[Q] Battery empty over night while switched off - Galaxy Tab S Q&A, Help & Troubleshooting

I had this 2 times this week. I switch it (SM-T705) off in the evening at 100%. On the next day battery completely drained.
On the 1st time (battery=0%) I even could not switch it on - had to press POWER+VOLDOWN+HOME. The 2nd time it started normal (8% rest).
Battery monitor app said, no data for 12 hours (during the night = as it was switched off)
I use SkyHigh ROM+Kernel (4.4), Xposed, Wanam (incl. soft reboot menue,...), Greenify. As a first measure I uninstalled Greenify and disabled Wanam.
I found several post on the web regarding this issue, but no real conclusion. Any idea to get closer to the problem would be very welcome !

Have you tried Watchdog, it will sound an alarm if any apps use above a certain cpu usage, this will find any power sucking apps, go in to the settings and set it to monitor all phone processes.

Have a look at the thread below, and install the latest version of the app, this will alow you to see what apps or process are keeping your tablet from going into power saving deep sleep.

Greenify doesn't really do anything that android doesn't already do itself. Its just another app running in the background. How are you powering off the tablet?

This is sure caused by kernal wake locks.
Why don't you try "better battery status" app and find out what it is draining your battery juice and

It has the reasons and remedies for your problem. Good luck.

THX for your replies, but it is about DRAINING BAT during POWER OFF

Some times I face a similar problem like when you reboot your phone battery reading suddenly drops from say 80%-62%.
And every time when it happens i do this...
#Switch it OFF
#Connect it to the charger cable and wait for the reading to show. You will see the actual reading. (some value closer to 80% )
#switch it ON without disconnecting charger cable.
and I get this funny smile on my face
Try it and let me know if it helps.

Thread cleaned, guys lets please keep things on topic.

I'm having a similar (?Battery?) Problem
I didn't use my Tab S for a couple days (unplugged but OFF) and when I went to go use it...... it was (& still IS) totally "DEAD". It hasn't responded to anything I've tried so far.......
~~ Hold [POWER ] button for over a min
~~ Hold [POWER] & [VOL DOWN] together (This worked one OTHER time, not THIS time though)
~~ Hold [POWER] + [VOL-UP] + [HOME] together (Like the "Wipe Cache Partition" sequence)
I heard that there is somekind of "glitch", that if the battery(ies) drop below 3V, it won't take a charge anylonger..... well ACTUALLY, it won't RECEIVE a charge from the Tablet anymore.
(From this YouTube Video....)
"Samsung Galaxy Tab S 10.5 doesn't turn on fix" ~ Chester Lowrey
He pulled off the back and "tapped into" the battery connections with a decently rigged up charger. Charged it up past the 3V "min level" and it started working again.
Has ANYBODY heard of this issue or problem??? And IF SO....... any other SOLUTIONS?? (I HAVE searched but haven't found anything about this in XDA......YET)
My Tab is totally DEAD and I really want to avoid sending it in for warranty repairs. Any help would be MUCH APPRECIATED!
Thanks, Joe (This is my first post here so I HOPE I'm in the right "place")

You're in the wrong section, you need to go and ask in the Tab S section.

Whooooooops, that was a huge derp on my part! Dunno what I was thinking there, sorry.

The battery protection might have kicked-in it disconnects the battery when the battery voltage drop too low, normally between 2.5-3volts per cell, and you need an charger that can reset the battery to make it work again, I dont know if Samsung has some sort of procedure to do this, I have heard of another Tab S owner who had an dead tablet like this, he took it to an phone/tablet repair shop and he says they connected an box to the tablet and it started straight away.
Have you tried the procedure below, it is slightley different to what you have tried before, if it does not work, try connecting the Samsung charger and try again.
1) connect the tab to PC
2) press Home, Vol Down and Power simultaneously up to a screen appears;
3) press Vol Down to cancel and reboot the tablet.
Also read the link below, and give the bump charging a go.

I had a similar problem were my battery from a full charge would last about 30 mins,it done this quit a lot,took it back to PC World they sent it back to Samsung who said the battery was faulty and replaced it,only had it back a week and after only one charge this new battery is doing the same thing,it will not last more the 45mins from a full charge,it is going back to PC World on Monday.Cheers Longlegs

I read a few posts (I think HERE) talking about bad/loose battery CONNECTORS.

I've had the same problem. Heavy drain, battery discharged when power off, slow or fast charging time. This morning,when i tried to disconnect the battery, the connector just came away from the board!! It is really really bad soldered, resoldered by myself now seems to be working! Before soldering 50%batt,after 60%,used a lot today with chrome,youtube,twitter,display on just to check,now i'm with 22%
Edit : After about 9hours from repair it's fully discharged. No drain when in idle

Serious Jasjar battery life issues....

Hi all,
I've just spent a good amount of time browsing these forums - lots of good info here!
I've got my hands on a free i-mate jasjar from work as it is having battery issues and they just upgraded the user.
The issue is that it drains the battery in about 3-4 hours - thats with no sim in, phone / wireless / bluetooth turned off, very minimal use. We got a new battery for it in case that was the issue but it still loses it...
The other ones we have at work get at least a day / day and a half depending on usage.
I've reflashed it to the latest i-mate firmware (1.30.76 WWE) but stilll no luck....
Aside from sending it off for an expert to look at - does anyone have any suggestions on what i can do to diagnose / fix the problem?
Cheers
Sam
disable activesync checks
in wm5 activesync checks every 10 minutes or so for new data even if you do not have a server installed.... so.... here are the steps.....
with the device disconnected from the computer !
1. click "start"
2. click "programs"
3. click "activesync"
4. right soft button "menu"
5. click "add server to source"
6. fill in "1" in every field clicking "next" as you go through the proccess! (or any other fake data you want)
when you get to choosing what to sync, uncheck everything and click "finish"
7. right soft button "menu" again, now you'll have "schedule" lit
8. click "schedule"
9. change both drop down menus to "manually" and uncheck s"end outgoing items immediately"
10. click "ok"
11. right soft button "menu" again
12. click "options"
13. select the "exchange server", click "delete" and "yes"
14. click "ok"
YOUR DONE !
the device should last a lot longer !
have fun !
p.s.
don't forget to disable IR so the device won't try syncing with the sun ....
Great - I've set it up and will test it out over today - thanks for the reply
Make sure your infra red is also off, receive all beams is unticked.
Presumably you're not using any over clocking software? They disable the idle mode detection so make the battery less efficient, even at slow clocked speeds.
V
Infrared is off, currently its got fresh firmware as off yesterday, charged overnight - no sim, every conceivable option turned off, no extra s/w installed.
Since 9am its now down to 85% - roughly using 10% per hour with zero use....
I have the Same Issue ,the battey use very fast .
at the first I think may be is the net lock make that, But yesterday ,I try to use the unlock tools ,but same as it.
the charge complete. close all function ,can't use more than 8 hour's.
I've the same issue,...change a batery with a new one, BUT when it goes les than 70% all the problem start, loose the phone signal, shot down....I've a official Qtek 9000 ROM of febr. '06

I think That's the Radio or Hard device error.
If other Rom have not This issue. I think that's this rom make it .
There are a number of threads regarding batteries and new ROM versions and I think the concensus is that its the battery and it is just coincidence about the new ROM.
I have had my device for about 8 months and it has behaved well until a few weeks ago when it started to shut-down at 70-80% battery. The shutdown only occured when I had a heavy drain on the device e.g. when using GPRS or phone and I started to think that the battery was dying and the heavy current drawn by the radio caused the battery voltage to drop below a sustainable threshold for powering the device - hence the shutdown. £20 later I have a new battery (from eBay) and can go 1-2 days without charging. I am leaving the old battery on charge for several days to see if it can be salvaged

Thank you help, But I return to the old version ROM. the batteries is OK. I don't know how to explain them
Try measuring the power consumption with acbPowerMeter and post your results so that we can see your device indeed has problems or not. See my related articles for more info (cross-posted to the General forum in here).
My Universal power consumption
With BT on and Wifi off power is at 642 mA...
Is it bad or good?
durius said:

Click to expand...

What that's mean?
it means that the device has bt turned of, and also wifi turned of and acbmeter indicates a power consumption of 642
I also seem to have started incurring a problem with battery, it is shutting down the device at 50%, and yes there was a slight draing GPRS and Push Email running, and trying to make a phone call.
It only really happened today, and am at a loss as to the cause. I would guess, the battery is 1 year old and probably needs replacing.
i have been using two different 3.2 roms ltcmdr, then jw's for a while now and no problems until today.
I suspect its the age of the battery. I am in the process of trying to suck the battery down as far as I can, then recharge it.
It appears to do a complete shutdown every 2% from 50% to 40%, I am now trying to get it to less than 40%.
My original battery lasted me for about 8 months when I started experiencing the shutdown / hanging problem whenever the charge would drop to 35%. I replaced the battery with a new original battery and all went okay. Unfortunately my second battery is only 5 months old and I have started experiencing the same problem again although this time the problem is occurring at a charge level of 15%. When the battery reaches this level and I try to connect GPRs or make or receive a call the unit hangs. If I try to soft reset I cannot do so till I connect the external charger.
I think such a low battery life is simply unacceptable.
Regards
Ever wonder how a battery tells the system that it is full and to stop charging?
If you get a new battery, take the old one down to somewhere below 100% -then install a new ROM and see what the battery meter reads after the hard reset.
The system must recognize a point which would be monitored and recognized as "full battery". When installing new ROM's, the system takes the battery power at the time of the install as 100%. This is why it is reiterated in almost all ROM upgrade instructions:
"Your device battery must be fully charged before installing this ROM".
However, I'm not so keen as to have a fix; but I've noticed that when the battery is fully charged and the device is then unplugged, turned on and then off, then plugged back in...it seems to charge alot longer than what I would expect necessary to reach 100% once again.

battery issue

hi guys,
i just checked out my ARTE160 battery. when i checked out the output voltage, i found that its 3.95~4.2 v when full charged. i jus checked this out with a multi meter. the battery is designed for 3.7v only, so does this mean there is a prob???
thx guys
I'm not a pro, but I think this means that everything is alright with the battery. I would rather worry if the voltage was below 3,7 V - that would definitely mean a problem.
well i find wat u say is logical but still im having some small prob in my phone.....
it keeps working well and suddenly the phone service alone wont work and gets hanged (means no calls and sms) after couple of mins mobile just researches the network and joins.
the prob is when this thing happens and someone calls me the call is ringing but i dont get any ring or alert in my mobile.......
also sms is not delivered kater but is lost completely......
i jus looked out somewhere that these probs may be due to battery........

I've just chcecked the output voltage of my battery - when 45% charged - the voltage was 3.82 V.
in my opinion, your problem has nothing to do with the battery. I had same problem that you described - I switched to WM6 from WM5 - it did the trick.
now it hangs very seldom.
I guess that would help you (at least if you're using WM5).
oh but im using 6.1 at present
its TOM'S ROM.....

*for battery issue;
buy a new battery and
charge <----- device must be off!...
when green led light shows, its done..
this should sort your battery issue..
* for issue with - ''suddenly the phone service alone wont work and gets hanged..''
try a hard reset, if it still happens, open the device - open through the back of the device and simply give it a clean, ensure all connections are connecting, in other words, scratch the pins inside device if they need it.. assemble correctly and hope this helps..
-use cotton buds, the ones you use to clean your ears with..
-use a pin/needle to scratch connections..
*sounds like a hardware issue, not rom issue so cleaning inside the device is recommended..
*I've fixed my p3300 plenty of times now by just simply cleaning inside it.
- including the ''not charging'' and ''no sim'' issue people have experienced..
Not charging
HI Geeks, I have a problem with my blackstone battery. It is getting charged only up to 50 to 55 percent. I kept on charger for one ful night. But no use. I am using official ROM. Can you suggest any solution for that?
Help PLZ
I tired both the charger and the USB cable. Still the problem remains.
A new problem
Now i am facing a new problem. When i switch off the Touch HD, it will not start. When i press the power button, it shows "Smart Mobility" then it will go off. I tried once and pressed the power button again. It lasted some more time, reaching to the HTC logo screen.
Then I Connect the phone using the usb cable to the desktop and press the power button. WOW. it started without any problem. Can you help me to get around this problem?

The problem is that at the tablet the battery lost a charge and because of it there was a failure in its work and it got to sdcard mode. Now the battery has no enough charge and therefore electronics of the tablet doesn't work correctly - not possibly to charge the battery and it isn't possible to turn on the tablet. The correct solution - to provide a battery charge above of minimum admissible level. But as electronics of the tablet doesn't work correctly, also the battery charge isn't possible. For a solution, it is necessary to disassemble the tablet, to switch-off the battery, to connect the charger and when on the screen to appear drawing of the battery then to connect the battery. After that the battery will accept a charge well and you will be able then to turn on the tablet after the battery is charged.
Here is the original post with solution for the same Tab, but with a screen 8.4 (Russian language):

Hi. Im Scared of sdcard Mode. Do i need to let the battery drain at all, then connect tablet with charger and then power+vol.up+home?
What will happen?
Will it boot to system, to recovery or it will charge like normal and then boot like normal?
Please answer me

Let the battery completely drain then plug in charger wait for around 5mins then it should boot.
Porcelana my t900 got stuck in sdcard mode today. I found this thread, followed your directions and it worked like a charm.
I have no idea what sdcard mode is.

It was probably unnecessary to disassemble the tablet.
Simply letting the battery discharge until it turns off usually suffices.
this has happened to my tablet 4 or 5 times now. it does work but if I leave my tablet for a little while it does it again and again. do I need a new battery? I can't figure out how to open it either. I don't want to break it.

4/5 times? I think you should refresh your tablet and flash the stock firmware.
It's happened to me just the once.

[Q] [HELP] t210r (wifi only, US version) shutting down on its own

auto-shutdown, more than 50% battery remaining; a long press of the power button runs the boot up process; a short press does nothing. this happened while I was watching a video (local, not streaming)
since the tablet was kinda warm, I used a utility I have on it to see what the temperature (of what component, not sure) was, 37C / 95F -- I don't know what the setting is to trigger a thermal shutdown, but it will boot up right away, which isn't what I'd expect if it really was overheating..?
has anyone else seen this (or similar) behavior? rooted, running 4.4.2 stock
tia, RA
I have 3 of them here that no longer boot. It's a sure sign that the Tab will get to a point where it will no longer boot at all. If you find anything, let us know. I'm still trying to figure this out. It seems that when your Tab finally get to the point of 10% charge, it will probably never not correctly again.
I'm still under warranty, but the Samsung website is a total PoS, imho, as far as trying to find anything useful with regard to my situation....
otoh, it hasn't happened again, so keeping my fingers crossed that my presumption (bad idea to watch a video after playing graphic intensive game for a while) is adequate to keep the Tab working well enough (in all honesty, it was never a cutting-edge device, imo).

since the tablet was kinda warm, I used a utility I have on it to see what the temperature (of what component, not sure) was, 37C / 95F -- I don't know what the setting is to trigger a thermal shutdown, but it will boot up right away, which isn't what I'd expect if it really was overheating..?
has anyone else seen this (or similar) behavior? rooted, running 4.4.2 stock

really, not the same at all. my tab is fine now, and even when it did the shut-downs, it booted up fine. I don't know if things will get worse, but for now, I'm having no issues.
hope you can get some answers.

Battery Issue After Update, and how to solve

Some people might have experienced a battery issue after the latest update. It can be solved quite easily. Even If you don't believe you have an issue with your battery, you should try this as it seems baked into the update process.
Just to describe my experience first. After update my battery was going from 100 percent to 20 percent in about 8 hours while idle. It wouldn't charge while it was on. I would have to turn off the phone to charge it. I could not figure this out, until I found similar issues on different phones in the forums. It seems that when an update gets pushed to your phone, and your battery is low, your current battery charge is cached as 'max'.
First I thought the connector on my charger was broken. Then I thought maybe the charge port on the phone was somehow damaged. Then I thought there was possibly a foreign object in the charge port. It is actually none of these things. It's a software issue. Here is the resolution.
You want to boot into recovery mode. This is taken directly from Lenovo's website on the Turbo 2, but please read my caveats at the end.
Power off the device and unplug it.
Press and hold the Power and Volume Down buttons until the device turns on.
From the Boot Mode selection menu, press the Volume Down button to scroll to Recovery and the Power button to select it. The device will restart.
An image of an Android robot with a red exclamation mark will appear.
Press and hold the Power button, while still holding Power, press and release the Volume Up button, then release the Power button.
Use the Volume buttons to scroll to Wipe Cache Partition and press the Power button to select it.
If an additional confirmation screen appears, use the Volume buttons to scroll to Yes and the Power button to select it.
Press the Power button to select Reboot System Now.
This is basically the process, but you have to change up a couple things. After you wipe the cache, select 'turn off' rather than 'reboot'. Give the phone a minute to be sure it is entirely off. Plug the phone into a charger in the off state and let it charge fully. Once you are certain that the phone has been charged to 100 percent, you can reboot phone. Voila, back to almost 2 days worth of battery life.
It doesn't work for me, anyway thanks for sharing this info.

I wrote this for X Style but it can be aplied to Moto x Force in the same way:

I am having this issue, and sometimes Ampere shows the current draw at 2A even though the only thing I've done since power-on is run the Ampere app. I also have the green lines but that's been for much longer, so maybe there's a short but the issue started after an update not with the green lines. I'm suspecting something like a radio bug but unfortunately BetterBatteryStats requires root to do any real useful analysis (not possibly yet that I've seen with the VZWDT2). The only thing showing under usage is screen-on.
Wouldn't be ironic if it were an as-yet undiscovered crypto-miner? That hacker would be able to earn a huge bounty if they found permanent root.
Same problem here, any other solution? What's the best app to diagnose what's draining the battery?
I have done every thing with my turbo 2 , all given your tips i implemented on my mobile,
but still my phone battery not working well like working before update nougat. after updated nougat my mobile battery draining fast and after full 100 charge my mobile battery just work 3 and max 4 hours.
please launch any new update to resole this battery issue or give me some best tip to improve the battery work same work as before update nougat.
We are motorola users and we love this but company not support our users to actual solve this bad issue, really bad.
hope i hear from you with good news for users.
thanks & Regards,
I have tried multiple ways that I've found on the web, but still, my Turbo 2 has at best 3 to 4 hours of running time. Several months ago, I had the battery changed out. New battery behaved the same way. I'm convinced that Nougat is the culprit here.
Fully charged
Within an hour it went down to 68% and then shut down down. Any other fixes?
Just got a new battery fro the Droid Turbo 2
And it's working as it should. Apparently, the battery installed this past September was faulty.
