[Q] battery wont charge - Galaxy Tab Q&A, Help & Troubleshooting

i have a galaxy tab and i have the official 2.3.3 update
had no issues until a few days ago
for the last 2 days
my tab wont charge
more than 23 percent?
any fix?

Did you use the charger that came with the Tab or something else? Same thing happened to me after update using other Samsung charger (which worked when in 2.2). Use Tab charger and everything back to normal. Hope the same thing happens to your Tab.

Are you actually only getting 23% battery? Or does that 23% last what would normally be the full length of the battery?
It's easy to think that perhaps you just have a corrupt battery reading, which is easily fixable... with root.

i use the standard samsung charger
also
even when the device is off, it doesnt go past 20ish%
and it lasts for about 2 hours?

I would advise you to the a hard reset, however do your backup before resetting it.
If it doesn't work, probably your battery has encounter issue with the internal sensor of the cpu, I recommend you to send in to the service center to request for a change of battery or do the disconnection of battery by yourself.

if your tab still in warranty time, my suggestion is, bring to samsung service center. use the warranty.

i've rooted the device.

So unroot it and take it back...

[Q] Battery issue

Hey guys. I have one problem with my GT-p1000's battery. The tab was bought in UK in february and it had XXJK5 (November 2010) rom flashed in, also i haven't flashed any other roms yet.
So the problem is:
I use the wall charger to charge my tab and I usually plug it when I go sleep.
By the 19th of may it kept the charge well about 12 hours of intensive usage (web surfing via 3g/listening to music/playing HD games etc.) and I was satisfied enough.
But 3 days ago it started to claim constantly day by day on 47% that the battery is very low (1%) . I tried rebooting it time after time, deleting batterystats.bin file using root explorer, even full drain of battery up until it had no power to start and full cycle charging then, but all these attempts gave no result.
In other words, the battery suddenly drops from 47% to 1%.
I have no idea what to do in this case. Any suggestions?
P.S. Don't suggest me to flash newer rom, because it won't help to solve the problem. A friend of mine had the same problem with his tab and he tried a lot of different roms to flash, but it didn't help. He couldn't find any other solution and he finally sold it.
Sorry mate, i have the same problem. I can't use my Tab longer then 3 hours with very mildly use. From 80% to 3% in a flash, shutdown etc.
I tried lots of roms, resetting/deleting battery stats, touching the screen while turning on the tab, nothing helped.
The only thing i did not try was opening the Tab and remove the battery from the mainboard for a while. Some people say that helped. I could not find the right screwdriver so i just sent it to a repair center. I hope they will find out what's wrong.
Hello,
I had the same problem too, wiping battery stat did not help.
Flashing to Overcome v2.0 rc1 helped some people
but what I did was open up the tab with a tri wing screwdriver and unplugged battery for 30 mins and then plug it back in and it solved the issue.
for instructions, browse this thread:

u may go to the market and install an app called CalibrationBattery , and follow the app wat ask for
if didn't work , update here and maybe i'll give u the other solution
try the easy one 1st

Sudden battery drop down

Hello,
I was wondering if anybody else experiences this behavior:
From time to time the battery of my Galaxy tab drops to 3% (at least this is what Android tells me). I noticed that this often happens when a view change takes place and when I simultanously press the volume control down. Today it also happened on a view change when I was using Skype. When I reboot the device it's showing a normal battery level again (e.g. 43%).
I wonder if this is a hardware issue or if it's a software bug. Anybody experiencing this,too?

Are you rooted/unlocked/rerom'ed at all?
There are various methods to resetting the batteries calibration, but it just depends on what brand you have/what you've done to it.
This is a fairly common problem, and for the most part can be solved easily.
Hello,
no, it hasn't been not rooted yet. Do I need to root it before I can recalibrate the battery?

Ok, there is an app and I need root for it to work. Seems it is solved now.

Which app are you talking about ? I have a very similar problem -- battery suddenly goes from ~30% to 1%, the tab starts screaming that I should connect to the charger, and (sometimes) shuts off. If I then wait 10 minutes, the battery will show again 30%, and it might run for awhile, go to 1%, where it will happily "run" (albeit doing nothing) for *HOURS*.
I'm rooted, have BatteryCalibrator installed and run it (I charged it fully, ran the calibrator, and am waiting for it to completely drain -- so that it wont even turn on, to charge it up again). So I'm wondering if you've really fixed this, and how.
I've contacted Samsung about my problem (the tab is about 6 months old) and they told me to do a full reset (special key sequence in telephone -- dont know if this is different from the "factory data reset" in Settings->Privacy).
I haven't done anything with this rooted phone yet, as it has unlocked everything, and I want to make sure I understand how to go back to a fully unlocked state before attempting to update (running XWJJ7). I also dont want Samsung to update it if I have to return it for warranty service....

[Q] Tab switching itself off

Having a bit of trouble with my tab. It's taken to turning itself off. Usually in the middle of me performing a task. It's happened on while using Facebook, Instant messaging, Picture editing, and browsing the web. (the only trend I've managed to spot is that it only seems to happen while the tab is in use)
Battery is fine, 74%. No warning, just all of a sudden its off.
Its a UK Galaxy Tab, it was running "Overcome_v2.0.0_RC1_Full" as this problem seemed to be persistent I decided to restock and flash to 001003-Overcome_v3.0.1_JUPITER_Wipe. Hoped that would sort the problem, but it's happened twice since yesterday.
Doesnit seem to be the usual shutdown, no animation, no sound, no vibrate. It just dies.
I've tried tapping around to power button and on it (wondering there was some kind of problem with the button but it seems fine)
Has anyone had the same problem? Or better yet a solution?
It's a battery problem. As in physical battery problem. I just had it replaced by Samsung yesterday. Exact same symptoms.

Ahh, not what I was hoping to hear. So the only course is to contact samsung? Is it an expensive thing to have fixed?
This will require restocking before sending it off to them?
The strange thing is that I've never experienced say... putting the tab to sleep, or walking away and leaving it, and having the same issue. It only ever seems to happen while in use.
Thanks for your help mate.
Www.tvc-mall.com sells a lot of tab parts, and replacing the battery is fairly easy, but if you are under a warranty, better to let them do it.
I'm thinking you don't have to revert to stock, because the rom didn't cause the battery - it's a known defect. But it only takes 10 minutes to go to stock.

It'll just get worst. I tested it thoroughly. Went back to froyo, Overcome 1.x (Froyo-based), stock gingerbread, etc. just to rule out software. It was still there.
Well, to be honest, i had the same fear too. Though my unit is still under warranty, and officially, in MY, the warranty for the battery is for six months only according to their website. But when I went to the service center, the replaced it, no questions asked. And judging by their behaviour, seems like it's a known issue.
I just did my usual backups, flashed back to a stock rom, passed it to them, and within an hour, it's back in my hands. Not one cent spent.

Well, if you're sending back to the official service channels, best to get back to stock. Like insurance companies, they'll try to find any excuse to invalidate warranty if they can, so let's not give them any reason to do so.
And it only takes a few minutes.

Ok I've been reading up a bit - before the last resort of having to send my tab back to Samsung- is there any chance re-calibrating the battery could work?
The trouble could be inaccurate measurement of the battery. Tab just dropped from 60% to 1% (pop up warning) in about 20 minutes. I rebooted the tab, and the battery now shows 34%
I do have a terrible habit of not letting my tab fully discharge, before recharging. Infact my tab spends most of it's time plugged into the mains.
I dont think its a battery problem. I have same problem with Overcome Jupiter no wipe edition. Before that(overcme) I was using gingerbread from official italain firmware and there was no problem at all. but now I am having problem. It get stuck while performing task and restart (sometime remains off and I have to restart) . its like everyday now. and yesterday it was off when it was not doing anything. this might create problem for me.
dont know what to do. Overcome Jupiter is great Rom so i dont want to switch to other so may be there might be some solutions.
Any suggestions?

Well, as I've said, mine had the exact same symptoms, which includes random shut-downs, battery suddenly dropping down to low percentages.
So, you can either do these few things which I've already done:
1) Recalibrate your battery, if it still persists after this, then
2) Try going to a stock ROM and see. In my case, I've tested if over the span of one week with the following (Stock Gingerbread, the rock-solid Overcome 1.6.4 (Froyo-based), with battery calibration... with minimal apps.
In my case, it still persisted - thus eliminating software issues. So definitely a battery problem. As I said, I just flashed the stock JPE (since I'm in Malaysia) and just went to the Samsung Service Center. A quick description of the problem... and the staff said they'll change the battery, no questions asked.
@Bikrame... issues with a lithium battery can crop up all of a sudden, especially when it's nearing End Of Life. In theory, a good quality battery should last a few thousand charge cycles, or at least a year depending on usage. However, there's been quite a few reports about the quality of the Tab's battery before hand, so it's up to you. If you think it's a Jupiter/Overcome problem... hey, I leave it to you to decide for yourself.
Now I'm rocking a new battery, 7 months after I bought my Tab, so I'm not complaining, with an 8 hour heavy/continuous usage... on my first charge cycle and now about 30% after a 14-hour mixed usage run on my second charge.
Moral of the story: it's your own call. If you'd like to think it's not a battery issue... ;-)
Well in my case the issue was there a couple of days before installing Jupiter.
I knew I was upgrading so went on a bit of an app install spree, noticed a massive decline in battery use. The random reboots started. Then I upgraded.
Thing is, the battery monitor in the taskbar has always been a bit dodgy... reporting higher than it is. Then a sudden drop. I'm going to recalibrate the battery and see how I get on from there.
Nearest samsung center to me is miles away, and in the UK I cant see them just switching the battery out. This kind of thing usually takes 2 weeks - a month.
thanks for the help though guys
Try removing batterystats.bin or check the governor if your rooted.

I was right; i have Kratos now and problem is solved!

[Q] Galaxy Tab 8.9 random shutdown issues

Hello. Our family has one 8.9 tablet. To upgrade to ICS i had to completely wipe it because KIES did not recognize the device.
After reset to factory settings i was able to upgrade tabled to ICS.
After upgrade we noticed from time to time tablet shuts down by itself. Battery is not the issue because it happens with plently of
battery left. We try to always keep battery above 15% charge so shutdown due to low battery is not the issue.
Once it went down with 86% of battery.
What should i check to find out the cause of these random shutdowns?
I do not want to bring it to the service center because all they do here is to wipe it clean and install new firmware.
I suspect this is not the case.
My wife seems have same issue... with black square on screen... and need very long time to charge @ full...

[Q] Help, please! My battery?!

Okay, so.. I have a Samsung Galaxy Exhibit II 4G.
I have it rooted with the root stock from this thread.
With that said, I've had this phone rooted for several months now. Since January or so. Over the course of that time, the phone has run without fault for months. Recently, I've had issues with my battery draining (as well as charging) far more quickly than it used to. I assumed this was an issue with the battery, because there was a slight bulge in it, so I bought a replacement battery that came yesterday. I charged it full (until the phone said it was 100%), from about 5% charge. It took the normal time (as the phone did when it was new) to charge, of just over 2 hours. It died almost completely about 2 1/2 hours later. Currently, I have my phone charging and it's at right around 90%, after just over an hour of charge from 20%. It used to take far longer to both charge, as well as die. What the Hell is going on?
Just a few notes:
This is not the result of heavy usage (for power drain). I say this because even as the phone was idle while I slept, it died on its own accord sometime throughout the night.
My bluetooth, WiFi, and GPS are almost always off, unless I'm using one of them for some purpose, and I haven't used any of those things since the new battery was installed.
There are no applications running in the background, aside from Facebook. I know this because I'm using Advanced Task Killer to kill everything, and it keeps showing Facebook as if it's opening itself for some reason. This is another issue I'm concerned with, so if anyone knows why or how to remedy this, I'd be appreciative of knowing. Otherwise I'm likely to just delete this unnecessary application.
This is not an issue where the phone is reading an incorrect charge over an extended period. It literally is dying and charging faster than normally.
When the phone is rebooted, whether it be through "Restart" (app from Google Play), via the phone Power key, or removal of the battery, the phone drops around 20% battery life when the restart is complete. The absolute reverse happens (it gains 20%) when restarting with the phone plugged into an AC charger.
Is it possible that this has something to do with the root being outdated, or maybe something updated and I'm unaware? I sincerely have no idea what's going on, as this is the first phone I've ever rooted before. I'm sorry for the long post, but I wanted to give as much information as possible.
It sounds like the battery you bought may be defective. Send it back and get a different one.
Yea sounds like you bought a defective battery. Where did you buy it from? Talk to them and see if they'll send a replacement or get another one from elsewhere
