Battery Life

Battery life is obviously one of the most important aspects of a mobile device. With flagship tablets, users have come to expect that their device will give them ten hours or more of usage on a single charge. The Venue 8 comes with a 5,900 mAh (21Wh) battery, and Dell rates it for ten hours of usage.

Web Browsing Battery Life (WiFi)

In our WiFi web test, the Venue 8 manages just over nine and a half hours, which is fairly close to Dell's recommendation and competitive with the battery life results from the iPad Air 2. The Nexus 9 does hold a lead of a little over one hour, but in general any modern tablet that isn't the Stream 7 or a similar tablet is going to last you through the day adequately.

Video Playback Battery Life (720p, 4Mbps HP H.264)

In our video playback battery test the Venue 8 really shines. The lower APL of films compared to black text on white webpages allows for a battery life of 12.77 hours which beats out both the iPad Air 2 and the Nexus 9, with a significant lead over the latter.

BaseMark OS II Battery LifeBaseMark OS II Battery Score

In BaseMark OS II we see that the Venue 8 does very well in both the overall time running as well as in the score given by BaseMark. Even with the CPU sustaining a high level of performance throughout the test, battery life is ahead of every other competing tablet.

GFXBench 3.0 Battery LifeGFXBench 3.0 Performance Degradation

In GFXBench we see a similar situation to BaseMark, but this time with the focus on the GPU. The Venue 8 takes the top spot in battery life, but comes out slightly below the middle of the results for its FPS in the final run of the test. Its FPS drops from 20.26FPS to 18.83FPS which means that there isn't much throttling going on with the GPU, but it also isn't putting nearly as much GPU power into a tablet as Apple, NVIDIA, and HTC are in their offerings.

Charge Time

Charge time is the other half of the battery life story. If you can charge a device very quickly, having a slightly shorter battery life may not be much of an issue. Conversely, an extremely long charge time can leave a device tethered to a wall for long periods even if it had great battery life while it was still charged. The Venue 8 comes with a 5V 2A charging block in the box, and it fortunately does not have any coil whine issues like I've experienced with other recent devices with high wattage chargers.

Charge Time

The Venue 8 does well in our charge time test. At 2.78hrs to reach 100%, it charges even quicker than many smartphones. There's not much else to be said beyond that Dell has gotten the best of both worlds with great battery life and a short time to recharge that battery once it's depleted.

    1. comfort and ergonomics (seating position, not having to hold it up, big screen and audio without spending even more $$$ in wireless gizmos)
    2. speed of writing and clicking when browsing the internet
  • WereCatf - Thursday, March 12, 2015 - link

    As for comfort: I'd say it's actually a plus for tablets that you can use them in all sorts of positions and not be restricted to seated positions. As for "big screen:" not all activities require a big screen. If you always insist on doing everything on a big screen then that's on you, but obviously many people don't. Writing is faster on a proper keyboard, sure, but I don't see how clicking is any faster.

    Besides, nothing you said actually answer the question I asked: why is using a tablet specifically at home so ridiculous compared to using it elsewhere?
  • darkich - Thursday, March 12, 2015 - link

    Thise arguments are utterly ridiculous.
    Have you ever actually used a tablet?

    An 8" tablet is PERFECTY usable in a sitting position, its screen provides a perfectly natural focal area size from that viewing distance, when held on top of the lap.
    Reading articles is in fact far superior than on a laptop even in that position since:
    1}) articles are usually formatted towards visual focus of the eye(columns) and portrait screen of a tablet is a perfect fit for a column.
    If you still fail to see the obvious and dont get why tablets are far better and convenient way for reading than a laptop is ,let me ask you - how many books and magazines have you read on a laptop??.
    2) tablet screens are superior to laptop(unless you want to compare a $1300 laptop with a $400 tablet) screens in terms of quality.
    3) tablet is incomparably more manageable and confortable to handle than a laptop due to vast weight and size differences.
    4) tapping and swipping >>> using a touchpad for scrolling and clicking

    I've read a ton of pdfs (books and papers) on a laptop. I tend to agree with your points, however, one thing a laptop has got going for it is the screen size. On my 15" MBP I can display two pages at a time. Alternatively, when a text is really dense (some papers), on a 8" tablet the font is simply too small to read comfortably without zooming in all the time (with your zoom resetting every time you turn a page.
  • darkich - Thursday, March 12, 2015 - link

    Yeah I don't disagree with your points either, all you say stands but doesn't counter what I said.
    For some complex and rich context, a top notch laptop like MBP is a natural fit, but overall, Internet is about reading, and for reading a tablet will always be a more natural fit than a laptop.

    It is no coincidence that devices specialized for reading have 6" screens, and are about as light as a magazine.
    I actually by far prefer to surf on my Note 3(despite having an 8" tablet also) ..all context can be easily managed with one hand, and the screen is just the right size to cover the visual focus from one ft distance.

    Ah. You're on 'our side' lol. I misread. I love my Note 4 too. But pick up an iPad mini retina. The second iteration is a bargain right now and it's not much heavier than your Note
    But it's a HELLUVA lot easier to read whe your eyes get tired (I'm 44 & retina, HiDPI displays have changed everything for me when it comes to Legibility & Portability/Hand 'Hold-a-bility'
  • akdj - Friday, March 13, 2015 - link

    Need to look at it differently. I'm with you as an rMBP owner myself and LOVE computing again...after three decades, HiDPI is phenomenal
    That said, as darkich mentions...its a 'comfort' thing
    The iPad Air2's display is phenomenal. The horsepower is finally here and in MANY cases, it's a perfect 'home' computer. Facebook, Twitter, email, SMS MMS, pics, reading, surfing and gaming ALL significantly more 'easy' to do with a one pound 6mm tablet without the keyboard in the way! While the last part may be one of the dislikes you've got with tablets ...you can always get a keyboard case for a hundred bucks ...that said, after time with an iPad you can type quick. Respond fast and get back to what you were reading, watching or playing. A laptop while hella more powerful invites distractions while 'reading a magazine, book or doing a crossword puzzle'
    IMHO, it's always made me curious why others 'want' multitasking on a tabket OR user accounts. The former ...I've also been a Galaxy Note owner and currently use the Note 4 for our business, it's multi tasking system is still very flawed and much like in this article ...it's Google that isn't paying attention to their UI layouts pixel for pixel on individual devices
    Probably an impossibility I know me the latter...a first world deal, but for my family our tablets, whether my son's iPad mini, wife's Air, employees' iPads or my own are VERY personal devices set up the way you're looking to set them up with your icons and apps distributed in the fashion you prefer
    If you're unable to realize the benefits of tablet computing you're 'working too much!' Enjoyment, recreation and pleasure are how I use my iPad at home. On the Job site, it's all business! (& they're VERY capable devices now, today in this incarnation as a productivity piece too! $10/month and you've got 5TB of storage on OneDrive with a free word processor (Word), spreadsheet creator or editor (Excel) and a crappy presentation program in comparison to Keynote. Called PowerPoint;). Five tablets. Five computers. Mix n match as we do and it's a bargain!
    Not to mention making music, editing photos, video work flow or entertainment. Games for a buck or two. Five or ten for the big ones and some IAPs the kids can 'earn'. Lot better than dropping the same amount on a console and $60/pop for a game they don't enjoy

    I'm comparing a 13" MBP to say, a tablet like the Air 2 or retina mini. I actually find my laptop more comfortable than my tablets when sitting (couch or otherwise), eating (kitchen table), on the toilet (I have a small table in the washrooms dedicated for the placement of tablets and laptops).

    1) on my MBP, books and magazines are okay, and can match my tablet's viewing experience only if the app/program im using is optimized for viewing on a laptop. That being said, I prefer my tablets in this category because of the "curated" views books and magazines have done for the reader.

    2)screen speaks for itself, but one thing to note is that for laptops, u can open a swathe of articles a lot easier and faster than a tablet can. If I'm spending an hour catching up on the news or some tech event, I could easily open 10-20 tabs for articles and related articles much faster than my tablet.

    3) sure, there's a weight and size disadvantage, but there's also a keyboard and screen advantage

    4)for my MBP, scrolling is a pretty easy two finger affair, which doesn't require me to reach my tablet each time. As for switching browser Tabs, I just use the keyboard short cut (same with closing/opening), and keyboard shortcut for switching programs. Zooming for text to fit to size is also an easy affair with "reader" setting on safari (removes adds, reformats text) for those websites with terrible layouts, or I could just double-tap my trackpad on the text I want to read and my browser automatically adjusts the zoom to fit my screen.

    I'm not out to promote apple per say, but once u figure it out, their UI for some things is pretty amazing. It would be a nightmare to do the above in Windows IMO
  • Sushisamurai - Sunday, March 15, 2015 - link

    I do prefer my tablet in some scenarios, such as lying down in bed (I have a canter lever tablet holder thing), and when my laptop doesn't fit the area required, like my current predicament of replying to this while in my bathtub

    "The Venue 8 has an LTE variant, but most tablets operate purely over WiFi." Hmmmmm . . .
