On another thread: https://www.mobileread.com/forums/sho...147#post817147 there is a link to a company that sells rebadged iRex units for the aviation industry, a 24 hour battery life is claimed - which in itself is far more specific than anything iRex themselves have claimed. Quite what the 24 hours amounts to though is not clear. I suspect that 24 hours of looking at aviation charts places a different demand on the battery from 24 hours of reading a text at, say, a page a minute (60 page turns per hour x 24 hours gives only 1440 page turns per charge - I'm never really sure what battery life expressed in page turns means either).
In real world use, I read for between 3 and 4 hours a day, I often flip between the things that I am reading - which presumably draws more power that just reading - when we get the firmware updates I imagine I will use annotations and scribble quite a bit, which will also impact on how much power is drawn from the battery. So I guess the real answer to the question, "What's the battery life of this reader?" is, it depends what you are doing with it. |

Question to you or others who already have the unit: can you continue to read while the DR800 is plugged in and charging? I can't with my Cybook, but can with my Kindle 2. |

Thank you, drl. That's good news. I can't count how many times I've gotten the low-battery warning on my Kindle 2 while in the middle of a novel. Being able to plug a reader in and continue to read while it charges is a big plus.

Okay, I set it on standby and with airplane mode turned on last night. It showed 97% charge. Now I just check it is down to 94%, a 3% drop. I am wondering whether this is just my unit or normal.
I think I'll do some testing to see how many page turns it take for it to drop 1%. |

I think there is some problem with charging up to 100%. It stayed at 98% for a long time unless you check several times. Hence, it won't show full charge by itself. Once, the battery read 100%, the light does turn from orange to green.
Although, 1% drop for quick consecutive 150 page turns; this isn't true for normal reading. The drop is higher even the page is not being turn. Last edited by OrcaBlue; 03-06-2010 at 07:41 PM. |

Sounds normal. Standby is not "off", so it's still drawing some power.

Arrived!
My 800SG has arrived and is charging now. No problems. Pen was loose in the box, so I can understand how one could get omitted or bounced out during packaging. I immediately wrapped it in industrial grade Velcro for attachment to the top of my device. Adds a nice fuzzy, thicker grip that I prefer.
I transferred my current read via Calibre, which had no problem recognizing the device. Getting to page 102 was a pain ... then I realized there was a table of contents. Doh! But still, it needs that Go To Page function in April's update. I've read a chapter so far as it's charging over the USB. Me like. A lot. Seems to be everything I expected. |

Ah the pain! My new DR800SG has arrived but I am on a trip. No chance to see it for another 10 days or so. At least I had them check that the pen is in the package and charge it for me. Really didn't expect it to arrive so quickly.
