how much does 3G or Wi-Fi affect battery life?

ovaldisk · 07-29-2011, 12:23 PM

I assume that turning off 3G and/or Wi-Fi will help
conserve battery life, but just how much savings
can I expect? (in hours or percent)

Since 3G is running off AT&T cellular/data networks,
it should use more power than Wi-Fi connected to my
home router, right?

Thanks in advance!

I have had mine for 2 weeks now. Using Wi-Fi only and keeping it always on, have resulted on a battery life of 1 week. I have used 3G only twice.

Please consider that using 3G will consume a lot of battery specially if you are moving and the Kindle needs to search for a new connection.

Hope this helps;

Turning off wireless will massively extend battery life. A 3G Kindle will need recharging every few days if you leave the wireless on; turn it off and you'll probably get a month between charges.

I keep the wireless turned off on my K3 to maximize the battery life. I only turn it on when I am searching for a book or downloading one.

Does the 3G or Wi-Fi still consumer power when the power in standby(screensaver) mode?

Thanks!

Yes. Even in sleep mode the Kindle is still talking to Amazon's servers occasionally, looking for new items to download, etc.

Same here. I only turn it on to download something to the Kindle and once that's done it goes right back offline again. Of course I play with the apps I've downloaded (mostly games) so I still burn through a charge fairly quickly but I like to think that it still lasts longer than it would with my wi-fi turned on.
