[Q] Galaxy Nexus shutting down

My GSM Galaxy Nexus has been experiencing random shut-downs, especially when it is in my pocket. I haven't noticed any problem with overheating and I tried rooting it and installing the latest version of ICS 4.0.4 directly from Google's source.
I also have Lightflow installed, but I doubt that it causes shut-downs, since I've only heard of reboot problems.
I suspect it could be a problem with the battery because, whenever this happens, the charge level goes down by at least 5% or more.
So, does anybody know how to remedy this? Or will I have to exchange the phone?

This has happened to me a couple times. I never know how long it's been off. I'll take it out of my pocket, and it's just totally off. I hold the power button and it starts up. Very frustrating bug though... as rare as it may be.
I'm still stock, unrooted 4.0.2 using the extended battery on VZW. Holding out for the first update, then we'll see...

Just so you know next time that happens grab a log and post it. Also, if you battery is down, try wiping stats, that usually brings it back.

Sorry for being such an ignorant and a noob but by log you mean a crash log right? Which is the best way to obtain them?

This happens to me about once a day. I'll come back to the phone and it will just be off. I aslo have root and lightflow installed. What's the best log to get?

It was the battery for me...
This was happening to me too, almost every time I took my phone out of my pocket, it was turned off.
After a couple weeks of troubleshooting and googling, I figured out what it was. It was the phone getting "twisted" in my pocket from sitting and standing. If you twist your phone like your're trying to wring water out of it (not too hard), the battery loosens just enough to cause the phone to lose power. I fixed this by taping a thin piece of foam to the inside of the battery cover to keep the battery in place. Makes the back of phone feel firmer too.

Hello !
I'm experiencing the same kind of power off.
Very often it's in my pocket, but sometimes not.
I've leave the debug mode on for the day, so last time it happens to me i've save a "abd bugreport" to a file.
Is there any clue that can be found in this file to know why the phone shutdown ?
Regards,
Antoine
EDIT : I have YAKJU 4.1 stock ROM, no root, no unlock.

I noticed a while ago before seeing the videos that if I banged my GN against the table a certain way against its bottom left corner that it would shut down. I solved that like the poster above by putting an extra something in between the battery and the cover (paper). That solved lots of the problems I had with my phone shutting down when I put it down on hard surfaces. There is though, I believe, a second software caused issue for some of the shutdowns. I still pick it up once every couple days to find that it's off. I've banged it, tapped it, twisted it, and I can't get it to shut down physically like that anymore.
I'd like to know more about how to pull the logs and find out what's going on.

I've had my Nexus for three days now, and I've had several shutdowns. Two of them were during a phone call, and the other two were during a workout using micoach app. The twisting/pocket option doesn't apply to me, because during the calls I was holding it in my hand, and during the workout it was strapped to my arm. I also have lightflow, and will uninstall to see if there is any difference. Running totally stock unrooted 4.1.1. This is making the phone totally unreliable, and I will return it if I can't get this fixed soon.

Every would have had that problem due to how poorly Samsung constructed the battery slot for the battery to fit it. What I did to fix that problem was take out the battery. Even from time to time rage quit and rip the battery out while the phone was on. And put it in, and push it a bit up toward the camera. That fixed my battery issues. Others have put a foam thing (sorry I don't know the name) where the battery slot golden things were so the battery wouldn't move. You can also try that.
Galaxy Nexus-codenameandroid rom

I uninstalled Lightflow after posting my previous message, and since then have not had any random shutdowns. All calls are performed flawlessly, and I've used micoach several times again (this was when the problem was most obvious) without any problem. I haven't changed anything else, so I'm pointing my finger at Lightflow. I'm installing it again to make sure it was the cause, will report back.
Regarding the battery problem, I've been looking at it and can't see how it can become loose. It is really tight, and there is no spare room to add any kind foam. Maybe thye have tweaked the design on later batches? My GN was built March 2012.

I had the same issue and it was caused by an app. The app "Boid", a twitter client still in beta, was causing the reboots. The reboots occurred once or twice a week, they happened on 100% stock ICS, 100% stock JB, custom roms also.

Like the above poster, I uninstalled LightFlow and am no longer having any issues. I'll try and get in touch with the developer and see if there are any logs I can get to help.

[SOLVED] NOTE 10.1 2014 edition - fake battery percentage / battery drain issue

hi guys,
I have learnt a lot from xda and had been using this site for all of my android issues and mods. This is just fabulous.
So, I have been using my Note 1 0.1 since a couple of weeks and it's battery was acting in a funny manner.
PROBLEM
Sometimes it played well down to 60% from a full charge , then down to 15% in a minute and then down to 4% in next 5 minutes. Then i would restart the tablet and watch the battery suddenly having around 35% battery. THIS WAS SO WEIRD.
I used many battery calibrators from play store but none of them worked.
SOLUTION
And then out of frustration, I pulled out the back cover, took out the battery connector, and then placed it firmly, back to its place. switched it on used it for couple of minutes, and noticed the battery percentage. restarted, YAYY! same battery percentage. used it again, restarted, checked again. did it more often and noticed that the issue was solved.
CONCLUSION
The connector of the battery on the main board gets loosen up with time (maybe) and there is interruption of current transfer.
therefore the battery gets it's funny character.
HOPE I SOLVED YOUR PROBLEM, CHEERS!

Hi,
i have the same issue...
is there anybody tried this and can confirm this solution?
I also will try it.

More information
I tried to do what you suggest, I opened the tablet and found this:
can you please explain what to remove and how? Thank you

Lift the tape where the two back ribbons connect, release the clamps, remove the ribbons and reinsert them firmly and replace clamps and tape. That is what i did. Been having this problem for months! Will report back when i drop below 50. That is when all my problems start. Really hope this works!! Thanks for the help!
Update: I am sad to report that I am still experiencing the same problem.

I think this is wrong. In my suggestion the power connector is the white one in the middle with the red and green cables. Just remove the tape and lift the connector upwards to you.
I think the other two black ribbons are for the USB port and for the mic or so.
It worked for now. The battery consuming is extremely better then before.
I hope this solved the issue.
merry Christmas to all

I apologize i left that part out but yes i did that as well. I would like to see others people's results as well though.

Or is it a rogue app?
I've been having the same, infuriating issue, including the CPU getting really hot.
I reflashed ROMs over and over, with and without formatting data, I went back to stock, flashed different kernels...OMG, the amount of time I have wasted is frightening.
I'm finally trying the following and it seems to be working:
- full wipe, reflashed Hyperdrive 4.1, as per his instructions
- on boot, waited 10 minutes and rebooted.
- after reboot I didn't allow ANY automatic updating and I started reinstalling apps one by one.
- battery life has been stable!
- And now I may be on to something! Yesterday, after updating the following 10 apps, the same crazy battery performance reappeared. Then when I uninstalled the updates to these 10, the battery life returned to normal and not acting crazy:
- Dropbox
- ES File Explorer File Manager
- Gmail
- Google
- Google Keyboard
- Google Text-to-Speech
- Google+
- Maps
- Papergarden (Tab S)
-Samsung Link
I'm going to one-by-one see which one induces the crazy battery performance.
Watch this space...
UPDATE: I think it's Samsung Link...when I updated it, the same f****ed-up battery behavior came back! I think I found it! Woo-hoo! Woo-hooo!

I`m having this issue too, got bored changing roms and kernels, KK or LP still no result.
Battery drains much faster on gaming like Dead Trigger 2. 100% to 20% less then in one hour. If browsing and watching videos or doing other stuff SOT is nearly 4-5 h. Besides, when boot into recovery, battery percentage always differs from ROM one and never matches to it. Didn`t try yet method in OP, but anyway, I`m interested in this NewPower99 Battery replacement kit. Did anyone test it?

I would be interested, but since we have three months lefts until Mobile World Conference in March and we could see the Note 10.1 2015 or Note pro alongside GALAXY S6.

Solution
I take the tablet to the samsung and the problem is the board, they had to change this part.

Thanks dude, that really helped me. I got rid of the the fake percentage and I have the feeling that my battery improved . Thank you again

[q] *extreme battery drain?*

Peace...
Recently purchased a SS3 Steel from eBay, new out of the box with seal around package. Upon setting it up, I immediately updated it to LolliPop. I synced my apps to my watch (which include the basics like, Wear Launcher, WatchMaker, Facer and etc.). At first I didn,t notice the battery drain, as I was just having fun playing with it. But after a hour or so I was down to 40%--->and I just attributed it to battery having to cycle a couple of times. Here it is day 2 with watch and i have to re-charge it every 4-5 hrs---> this cant be normal.
Is this something to do w/ the recent Android Wear app update? Is there anything I can do to fix this battery drain---or do I have a defective unit?
Suggestions please

Hi, I've had my sm3 about 4 days now and the first couple of days was forever charging the watch. I eventually found the culprit was that I had location switched on in the watch and phone settings. After I disabled it I'm getting easy two days between charges. Location is handy for running or out on the bike but otherwise in day to day use not really needed.

T700 becoming unstable when battery lowers

Hi,
I've a strange behavior from my T700 that I was initially thinking due to the 5.0.2 but I'm no longer sure about that.
The problem is about the home screen that often freezes or make some stripes on the screen.
Since it appeared only after the Lollipop update, I thought it was due to the infamous problem of memory corruption in the 5.0.2.
Sometime it is so horrible that I'm obliged to reboot several times the tablet that anyway remains unstable.
Digging deeper, I'm observing the instability is tied to the level of the battery gauge... the lower, the worse. If I plug the charger, I get a stable reboot.
After Lollipop the system looks having gained battery lifetime, but in reality calibration looks having changed and the tablet became unstable when gauge is below 40% (well, it is difficult to say because sometime the gauge remains blocked around 50-55%, and moves to <10% only after a couple of reboots).
Question: is it happening only to me (in which case I may assume my tablet is defective so I have to sent it back for repair in warranty), or a common behavior with this very bad update (in which case I may consider to switch back to Kitkat)?
Thanks

Just go to service center and claim a warranty for new battery replacement.
Its the infamous batterygate of Tab S. The longer you wait, the worse it gets.
I just get battery replacement yday and the Tab S is working like new, mine is T705 with KitKat.
It only took about 30mins to replace the battery.
And I got the same issue as you before. No software fix can rectify the problem.

I had the exact same problem. It's not sofware related. I opened my tab, disconnected the battery and connected it again and the problem disappeared. And re-appeared a few month later. I did tje same trick and it worked again. In my opinion, the faulty one is the battery connector, not the battery itself..
Plus: the best tool to open your tab is a guitar pick..

Having same problem over here with my Tab S 8.7 (T700).. At about 60% my screen starts to flicker once a while. Was planning on a factory reset and otherwise going to the service center as it is still warranty.

I had not yet time to go to service (they said they need to investigate, I'm afraid service will take several weeks, not just 30min).
In the meantime, I'm realizing that tablet in power saving mode has no problems at all... A good workaround while waiting before servicing it.

For what it's worth, a friend was having the exact same problem and we were both sure he would have to at least open it up and check the battery connection. However, he did a factory reset (he was still on stock 5.0.2) and the flickering/flashing/freezing problems disappeared...for what it's worth.
TiTiB (tweak it 'til it breaks)...Galaxy Tab S | SMT-T700 | klimtwifi...AICP 5.1.1

It may be not software related but! With a few tweaks it seems to stabilize again... A couple drops with the cover, then lollipop update and it was it, problems started... Removed the cover seems to help, then custom rom, skyhigh kernel and some power tweaks here and there, 14% right now with 6:30 to 7 hours screen on! No errors so far!

Service will reset the device before any intervention, so better I do it myself and check if problem is still there.
The problem appeared only after the Lollipop update and although may be totally uncorrected (once, it happened to me a S3 battery almost exploded just after an os update, what a chance!) it is worth a try (there are also some other strange effects that looks more related to memory corruption, although those may be caused by abnormal battery levels).
I'll keep you posted

HELP- Roms keep crashing on Tab Pro 8.4

let me start off by saying ive worked on two galaxy Tab pro 8.4's, one is mine one is my dads. my tablet has no issues, his however crashes after a little while of being on ANY Rom. we have tried Cyanogenmod, Slim Rom, and Resurrection Remix, all of which i have installed on my tablet without any issues but after a while on any of them it just goes into a bootloop. This is what i do every time I install a new rom-(1) Boot into TWRP (2) Wipe everything except SD card (3) Flash Rom and appropriate Gapps. am i missing a step? am i doing anything wrong? At first it looks like it is working then after a week or so it just goes into a boot loop. I am confused because i don't so anything different on my tablet. any help is much appreciated.

Try using one of the debloated stock roms

Sounds to me like it might be a Battery / Battery connection problem. Especially if the Device just suddenly dies - reboots like that.
In my experience random reboots just happen. Perhaps once every few weeks or so? But I hardly if ever actually turn my T325 off.
I dare say the only time it ever gets to that state is if the Battery has reached that level of depletion.
*Edit* So probably 'cause of that, and having amassed a lod of crap in that time, and so just the one random reboot happens.
But, I can recall having replaced the Motherboard in my Device, which I placed into a replacement house, after trashing the Display on my first one. Which had such random boots, when otherwise held normally. Eventually reseating the Battery Connector managed to fix it for me. Like I said Random reboots are a thing, and they will happen, in my experience even on stock Firmwares. Especially if you never really ever do a manual reboot from time, to time.
But, such sensitive crashing, rebooting, caused by just looking at it funny is not normal, and IME is likely down to either a bad Battery, or more likely a poorly connected one.

Thank you, i will look into this. Its a definite possibility.

Did re-seating the battery work for you? I have a Tab Pro 8.4 that has been doing a lot of random reboots lately -- I also have tried a lot of ROMs (including the three you mentioned) and things only seem to have gotten worse, which is why I suspect a hardware issue. I'm typically at one reboot every 10-15 mins of use. Any suggestions welcome.

reseating
reseating the battery does wonders, it stopped the bootloop for me and increased the battery life as well, you just need to be cautious when u reseat it
