Help…. My Tab S 700 is overheating… Need advice. - Galaxy Tab S Q&A, Help & Troubleshooting

My Tab S 700 is overheating and getting terrible battery life. Does this even after reflashing.
Its over 30 days old, and is rooted and debloated, but still stock rom.
Can I still get it services under warranty?
What is my best option?
Should I unroot it?
Need some advice. Thanks

Check for CPU load and wakeups

It seems to overheat under normal loads, cpu at 1600ghz an up, loads 70 percent and up.

Battery life is ok if asleep, but awake barely lasts an hour browsing or playing game, if it doesn't lock up first.

I flashed thunderom. Battery is so much better after installing it and doesn't overheat no more.it might be some apps that you installed or may be the hardware. What apps have you debloated and installed? When you first got the tab s did it have these issues before? I would suggest deleting some apps or factory reset or flash a different ROM. It could just be apps that are running in the background that you installed.

[Q] S3 Battery Drain after Jelly Bean

So I searched all day for an answer similar to mine and I did not see what I could do.
I was on rooted on ICS until this weekend when I updated to Jelly Bean and rooted again.
My Battery usage was working fine in ICS, what I would call normal battery drain.
After the update I am getting terrible battery use!!!!
I have tried closing, diabling all apps, radios, I have diabled bloatware.
But my battery keeps draining at a rate of 10% and hour!
All this with minor use.
I have opened a few apps and the Play Store but nothing else.
The S3 has just be inJust in standby.
In the settings, under battery it show my main power consumption is the SCREEN at 60%
I dont know how!
When the screen is off, I dont have a video wallaper and when I do power up the screen its so DIM I can hardley see anything.
All this happened after the Jelly Bean update!
Any idea on what I can do?
Do you think a factor restore would help?
Yes, back your dat up first though (contacts, calender, ect.) because you will have to redownload your apps. I did a reset and was on stock after updating but still had terrible battery life. The fix? Take the battery out 40 minutes, put it back in and run it COMPLETELY dead, and recharge it while it's turned off. Make sure you have time to do this without needing the phone because it takes a while. Like 7-8 hours. I've went a day now without much usage at all (still at 90% charge) and have a day left on standby. The battery reset helped more than anything I believe.
Yep same as mine jb update has a heavy battery drain..and my skyvalex callrecorder stopped working..i just flash back to ICS.

My opinion, factory wipe and Re-root it.
Install SetCPU and the Ktoonsez kernal to manage the power settings. Also Go Power Master is a good app to tweak power settings.
In SetCPU you can have it clocked down when the screen it off.
Had the same problem. Called att went through the ranks until I was told by att warranty supervisor that they had no work around and I should root my phone. Shocking they told me that. But I found the problem. I uninstalled the update to Google now and then shut it down. Battery seams to be doing good now.
Got a free battery from att though. I guess cause there higher ups have no idea how to fix drain.

Luckily your type of phone has a removable battery....unlike me...cannot replace to a higher battery capacity

Semi-solved
I somewhat have solved my problem.
What I did was Factory Reset from the Setting menu. I thought I would have lost Root doing this.
It was already set in my mind to just wipe the S3 clean and start over but the root did not get washed out.
So, I used Kies to only restore my contacts.
Instead of having any old apps restored I downloaded them all over again from the Play Store.
So far so good!!
I have better battery life than prior to the reset.
I had been losing 8% and hour in Standby and 10%+ when in use.
So far today I have used the phone with my screen brightness high, made about 10 calls, surfed youtube and I only down 6% in the last 2 hours.
I consider that better.
If there are some things I can add to my diable list that you all know of to give me an EVEN BETTER result please let me know!
Poor battery life here too. Battery settings says screen is eating 78% and Maps eating 10%. I'm a heavy user but its mostly surfing this site and Facebook. I don't play games or watch YouTube much
Does this solve the battery drain issue?
Hiya all.
I haven't got a S3 so I can't confirm this works.....
A friend was having the same battery drain issue and I was going through his settings and noticed that "Sync All" was on.
Turned it off and the battery drain stopped. We think.
It seems to easy to be true. So I'd like more S3 owners to try.

Hi have the lte version that i got couple of days back and i have the same problem. I have not rooted and it came stock with jb. So you have to do a factory reset and remove the battery and try or just the battery?
Also how to remove some stock apps, I don't use any.
My battery life stinks. I had to get the Mophie case with extra battery built in. works great

Cyanogenmod 10.1 terrible battery life

I have recently installed cyanogenmod 10.1 onto my galaxy s3. The battery life since then has been very poor. If I leave my phone on without even using it, it drains about 1% every couple of minutes. When I look at the battery it says that the process of "phone" is taking up a huge amount of battery. Can anyone tell me why this is or how I can fix it?

Generally these issues are user related and not ROM related.
I was so frustrated with some of the ROMs when I first started out but then realized I was doing a few things wrong (mainly because these ROMs, including CM10 have very decent battery life).
First, I would recommend a clean reflash:
factory wipe / reset
wipe cache (some say twice)
wipe dalvik cache
install ROM
after rom loads, wait 5 minutes (don't touch at all) then reboot
now you must wait.. sometimes it takes 24 hrs or so for a ROM to correctly load.
Not sure how true it is, but some say to now drain battery down, then fully charge.
At any rate, I follow these steps all the time and works great!
Also, keep in mind that most of battery issues are user related.. so think about what settings, apps and kernels are being used on your end before question a ROM. This is why waiting 24 hours or so before installing all of our "crap" will give give the ROM more time to settle.
Hope this help!!!! Happy Flashing
Thanks for the reply. However, I have looked at what apps and processes are draining my battery. And it appears it is the "phone" process that is doing this.

Just to piggyback on spenny88's reply, exactly what did you come from (stock?) and how did you wipe and flash?
This is all key as to how well your device will perform.

I have noticed something similar. I am coming from stock. I am going to guess my battery life is in the neighborhood of 10% less. I wiped everything before I installed CM. That said, this feels so much faster than stock.

Having the same issue with my Samsung Galaxy Tab P1000 (p1 in Cyanogenmod). "Cell Standby" is taking as much juice as "Screen", and I am using Wifi only. I don't even have a sim card in the device. Wish there was a way to disable Mobile Networks without disabling Wifi via Airplane Mode.
I installed through Rom Manager as upgrade from CyanogenMod 9.1 with wipe. I will try the recommendations above and report back.
Try the latest nightly (or RC4) of CM10.1. The battery life has definitely improved a bit.
Samsung Galaxy s3 intl battery drain cm10.1
I recently installed cm10.1 nightly on my international S3, it has cut the battery life down drastically and seems to drain over 10% an hour, even when not being used.
I've tried everything that i've came across by searching and still haven't had any real gain on battery life. Doing a full wipe and reinstalling doesn't help, and i've given it time for battery to calibrate; no difference. Even with wi-fi and location services off i'm getting a big drain. I've even tried switching to Slim Bean, if anything the battery was worse still.
Firstly i'm getting that Android OS is eating up a large chunk (usually above 60%) and using BetteryBatteryStats i don't see anything out of the ordinary in terms of partial and/or kernel wakelocks. I really don't wanna have to put the stock Touchwiz rom back on but that seems like the ways it's going. Any help would be greatly appreciated. Is there anything else i can try?
i find i get terrrible battery life on AOSP when i restore google through the setup. i skip thru the installation and open the play store to enter my gmail. then, before restoring my apps, i let it charge to 100%. honestly AOSP still doesnt have decent battery life, but it does improve if you play with it and try different things

I would respectfully disagree with you. I have run a number of ASOP based ROMs and find them better than stock in terms of battery life. Certainly better in terms of not making my eye bleed (as I hate touchwiz, but that is a personal preference). I find that SlimBean gets me the best battery life of the CM based ROMs.
To clarify, I get just over 1%/hour battery drain, when idle (as measured by BBS) with GPS and google sync enabled, mostly on LTE. My phone happily spends almost all the time I am not actively using it in deep sleep.
The recipe to achieve this is to disable google location reporting and history, avoid tons of widgets that constantly update themselves, disable samsung services that you do not use, and monitor battery usage to look out for rogue apps that do stupid thengs, like hold wakelocks when they should be idle. Dropping the minimum frequency to 192 MHz, and going to ASSWAX (CPU scheduler) and ROW (I/O scheduler) also helps.
To get decent performance you do need to install things properly. Which means ensuring that you don't have conflicting settings or random leftovers. I tend to dirty flash updates but you reallly do get better and more consistent performance going through the pain of a complete clean install (format system, clear cache, reload apps from the store) when you are switching ROMs. Only use TiBu to restore app data. Once you do this, in my experience rogue wakelocks are the biggest cause of lousy bettery perfromance, and you can track down and eliminate these. I have around 150 apps loaded and do not run any task manager/autokiller. My phone typically runs without any reboots or power cycles between ROM updates which equates to rebooting every couple of weeks to a month. I have seen over 2 months of uptime.
Certainly should be able to go 16-20 hours between charges which I would consider real world all day functionality. I guess my point is that rock solid stability and all day battery life is possible if you are systematic about how you do things.

[Q] N5100 Battery Life

Was skeptical about the N5100 battery life since it only have 4600mAH battery.
Now that I have bought it, it seems my worries are confirmed.
I'm running stock rom, only rooted it without other modification.
Installed and have greenify running. Not using any sim card, only using it on WiFi.
Playing a video using MX Player, drained up about 20% of battery for a 45min video. That's rather heavy imo.
Normal browsing and reading forums eats up about 4% per 6min of use.
Is this normal? Or is it my battery has significantly degraded? Cuz I bought this 2nd hand 8 months old.
Btw the above test were with Power Saving mode(CPU and Screen) and screen brightness was at 25%~30%. Currently on 4.2.2.
And does using the S Pen eats up significantly more battery?
Thanks in advance for the feedback.

Do a search on battery and charging by me, in the Q&A threads. I won't repeat myself here, but I go into how to correct drain issues. Many developers will push their apps for calibration. The real trick is discovering what is doing the drain. I have seen for myself how one app can do a lot of damage with media. Normally I get 12% per hour on battery usage while Miracasting Netflix to my tv, and about 10% on normal usage with WIFI always on. I have MXplayer and a bunch of apps as well running so I am not going to get the same power savings as with a cleaned up stock ROM without any apps, what would the point of having a tablet if that is the case???? I guess peeps like to show off when it comes to numbers. I like to show off when it comes to usability and function without all the apps get in the way.
my battery stats
I'm running CivZ-FLEX-BEAM-REV3.6.2 ROM.
Installed and have greenify running. Not using any sim card, only using it on WiFi, even off the WiFi before I off the screen.
Even use underclock to 1.2Ghz cuz only used for normal browsing, nothing intense that require more power.
Here's my battery stats:
Is this normal? Or is it my battery has significantly degraded? Cuz I bought this 2nd hand 8 months old, now 9 or 10 months already.
Now considering should I replace the battery or just get a powerbank to help.

From what the graphs show... it looks like the battery could be going bad, as there has some that say Samsung is aware of bad batteries in some units. You could contact them, but you will need to un-root if sending to Samsung for repair.
Since you are rooted, I suggest installing xposed framework and install Wanam DVFS Disabler for Xposed. It is a standalone utility from the complete Wanam xposed app. Once installed make sure both xposed is functional, and the app in xposed is enabled. These apps act as a separate process from the OS. So installing them requires user interaction for activation and updating, along with a reboot most of the time.
Once they are running... it is best to turn off the tablet for 1 minute and then plug in the USB charger and wait til it is showing 100%. Then turn on the tablet. You can unplug the USB power cable and wait 1 minute, then plug it in. Take note if the charge takes less than a minute to get to 100%. If it takes a minute or more... you will need a stop watch, as it should take about 15 to 20 seconds to go to fully charged, unless you have music or media running at the time. If it does charge quick, you can then disconnect and do another days worth of use and check your stats. Hopefully disabling DVFS will cure your issue if it is not battery related.
As for unrooting, make sure you do a clean uninstall, and have any apps that require root uninstalled. If running triangle away uninstall that as well. You may have to check within the apps settings to make sure you uninstall properly, as to uninstall from play store or the system may not properly remove the app.
Updated Battery Stats
this is my updated battery stats, now I'm suspecting it maybe due to calibration problem?
My screen on time is now 2 hrs 45 mins, and for the last 45 mins it has been running on that last 1% of battery(but with screen dimmed, as brightness is automatically dimmed and can't be adjusted when below 5%).
Even until now the device haven't auto shut down due to run out of battery yet even though been running 45mins SOT for that 1%.
Calibration problem? I've tried calibrating using calibration apps, which I charged to 100% then press calibrate, but didn't help.

Sudden drop of more than 3% at any level after doing the DVFS disable and properly charging can be one of two things.
A bad battery, or bad charging cable. Yep, I have had two bad Samsung cables, one did exactly what is happening with you, and the other did a melt down at the USB connection on my tablet. If you have a good cable from a Blackberry or a Sony/Ericson device, you can try that. I have moved over to Sony Xperia cables, as they are pretty well built and longer.
If another cable does not solve your issues, I suggest unrooting and cleaning up rooted apps before having Samsung service your tablet. It very well could be a bad battery.
thanks for the reply, I think I'll just resort to sending it back to Samsung to fix it.
Now I have made a nandroid backup already, then I flashed stock firmware, so my device is now unrooted and on stock firmware, however my flashcount is still there, and now I can't run triangle away cuz my device is unrooted already.
If I were to root it, it'll flash custom recovery again then it won't be on stock firmware anymore.

Your unroot sequence was done out of order.
Set USB debug
Root stock rom with saferoot.zip
Install triangle away
perform clear of counters
Verify after clearing in about device that custom is not set.
If so make sure triangle away is set to clear and perform clearing.
Remove triangle away
Remove SuperSU through the settings, clear for reinstall.
To make sure everything is proper... do a factory reset.
Once those steps are done, your tablet should be stock and able to perform OTA or Kies updates, without any issues with counter and root.

All of a sudden CPU is at 100% non-stop, help!

All of a sudden my CPU is running at 100% non-stop. Using Trickster-Mod I can see this and my phone is extremely hot and my battery drains in about an hour.
I used better battery stats, CPU Monitor, GSAM... all show normal battery usage, no apps or processes using more CPU or battery than normal. I'm at a loss, anyone have any ideas?
Thanks,
Justin
Chances are it's a rogue app. Process of elimination, remove anything you've recently installed.

What if anything have you changed using Trickster? I'd maybe uninstall that and clear cache/Dalvic and do a couple reboots and see if it's still acting up.
Of course there's the Factory Data Reset option too.

Thanks for the help guys. I tried tracking down an app but I hadn't installed anything recently, just some updates, I froze all of the possible offenders with Titanium Backup and still had the problem. I hadn't made any changes to Trickster in a long time but I tried that and it didn't make a difference either.
So... I ended up backing up everything with Titanium Backup and installing SkyDragon ROM... that fixed the problem.
Thanks again for taking the time to try and help.

What do you do to reduce your Tab S power drain?

I have a SM-T800 on CM12.1 that averages a current drain of around 60 mA during deep sleep. I also have a OnePlus One that averages around 9 mA during deep sleep.
I'm using Battery Monitor Widget Pro with the "Android mA" setting to get my readings on the SM-T800.
Obviously, there's quite a difference there. The SM-T800 draws almost 7x as much current while it's doing nothing - no screen on time.
It makes me think that there must be something I can do to reduce the current drain, especially with a rooted device. But, I haven't been able to figure out what.
Has anyone been successful getting their battery drain lower? If "yes", what have you done?
Thanks,.

Did you forget the thread you made 2 weeks ago.
http://forum.xda-developers.com/galaxy-tab-s/help/sm-t800-barry-drain-t3157867
John.
Yeah, @Tinderbox (UK), but since the title was messed up I didn't think folks were looking/responding/searching to the older thread.
I think this is still something we can all benefit from, if someone has figured out a way to get our power consumption down. And if someone does respond back to this thread, other folks will be able to find it when they search now.
I use Euphoria OS and debloat it, that gives me a few weeks of standby if it's just sitting on a shelf. Ensure you delete Trebuchet (replace with Nova/Apex/etc) as it sucks a huge amount of CPU power when idle.
If you can run without GApps you'll maximize the savings.
As i said last time my T800 only used 1-2% in 16hours what ma does that work out too, the battery is 7900mah
7900mah/100 =79/16*2=9.8mah
Every time you install an app, it can make an huge difference, if it stops your tablet from sleeping.
You need to check your wakelocks to see which apps are keeping your tablet from going into deep sleep, auto check for emails, sync, alarms will cause your tablet to come out of deep sleep.
John
Thanks, @Tinderbox (UK).
As a test, I decided to wipe out my current installation, and just load the latest Nvertigo SM-T800 ROM and the very minimal nano Open GApps. I had to load a few minor things beyond that to get functional (KeePass Droid, Opera, MyBackup Pro, Wakelock Detector). I disabled all Google account sync items.
I disabled Trebuchet wake-ups, and set autostart off (Thanks, @fraser.dk)
I'm still seeing about 1% drop every 4-5 hours.
Nothing stood out from Wakelock detector. After 24 hours of the tablet sitting idle, the wakelocks were all less than 30 each.
Are you running a specific ROM or Kernel?
I am on the Stock UK v4.4.2 kitkat rom, I have never flashed though i am rooted.
If you are rooted, try the app in the link below, it link to XDA and you can download a version of cpu spy reloaded, it works great at spotting wakelocks it`s the only wakelock detector i use now.
I am running an Sony App that is supposed to stop all wakelocks, it`s in standby mode, you can whitelist apps if you like, I am not certain if it`s doing anything at the moment, you need root and exposed installed.
http://www.xda-developers.com/optimize-battery-life-with-this-useful-app/
A 1% drop over 5-6 hours is not bad.
John.
So i have an result on the Sony Battery App, I put my Tab S into sleep mode at approx 12:30AM it was at 69% , I woke it up at 6:50pm, it was still on 69% after 17hrs.

for me i have downgraded back to stock kitkat 4.4.2, debloated, rooted and xposed installed, and use powernap, i can use the tablet all day and still have between 45% - 60% battery left depends on if i am playing games or not... i have tried so many apps and custom roms in lolipop and none of them have good battery life....
PowerNap which is the Sony app i use, only reduce battery drain in sleep mode, by stopping all wakelocks, it does not reduce the power that games or other high drain app require, so how does you battery last longer, how much power were you loosing overnight when you tablet should have been sleeping it must have been immense.

on kitkat i had no major battery drain, i just like having powernap on my device... on LP like i say even just using the tab battery would drain like 1% every min... just doing typical web use... i have tried everything to get good battery life on LP but nothing works for me at least.. but with KK i have no issues...
A lot of people say they have had no problems with lollipop, but there is an significant number that have reported problems after upgrading, I decided to stick with kitkat and await android m.
1% a minute just browsing that`s bad.

I think I'll try going back to KitKat, and see how things go.
I have been frustrated on how fast the battery drains when doing minimal tasks, like reading an ebook (about 1% drain a minute).

that how it was for me... 1% a minute.. i like kitkat and very happy with it does what i need and awesome battery life..
Bummer.
I installed the Canadian stock KK ROM (T800XXU1ANJ6_T800XAC1ANI1_HOME.tar.md5) onto my US SM-T800, and it's boot-looping.
I thought I should be able to load the Canadian version without any problem.
Is there a way to turn the tablet off when it is bootlooping? I don't want the battery to drain while I'm downloading another ROM.
Try this to stop boot loop.

Thanks, @Tinderbox (UK)!
Out of the bootloop now, and setting up KK.
What do you do to prevent OTA updates? I have TWRP installed via the All-in-One Auto Root.
If you are rooted you will not get ota updates, if you are not freeze the updater an tab s owner did that with an app called "package disabler" it works without root but the free version keeps being removed from google play store, the full version is £2 (£1.50) just reduce.

@Tinderbox (UK) WHAT KITKAT ROM YOU ARE USING ????
stock UK kitkat rom v4.4.2, Lollipop has been out for my T800 10.5" for an couple of months, but it is full of bugs, and quite a few people have went back to kitkat.
Kitkat has been solid for me, I ran it for 164 days continually, I never rebooted or shutdown in that whole time, no problem at all.
