Dear all, somehow I am experiencing an odd behavior with the battery stats.
Once the battery stat reaches 1%, the phone still remains on for maybe another 15-20min of use until it goes off. Is there anything wrong with the battery, my settings or not proper calibration?

UPDATE:
Since my first post on 1% battery my note is still running. Playing music all time with switched off screen.....
Really strange behavior

Just a calibration issue I would think. Try resetting the battery data in recovery and also use Battery Monitor Widget to further calibrate it.

i was having similar problems with mine, i tried turning the phone off, removing the battery and then restarting the phone and charging to a full.....that somehow fixed the issue for me....and also as described above use a battery monitor widget for correct stats.
Did you discharge the battery fully first?

not fully, about 20% charge was left in it, but i guess it doesnt matter as long as you take the battery out and then recharge it back for a good 12 hours or so- supposidly longer charge cycles = more accurate stats.

Lately my phone will go through a massive drain until it hits around 55% then it will drain normally. I have not changed anything since this started. Any suggestions? I'm thinking I may need to calibrate my battery.

That sounds like a good idea for your situation.

Thanks for your input. I want to wait a few days before I do it. So it will give it time to see if that really is the problem. This only happened yesterday and today so maybe tomorrow will be better. Besides the only time I really have to do it is later this week.

How does one calibrate a battery? Is this the same thing as "conditioning?"

You charge your battery to 100%, wipe batterystats.bin, then run the battery down to 0%, then charge uninterrupted back up to 100%
Battery Calibration does it help ?
I have a similar situation and i followed the battery re-calibration method too but still didnt help.
Situation - The battery would charge till 88% but will show its fully charged. Recently put Vivokat so now its even more prominent. Every reboot drops the battery by steps, like i would reboot and the battery would go from 80 to 65 just like that, no gradual decline or anything. And even after a full charge (the green light indicator is on) still the battery would continue charging.
Tried - I tried resetting the batterystats.bin file as suggested, fully charged till 100% then removed batterystats.bin file then allowed to discharge all the way then charged continuously till 100%. No outcome
Anything else that can be done ?
I understand this is a sensitive subject to bring up, as there are 10 battery threads popping up each day.
But I think I have an unusual battery problem...
My Galaxy Nexus eats pretty much the same amount of juice whether it's powered on or completely powered off, and I get about 8h out of my batteries.
I have 3 batteries, and all of them give me about the same battery time.
I just did a short test:
1. Charge battery in cradle to full.
2. Put the fully charged battery into the phone.
3. Power on phone, and check battery - 99%
4. Power off.
5. Power on the phone 30 min later, and the battery is down to 91%
Can anyone out there give me a hint as to what can possibly drain my battery when the phone is powered off?

your batterstats can be off a little, or your 3 batteries are bad.

If your phone is draining a significant amount of battery over a matter of several hours....say...20-30% or more during an eight hour period of being turned off, then something is wrong with your phone or batteries (less likely with all three).
I suppose it's possible that all 3 batteries are bad, but I find it unlikely as I didn't buy them at the same time.
I have tried to reset the battery stats from the CWM recovery menu, but I read earlier today that resetting the battery stats does not influence battery time.
8h, then the phone shuts off.
Or leaving the phone powered off for about the same time, I can't power it on as the battery is completely drained.
Once your battery is fully charged it will stop charging the phone but continue to display that it's "charged" until it drops below 90%.
After you restart the phone it will display the current charge.

When your battery dies when it is off it is not doing what you are describing.

Fyi that was only true on previous nexus like the nexus one. The gnex driver does not work this way anymore.
Might be a rouge app. Post a picture of your battery stats.
Swyped on my CM9 Galaxy Nexus
The other question is if the problem is a new one or something that's been going on since the phone was new?
He said even if his phone is off.
All these points to hardware issue.

It is weird that the batteries drain when the phone is off.
Heck, even with only display off you should get even longer battery life.
But.... eight hours of battery life per day for the Gnex sounds "Normal" and "Right" to me!
If all three batteries are the same, than you should check the next logical step. Bigger Batteries.
Here is one from Amazon...
"Seidio BACY38SSGNLN-BK Innocell 3800mAh Super Extended Life Battery"
Hardware issue with the phone.
There is no way you should be draining a charged cell in 8 hours.
..this might be silly...but have you tried charging the batteries in the phone itself? (sounds like you charge them externally only)
defective hardware
I agree that it is probably defective hardware.
When a device is powered off, the battery should drain very slowly.
It might still be helpful if we could see a picture of your battery stats.
Here is mine, and you can see my screen is taking most of the battery life.
Which is because I have it set for max brightness.
Hi guys
recently i bought new battery because my old one used to jump
from 70% to 100% and had really bad battery life.
i replaced the battery and calibrated it and i noticed that the 20% from 100% to 80% goes down realy fast
should i recaibrate the battery?
what should i do? thanks!
It depends on the rom u r using.
All roms except stock based roms have this problem.

Im using aosp by maclaw studios
the weird thing is that the 70% acts like it 100% and im having really good battery life
from 70%
Its a problem in sumsung charge system.
In custom roms when u full charge battery it is about 80 % charged.
Sent from my GT-S5660 using Tapatalk 2
I think you should charge it when the phone is turned off. I noticed that my phone tells me it is "Charged" when it is turned on. However the actual percentage in Go Power Master is 80%.
Sent from my GT-Xperia S using xda app-developers app
so it has nothing to do with the battery quality and the battery calibration?
the problem will not appear in the stock rom?
Thats if needed. To check if the battery is fully charged, try these step.
1. Charge the when it is running until it says "Charged".
2. Turn off the phone and keep the charger plugged in.
3. The battery image will appear. If it is not full, wait till it full. When it shows 100% then it is fully charged.
Note that powering up the phone takes some significant amount of battery. If the battery is still draining fast. Calibrate may be needed.
Sent from my GT-Xperia S using xda app-developers app
enchanced rom shows 100 percent but still shows charging. So I guess it fully charges
Well the battery level seems to be jumping unusually from time to time . What i do is i wipe the battery stats from cwm , i leave it over night to fully charge without doing anything to it , calibrate the battery with `battery calibration` from playstore , full discharge and full charge again . I do this after each rom that i flash and it seems to do good and seems to point the right amount. Anyway the charge lasts as i hope it lasts , from 1 day if i do stuff with it like some wifi , some messaging , many minutes of calls .... to about 3 days if i do only calls. Cheers
Hi all.
My GNexus's battery charging but the battery stays at %98 and not charging. I've tried another charger and plug but situation the same :/
But I'm trying charging on pc via USB cable, In this way charging smoothly (%100)
What can i do?
Its normal.

If this is a normal why the other phone (other gnexus) charging fully every time?
You could shut off your phone, and load it without android running, after 3h it should be full
And then try and boot up
Happens to me from time to time I noticed if I pull out the charger and put it back in (that's what she said) it will continue to charge the rest of the way

Could be your battery limit on your settings ,if you have trickstermod see if your battery limit is 98 (ps .its suppose to make your battery last longer in the long run )
Sent from my Galaxy Nexus using xda app-developers app
Even if your phone shows 100% it'll go back to 98-97 in a few seconds, it's how the battery is made, theres some technical info. about how/why it's like that but its simply how it's meant to be charged and is perfectly normal =]
I have a few other devices who charge to 100% and stay at 100 for like 5-6 minutes when used. I hate when I wake up and see my phone say "Charged - 98%"
Sent from my Galaxy Nexus using xda premium
This seems to be the way the Gnex calculates it's battery. I can't ever get 100% unless I practically force it too with unplugging it and plugging it backin. In ICS roms on my XPlay i could wake my phone 4 hours after unplugging it and it would say 100% (after little to no use of course). I still got similar real use battery life to my Gnex though.
The battery percentage is a calculation, not a physical amount of juice your battery has.

Hello everyone,
I observed a strange behavior of my arc s , when the phone reaches 100% charge and later when i unplug it my phone spends almost 20 minutes at this point and after some time it starts to discharge ie. it comes down by 1%.
But if i use it hear after it discharges rapidly.
I find this behavior very odd !
Can anyone explain me this behavior ???
Thank you in advance.

Check battery use
Check battery use to see what is consuming the battery
Maybe WIFI and sleep policy,Bluetooth,Network type WCDMA/GSM ,GPS and accounts sync ?
Observe the diagram or the slope in the battery use to see is your battery draining fast or is it normal,also what rom and kernel are you using
Isn't that the normal behaviour of a battery coming from a smartphone? .-. Mine's like.. 20 minutes on 100% before starting going down, and it doesn't affect my overall battery life at all..

I have observed all of that.
Everything is fine, as the display uses the battery predominantly.
My guess is that is a sign for use to change the battery.
And also i see spikes in chart instead of going down the charge goes up and down.
Sent from my LT18i using xda app-developers app
how old is the battery?
how old is the battery ?if the spike goes up that means it is connected to USB and the phone is charging .attached is my battery usage 7 % in 11 hours the slope is continuously going down as it's been unplugged and running on battery only ,phone and battery are a year and half old
The "spikes" you refer to are because your battery isnt well calibrated...
You can charge it fully, use it and when its around 5% charge it again to full. And if you delete the battery stats your battery must sette down over some day or two.
But for a better response you need to upload a picture of your battery stats.
My battery sometimes stays in 100% some minutes, some other times is goes down to 99 very quicky, but its normal for me cause it usually lengths for two days + with normal use

Yes i totally agree the oly time the graph should go up is when its plugged in and not wen unplugged.
But i sometimes see the spikes when unplugged.
Nevertheless it has not degraded the performance.
