Battery Life

With no native email client we had to modify our general use battery life test a bit for use on the PlayBook. Here we're just playing MP3s and going through our (non-Flash) web browser battery life test, there's no active email checking in the background (which is present on both the iPads and Xoom in this chart).

General Usage - Web Browsing, Email & Music Playback

General usage battery life, at least today, appears to mirror that of the Motorola Xoom. At 7.66 hours of battery life the PlayBook is noticeably worse than the competition, and that's without checking emails in the background as well. Over 7 hours is still enough to get you through the majority of the work day, but heavy users should plan on charging the PlayBook at least once a day.

Video playback is a bit better. Running the same 720p base profile test as the rest of our tablets, the PlayBook managed 9 hours of video playback - comparable to the Xoom.

Video Playback - H.264 720p Base Profile (No B-Frames)

I also threw in battery life when running a 1080p main profile clip, something the other tablets can't do. There is definitely a negative impact on battery life for more complex videos, so keep that in mind if you plan on taking advantage of the OMAP 4430's flexible video playback support.

    "I've complained in the past about the input problem on tablets, and I do believe it's actually worse on the PlayBook thanks to its cramped screen resolution."

    While higher resolution might help a little by allowing text to be slightly smaller while keeping it legible, this is really about area not resolution. You can't make the on-screen keyboard or address bar much smaller physically without significantly affecting their touch usability.

    You're very right, clarified! :)

    Take care,

    I will note that the idea of using gestures that originate in the bezel seems to be an evolution of the Palm(now owned by HP) gesture area on the Palm Pre and the other WebOS based smartphones. Yes, the tablet lets you use any bezel, but as I said, this is an evolution of the concept that Palm implemented with the gesture area.

    Since the HP Touchpad will not have a dedicated gesture area, it will be interesting to see how things play out going forward in the tablet space.

    But do the gestures really extend into the bezel area, or do they really just start at the first pixel your finger encounters when swiping from beyond the edge of the screen? I think it's the latter. Swiping from the bezel just insures that your finger will be detected hitting that first pixel in the screen at the edge, which tells the OS that it's a special "bezel" gesture.

    Maybe I'm wrong, but it makes sense to me that that's how it works, then thinking that the entire bezel is gesture enabled with sensors, though it's possible.

    Perhaps Anand, can help here.

    Mate, you wrote so many pages, but eschewed some of the most important questions.

    1) You discuss the screen, but make no mention of the technology - is it IPS? is it TN? As for the surface - is it polycarbonate? is it GorillaGlass?
    2) You discuss the USB, but make no mention of crucial use - does the Playbook have USB host capabilities? In other words, can you connect an external HDD to it (whether self-powered or externally powered) and read files from it?
    3) Since we mention USB and external storage, how about a peep about SD card support? Seriously... a review with nary a mention of additional/expandable storage?
    4) Why are you comparing it with the iPad and the Xoom, instead of comparing it with the only other real, usable device in its size class, namely the Galaxy Tab??? The Playbook is not for people who want large devices, who can get an iPad... Is it not clear that the size is one of the biggest factors at play here? You mention the Galaxy Tab exactly once, and make an intriguing statement that the Playbook is a bit larger... but when it comes to pictures, again you compare it with the Kindle (!??) and the iPad. Eh? the Kindle???

    I'm sorry to be harsh, but this is a rush job... just like the Playbook itself.

    Have you even read the review? It answers two of your three questions. The tablet doesn't have an SD card slot and it doesn't have an USB port either. Your fist question still stands, I'm also curious what panel technology its screen uses. Reply

    Incorrect. It does have a USB port, and the review specifically states this when discussing available charging options. The poster was asking whether its possible to use a male-male USB cable to connect mass storage to it. Reply

    of hearing everyone whine and complain about lack of matroska support. matroska has NO STANDING outside anime nuts who can't wrap their brains around a second file to contain subtitles. matroska is a tiny speck with no corporate backing, no manufacturer is going to dedicate development time or die space to support it.

    Actually it has pretty good manufacturer standing now, it's supported by Sonic Solutions/divx, ArcSoft, CoreCodec and all the serious chipset manufacturers of media player chipsets and STB solutions. As well as support on BD-players and televisions coming along. Nero also has support for it btw. Even boxes like the Roku now supports local playback and MKV. (Roku XDS with USB) Also there is no die space needed it's just a container. Software is all that's needed. Nokia also added MKV support in Symbian^3. Reply

    "As you'll see in our video tests, the PlayBook is the first ARM based tablet we've used that can decode a 1080p H.264 High Profile video stream."

    I believe the Hard Kernel ODROID-A was the first on the market (though in limited availability), as it's using the Samsung Exynos 4210 SOC. Would be great to see a test of that, to see how well the Exynos drives a tablet. I have high hopes for it.
