[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.
Sent from my Overcome-Powered Tab!

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.

Android OS staying awake 6 hours +

I am stock. Not rooted.
I have restored the phone to factory settings thinking it will help it. But it hasn't.
I have tried the completely stock and immediately the Android os was keeping phone awake. Then I started disabling Verizon apps, unnecessary g9ogle apps and still I have the os keeping phone awake about 6-7 hours per charge.
What should I do? I've dealt with this on my old nexus 4 and haven't been able to figure out why Android phones are plaged with this Android os wakelock.
I believe this all started when I got the 25b ota. After that I've done a factory restore. I don't have Verizon so I'm not getting any more ota for 26A. Is there a way I can manually flash the newer rom?

No answer for you, but just wanted you to know my battery life with the last 4.4 upgrade just the other day is now miserable. Can not make it a day. Use to be able to get like 2 days. Thinking about just selling the phone, and buying something new cause of it.

Have it installed.. even installed greenify yesterday to see if that helps.. Wiped some of one of the batteries average length per charge and started it fresh today, so I am going to chase it down I hope. Battery shows it's Android. Note 4 anyone? Have to pay full price for it though, can't justify 700 bucks. But I do have a trip coming up where I have to be gone for 2 weeks.. so maybe then?

Let it sit for about 30 mins with the screen off untouched, see if it's going into deep sleep, report back your findings under partial and kernel wakelocks also.

See if this is what you meant...if not a nudge into the place to look would help me..

Looking at the second set of shots, are you on a public/work wifi network? The wlan wakes are what's keeping your phone from sleeping. That can be caused by things like DHCP queries from the network waking it up, etc.. My battery life takes a hit when I use our open network at work, constantly woken up by the wireless lan.
Are you having the same issues off wifi?

Yeah, I normally don't run wifi. I just happened to turn it on today at work. I can let it sit for another 30 mins or so and do the same thing. Phone is at 57% screen on time of 1 hour, I use to get at least 4-5 a while back.

Add me to the list.. I'm stock and after the update a few weeks ago this turd heats up lots, freezes, re-draws home screens VERY slowly, Swype effs up badly now and my battery life is literally about cut in half. This is all after a factory reset after taking the update.

...as I said, I'm stock. My wife has the same phone and hers has no problem, or so she claims. However, her phone is nothing more than a window into the world of Pintrest and Facebook whereas I actually use my device constructively.

I just took the plunge, flashed back to 24a, re rooted, upgrade to 26a, and now it is much better.
Tried to post a pic.. but it is too annoying
26h 20min battery usage,
@24%
screen on time of 3hours.
That is much more in line in what I got when it was new.

So just running it all the way down, 33.5hours of usage @ 5% battery left, 3.5 hours of screen on time.
Much better.
I'll try to grab the battery pics, since I know no one will believe it..
You might want to fresh flash.. not sure what got messed up.. or if it was an app. Even though it was listed as Android system stuff.

Battery issues are killing this phone for me

So, I really love this phone. Despite not being able to get it sim unlocked yet, I find that I'm even more satisfied with it than I expected. There's just one glaring issue: Battery drain, specifically at idle.
I have tried everything: Uninstalled/disabled all apps that I didn't need, used App Opps to turn off "keep awake" for just about everything that I could. Nothing works. Last night, I left it off the charger with 100% and 8 hours later, it was down to 50%. It loses 5-7%/hr at idle without doing anything at all. I'm in a high signal area. I tried charging it to full and turning off wifi. That had no effect either.
I'm seriously torn between wanting to return it because I can't even get through a single day on a charge and really wanting to keep it because the camera and screen are so awesome. I'm sure there will be an update down the road that will fix this and I don't think my device is defective. This drain definitely isn't normal.

Do a hard reset and see if that works.
If not take it in to tmobile, do a hard reset there And let it sit for 20 minutes and show them the idle battery drain.

I'm not wiping my brand new phone that has been doing this since I pulled it out of the box. A hard reset is not the answer to everything. There's definitely something wrong with the the software build.
It's my fault, of course. I should have added "in b4 do a hard reset" at the end of my post.

I know it sucks but try and tough it out. There is a massive issue relating to WiFi on this device right now. I am doing some testing but I think proof can be found in that when you turn off WiFi but WiFi calling was enabled in the dropdown you will fail to get cellular signal back at all. It will stay "Searching" all the time.

Yeah, I have tried leaving Wifi off completely, but I'm still draining pretty fast. The problem is, the phone is almost unusable for me like this because I can't even make it to the end of the day if I use it at all. And since I rooted, any update they release is going to be a pain to apply.
I blame 5.01, to be honest. The best thing Samsung could do is rush out a 5.1 update.

Same thing was happening to my phone out of the box as well, something was keeping it from deepsleep, did a hard reset, put all the same apps on. Now it sleeps like a baby.
I should note that battery life still isn't great but it does last me through a whole day, still getting high cell stand by drain.

Glad to hear the factory reset seems to be working. Let's work together to try to narrow this down and not result to attacking each other

From the Moderator
OK People, Cleaned this chaos and trolling.......
Post respectfully or ........DO NOT POST........... easy
To your battery issues......... these issues are pretty much the same with all phones, so the fixes are pretty much the same\
Hard rest
Go into the menu and disable apps that are pinging GPS
Freeze apps that you do not need -if you are rooted then use titanium back up to freeze or other app that does the same - if you are rooted I would disable any updates from the Carrier or Samsung- that means disabling the patches/apps that control those.
Turn off WiFi and Bluetooth when not using it
Avoid leaving social media apps running in the background they can be battery hogs.......
This is what was recommended in 2010 ........... still pretty much good advice ........
The next person that posts disrespectfully or trolls will be met with an infraction
Keep kind and civil and ON TOPIC ONLY
Thanks ~~~ oka1

I have had zero problems with this phone's battery, but then again I always factory reset after an update. Got the 177MB update, installed, FDR, and butter ever since.
I get about 6 hours SOT with heavy use.

Dude, I was having the same exact problem with my S6. First, I disabled all of the apps I wasn't using. Next, I turned off wifi-calling. After that, I turned of VOLTE in the phone app. Last I backed up my music, pics, contacts, and sms's, and done a hard reset. I restored my stuff and completely charged it up. Now I am only loosing about 1% or less an hour at idle. I charged it up at 12, left it sitting and 3.5 hours later it's on 97%. That is quite an improvement for me as my S6 would be below 50% in the morning if I left it off of the charger over night for 6 or 7 hours......Just my two-cents to try and help. Good luck bro...

I wanted to add that this didn't start happening to me until after the OTA was installed, before that, it was good to go for a whole day so the OTA does something to knock things off track.

How do you do factory reset? When I go into settings-backup and reset, hit reset- it gives me the warning and I proceed then the phone just shuts down, and nothing happens.
Method 2 - I power off, then hold vol up, home and power, until this logo comes up and then it goes black. I am strating to think that there is something wrong with my stock recovery.
thoughts?

Did you try to root at some point?

Haven't several people said that the Cell Standby issue only started to appear after the update? I would wait on the update a bit to see if you have any battery issues just for the sake of knowing. Then update and see if it makes a difference.

It's not the update. The problem is VoLTE and WiFi calling. Turn those off and it goes away. I'm on the update and have no high cell drain since doing that.

5.1.1 Battery Drain

Is anyone else having huge issues with battery drain after updating to 5.1.1. I've disabled all the crap, wiped my cache, disabled enhanced LTE. and have minimal apps installed besides stock. Just took the phone off the battery charger. It was at 100% when removed. It's been sitting for 40 min with the screen off. The battery is down to 93% already with 3% being used by Android system, 1% by system UI, and 1% by Android OS. This is nuts. I can't even get through 1/2 a day of regular use. Any ideas?

Big time. My phone isn't going to sleep. My Android System Stay Awake time is more than double my screen on time.

I'm having the same problem. I currently have Location History turned on to get more surveys on Google Opinion Rewards (I could turn that off if I wanted to); and I also know that because I'm not in WiFi during the day, the Lollipop mobile radio active bug keeps the radio awake way longer than it should. It's crazy that I can leave my phone alone during the day and watch it drop ~5% an hour because of the horrible standby behavior.

There is something wrong with your phone or app. I have about 100 apps. No problem here.

I guess it might make sense to stay on 5.0.2 in hopes of a future bootloader unlock and to stay away from a potential battery draining bug. If only AT&T would embrace a more open approach to this model phone. I only got this phone because the nexus was out of stock and I was in need of a new phone. My trusty old S3 was a godsend, with its unlocked bootloader and fully open platform. The fact that AT&T is closing up the ability to root the phone is drastic enough, let alone introducing bugs that make you want to throw the phone at the wall (battery drain).

How can I see what is keeping my phone awake without root? It's staying awake 3/4 of the time and below is a shot of my app usage. What I can tell it's a system issue, but not sure. And yes I factory reset twice and wiped cache.

Same here. factory reset cache wipe x2 and have everything non essential disabled. It's driving me nuts! This phone was a rockstar until this update. Going to best buy tomorrow and will see if the Samsung folks can reinstall the update or something. I'll post what I find out.

Battery life is worse than my old s4. The screen barely takes any of it, when it used to be more than half the battery life on my s4. Yet I still get about the same screen on time.

Yup I completely agree. Left my phone at 53% overnight and I woke up to the phone completely drained and dead. It's ridiculous.

I noticed something odd. On wifi, battery life is great, maybe 1% every 2 hours idle. But without wifi, battery life goes down 10% an hour idle.

Finally made it to the Samsung center at best buy. The guy was able to force the update again and everything went smooth. So far maybe a little better, not sure yet. I'll post when I know for sure if it worked and was a bad update.

So after the forced re-do of the update it wasn't any better. List 20% at night with everything off. Dido another factory reset and cache wipe and that seems like it might have fixed it. Only 4% list last. Not as good as it was but definite improvement. Hope this helps anyone else with same issue.

TurboRZR please update... would love to know if that fixed it before I wipe my S6 for a second time.

I too am having an issue with the new 5.1.1 update where my "Android System" is getting stuck in a stay awake loop draining my battery. Sometimes a simple restart will fix it for a few hours, but it will always come back.
I installed wakelock detector and set it up to run on a non-rooted phone. When I pulled the statistics , the biggest battery drain I had under "Android System" was diagnostic.client.network. Nothing else even came close to the drain this resource was pulling.
This was as far as I was able to get as I have no idea what that is or how to disable it if I even should.

I have resolved the issue on my S6 Edge, I even attempted a factory reset which didn't resolve the issue. I had noticed my Wifi usage in GSAM was very high (50-70%) and after some searches I found that someone else posted in a different forum (I think it was the S6 Active forum) that the issue was related to multicast being enabled on wifi routers. I disabled it on my fios router (it's in a hidden menu) and it resolved my drain. I am now at 12 days uptime without a random drain. I also had to disabled Enhanced LTE as that was causing a HUGE drain at times when I didn't have LTE. I hope this helps.

Droid Turbo dies at 4%

My Droid Turbo was at 4% and displayed ''powering off'' and it turned off shortly after. When I tried to turn it back on, it displayed 0%. But when I plugged it in to charge, it displayed 4%. Any idea on whats going on?

Anyone have a solution????

I understand that when battery gets old, it may be getting unable to correctly reflect the remaining power as it reaches zero. If that happens, the only way to rectify is replacing it with a new battery.

I've only had this device for a few months. So I don't know if that's it. Does yours do the same thing? Please get back to me.
I'm running the latest marshmallow update from March if that matters too.

Mine does the same thing, at even higher battery % than 4% (usually around 15% or so).
That seems to be normal. I don't know when it started, though, as I avoid letting the battery get that low.

Quick question. Are you on a custom or stock ROM when this is happening?

Custom (lineageOS), though it happened on stock as well.

Are you sure you got the device brand new unused? It is not a new model so even if you get an unused one, the battery may not be as durable as a new one. But I would say unless you abused the battery in these few months, it would not have gone bad this quick.
Although mine can't hold charge as good as before, after 2.5 years of use it can still last for one day. I seldom let it go down to 1%, but the case you mentioned have not happened to me. But this is a rather common problem, across different brands of devices.
