Battery Life

The battery life is one of the areas that I was concerned about when I purchased the Stream 7. It sports an 11.1Wh battery, which is smaller than the battery in some smartphones like the Galaxy Note 4 and the Nexus 6. However, the battery life of a device does not depend entirely on the battery capacity. The power draw of the display, CPU, RAM, and other components will be what determines how fast the battery is drained. To evaluate the battery life of the HP Stream 7, I've run it through our web battery life test and our video playback battery test. I've also run our video test on the iPad Air 2 as it was unable to be tested in time for its original review. This provides a point of comparison to another modern tablet, albeit a much more expensive one.

Web Browsing Battery Life (WiFi)

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

Unfortunately, there's just no getting around the fact that the Stream 7 has a really small battery for a 7" tablet. It gets the lowest score in both our web browsing and video playback tests. Both results are significantly less than the "up to 8 hours" that HP rates the battery for. It's likely that enabling Intel's DPST will improve these results, but all that really means is that dimming the display below our 200nits standard will improve battery life.

Charge Time

With a smaller battery, one can at least hope that the time to charge it will be shorter than other devices. However, this will be influenced by the charger that the company supplies with the device. In this case, HP has included a 10W charging block with the Stream 7. What's funny is that it's not an HP branded charger; it's a Chicony Electronics charger with an HP sticker on the front. 

Charge Time

Thankfully, the Stream 7 doesn't take very long to charge after its short battery life has been used up. It's not quite as fast as the Galaxy Note 4 or Nexus 6, both of which ship with higher wattage chargers, but it's still much quicker than the other tablets on our list as a result of its smaller battery. One thing to note about charging the Stream 7 is that I was unable to get it to charge off of any computer USB ports. This was surprising, because my computer has 1.5A USB 2 ports that are able to charge even the iPad 3 and its massive battery.

    With a single gig of ram it is far from very exciting or usable... I've been looking for a small factor x86 tablet with 4 gigs of ram, but all devices are crippled to 2 gigs of ram max.

    Have you tried one? It works OK with 1GB RAM. You can browse the web, including heavy sites, just fine. It runs Office quite adeptly. All the standard desktop stuff works great, as does (obviously) metro apps.

    Obviously it would be much better with 2GB. No doubt. But it _is_ usable with 1.

    I can do that on my android phone, the benefits of having x86 device is running full desktop applications which are not available for android, which do not run at all well with a single gigabyte eof ram.

    That's why i'd prefer a device that has not been crippled to only serve for basic tasks by having little ram, which is not expensive at all.

    Of course, running a desktop application on a tablet is almost as bad as trying to use Teamviewer to control a Windows device from an Android tablet. Windows desktop applications, especially legacy apps that were not built with any thought for a touch interface, are just not a great experience.

    I don't care about the user experience, my primary intent is to run a full C++ compiler on the device. It is the kind of things you just run without interacting with it at all.

    I've been using a Toshiba encore 8 for about 10 months now, after using previous android tablets. App selection does not bother me.

    Web browser works
    Email works
    youtube works
    twitter works
    Amazon instant video works (granted need to use desktop version of IE) this is one app i would like
    Netflix works
    I got a full version of office 2013 so, I can edit documents when out on the road (although would never want to spend hours working on a 8" screen)

    Bottom line it does everything I need at a fraction of the cost of other tablets and it comes with office.

    One thing the reviewer should note, on a desktop/laptop without a touch screen Windows 8.1 automatically boots to desktop so you barely see the start screen, you don't need any 3rd party apps to do that (also right clicking on the start button, gives you lots of options that used to be in the start menu)

    Well, the included Office 365 is built with touch in mind, I have already created few tables for my work using touch screen and finished the last 20% of work on my desktop. Btw, I prefer the desktop IE on my Linx 7 as well. To me it is very usable even for desktop apps.

    Then this device is clearly not for you. you're complaining that an super budget device doesn't have high end specs.

    Out of interest, what's the cheapest x86 tablet with 4gb of ram you've found?

    Why do people read reviews of products and take the time to moan about the fact that it's not what they need. Shop nfor something else.

    I got a refurbished i3 Dell Venue 11 for £215. It has 4GB of RAM and a real 128GB SSD. It's bigger than this, I'll grant you, but it's a lot of power for the money and on a larger screen - desktop apps are usable. The latest version of Photoshop CC with a stylus is amazing!

    These devices got generally favourable reviews but suffered from terrible bugs (it froze every 10 minutes or so out of the box!) until a series of firmware updates for almost every component of the device (a touch screen firmware I get, but firmware for the LCD itself to fix a panel self refresh issue?! I didn't even know that was possible...) and now it's great with amazing battery life too.

    Sadly, Linux currently has a bug which prevents the internal LCD from working with graphics acceleration, although I have got OS X booted on it. I'm missing a few Android apps right now, so hopefully the kernel bug will get fixed because I haven't found Bluestacks a very good experience. It has 64-bit UEFI and a CSM so in theory it should run anything...

    It's a bit odd going from a Nexus 7 with a 1920x1200 7" panel to this with a 10.8" 1920x1080 one. I guess high DPI windows tablets will eventual arrive but at least this panel has good contrast and seems relatively well calibrated.

    I can even play a bit of Portal 2 on it!

    You're wrong. They run just fine.

    That was the point of my post.
