I checked my battery monitor widget today am noticed something very strange. It showed me 40% charged when I was sure it was only 35% charged before I went bed! WTF did it charge itself? As you can see from the screenshots the phone was not on charge and was awake for most of the night which has never happened before. I have not installed any new apps in the last few days I have never seen this before on any of my android phones over the years. After 1 month of using the note this is the first glitch i've noticed (if it is a glitch). I am on stock LA4.
Anyone have any ideas as to why this happened?
I'm not complaining ( wish it happened every night!) just curious.
I have noticed the same strange thing with ICS.
did you try pinching your arm?

It is probably/maybe your battery stats that was not exactly "right" and might "recalibrate" your battery stats to the true value.
The simplest answer is always the true one: It is having trouble reading your battery right. Happens with mine too sometimes.
LOL I had the same thing happened to me.
First day with my note. And so far I am loving it.(despite colour rendering issues , and a very lagging stock keyboard)

Maybe the phones are evolving and learning to use the sensor on the Front to charge itself lol

This has happened to me several times already since the Galaxy S days.. sometimes after a reboot the battery looses 50% and slowly charges back up its quite funny and strange, never happened to my note though.
What do you think happens if some of the services is not needed anymore and stopes relaying,the battery % estimation will go up.

Mine charged itself too.
Went from 30% to 50% when I was out.
I thought it has some solar panel hidden beneath.

Wtf are you talking about? That's not any kind of estimate of lifetime, that's a report on amount of energy left. And in this case, specifically, a bug in it's reading.

You need to review your facts make a bit more research, the report is based on the fact that how many apps and services are you using,say if the wifi is on, it will show you certain %, however if you turn it off will report you that it has increased, depending on the running apps and services how much battery is left, my laptop does it all the time,unless you are living in pre Smart Battery Meter era.
I have to agree that if the % relies on the voltage (as I am sure it must do to some extent, but I am only guessing), stopping heavy services will allow the voltage to increase and the app may see that as a gain.
Alternatively we have discovered Samsung's secret OTA charging method! This explains why some phones have terrible battery life, they are being sucked dry by nearby 'Vampire Notes'!
Now, if we could just work out how we could charge all Notes by sucking iPhones dry ....

Battery is trolling
The Galaxy Note battery is a three terminals battery. So I think that the % state of charge of this battery is directly calculated from its output voltage.
The voltage decrease as the charge decrease, so it is possible to evaluate the residual charge in the battery.This is not a very precise method but it is quite simple to implement.
After a high current drain there is what is called a ''voltage recovery'', the battery voltage increase slowly a little bit as the current is stopped. So you may think that the battery get back energy, but unfortunately it is only an artifact.
Yesterday I showed you all how my battery indicated that it had charged itself.
So guess what folks today when I checked the complete opposite happened!!
Again as you can see it went from 48% just before I went to sleep only to wake up to a dead phone (switched off). Upon rebooting it showed only 9% !!
Now I can cope with it going up but going down is not good.
Hope its not a hardware problem and just a faulty battery.
lets see what happens tomorrow maybe it will explode!
I'm an EE (election engineering) student. Michel_7 is right. Lithium ion batteries experience a voltage sag during high current draws. Afterwards there is some rebound, both as the battery cools if over temp, and with a period of lower activity. This is in part due to the fact that batteries have internal resistance, and as they supply power, they also dissipate some internally. This is of squared proportion to the current drawn. IE current^2 * resistance. Battery resistance constant, so the more power the phone uses, the more the battery does. This is what heats up the battery.

My husband was getting annoyed with his battery life on his tablet so let it sit for a few days to see if he could catch what was going on. It seemed to be doing fine, with a very gradual, small decline in battery life until last night sometime when it suddenly tanked and when he woke up it was dead. You can see it in the image from battery stats.He was on AOKP and ktmanta (which i was also running with no such issue). Location services and nfc were turned off. Any ideas what might have caused it? I don't see anything standing out from the battery info.
bad hardware. Something is shorting or grounding out probably and it is releasing all of its charge. Nothing else I can think of is able to drain a 9000mAh battery in a ~few minutes time
Not even locking the processor to max speed with 100% load can drop the battery that fast

Guys last 1-2 week i started having battery problems. My phone dies when 10% battery left and when it has full battery it shows 89-95 etc i tried everything but nothing fixed the problem. Tried *#0228# code and didnt help and its not rooted so i cant use calibration apps. Only pulling the battery out solves it but after 1 usage it happens again. And its weird my 2 other note 4 user friend also started having this problem in same time any1 else has this problem or any1 knows how to fix it properly?
Sounds like a dead battery to me.
If the phone shutdown at 10%, it's probably because the voltage delivered by the battery is too low.
But the fact that your friends have the same problem is pretty strange. An app maybe ?

Dont think its an app and dead battery. Btw it doesnt only die at 10% sometimes 5% sometimes 7% its random. I think its just wrong calibration but it happens usually. Maybe fast charge effects battery dunno but its very annoying.
Defect charger that you both share? That ofc killed your batteries

Every1 uses their own charger. And im pretty sure my battery isnt dead i can still get 6 hours sot easyly.
im having the same problem.. it dies on me at 10%... last time on 20% cause i was like skypeing on 3g network for the last hour or so.. i got the phone SH so.. maybe replacing the battery will fix this?
This is curious. It's been this way for about a day or so. No actual battery life issues that I can tell. No heat or performance issues. Battery calibration?
T-mobile rooted and my only mod is AdAway.
Other than this issue, all is normal.
Thoughts?

Someone else reported something like this in another topic. I can't remember what type of V20 they had. My thought was that the battery was bad.

I'm almost 100% certain that it's a calibration issue. 100% software. There were similar issues in a Samsung 6.0.1 ROM as well. Bad battery would be never reporting as "FULL" to the OS. Fortunately, even if it's a bad battery, thank jebus for replaceable battery!
One of the things I'm trying was to pull the battery, hold the power button down to discharge any capacitors in the charging or power circuits and then replaced the battery. Now it shows 89% and charging as well as "collecting battery info... please wait.". I'll let you know if it breaks 94%. I think the calibration was off after going a full day of constant usage but plugged in (drove 10 hours while using Waze).
Definitely a calibration issue. The above method had the predicted effect. Fully charged at 100% again. Spread the word. FYI, I held the power button for a good 30 seconds with no battery in the phone and obviously unplugged.
Peace!

Well, you see, at first I thought it was a bad battery, but last night, my battery began acting funny. It was at something like 40% and then I did 1 reboot and then battery was at 25%. Then I had to reboot again, and battery was suddenly at 18% and stayed that way for a long time. I decided to try the calibration thing and it may have solved some of my battery issues (I did a few other things too, so not sure exactly what helped). I was always told that battery calibration was no longer necessary. Something about the way that Android reads the voltage of the phone rather than the capacity now... Or something... I forget the technical mumbo jumbo. Anyways, that's one reason I always had been telling people that calibration is just a placebo and that their battery may just be bad. Now I'm not too sure what to think!

Hello,
I've had my GS8 for less than a year now and during the past few weeks I've noticed a weird behavior going on with my battery.
When the battery goes around 15% it then drains these 15 remaining % really fast in around 5 mins.
I've been wondering if any one had seen this problem, and if some of you know if it's a software or hardware related problem.
Thanks for you answer

Kind of but be aware these samsungs and others with non removable battery have issues call deep discharge bug
Bassicly if the voltage reaches a low point there is a possibility that they do now want to turn back on....
I would always recommend charging at 20% or higher on these devices any ways

Yeah I'm trying to keep the battery as healthy as possible but some days I just can't have it line up perfectly ^^
I'll see how it turns out in the future anyway
