So I activated the phone, put in the sim card and restored. It was 5 pm when I did that. The phone was sitting at 60% of battery. For one hour I was installing new stuff from the App Store, playing with the phone, had a 5 min Skype video call, and then it was sitting for three hours idle. After four hours of a very moderate use it went down to 20%. So 10% every hour. Very moderate use. Where is the promised "almost two days" battery life?
