[Q] Inaccurate battery reading - Samsung Galaxy Nexus

Hi,
I am having issues with the remaining battery % being displayed:
1. If I power my phone off & on again, the battery % drops drastically e.g. 60% prior to power off, then 15% when its powered back on. The battery % will then increase over the next hour or so.
2. Yesterday my battery reached 0% and auto shutdown. I plugged into charger, immediately powered the phone on & it was then displaying 49%. I then unplugged from the charger and the battery gradually reduced from 49% over the usual timeframe.
I am running latest ZMOD & LuckyK kernel, but this error has occurred with other ROMs including stock.
Any ideas of how to fix?
Thank you

[Q] Severe Battery issue with galaxy SIII.

I am facing a severe issue with the battery of my samsung galaxy SIII which i have purchased in june-12.
Sometime battery of my phone is charged very quickly( max 1 hour) & then it will discharge very quickly(max 2 hours) too. Battery will completely discharge from 100% to 0%(in 2-3 hours).
This problem occurs once in 10 time.
I have observed, When my phone battery start charging very fast, from 10% to 85% in just 20-30 minutes.
i disconnect the charger, Restart the phone & it is showing only 12% battery remaining.
It means phone was not charging just the battery percentage is going up.
this problem comes to me at least once in week. and i have to charge my phone 4 times a day.
Normally, I can use my phone battery for full day once fully charged.
So, it doesn't seems to be a battery issue.
Please have a look in the issue & guide me how to proceed.

Battery Issue

Has anyone else recently started to have battery issues? Im using the stock battery, phone and battery is about 4 months old, the battery percentage once it hits about 45 to 55 % will start to rapidly drain, if I reboot the phone during that time the phone will reboot and the battery now reads 0%, then will continually boot loop till I plug it in??????//

Problems with battery

Hi, I picked up my phone from repair shop a week ago and since then when my battery goes below 55% i get message that battery is 0% and phone is shutting down, and then I put it on charger and sometimes it starts recharging from 1% but sometimes from 55% and if i charge it to 60% it works normally, but when i charge it to 100% it turns off on 55%, can someone help me please is it problem in software or maybe it is problem in battery?

It sounds very much like this:

I replaced the battery and it's been working well for a few months now.
Battery drop from 50 % to 0 %
I had the same issue.
After force shut down (power + vol-up for 10 sec), the battery went back to normal.

EDIT :
That was a short lifesaver, battery is "fubar".
Guys , maybe there's something wrong with the battery charging in Amami . I have two Z1C, one of which normally charge up to 100 %. But the other charges the battery to 100% only in Stock 4.4.4 ... In all versions of Lollipop (stock or not) battery charges to 82% ... Calibration of the battery does not help. I replaced the battery - no change. I tried another powerful charger by Samsung - without effect. Anybody have an idea what's going on ?

Galaxy tab 3 8.0 battery issue

Hi,
Bit long story, I know, but I'll have rooted Galaxy tab 3 8.0 and the problem for few weeks has been that the battery has gone mad.
So, when battery dies and tablet shutdown and I try to start again after a while there's no enough juice to even start fully or if it starts it shows 1% and shutdown immediately. That's as it should be I guess.
BUT, if I plug into charger when batt is empty and it has shutdown it suddenly shows very random percentages like 12%, 45%, 52%. 75% etc totally random even it should be something like 0%-1%.
If I then fully start it android shows that same big percentage but batt won't last a minute if I plug off the charging cord.
If I then plug in the charger again when it has shutdown it may show totally different percentage than last time but also dies as soon as I plug off the charger.
First time it could be like 12% but immediately after shutdown suddenly 71% etc.
Also when I try to fully charge battery it often jumps from around 70%-80% to 100% and while discharging it can suddenly drop from around 45% to 1%.
I have tried many things like wiping batt stats and fully charge from empty to full with power off/on, restart after full and charge again, leaved it screen on to slowly kill the batt etc.
So is that batt just badly worn after many years or is that "battery information file etc" somehow messed up that it can still be fixed/calibrated?
Ouh, and my current rom is AICP 12.1 (Nougat 7.1.1) if it matters.
Thanks

Big battery drain from last night

Hello.I have htc 10 from year and 4months.Never had a problems with the battery before.Usually i charge it to 100% before i go to sleep and in the night without using the phone have 93-94% in the morning when i wake up.But this morning i woke up and saw 25% 75% battery drain without using.Every time after when i using phone i delete all of the recently apps.Before 35min i charge the phone do 100% again and after 35min without even touch the phone i have 93%.I checked the apps that drain most and its this - System - 6%, Mobile networkk 2% and Phone idle - 1% and everything other 0%.
I never let down the battery to 0% to turn of the phone.Maximum 5 times my battery was lower than 15% and never used Power saver modes.Always with the last official software.Can this be a problem of the battery and can the warranty fix that battery issue ?
I tried the fix from this theme but dont see any improvment.Also i noticed that when the phone is on the charger, the phone says - "16min to full charge".I leave the phone and after 10min i look onto it and it - "14min to full charge". After another 10min - "12min to full charge."
