the screen.
You will notice the battery indicator will pop up.
The Tablet will now reboot.
Everything should now return back to normal.
This procedure can also be used for a Tab that refuses to switch on.

Should I do this when the tab is off? or when it is on?
I actually tried both, but I dont see "the battery indicator pop up" as mentioned.

Actually, I missed out an important ingredient ~ The Power Cable.
You need to have the Tab connected to your charging cable as if you were charging the Tab and the Tab switched Off.
Next, hold the Power On Button whilst at the same time touch and hold the screen.
Next you will notice the battery indicator will pop up.
The Tablet will now reboot.
Everything should now return back to normal.
I'll amend my previous instructions to include the Power Cable.

Hi Beards,
Sorry to ask again, is there any way to verify that it has been solved without really draining the power to 0%? Is there any clear indication?
Thanks.

The trick is in holding the screen whilst powering up.... It bypasses the normal start-up routines, resetting any errors that would sometimes require a Factory Reset to correct.
This info was passed on to me by a Samsung representative.

Easy fix, get a replacement, thts bad hardware, shouldn't have a problem exchanging, assuming it was purchased thru an auth retailer. No sense in messing with software and having a headache over it.

Seriously, the press screen thing doesn't work at all. Eventually, I brought it to the service center to do a firmware upgrade and it is back to normal...............
New upgrade:
Baseband version: P1000DXJM2
Kernel version: 2.6.32.9 [email protected]#1
Build number: FROYO.DXJM4
The funny thing is my wife has a unit that was using the same version as mine (old version, we bought them at the same authorised dealer), but she did not encounter such problem. I am just puzzled.

It did not work for me either. Is the charging cable supposed to be plugged in to the power socket or just the cable? (I tried both and neither worked)
I also did a firmware upgrade with Roto JMIv2. And I still see the problem.......Anyone having any suggestions please?

If your GALAXY Tab is running from fully charged to flat in under 20 minutes I wouldn't recommend anything other then... Sending it back to where you go it from?!

It doesnt go flat in 20mins. As a matter of fact, it lasts a couple days with my work load. Its just that when i put it in standby mode let say overnight at 80%, when i turn it on in the morning the battery will be at 50-60%. But when i restart it will go back up to 78-79%.
So im not losing battery capacity here i believe, but its annoying to have inaccurate reading, especially when i am on a trip or sth.

I can understand your predicament, I have those "moments" before. Mine just dies off and need reset to get the battery back. The unknown is always not welcomed to all since we paid so much for them.

[Q] My Note cannot work without charger! Im Panicking!!

I bought a galaxy note GT-N7000 on March 10th, 2012. Today while using the phone, it automatically switched off. I thought "ok fine...just an android glitch" and switched it back on. But as soon as it turned back on and the home screen appeared, not even 3 seconds later, the phone screen flickers for half a second and the phone instantly turns off. This keeps on happening if i turn the phone on again and again as it switches off, but when I connect it to the charger and turn on the power, the phone doesn't turn off. So now, I cannot remove the phone from the power supply and Im freaking out! :crying: Oh and I tried factory resetting the phone twice but it doesnt solve the problem! ANY help would be a life saver! I have not rooted my phone and it runs samsung's stock ICS and I dont even have any launchers. I use my phone as clean and careful as possible; its been 9 months and I still havent removed the laminations on the back panel or the charger, so you can imagine what kind of guy I am! Please HELP ME, im panicking!! Thanx in advance!

First of all stop doing a factory reset on stock ICS kernel as dont know when your phone will get bricked.
It could be a pins contact probelm in the battery compartment. Remove the battery and check if the pins are fine and touching the right places. Clean it ... or the battery just died on you and need a new battery.

1st. Do not factory reset or format anything if you still on stock ICS kernel.. You phone will brick.
2nd. Try new battery or borrow from you friends.

omg! I didnt know that factory resetting on stock ICS can brick your phone!! Thanks for the precious info! I checked the terminals...they look brand new...so does the terminals on the battery (I rarely had the need to open the back panel). I will try another battery and get back to you guys. Thank you so much for your help!

Id bring it back for warrantee if I were you

I am also having same problem, my problem arrived once I flashed my note with 4.1.1 JB ROM.
My note powers off even it is above 90% of battery, if I try to connect 3G data.
If I start it same it powers off after 3-5 seconds on home screen.
If I connect it to charger and start it; it works fine even if I disconnect charger once note starts.
It works normal until I connect again to 3G data ot battery drains below 40 -30 %
After 40% it randomly power off or some time works till full battery drain.
If any one have solution please share.
Thanks in advance

Back from service center. Dead Battery and replaced mother board.
Hey guys, I gave my phone to the service center on 26th and got it back yesterday. They said that they replaced the main board and said that the battery is dead and they had lost 2 screws of the mother board which I found only when I came home and opened the back body by myself (opened cause there was a minute misalignment on the back body). I replaced them with 2 screws from the back body for now and have to take the phone to them again or buy those screws from some electronic shop. They also said that they don't have a Galaxy Note N7000 battery in stock and so did the other service centers here in Chennai, India. I tried searching for it in almost 7 to 8 cellphone shops but surprisingly nobody has stock of it! Can a year old phone's accessories just disappear so fast? I also tried ebay.in but all of them sell it in loose packing with seller warranty which makes me think twice about the genuineness of the product. Any advice as in what direction I must proceed now?

It might be a problem with your battery. My phone gives the problem described above because its battery is completely dead but works fine with a different battery. But my friend who has our same phone has a puffed battery and has the problem that you described. Also his battery drains faster than a normal GT-N7000 battery and sometimes switches off while playing games or doing other tasks that consume more power. Just try to use it with another battery and see if the problem still persists.

guys check the accessory section, there are some batteries suggested as well as vendors if you want new batery.
If warrantee covers it try that first. If like in above example they dont have in stock demand an alternative, especially if its covered by warrantee. You have rights you know.

A couple of days ago I ran into the same issue with my 10 month old note...
Not able to fully boot up phone... After 3 seconds since the power up
It was shutting off.
Battery was showing charge.
Got a new battery... Everything perfect now

Youve got a problem on your battery..you can try that using a new battery that should fix your problem if the problem still there,take your phone to the ssc

Phone dies when it hits 5% battery

So, multiple times now my Note 5 has died within a minute or so of hitting 5% battery. The battery percentage will quickly plummet to 0 and shut down. However, when I plug it in and it shows the charging while the phone is off screen, it shows approx 5% battery. I assume this is a software bug and there isn't anything I can do about it until the next update. Either way, I wanted to see if anyone else is having this issue.

Don't let it get so low anyway. It shortens the battery life.

Yes, thank you. The phone had only ever hit this low a small handful of times.
Regardless, the phone's behavior is not normal. It reminds me of the Galaxy S2 that I had for all of a month in which I was certain was a defective unit. The entire battery would not last more than two hours of use as it would plummet like a rock -- especially in the last 50%. Similar behavior in the note, except --thankfully-- it's only at the last five percent and the battery appears to still have that five percent inside it. The phone just seems to think that it doesn't and shuts down.

Turn off your phone, and then turn it on pressing and holding Volume Up, Home, and Power button at the same time until you see a warning. Then press Volume Up to continue, and navigate using volume keys and select wipe cache/factory reset with the Home button, then reboot.
Please note that by doing this all your data will be lost.

I likely won't restore my phone unless I get super annoyed by this. I'm going to wait until the Marshmallow update to see if this improves with it.
I just watched the phone go from 8 to 1 percent. It wasn't doing anything and I was just staring at it. This was the first time I had ever plugged it in right before it turned off. When I plugged it in, it shot right to 7 percent. I then unplugged it and watched it go back down over a few minutes. This is very odd.

Why do you damage your battery this way? Keep it topped off always as much as possible. Letting it run low shortens it's life. This is a known fact with Lithium Ion batteries.

Sounds like a bug. Easy fix with update
Sent from my LG-H815 using Tapatalk

Did you try just wiping the cache without wiping the whole device? My suggestion is charge it to 100%, unplug charger, wipe cache (While phone is off, press and hold Vol Up + Home + Power buttons, release Power button when you see the initial Samsung Galaxy logo), power down, plug charger back in to make sure it stays 100%, then switch phone on.

People (edit: same person both times ) need to calm down over the fact that I occasionally use my battery to 5%. I mean, really.
Yeah, I imagine it would fix with an update.
Shadow, I'll try that. Thanks.

I knew there HAD to be others experiencing this. Do you have an AT&T model?
I'm currently attempting the battery calibration app route. Most seem to be root only, but I found one that didn't need that. The instructions were to charge to 100%, then use the app to calibrate, discharge fully, then charge to 100%. I'm currently on the last charge -- it discharged over night.
Hopefully this works.

It seems that the battery calibration app has done the trick.

I have this issue as well

XT1097 turning off when the battery is less than 30%

My Moto X 2014 works perfectly, all of its features.
Only one thing is bothering me when the battery is less than 30% cell turns off and when religo it shows that it has more than 20% battery but when it finishes the boot turns off again.
Someone has gone or is going through this problem?
My phone is with the original ROM, unlocked bootloader and custom kernel to be able to root.

I had a similar problem on my XT1096 but the threshold was more like 20%. It would hit between 20%-15% and just turn off. I actually got Motorola to replace it under warranty cause I thought it was a battery problem. My replacement has done it once already. I never figured out what the problem was. A factory reset made it go away for about a month. Then it started happening again pretty regularly. That's when Motorola replaced it.

Thanks for your reply, awaiting more comments/solutions.

Yeah, mine did this @ 12-9% threshold... which really wasn't too bad, but not reliable for general day to day use. You can try calibrating the battery [Google: Calibrate your battery], and seeing if that helps. It didn't for me. Long story short; i went to ebay and bought a broken Moto X 2014 for $30 and i swapped it's battery in my original. I bought many "authentic" batteries on ebay and guess what, they were fakes and never worked. If you chose to go this route, the MOTO X is pretty difficult to open properly without ruining the back. I bought an additional wooden back from China via Ebay. I no longer have this problem, the phone gets to 1-2% before it dies now; which is much more reliable for my use.

My solution is calibrating it with this and I get it to work again. So, is there something physically wrong with my battery and this is just some kind of patch?

I tried this and it actually made it worse. My phone would consistently shut off at around 30% (oh, and I can get MAYBE 5-6 hours out of it before it shuts off, so I can never go anywhere without charging cords, VERY annoying!!), so I tried this. For one, the phone shuts but doesn't restart when I am holding the power button during the BU animation, it just shuts off and no matter how long I hold the power button, it doesn't restart. One of the times I did it, I DID get a green LED shining inside the slot at the top which serves as the earpiece for the phone. That time I had to hold the button a LONG time for it to restart. The end result of all of this is now my phone shuts off at around 40%!

Try downloading ampere app and seeing the health of your battery

This is definitely battery problem my friend...nothing can be done except replace battery ...my entire state doesn't have a good customer care to replace this sh#t battery and now am going to change this stupid phone ..am done charging all the day and sudden turn off s too..
