Jetbook vs Libre vs Sony Battery Life -- help?
Hi folks, I'm obviously a newbie testing these waters. Read all the reviews, watched the youtube vids, had a Libre in my hands and the Sony PRS300 and 600.
But NOTHING really addresses the issue of hands-on experience with battery life. And whats the diff with Page Turns vs Hours ? (A device could be on for hours and have an unrelated number of turns, right?) Some pages say 24 Hours for Jetbook / Libre, some say it equals the 7500-8000 Page Turns of Sony. But I read I think in here someone said ONLY 600 Page Turns on their Jetbook !!? So--- Could folks chime in with Personal Experience for *BATTERY LIFE* and if you know,,, how it compares between these models: *JETBOOK *ALURATEK LIBRE *JETBOOK LITE *SONY PRS-300 (not really interested, but curious now...) I can only afford to purchase one, once. Supply here is Aluratek from Costco ($169), or the Sony ($199), but I don't mind going ebay for a Jetbook ($150) or Lite ($130) ANYWAY... PLEASE HELP.... been at this for DAYS ! Kindest Regards, James (one more post to come...) |

Hi James,
I have both units - jetBook and jetBook-lite. I can recommend jetBook-Lite because it works with AA - replaceable batteries. I charge AA batteries one time per week and read 3-4 hours per day. You can find many positive reviews about this model on NewEgg.com. They sell it for $129.99 and don't charge sales tax if you are not in CA,TN or NJ. |

Using your numbers... assuming you take 2 minutes to read a page and you have 24 hours of battery that would put you at around 720 'page turns' per charge. My personal experience is I eventually need to sleep even on days of marathon reading so plugging in my jetBook isn't an issue (and it is worth it to me for the trade off in faster response time, lack of refresh 'flash', and lower price.) You can also continue to read the jetBook original while you have it plugged in to either the wall socket or a computer USB. Don't forget that DRM support for the jetBook Lite is limited at this point and non-existent in the original JB if you plan to buy lots of new releases. |

I don't have it handy at the moment to test it, but I noticed that when I plug in the Libre to the AC outlet when it's turned off, the screen that pops up is the battery charge one. But one time I plugged it by accident with it still on, and the screen stayed on the book page, so perhaps you can.

I just got a libre, charged it. I read about 45 minutes daily and the device stays on its sleep phase (the one that opens up right away when you push the power button, so its not really off) and after 12 days only the last bar (out of three) is still lit. Battery will not be dead for a while but I just decide to charge it then (3 hours) since I heard that you can get some funky things happen if you let the battery die completely out). Hope this helps.

WOW, that's really short battery
Which is the same as another I read. More like 5-6 hours, not 20-24 8( |

Now please the other more knowledgeable members of the forum correct me if I am wrong. But as artifact explained, the libre/jetbook will draw down power even if you are not reading it just because it is not really off, but in sleep mode. So the correct count would be perhaps 9 hours active reading and the other 11 1/2 days in sleep mode (and I am sure it would have gone several more days on the remaining charge). Now if you read straight, you may get 20 hours or so, I don't know.
It's not a bother at all for me since I don't live in a cave or anywhere that there won't be power available for a 3 hr recharge and even if I did go on safari there are also ipod external power sources that hold enough power to charge the libre three times over. I don't think I have vacation leave that will last that long! |

Yeah, I don't see why battery life is an issue, unless one lives in a cave and the nearest power outlet is a hundred miles away. But if power is a big deal, I guess the best device is the Jetbook Lite. Charge a couple extra battery sets for backup and you will have uninterrupted read for weeks.
I only have 2 batteries sets for my Jetbook Lite. Once one battery set is drained, I just pop them out, put in the other set, charge the dead batts and continue reading. And the cycle continues... |

My Libre, with software version 0.15k patch v15, does allow full operation, including reading, while it is charging. When first plugged in, the charging screen comes up but pressing the power button switches it to normal operation.

On my wifes Jetbook she reads with it all the time as she's charging. If I try to do that with mine, funky things happen. Have seen it get "stuck" had to reset, reboot, etc.
So I just read with it till its down to one bar, then charge it. The only problem I have is if I have a really good book or series of books, I can go through a charge in 2 days and still be a few hours short of bedtime when I hook it up to the charger. Worst case scenario I have to go do something else for a couple hours while my book is charging. |
