iPhone 6 Plus comes with a 5.5-inch Retina HD Display. There are some great advantages of the bigger screens especially in case of the iPhone 6 Plus, as they behave more like a smaller iPad than a bigger iPhone, which can help in improving productivity, especially while using it in landscape mode.
Landscape mode on the iPhone 5s/5c/5 was hard to use, but thanks to the bigger screen, landscape mode on the 6 is great for writing emails editing documents, messaging and more!
Apps like Mail and Messages are easy to use via split screen mode. Now in the Mail app rather than going back and forth to the list view to check a new mail, you may now tap on the new mail in the list view to the left. If you wish to cancel the split screen mode see this.
Now you can get dditional keys such as cut, copy, paste, bold text, undo, exclamation mark, question mark etc while in landscape mode.
Watch 1080p Full HD videos on the iPhone 6 Plus in 1:1 mode. You can see everyting on its 1920×1080 resolution screen.
The Home screen orients in landscape mode similar to an iPad. This makes switching apps more convenient.
See more than one folder page in landscape mode. You can access 6 to 12 additional app icons in the folder view in the landscape mode.
