NC battery life - Nook Color Q&A, Help & Troubleshooting

How long can we expect the internal battery of the NC to last? And when it gives up the ghost, is there a procedure to replace it?

Got mine as a refurbish a year ago and my battery is still going strong... You can rely on the nooks battery to last you for a while.

Been using mine for over a year and the battery life has actually gotten better with an ICS install. You can replace the battery yourself, hoever, it's not an easy procedure. You have to unscrew and take apart the device. Barnes and Noble will replace the battery for you for a fee.

On a normal day of use, how long does everyone's battery last? I usually have to recharge every night if not every other. It seems without even touching it for an hour or 2 it will lose around 5% battery power.

Yes, I agree. CM7 seems to suck out more. I used my sweetheart/wife's NC to sideload some apps 1.3 doesn't see and she berated me for using up her battery!

You will see a significant difference if you have active widgets, apps doing background polling and using wake locks with the screen off.
With a load of active widgets and polling, 5% per hour sounds about right. Up until yesterday, I'd tried to minimize background activity, so had no facebook or other background activity except for Enhanced Email polling every hour. I saw a drop of about 2% per hour when not in use. I've since disabled even that polling, and now it stays flat for 4-5 hours before I see a drop.
With screen and wifi on, with screen brightness at 25% or lower, I usually see a drop of 10% per hour, no matter what I do.
This is all very unscientific, of course, and subject to the accuracy of a notoriously inaccurate software gauge. It's also varies significantly, depending on what firmware you run, and how you use your device. If I'm on it intensively, I can get an 8-10 hour day out of it before recharging. Usually, I'm good for 2 with casual usage running rooted B&N 1.4.1.

Worst battery life ever

was today with:
2.6.35.4_SVS-925mV_BFS_AXI_720p_1113MHz_082710
and
update-cm-6.0.0-N1-signed.zip
with phone idling all day, battery went dead and phone shut off within 8 hours of full charge... wtf?!?

I've also noticed that with the latest CM's battery life is an issue for me. Ive got KoR roms to last almost two full days but cm is dead within 20 hours.
My battery life has changed as well and I now have to keep my travel charger and car charger with me at all times or suffer with a dead phone.
i had been running rc3 with the 8-19 kernel, and my battery life was similar to stock, but the combination of latest CM and wildmonks are just killing me... i think im going to go back to rc3 with the 8-19 kernel.
Check the active processes. You can't drain the battery in 8 hours unless you have a process stuck, using 100% CPU constantly (possibly Exchange?).
good thought, but im not an exchange user... i cant seem to isolate the issue. im going to do a full wipe and try stock to see if maybe i have a bad battery.
People with battery life issues should try Enom's ROM with a wildmonks kernel. I'm 18 hours in of a full charge and I'm at 76%. That's normal use with full screen brightness, wifi and gps, quite a few background updating apps, etc.
Over 50% of power usage should be the display under even moderate usage.
With wifi, push, and poll active, the battery drop per hour with the screen off should be less than 1%.
If it's higher than that, you need to find the rogue process or get rid of an automatic task killer.

Display is most of my usage with over 50% every time. I have one app that auto updates in the background, Twitter, and thats every half hour. I do have 3g on but with wireless on most of the time. GPS, Autosync, and Auto-Brightness is on. I play one game twice a day, World War, once in the morning, once at night, but both times are usually on the charger.
Now that I think about it, Im a part of latitude but maps/latitude never consume battery according the about>battery.
Either way CM6 full charge starting at 4am, with light-moderate use, will be dead at like 5pm. I can go almost 2 days on a single charge of KoR rom. Enoms rom I have tried and lasts a full day +some...

I have the same issue and have had it since RC2. I can deal with it since I have the desktop dock at work, the car dock, and two wall chargers at home. The drain is pretty noticeable -- after about 30 minutes of the phone being off the charger and left alone with screen off, the battery charge is at 94% with "Display" using 65% of that. Wifi/BT/GPS off.
Like I said, it's not a big deal right now because I have chargers everywhere, but it's really annoying. I'm still searching for the fix, but if I can't find it, back to MCR for me.
I tried CM for 1 week and I must say the extra glitters is not worth the poor battery life., only lasted 1 day if used moderately. I just switched back to FRF91 Stock Rom today, lasts me 2days if used moderately. Longivity of the battery is another long term concern people should think about. I still miss my modded dialpad with big buttons, cool trackball colors and many more, CM is such a TEASE!
What kind of battery life are people getting with Pershoot's latest? It's undervolted, so it should do pretty well.

Tried Enom? I've seen zero difference in battery life, perhaps slightly better, since switching to it from stock Froyo on my N1.
In the battery use screen, what's draining the battery with the screen off? Let the phone drain like 10% with the screen off the entire time after unplugging.
several recent nighties and cm6.0.0 seem to have something broken.. Four hours of standby after full charge and the battery level already @ 83%.
cell standby 32%; idle 29%; display (wtf was turned off all the time) 28%.
Drains twice as fast compared to older CM roms..
The LEDs are also considered the Display by the battery meter.
Still, 17% in four hours is enormous. I guess I'll have to hold off on CM6 until they sort this out.
Dicks! 4% battery drain in one hour with almost no use, and that's after flashing pershoot's undervolted kernel. No way.
I'm going to try wildmonk's kernel now. :/

Your battery life so far?

At the moment it seems like I'm getting around 5 minutes per percent (around 8 hours of constant use). The weird thing is that seems to be the case across all use, I get the same results from web browsing as I do reading comics in airplane mode.

I get pretty incredible standby though with set cpu. I'll go to work and come back after eight hours or more with one or two percent gone.
Yeah the standby life is amazing
Sent from my Samsung Fascinate via Tapatalk
set cpu app helped me get amazing stand by times. i mean i lose 1% every 24 hours propably.
during normal use, i get average 4-6 hours. surfing youtube, downloading, playing games. usually 5 is about right. People who say they get 8-10 hours heavy use are on one.
I would agree with 4-6 hours with constant use such as reading or twitter browsing. I previously had a Nook Color with CM7 on it and got about the same. Standby is amazing I almost never turn it off.
After about an hour of surfing or playing a game I lose about 20% so about 5 hours. But when watching videos I get around 7 or 8 hours

This sounds awesome I just got 48 hrs on included 4--5 hrs of use. Down to 2% ... wifi is set to go off with screen (after 1 min) not. Sure wat else to change
Hmmm. I was hoping that rooting/SetCPU/screen settings could get me closer to 8 hours of life, but that's not the case. I'll probably just sell the Iconia since the battery life is my main reason for owning a tablet, and in this case it isn't that much better than my laptop.
Run time.
52 hrs. %79 & moderate use. Never shut it off & still testing. Want to see how long it can go until I reach %30.
not trying to be an ass, but what are you guys using your tabs for? i run taboonay rom with thor kernel and good to very good battery life. I use my tablet all day long at work for e-mails, pdf viewing, gaming when i shouldn't be, and playing around on the internet. I wake up at 5 am everyday unplug my tab and start the day. With said usage i can go from 6ish AM till almost midnight and still have 20-30 something percent battery left. I wouldn't say i use it hard core, but i put it work. Just charge it while your asleep and it should last all day. Now on the occasion i watch movies on it it does drain the battery like a bastard but i can still get 5-7 hours of non stop movie watching on it. I really can't complain about the iconias battery at all. If you expect this thing to run like Carl Louis all day long without plugging it in you're in lala land. Theres alot of threads on how to get rid of cell usage drain, and look at whats killing your battery it may be an app or something you did settings wise to drain it faster.

Completely agree, I got mine on Saturday and apart from the initial charge it's only been plugged in twice. Used on and off throughout the day on Sunday, most of Monday evening, all Tuesday evening and all Wednesday evening, playing games and on the web with a bit of youtube and playing around. First time charged at 35% on Monday evening, second time yesterday at about 11pm as it was down to 10%. I think that's pretty damn good myself. It's on OTA 3.1 and Rooted
As for comparing to netbooks, have a look at the size of the battery in a Netbook compared to the Iconia. Of course they're going to last similar amounts of time - The Iconia has a smaller battery but has less to power versus the netbooks larger battery with more devices to power.
I'm at 67% after about 27 hours with about 2 hours of actual use. I guess that's ok. I flashed the Minimalist rom on Tuesday so I probably haven't given the battery enough time to break in. Sorry for being a *****, I'm just impatient >.<
I was kind of afraid if it would last me through a day of classes when college starts back, but I think I'll be ok.
I was getting around 5 days total with 1 to 2 hours display usage before the update to 3.1. Now it only goes 2 days when on standby with less than an hour of usage. Going to download SetCPU and try that. I have not changed anything (widgets) since before the update, so I have no idea what's eating up the battery.
Does anyone use there tablet in this post?Lol
I use my tab all-day long and I usually have 20% by the end of the day.

I use my tablet about 4 hours a day
I have to charge every 2 days
I charge during 2H30 arround.
Mine has been doing pretty well lately. I guess flashing roms took its toll

setcpu settings?
I'm using SetCPU as well, but getting no where near what you say. I left it on sleep last night and it drained 15% - same as before.
But, maybe I'm not using it right. I enabled the "screen off" profile and dropped the speed.
What are you doing/setting to get that standby time?

Ok, I activated a couple more profiles including "time", temp, low battery. Low battery definitely turned on and I saw the change in the icon on the bottom right. I think the "screen off" is not turning on - basically can't see it when the screen is really off . But, it's definitely draining the same amount of battery.
Am I doing something wrong?

SetCPU didn't help mine either. Tried a few different profiles. I thought the one that would help the most is Screen Off, I set it max and min to 216mhz. No difference in battery drain overnight.

[DISCUSS] Battery Life.

Most threads about battery are quite outdated, so I decided to start a new one.
And so recently my battery is starting to get less muscular.. My Xperia Play is 4 and a half months old, and one hour of consistent 3G usage can drop the battery down from 65% to 24%. I'm not very sure whether that is the norm, but if it is, that's bad battery life, in my opinion.
The Android 'Battery Use' page shows that most of my battery is drained from Cell Standby and System Idle (30%).
My wireless and GPS is always off. Am on 2.3.4 rooted.
Also, Gameboid consumes battery like a beast (even more than 3G), but I guess that's due to the high processing power required for emulation..
Is there any way I can improve the battery life?
Personally I found battery life to be terrible on 2.3.4 so I downgraded to R800i_4.0.A.2.368_World. I'm running 122M-1.5Ghz with scary and BFQ, on top of that I undervolted every frequency as much as I could using incredicontrol (Id give you the values but they vary by device). I always leave wifi, bluetooth, gps and data off when not using them, turned off automatic clock updates (there was a battery draining bug with this a while ago) and I run at 10% brightness with autobrightness off. With this set up I lose maybe 3-5% per night, so for around 6-8hrs in standby while I sleep. Ive got similar results on both cyanogen and stock. That being said I don't have a data plan so I do save a lot by not having data on, but a 40% drop in an hour isn't normal - Ive played an N64 emu which runs the processor full speed for that long and only experienced a 15-20% drop.
imho, the best battery life i've experienced is on 2.3.4.. when i'm on 2.3.3 i always lost 30-40% overnight (wifi, bluetooth, 3g, etc are turned off) stock rom, locked BL..
According to some folks, if you're charging your phone and let it stay plugged in for a while after it hits 100% that screws with the battery life.
On 2.3.4 rooted with all the facebook, timescape and other bloat removed my battery is pretty good. Wifi is on 247 and it reverts to hspda when out. Data syncs hourly, and i have contacts, hotmail and gmail syncing.
The other day i was sitting at 57% after 1 day 3 hours, and that included a half hour go on fpse, might have been more.
Battery life seems good to me. I get 1 day usage then charge over night. I do use my phone quite a lot for this (Tapatalk), Phandroid app, Engadget app, Joystiq app and browser. Wifi and GPS is always on.
At a guess I'm using the phone for about 1 hour a time, about 7 times a day... So like 7 hours web use, phone calls and texts, syncing is set to every hour with FiX on.
When I was on 2.3.3 I'd be lucky to get 10 hours out of the battery but 2.3.4 is awesome.
Edit. Obviously I play games too. Forgot to mention that.

Actually I get similar idle battery drain rates as you, but personally I'm not very concerned with battery drain as long as it's not so much. I'm more troubled with battery life on consistent usage, which I feel the Xperia Play (or at least mine) sucks at.
When I play Gameboid, I get the same fast battery drop too - 40-50% in one hour.

Yep, I read that from a lot of places too. I admit I used to do that (and have since stopped doing that), but sometimes I can't help it if I forgot to charge at night before I sleep (and have to charge overnight to ensure I have battery the next day).

I envy your battery life One thing, if you remove Facebook, will your Facebook contacts picture sync go away too?
And did you remove the bloat stuff by deleting them from /system/app?

Sigh, I could never get such good battery life..
All the more reason to undervolt, in standby undervolting doesn't have much of an effect on the phone since the processor is either in deep sleep or running at its lowest speed. Also using a governer like scary or smartass helps keep your device running at a lower frequency when possible. Like I said 2.3.4 was terrible for me, 10% drain overnight or more, but apparently YMMV with this. That being said 40-50% drain in an hour is crazy no matter what you're doing on the phone, like I said running N64oid for an hour drops me 15-20% keeping in mind this is at 1.5GHz with sound and the backlight constantly on. If all else fails you can always wipe everything and start fresh, carrying over the same settings while jumping around firmware can lead to some undesirable results. Anyway good luck and keep us posted
The facebook sync option doesn't appear on my anymore, although it used to. To clean it up all i did was :
Purchase Titanium Bakup
Freeze the things I wanted to remove and test rebooting, only freezing a few more each time
Backed up every app
Slowly uninstalled each one with a reboot every couple of apps
Enjoyed my faster phone with better battery life
I use the gmail sync and life.contacts for contact pics
I get amazing battery life on 2.3.4.
In stand-by I lose 1% every 3'rd hours. It's very good in use too. Yesterday I had my day with heaviest use so far and texted like crazy the whole day and a lot of phone calls. Some surfing, gaming and updating of apps between that. Basically the phone was frequently used the whole day with short periods of stand-by in between. At night when I went to bed the battery was at 40%.
Earlier this week I used it minimally for 2 days. The battery dropped 10% for each of those days. But that was very minimal use.
So in short. I have not experiences better battery life on any other Android phone. What takes the most power is emulating. It can suck up like 20% in an hour depending on which emulator I use.
I got my Play at the beginning of the week and with quite intensive use, without WiFi or 3g, I scraped an 8am to 6pmish day on the battery. Admittedly with a fair bit of gaming.
However, that was only waiting for my 2600mAh battery to arrive and now I'm using it, I would recommend it for the bulk. You don't notice it after half an hour or so and I have no issues with gaming on the go whereas I always thought it may die on the stock.
mine drops 4 - 5% /hour..... much faster than b4.... dn no w is goin on w/ ma PLAY.....
I found that since updating to 2.3.4 my battery drains quicker. Usually charge overnight and battery would be around 15% bedtime. (7am - 11pm approximately)
Now I'm finding that by 6pm I'm having to charge it and that's without gaming
brought to you by the XDA app on my badass Android toy
Three times in my first week and a half of ownership I awoke to find it completely dead despite fully charging it or nearly fully charging it before bed. I usually sleep with my phone next to my head so that I can ensure that the alarm will wake me up. That and the lack of a timer function really irk me about this phone. I really hate having to create and save an alarm when I know I only have 45 minutes or 2 hours to sleep (I work a grave shift and have inconsistent sleep schedules during the day). It adds insult to injury when something changes that lets me get another 5, 10, 20 minutes or so and I can't easily add it. On top of that, I have to go back and delete all the alarms I made throughout the day!

Thats crap. Infact you should leave your phone plugged in a good 30/45 mins after it says fully charged if you want a full charge

Not at true max but at what the battery controller considers max. True maximum will drastically decrease the total cycles just like true minimum only to gain longer cycles in the short-term. When you store a battery it's best to stop at 75-80% because it will lose stored energy slower and not spend nearly as much time near 100%, which is still a trade-off between long cycles and more cycles.
What do you guys think to this?

(Please add the WWW)
Its the same size as the standard stock battery so there's no extra bulk... But gives an extra 930mah?
To be honest, I am somewhat tempted... However the question is, will it explode in my pocket and result in me losing half my leg? It's quite a big risk to take! There also might be a voltage difference, however I cannot see anything on that.
Im currently on 1.6Ghz, undervolted. And I just played Order and Chaos for 35 minutes and went from 86% to 63% - I've had bad luck in the past regarding phone batteries, I remember replacing my G1 battery around 7 times, but at these rates my Play would be dead after around 3 hours or less of gaming.
how do you update to 2.3.4 it wont show me =[ please someone answer me :/

You have to expect that with any phone playing an online game. Wifi/screen/GPU/CPU are going at full wack at the same time. What dya expect?

[Q] How often do you charge your simple touch

How often do you charge your rooted nook simple touch? after i rooted mine after reading on it for about 6 hours for 2 days, my battery dropped to about 78%. Is this normal or my battery draining too fast? also when nook goes to sleep mode it doesnt drain battery right?
It kinda depends on if I'm using it a lot during school. If I have the WiFi enabled and I'm taking notes with a lot of screen refreshes, then it ends up at about 50-70% battery at the end of the day, at which point I either charge it that night or the next. Other times when I don't use it for much other than writing down homework, it doesn't go down too much. I haven't charged mine for a few days and it's at 40% right now.
I don't charge mine all that often depends on just what I'm doing with it. If it's got wifi on it's a couple of days, if I'm just reading or not using it it's a lot longer. I intend to eventually do a battery test of not using it, using it without wifi, and using with wifi, but it could be months before it gets finished (or started) since I don't have multiple nooks. lol
I've only done testing for 10 hour stints, but here's what I've noticed:
With wifi off and the unit mostly sleeping, it uses about 0.14% battery per hour.
With wifi on and the unit mostly sleeping, it uses about 0.9% battery per hour.
With the wifi on and using the unit furiously, it uses about 8% battery per hour.
I haven't had the unit long enough to develop any "typical" daily patterns yet. I did set up Tasker to only turn on wifi when select apps are run, and shut it back off when they close. This seems to give me the best of both worlds.
So to answer the question, I charge it when it gets low (< 30%). How long that takes varies based on usage.
It seems you all are lucky. I am using my nook the same way as bobstro, and I have had my nook for 3 days. I charged it completely. After reading for 4 hours max, and playing with android for 1 hour, I am at 30 - 40%. What is going on?

It seems you all are lucky. I am using my nook the same way as bobstro, and I have had my nook for 3 days. I charged it completely. After reading for 4 hours max, and playing with android for 1 hour, I am at 30 - 40%. What is going on?

A lot depends on how many screen refreshes you're doing, and network/wifi usage. If you're rebooting a lot, and raiding the Market, it will go more quickly.
Try just letting it sit unmolested for a bit and see if it levels out. With wifi off, mine is barely sipping power when in standby.
You also could be seeing bogus calibration. It's not dead until it's dead, regardless of what the gauge says. I've had Android devices blasting audio for 3 hours when the gauge read 1%. I'd give it a few more days and charge cycles before worrying too much. I think many of us panic when our battery doesn't last long the first few days, forgetting that we're playing with it constantly.
Of course, if you're still seeing poor battery life after a few days, definitely take it in for an exchange!
Ok. I charged it to 100% last night and then turned it off when it completed. This morning, I turned it on, and it has been on for a total of 4 hours. 2 of these hours were in standby, a half was reading, and the rest were taking notes and chatting with friends. Two hours were spent with the wifi on and two were spent with the wifi off. It is at 90% now. I think the part about misreading the level is what happened to me.
On a related note, anyone know of a good battery monitor widget for ADW?

When I'm in compulsive battery tracking mode, I use Battery Monitor Widget Pro ($) for the graphing features. It allows me to go back and compare a week's worth of battery performance data. I also get a good feeling when I glance at it and battery availability has been flat for an extended period.
There's a free version, but I don't recall how useful it was.
Once I'm comfortable with things, I plan on removing it and any other monitoring tools, as they do consume some battery themselves.
Thanks. Will have to check that out.

Do I Have a Battery Problem?

I have had my Note for 9 days now and wonder if my battery may have an issue. Yes the phone is entering deep sleep, No I don't have any specific app that is running it dry. Screen takes most of the juice. I have it set at automatic brightness. Everything is off. It does auto sync. Signal is fantastic. I can hardly get 3/4ths of a day. I usually spend 30 minutes on the phone. 30 emails, 2 hours browsing, 30 minutes on tapatalk. This has always been my pattern and coming from a Motorola photon I always made the day easily. I'm on ISC (stock) not rooted just plain old stock. I'm thinking maybe a battery problem? What do you all think? Thanks for your help.

I've only had my note a couple days. I've gotten about 10-12 hours out of it both days. But that was with what I would call moderate to less then moderate usage. A little web browsing and facebook, probably less then 2 hours total. Maybe 20-30 texts and reading emails for maybe 30 minutes and 10-15 minutes of calls. I'm not sure what to expect, I am coming from a rooted HTC evo which I ran a lot of custom roms/kernels on, so I got great battery life with it. But I don't remember how it performed stock. The Note gets me through my work day, but not much more.
Charge the battery to full.
Let it drain completely (till it turns itself off).
Charge the battery to full once more.
I don't know the science behind it, nor does everyone benefit from doing this. (Something to do with calibration of the battery) but I do this after every major update, or new phone. I'm currently sat on 44% battery after 24hours usage (Moderate, certainly not heavy usage).
You have to remember the note will consume a large amount of battery simply because of its screen size (As you've noted its the biggest offender).
Someone with more experience/knowledge will hopefully be along shortly to give you better more informed advice but this is what I know from experience.
Normally what I have seen is I get approx near
4 hours of battery life (screen on time)

Batterylife on samsung ics (XXLPY) is terrible if you compare it to gingerbread. It is nearly cut down in half. I guess touchwizz has gotten more hungry than before or samsung has altered ics so much that the advantages are gone.

I do this method every 2 or 3 months on all my devices (iPod, phone, Laptop) so that the percentage or battery shown on the devices is more accurate. I read somewhere that since most of us charge out devices before battery dies completely, like we charge it when its 80 or 60 or even 20 instead of charging it when it completely dies, doing so makes the accuracy of the percentage very low but we can't help it but to charge it at what ever percentage for various reason thus, I always drain all my battery on devices completely than charge it full before using (minus the first full charging). Any ways if your ICS it seems to be a bug, it cannot be fixed until a new update.

Do the charge/drain cycle.
I've done this and improved the battery life immensely.
Currently my note has been on for 3d 21h 16m 1s and has 11% charge left - okay so it hasn't been used much over the weekend but that not a bad standby time.
