Kindle 3 battery life

ylsul · 09-03-2010, 11:23 AM

Hi,
I got my K3 on release day. Did a full charge when I got it (charged until the LED turned green). I installed 3 books, and then had two good reading sessions of maybe a few hours.

I pulled out my Kindle last night to show some friends, and discovered that the battery had drained. Is this normal?

Should I be turning off all the wireless functions? Even with them on, I had hoped that the battery would last longer than a week.

I'm charging it up again to see if it does the same thing this week.

It is up 10 days so if you're downloading a lot or its busy indexing a large number of books then it will drain the battery faster. From what you said, I'd expect slightly more though.

You didn't mention whether you have the Wi-Fi or the 3G model. If you have the 3G model, leave wireless on, and are not connected to a wireless network, your battery life will be significantly reduced. This is because the 3G takes more power than Wi-Fi and 3G gets turned off when you are connected to a wireless network. The best battery life can be achieved by turning wireless off when not using it.

Amazon states the following battery life:

Kindle Wi-Fi and Kindle 3G, wireless off: 1 month
Kindle Wi-Fi, wireless on: 3 weeks
Kindle 3G, wireless on: 10 days

At any rate the battery life that you have experienced seems pretty short. If it doesn't improve after three charge sessions I would contact Kindle CS.

Yeah, I should have read the manual! I've got the 3g/wifi version.

I turn my wireless off when not in use and am leaving it in sleep mode.

I'll do this for a month and then try shut down mode for the next month.

That way I'll be able to tell if it makes a difference in the duration of the charge.

I'm not sure the battery indicator is accurate, either. I left mine on the charger overnight, while indexing. In the morning, a quick search revealed no unindexed files. I read for 30 minutes and then emailed 3 small files from my computer to *@free.kindle.com. My battery indicator showed half capacity after they downloaded via WiFi. I stuck it back on the charger and 15 minutes later, the LED was green. I've decided to let it drain completely before the next recharge and then see what happens.

I bought a kindle 3 wifi two weeks ago. Initially battery life looked okay (loaded 11 books and a newspaper). Kept wifi on and I read approx 2 hours/day. First recharge was after 7 days.
I then took a trip through Heathrow. Whilst in the BA lounge waiting for my flight I tried to connect through the free wifi. This locked up my Kindle (went to clear screen). After attempting a reboot (slide the on-off switch and hold in the on position for 20 seconds) the Kindle restarted but the battery lift from then was awful - 3 day from full charge to empty. When back at home this cycle continued for two more charges i.e. 3 days from full charge to empty. I was about to return the Kindle to Amazon but first recharged the device and fully rebooted it again (as above). Since then the battery life has been excellent - after three days the battery symbol is still showing full. I think that my Kindle must have got into a processing loop and hence discharged the battery ultra-quickly. The Kindle now seems fine.
So, if you are experiencing battery life issues, go for a full reboot and battery recharge before sending the Kindle 3 back to Amazon - good luck!

well, prime your battery a few times before making a few comparisons(charge, discharge almost fully, charge, discharge almost fully)

and keep in mind that its up to 1 month wireless/3G off... if you read 2 hours a day with only 50 page flips ,then you probably can last a month... if you read 6 hours a day with 300 page flips, then it won't...

my DX G is 1 week with wireless on, 2-3 off... i read a lot(5 hours a day, read a lot), keep wireless on half the time whilre web browsing, manage to squeeze 1 week out of my DX (have it for 4 weeks now6
