Based on several days of testing, it looks like Apple made the right cost-cutting trade-offs with the XR, which starts selling Friday for about $750. The standard XS starts at about $1,000; its supersized cousin, the XS Max, goes for $100 more.

The XR falls between the XS and the Max in size. Its screen is about 7 percent larger than the XS and 12 percent smaller than the Max. But the XR is closer in width to larger Phones such as the Max and older Plus models, so anyone upgrading from an iPhone 7 or 8 will have to get used to a new grip.
