The Nokia Lumia 520 has a 1430 mAh battery to keep it going. That's a slight boost over the 1300 mAh battery found in the Nokia Lumia 620, but some way short of the 1950 mAh battery packed into the Huawei Ascend W1.
The slight bump in battery size equated to a slight bump in performance over the Nokia Lumia 620, but it's an important improvement as while the Lumia 620 would sometimes struggle to make it through a day the Lumia 520 generally seemed fine - though you'd still normally need to charge it overnight.
In our patented battery test - running a 90 minute video from a fully charged handset with Wi-Fi on, social networks and emails set to push notifications and the screen turned up to full brightness, we saw the battery drop to 66% by the end of the test.
That's not brilliant performance, but when used in other ways - for example phone calls, playing music, sending texts etc the Nokia Lumia 520 performed a lot better and unless you're watching a lot of videos you should easily get a day's use out of it.
Nokia rates the Lumia 520 for up to 360 hours of standby time over 3G, 14.8 hours of talk time over 3G, 9.6 hours of talk time over 2G or 61 hours of music playback, which sounds fair, though it notably doesn't post figures on video time.
If the battery doesn't live up to your expectations there is a battery saver, which prevents apps from syncing in the background, plus you can also invest in a spare battery, since it's easily removable if you just pop the back off the phone.
However if you'd rather not do that then the Huawei Ascend W1 might be a better bet, as that is one of the few Windows Phone 8 handsets to actually sport good battery life.
The Nokia Lumia 520 has a handful of different connectivity options, including dual-band Wi-Fi 802.11 a/b/g/n, HSDPA at 21.1 Mbps and HSUPA at 5.76 Mbps. It has also got Bluetooth 3.0 and GPS, but it lacks NFC or a compass - both of which are included in the slightly pricier Nokia Lumia 620.
Configuring these connections or turning them on and off is pretty straightforward, as there are clearly labelled menus in the settings screen to sort them all out. Unfortunately digging into the settings screen is the only way to manage them, which is a bit of an annoyance as a shortcut would really come in handy.
Getting content on and off the Nokia Lumia 520 is totally painless, you just plug it into a computer using the included micro USB to USB cable, wait a few seconds for your computer to pick it up, then you can look through the handset's folders and simply drag and drop things on and off it.
There's also a micro SD card slot hidden beneath the back cover, which is all but essential for bulking up the storage from the 8GB that it ships with. Using a micro SD card additionally gives you an extra way to get content on and off the phone, as you can load it up with things before putting it in.
