Poll: Real-life battery lifetime experience

[L1Wulf]

My last post was done during single digit weather (Fahrenheit, I should point out) and the night after posting, the battery bar returned to full. Today, it dropped to three bars prior to going out into the cold. Since the above post, there have been 300+ actual pages read--figure in setting bookmarks at the end of each "reading session", perhaps an average of five, and unsetting said bookmark when starting, not to mention three to five power down/up per day and the occasional menu browsing, accidental button pushing, etc., we'll say approx. 400 screen updates... that comes to approx 1600 screens for four bars (full battery), which seems to coincide with other observations here.

Perhaps there will be more page turns during the third and second bars, time will tell.

4) can recharge

You left out cheap and easy to replace and upgrade as the tech continues to develop.

But then, I realize you weren't trying to make a comprehensive list. Those are just my two favorite aspects of rechargeable AA/AAA batteries.

I've had my reader (daily edition) for about two and a half months. I've read almost 4 books with it, 800+ pages per book, and all was well until about a week ago. I noticed that the charge time was reduced, and now, greatly reduced between charges. It's like the lithium battery has developed "memory", and is only good for a couple hours. There were a couple times I didn't let it completely discharge before recharging, but shouldn't have caused this. I just ordered a new battery, so we'll see.

Reminds me of the tootsie pop commercials. How many licks to get to the center of a tootsie pop. The world may never know...

But they do know how many licks, average is 252, LOL. Really haha. sorry couldn't resist. check it out yourself ----> http://www.tootsie.com/gal_machine.php

another factor, is one reading book after book, a breather of a day or so between books etc.....the things lose battery life just sitting unused as well.

Depends on whether asleep or shutdown as well... both my 300 and 650 hold full charge for month plus when shutdown and my 505 needs a charge every 10-14 days with several hours reading per day (and I'm a fast reader so that represents at least 2-300 pages per day) but only put to sleep

First thing.
The poll figures are invalid. The Sony ereaders can go for *weeks* between a charge, NOT just hours.

I last charged my 650 on 26/10/2010. 1 month ago today.
I haven't plugged into the computer in the last 3 weeks either; No new books to download.
The battery meter says the battery is still 75% full (3 bars) and it only dropped to that level on Tuesday this week. (23/11/2010)

Daily reading sessions total 3-5 hours.

Powered OFF between sessions not put in standby.

I charge my reader almost every two weeks, sometimes it'll last close to three weeks. I read an absolute minimum of two hours a day, everyday.

my PRS 500 would last FOREVER. 2-4 weeks but would die "suddenly" when it was time

I LOVE my new DX but the battery life is nothing like the sony. 2-5 days of heavy reading (while the sony would go 2+ weeks heavy reading) for me heavy reading is 4-8 hours a day. (yes thats radio off) I wish they would have used the space inside the DX to install a massive battery :-)

An old post, but since it's been recently quoted...

I just spent a month on a ship, no internet access in that time, so the only time I connected my 300 to my laptop was to charge it. I did that once, when the battery indicator was down to 2 bars (of 4). I typically read 2-3 hours per day on the reader (also had access to pbooks) and tend to leave it on standby. I can't remember whether I charged it the day before I boarded, but on the assumption I did, I still got 2-3 weeks before I charged it, and it was not fully discharged when I did.
