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:

    Why no gaming benchmarks? I think they're important to show what a poor performer the Tegra 2 GPU actually is. Reply

    Owners are saying a new firmware update is rolling in at the moment, fixing the video camera stutters. Reply

    Does downloading a third party app fix the issues with the camera? Reply

    You can buy it at Target. When you add the Transformer to your cart and use the promo code TCA27BAR, you can knock $40 off the price. Check <a href=" Reply

    This is a IPAD2 killer and this has now already dropped in price! It is currently sub £400 on Amazon! - Reply

    I do not generally write reviews but this tablet is worth it. I have owned(and returned) and Motorola Xoom and have tested the Ipad 2. BOTH are nice devices for sure but a tad bit overpriced and I am not a huge fan of the boring iOS customization options. For $399 (Asus Transformer 16gb version) you get the 10 inch tablet, you get the Tegra POWER, the nice sound and the latest Android tablet operating system (honeycomb) which is the perfect combination.

    Device feels very solid in hand, not too light, not too heavy, all of the apps from my previous Mytouch 4g work on the tablet and it functions very well. Battery life is GREAT, I set it to leave wifi on permanently without disconnecting and took it off the charger at 9pm yesterday, used it to tweet, browse and type a paper while listening to non stop music until about 1-2am. Woke up today at 9am, my new emails were synced and gtalk was running.....STILL had 69% left. It is now going on 1pm, i haven't used it much besides for my alarm clock and listened to another 10 songs and tweeted while i got ready for class and its sitting at 63% now.

    - Great Battery Life (Without the Keyboard dock's extra power source)
    - Nice weight, does not feel cheap
    - Android 3.0 for tablets is a great step forward to set it apart from everyone else just using the phone OS
    - SPEED
    - Can handle ALL tasks( Recreation, Games, Music, Work documents, homework, etc) My laptop has been put to rest since owning a table.... R.I.P.
    - PLENTY of apps for everyone and everything you are interested in.
    - Google talk video chat works like a charm
    - Cameras take good quality pictures

    - Not a fan of the placement of the speakers since they put them towards the bottom. My hands sometimes blocks them while holding the device but i can still hear the music just fine(even though not as loud)

    - The charger is kinda short, that is acceptable but it seems like when you plug the Tablet to the computer it stops charging when you have the screen on, i found that a little strange. Safety reasons? im not sure.

    Final Verdict: If you want a GREAT tablet that is affordable, has video chat, music, games, apps, full internet browsing abilities and PLENTY of customization options then this is your device! Easily replaced my new laptop, much lighter, better battery life and can do the same things...literally.

    *** P.S. If you will buy this Tablet I suggest you have compare price before you decide at -->

    I've never felt the need to comment even as a reader since basically inception..because the reviews are always great.. as is the tech info. This is no exception, but I wanted to put my $.02

    The tf is a device that could have solved some problems..however, it is clearly beta from head to toe. It's an incredibly frustrating device to use. Unresponsive is being kind. 3.1 didn't solve the issue, the trackpad being unable to disable touch click makes it useless. One cannot even type a reply like this in the browser with the hard keyboard due to tremendous lag (including alternate browsers, though opera is better)

    it's a real shame this wasn't a more considered device prior to release.. and imo, since asus as speculated the sequel in q4, don't pay to beta test honeycomb and their product. This is simply not a product ready for prime time. Some of the blame lies on asus, some on google, but either way, by the time things are resolved, there will be much faster hardware.. wait six months.

    Can the USB cable on this unit be plugged into a USB connector that plugs into a car's cigarette plug for charging and if so what would be the time involved? Reply
