Battery Life & Performance

The Eee Pad has an integrated 24.4Wh battery as well as an optional external 24.4Wh battery courtesy of the Transformer dock. The tablet by itself has battery life similar to that of the Motorola Xoom, and shorter than the iPad 2. With the dock however we measured a 64% increase in battery life in our general use test. With over 15.5 hours of battery life on a single charge, a docked Eee Pad is pretty impressive.

General Usage—Web Browsing, Email & Music Playback

ASUS tells us we aren't seeing a near doubling of battery life with the dock in use because of inefficiencies in the current firmware—something that could improve with the May firmware update.

Video playback battery life is identical to the Xoom. Remember NVIDIA's Tegra 2 doesn't completely accelerate the H.264 decode pipeline, so there's some software offloading that unfortunately keeps the Cortex A9s awake during our video decode test. As a result the Eee Pad and Xoom post lower-than-iPad results here.

Video Playback—H.264 720p Base Profile (No B-Frames)

With a 1GHz Tegra 2 under the hood, the Eee Pad performs just like a Xoom:

    Device synergy is exactly why windows is a must for me. I write all sorts of apps, macros, and scripts that help me get **** done fast and efficient. I can draw a note on my screen, take a screenshot of that note, upload it, get a shortened url for it, and send that url to the computer in my bedroom (and make it automatically open up in its browser) all in a few keystrokes. There aint no way you are ever going to be able to do half of that with an iCRAP or an android. And even if you could, why reinvent the wheel? I did not spend hours writing custom visual C programs and autohotkey scripts just to turn around and be asked to set up all new stuff for some little piece of junk fad. If it cant run my stuff it is useless to me. Reply

    Let's say you have a desktop, a notebook, and a tablet. All have windows and all have a dropbox mapped to drive S: So I create files called "linkshareMain.txt","linkshareTablet.txt", etc. And on each device I have running in the background a program that reads those files parses out urls and opens each url in a new browser tab. So if I want to send this article to my notebook I just click on my desktop shortcut called "linkshare Notebook.txt" and paste and then save&close. Soon as my notebook is awake it gets that link and opens it and deletes that link from the file.

    I can also do the same thing using email. I just have a program that parses through all incoming email searching for keywords like: launch_urls_nb625: and then it treats all following lines of text as urls and opens them. Can also launch other programs, load pdf files, play videos, etc. So if I am at work and I want to read this article when I get home I just send myself an email saying launch_urls_main625: and this article comes up as soon as I wake my computer.

    It is fairly easy to set this kind of stuff up, and I will not migrate to a new OS or architecture unless they give me, the end user, this kind of control.

    Hey, could you please specify what program reads and parses the text file in the background? I find this method of yours very interesting and would like to give it a try. Reply

    Wow, if I want to transfer links between computers I would just bookmark it and Xmarks does the rest. That's like one click.

    But it's good that you know how to do all that stuff the hard way; we'll need people like you if the internet breaks.

    Yeah well when you deal with a lot of news articles and all sorts of random stuff, bookmarks quickly become impracticle. I have seen many a bookmarks/favorites page that will scroll down for miles and miles. I find that sort of thing unacceptable. I never bookmark a page I will most likely only visit once. Reply

    Sorry to be pedantic about this, but everyone is really worried.

    Can you confirm that the GPS hardware works without wifi connected?

    Does the GPS turn on and get a signal even if your wifi is off?

    I understand that some apps (e.g. Google Maps) require a Wifi Connection to receive *data*, but does the Transformer require wifi to be connected to receive *GPS* signal?

    Could you download a GPS app which doesn't need data (GPS Status works) and confirm it works?

    Thanks for the in-depth review and for putting up with the GPS nonsense :)

    That is, use GPS status with the Wifi Off, I meant. :) Reply

    I'd like to see IR transmitters integrated into tablets and cellphones. They may be archaic, but it would be nice to be able to use an android device as a universal remote. Reply

    Are the performance issues in honeycomb something that needs to be fixed with quad core processors? I feel like that's throwing raw horsepower at a problem that should be fixed with better programming. Reply
