Nokia Lumia 620 - How's the battery ?

I really want to try out a Windows Phone 8 device on the cheap and also won't really look beyond Nokia devices (just the best ones in my opinion). So I'm stuck with the choice between a Lumia 520 and a Lumia 620. Both look like great devices for the price, but there's one thing I'm concerned about....battery life.

I previously owned a Lumia 710, which had possibly the worst battery life I've ever experienced on a phone. I'm more inclined towards getting the 620 as it just seems like a great device.

So I'd like to hear from Lumia 620 owners about how they think the battery life is, leave comments below.
