Battery Life
The Dell Venue 8 7000 is only rocking a 21 Whr battery, but the use of an OLED screen can complicate things. While an OLED uses only around 40% of the power of a traditional LCD in dark scenes, it can use as much as 3x the power when you are looking at an all-white image. Averages for the majority of content ranges from the 60-80% mark though, giving OLED a power advantage over LCD in general. Intel’s 22nm process technology is easily the most power efficient shipping today, and Dell and Intel collaborated for a long time on this product to really perfect power consumption and user experience.
First up is our PC Perspective Wi-Fi browsing battery test.
The PC Perspective Wi-Fi browsing battery life test uses a custom script on live web pages to cycle through a set of 30+ pages. We are using desktop-class webpages here though obviously Flash isn’t a factor. On a 30 second rotation, you may notice that some of our results are lower than manufacturer estimates; the key is to compare the devices relative to each other.
Things are looking up for the Dell Venue 8 7000 already with the best web browsing battery life of the four tested tablets. (The iPad Mini Retina result didn’t complete and continues to fail/crash during testing.) At over 9 hours of battery life with a 21 Whr battery, Intel has clearly tuned this iteration of the Z3580 platform for this goal. Second in our testing is the iPad Air 2 with a larger 27 Whr battery, but comes up nearly 2 hours short of the Venue result. Both of our Tegra K1 devices, the SHIELD Tablet and the Nexus 9, have significantly lower scores here, pulling in 6.5 hours each.
For our gaming battery life tests we use the GFXBench 3.0 integrated battery benchmark that loops through the T-Rex scenario 30 times and records battery drain to build an accurate estimate of total battery life. We start the test with the batter under 90% capacity but over 50% capacity.
Even though the Dell Venue 8 7000 has fairly low graphics benchmarks in our testing, the battery life for gaming is quite good. One of the benefits of a lower power consumption part is that you can get more livelihood out of that 21 Whr battery. And if the gaming performance is “good enough” then the result is positive. The iPad Air 2 comes in second with a 3.86 hour rating with the Tegra-based tablets coming in well behind. We have plans for some more interesting gaming testing in the near future that might shed a better light on real-world gaming and battery performance so stay tuned for that.
For our video playback battery life test we are using an Android application called simply "Video Looper" to loop through a 2 hour 4 Mbps H.264 video. We use the simple art of time lapse photograph to record the tablets playing the video and note the shutdown time for each unit. Screen brightnesses are again normalized at 180 lux.
We didn't get a chance to run the iPads through this test yet though we will be sure to do so for further reviews, but the Dell Venue 8 7000 once again proves that faster isn't always better. It is capable of a full hour more video playback than the Nexus 9 (that has a 4 Whr larger battery) and more than 5 hours more (!!) than NVIDIA's SHIELD Tablet with Lollipop.

Look ’em right in the eye,
Look ’em right in the eye, say “Flagship? 16GB?” and make them eat the damn thing.
I’ll take a look when if and when they ship a 32GB model, but they should never have shipped a 16GB model.

I don't really disagree, but all flagship tablets at least come in a 16GB variety.

Yeah, I know. It’s just so annoying. Fabulous screen, fast CPU, plenty of RAM, decent battery life, everything is good…
And then the same 16GB of storage as we had in 2012.
Kind of agree there. Does the
Kind of agree there. Does the SD card slot not alleviate this?
To a degree.
The problem is,
To a degree.
The problem is, Android 4.4’s support for removable storage is… Not great. I have an Xperia Z Ultra with 16GB internal and a 128GB Sandisk micro SD card.
The SD card is brilliant. I have a ton of music on there, all the recent episodes from podcasts I follow (including yours, of course!), and a nice collection of audiobooks.
But my apps have to live on the internal storage. So do all my Kindle books.
I’ve been very selective about which apps I install, but I’m down to about 3GB of space on the internal storage. I have 50GB free on the SD card, but I can’t use it for that.
Android 5.0 might be better with SD cards, but I only have it on my Nexus 7 so far, so I can’t test that.
Given that we’re talking about a $400 device, and the price difference between 16GB and 32GB of decent quality Flash storage is $10 retail – and that it would more than double available space because at least 4GB is used by the OS and restore volumes – this ongoing insistence on providing inadequate storage even on flagship devices is really starting to piss me off.
Good point. I’ve lived that
Good point. I’ve lived that too. And considering that they can put 512GB on a micro SDs and M2s, there is little reason why they can’t build that much into these.
Also, considering that this is a recent “flagship” release I’m assuming that the MicroSDs supported are UHS-IIs. I think SDIO may cover the whole lot.

its a pretty steap price for a tab without lte, only 16 gb onboard storage and a unpractical design. i use my tab only in landscape mode and the single bezel on this tab looks unhandy.
the only plus on this tab is the screen.
but lets talk about the most disappointing part of this tablet. it comes with an outdated version (4.4) of android.
the bottom line for me is:
-expensive
-outdatet software
-lack of featuers
-no ergonomic way to use it
for the same price, you can get a nvidia shield with lte, 32 gb storage, more gpu power, up to date android 5.0.1, a bezel on all sides to get a grip, faster charging times, yes the dell loads rly slow! only the screen on the shield is not so fancy.
so, no.
wont buy. 400 for only a nice screen is too much dell.
you can get for around 230 an
you can get for around 230 an memo pad from asus http://www.asus.com/Tablets/ASUS_MeMO_Pad_7_ME572CL/specifications/ also has lte and most of the stuff you need, well not such a fancy screen, also an outdatet android, probably a bit slower in performance and so on.
also the Lenovo Tab S8-50L LTE http://shop.lenovo.com/gb/en/tablets/lenovo/s-series/s8/#tab-features way less expensive and comes with an lte modul for about 230.
so, a fancy screen costs 170 bucks?
i cant rly understand the excitement.

In many cases, a tablet and phone is more about the experience and build quality than specs. Still, I am trying to get these tablets in currently! Thanks for the heads up!

Great review Ryan, and yet another example of why I always check PCPER before buying a piece of tech. Was there any indication that we might expect an LTE variant? With LTE, 32GB and a 256GB SD, this could contend with laptops!

Almost all tablets start 16GB honestly though. I would agree Dell needs more options.

Do you know who supplies the OLED screen? Was it Samsung? The Samsung Tab S are also OLED and have been reviewed as having the best display out of the tablets currently available. The other internals are a bit more dated however.
I believe another review
I believe another review mentioned it’s probably the identical screen as what is found in the Samsung.

This review was almost enough
This review was almost enough to get me to purchase this since I’m looking for a new small tablet for my wife after her Memo Pad 7 gave out (just stopped charging), but the Amazon reviews for this are horrible. Great review though … thanks!

Purchased this last night
Purchased this last night based on your review.
I’ve had probably a dozen different tablets over the years starting with the first Tegra 2 tablet that I could find (Viewsonic G-Tab) which had the most horrible screen on any device I’ve ever seen.
This one, by contrast, has the best screen I’ve seen on any device. The 3D cameras are uncalibrated out of the box and aren’t all that accurate for the 3D functions, but the software assures me it will get better as I take more photos. It’s not the fastest tablet I’ve used I don’t think, especially in the GPU department, but it’s more than adequate. The build quality is as good as any other I’ve had and better than most. Only the ASUS 10″ tabs come close in comparison to ones I’ve owned.
What it does well, it does VERY well. What it doesn’t, it does well enough to make me believe it’ll keep the top spot on my tablet list for a while.

I felt this thing at Best Buy, and it is absolutely fantastic to hold. Very thin and it feels like a piece of metal.
My only disappointment is KitKat rather than Lollipop, but I understand the optimizations that must happen. After using Lollipop on my phone now since it was released, KitKat feels like something of an eyesore.
Great review Ryan!

32G came out this week. I am looking forward to mine arriving 🙂
Having used the 32G version
Having used the 32G version now for several weeks I can say I really really am liking this tablet. Gorgeous screen..it took a couple days to get used to the button location on the left side, but I am fine with them now. Very responsive. I would like to see lollipop soon, but it’s easily my favorite tablet.
Anyone know if the Venue 8
Anyone know if the Venue 8 7840 is fitted with Gorilla Glass? Or anything similar to prevent scratches and breaks?
The tablet scene seems a bit
The tablet scene seems a bit quiet lately outside launches of some larger ‘Pro’ models. I guess tablet sales are a bit soft globally. My 2011 iPad 2 was gimping too badly so I just bought this Dell Venue 8 7000 32GB. Great price discounts are had on it now that it is a year old and it now comes with Lollipop 5.02 that immediately upgrades to 5.1. I would expect an Android 6.0 Marshmallow upgrade over the next 3 months.
Having owned a tablet for years I’m somewhat past the experimentation thing with a gazzillion apps and games and quest for the ultimate specs. I now am more a user of the core types of apps someone uses with a tablet. As a result, my main goals in a tablet are great screen display/readability, snappy and fluid transitions, smooth browsing/reading, smooth video streaming, excellent build quality, excellent battery life, excellent physical usability and overall visual coherence.
This tablet really nails it on most dimensions I’m looking for. As someone else mentioned, where it misses dead center, its definitely good enough. The revue above does a good job of capturing the nuances. I’m sure over time Google will make the Android OS more complex, forcing hardware end-of-life… but for me, Lollipop + Venue 8 addresses all my needs in a tablet already. Marshmallow, if/when it arrives to the V8, will only further improve the SD card functionality in this device. I’m hopeful Dell WON’T keep forcing OS upgrades to this device, making it gimpy, like Apple did to my iPad 2.
