Bought 1 last 2 days to replace my Ativ S due to bigger screen size. Performance wise almost same but more application support for Nokia. Camera and screen i think Ativ S is better. Resolution same with Ativ S but because of the size the display not so sharp. Even compare with my Note 2 the screen color and resolution not very sharp, just on par if not better than my NEXUS 7 (1st model).

Overall satisfied with WP8 performance even app choice not so much compare to android but i got what i need in window store. OS Smoothness also very noticeable compare to android. Only regret is I should have bought 1520...

I think 1320 is value for money. Of coz 1520 spec is much better but i dont use camera all the time so its not really important to me...

I couldn't find the option on batt saver...can you please advice or upload screenshot here?

I guess it will never light up...
