Battery Life

The Nexus 7 has an integrated 16Wh battery, which despite its size delivers extremely good battery life. Our WiFi browsing test saw the Nexus 7 deliver 9 hours of battery life on a single charge, that's roughly half an hour less than the new iPad.

Web Browsing Battery Life

The Kindle Fire comparison is even more impressive - the Nexus 7 outlasts the Fire in this test by nearly 70%.

Video Playback - H.264 720p High Profile (4Mbps)

Battery life while playing back locally stored video is just as impressive. Here the Nexus 7 clocked in at over 10.5 hours on a single charge, 82% longer than the Kindle Fire. Of course with only 8GB of local storage you're going to be forced to stream a lot of content to the Nexus 7, where it will get worse battery life.

Our 3D gaming battery life test shows how bad things can get on the Nexus 7 if you really stress the SoC and display: 4.08 hours. This is actually the only test where the Kindle Fire does better on battery. Do keep in mind that the Nexus 7 is technically doing more work (higher resolution and frame rate), which contributes to the delta in battery life here. 

3D Gaming Battery Life - Riptide GP

With 4 hours on the low end and 10.5 hours on the high end there's a pretty wide dynamic range for battery life on the Nexus 7. Keep that in mind because depending on your usage model you may end up closer to the lower end of that spectrum than you'd otherwise think. The big problem is without tons of local storage, you're going to end up relying on WiFi for content streaming needs a lot more than you would otherwise - which does have a tangible impact on battery life.

The Nexus 7 does take a good amount of time to charge its relatively small battery using the supplied 10W (5V, 2A) charger:

Charge Time

You can expect a full charge to take 3.35 hours, and about 3 hours to hit 90%.

    Maybe Google saw the gobs of cash Apple make from crazy high markups on storage once you lock your userbase out of choice in the matter.

    I'm glad Android has internal competition in the smartphone area for this reason. Time will tell if my decision to opt for 8gb is a bad one, but really since it has no camera I'll only ever run out of space when copying something onto it which puts me firmly in control and I'm fine with that.

    Applaud mentioning that Google is charging $50 for $4 of NAND. Wondering why Apple is not reviewed with such analytic words.

    Brian's and Anand's writing are the only knowledgeable content on this site, with the rest being filler material. That said, still not lowering my ad-block on Anandtech, since Anand drools praise on Apple products, throwing money at a 117b dollar rich company which is:
    monopolistic (in behavior if not absolute terms),
    dictatorial (imposing business-driven restrictions on technology), and
    unimaginative (riding wave of state of the art tech manufacturing, always at the cusp of killing established business models with many players for its sole profit)

    IMO Anand is single minded and is narrow in his views. Yes, he appreciates "the best" tech, but is eager to distance himself from less obvious virtues and legacy concerns. It's also apparent he feels no responsibility and vision towards diversity, choice, and the underdogs in the industry, preferring the elite wherever possible, Intel over AMD, Apple over the rest. By being "objective" and focused on what he deems palatable and suitable, he is no different from Monsanto: technology in a vacuum, umbilical cord as leash.

    And once he is happily on Apple's leash, you can see how his values get whipped around.

    I have not had to pay for cloud storage. The N7 is a play store front-end for media streaming. Google is heavily pushing streaming services over local storage.

    The USB port on this thing is compliant to MHL specs and future software should be able to enable HDMI adapters, but the software is not allowing full functionality yet. The USB port is also hardware compliant with USB OTG, it is just not enabled in software.

    What is there for a reviewer to talk about besides simply stating it doesn't have one? Which they all do. It doesn't have one, this you know already, you're either ok with it, or it's not for you. They know what they did and they still chose to do it. Get over it? Reply

    To be honest, it's a bit unfair to knock on any Android Device for the lack of MicroSD card storage.

    Dan Morrill of Google's Android Team explains why:
    http://www.androidpolice.com/2011/11/18/impromptu-...

    It has to do with how USB Mass Storage works and how Apps and Media mingle in the same storage when dealing with internal storage only.

    Ideally, ALL Android devices should have SD Cards but Android hasn't matured in that department enough to have them on the Nexus Line.

    As I read that, he says they don't have a microSD slot because it would make settings up things harder ("where does the camera save pictures, where should that app be installed?"). I am glad that I only have android devices with microSD slots. I don't agree with the dumbing down of options he wants. If I wanted that, I'd go with iOS. :-) Looks like I won't get any Nexus device any time soon. Reply

    Samsung seem to do it right, the as the main 16gb mem (for example) is split norm 2gb and 12gb (that shows as an SD card)

    and ones with an SD card slot are shown as an second SD card slot

    Yes, a shame that the phone slows down so much when you start filling up the internal memory though, its like it doesn't ring-fence enough for the OS. Reply

    Yeah, I don't think they've omitted the expandable storage slots for any one particular reason but more a combination of them... Usability + cost cutting + working out some technical aspects. Still, it's a compromise and he admits as much.

    I think the best compromise is what HTC did with the EVO LTE and what I believe Samsung did with the SGS3: internal storage is all MTP so apps, media, and the OS can share the space without strict partitions and you don't need to unmount from theOS to sync content, and the external storage is still good old UMS so you can work around MTP sync issues and/or have expandable storage for media.

    It's still a compromise tho, what Morrill states is true, not all apps are built to scan external storage or handle the disconnect of it elegantly. The OS handles it just fine in the case of music/photos IMO (since there's a media scanner) but other stuff can be hit or miss.

    Anyone who buys a device like this with no storage option is just a fool. Let it burn. Reply
