[Q] help!! I want my 59% back! battery stuck at 41% - Nook Color Q&A, Help & Troubleshooting

Hey guys got an issue i've seen several people have but nothing i've read fixes mine. So here it is. My battery meter is stuck at 41% no matter what i do. When i plug in the cable it looks and acts like its charging and it even goes green when its fully charged. Then i can use it till it powers off and it never stops reading 41%. I tried calibrating apps. I tried other battery widgits. I tried reloading roms and clearing battery stats in clock work recovery and letting it run down to nothing. Before anyone asks, yes i used the stock cable in fact i used 3 different cables. I am running 1.4.1 rooted with mn and no oc. i had this problem a 1.2 before i updated to 1.4.1 hoping it woukd fix it but no dice. i even loaded battery monitor widgit and it registers plugged in and unplugged but non of the stats come up or refresh. Any help would be greatly appreciated

It may be a hardware problem. How long does the battery last? Is 41% the max or is that the only value it ever shows?

i get normal battery life length and everything else acts normal which is what drives me nuts! but its always at 41%. plugged in 41%. freshly charged 41%. 2 seconds away from turning off 41%!!!!!!! 41 has now become the number i hate the most!

Just questions to try to understand a bit more. If you go into Spare Parts app and check battery information what does the battery level and scale say, and does the battery voltage change as you let it discharge.
Also when you say different ROMS, have you tried say running CM7 of an SD to see what this shows?

in spare parts the readings never change. i have tried cm7 same thing!

Wow, I have the EXACT same problem!! Well at least yours say 41, I'm stuck on 29%. I've tried the same things you have, but I'm still 29, . I check the threads on occasion hoping for a solution but nothing. It still functions fine, I just never know when it's going to cut off on me, because I never truly know how much battery life is left. I just try to charge often till the lite is green, then I know I have time.

Go to CWM recovery and wipe battery stats. Some people say it helps, others it does nothing. But it won't hurt anything to try. Also only use the stock charger and stock cable to charge.

Mine has just gotten stuck at 34%, otherwise the same set of symptoms. Has anybody come up with a solution other than unplugging the battery?
I've installed several different CM10 ROMs, told Battery Monitor Widget to forget its history, but it, Settings/Battery, and a couple of other apps and widgets are all flatlined. I even deleted /data/system/batterystats.bin to no avail.

That did it! Everything appears happy now. I deleted the file and rebooted. The level was sensible, and after plugging in, Battery Monitor Widget showed Charging for the first time in days.
Thanks! Much better than opening this thing up!

Just open your file manager and look for /rom. It is right there. I don't know if it has to be a root file manager though.

May have to be. I've just got the standard file manager on there and I can't find /rom. I typed it in, but it only opened to an empty file. I'll DL explorer and try that way.

Try Root Browser Lite. It is free and does root.

Yep, I did it with Root Explorer, but (especially if you're a Linux command-line sort) in Terminal Emulator, just type su, then cd /rom, and rm is all you need.
Good luck!

System Process gone crazy! Depleted battery

I used my phone for a 10 minute phonecall this morning, I did a little bit of wireless tethering to download some ppt files for my mba class on my laptop, and then I just did some basic surfing on the phone and using the xda app.
My battery level was at 80 at about 12:15 pm. I left for a little bit, leaving the phone where it was, and when I got back around 1:30ish, I looked at the phone and the battery level was 70. That's very uncommon and I was really surprised that it had dropped more than 1% or so in such a short time. And within a few seconds my phone just rebooted by itself. And when it came back up, it was running VERY VERY sluggish, and I opened up system panel, and my CPU consumption was at 90% or above. I had to reboot into recovery and wipe dalvik cache and cache, now the phone is running like normal.
I looked at my system panel monitoring data which I had running, and I'm posting the screenshots of the historical data.
It seems something suddenly happened to the system. I can't figure out what it is. Can anybody point me in the right direction?
Check the logcat.
If you see a message saying something like "Can't read CPU frequency linked list - next isn't in the list" or something like that repeating endlessly as an error, and you happen to use iR's kernel, then it makes 2 of us and you can show him the logcat to debug.
I wanted to debug it, but I don't seem to find any time.
I'm using wild monks kernel that's listed in my signature. How does one do a log cat anyway?

Wildmonks' kernels are based on iR's source, if I'm not mistaken.
Go to Market, search "logcat".

correct.
I see the battery drop from 50% to 0....did you change anything with the battery calibration app?
I set my battery health to 100% from 94% and my phone switched off at ~25%. Try wiping battery stats.
Happening to me too. If you click on System you'll see it's really the suspend process. Typically on my N1 there is nothing in the log.
See here for further discussion: http://code.google.com/p/android/issues/detail?id=11126, "suspend" process runs continually in background at ~40% CPU on HTC EVO 4G
I had this problem too.after I installed look out on my phone, I notice that my phones battery was dropping significantly fast. I thought it was the look out app that drain the battery since it's a security app and should be running constantly. But it's not though cuz I installed the app on my wifes g2 too and hers is fine. Hers is stock btw and mine is running cm6.1. But after 2 days and few time rebooting it, it's fine and normal now.
I usually make it through one heavy using day, but when the problem exist it can barely make through half a day. I start my day at 8 and stop at 6

Anybody come up with anything on this yet??
I can confirm this issue happens with a whole bunch of iR's and WM's kernels. On the other hand, never happened on stock Enomther's kernel.
You can use OS monitor to see logcat or even dmesg log for battery stuff too. And you can use that app to export both logs to memory card whenever you want. I do that all the time to analyze my log from a computer when testing the battery calibrator app when developing new one.
No clue why that CPU is happening though. I, too, purchased system panel and It's by far the best app on my phone.
I had this once. It was a corrupt photo on my SD card. I formatted it, restored some files, and it never happened again.
Unless you really go through all your logs line by line I don't think you can figure this out. This includes both logcat and dmesg.

need your best batterystats.bin for best battery life

hey, i'm currently running cyanogenmod #21 came from bionix 1.3.1, got really ****ty battery life, i have deleted batterystats.bin when i was running bionix, and i deleted it when my phone wasn't in 100% battery, so now with cm7 i still got the same problem,i searched the batterystats.bin in system but i couldn't find it,then i wiped battery stats from CWR after full charge and drained it, but still got ****ty battery life, btw can you guys provide me your best batterystats.bin for this lonely poor guy

I don't believe batterystats.bin works that way. It's a file that is automatically generated by the Android system so just putting someone else's file on your phone isn't going to give you great battery life.
The file is in /data/system. Check again and if it's not there and you are not plugged into power then you may have an issue. Reboot and see if it shows up and if not try odin back to stock and flashing CM7 again.
Also the app Battery Calibration is very good calibration program.

One thing that was mentioned in the CM7 vibrant threads was to manually delete battstats.bin because it seemed cwm wouldn't actually delete it sometimes.
Using either terminal emulator (em /data/system/battstats.bin) or root explorer, delete the file.
Also, turn off data when your don't need it or aren't using it, use wifi when you can (uses less power).
Sent from my SGH-T959 using XDA App
The correct process is to fully charge your battery, wipe the stats file, then use the phone normally (without plugging it in or otherwise charging it) until Android shuts itself down.
Basically Android needs to start with a blank slate and see what your battery life looks like with normal usage, otherwise your meter will always be incorrect, it will jump around unpredictably, and will probably auto-shutdown at the wrong times. Keep in mind that your phone is essentially a small PC; you want a clean shutdown if possible, instead of the battery-equivalent of just yanking the power plug.
As others have said, you shouldn't use someone else's files, and unfortunately you really shouldn't ever swap in other batteries as they will perform differently. The battery profile also tracks information about application power consumption, which is why you should use your phone normally -- and the stats should get slightly more accurate over time.

This gentleman's got it right on the bulls eye.

You MUST delete it manually.
through CWR or the Clibration app, it won't work.

Sorry for posting in an old thread but...
Calibration is a myth, and does not improve battery life whether indirectly or directly...

That was a post by a Google engineer. It also has a long conversation involving other engineers.
Short summary of the page in points:
batterystats.bin does not store data about the battery itself.
batterystats.bin's only purpose is in settings>about phone>battery use
batterystats.bin gets renewed each time you charge your battery.
Calibration does not exist. It is a myth.
The best way is to charge to 100% , root explorer, data/,system/,batterystatsbin and delete it and reboot.It will create a fresh bin shortly after boot.Drain it about 2-3% and charge fully
I have been running bionix with bail uv and I'm getting a day and a half with heavy web and talk for 3 months without one freeze.

Odd thing happened

Just got this phone like two or three days ago. Today when I pulled my phone out to use it it was dead, wouldn't turn on or anything. Pulled battery and then it powered up. Got the low battery alert. So here's my question on the photo i posted, what could of made the battery drop like that?
Sent from my at&t SGS2
whats the other screen like? what i mean screen on time, and how long awake its been on? cause if those two are on all the time that could make the battery drain...
try charging it to the fullest and calibrate it using a calibration app and see how that goes....
sorry if i cant suggest anything else...charge it to the max and calibrate it and see how you do after a few cycles

Screen was on not even two hours. Awake time was about the same. It was just odd that it dropped off like that. Last night I flashed the latest villain rom and its been ok but really haven't used it and I'm at 63% with 58 minutes screen on. I also did the calibrate battery, maybe I'll go in and clear battery stats next?

I think my battry have problem becuse i bought the nook color from my friend.
If my battry have problem i think i cant find it in afghanistan thanx friends
1. use the wall charger, it charges real fast. charging from a laptop with the included cable is not a good idea.
2. There are a lot of things you can do to improve battery life, most of which will require rooting and flashing a different ROM besides stock, just so you can get to the settings that make a difference. 5 hours of battery life on a stock NC playing videos is probably about right. I get 10+ hours of video out of mine with extensive tinkering. Far and away the biggest factor is the screen brightness, and beyond that, how bright, on average, is the video. I watch movies with brightness about 9-11%.
thanx mr 72 for replay
i am using cm7 custom rom
So what should i do to do beetter for battry life i am watching vedio in 0% brightness plz help i want to see vedio a bout 10 hours if poossibl thanx
Battery life will be affected by any radios, screen brightness, and CPU clock speed. The nook is not meant be charged over USB, but as you can see, it is possible. If you're looking to get a ten hours battery life, and you've purchased and rooted the wrong tablet. Id say nook color can get anywhere from 5-7 hours based on the above factors.
Mine takes 4 hours but my nook needs to be off to charge. If it is left on even with the screen off and saying charging, the battery is actually going down. Kinda stupid but whatever this thing is cheap greatness lol

NC can certainly get 10+ hours of battery life under normal use, and up to 17+ hours in my experience if you are using apps that require no wifi, low CPU and can tolerate low brightness settings.
Follow the guide in my sig.

That's "on" time.
17+ hours of actively reading ebooks (Moon+ reader in my case, black text on off-white background, no wifi enabled [was on a plane], brightness around 10-15%)
10+ hours of actively watching movies (MX Video Player, movie format varies from 720P to 480P DVDrip h264 and xvids, also no wifi, on a plane)
I say "+" because I quit using the NC and there was remaining battery, so I don't know how long it would have run if I let it run to zero. Check out my guide (in my sig) to see how I set mine up. There are no settings that compromise performance or utility.
I find charge time can vary pretty greatly. Last night i didn't get a full charge with the same settings that I had the night before.. aside from updating to a new nightly. Generally I can charge the device in less than 5 hours if the wifi is off and nothing is running.
I'm going to piggyback this forum as I have been searching over 40 min and this looks closest. Sorry ahead of time.
I also found it takes forever to chafe my nook. I have a droid raze and ourchase local for it so I'm using in my nook to shutbdown the wifi from 1am to 6.am. hmm I may change that to. 12:69 am. It will help with my issue but I still have the the following request.
Wifi seems to be eating up battery life. Does anyone know of a program that will auto off wifi if not used for say at min?
Also for other readers: I found a simple free program called connections (for the bionic connectivity issues) I use it on the nook when there seems to be an issue. I have a shortcut in app launcher so its avail in any program.
Any feedback welcome.

No, but if you leave the defaults, then wifi should be off while sleeping.
Or you can use the status bar pull-down in CM7 to turn it off when you are not using it.
However, I find that it doesn't make a huge difference.

I am using Juice Defender Ultimate on my NC running rooted B&N 1.4.1 for exactly this purpose, and it is working well. I also tried Green Power, but had problems with it.
JD is definitely overkill, since it's meant for device with more radios. You could also use Tasker and set it up to turn off wifi when the screen goes off.

Help! Screen killing battery.

Thought I'd ask the experts in all things Glacier...
A couple of weeks ago I found that my phone wasn't charging as quickly as normal. One night I plugged it in, got up 5 hours later and found it had only charged 50%. I left it plugged in a few more hours, and everything seemed ok, but I didn't use the phone much. Then this started happening consistently, and with the screen brightness set anything past 1/3, I was literally losing 2% per minute. The display appears to be the big drain - nothing else really even registers.
So I ordered a replacement battery, ran it dead and recharged twice, and I'm still having the same problem.
So the question is, with the battery now eliminated as the problem, is it possible my Rom is causing some screen glitch (turning on at random times?), or has my phone decided that it's been dropped in too many times and it has some internal damage that's causing the screen to draw more power than it should?
Related question, how does one restore darkside sense 4 Rom? Is out the same procedure as stock roms?

Have you tried another rom? Or maybe reflashing? It might also be a good idea to re-calibrate your battery to make sure you aren't getting wrong readings of your battery.

Thanks for the suggestion. The new battery isn't OEM, so a calibration might be in order. I downloaded an app and I'll try it out later today when I can charge my phone back to 100%.

The battstats.bin file that is deleted when "calibrating" the battery is located in /data. That said, just flashing a ROM wipes this file. Just make sure you flash on a full charge and all is well.
Be aware that there are several items that can be the culprit in the scenario. The charger, cable, port, charging circuitry and battery are all part of this setup. Try to swap out as many of these items as you can until you narrow it down, if reflashing doesn't help.

I'm a little confused about how some of those would factor in.
The drain only happens when the screen is on, and the brightness is turned up beyond about 25%.
It's not that the phone won't charge, its that it does it slowly, and the display is using waaay more power than it should be.
Screen off=1%/h battery drain.
Screen on lowest brightness=20%/h
Screen on highest brightness=120%/h
Although the problem might be resolved now. I have the screen set to max and my charge hasn't started at all while I've been typing this out.
Guess I'll see hours the day goes, but it would appear that the battery calibration did the trick.
*EDIT*
Nope. Still draining too fast. According to the battery drain app, I'm still losing 120%/h on a higher brightness setting.
Time to back up my apps and try reflashing my Rom I guess...
This sucks.

Update: Tried my wife's battery in my phone, same crazy drain, so that excludes the battery for sure.
Did a restore, unfortunately got stupid and only backed up my downloaded apps, so 36 updates later and one manual genius button apk install and I'm back to where I was minus a few notepad notes...
Battery use still seemed high at first, but I think it was swapping the batteries around with two different charge levels that threw off the tracking. I actually seem to be back to normal now. Battery use is nowhere near what it was, even on a medium brightness setting.
Conclusion: Glitch in the OS. Restore did the trick.
Thanks to all for the assistance. Hopefully this helps someone else down the road.
Edit: Spoke too soon. Issue continues. Has to be the phone itself at this point.
Sad... I liked this phone.
Oh well, I guess I have an excuse to buy an Amaze now. Thanks again for the suggestions.

Btw. I believe I have answered the question on how many times you can get away with dropping this phone: 11.
