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.

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

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.

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%.

    Not everyone is like you.

    All my music lives in Spotify and I stream the vast majority of the movies/tv shows I watch. Plus, 90% of my tablet time is spent reading or browsing anyways.

    Expandable storage is nice, but it certainly is not a blocking issue for my usage.

    I love that how all the screaming for future proof options is out the window.
    Steve Jobs loves it too.

    Agree. I think the Retina Macbook is the poster boy for this though. Not having upgradeable ram on a £2500 laptop is pretty inexcusable. What if I need more than 16GB to run virtual machines etc? It's the only thing which keeps me from buying one. Reply

    well, I have a pretty good set up at home for streaming most media to tablets and media devices. The extra 50 bucks for 16 gig was not worth it to me since I will not be traveling with it. I can watch all my movies, listen to all the songs in my library and read books. There are some decent apps - stock ticker, netflix, skype to mention a few. For 200 bucks it is a good deal if you can do without the extra storage or a sd card which I can... Reply

    Root it, install Stickmount, use any removable media with a USB OTG cable. If there was a better 7" alternative for $50 more or even $100 more that comment might make more sense... But as it is, the Nexus 7 is still a fantastic device and unless you're very tech averse the lack of expandable storage out of the box really isn't a big deal...

    I'd even take a gamble that most people who'd balk at rooting the thing will probably never store enough media or games on it to really have an issue with 16GB, the 8GB model will be tight if you start to download big games left and right tho.

    Boy you have no clue on the public and general end users.
    Let me help.
    They are utterly clueless, and when faced with storage constraints, they have no idea what to do, and deleting for space is above their user skills.
    That's the vast majority of purchasers.

    Don't confuse apple users with Android users :)

    We don't call them SHEEPLE for nothing ;)

    A large portion of Android users are above the norm and believe in using their devices for more than Steve Jobs every believed you should get away with.

    Perhaps you should burn every iOS device for not having expandable storage. Reply

    That article talks about the lack of SD cards, and honestly it makes sense to me. Also, keep in mind that they do have a 16 GB Nexus 7 available for purchase. Although, I think it's currently sold out.

    Of course it's sold out. Reply
