      • 15. Re: NT: Battery life?  How is it?

        Just for S&Gs while sitting at work today, I decided to see how the battery would hold up while streaming via Netflix. My NT is brand new out of the box as of yesterday afternoon, and has only been charged once (overnight last night), so it still needs to go through a couple of charge cycles to reach optimum performance (based on previous experience with lithium battery-powered devices).

         

        I selected a 45-minute episode of the original Star Trek series (The Corbomite Maneuver for any other Trek fans out there who might have been curious); was connected to wifi via a Verizon LTE mifi device. I have the screen set to about 25% brightness and power save mode is turned on.. Battery was at 99% when I opened Netflix and started the episode.

         

        I set the NT aside and worked while it ran, but checked on it three times during playback. Each time I checked the battery life it paused the show, which I would then have to start again. All in all the screen was probably on for about 48 minutes from start to finish. The video was fluid; looked crisp and very nice, even at a low brightness.


        When the test concluded after I closed Netflix, I had 88% battery life. Not bad at all, IMO, especially for such a small and thin device.

         

        Not scientific by any means, but thought that some people might be interested in hearing about it. It will certainly only get (marignally) better with a few charge/discharge cycles. :-)

         

        EDIT: BTW, I do not currently have an SD card inserted. I have no need for one as of yet.

          How are your Nooks doing in sleep mode after a couple weeks? Because my NT seems weird. I had great battery life in sleep mode for the first couple weeks. It would lose 1% or 0% when I had it in sleep mode over night. Then, after about two weeks, it started to lose 5% over night, and then 10%. Now I'll walk away from it for a few hours, come back, and it will have lost 7% in sleep mode with wifi off. 


          Keep in mind that the battery gauge on most of these devices is only moderately accurate. For some reason, if I track usage on an hour-by-hour basis on mine, I get a 10% drop when I hit roughly 70% and another at 30%. Mind you, my actual battery life is still good overall. The gauge is just off. I once streamed audio for 3 hours on a device that was indicating I had 1% charge left.

           

          In other words: I'd only stress about it if you're actually seeing less battery life than you expected, whether in actual usage, or in standby. If you're getting weeks out of it, I'd say you're doing well!

            Thanks for all of the suggestions. My battery life is back to normal. Does anyone else have the Quickoffice Pro app? I suspect it was that app draining my battery life in sleep mode. I let my battery drain to 15%, unarchived and rearchived the Quickoffice app, shut down and restarted my NT, and then charged it back to 100%. It's been fine ever since.

             

            Also, no, I haven't used a microSD card in it yet.

             

            When sleep mode was giving me trouble, I had to charge every two days. Now I'm squeezing four days out of each charge with lots of reading and some light internet surfing. I haven't watched video on it yet.

            • 18. Battery life for tablet

              my battery is way worse then the nook color.  I have to recharge it every other day.  I only use it for maybe 20min at a time x2 or three times a day and the battery is weaker and weaker.  from 100% in the morning, 20min use, to 49% in the evening and then again 20min use and by morning i only have 20% left.... I'm very disappointment.  I sold my nook color and I wish i had it back.

              • 19. Re: NT: Battery life?  How is it?

                I'm having the same problem.  My battery is discharging way too quickly in sleep mode.  When I put it down for the night Wednesday night it was at 54% battery left-- the next evening I picked it up to read it & it was totally dead.  Wouldn't even let me turn it on until I charged it.  It had been asleep that whole time, less than 24 hrs.  Wifi wasn't on either.  It was not like this when I first brought it home.  It's gotten increasingly worse the last few weeks. 

                • 20. Re: NT: Battery life?  How is it?

                  Late to the party, but SO glad to read all the posts.  I have been having a HUGE problem with the battery draining while my 1 week old tablet is in sleep mode (WITH wi-fi off and pwer-save on!)  I've been having to re-charge on a DAILY basis, even when I only get to use it for a couple of hours.  It was at 100% charge when I went to bed last night, and at 70% when I woke up this morning.  Customer service tells me that this is not a problem that they hear about, which had me thinking it was me!  I have actually swapped it for a new one (because the guy in the store didn't know what else to do), and done a factory re-start because the woman on the phone didn't know what else to do (which means that I had to re-load all my books, apps, etc THREE times - lots of books because I had the first edition).  Should have checked in with y'all first!  I did have a scandisc chip in because I thought I had to in order to side-load docs and photos.  It is now out, and I will see how the charge does.  Hopefully I will have the success you mention.

                  Thanks.

                  • 21. Re: NT: Battery life?  How is it?

                    I must be living right. I recharged on Friday, turned the wifi on to check out the Free Friday book and let any magazines/apps update. I normally turn the wifi off after doing that. 

                    I just checked after reading about the problems some people are having. Turns out I didn't turn off the wifi so my NT has been on standby with the wifi on since Friday morning. The battery is at 95%. I guess my point is, if you have more lose than that just on standby and the wifi turned off, there may be a problem.

                    BTW, on the app side, I don't have Words with friends, I do have Lost City (no exit button), Taptu, all my emails linked in, and not a lot else that could be a problem. I do have a small SD card installed.

                    I am sorry other people have problems. I really like my NT. It is the only mobile that I have and I really like being able to have it with me.

                      There is ... something ... that triggers the problem, but I just can't narrow it down. 4 times out of 5, my Tablet is ready to go when I turn it on. That fifth time, though, it's completely dead. I use only four applications, Reading, Hulu, Netflix, and ezPDF, but it isn't like I can say "I run X and then it dies". That's the frustrating part: the conditions are so unknown, and I hate not being able to read when I want to.

                       

                      The solution is to reboot the device every time I'm done reading for a while, but then it doesn't feel like a quality product to me and I resent the purchase.

                       

                      If it wasn't for the Nook reading software being the best out there at the moment (not that it's perfect), then I'd have ditched it by now for a Galaxy Tab Plus where I can at least diagnose and correct the sleeping issue.
