[Q] Battery issue. - Samsung Galaxy Core

I have a strange battery issue in my phone. My phone switches off at 5% or sometimes even at 12%. When I restart, It shows 0%. Anyone else also facing similar problem?
Anyone with a solution?

Hell yea!! Even i have the same problem... It goes off at 5% and restarts with 0% battery remaining....
Maybe v should both try a battery calibrating app from play store..

It is completely normal to happen. Depending on the surrounding the phone is kept in it switches off automatically to conserve battery drain, so it can happen anytime when phone reaches low battery or critical state. It is the device's method to prevent battery drain as a draining battery can completely destroy the battery and the mobile, so dont worry make sure power saving is on and keep your phone charging

Yes!
The level at which the phone will get off depends on how you are using and your nearby surroundings, if its too hot or too cold it will go off soon, also if you are using net and gps or any other battery consuming operation it will be off sooner than you think, I am too on stock and sometimes it does happens and sometimes not....
PS when you switch on your phone, it consumes some % of battery just like it happens when you start a car so it will go down a little bit.

Oh! I see!! Thanks for d info....

Thanks mate. That was really informative.

[Q] Huge Battery Drain on Reboot

Hello Folks,
I m facing a wierd prob on my device from last 3 days and its about my battery. its not about how frequently my battery is Draining. When i charged my Mobile fully to 100% and Reboot the device , after reboot the Battery comes to 93%. same when my device was on 35% and after reboot it came down to 3% WTF.
I thought its battery callibaration prob. i was on DDLF2 when this prob occured so i made Full Flash using XXKPE--> XXKPQ. But still prob Persisted. Then i used a app Called Battery Callibration From market By "Nema" and follow the Procedures as mentioned by app to callibrate my battery. bt still the prob persist.
one more thing , after doing 100% charge the app showed battery has 4185 mV of charge and After the reboot the perc. came down to 93% then app showed the battery still had 4122 mV but with 93%.
im currently on Stock XXKPQ
I'm having this problem aswell. Don't you worry, its quite offten appear after flashing. Use your phone as usual ant and your battery stats get normal after couple weeks. Don't do any calibrations, android does it by himself.

Thanks mate , i will try it and post feedback after a week
Charge to 100%, drain to 5-10%, charge to 100%. Repeat a few times. This is battery calibration, the app does not work.
I feel battery calibration is most rediculous method that android users have to do. A dumb nokia 3310 can show us accurate battery indicator even if we reboot it 100 times.
Google developers really have to concentrate on this battery part.

Yes that's what I'm saying...
i too have the same problem ...
I also have the same problem
If you use your device with no flashing whatsoever, it will always show right battery stats, you can't flash your damn nokia 3310
I too have the same problem.Looking for a remedy.

Same here but there has to be some solution. May be our collective intelligence will find some good solution and help others too
Same same!

It is normal for a newly flashed ROM. I always had 20% drain after reboot after new flashes. It's normal if:
1. Newly flashed rom - let the android calibrates itself.
2. Fully charged battery which was left attached to the power source for sometime. Battery discharges itself quietly despite it showing 100%.

Probably you need a new battery...there's a limit to how many charges...happened to me, my battery was no more than 12 months old...try this..charge with the phone on till 100%, then shut down the phone, charge with phone off till 100%..switch on the phone and if you do not get 100%, repeat the process until you have 100%...
me too, when my phone fully recharge (showing 100%),I reboot it. after I reboot it shows 92%

[Q] Sudden battery drop in official jb leak

Hi..
I know this is a known bug in jb leak 1, but is there a fix for the sudden drop in battery level?
Daily as soon as the battery level reaches 30, there's a drop of 10%.
I already tried clearing battery stats from recovery but still no luck..

Like you said, it's a known bug. Even the custom 4.1.2 ROMs like MagicMod and CM10 have a similar issue. With those two the battery reading will go from 19% to 1% really quick but stay at 1% for over an hour sometimes. It's not a problem with the battery, it's just the way those ROMs report the battery reading (that's part of the reason why clearing battery stats doesn't help). AFAIK there was never a fix for that.
Brought to you by time and relative dimensions in space.
Happens with me too using dirty unicorn with jbx. As soon as I get to around 30% it just drops to 19

I have a wierd problem. Im on jb leak 3, As I recharge my battery, as it reaches 100% it suddenly drops down to 99% when I disconnect my phone from the charger. Any solution is deeply appreciated. Thank you

There is no solution for that I'm afraid as the same thing happens on custom roms and stock with the 1% battery feature. It's been happening for a long time so it's nothing new.

Samsung chargers I believe have more voltage supplied during charging. That's why it charges up quickly. While laptop doesn't give out that much of voltage.
I once have battery drop but only around 5%.. 24%-19%.. but now it seems fine.. I use leak 3 as daily drive.. I think it depends on charge cycle.. if u charged a lot and your phone are used to the pattern then your battery cycle won't be messy with sudden drop..

Facing weird problems with battery

Hi.
If I am on KitKat, and my battery level goes below 20%, my phone switches off and I cannot start it unless I charge it a little.
The same happens on lollipop but instead of below 20% it's shuts down as soon as the battery hits 10%.
Is there something wrong with the battery stats? How do I fix it? Or is something wrong with the battery itself?

It's nice to know that I'm not the only one. Also I'm experiencing slow dows which is making me crazy and I don't know what is causing the problem.
Something wrong with our battery stats?
My One shuts down when it reached 0% battery.
i had same problem let the phone die and left it on charge overnight problem now gone

But normally it shouldn't shut down at 20%...
I will be calibrating my battery today. Let's see.
A simple calliberation solved the issue. Thanks a lot everyone! Cheers

Why my phone doesnt charge??

This is my 3rd replacement from fk but still same problem, the phone doesnt charge when kept in charging with somewhat battery left, but charges properly when the battery goes null.
Observe the attached screenshot carefully, the phone suddenly goes awake and starts discharging battery instead of charging...plz try keeping phone to charge when battery is below 20%
Could be a software bug. What firmware are you on?
How much does it charge while the phone is switched off?

Yes its surely a software bug bcoz sometimes it happens and whenever i drain battery completely then this issue never occured. And when some battery left the phone disconnects from charging at 50% and in device information also it shows dischargimg
First thing I did was update the OS when I got the phone. Your problem never occurred to me. Have you tried searching for a software update?
And what firmware are you on bro?

Problem with my phone battery ...

HI GUYS
I have a problem with my S Duos 2 battery
It's never can be charged up to 80 % and when I use the phone it turned off in 30% and if I try to turn it on he said that the battery is 3% , I tried to change the battery and it the same so can someone tell me if the problem in the software or the hardware
....
fix
i think you should try battery calibration this will help you to change you rom's battery stats and it will re calibrate you battery
hope this will work
1-charge you phone to 100%
2-open batter calibration
3-click on battery calibration(you will see calibration successfull)
4-uplug your charger

done

I have an after market battery with the same issue. I have been conditioning the battery by charging to full an draining completely while running those calibration apps. Seems to be getting better.
