Battery Life

The Transformer Pad Infinity features an integrated 25Wh battery, similar to the original Prime. You can obviously extend battery life by docking the Infinity into the optional keyboard dock.

Without an increase in battery capacity, you can expect a drop in battery life compared to the Transformer Prime as there's a leakier SoC, faster DRAM, higher resolution panel and brighter backlight to drive. The drop isn't huge, but it's noticeable:

Web Browsing Battery Life

While the original Prime pulled just under 9.5 hours, the Infinity borders on 8 hours of continuous use on a single charge. It's very similar to the battery life from the original Eee Pad Transformer, and better than what you can get out of a TF Pad 300. Eight hours isn't bad by any means, but it's the price you pay for maintaining portability while driving up performance/display.

Video Playback - H.264 720p High Profile (4Mbps)

Video playback battery life is thankfully quite respectable on the Infinity. I haven't had time to run the Prime and TF Pad 300 through our new tablet video playback test but at over 10.25 hours there's really nothing to complain about here. You can watch a few movies on a single charge, which is great for anyone stuck on a long haul flight.

3D Gaming Battery Life - Riptide GP

For our gaming battery life test I'm not sure just how comparable the iOS/Android numbers are because it's quite likely that the NVIDIA hardware is actually doing more work here. But the important takeaway is the significant drop in battery life compared to the TF Prime. What we're likely seeing here is the penalty of the leakier SoC combined with the higher speed memory and increased memory bandwidth demands. If you're gaming on the Infinity, just plan on having a charger handy.

    It will definitely be so much more. Rather than a smartphone OS on a tablet, it will be a bloated desktop OS on a tablet. Awesome!

    The truth is, people on both sides of this argument are making some valid points, but are having a lot of trouble listening and understanding the validity of contrary opinions.

    Only time will tell. There are things about Surface that look exciting, but there are lots of ways it can go horribly wrong.

    I'm actually quite interested in the surface pro. I want something that I can pretty easily carry around, since I don't like carrying heavy things. I also really want good pen input, since I would take notes on it, and as an EE student, a lot wouldn't be words, so pen input needs to be good. Finally, I love the fact that if I have any apps on it that just don't work with metro, I can always drop back to the desktop to use it, just in case. Reply

    Plus the boot loader will be unlocked on the Asus vs. the Microsoft so you can install your own OS upgrades or even full desktop ARM-based Linux. Reply

    Having come from an iPad to the TFP, I think Asus has a better looking, sleaker design than Apple. I know most people don't jump ship from ios to Android, but it's nice to see a product that kind of compete. However, like the ipad2/3 features, there's not quite enough to make me want to sell my TFP and upgrade. Keep it up Asus...

    My job gave me an iPad 3. When I got sick of it locking up on pages and stuttering, and the verizon 4g being enabled destroying my wifi speed when I left it on, and I got sick of pptp vpn connections dropping every 20 minutes, and I got sick of scrolling making it freeze solid for a few seconds, and I got sick of games like blooms td 4 completely locking it up... I'm really wondering how much they pay sites like this one to claim it's a great device. The lack of true multitasking alone. It's so annoying when network applications get frozen in the background and useless iOS tries to unfreeze them.

    I got the TF201. It's superior to the new ipad in every single way. Even facebook is better on it, and that's not supposed to happen. You can play temple run on both and watch the stuttering mess that is the ipad drop frames while the prime has no issues at all. And that's without talking about the stupidity of having no expansion slots, or the stupid 4:3 screen, or being so technically incompetent you have to exactly double your pixel count each time because you can't code scaling graphics into your design. Do you have to buy all new software for your computer when you buy a new monitor? You can't even download anything. All that and it's heavily and uglier also.

    The iPad is a toy with a broken OS on it. The Transformer line are actual desktop replacements. You can't even compare the two. You might as well compare guitar hero to a les paul.

    "'m really wondering how much they pay sites like this one to claim it's a great device."

    Dunno. How much are "they" paying you? It’s probably about the same.

    It's not that big of a deal really. You can spot bad review sites with biased reviewers pretty easily. trustedreviews is the only decent review site anymore. They just didn't have any information on the new king of tablets yet. Reply

    I had a similar experience. My wife got an iPad 2 for her class in school for a semester and she absolutely hated it when compared to my old Motorola Xoom (yes, the original one).

    While iOS transition animations are always smooth, iPads are far from stable. On an Android tablet, while some of the UI transitions need work, you never get into a situation where the device freezes completely because the OS will force-close the app if it does. Apple wants to hide their imperfections from you, so iPad just takes a dump with no warning.

    Another thing that's annoying about the iPad is that for all the hype about the well-designed apps, iOS applications are very inconsistent. You don't know who nice it is to have a consistent location of the back button until you don't have one.

    I'm not saying that iPad sucks, far from it--it's a very nice device. All things considered, I can see that it could still be called the best tablet, though I prefer Android. On the desktop side, I actually prefer OSX for work, because it has a better command-line interface thanks to its BSD roots. I'm a programmer, so command line is more important for me. I'd probably prefer windows if I was doing graphics design for a living.

    This religious fervor about how "magical" the iPad is does make you wonder about Apple fanatics. It's not unique to Apple fans, but Apple fanaticism does seem to have a more cult-like feel.

    My point is--instead of trolling, try to make up your own damn mind.

    Heh, consistent 'location' of the back button, but not consistent behavior of it when you press it. ;) Reply

    Both my iPad and Android phone have their CRASH and freeze moments. Both suck in different ways. Reply
