Battery Life and Conclusions
My battery testing with the Xiaomi Mi Pad 7.9 is a bit limited for now as I was only able to run our now standard PCPer Wi-Fi test. In this test, display brightness is normalized and we run a script which cycles through websites every 30 seconds.
With a result of just over 9 hours, the Tegra K1 tablet was able to pass up that of the Tegra Note 7, and nearly matched the ASUS MeMO Pad 7 using the Intel Z3745 Atom processor. The ASUS Nexus 7 (2013 edition) runs for a more impressive 11.5 hours, easily overtaking the other Android tablets we tested.
This graph is a bit more interesting, as it presents a calculated estimate of power consumption of each tablet, including the SoC, memory, display, etc. These numbers were calculated by finding the total battery size of each tablet (in Watt-hours) and then dividing that by the actual number of hours the tablet ran in our testing. Obviously this result isn't going to be 100% accurate, and takes into the calculation the other components in the tablet, not just the SoC. Still, it's an interesting look at the overall efficiency of the Tegra K1 platform.
In this graph, a lower number is better, as it indicates how power is being consumed. The lower this number, the longer the battery in the device would last. Even though the Tegra K1 is able to hit 9 hours in our Wi-Fi browsing test, it clearly requires a much larger battery to do so. The K1 comes with a 24.7 Whr battery; the Nexus 7 only needs a 16 Whr battery and lasts more that two hours longer.
I have a lot more battery testing that I would like to do with this device and a couple of others shipping very soon. Hopefully we'll be able to investigate gaming-time as well, something that I think needs to be considered more heavily as NVIDIA starts to target the gaming angle (even more exclusively) for its upcoming products.
Closing Thoughts
The Xiaomi Mi Pad 7.9 is an interesting product that will have little impact on the US market. As a device that is not intended to be imported here, it is really just an educational venture for us to test it and evaluate it. Even so, the results were damned impressive and the performance of the Tegra K1 SoC really came through in both the CPU and GPU results. By integrating a full Kepler SMX in the design, the graphics performance of the Mi Pad is unrivaled in the tablet market. However as it stands now, there are a very limited number of applications or games that can even truly show the performance the K1 can offer. As the K1 implementations increase though, that will likely improve.
I paid $344 for this unit before shipping costs, off of AliExpress.com. Do I recommend that our readers go out and make the purchase as well? Likely not, but for those that are curious and demand the latest technology today, it's not a horrible investment. I think I can get away with telling you that other tablets using this SoC will be available pretty soon domestically, so you should probably wait for something you can pick up on Amazon or Newegg.
My time with the Xiaomi Mi Pad 7.9 has been fun. I only hope that NVIDIA and its partners can find a better way to highlight its benefits with games and software.

Let’s hold on and see if they
Let’s hold on and see if they have more success with this one. Historically, they have been too far on the higher performance / low battery life side of the power tradeoff to really get many phone and tablet makers to use their chips. I have never really heard of Xonami – they need design wins from Lenovo or HTC would be more impressive.

Everyone who read tech sites know by now than Nvidia’s own Tablet comes at 22 of this month and it will be available in US in the 29th and in Europe from August 14. If they didn’t, well, Google is a few clicks away 😀

Same problem we see with all
Same problem we see with all of nvidia’s soc offerings. High power consumption vs the competition.
The review also is using last-gen competitor’s soc based products against nvidia’s newest.
Unfortunately not much will change in the mobile space with nvidia relegated to being a very small player gasping for any share.
You’re so wrong.
Xiaomi
You’re so wrong.
Xiaomi already sold out their entire first batch of MiPads with Tegra K1 and is on track to sell millions of them.
The next-gen Google Nexus tablet will use Tegra K1, that alone makes it very high volume product. Niche my ass.
But I guess haters gonna hate successful companies like Nvidia.
The -rumor- of the next Nexus
The -rumor- of the next Nexus using Tegra was just that, a rumor. Has since been debunked.
Try not to make up fallacy predictions on sales of an unknown tablet maker from China as well, please.
nvidia is a very tiny player in the mobile space and that is not going to change. kudos to them on making a good soc, the reality is that is not enough for them to see any real success, as has been the case since tegra’s first launch.
nvidia is a very small fish in a pond filled with sharks like Qualcomm and Samsung.
I assume you are either an nvidia stockholder or simple fanboy, perhaps a mix of both.
Go back to AlwaysInnaccurate,
Go back to AlwaysInnaccurate, Charlie.
Nvidia will sell millions and millions of super power efficient Tegra K1 SoCs and there’s nothing you can do about it.
If they can get these tablets
If they can get these tablets running Steam OS they can sell, but Nvidia’s CEO loves the control and closed ecosystem, and that will blow up in his face! The K1 may not be as power efficient as the other tablets, but that may be more a factor of the GPU, and less a factor of the CPU. Graphics wise the K1 is probably the best, but the PowerVR wizard, with hardware ray tracing, has yet to make it to market on any SOCs, and I hope it can get some design wins. Apple is going to release the A8, in a few months, but Apple needs to get a pro tablet, that can run the Full OSX, and the graphics programs that run on OSX, otherwise the market on the highest end will continue to be with M$, and Intel, overpriced even more so that Apple. These devices have to be available for more than just gaming, the K1 especially, would make a fine low cost graphics tablet, if it came with a full Linux distro.
Yes they sold the first 50000
Yes they sold the first 50000 to Chinese resellers, who expect to make a good profit on eBay from those. Xiaomi didn’t sold out to individual customers like you(I guess) and me.
Nvidia is moving away from
Nvidia is moving away from smartphones and maybe later tablets. I huge gpu advantage, is no advantage at all, on a tiny screen.
Nvidia is moving with Tegra to Chromebooks, notebooks, AIOs, convertibles and eventually they will come to desktop, with a full ARM based platform, where you would be able to add one or more hi end Nvidia cards and have the perfect Steam machine.
They are tiny in the smartphone arena, but they are going to become a big threat to Intel and Microsoft in the future. The funny part here is that Intel will desperately need a strong AMD alive and kicking in the GPU market, or Nvidia will grab all the gaming PC market for themselves, with the help of Steam OS.
How about some throttling
How about some throttling tests? Going by your power consumption testing this chip must be really hot and unable to perform 100% for longer than 5 minutes.
This chip isn’t suitable for a tablet and much less for a phone.
Are there some Charlie’s
Are there some Charlie’s disciples hanging around here posting dribble infused rants and comments?
I’ve just seen a glimpse of what this SoC can do and is remarkable, should’ve removed any doubts. It’s a shame that still people don’t believe what’s in front of their eyes.
We all seen what’s this. A
We all seen what’s this. A power hungry chip with overkill GPU performance. Phones are out of the question because of the power consumption and the lack of connectivity. If Tegra 4 wasn’t good enough for phones this is even worse.
Nvidia just can’t read the mobile market at all with software so far behind. Having the power consumption in check with somewhat less GPU power would have made a way better SoC.
Anandtech does throttling testing in their reviews so we will find out tomorrow.
Xiaomi actually has a great
Xiaomi actually has a great track record of updates. They were into software before hardware.
I just got a Xioami Mi3 phone, and the price/performance can not be beat. Their android implementation is also pretty slick, and I’ve actually flashed it into an older android phone after playing around with the Mi3.
The only question in my mind is after sales support. Their online software support is pretty good though.
Call me when they get a full
Call me when they get a full Linux distro running on this tablet, With Android it is just a toy! Get Steam OS running on it! Nvidia if you want this to be a real factor in the tablet market, do not go all in with Android, get some tablets running full Linux and graphics programs, and widen the market for the K1, I hope they get the Denver K1 version into tablets, and some real OS distros running on them.
If there is one thing K1
If there is one thing K1 proves is that TDP/power consumption is still the single most important factor deciding if mobile chip succeeds or fails in the market. Powerful graphic sound nice on paper, but at the end of day all it gets you is heavier and hotter pad/phone with shorter battery life.
Lets be serious, pads are only for causal gamers, and they typically don’t give half a steaming turd about graphic performance of their games. Candy crush and gazillion tower deference clones don’t need good graphic or compute, so K1 advantage is completely wasted on them. But on another side those casual gamers will not appreciate shorter battery life or warmer pad, nor are they likely to appreciate higher $ tag that comes with nvida chips.
Also why do OM still make pads without GPS? Who would buy pad without GPS? $300+ for 8”pad without GPS, they must be insane.
The next step for Xiaomi? To
The next step for Xiaomi? To certify its products to Europe and start sending weekly containers of products to implement directly from us through a local distribution company, the brand choice and many dealers are waiting it.

Had the Nvidia K1 shield Tab.
Had the Nvidia K1 shield Tab. Really nice but man did it ever suck down the battery. Paid $300 for 16.. bought the Mi pad just a tad over $300 for 64gb. Little bigger screen battery life is so much better. It has a little bigger battery.
Yes the Nvidia Shield tab has allot going for it but for ME..I could not get around the battery life. Playing games.. be lucky to get 2-3 hours. Yes that bad. Gets REALLY HOT! Worse then the Tegra 4. Mi Pad gets just as hot. But I really like it better.

How to Root the and install Custom Recovery on the Xiaomi Mi3
As a mipad owner for me
As a mipad owner for me personally the main trick is the 4:3 retina screen. I don’t play games anyway on the tablet, mainly use it for internet, mail, pdf/ebook reading. And for that the screen is awesome.
And about the K1, sure… it’s prolly overkill in the gpu department (it at least is for me) but it’s still one hell of a chip if you don’t use it at 100% all the time and I sure don’t.
It has the power when needed for me can chill pretty muchthe rest of the time. As a result I have never felt it as hot or anything.
As far as support goes, still quite a bit of work on the software department but very usable already and they release a weekly developer rom update so that’s pretty awesome as well.
