You can try doing what I did--turn airplane off and wifi on and leave it like that. It worked for me.

Re: Post Your Battery Experiences

I am right there with you Princess. I'm not happy either. Listen, I want Barnes and Noble to succeed over Amazon, and thats why I made a conscience choice to pick hte Nook over the Kindle. But apparently the Kindle 2 battery is FAR superior to the Nook. Their website claims 2 weeks between recharge times and from what I'm reading on the user boards, real world people are getting close to this.

 

If B&N says the Nook should be getting 10 days of reading , with airplane mode on, then it should. Shouldnt not matter how many pages you are turning. This thing is supposed to use minimal power in both sleep and on modes, if wireless is off. Even 7 days would be acceptable, but people claiming 2-5 days, when they are reading 3 hrs a night? That is unacceptable. I still wonder just how B&N is explaining this? They need to come out and explain how they got 10 days, and why their experience is literally twice the amount that others are experiencing. I like the nook and want B*N to beat out Amazon...but this really is false advertising on their part.

 

My only hope is that when the batteries on these units die out ( 2 yrs maybe?), the newer batteries will be far better. Another possible hope is future software revisions, that may extend battery life somehow. But i have a bad feeling that all of us who already own the nook , are pretty much out of luck, and will have to deal with 3-5 day battery life depending on our reading habits. Thats a far way off from 10 days, and very misleading of B&N literature.

 

By the way, just got to the end of Chapter 23 of Amy Tan book "100 Secret Senses" and the chapter ends abruptly, with text missing! Have to go to book store to actually finish the chapter. Another e-book glitch. Ah, perhaps paper books is the way to go :smileysad:  ( I wonder how i report the missing text issue of the e-book to barnes and noble? I'll have to track that down now. Hopefully can get a refund on that book).

Re: Post Your Battery Experiences

Thank you  Darren , this is frustrating I am so a Barnes & Noble fan but I am losing my pom-poms . I did not research this item as well as I should. Now that I am it is somewhat of after the fact (the fact that I already bought it). that I am researching... I have never had an e-reader and I felt Barnes and Noble would stand by their product, however, I am left LoL at me... I am currently reading "The Pillars of the Earth" and a few words have been cut off at the end of the page I have to figure out the words that are written next and move on. This is frustrating to say the least so I totally feel you in having your reading cut off... At worse, I will chalk up my loss if Barnes and Noble does not get better at supporting there products stability as well as offer more e-books. The end result will be; get a kindle  and buy books on amazon because I really love e-reading. However, I am with you I hope and want the best for us nook e-readers.  

Enjoy your journey to finnish "100 Secret Sense" by Amy Tan it sounds like a great book. 

 

And again, Thank you!

Re: Post Your Battery Experiences

Oceans, are you actually saying that with wifi ON, and airplane mode OFF, your battery life is longer?!  As much as the 10 day figure from B&N is way off, they are right about wireless modes being off, helping longer battery life. This is also the case with Ipods and all other electronic devices. If you really are getting longer battery life, from having your wifi turned on, that is quite unusual for an electronic device.

But I could see it working as Oceans reports if a software bug keeps trying and trying and trying to connect even tho the radios were all off.  A quick connect, check for updates, and go back to sleep would use way less power than trying over and over.

 

There is some evidence that the nook still wakes up and does something while sleeping with airplane mode ON.  Prove it yourself by writing down the screen saver image when you sleep your nook with airplane mode on, and come back the next morning.  You will find a different image on the screen saver.

 

I don't recall Oceans saying 10 days...

Re: Post Your Battery Experiences

Date I received the Nook - Dec 18th. Multiple charges prior to leaving the country on Dec 24th.
Date Charge completed: 01/07/2010 8AM New Zealand time
Date Tested: 01/11/2010, 7:20 AM MST
Current Capacity: 38%
Usage - Reading: ~12 hours
Usage - 3G/Wifi: Zero - in Airplane mode
Usage - Touchscreen: Couple of minutes just to hit the current reading button
Page Turns: Not sure
Font Size: Extra small
Settings: Airplane - on; Touchscreen brightness - 50%; Touchscreen timer - 30 sec
Software Version: 1.1.1
I do not put the device to sleep by hitting the power button twice (once to turn the touch screen back on, the second to sleep) rather just put it down and let it time out. I have not powered the device off since the full charge (including when on planes). Due to cross the date line, the day of the 7th was about 12 hours longer than a normal day so there is a little more idle time there.

[ Edited ]

This is my third posting/charging.  My usage numbers are approximate.

 

Date Charged: 1.5.10, 10:20 am EST

Date Tested: 1.11.10, 6:00 pm EST
Current Capacity: 4%
Usage - Reading: 30 hours
Usage - 3G/Wifi: 15 minutes (may be more; nook checked for updates regularly)
Usage - Touchscreen: 20 minutes
Page Turns: 450 (best guess)
Font Size: Extra small
Settings: Airplane - off; Wifi - on; Touchscreen brightness - 2%; Touchscreen timer - 10 min
Software Version: 1.1.1

 

I'm now charging it again and plan to keep 3G/wifi on.  I easily saw 7 days of usage with both radios enabled.  Also, nook was at my house 90% of the time and connected to my wifi network whenever necessary.  This current charging represents my fourth charge of the device since December 24 when it arrived.

@ DarrenVA , yes that is what I am saying. I do not know why nor do I know about any other devices. All I know is that I read about it somewhere and decided to try it because I was recharging every couple of days. It works for , whether or not it is supposed to do so and I also do not "put to sleep". I just lay it down when I am done and leave it alone and it does it's own thing.

 

@ icebox, I don't think that I said 10 days but it is consistently going down 10 % every 24 hours so I guess 10%=10 days.:smileyhappy:

 

I suppose you have nothing to loose by giving it a try if you are having battery issues

Re: Post Your Battery Experiences

I've had my Nook since January 14, and have charged it four (4) times. Someone on this board told me to turn off wi-fi, and put into airplane mode. This I did, and only using the nook to read, the battery lasted 3 days instead of 2.

Do I have a bad battery? If so how do I get a replacement.

I,m enjoying the Nook, but would like to be able to read longer without charging. I do not turn the Nook off! I leave it in sleep mode.

Your advise is appreciated.

Re: Post Your Battery Experiences

Initial charge: 100%. This was a pure "drain" test with airplane mode turned on. Just to see what the % drain is per hour.
My results were :
Date Charged: 1/20/2010, 8:00pm EST
Date Tested: 1/23/2010, 3:00pm EST  (67 hours in sleep mode. 0 mins reading)
Current Capacity: 60%
Usage - Reading: 0 hours
Usage - 3G/Wifi: 0 minutes
Usage - Touchscreen: 2 minutes (just to turn on each day and look at % charge)
Page Turns: 0
Font Size: Medium
Settings: Airplane - on; Touchscreen brightness - 16%; Touchscreen timer - 60 secs
Software Version: 1.1.1
So for me, it looses.59% per hour when doing NOTHING.
7 days before you loose the page you're on AND your bookmarks.
This is NOT EXPECTED because e-ink takes no voltage to hold it's last page, right? We all know there's a drain when it's alseep but for what? And this much?
I verified I had airplane mode on but I did NOT turn off wifi (I thought turning on airplane mode did that).

I'ts not exactly doing nothing.

 

Its monitoring battery charge to see if it should shutdown completely.  The only way to measure charge is to use some of the charge.

 

Its running timers to see if it should wake up to check certain things, like subscriptions, battery charge, etc.  There is evidence it does this even with airplane mode ON, because people see screen saver change with no intervention, etc.  (Probably poor programming to even set these timers when airplane is on.).

 

Some android programmers could possibly give you some more examples of what its doing in the background while "sleeping", but Linux (upon which Android is based) does quite of few system checks in the background.

 

I suspect and hope there are some basic bugs that may be cleaned up in the next release which will push it closer to the promised battery charge duration.

Re: Post Your Battery Experiences

My first post but I have been reading the boards for 2 month and haven't seen this exact problem.  I have had my nook for a couple of weeks and have been a little disappointed in the battery life.  I decided to try turning the airplane mode on to increase battery life.  I plugged in my nook overnight to charge with airplane mode on.  In the morning my battery charge had gone down a few percent.  I plugged it in again (thinking I must not have had a good connection).  The charging light came on for a few minutes, then turned off.  I left it plugged in for a while to see if the battery charge would increase.  No luck.  I plugged in to the computer and it charged fine.  I let it run down again (to 8%) and tried to charge via the wall outlook.  No luck.  The charging light turns on for a minute or two then turns off.  I tried turning off the nook and removing and reinstalling the battery.  It still won't charge through the wall outlook (yes, I tried different outlets and am plugging directly into the outlet and not an extension cord).  It will charge through the computer.  Anybody else have this problem?  Just a faulty plug on my charging cord?

I get about six hours of reading or 3 days nowhere near the ten days they talk about no big deal just stick it on the charger overnight.

Do you have a USB wall charger for any other deivce?  Iphone, Garmin, TomTom, etc?

 

Maybe your wall-wart is bad, and using another one serve as a comparison.

 

You should also try removing the battery, and with the battery still out, plugging it into the

wall charger and see if it will boot the nook.  If so, then insert the battery (with it still plugged in)

and see what the charge says in Settings.

 

I would be tempted to run that thing to Zero at least once.  Then recharge.  But of course, its important to find out if your wall charger is working right first.

Re: Post Your Battery Experiences

Ok, I know it's not data. I promise I'll post more #'s later. :smileyhappy:

 

Icebike, that's true about the CPU still doing things. I just think it's an unusual amount of drain for so little action. It's almost like they are using a "busy wait" which requires CPU (and heat) in order to do nothing.

 


TO NOOK ENGINEERS: I hope by now you see something that will help. Optimize your code to be more "event" based. You're spending too much power just to "remember" our last page and to know a button was pushed (In airplane mode, remember).  Save the current page and bookmarks on the SD-card or wherever you store the books themselves so that we're not at constant risk of loosing our place/bookmarks.

 

[Soapbox mode off. But this really has to happen -- everyone can see this problem]

Re: Post Your Battery Experiences

Icebike, thanks for the idea.  It is now plugged into the wall with my daughter's iphone USB wall charger plug.  Going on 15 minutes and it is still charging and up by 8%.  Must be a defective USB wall charger.

Re: Post Your Battery Experiences

I'm having similar issues and wrote an email to BN tech support.  I just received this response from BN tech support concerning the battery issues:

 

"This issues has been documented. Currently at this time we are experiencing some problems with the Barnes and Noble nook battery system. A software update from Barnes and Noble has been submitted to our software development team, and will be automatically downloaded to your nook. We are sorry for the inconvenience but definitely have addresses the issue and are working day and night to fix this matter."
