[Q] Galaxy Tab 8.9 random shutdown issues - Galaxy Tab 8.9 General

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] 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.

[Q] battery wont charge

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.
Sent from my GT-P1000 using XDA App
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] Galaxy Note GT N7000 Battery Drain and Screen Flickering issues

Hi Guys,
I have bought my Galaxy note GT N7000 more than an year ago. I still consider myself as a newbie to android and I still have Gingerbread 2.3.6 on my GT N7000.
Everything was working fine until recently the battery was draining a bit more quickly than usual. Charging to 100% is also very fast taking only 45-60 mins. Normally it would take 2-3 hours previously. I observed this odd phenomenon only a month ago. It was the time when I download many GO Locker themes free using GETJAR. Please note that I downloaded many apps that GETJAR asked me download and I downloaded apps only from Playstore. It was also during this period that I put a Transcend Micro SDHC 16GB class 4 card into my GT N7000. I also have tried removing many apps that got via GETJAR but still the battery drain issue is present
Today I was hearing music and playing temple run, When the battery levels goes below 30%, the screen begins to flicker. However I ignored this and continued playing and the flickering frequency was increased and there was constant flickering when the charge was around 15% and finally when the charge was around 11% the phone was powered off automatically. Even I tried to power on, it would not come and then I have to remove the battery for a few min and placed it back and powered the device and only then it was powered on.
I'd appreciate, if anyone could let me know how to troubleshoot these issues. Please note that I don't want to factory reset my GT N7000 as I want to retain all my apps as well as Games data without rooting.

K.Ramesh Karthik.

+Whiskeyjack4855 - Thanks for the reply. Are you sure about it? Because one of colleagues told me that it could be due to a huge number of app that I have installed on my phablet. Will the battery die within 2 years as I bought my phablet on Dec 2011?
Regards,

Lot of issues on battery has bee reported after one year of usage.
Mine died after 14 months, the battery began to swell and during usage i think it heats up and comes away from the contacts.
A new battery completely fixed my problems so it should do for you too. Buy an official sammy one, it was only £8 in uk from amazon. Well worth it
same issue

Same problem after updating to JB official ROM
Hi,
I have the same problem after updating to JB official ROM. After the screen flickers, the phone turns off, and when I turn it on again, the battery level drops insanely. If turn on again, I have another battery level, until screen starts flickering again. This happens over and over again...
Once I plug it in, it starts behaving "normally" and after 2 or 3 hours, it starts this crazy cycle again.
This didn't happen before the update.
Any ideas?

This exact thing happened to me just recently (Note is from original release batch, so nearly 18-month-old battery) - replaced the battery with an official Samsung one off of Amazon UK and it stopped. Make sure you get one from a decent supplier, or the "fulfilled by Amazon" one: first time I got a dud battery that wouldn't even turn on.
My battery was bulging - it doesn't fit in the gap properly and the back cover has a bit of play that was never there before.
same here..
only yesterday...new battery..2 months old?
It happened with me even with ics, my phone came pre installed with. But flickering only happens when my battery reaches 1 percent. Usually 2-3 mins after it reaches 1 percent. And then soon the phone turns off. Basically it happens just a few seconds to a minute when the phone is about to turn off. Otherwise it doesn't happen. This is my 4th note. It never happened on my previous 3. Hope that helps.

I'm having this same issue now... I've ordered a new battery from Amazon.... hope it solves the problem
If the battery drains like hell, and it's bulging, get a new battery. It solves the problem. I had this problem last week, and new battery got rid of it.
Me and my wife bought our notes at the sane time but her battery lasted a few months longer than mine did.
Seems like a new battery after a year or so it's inevitable.

Same here, my battery is 16 months old (now having a bulge too). Screen flickers @lower battery levels pretty much every time, though never when phone is connected to charger.
It seems Samsung Battery Life is less than Nokia
same issue exactly appeared after 17 months of buying.
I was charging the mobile via Car Charger which reduced the battery life.
after buying a new one, it worked OK but to be in safe side I upgraded OS to ICS.
It seems Samsung Battery Life is less than Nokia !!!!
The same problem
Actually i do have the same problem 5 days ago,mine is 15 months old Galaxy Note holding Jellybean 4.1.2 XXLT5 ofw . I asked help from specialist in mobile phones and he told me to change the battery immediately , so i asked for the battery (Original one from Samsung retailer) and it will be delivered for me this Monday. I'll keep you informed by details.
---------- Post added at 05:07 PM ---------- Previous post was at 05:03 PM ----------
I noticed also the flickering is accompanied by heat in the device processor , at the end of the discharging process (20 % 10% battery signal) or while surfing the 3G for longer time . sometimes it shut down suddenly

[Q] Weird battery issue, Razr i, after Jelly Bean

Hi all,
I have weird battery issue with my Razr i xt890 and I'd like some help. I have tried googling for information, but there's too much noise and I can't find anything suitable.
I'm asking on this site because I know the people on here are really knowledgeable.
My Razr i (with Jelly Bean) seems to have erratic battery readings. Sometimes it'll drop to 6%, and then go up to 90%, and jump around to points in between. I have even seen it drop to 1% and then go up to 6% (or something like that).
Needless to say, this makes the phone unusable because I don't know when it's on low battery so I can charge it. Furthermore, twice, it has reported low battery and then automatically shut itself down.
I hope someone can help with this, because I'm really stuck. I bought this phone overseas, and I don't really want to send it back overseas for warranty repairs.
So, some history.
Before the issue:
This is a stock Razr i, running Retail GB software. When I bought it, it was running 81.5.31002.Retail.en.GB 4.0.4. I upgraded to 81.5.39001.Retail.en.GB 4.0.4 and it's been running fine until this issue happened. I normally get about 4.5-5.5 days of battery before I recharge the phone.
This is stock software. No root. No bootloader unlock. No custom roms.
The issue:
I charged up my phone yesterday, and unplugged it from the charger at 100% battery. There was a notification that 91.2.29001.Retail.en.GB 4.1.2 was available. I selected 'Later' because I was busy at the time.
A bit later (maybe about an hour?), I went back to the phone and checked for updates, and selected to download the update. After it was downloaded, I noticed the battery was about 95%, and then I proceeded to install.
I figured 95% power should be sufficient to perform an upgrade.
The install took, maybe 10-15 minutes? At first glance, it seemed successful, but when the phone started up again, the battery reading was at 100%.
I distinctly remember thinking 'This is impossible. There's no way it could be 95% before the install, and 100% afterwards'.
I played around with the phone a bit (to try out Jelly Bean), and after a few minutes, the battery reading dropped to 60% or something.
That's when I knew something was wrong.
Since then, the phone battery reading has been erratic. If I plug it into a charger, it takes a few minutes and then shoots up to 100%. Unplug it, and it drops to a low level within minutes, and then goes up and down like a yo-yo. Twice, the phone went to a very low level, and then shut itself off.
I've tried various charging/unplugging cycles, and nothing has worked yet (Although I didn't have the patience to try an 8-hour charging cycle yet).
Please see the attached images to see what I mean.
The graphs are just bizarre.
I also did a factory reset (from the Privacy menu rather than 'recovery') but that didn't help.
At the moment, I haven't tried to root the phone or unlock the bootloader. I am still keeping the option of warranty open.
I can't think of a reason why this is happening. It doesn't seem to be a simple calibration or battery stats issue. I think the battery is working okay (because it was fine before the upgrade), just that the readings are wrong.
The phone is operating okay in all other respects. If I ignore the battery readings and the 'low battery' alerts, the phone continues to work ... except when it shuts itself down.
Another theory could be that ... because I upgraded without plugging the phone in, perhaps there was insufficient power during the upgrade and caused some corruption, and I have a faulty software/firmware? Not sure how I could test that though.
Any ideas, any one? Please?

Jelly bean download issues
Hi, I have had exactly the same problem after downloading jelly bean. It even died when plugged in charging. As I had only had the phone for three weeks, I took it back to the shop, Phones 4 You, and they exchanged it for a new phone and told me not to download jelly bean until they let me know it's safe to do so. They said that it was a software problem. Prior to this the battery life was outstanding and I am very pleased with the phone. Phones 4 You gave me an excellent service.
Fixed!
For future readers ...
Someone on the motorola forums (see second reply on this thread) mentioned a possible solution which was to manually install the Jelly Bean version again. I decided to give this a try.
After some more research, I discovered that it should be possible to manually apply official Motorola (ie. OTA) updates using the stock bootloader (via the bootloader recovery feature). No unlocking, no root needed.
I gave this a try ... downloaded the software (keeping to the same version), placed it on an SD card, went to recovery and selected 'Updated from external card' (or something like that) and followed through ... and it has worked (Although this time I kept the phone connected to a usb cable throughout the upgrade). My battery readings are back to normal again. I didn't lose any data or apps as a result of this 'manual upgrade'.
And I am presumably still under warranty since I didn't root nor unlock the bootloader.
Other readers may consider trying this for themselves, however, I cannot guarantee that it will work for them. I can only say it worked for me.

I don't have the phone yet (supposed to get it tonight) but having read quite a bit it seems Moto suggests a factory reset after upgrading to JB in order to sort out battery drain etc. I think I saw it in the battery stats thread in RAZR i general.
I send my Razr I back to Germany (living in The Netherlands myself) yesterday! Had the same problem, only my battery get down to 0% all the time, so the phone shutsdown itself every 1 minute till 1 houre. (I'm from the topic: Auto shutdown (battery problem). I think i get my new one next week on wednesday. Dus the JB software manualy update works for more people?

I think the problems described in this thread are relating to strange battery spikes in percentage and not a general drain of battery.
The problem is that everyone seems to be different. Some people report these spikes, some people are reporting high drains (which turning off google now or factory reset seem to fix) and some people (luckily me!) have had no issues at all - just an even faster phone
I did do a factory reset, though not immediately after the first JB upgrade. It didn't help.
I think describing this issue as battery drain or high battery usage is not quite correct. The battery is actually okay*, but the phone's indication of the battery capacity jumps all over the place (and sometimes causing automatic shutdown). I can see how it can be confused with battery drain though, especially if people only observe the reading going down (but didn't see the reading going up).
* At one point, I kept the phone screen on as an attempt to drain the battery. I got about 6 hours screen time (ignoring the intermittent battery low warnings) before I gave up.
Since I now have a phone with JB which is working, my guess is that this bug may not occur in all phones with JB. Instead, it seems to be triggered by something that happens during an upgrade.

i have the same problem. factory reset did not help me and i feel i made a mistake i have choosen this phone.i had motorola mobiles before even bought one to my wife.i know that motorola has a conservative atittude.i thought giving them a last chance now i know it was a mistake
Thanks bengtan.
I was having similar issues and a manual install of JB appears to have solved the issue.
Have you had any luck fixing your phone? I have the same problem since a few weeks ago. Bought a new battery and tried two calibration programs, but the issue persists.
Same here. I am on KK 4.4.2 and have the problem since yesterday. What to do?
Same here, my ROM is cm-11-20160524. After 3 years of usage I thought it's the battery and replaced it with a new one but the issue persists.
This is very odd, I'm here after my dad has the same issue and it looks like I'm the 4th poster to report the issue within 50 days after the thread hadn't any replies for over 3 years! Did any of you recent posters resolve the issue? I had a spare Razr-i and my dad took it to a phone repair shop where they swapped both batteries and the issue was still the same with the other battery, so it seems it's nothing to do with the battery itself for all the posters here so far.
Was there some recent update that spiralled all the phones into the erratic behaviour recently I wonder?
I'm trying to advise my dad what to do:
Try fix the issue on his current phone and keep using relatively old tech phone
Use my spare phone (same type) and keep using relatively old tech phone and try sell old XT890 for parts
Upgrade to brand new phone with latest tech and do him for a few years longer than the XT890 would.
Any feedback appreciated!
The issue flatened a bit now. After 2 weeks of brave usage the phone keeps the charge now normally with rare drops in between. So it's still not on an acceptable level but improved magically. I do not understand the physics of this behavior.
I'm having the same strange behaviour since yesterday!!
battery level drops when pluggin the charger,
after several minutes level is jumping to 100%.
whith unplugged charger, level in general inconsistent jumping up and down...!
could this be SW related? planned obsolescence?
edit: android 4.4.2. systemversion 990.43.74.XT890.Retail.en.EU

I'm now looking for a copy of the new firmware: 990.43.74.XT890.Retail.en.EU to try to resolve. If anyone knows where it can be found I'd be very grateful if you could point me in the right direction...
Same problem here.
I bought a new battery. No changes.
I than did a complete wipe, unlocked the bootloader and installed CyanogenMod 11 (this one http://forum.xda-developers.com/razr-i/development/rom-unofficial-cyanogenmod-11-t2966855). No changes.
I than completely drained the battery (made sure of it) and left it on the charger over night. Now I don't get those weird spikes, the battery just drains really fast (about an hour an the phone is powering off).
Maybe I try a different ROM, or go back to KitKat
I found this but I dunno how to use it ??
