[Q] Weird battery indicator behavior while charging?

I've notice a pretty weird behavior of the battery indicator (precents) while the device on charge, few checks - not permanent, though not serious but intriguing.
I'm using the original charger (1.2A UK with EU adapter) with original usb, Stock 4.2.2 no root or anything else. (The device is 1month old, bought from Play UK)
Also I only could check this with GSam Battery Monitor because its have a history chart so I could check the battery percentage at any given time.
On the app there is 'Chart' menu in this menu there is also option to view 'Power vs Precent Chart' what gives you a deep look into the charging/discharging details (Hour/Voltage/Precents/...).
In several cycles of discharging/charging I've notice a strange behavior of the battery indicator (the precentage) while the device on charge, for example - when the indicator went to 82 it goes up to 83 then goes down to 82, then 83 again, 84, 83, 84, 85, ....93, 100.
In other case - while it was on 81 its up to 82 down to 81 up to 82 and continue regular....
I've found that GSam not showing 29% and 58% so no worry about jumps on these precentages.
Another one: 91, 90, 91, 90, 91, 92, 91, 92, and continue regular.... heres a picture for this session:

Marked in red.
I can confirm that the device's screen was off, no activity or any heat (the battery temperature was cold - also another thing you could check with GSam) at the moment of the 'jumping precentage'.
I want to say that I have no problem with the battery, its working great, just bother about this jumpings...I thought its only on GSam app but when I looked at the stock battery chart I could see these jumps also while it charging...
Pretty weird, if you don't have a app that analyze the battery status you'll never notice it....
There is anyone whos using GSam and can check if he also has this behavior (its on Chart->Power vs Precent Chart) especially happens on charging (not permanent, can be at any percentage)?
Also anyone have any idea why is it happens?
How do I know what is a good/bad voltage while charging/discharging, any idea how to identify thing like that?

!
UPDATE:
First I've tried this charger on 2 Galaxy S2 devices, charged them and confirm that there is no jumping or other weird stuff...seems its something with the charger and the battery.
So I tried my S2's charger (700mA) and done 2 cycles of discharging/charging with it, no jumping or other strange stuff...seems fine.
I guess its something with the OEM charger (which is 1.2A) and the/this kind of battery, maybe its not a bad thing after all... (someone said something about 'pulse charging', donno if its the idea on this behavior).
Anyway - if someone use GSam and would like to share if he experience this kind of things as I've described with OEM/non-OEM charger, it will be great.

-
Well after more then month another UPDATE:
Seems it dosn't matter which charger I'm using, at some point/points on charging the precentage will jump/drop randomally it could be only once per charge and could be more then 5 at once charge...
I still have no idea why is it happens, with other devices I never notice this kind of thing.
Again, if anybody could please check it with his own device if you notice this behavior (let the device charge full/almost full and check the graph/chart:
at stock battery you'll notice drop/jumps
with GSAM its easier- you can go to 'Power vs Precent Chart' and notice it as the screenshot that I've attached at 1st post, or zoom in the chart and see if you notice any drop/jumping of the 'linear' line)
Thanks in advence...

[Q] Battery Drain by 20% overnight :(

Hello Guyz
I'm really worried about battery drain overnight.
Last night I installed these apps :
-SetCPU
-Greenify
-Intellie3G
-GSam Battery Monitor Pro
Night I had exactly 88% battery. Morning when I checked I had 69% only. It is nearly 20% drop overnight. I have some apps running in the background (Aqua Mail) for example.
I've attached some screenshots. If anyone can help me to find out the reason for this battery drop it would be great.

Seems Aqua Mail is the issue. 4hours Wakelock!
Hey, Please use BatteryBetterStats to check the app that is causing drain.
http://forum.xda-developers.com/showthread.php?t=1179809
Run BBS, Turn on Root features and disable Google Analytics in Settings. Also remember to tick all possible options in log settings.
Charge phone full, unplug phone and leave overnight (at least 4 hours COMPLETELY idle), first thing in the morning, dump a log by clicking the share button at the top and selecting dump log.
Send the log saved in root of SDcard to me. I will take a look for you. Cheers!

[Q] Battery Calculation Broken?

This has happened multiple times on my Galaxy s4. Today was the worst however. My phone was on 51% battery (supposedly) and then, the phone just turns off while I was in an app, without any kind of low battery warning, it was running as normal before this happened, I start the phone up again and bam, 1% battery remaining. Here it is on the battery screen:
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",

"lightbox_download": "Download",
"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
My battery was dead by 2pm in the day which is also significantly worse than normal. This is with just 45 minutes screen on time:
and just 7 hours on battery:
And with no apps sucking up battery life.
Has anyone had this issue before and is there any possible way to fix this?

Charge to 100%. Pull battery. Put it back in and charge it again while off to 100%. If that doesnt fix it then get a new battery.

Hi ,
It could be lots of things...battery , phone not going in deep sleep , settings
First thing I would do is use an app like Better Battery Stats and really see what is going on ( kernel wakelocks) , who is keeping the phone up all the time , then i would review all my settings like FB , mail , location ...any syncing related app that may be going crazy and of course battery may be going bad

Look like a bad/faulty battery for me.

Keep in mind that battery percentage is never 100% accurate. All devices with batteries (with a percentage meter) has this.
But yeah, use better battery stats to check wakelocks.
Also a trick to calibrate the fuel gauche chip is to take out the battery for 3-5 minutes. It will be more calibrated than before.

Reasearch on LP idle battery drain

Premise:
idle battery drain in LP is much worse than in KK (1% per 1 hour vs. 3 hours.)
Personal experience : after disabling most of background apps in both OS's, the battery drain in LP is about 1% per hour, while it was 1% per 3 hours in KK.
New information:
I did a new test. I restarted the phone and charged it full. I then left it idle for about 6 hours.
Here are the results after 6 hours of a charged idle phone.

"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
Conclusions:
1) The constant wakelocks in idle state are due to S-Health app. They are not responsible for the battery drain.
2) Cleanly after restart, the phone drains the battery in idle mode at a rate of 1% per 3 hours, even in LP.
3) Something else is responsible for draining the battery at 3x the rate (of 1% per 1 hour.) This new culprit is only introduced on using the phone for a while.
I will continue testing this.
Any new ideas are appreciated.

The single biggest reason that I miss root is to figure out wakelocks on these things.

Someone posted a way to get Wakelock Detector working w/o root:
1) Connect phone to usb.
2) Do "adb devices" then do "adb tcpip 5555"
3) Open Terminal Emulator and do "adb kill-server" and "adb devices"
4) At this point, Wakelock Detector works.

Thanks for that info. I'll have to give that a try.

You can use wakelock detector without root, over usb adb

I have been seeing the same awake vs screen on behaviour, my fiance isn't seeing that trend as much and her battery life is better. I'm not complaining much about mine, but it could be better. I've tried clearing cache, battery pull, uninstalling apps, and changing sync settings.

Android Central published an article about the bad battery life on the S6. Samsung just updated the push service that affects the S6, S5 and Note series. Might be worth looking into.
http://www.androidcentral.com/galaxy-s6-battery-life-bad-update-might-help

I got wakelock detector set up with the instructions in this thread. It sort of works. It shows no Kernel wakelocks, and I think that it's very unlikely that my phone has had no Kernel wakelocks in the last 18 hours.

Yes I have been tracking this Note 4 with WLD for a couple months now and I haven't been able to pinpoit the issue of battery/wakelocks. It seems to be something very fundamental inside android itself. My wife's Note 3 absolutely does not have these problems. She can get 8 hours of screen time in a day. I am lucky to hit 4

Incorrect Battery Reporting | % Skipping | Dead @ 12%

Battery would fall 2% on the screen, it shows in battery reporting you can see the line drops steeply within 1 minute then stays stable (ignore the part where my device was asleep).
been very inaccurate with reporting % it randomly died at 12% (lowest its been since i got it 3 weeks ago) and when i power back on its at 2%. i charged back up to 40% and let it drop to 12% and the same happened.
i could live with the 3hr SOT if i got a good report of how much % was left so i can conserve usage if need be.
Running stock oxygen 2.1.1
then rooted and installed AK kernel (SOT is a little better) but still % dropping. i even super underclocked and saw the same effect
sent a ticket to OP - hoping its a defect and they can replace it

By what I read, it's a normal behavior when device wakes up from sleep.
It seems that, when device is asleep, even battery stats aren't updated, to avoid unnecessary drain. So, once it wakes up and you use it for couple minutes, android get a chance to record stats and update actual battery percentage.
Again, this is the explanation I read on such a question, and it does makes sense.

i managed to underclock enough to make the other percentages to show up - so it is working just i guess polling is slow.
the 12% dead battery isnt normal though. havnt had it since then but if reset a few times. now switched to a custom rom (keep loosing LTE) but ill figure it out, thanks!
