Reboot when battery below 50% + heavy load - Galaxy Tab S2 Q&A, Help & Troubleshooting

Is there a way to re-calibrate the battery ?
Since my T719Y always reboot when I do heavy load (gaming,etc) and the battery is below 50%.
(low load;watching youtube is fine)
No problem occurs if I plug in the charger.

Unplug and Replug the battery?
The tab pro needed this and it worked as normal afterwards.
I think i drained the battery beforehand

Help! Battery won't charge past 70%

I didn't notice this problem until the day before. My battery status is displaying 70% when the phone consider it to be fully charged.
I've drain it to 5% before charging overnight, but the status still display 70%.
I am not sure if this is a problem with my phone or the battery. Any help would be nice.
Try this but you need a rooted phone for it: http://forum.xda-developers.com/showthread.php?t=722862
it is just a status bar bug
the battery is probably fine
use Gauge Battery Widget instead to see the real stuff

Thank you for the link!! I am trying that now.
This is not the status bar problem as I've test out some of the widget.
The phone would only charge up to 70% no matter how long it will remain on the charge.
Going into the battery info in setting also indicated it is at 70%.
At this moment I am draining my phone with max brightness and everything turn on.
Start off at 70% at 9:30am and now (2:00pm) is at 3%
So I guess I should try to charge it full with the phone off
Did you recently flash firmware to your phone? Make sure your battery is fully charged whenever you flash firmware because it will clear the battery data. It seems to me all you need is a battery calibration. There is a procedure posted somewhere. IIRC, you need charg up the battery to 100%, power down, charge 100%, power up again and repeat a few times.
I had the same problem.
After a day of charging the battery fully charged notification appears. As soon as I unplug it the battery immediatly jumps to 70%.
Is there a way to fix this? Perhaps reflashing when the phone is fully charged (which is currently 70%).
I tried the rm /system/data/batterystats.bin but did not remedy this problem.
Same problem here. It has been this way for a month. Tried calibration, different batteries, different ROMS....everything.
who can help?
using alternative battery widget is not an option if battery stats from settings also displays 70% max
this is very unusual problem - i would suggest:
1) install https://market.android.com/details?id=com.nema.batterycalibration (phone needs root)
2) drain battery to 0%
3) take out battery for 5-7 minutes
4) put it back and turn on and drain again
5) repeat untill phone will not turn on
6) while still off charge phone to 100%
7) disconnect charger power on the phone, let it boot and use the battery calibration app
8) now let the phone discharge with normal usage untill it powers off (do not reboot, power off during discharge)
9) put the phone to charger, turn it on and let it charge to 100% wo reboots/poweroffs
should be fine
let me try tomorrow..I have similar issue..
Sent from my GT-I9000 using XDA App
Today, over night charge from 70% to 79%
have you followed my tutorial from this post -> LINK
also can you dial *#*#4636#*#* pick battery information and make a screenshot, then another after a minute or two ...
I made this thread over in the captivate forums, it explains the issues in detail

What rom/kernal are you guys using?...
Sent from my MB860 using xda premium
concentrate on points 2 to 5 of my 'tutorial' and for god sake use only original charger
and yes, what kernel
Hey Somator, I am trying your tutorial now. I drained my battery to 0% on my phone. I then would boot it up, it would register 1%, then turn off.
I then put my battery in a coworkers phone today and it read 40% when it previously read 0% on mine. So I depleted the battery on his phone, reinserted it into mine, and I am now currently charging it to 100% while it is off. I will let you know how the rest turns out.
I have tried calibration procedures on stock rom, MIUI, CM7, I9000, and I897 Roms.
drain the battery on his if you can and then charge on yours
after that wipe battery stats with https://market.android.com/details?id=com.nema.batterycalibration
//edit: oh you did exact that - well should be fine from now - still wierd why it just 'decalibrated' by so much in the first place
the original charge has helped me, everything is fine
In case someone is looking for an answer here (considering this is the thread that comes at the top of Google's search results), this is what worked for me:
1. Take the battery out.
2. Plug phone into wall charger.
3. Put the battery back in the phone.
4. Let it charge for an hour. Mine said 5% the entire time it was plugged.
5. Remove phone from charge. Remove battery. Put them all together again.
I hope this works for others.

[Q] Tegrak 100% battery charge?

Hey all,
Noob question. I recently went to JVP (doc kitchen) and tried out multiple kernels (speedmod, fugu, tegrak). I only noticed this issue after going to tegrak's kernel so suspect it's kernel related.
The issue I'm having/suspect is that after "100% charge" the battery would start to be consumed (even if it is plugged in). This is most noticeable if I'm at my desk at work all day (phone on charge) or when I leave my phone charging overnight. When I disconnect to go home/go to work, I can see the battery is at 85% or similar (as if the phone wasn't on charge). If I was to disconnect it as soon as it hit "100%" it'll be at 96/97/98% as expected.
I'm not an expert and logcat confuses the heck out of me to be honest, but would anyone know what strings I can search for to determine if the phone "stops charging" when it hits 100%? I'd prefer it to be on a trickle charge (ie keep the battery at 96/97/98%) so that when I disconnect, I have a near full battery.
Is this a kernel issue? or a battery level calibration issue?
TIA

Please do this procedure and see... once u finish ur 2 or 3 cycle u'll get the result...
- Charge your battery full, bump charge to get the highest level possible ; note that it's not a big deal if it shows 97% when you unplug after bump-charging
- Drain your battery to 0% until it shuts down by itself (without plugging the charger or connecting the phone to a pc)
- Wait 2 minutes and reboot the phone to ensure the battery is completely flat (it might reboot fully, half way, not at all, don't worry) until it dies again
- Remove the battery and wait 2 minutes
- Replace the battery and plug the charger without switching the phone on until it shows 100%
- When phone shows 100%, boot in recovery (volume up + home + power) and go to > Advanced > Wipe Battery Stats > Confirm (move up/down using the volume keys)
- Reboot the phone and unplug the charger when the "battery full notification" comes (wait for the notification before you unplug the charger)
- Now use your phone until the battery is flat again and charge full (no need to have it turned off, unless you it to charge faster). Repeat 2 or 3 times and your battery will be calibrated
- Only wipe battery stats once, run a few cycles of full charge / discharge and after that just use your phone as normal (i.e. no need to deplete / charge fully anymore).

[Q] Help sgs strange battery beahvior

Hi .
I flashed stock JVQ with chainfire 3.7 kernel.
My battery charge very very slowly ( 6 hours to full).
Yesterday I left the phone switched on on charger this morning the phone was off and the battery was on half in charging!
I can't understand what's happening!
Any idea?
Andrea
Try this
Battery not properly charging (possible solution – recommended every ~30 charges, or when the battery won't hold charge)
Phone POWER ON (Enter PIN) – charge to 100%
Disconnect charger
Phone POWER OFF
Connect charger – charge to 100%
Disconnect charger
Phone POWER ON – Enter PIN and wait until idle
Phone POWER OFF
Connect charger – charge to 100%
Disconnect charger
Phone POWER ON
Or maybe your battery is broken and you need a new one...
What u can do is an factory reset
ore you can wipe your batt statts in cwm . (do this when your battery is fully charged
There are several possibilities.
*Your battery Calibration ran off after you flashed. Re-calibrate your battery.
*Note that ROMs or Kernels may cause this to happen.
*Your battery could be faulty and further usage would cause damage to your phone. (If your phone/battery heats up intensively during charging, check it out)
This possibilities are arranged by the most likeliness of what seems to be your issue. If battery calibration does not solve your issue, proceed to checking on your ROM/Kernel. And so on.
Thank you all.
I changed wiped everithing , changed rom and kernel and this morning same problem.
I am going to recalibrate another time , after that I am thinking of buying a new battery.
Thank you guys

Samsung Galaxy S3 Sudden discharge (No battery drain issue)

Hi!
I'm having a problem whith a friend's S3 which I'm not being able to solve.
When the phone is not connected to the charger the battery lasts less than a few minutes being overly optimist.
He bought a new battery, and exactly the same happens.
If I try to charge it when it's turned off, the charging indicator flips between 100% and whatever number between 10 and 100%. So it goes like 100% - 30% - 100% - 31% - 100% - 32% . When it seems charged, I unplug it, try to turn it on, and WHEN IT DOES TURN ON, almost instantly the message "Battery low, connect charger" appears. Sometimes I can't turn it on if it's not connected to the charger.
I've tried rooting the phone, flashing an updated recovery which let me wipe the battery stats, but it didn't work.
Whith the phone rooted I tried whith some play store "Battery doctor apps", same results.
I can't seem to find the problem, any help would be really appreciated!
I have to add that I measured the battery charge with a multimeter and it reads 2.77V out of 3.8 , meaning it's 73% charged.
The phone won't turn on unless I connect it to the charger.

Question Battery Charging problem after recent update

I recently updated my phone to CPH2173_11_C.48 (April 2022 Security).
When the phone is on the fast charging shows but the battery % does not increase, in fact the battery drains when used.
The only way I can get it to charge is by first connecting the charger and then turning off the phone. After it starts charging (and the charging % increases), I can then turn the phone on and it charges properly even whilst using the phone to watch videos.
The only thing I have done recently is to update to the latest firmware.
Any ideas what the issue may be?
If you do the above process then unplug and plug straight back in, does the problem replicate?
Does it only happen below or above a certain battery%?
It happens on low and high battery %. If I unplug and then plug straight back the problem replicates
Noticed something a bit weird, I connected the phone to my PC and it is charging slowly (normal charge, not fast charge). When plugged into an outlet, it shows fast charging but the % does not go up (unless the phone is off).
Could this be a software issue with fast charging? Any way to fix other than to try factory reset?

The culprit looks to be fast charge at lower battery %. I can slow charge at lower battery with the phone on and fast charge at higher % ( around70% +). Whilst off, fast charge works at any % battery.
Could this be software or hardware issue. Problem persists even after factory reset.
