Asus Transformer Prime TF201: A Tablet With A Higher Calling

Battery Life And Recharge Time

After running the Transformer Prime through our standard suite of battery tests, we decided that it's able to hold a respectable charge, ending up close to the middle standard battery tests, we decided it holds a respectable charge, falling close to the middle of the tablets we've tests. And although the device doesn't break any battery life records, we were pleased with its quick charge (0-90%) time. The break-down is as follows:

At maximum brightness, we measured just north of four hours doing some general Web browsing.

When we dial brightness down to 200 nits, creating a more controlled environment, we are able to extend battery life an additional 15%. All of Apple's tablets far exceed what we saw from the Transformer Prime in this workload.

When we turn off Wi-Fi, it immediately becomes clear just how much of an impact networking has on the Transformer Prime's longevity. We're able to get more than 10 hours of battery life from the tablet playing back H.264-encoded video, so long as the wireless radio is off. That works out particularly well for long flights with no Wi-Fi.

You're not able to game for as long on the Transformer Prime as you could on an iPad. But it's worth noting that we're using a pretty intensive game for benchmarking. A simpler title like Angry Birds should afford you a longer charge.

Recharging is where things really start looking up for the Transformer Prime. It's able to hit 90% in just two hours. A full charge takes two hours and 50 minutes. 

Those are almost exactly the same results we got from the original Transformer. Both Asus tablets can achieve a decent charge over a lunch break. Compare that to Apple's new iPad, which needs to sit plugged in overnight if it's completely depleted.

    Is this a joke? Wait for the new iPad to come out and then review the Transformer Prime? Why didn't you review it sooner? Did Asus miss a payment or did Apple give you a little extra to keep a lid on it?

    Wake me when it is running Windows on a x86 CPU so I can install whatever I want for free.

    Because we didn't have it sooner.

    I was thinking of getting this until I caught wind of the Transformer T701.
    I think the 1080p display is worth the wait.

    ... that thing with the splash effect... i do believe, that it iz a program issue... 3rd gen iPad haz power to burn... you can program some splashes... it's like M$ say, that, to play crysis and see the rays thru treas, you needed vista and DX 10... it turned out, that it waz a tweak, that enabled it on XP too... and i believe, if apple will implement some open standard of some physics engine, like Bullet Open Source Physics, all of the open standard devices will benefit, android and iOS alike... and nVidia physx will be not relevant... to program some separate android+nVidia version of a game? ...when there is many different android devices, that don't use Tegra? ... it could end for nVidia, like it ended for 3DFX with there glide engine... 3Dfx waz killed by OpenGL and DirectX... 3Dfx's Glide waz visually superior, but OpenGL and DirectX helped then ATi and nVidia to go multiplatform and to the masses...
    ... so, my point waz... prime is a nice thingy, but, if there are proprietary stuff on a open platform, like android... i don't believe, that Tegra can get some momentum without going open source... the question is... how big is the Tegra's market share on the android platform? ... and... is the market share for Tegra so big, that they can insist to use there proprietary things?...

  • "While the Transformer Prime supports output over microHDMI, it cannot push 1080p through the wire" ...When using hardware decoding, Transformer Prime actually pushes true 1080p-video to the television (..while the tablets screen remains unused = black). As an owner of TF201, I can confirm this.

  • In Italy Asus decided not to give the free dongle, because they say that it was selled as a localization system, and not a GPS, therefor, they will not help us improve our tablet experience. Since the prime doesn't have a 3G connectivity, I don't think the GPS is that important, also, a 10" GPS is quite annoying. I prefer to use the phone. Great review by the way. Although I don't trust benchmarka, nor asus ICS updates. At the biginning the wi-fi was working great, no overconsumption of power, now my battery drains in hours.
