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.

    The specs for Archos 70 say:

    • High resolution screen, WVGA 800 x 480 pixels, 7'' TFT LCD, 16 million colors
    • Capacitive multitouch screen

    Yes on the resolution. No on resistive.

    " Overclocked kernels, custom skins and launchers, updating the ROM to the latest nightly build, anything you could possibly dream of. That's something you just won't get with the Samsung..."

    Samsung Galaxy Tab was rootable even back in 2010.

    I will never understand this new fad of tablets.. to each is own i guess.

    Bought one for my wife, rooted in about 15 minutes she uses it for reading and gaming and surfing. Not everything works perfectly, but the battery life is more than decent and it is very much a usable product. We read from both the Kindle App and the B&N App with no trouble. I got it during the Ebay B&N sale for $199 enough said :-)

    It seems like the WiFi-only Galaxy Tab packs OMAP3* as well, not Hummingbird.
    this was reported here: http://www.thegalaxytabforum.com/index.php?/topic/...

    can anybody confirm?

    Did you read the article before posting this? It does so.
  • Stanil - Wednesday, May 25, 2011 - link

    In the original it said Hummingburd and PowerVR 540, they changed it post factum :) Thx for the specs, I wasn't sure if the castrated version was only for Europe.
  • dukepeter - Wednesday, May 25, 2011 - link

    yes, i read the article, and i remember clearly it said Hummingbird and PowerVR SGX540.
    But yes, they have changed it now. i wish i had been wrong =|

    Yeah sorry, I had changed it on my document file but apparently not the actual article engine before posting - sorry guys, that was a big time proof-reading error by me.

    It felt very bait-and-switch to me, I never noticed it was SGX 530/OMAP3 until I ran the gaming tests and went o_O. I don't mind too much about downgrading the Bluetooth, but the SoC downgrade is pretty terrible.
