[Q] Main battery low: 0% for 36 hours already

My Palm Pro has a very strange problem at the moment.
The battery indicator states it's at 0% and I need to recharge the battery. The (not so) funny part is that it's giving me this message for the last 36 hours!
Things I've done so far:
- I've done a hard reset
- Pulled out the battery for 12 hours
What I will try:
- Put it on a charger instead of the Mirco USB Cable
Never read about a certain issue. So I thought I might as well post it on XDA
Fixed myself. Completely drained the battery and recharged it using the original charger.
Device is working with no problems at all for the last two days

Battery level wrong

My device is N9005 with stock rom and Towelrooted.
Yesterday night my battery was at 48% so I charged it overnight. I got the notification that charging started. This morning I unplugged the charger, and when I picked up the phone about 1 hour later, I noticed that the battery level was at 86%, which is strange since it has only been on standby.
I checked battery usage and it shows 1 day and 14 hour on battery. this correspondents with the time I plugged in the charger last night.
I plugged in the charger again and notice that it start charging. In battery settings it shows 'charging' but it doesn't reset the timer instead the timer keeps running. The battery level also doesn't increase.
I have switched chargers, cleared cache and rebooted several times already, but no change.
I installed battery calibration, and the app shows that the battery level indeed increase, it went from 3800 mV to 4012 mV in about 30 minutes, but the percentage also doesn't increase and is identical to the stock battery indicator.
Is this a known bug or where should I look at my problem?
A reset would the medicine for your problem backup with titanium and go for it
Sent from my SM-N9005 using XDA Free mobile app
Been there done that. Flashed the firmware again, same result.
Phone is at the service center now, so will know more in afternoon.

factory reset does phone damage ?????

hey i worried about the factory resets phone to do much more than 8times per week. i dont ever to do resets than lower battery 20℅... after last reset battery discharge 3 hours 10℅. before last reset not drain quickly just 2% per 8hours without battery saver. i did when the phone is turn off when 0 battery i put on charger and see 0 battery so i power device. is it bad ??? i want my old battery status.. or maybe i waiting for battery calculating time ? because not show how many hours left to discharge.

Battery regarding help!!

When I charge my phone till a % for example 54% and then I disconnect the charger and use the phone, the phone's battery indicator shows 54% for 20-25 minutes and then it will go to 53,52,.... and so on. Tried calibrating but it can't fix.
I am on Stock ROM 8.1.0 and also if my battery is at 36% and I use it for 5-6 minutes and I think that now it should show 35% but it doesn't show but when I press lock button, then the battery indicator shows 35% immediately. It means that battery % updates more quickly by press lock button rather than while normal usage. I don't know whats the actual problem. Battery is fine, it gives 5-6hrs SOT. Please provide me a solution. ?

battery issue

my phone old batter were drop suddenly it's charge from random amount
for example from 35% to 4%
or from 20% to 1%
any way i changed it with new battery
the new batter were at 60% so it lasted for almost day
then it drop from like 20% to 3% and it remained on 3% for like and hour or hour and half
i left it till phone shutdown and plugged charger while phone off
it charged for tow hours to 60%
then left it for 15 minutes and found it become 100% which is strange
now i've been using it for 14 minutes and still showing 100% for battery
how ti fix this and make phone calibrate the battery to show the right charge amount
i tried some apps but nothing seem to fix it

how to check that?
as you can see battery consumption isn't accurate
it remain at same level for too long then suddenly drop to low percentage
and this battery is new
what cause that?
