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.

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%.

    My Kindle is fulled with books and audio books and I need more space. I am seriously thinking about purchasing the Nexus 7 as a replacement simply because XDA has provided a way to add more storage space via a dongle. Still, my eyes are shouting for a 10" reader as I know the 7" Kindle is always stressing as it is. Reply

    I would imagine it is the beginnings of an anti piracy drive as that is such a hot topic on Android and a key reason why some app just aren't available for it. Which is a great shame as having a Micro SD slot is emminently useful and cheaper than paying for manufacturer added storage. Reply

    iphone collection packs are readily available on newsgroups and websites. No more piracy on android than ios. That's a fallacy perpetuated by apple lovers. Nothing sneaky about leaving off a micro sd slot. Dead trigger was given away because of one of two things: The game sucks an reviews show it, or they just are apple lovers who ported it to give it away to hurt android. Why would you give your game away due to any piracy? No amount would make a sane person give away their work for good. There are NO honest people on android?...LOL. Sounds like a scam to me. How does angry birds make money then? OK, a 3rd option; they saw sales sucked so went with whichever had better sales and publicity stunt for the other platform (in this case android). I'd venture to guess sales still suck on IOS too... :) No amount of publicity crap will fix reviews in the 40's. Rovio isn't complaining about android sales.

    Does your ipad3 come with micro sd? Must be because of all that piracy huh? Sounds like BS both ways eh? For $200-250 what did you expect to get? They blew away the kindle fire, asking much more is asking for the impossible at this price.

    Make a better game that people enjoy (and isn't just a gpu fest) and it will sell. End users don't crack games, professional groups do and they do it just as well on ANY platform (including the PS3 now). Heck you can buy an xbox360 pre modded and ready to happily play your copies. Yet, for some reason people spew comments about PC's being so easy to pirate on...LOL. PC games have craploads of patches, thus needing more skilled users to update and crack said updates. I'd say it's tougher on a pc, where any monkey can buy a pre-modded console and boot a burned game from release groups.

    As someone already said, most users can't even copy/delete files. Witness the number of people in forums etc asking why their pirated PC game doesn't work. "the game says insert disc etc, where's the crack?"...Umm, gee, did you check the \crack folder? Bother to read the nfo file?...ROFL. Followed by the inevitable "how do you open a .nfo file?" and it goes on an on. Worse, some just can't get past "how do you open a rar file, or .001, or .part1.rar"...At some point someone says RTFM or "google it" :)

    The fact of the matter is that there is little incentive to jailbreak an iDevice anymore because Apple has added most of what was missing previously. You also lose alot like when Apple release a new iOS and you have to wait for it to be jailbroken.

    However, for most Android users who do not own first party Google devices (at least the ones that still get updates...!). you need to root your phone to install updates in a timely manner. On most FAQS about rooting your phone there is inevitably a section discussing pirated apps. The availability and proliferation of pirate apps for Google is certainly nothing new, perhaps you have been willfully ignoring it. The stats on it from most of the developers who mention it are absolutely shocking.

    This is the downside of having more technically adept users I suppose, but to pretend that it either doesn't exist or even more crazily that iOS developers release thei product on Android free to hurt the platform (hmm...) is paranoid delusional.

    The fact is that Angry Birds on Android is free and *ad-supported*. It is not free. Rovio is at least canny enough to realise that the target market aren't prepared to even pay 1.99 for their hard work, and even those playing ad-supported games still complain about the in-game ads and use ad-blocking software so that still doesn't solve the problem. The 360 and also PS3 do ban users that they detect using pirated software online (everyone seems to play multiplayer these days) so no it is not just as easy to pirate on console to how easy it is on the PC.

    I think it should be "winning a higher level accolade" instead of "winning a higher level allocade". It's always baffling to see pro tech editors not using a simple spell-check to finalize their articles. BTW, a nice article (as usual on AnandTech). Reply

    It's fear and low self esteem.

    I'm curious now if a better flash memory controller is part of what gave iPads the fluidity lead up until this tablet, how do they fare in NAND performance? Reply

    You don't actually lose Amazon's video service. You can view Amazon Prime videos in any standard browser, I've got a shortcut on my Nexus 7 which just goes straight to Amazon's Video Service. What you do lose is access to the Lending Library. Reply

    Good point. I use Amazon VoD a lot, which is the best argument for myself in getting a Kindle Fire over this thing.

    I wonder what the difference between the KF and Nexus 7 is in terms of how long it takes to get from the home screen to actual streaming video.
