Battery status changing up and down at random - Galaxy Tab S Q&A, Help & Troubleshooting

Hi, I've got problem with my battery. It sometimes happens, that my battery status drops e.g. from 50% to 10%, after restart it goes to 25, after restart to recovery mode it shows only 9% and after another restart goes to 25. What to do?
I tried to calibrate my battery, delete battery status, flash another rom, but no result.
I tried let my screen on having a photo presentation and I managed to have screen time on about 10 hours. So it seems that battery is OK, but the dropping of status happens and its annoying.
Somebody has a solution?
Thanks a lot.

What do you mean by battery status? Is it the one that is in settings or status bar? Anyway this might be caused by having certain apps on when you open a lot of apps or high usage apps. It could also be when you installed new apps, they could be running without you knowing also. Or it may be some software issue causing that to happen since it seems your battery is OK.

Sigh. I have this problem too - it's been documented on this forum but I forgot which thread.
The source of the problem is that the mis-calibrated fuel chip. Somehow all recent samsung tablets rely on a faulted algorithm (i won't go into the technical aspects of it) to calculate the remaining battery percentage, and the accuracy of such a calculation degrade over time. The only solutions are 1) use a safe pry tool to open the back cover yourself and reconnect the battery - a risky procedure I won't recommend 2) Send it back to samsung and have them fix it.
All qualcomm chip based tabs/phones don't have this problem - it only happens with samsung chipsets.

Thanks a lot for the answer, however, not a good news...

My Tab S 10.5 sent to repair center because of unable to charge my tab after setting it to charge (battery at 7%)...
I was unable to charge... powering charger won't do anything... Could it be related to this problem ?

I got the tab s ehh about 2 weeks from launch and everything works fine. Could it be the new ones?

Don't know... I got an answer from repair center: tablet rooted, not under warranty...
As this is an hardware problem (I can't power on or charge it) and I can"t even access recovery or download because of no life on my tab :'(
I mailed to customer services with complete explanations on my problem... awaiting their anwser...

How did they know you rooted it?

You win !!!
I don't know... As I can't power on my tab even with power supply I just can suppose that they just plugged my tab to an "automatic robot diagnostic tool" and seen that the Knox fuse was turned 0x1...
This is the only suggestion I can make...

Hello EveryOne,
I have Imate PDA2K and any one who is going to solve my following two issues i will pay him $5 as a gift from me by PayPal.
The problems are:
1. When ever i remove the battery of my phone to change the sim card the time and date changes to the default time and date something like the manufature date. I try to upgrade the rom to wm5, then wm6 but nothing help. Even the backup battery is showing 100% full all the time.
2. When ever i try to call i press the answer button but the call don't connects. Some times connects and some time i have to try hundreds of time to connect my call. Same thing is for the recieving the call. Some time it connects and sometimes it hangs during answering the call.
I will really pay $5 who will help me to sort out these problems. I buy this device as pre-owned device that's why not able to get help at clubimate.com and hence plan to get help here and pay a part of pre-owned fee to someone here.
Thank you,
1.) it's a backup battery problem, change the backup battery.
eventhough it says 100% doesnt mean it's not failing.
the backup battery is charging from your main battery.
it may show 100% but easy recharged when you put the main battery.
if it is easily recharged... it will easily discharge... hence, flat batt.
2.) i dont know this but it maybe related to main battery failing to give power to the phone module. i had a BA with no service /and/ talks disconnection once but when i changed to a new battery it was gone.

Thanx for your response...
1. Can backup battery easily changable i mean is it like a big battery like we have in our pc motherboards or a special service center have to change it?
2. Let me change the baterry today and see what happens.
no prob... just add your reward to your battery procurement.
and i hope that works...
What else may be?

I have changed the battery today and it done the same call answering problem just one time in over 20 calls before this ratio was 99% of 100% times.
What else may be creating this problem of hanging mobile during recieving the call. And also please tell me which rom of wm6 is best you think i will use?
install 2003se rom back, if u hv 2005.
try xplode's latest cook. it's in the WM6 thread of BA
The rom does not matter (well mine is a lil quicker than others but)
1. Simple SIM change procedure - press power, wait 10-20 sec. , then remove the battery and change the sim. after powering on hit reset once (or you will get no radio) - this way the date will not reset
2. Phone LAG - this problem occures when a lot of memory and cpu power is used for the OS, then the phone starts to lag. Here is a simple tweak which will speed up the phone app - press Start => Settings => Sounds & Notifications , remove the check for Events (warnings, system events)
there are a lot of tweaks which will speed up overall performance of the phone, but you need to search the forums for them
And remember, the phone app is the same for all WM5/6 devices so the tweaks are the same, you can look in other devices forums for tweaks
Thnx Every One!
Hello,
Thank you every one for your replies.
I changed the battery and currently checking it to make sure the problems got solve out.

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 had to get a new battery and performed a hard-reset on my phone and all was well after that. make sure you have a back-up on your numbers....
well savain
thanks for ur reply.....
did u have the same kind of prob like the over voltage???

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?

[Q] Battery Charging Issue.. very werid.

There have been similar threads before... but my case is kinda different. :c
Problems started a couple days ago. Using the AOKP M3 rom, on the lockscreen, it says the phone is charging. However it is not plugged in... so i rebooted. Still there.
Then i went ahead and cleared battery stats and cache. Still there. I started to every combination of CWM tools to attempt to fix the problem. Still no luck. Says charging... Then i realized that maybe its the software side. (Being very optimistic that it isnt a hardware issue) So i check the About Phone setting in the Settings.
It says Discharging which i thought meant "ok its the rom" so i went ahead and flashed Andriod HD revoultion. Still charging on lockscreen and battery icon...
Anyone know anything about a fix? or something i really dont want to send it in.......... although i guess i can live without my phone for a week or so.
Any solutions tho?
Note: Lockscreen says Charging. Battery Icon is Charging icon. About Phone is Discharging and the Battery graph is at 1s on Battery forever :c
EDIT: the Battery setting now says Discharging. It is only the lockscreen and icon at this point.

You got hit with this:
http://code.google.com/p/android/issues/detail?id=23789
It's pretty damn common I'd say (my phone had it and I exchanged it), so either replace the USB board yourself (as people on that site confirmed it works) or send it in for repairs. There's nothing else you can do unfortunately.
Sucks that such a bug exist without any real communication from Samsung or Google.

[Q] Battery History problem

Hi everyone, I'm recently owner of a Galaxy Nexus...and I'm having some troubles with battery/usb, and battery status...I've already look at the threads about usb problems...but, what I didn't found is this:
My battery history is not right...It didn't show me the apps consumption...or it shows it, but like freezed in time...The time of use its freezed too...It acts really strange. I did factory reset...but nothing...I'm totally stock.
Any idea?
Besides, when I plug the charger, it takes about 30 sec to show the bolt icon on notification's battery icon.
The Battery/App Stats aren't displayed in real-time, you would have to manually refresh them to see the updated data.
Are you using an official Samsung battery?
It could be the charger you are using, I've actually been able to drain my battery when it's plugged into a live charger. Anything below 1 Amp output seems to delay the charging process significantly.

Yes, official battery and charger...I press on refresh but nothing happens...so I've tried to plug/unplug severaltimes..sometimes at PC's usb, and the history did reset...but when I think its working, I press on refresh and nothing....It keeps showing 3 secs of battery usage for example
I would suggest rooting (if you're not already) and attempting to wipe the battery stats manually. There could be something stuck in that file that is preventing it from updating when required to.
With a root file explorer, go to Data/System and remove "batterystats".
Other than that, I'm stumped. I've flashed hundreds of ROMs, and wiped my phone hundreds more times and I've never come across this issue. I'm using the Toro variant but I doubt that has anything to do with it.
Let me know if that worked though, I'll keep looking around for a solution.

@Liskrig thanks for your help...I finally change it for another nexus, this one works properly. :highfive:.
I think it was all related to micro usb issues...

Battery Level stuck @80%?

I can not seem to clear my Issue of the battery always showing 80%.
I have reflashed back to Stock, but still the same problem.
Even when I had TWRP recovery installed it showed as 80%.
Any ideas how to fix this please?
you have infinite battery, be happy!
I wish
Fixed it by flashing Open EU H815.kdz file once again and now the battery use is showing correctly.
Edit: The problem is back again!!!!
After several hours when it seemed okay, I put the phone back on charge and Bingo.
Stuck back at 80% again, even on my other original LG Battery, and to top it all i have a stuck LED on faint green.
WTF???
I had the same problem before, how many apps do you have installed? Does it charge in safe mode? If not, does it charge to 100% when the phone is powered off?
Tried Safe Mode and the same problem persists.
The battery seems to charge fully but the OS is not showing it correctly
Hmm, in my case, it was always stuck at 74%/75% and it doesn't charge more regardless what the indicator says. What about if you powered off the phone and charge, does it actually go past 80% and to 100%? I fixed my problem as I had 739 apps installed incuding system apps so I greenified everything except for those I needed and that fixed the problem, not only am I getting more than 2 hours of battery life regardless if the screen was on or not, it's now 12 hours or so of battery life with a few hours of screen time but the charging is fixed. Before I used to also have problems installing in Google Play Store, it would actually sit there doing nothing after the download and install when it feels like it even after a hour or it can install fast.
Tried charging while turned off and still gives the same reading.
Last night I reset the phone and left the battery out for 30 mins before re-inserting and setting up the phone once again.
So far it seems to be fixed and showing correct battery %.

Sure, see attached.... Please note that I am including the system apps in the app count as this is what's reported by Titanium Backup *root. I was wrong, I seem to still be getting the stuck battery percentage indicator which can happen at 73/74% or even 97%.
It seems the stuck battery charging % problem came back when I changed the brightness to 100% Auto but went away when I changed it to 0% Auto. I had the problem at 38% Auto too.
Is there any workaround? I just flashed my LG G4 from 10a to 10e and Rooted it. And It happened exact the same.
After a reboot I didn't have Service IMEI Null . This happened twice in a row, after that it magically resolved and now I have Service and IMEI... But after some reboots I started noticing that LED green turned on and the 80% Stuck Battery....
Im experiencing the same issue battery stuck at 80% and green led stuck on. Issue went away however battery life was appallingly bad, went from 1.5 days battery life to struggling to last a day. Battery stuck at 80% has come back today.
I have tried factory reset, upgrading from 10c to 10e.
i'm having the same problem: battery level stuck at 80%, network set to 3G but not actually connecting, and the inability to charge the battery when it is in the phone - even though it says "charging" the percentage kept dropping (tried different chargers, cables, batteries, and even wireless charger - i can only charge using a separate charger). the battery not charging started about a week ago. the 80%/3G issue started this morning.
no root or any other mods, very few apps installed. i've had the phone about 6 months. verizon. 13B. 5.1.
i did wake up the other day to a frozen "firmware update" screen, but it has not come back, and i've checked for updates (to 6.0 maybe) with no success. this "firmware" screen was after the battery stopped charging, but before the 80% problem. i had to pull the battery after it sat there a few hours (it said "don't disconnect USB" even though USB was never connected, and there was a progress bar at 0%).
UPDATE: this thing may be falling apart in front of my eyes. now my service is disabled and I have no network connection showing up at all.

Try taking the SD card out, if that doesn't work take the sim card out and then back in. That normally gets the service working again for me.
I had this same issue and sent it back to the supplier, they than forwarded it onto LG who couldn't find any issue with it. Im now waiting for it to be sent back to me.
Are you using a 3rd party (non-OEM) battery by any chance? I ask because I had the same issue occasionally when using a non-LG battery. It would fix itself after a few reboots or by installing the LG battery that came with the phone. I truly believe based on my experience, and others (there is another thread related to this exact problem) that the issue is purely battery related. Even the service disabled symptom.

I don't have a 3rd party battery so I don't think that's my issue
OEM battery for me. I did remove SD card, and reseated the SIM: no help.
This is my current work around: Turn off phone. Charge battery to 100% with phone off (overnight). Turn phone on.
It seems to charge fine (and have accurate %) when the phone is off. Then it powers up with accurate battery percentage and 4G coverage. Note, I've only tried this twice, but it worked both times.
I'm having the same issue. Battery stuck at 80% and green constant notification light. Not rooted BTW.
I assume LG will investigate the issue while I am stuck with no phone for weeks.
I should have never bought a non nexus phone...
