Battery stats reset after reboot??? - Samsung Galaxy Nexus

Hey guys.
I've had an Inc S for some time so not too new to the android world.
But my new Gnex resets batt stats after a simple reboot. Is this normal? My HTC never did that.
Cheers guys.

If it's a brand new phone, the OS may still be collecting battery data so technically speaking, it could happen.
Don't quote me on this though.

Hrmmm, dunno hey. Thanks for your reply though = )
Has anyone else had this issue??
Thanks.

Are you rooted? Running stock ROM?
Afaik the battery stats file only gets deleted when your phone is fully charged. Did you reboot at full charge?

Yeah I found that anywhere between 90 and 100% its wiped after a charge. I rebooted after or in that 10% so it sort of makes sense. I recently rebooted and it didn't clear them. It must only do it in that range. Or rather like your saying at full charge, well close too anyway.
Thanks.

Battery stats are wiped every full charge.

Question with battery

I purchased the official Seidio 3500 mah batteries for my evo and the wifes evo. After a full charge, her battery under normal usage all day and night is at 57%. My phone after a full charge and barely any use whatsoever was at 13% after an hour..... We are both running Azrael x3.0 rom with the newest htc kernel #15... any suggestions?? Maybe my new battery is faulty?? I would expect this from ****ty ebay batteries, but not something official!! Any help would be greatly appreciated!!!

Try eliminating a variable by swapping batteries with your wife....then use your old one again.....if both work well then you have your answer......

Swap batteries ... if hers only lasts a short time in your phone then issue is with the phone. Then you can start troubleshooting.
Edit: Ha I was a few second to slow!
Ok I will give that a try.... I noticed in the battery left widget when I go to usage, the very first one says "running" 84%, and I click on it, basically it is stating that the phone isn't sleeping when I lock the phone..... could this mean that the everything is staying on when it should be sleeping?
Thank you for tips!!

Ok after being on the charger for all night, I unplugged it, and really haven't done anything and I dropped to 90 % within 8 minutes.... I haven't had a chance to try my wifes battery yet, but im thinking this one is definitely faulty...
Why would android system be at 63%???

Dropping the first 10% quickly is not a certain indication that its the battery....your battery charges to 100% and then, begins to be used up to 10% before it charges again.....so you could have been lower than you thought you were originally ...thus making it appear that you dropped 10% in minutes.....if the remainder of the battery does this then I still recommend you try swapping with your wife to eliminate or confirm
Sent from my rooted evo using the xda app
Ok well I just wanted to say thank you guys for your advice, but I think I figured it out.... I think that some things within the phone were not getting along. I flashed the SBC-Net-4.2.2-more-havs kernel #11. I fully charged the phone, including bump charge, and I left it on for about an hour or so longer, and I have been unplugged for 1:44, and my awake time is 45 min. I am still reading 100%!!! So I think I am good to go....
Thanks again guys

Battery Doesn't to Charge 100%?!

I just got a Nexus and rooted, etc, using the toolkit.
I've noticed that the battery will not charge all the way to 100%, no matter how long i let it charge.
Yesterday for example, i used the phone till it died, then connected the phone to the charger over night.
This morning i turn the phone off and see that the battery is only at 92%!?
How can i fix this?!
Currently running Vicious Jell Bean v4.
Perhaps this is why there is an option to clear battery stats in clockwork, yes?

That doesn't actually do anything aside from erasing your battery graph.
Yeah from what I've read, clearing the battery stats using CWM or some other calibration app, didn't take care of the whole problem.
Any other ideas?

Does the kernel you are using have BLX?
That can be used to put a limit on how high a battery charges, maybe you changed the value by accident or it was set that way by the dev.

How can i tell?
Not sure but i didn't use any other kernel except the one that came with the Vicious Jelly Bean rom.
I just noticed that you can change the mAh capacity in the "Battery Monitor Widget" by 3C.. it currently shows that capacity is 1750mAh when the stock battery states 1850mAh. Should i change the value now and drain the Battery completely, then full recharge?

I think thats what is called, My phone never goes past 99% no matter how long i leave it there so now when it reaches said 99% i unplug it and re-plug it inmediately and it goes up to 100%
Sent from my Galaxy Nexus using xda premium
what the crap...
I super-wiped, deleted dalvik cache, and factory reset, and flashed the Rev' HD rom, and STILL doesnt charge past 92%?!?!
Perhaps its the "Battery Monitor Widget" from 3C and the data stored?!??
Same happened to me. And it's getting worse progressively - first it was charging to 89%, then it didn't go above 79, now I can rarely see it go over 60
Since day one my phone never got to 100%, it always stops at 99%...
My phone was able to charge to 100% within reasonable time. I've changed a few firmwares with full wipe, that didn't impact neither the ability to charge to 100% when it was able to do so nor the inability to charge fully when the problem surfaced.
I suspect that problems started after I dropped my phone (wasn't a hard drop, just a fall to a hard surface from 0.5 m, no visible damage).
Is it possible that the battery gets damaged somehow?
Same problem

Same problem here, my phone charge until 84% BUT:
I tried with a battery of my friend that was at 95% and my phone showed it 60%!
The issue is in the way that our phone measure the battery, but i already tried wipping bat stats and nothing...
I also wiped all the things and re-installed 4.2.2 and same problem
Why would you even bother eating your time wiping battery stats? It had absolutely nothing to do with charge indication.

My GNex Battery gets to 30% then just dies.

hi i have a
Gnex
im using
>Codenameandroid v3.3.2
>Trinity kernal
Everytime my phone reaches around 30% my phone just dies, then wont start till i connect it to a ac wall charger.
i have two batteries and at first i thought it might of been a ebay battery i purchase but it does it with both.
any help?
Try to wipe the battery stat in recovery.
I tried wiping it Ndnit continues to behave this way. Thank you for replying

Did this just start happening with the new kernel? If you are sure it isnt a hardware/battery issue, I would set it back to stock and see if that fixes it. Hopefully its just a bad combination of kernel/rom. Good luck !
You know what it might be the kernal I using the Trinity kernal experimental 537. I'm flash back to the stable version. See if that helps.

If i feel like battery drain or something like tat.. I do wipe cache and dalvik and install the ROM and fix permission in CWM...
Then it will be back again..
Its my Daily driver. So most of the time i will be on Calls and msgs and also Wifi and bluetooth will be on 24/7
Auto Sync on..
My Battery will Remain till nxt day morning and still i will be having 25~30% left out...

Battery Life

I recently bought a GSM galaxy nexus (NTT DoCoMo version) and I use it on T-Mobile's prepaid network. The original battery that it came with was terrible.. Literally only lasted 7 hours regardless of screen on time. So I bought a stock Samsung battery off eBay thinking maybe it was a bad battery. No help whatsoever. I've flashed different ROMs, radios, and different kernels. Can anyone help me figure out what's going on? I had a Sprint Galaxy Nexus and I could get up to a day on the battery with 2.5 hours of screen on time so I know the Galaxy Nexus can last a long time. What's the deal?

Could you post some info on battery drain statistics from battery settings tab or preferably gsam monitor over a full drain? I could probably help you out, just need some more info. Also try flashing fancy kernel if you haven't already. This is a newer kernel that gives the best battery life you'll find freshly flashed.
Before discharging toget battery stats I would try charging to 100% and using "battery calibration" by NeMa to clean your phone's batterystats file and then drain to zero with a screen flashlight or running gallery slideshow. This can always be a problem no matter how healthy your battery is.

This is what I have showing for my battery so far. I flashed the newest radio last night and that seems to have helped a little bit with the battery. I have tried the battery calibration and it didn't really seem to help much.

I have flashed a stock 4.2.2 ROM a week or so ago and I was still having this issue. I bought a new battery too and its still happening. Flashed the fancy kernel today and it seems to be helping a lot actually.
Sent from my Galaxy Nexus using xda app-developers app
The stock kernel performs way better then what you are experiencing. A custom kernel may help a bit, but it's not magic. I'd recommend using the app BetterBatteryStats in order to find out what's going on.
Do any of you think that me restoring apps would have anything to do with the battery drain? I'm not seeing anything out of the ordinary in the GSAM battery stats but the battery drains way too quickly. 10% per hour even when I'm not using it..

Glad to hear that fancy kernel is helping. It's probably the closest thing to magic you'll find. I agree that 1 hour of screen time and under 12 hours is under par, but I was having these same issues 2 months ago and could not believe how crappy battery life was. It really got better though trying a bunch of different radios to find the right ones, using minimal gapps/resource hogging apps as possible, finding the right build.prop tweaks to use, and most helpful flashing some good reliable kernels like fancy and AK/anarkia that have incredibly useful customizations that stock just doesn't have, I.e., contrast and color settings, battery friendly governors and frequency profiles, optimized smart-reflex, and custom regulator voltages for display.
Well, didn't feel like it lasted too long. Fell asleep with my battery at 33%, woke up 3 hours later and it's dead. I'm ready to throw this phone out the window.

I've tried to find a rom and kerneI that would help with battery too, nothing made that much of a difference though. I use the 2x battery saver app now. I get at least double the battery life sometimes more.

I see you got the app. Good. Now a few minutes isn't enough time to gather reliable stats. Review the results after a full drain cycle of the battery. Check partial wakelocks and alarms for suspicious activity.

Here's what was listed on BBS after a full drain. Do you see anything unusual? I turned my data on and kept it on 2G to prevent the no or unknown signal from eating more battery but that was the only change. Battery life still looks terrible.

No need for the snake oil app, as simply unplugging the phone after a full charge wipes battery stats. Wiping battery stats and draining to zero aren't going to have any bearing whatsoever on this issue and would needlessly shorten the battery's serviceable lifespan.

Whoops.. I forgot to screenshot those. I'll get those later today. So I put my phone in airplane mode to see if maybe it was the reception... Phone kept draining. I will try to wipe everything off the phone later and not install any apps and see if that helps.

According to these stats, it looks like Google talk and the calendar are my biggest wake locks? I disabled Google talk, turned off location history for Google maps last night, what should I do about the calendar? I feel like my phone is becoming useless because I have disabled so many things.

Battery not discharging properly

Since installing 4.4.2 my battery isn't discharging, at all! It's been stuck on 100% for the past four days. I haven't really used it much since but the battery should be way down by now.
Isn't that a good thing?

Are you still having the same issue?
Because I think I'm maybe having the same problem.
My tablet keep shutting off at 40% as if is 0%. It all started since this past weekend.
My tablet is unrooted ,try to search the web for a solution but haven't found one yet.
I'm trying avoiding to do a factory rest because I read the issue still persist.
Everytime I recharge my tablet it stay a long time on 100% and the moment it reach 40% it shut down a,msg appear saying battery low and shut off.
Also take note I've read about those app calibrator but keep reading that a myth.
Let me know if your still having the same problem?
No, I actually fixed the issue. Believe it or not I used a calibrating app and Root Cleaner and did a full clean and it appears to be working as normal now. I'll add later which battery app I used, can't remember the name.
EDIT : Actually it was just Root Cleaner. It has a batter calibration setting.
