I have an original Kindle and have not been tempted by any of the upgrades until now. The Fire is intriguing but the limit of 8 hours of battery life compared to the months or so on the original (I keep the whispernet off virtually all the time) strikes me as a serious defect. Will the Fire battery last longer if the connection is off? Will it last longer if the color in the display is left Off? I assume there is a simple way to move content from my old kindle.

William, like any other tablet device, the Fire's battery life is about average (and normal) for such a device. As for the battery life when the device is not in use, it will eventually run out of juice on you even if you leave the device off.

Edit to add that adding your current Kindle content to your Fire, presumably Kindle ebooks, etc...will be a fairly simple matter.

It is a backlit device, it will suck up the battery.

The Kindle Fire has an LCD screen (like a normal computer or laptop screen), not an e-ink one, and those need much more power than e-ink screens. Hence the shorter battery life. Tablets with LCD screens normally don't have much longer battery life, not with current batteries - maybe if they used a bigger battery, but then they would get really heavy, so that's not really an option. So I'm afraid there cannot be a Kindle Fire with battery life like regular Kindles any time soon.

So if you primarily use the Kindle for reading and don't need a color screen, you're probably better off sticking to traditional Kindles. E-Ink screens are much easier on the eyes too when reading for a long time for most people.

It should be noted that the 8 hours is how long it lasts when the display is always on.
If it is off i guess it should last several days.

But those are just estimations, i don't think anyone has throughly reviewed and tested one yet.

I personally see the Kindle Fire as a gimmick to get the kids on board. The Kindle (excluding the Fire) were designed for a specific purpose (okay you can use the 3g to browse the net but after 5 minutes it drives you nuts), reading books, so the e-ink technology to facilitate that is perfect, it give an almost identical experience to reading a real book. I love my Kindle because it just does what it was designed for. If I'd have wanted a tablet PC I'd have bought a tablet PC but the short comings on the battery life seriously limit them as useful for reading e-books for more than an hour our two. I travel a lot and a lot of the time I'm sat around at airports, with the Kindle I know I can just lift it out of my bag and it will easily see me through the two hours (even if I've forgotten to charge it) I'm going to spend waiting for a flight. I may buy a Kindle Fire but not for the purpose of reading e-books but for doing everything else.

Um, Syd812345, I pretty sure that whole posting about the Fire using A and AAA batteries was a joke. :)

Thanks , Bryan. :)
Can you tell me ( a very NON technical person who is a retired hospital administrator and 66 years old ) what type batteries will the kindle fire use?

Syd812345, the Kindle Fire has a built in rechargeable battery. It's not something you can change out.

In reply to an earlier post on Oct 4, 2011 2:19:07 PM PDT
It has its own internal rechargeable battery, just like the current Kindles or a laptop. You plug it into the wall outlet until the indicator (I assume there will be a battery indicator) says it's charged, then plug it back in when it's run down.

A big "Thank You" is sent your way !! After having read so many posts
( Kindle Fire) from so many people who are at " different levels of understanding of technical "things", I was getting frustrated as to whether or NOT the Kindle Fire would have batteries. I appreciate your response to a very NON-technical person.

Thank you. Please read my response to SeaLevel274, and receive it as a message to you also.

Syd812345, it's as SeaLevel274 has indicated, the battery will be built-in, and will most likely be similar to a flat, rectangular shaped cell phone battery (as a reference for you). I haven't seen it referenced any where (though I may have overlooked it), but the Fire's battery will most likely not be replaceable by the user, meaning you, if it ever wears out. You would have to send the device into Amazon to replace the battery in this case. However, most devices like the Fire, have batteries that last quite some time, meaning they can be (re)charged over and over many times before finally wearing out. If the battery does ever wear out in what seems like an undue amount of time (i.e. within 6-months, etc...), that would be an issue that you could take up with Amazon if need be. Amazon Customer Service is excellent at taking care of its customers.

Edit to add that I didn't mean to add superfluous information to my response, I just wanted to clarify and add some other info on the battery issue. ;)

I greatly appreciated your taking the time to explain in detail, just as SeaLevel and Jenny have done. I am way out of my league in this forum. I am not a dummy in too many "fields" (retired hospital administrator, now 66 years old). However in the electronic field " Dummy IS me" ! LOL Thanks for putting up with a " not-at-all technical person". All of you who have responded have been extremely nice, and I thank you for your posts.

Well, I didn't want to start yet another Kindle Fire thread, so I'll ask here...

Can the Kindle Fire be in use while it is plugged in for recharging?

If so, that means rearranging my bedroom furniture...but would be worth it. :)

In reply to an earlier post on Oct 4, 2011 3:46:10 PM PDT
Coleen, that's a good question. Does anyone out there who has a different Android tablet know the answer to this? If the Fire is like any other Android tablet, it should function the same when charging (either it will be usable or it won't) as other similar Android tablets (I assume anyway).

Kindle Fire charges through a MicroUSB port, much the same as a majority of Android smart phones and the original/non-touchscreen Kindles. Anyway, nobody here will know the answer to your question to 100% certainty prior to release, but I would be ABSOLUTELY SHOCKED if you can't use it while charging. Now, certainly functionality such as communicating with a computer could be blocked because that also uses the same MicroUSB port, but if you just want to surf the web, play games, watch video or read while charging, it should not be a problem.

The Kindle appears to be one of the first tablets compliant with support for the USB Battery Charging 1.1 specification. This is great, because that means it can charge at full rate through any BC 1.1 compliant USB hub like Plugable USB 2.0 4 Port Hub with BC 1.1 Fast Charging And 2.5A Power Adapter.

And unlike normal USB 2.0 hubs and devices, BC 1.1 compliant devices can charge at full rate even without an attached computer (or if the attached computer is off).

So Kindle Fire users will have more and better charging options than Apple iPad/others (which don't support BC 1.1 yet).

Note with the Kindle fire, you'll also need to get a standard USB micro-B cable like AmazonBasics USB Cable - 2.0 A Male to Micro B (6 Feet / 1.8 Meters), since the cable that comes with the Kindle Fire isn't detachable from the wall adapter.

I charged mine overnight and have been reading about 6 hours with wifi off and still have battery at 76%. Not bad.

Mary McManus says:
Jeff, how do you get the battery percentage? All I'm seeing is the battery icon.

For the one who wanted to know if you can read while it's charging, absolutely you can. Probably the best way is to turn it upside down and that way the cord will plug into the top. Then you can lock the screen by clicking on the gear icon for settings and selecting to lock the orientation.

Click on the settings icon in upper right, then +more and Device it tells you the actual percentage available.

I have had the Fire since the 16th, and have listened to several audiobooks so far. I have had to recharge the Kindle twice after the initial charge when I received it. Not terribly thrilled with the battery life. I do like the fact I can turn it plug side up, and be able to read the screen.

Can we use our old white usb power adaptor that came with the first Kindle on our Kindle Fire? It has an AC plug and a usb plug.
