Four hours of screen on time will drain the battery of any device, especially with an AMOLED display.
I've had nothing but good luck with my Lumia 1020. With moderate to heavy use, I can get through a full day on 3G.
Hi Everyone,
Just wanted to introduce myself. Just switched over from Android (Nexus 5) and I'm loving my Lumia 1020.
Looking forward to being a part of this community.
