[Q] whats happening to the battery indictator?

I am running IC 3.3.9 on my Sensation.
Today in evening i noticed my phone was getting laggy and stuttering alot so i thought I shud reboot it. it was 32% battery left. after reboot it was 8%.. how did that drastic change occur after a single reboot?
Then i kept it on charge as it was falling rapidly and after 2 mins i got a message that your Phone is consuming more power than what is supplied... its not exact quote but something like that.
I kept it on charge for 10 mins turning everything off... the phone was laggy again and battery showed 10%, so i rebooted again while it was plugged to charger..When it reboots, the battery indicator showed 62%... how could it change from 10% to 62% in one reboot???
When i dont reboots it falls down at constant rate except at 100% it stays for a longer time and then suddenly falls to 80%..
Damn, can someone fix this indicator issue or tell me a solution? What is causing this problem?
I deleted battery stats once i flashed it about 2 days back and i thought it would return to normal after some cycles but tis getting worst
EDIT: Just to add: I am on Stock Kernel
1( How are you running IC? EDIT: Oh stupid me pff
2( it might be a bug, nothing serious. What you can do to make sure it is a bug, is to just make one of those magically battery drain happen again, and let it drain.
He is running Insert Coin not icecream sandwitch... I have similar problem ...

Z3 Dual battery levels jumps arround..

Hello everyone,
I've bought an used Z3 dual couple days ago,and after having it for some days now I noticed that the battery jumps around,for example from 88% to 50% then 32% then goes back to 88%..
That usually happens when I'm running heavy apps,like camera which caused a phone overheating as far as I noticed.
Anyways,Yestrday I fully charged the phone and when I plug it from the charger it does down to 50%,it stayed at that level for almost 24hours.Few hours ago the phone suddenly the phone turn off (while the battery was still 50%).But After putting the phone in the charger,the phone keep showing "charging icon" and turning off.It was like this for 30min and it is not charging at all..
Have anyone been in the same situation before ? What could be the problem ? and how would I solve it ?
Waiting your kind replies..
That sounds like the phone battery is literally dying.
Don't think that it is a software problem you could solve on your own.
You could try this though, doesn't hurt if you do the Method 1:

galaxy j7 battery problem

i think my phone has some serious problems and i'm wondering if it's the battery dying or a short circuit
when i plug it on a charger while of it shows a normal charging image but how it switches from one animation to the other so i can see the status of battery percent it's like a short on the screen happened
it chargers to 100 but when i switch it on it shows mybe 95 but never 100 and if i connect it to a charger to get to 100 it only decreases
it gets warm now days which did not happen and it like drains 50% overnight which is obviously not normal. these two days the battery life is like 4 hours with internet wich with j7's battery it should not happen. if i switch it off and then on again i loose like 20% of battery and if that is all i had i get 0% and the phone doesnt switch on. the phone never had contact with water . it's been 4 days since this started and it happened all of sudden like today my phone stays up to two days at most and i just woke up it barely finishes a day without data and with power saving mode
i'm sure it's not about background apps or any activities because i hard reset it already and i don't have any app. and it's not about wifi or sync or poor network i tried all that. i did everything it didnt help. i could buy a new battery but i'm scared it might be a short because i don't think a battery can just die in one night like this.
can anyone help me with this or it's nothing serious and i have to change the battery

Galaxy Fold Z2 battery dropping to zero from 50%

Hey fourm, sorry for the long read but if anyone is technically savvy with batteries or voltages/electrical components please read! this might not be specific to a Fold but any device may suffer from what my device is suffering from.
I have recently had issues with my Galaxy Fold Z2 and it unexpectedly dropping to 0% charge, the first time this happened yesterday i was in an application and was switching from the larger display into the smaller one, upon closing the display the phone shut down and i wasn't able to get anylife out of the phone except a vibration when holding the power button, but nothing on the screen. I had about 35% battery at the time but all of a sudden it was at 0, after putting it on the charger it spring back into life. Today however i experienced an even worse problem... My battery was around 55% and i was connecting my phone to my cars bluetooth and importing contacts to the cars console, suddenly the battery went from 55% down to 9% instantly! i was shocked and took a screenshot of the battery graph showing its gradual decline from 100% to 55% but not to 9% to highlight the sudden drop, the battery status on the top of the notification bar was showing 9% all of a sudden but the graph wasnt just to actually see the drop! after that drop in battery it only took about a 30 seconds for that 9% of battery to jump down to 1% again in an instant fashion, following this only a few seconds later it shut down.I was thinking it could just be a dodgy battery for whatever reason but after trying to charge my phone after this sudden crash from 55%-9%-Flat i was unable to charge it up. The phone would signify that it was charging but not giving me a percentage, it would show the charging animation (the animation you get when phone is off and charging) but would only last for around 3-5 seconds before shutting off again and showing the charging icon again, and then shutting off again and rinse and repeat on a loop without charging but attempting too and resetting every few seconds! So for about an hour i couldnt get it to boot/charger properly and i almost gave up, but i decided to try a different charger, i was using the 25w supplied charger but i switched to a 15w older one and the phone ran the charge animation again however this time it identified the battery was charged at 55% rather that it not showing any charge level and resetting and trying again as it did before, this time it went right to 55% and from here the phone booted up and is working normally again!
Im really not sure whats wrong, im starting a process to send the phone back but i really wish to know whats wrong with my device! if anyone has any clue to this strange behaviour please let me know!
