I am about to buy a new iPhone, and I am in doubt which one should I buy. I currently use an iPhone 5. I use it for checking and answering e-mails, web surfing, reading documents, exchanging messages, listening to music, playing games, reading books, and so on. Heavy usage. And I like to use it one-handed. As I use it a lot during the day, I keep it on a Mophie Juice Pack Plus, and I make serious use of it. I need the extra battery to get my iPhone 5 through the day, and I usually charge it as well. So, here is my doubt. Should I buy the iPhone 6 or the 6 Plus? I like the iPhone 6 better, because I can use it with just one hand. Very comfortable to use indeed. However, the screen of the iPhone 6 Plus is great, and battery life is supposed to be much better. I would buy the iPhone 6 for its size, but will the battery be enough? Will I need a Mophie case, and will that make the iPhone 6 the size of a 6 Plus but without the extra screen? I would prefer the smaller screen as it would be more comfortable to handle. I once had a Galaxy S4 and I hated it, as it was very uncomfortable to handle and to use. What do you suggest?
