Apple's iPhone's reliability rating is almost 3X that of its closest competitor. 1.5X, okay. 2X would get a wow from me. However, the iPhone being three times better than Samsung?
Well, it'll be interesting to see how FixYa's rating methodology came to this conclusion. Regardless, it's pretty safe to conclude the iPhone is very reliable and Apple's legendary quality persists under Tim Cook's reign.
However, I don't think it's something that Apple should brag about. Nor will they. First, word of mouth is probably good enough. Second, there is still a lot of room for improvement.
Battery life. Yup, that's our main concern. Come on, Apple. With iPhone 5S or 6, try for 4X better than anyone.
