I switched some days ago from an iPhone 6 128 GB to an iPhone 6 Plus 64 GB and i think i fall in love with the 6 Plus. The battery life time is amazing. Before i had to charge every day, yes i'm a heavy user. Now with the 6 Plus the battery holds between 2-2,5 days with heavy usage. I wasn't sure about the size and the weight of the 6 Plus, but after 2 days I have already got used to. The iPhone 6 Plus is amazing smartphone and I'm very happy now that i switched, because of my big frustration of the iPhone 6 battery life time.
