ASUS Eee Pad Transformer Prime & NVIDIA Tegra 3 Review
by Anand Lal Shimpi on December 1, 2011 1:00 AM ESTBattery Life
With 39 hours to test I was pretty limited in what I could do when it came to battery life testing. I was able to run through two tests (one run a piece) and only in one configuration each. I wanted to see how Tegra 3 and the Prime fared in the worst case scenario so I picked the Normal power profile. Over the coming days I'll look at battery life in the other two profiles as well, not to mention run through more iterations of our test suite.
My bigger concern has to do with the malfunctioning WiFi in my review unit. For our video playback battery life test WiFi was on but not actively being used, those numbers should be ok. It's our general use test that loads web pages and downloads emails over WiFi and it's there that I believe things could've suffered a bit.
In both cases I saw around 9 hours of continuous battery life out of the Transformer Prime, without its dock. These numbers are a bit lower than the original Transformer but it's unclear to me how much of this is due to the additional cores/frequency or the misbehaving WiFi. The fact that we're within striking range of the original Transformer with the Prime running in Normal mode tells me that it's possible to actually exceed the Transformer's battery life with the Balanced or Power Saver profiles. That's very impressive for an SoC built on the same manufacturing process as its predecessor but with twice the CPU cores and a beefier GPU.
What I'm not seeing however is the impressive gains in battery life NVIDIA promised its companion core would deliver. I'm not saying that the companion core doesn't deliver a tangible improvement in battery life, I'm just saying that I need more time to know for sure.
That the Transformer Prime can deliver roughly the same battery life as its predecessor without any power profile tweaking may be good enough for many users. Both ASUS and NVIDIA shared their own numbers which peg the Prime's battery life in the 10 - 13 hour range. As I mentioned before, I'll have more data in the coming days.
Update - With a replacement Transformer Prime in house, battery life is looking a lot better already:
Update 2: Even more battery life results in our follow-up.

But what reason can you give for not getting an ipad? Too much software selection? Too great of an ecosystem? Too much wireless video streaming to your TV? Too high of resale value? Too easy to use?Curious minds want to know!

How about bad value for money? For the price of a 32GB Prime you get a 16GB iPad 2. It has roughly half the specs of the Prime: only 0.5GB memory, dual core processor v.s. quad core, lower resolution and screen size (which is REALLY annoying for watching 16:9 ratio videos, which is to say more than 1/2 shows/movies you can buy/download) and lack of expansion slots.In terms of software, iPad is smoother than android but at the same time you get a very limited browsing experience with iOS. I know HTML5 is the "future" but at the present is still dominant and will be for a while.
As for apps, whilst there are less app choice, It has a good range - you may have less choice in each department than iOS but you will always find apps suitable for your needs.
Build quality, at least for the prime, is also a lot better than the iPad's. Whilst both use aluminum instead of cheap plastic, the prime uses Gorilla glass rather than normal glass.
For $500, the transformer prime gives you a much, much better product. Apple products are very good and generally blows away low-mid range non apple products but when you compare apple's products to similarly priced alternatives, they just don't deliver acceptable quality for your money.
For example, a current generation MacBook pro 15" costs £1.6K. A HP 15" with virtually identical specs costs £800. The inclusion iOS does not justify a 100% markup on a windows PC. FOr £1.6k you can buy a laptop much, much more powerful than the £2k MacBook pro. The iOS may be better but is not worth £800. Furthermore to get full functionality out of a Mac you have to buy windows for bootcamp, which is another £120. By choosing a similarly priced alternative to apple products you "miss out" on an apple OS but gain much better specd products. I don't mind paying more for a better product but I expect the quality of the product to match the price and you just don't get that with Apple.

One criticism of the original Transformer was that the charging cable was too short. Have they addressed that issue with the Prime? If not - is a USB extension cable a reasonable solution to address a too short cable or is there an issue with the about of current being pushed down the cable to charge the tablet in a shorter time than the mini usb.Stas - Friday, December 2, 2011 - link
That is a fantastic screen! I'm very surprised and impressed.user777 - Sunday, December 4, 2011 - link
1) G3 USB stick testThere were a lot of questions regarding the G3 version of the tablet.
Is there a possibility to test any G3 USB stick on the Transformer Prime dock (example 50 USD/euro G3 usb stick from Archos G9)? It would answer all these questions.
2) Skype video call test
Skype is may be the most popular video app available for a lot of Android devices. Would it be possible to make a Skype video conference call test and confirm if the Skype app works with video on Transformer Prime?
3) MX Video Player test
I really like the MX Video Player which also has full support for multi-core processors, subtitles, mkv/m2ts/mp4/... file formats, etc. Is it possible to test MX Video player too?

The possibility to play multi format video files is indeed excellent feature of the Transformer Prime.Since the video file are quite large in size playing them from a home DLNA server via WiFi is important too (example Vuse torrent client DLNA server and playing by any third party DLNA client app like Skifta, iMediaShare, Bubble UPnP). Is it possible to test the DLNA video streaming of 720p/1080p videos?

for tablet/smartphone market, except Apple. Why? because it's so software/os dependent. With an open platform like Android/Window, it's very hard to harvest the extra resources.If you look at the PC market, the quad-core is for heavy gaming and server while the dual-core is the most generic CPU for every laptop/desktop out there. And that is with a matured market with matured OS and application.
I would doubt that Apple would go quad-core, but they are the only one can do it because they control both software and hardware. The rest? stick with dual.

Having a quadcore fast machine is good!However, there are not sufficient programs out there, really needing all that performance!
Most programs are smaller apps you can run with a single core running half the CPU speed!
And most games, 3D games run perfectly fine on a cortex A8 or A9 processor.
A pitty that software for Android is lacking behind!

That's the whole Asus Transformer Prime. It can use an integrated keyboard dock, to look much like a Zenbook. The hardware is similar.kamm2 - Monday, December 5, 2011 - link
"Scrolling is rarely as smooth as I'd like it to be via the dock's trackpad. Many times the gesture just won't register on the trackpad or the trackpad will detect my two fingers but it won't scroll."We have this problem with my wife's Eee PC netbook. It is very annoying. We are looking to replace her aging notebook and will not be buying one without scroll bars on the trackpad. The probably means no Asus. The trackpad is also hyper sensitive so it makes accidental touches while typing a nightmare. There seems to be no sweet spot when adjusting the sensitivity. This is in contrast to the trackpad on her first generation Eee PC which is excellent.
