NVIDIA Shield Review: At the Crossroads of PC and Mobile Gaming
by Brian Klug on July 31, 2013 12:14 AM ESTBattery Life
NVIDIA's Shield includes a 28.8Wh battery, which is large for a device its size but small compared to what you'd find in a 10-inch tablet for example. The good news is that it only has to power a 5-inch 720p display, which makes the choice of battery size quite nice. Since Shield is a fully functioning mobile device, we put it through our current battery life suite. Normally we'd start with our WiFi web browsing test, but given the target market for Shield I figured starting with our 3D rundown test made the most sense.
Here we have a loop of the Egypt HD benchmark, capped to 30 fps, running on all of the devices with their screens calibrated to 200 nits.
Shield manages just over 6 hours of use on a single charge, putting it up there with some of the best mobile devices we've put through this test. Being able to support 6 hours of locally rendered gaming without plugging in is pretty decent I'd say.
Video decode is also quite important, especially when you consider the use case where Shield acts as a remote display and controller for games rendered on your PC. In that case, the GPU is mostly powered down and only the video decode block is used to display what's being rendered on your PC. Our video playback test might be a good simulation of this use case. Our test remains unchanged from previous tablet reviews. Here I'm playing a 4Mbps H.264 High Profile 720p rip I made of the Harry Potter 8 Blu-ray. The full movie plays through and is looped until the battery dies. Once again, the displays are calibrated to 200 nits:
Tegra 4's video decode engine combined with a tiny 720p display and a 28.8Wh battery results in awesome battery life here - almost 19 hours on a single charge. If you can deal with the small screen, Shield might make for a good companion on long haul international flights just for video playback.
Finally we've got our standard web browsing battery life test:
We regularly load web pages at a fixed interval until the battery dies (all displays are calibrated to 200 nits as always). The differences between this test and our previous one boil down to the amount of network activity and CPU load.
On the network side, we've done a lot more to prevent aggressive browser caching of our web pages. Some caching is important otherwise you end up with a baseband/WiFi test, but it's clear what we had previously wasn't working. Brian made sure that despite the increased network load, the baseband/WiFi still have the opportunity to enter their idle states during the course of the benchmark.
We also increased CPU workload along two vectors: we decreased pause time between web page loads and we shifted to full desktop web pages, some of which are very js heavy. The end result is a CPU usage profile that mimics constant, heavy usage beyond just web browsing. Everything you do on your device ends up causing CPU usage peaks - opening applications, navigating around the OS and of course using apps themselves. Our 5th generation web browsing battery life test should map well to more types of mobile usage, not just idle content consumption of data from web pages.
Once again, excellent battery life from Shield.
NVIDIA ships Shield with a 10W (2.1A) power adapter, capable of completely charging Shield in 5.45 hours:

Is it possible to run a battery life test with a H.264 encoded video being played back AND streamed over Wifi somehow? I feel like that would be a better simulation of the battery life under PC game streaming without having to sit there and play the game outright until the battery dies (although I'm sure that would be a lot of fun =))Crono - Wednesday, July 31, 2013 - link
The problem with this kind of gaming device is that it's guaranteed to be selling well only in a niche market.It's too big to be portable, not powerful enough to be a console or desktop killer, and not versatile enough or the right form factor to be competitive against tablets. And then there's the obvious fact that mobile gaming is being dominated right now by smartphones and smaller tablets and more traditional handhelds.
The comparison picture tells a lot: larger than an Xbox 360 controller is too large.

Desktop killer??Did you even read about this device at all??
This is a desktop EXTENSION in the best way possible

How is it not versatile enough to compete against 7 inch tablets? If you can spare those 2 inches, you get:- It's probably going to have more power than any 7-inch tablet released in the next year.
- Excelente battery life.
- Kickstand/gamepad
- Great speakers (except from the BB Playbook, I haven't seen a 7-inch tablet with decent audio).
Weight is the only major disadvantage over a 7-inch tablet.

Crono's point is that this device is a mobile gaming device. It won't replace a tablet, a smartphone, a laptop, or anything with a virtual/physical keyboard. It's most direct competition is the DS/Vita, which have much higher quality game libraries.So who's going to buy this thing? Enthusiast gamers with a need for mobile gaming that aren't satisfied with their DS/Vita. That's a pretty small market these days.

It obviously won't replace a smartphone or a laptop, not even 9/10/11 inch tablets, but I can imagine people buying one of these instead of an iPod Touch, iPad Mini or a 7 inch Android tablet. It offers similar functionality for a similar price. Again, only if the weight is not too much of an issue.Jumangi - Wednesday, July 31, 2013 - link
It doesn't offer anywhere near the functionality when you take into consideration the form factors with something like the Nexus 7. And saying it will sell over an Ipad mini/ Wow the bizarre reality some people live in to justify weird tech.PNN - Wednesday, July 31, 2013 - link
You're not getting my point. Bye.Spunjji - Thursday, August 1, 2013 - link
Form factor is a huge consideration too. You will not fit this in a jacket pocket or small bag as easily as any of the devices you mentioned, and you're certainly not going to use it comfortably with one hand. I'm not saying your point is entirely invalid, but you're arguing this thing will fit into niches where it's not an ideal match.darkich - Wednesday, July 31, 2013 - link
"much higher quality game libraries" ..oh man what a load of horse s!it.You are obviously completely ignorant about iTunes and Google Play games.
There's still so much prejudice going on about that among you pc dinosaurs.
Let me break it down:
The vast majority of Games on google Play cost up to 7$
