Three years ago I bought last primary phone. It was flagship of HTC, One with codename m7. This was absolute top phone, better than Samsung, better than iPhone. But it is past, the phone is get old, especially integrated battery is too old. Phone in normal day using (1h games, 2h internet, about 5 class with average length 5 minutes, push google services, company mail and facebook) was alive about 12h. So it come time to change?
