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:

    Oh I love the APU, and I hope it gets picked up by more hardware manufacturers.

    But this is all recent stuff. But thats not to say its too late for them to get in on the action, just that they are going to be fighting an uphill battle. And this goes for Intel just as much as it does for AMD.

    I know Intel is working on porting Honeycomb to x86, and they could give them a huge boost. But I still think that the current x86 CPU's are simply too power hungry for a proper tablet. They may be upteen times faster, but that doesnt matter as much if you end up with less than half the battery life in a machine that is thicker and heavier.

    This tablet really seems like a winner and no surprise it comes from Asus who essentially introduced the netbook market. As stated in the review, $200 less than the Motorola Xoom (although it doesn't have GPS) is outstanding (shouldn't the chart on first page state $599 for the Xoom if we are doing an orange to orange comparison *sorry Apple*)! I like the versatility with the keyboard, mouse and battery dock. In my opinion, all it needs now to be the ultimate productivity tool is a stylus, like the HTC Flyer's (active digitizer technology by N-trig). Price it at $450 then after the upgrade. Here is a link that shows and tells exactly why and when paired with a product like MS OneNote, it would be unbeatable:

    Tablets still seem like a toy to me. I'm probably gonna wait for win8 to come out. Reply

    Although I really like the iPad (and have almost bought one several times) I do agree that its a toy for now (albeit a very cool toy).

    The "work" that I could do with an iPad, like emails, I can also do with my iPhone. I really need something like Windows 8 as well. If they can ever make something for an iPad that can run windows XP through a virtual machine, then that would change things quite a bit.

    Well, this might change things...

    Woops - this isn't a real virtual machine - more like a remote control app for a virtual machine hosted on a server. Still pretty cool, as I use a lot of virtual machines, all windows XP based. Reply

    Love the idea of the dock, should definitely be worth the price, once they can double the tablet battery life with a firmware fix. Really will give the best of both worlds.

    One thing I'd love to see Asus do is think about bumping up/offering a larger size screen. I realize that this will shorten battery life, but coupled with the above mentioned firmware fix, it should give a longer life (with the dock) than it would otherwise. Simply put, I've got a 10" netbook, and normally have to use it with the screen about 18" from my old eyes, in order to easily see the print (either that, or switch to a lower resolution, which isn't really a good choice, IMHO).

    Also, here's a clue, to Nvidea. Not everyone has a smart phone yet, so don't plan on only making smart phone docking to tablets/netbooks your only choice, or you're simply screwing your own business/profit.

    "I've been thinking about device synergy, something I brought up in our PlayBook review. The problem is as follows: if I'm on my desktop with half a dozen tabs open and perhaps a PDF as well, but I decide to switch over to a tablet - there's no quick way that I can transition my reading environment between the devices. What I have to do is sit down on the couch, whip out my tablet, and manually navigate to each website and redownload/open the PDF"

    That was my suggestion/comment in the first Xoom giveaway. :p

    If you have an android phone or tablet you could use a program in the Google Chrome browser called chrome to phone. It basically sends the website to your device and your browser opens magically. Reply

    Great review, thank you.

    There appears to be a lot of confusion about whether or not the US version of this magificent tablet will a wifi only version with GPS.

    This review states that there is no GPS in the US wifi only version. Other sites and spec references all say there is GPS though. Asus currently only has an international spec site that is pre-today's US release date announcement.

    SO, this is the first I've heard of there not being GPS in wifi only TF101. It has been confirmed that the UK and earlier released wifi only models do in fact have GPS, but I understand the US version could be different.

    Can someone please confirm with references? Thank you very much!
