Battery Life: 6 Hours

I swear the Kindle Fire has a hard stop at six hours of continuous use. Regardless of the nature of my benchmarks, the Fire always dropped out after six hours of use. I ran our video playback test, our tablet browsing test and our smartphone browsing test - in every case the Kindle died in around 6 hours:

General Usage - Web Browsing, Email & Music Playback

Video Playback - H.264 720p Base Profile (No B-Frames)

Obviously these only matter if you're going to be using the Fire as a tablet. As a Kindle, you can expect longer battery life as there's simply less work going on and the majority of the SoC is just power gated during that time.

Either way you're still limited by the fact that the small chassis of the Fire can only accommodate a 16Whr battery. That's around three times the capacity of a high end smartphone battery, but it has to cope with a much larger (and more power hungry) display.

    The original Nook Color, at $200, was an heck of a deal. The current proprietary tablets (Nook Color 2 and Kindle Fire) are a lot less compelling due to the arrival of non-proprietary tablets at the same price point. Those are.. non-proprietary, and offer arguably better features.

    I'm still happy ith my original Nook Color. WHen it gets replaced, if it does, it probably will be by a true, un-walled-gardened, tablet.

    Ars had a good review of the Nook tablet here:
    http://arstechnica.com/gadgets/reviews/2011/11/lea...

    "I have less doubt about the Nook Tablet as a capable product than I did about the Kindle Fire. The experience is not frustrating or jagged and doesn't feel as unfinished... However, I do have some doubts about the value of the Nook ecosystem. Amazon's selection in all categories seems a bit more diverse..."

    I wanted an entry level tablet that was an eReader. Check. But ...

    1) I really miss having Skype on here. Really.

    2) The lack of Google native apps results in my using the browser for gmail, Reader, et al. And then Google gives me links to all the other apps. Not the most comprehensible experience.

    3) The single/double/drag tap issues are more annoying than they need to be.

    4) wiFi isn't immediately available when the device wakes up. It takes some number of seconds to make the connection. The "wiFi not available" error is easily resolved by me tapping again. Why isn't is resolved by the app / OS waiting instead?

    5) The entire software experience seems less than fully baked. Yeah, I get the Christmas rush thing, but I don't have experience with Amazon updating software. Hope isn't change.

    6) The device feels familiar because I'm used to my Droid Inc. The speed is better, and the screen size is acreage versus postage stamp.

    If there's ever a phone that just 1) phone calls 2) text messaging 3) wiFi hot spot 4) non-larcenous plan, I'd predict that, and a tablet in this form factor, will kill the smart phone business.

    Great review.

    1. I dont miss it at all.
    2. Not true. It comes preloaded with an email app that has gmail setup.
    3. Dont know what your talking about never have this issue
    4. Dont have this issue and I use mine all day long.
    5. Have no problem with the software at all. Everything works very smoothly.
    Just want to add...I've had an Ipad since launch and I have since stopped carrying it around. This fits in my coat pocket for use at the gym while doing cardio. At work, on my desk for quick web browsing. RSS feed for all Tech related news. Gmail. Reading on the subway. Uses my phones hotspot in the cab for use. Quick download of movies. I think its a great device.

    In your conclusion, you state that $199 should be the entry level price point now. I'm anxiously awaiting your review of the Nook Tablet to see if that extra $50 is worth it (excluding my personal bias towards B&N for their willingness to fight back against Microsoft's ridiculous patent war against Android).

    Agreed, the new Nook looks interesting. I remember reading it has a larger battery than the Fire. Locking all but 1GB of its memory to B&N content sucks, but I'm sure someone will take that limitation off.
  • Lucian Armasu - Tuesday, November 29, 2011 - link

    Hardware wise, the extra 8GB of internal storage, extra 512 MB of RAM, and microSD slot, I think it;s worth it. Still I think the extra $50 would be worth it a lot more with the full Android experience. If the other Android manufacturers could put android 4.0 on an equivalent tablet to Kindle Fire, and price it at $250, I'd pick that one any day. You can still get all Amazon's services on the full Android, too, so no point limiting yourself for $50.

    I don't understand why you are comparing the Fire with all the tablet out there that's in a different class. What it should really be compare to is the Nook Color, and the Nook Tablet. Which either of them were included.
  • Wierdo - Tuesday, November 29, 2011 - link

    Yeah I read a review on Ars about it and they think the Nook tablet is a more capable product but Amazon has the edge in the ecosystem department, link posted on this thread somewhere if interested.

    We'll have a Nook Tablet review that touches on the comparisons to the Kindle Fire relatively soon :)
