I read battery life is great when the phone is not being used and can drain quickly when it is in use. I have found this to be very true. A lot of people saying the battery life is bad are both right and wrong. It depends how you use the phone. A frustration I had with my HTC one would be I could go a day in work having the phone out for maybe half an hour on a break and then come home with under 30% battery life. With my n5 I am getting home with 70%+. For me this is really great because when you are near a charger battery life is far less of an issue. I am gonna pick up a cheap qi charger and have it about the main living room at home.
