Round 5 - Battery Life

The Nook Color and Galaxy Tab both use a 3.7V, 4000mAh battery (that’s 14.8 Wh, for those keeping track). We could only run one of our two standard battery life tests, due to the lack of HD video playback on the Galaxy Tab. Our WiFi battery life test involves loading a number of pages until the battery dies:

WiFi Web Browsing Battery Life

We saw 8.75 hours out of the Galaxy Tab, and just under 6.5 hours out of the Nook Color. The WiFi edition Galaxy Tab pulled about an hour less than the 9.75 hours we saw out of the WiFi battery test on the last Galaxy Tab we tested, but given the number of tests we’ve run on the two devices, it looks like that’s just unit-to-unit variation; you should get anywhere between 8.5-10 hours of constant internet use out of the Galaxy Tab. 

The Nook Color fared rather poorly, especially given that on a hardware level it looks like it should be at least similar if not better than the Galaxy when it comes to power consumption. I think most of the difference comes down to variations in the rest of the component selection surrounding the SoC, with the display potentially being a culprit in reducing battery life. Barnes & Noble quotes 8 hours of battery life with the WiFi off for the Nook Color, so it matches up pretty well with our result.

    I do not understand how you can have an article, particularly one targeted at budget tablets, and not include Archos. Seriously! WTF! Archos, you guys need to check them out cause apparently you've never even heard of them. They really are the ONLY viable choice for tablets from 3-10inches.

    Still waiting on a review unit, but based on my experience, I wasn't impressed by what I saw from them. I did like the 101, especially for the price, but the 70 wasn't very good. I'm not sold, I need to see more features and better screens from them before they can seriously contend in the Android tablet game.

    GPS. Any list of tablet specs should indicate whether it has GPS.

    For 350.00 you can get the Ipad (1) refurbished. Thats with new battery, shell. Just bought 1 for the living room coffee table. Holds up well to the 500 dollar Ipad 2 in most respects.

    What about the Dell Streak 7? I know the screen is 800x480, but it has Tegra 2. And it's under 300$ on amazon and newegg(no taxes), so its really only about 30 bucks more than the nook. I really wish the local BB had one so I could check it out, as I just picked up a nook the other day and am contemplating taking it back. Any thoughts?

    Its fast, but man I really hated the screen when I played with it. I didn't realize that it was so cheap for WiFi only; T-Mobile is still selling the 3G one at $449...Honestly, I'd give up a lot of that power for a WSVGA resolution - I liked the Galaxy Tab (3G) a lot more than the Streak 7 when I had them side-by-side at the Nvidia CES booth.

    I've been using a NC for about 2 months now and have some comments about it.

    First of all, right now, it is a neat tablet to get because it's cheap and so you get a taste of tablets for a low price. However, this market is changing every day and I expect the NC to lose this value in not too long.

    -the headphone jack has low audio quality. Noise and distortion.
    -raw buggy software and it may always be that way. It's even slightly unstable because they are trying to make custom kernels and it's difficult with the kernel and driver source available.
    -Android 2.x is not great. The internal browser is terrible with its memory management issues that cause hitching and its complete lack of GPU acceleration. Opera Mobile is fast but somewhat annoying in its features and UI design.
    -DSP is not HD capable and there are no HD codecs available for it so I expect it will never do HD video. Even when overclocked the CPU isn't fast enough to play 720p H.264/VC-1 on its own. It's battery slaughter without the DSP anyway.
    -the internal flash memory is very slow, about like a class 2 SD card. Boots slow, app install slow, web browser caching impacted slightly as well.

    Personally I'm looking forward to some new 7" tablets with Honeycomb or another OS, and Cortex A9 or better. But the Nook Color is as I said an interesting first look if you haven't played with a tablet.

    If you're using the 2.3.62 kernel with CM7, make sure you have the latest bootloader (comes with the latest nightly) and give either moboplayer or vitalplayer neon a try for playing your videos :)
