With a super bright display, svelte dimensions and pleasingly comfortable construction, the Nokia Lumia 2520 isn't a tablet that's designed to be confined within four walls, so it's a good thing that Nokia has fitted it with a leggy 8000mAh battery.
Nokia claims that the battery will last for 25 days on a single charge, a test we didn't quite have time to verify. However, in general use (browsing the internet, playing some videos and undertaking some light gaming with the screen set to maximum brightness), the 2520 lasted an admirable 10.5 hours.
You don't have to wait long for it to charge either. Having to use Nokia's proprietary charger is something of a pain, but it means that the Lumia 2520 can go from zero to 80% charge in just one hour. Considering its battery life, that's one impressive feat.
Once you've powered up and logged in, the tablet's Snapdragon 800 processor zips along without any discernible lag or hiccups. As with the Surface 2, its pre-installed Microsoft Office Home & Student 2013 RT apps load up on command within a few seconds, adding to the tablet's pick-up-and-go feel.
After firing up 3DMark for Windows RT, we were forced to use the most graphically demanding benchmark it offers, because the others were "too light for your device". We didn't get that message when running the same app on the Surface 2, so it appeared off the bat that the Lumia 2520 packs more power - but is it substantially more?
Running the Ice Storm Unlimited benchmark gave us a test score of 16,864, which comfortably beats the Surface 2's score of 13,151. That extra power should come in handy when playing more graphically powerful titles on the platform.
