Alright, from the looks of it, there seems to be a noticeable improvement in battery life on the very first day of using the 520 with Black update. On am average, I get about 10 hrs in normal to heavy usage. Today its 11 hrs and another 21 % remaining! Sounds good! But I may have just been lucky. Will keep a check on this and update. Am loving not having to press the back key constantly for going to main menu...a long press of the back key, press the 'X' on the top of the app...done! Also, the driving mode feature is a handy tool. And did I say I am loving the Nokia Camera app...awesome manual controls over various aspects of photography. All in all, this update has made the 'modest' Lumia 520 even more value for money than ever!
