NEW YORK — Apple’s new and bigger iPhone 6 and iPhone 6 Plus are more durable than last year’s model and a leading Android phone, a study says.
The iPhone 6, whose screen is 4.7 inches, did the best in a variety of tests that measure how prone smartphones are to breaking in everyday accidents, according to SquareTrade, a company that provides extended protection plans.
The iPhone 6 Plus, whose screen is 5.5 inches, wasn’t far behind but lost points because it could slip out of a person’s hand because some users may have a hard time gripping its large but slim form, SquareTrade says.
The iPhone 5s, which measures 4 inches and came out last year, fared better than Samsung’s Galaxy S5, which is 5.1 inches. The Samsung phone got poor marks on several tests, including the slide test. The more a phone slides, the greater its chance of falling off a table.
Still, all four smartphones tested had a medium risk of breakage and had no drastic differences between them.
‘‘The phones are getting more and more durable,’’ said Ty Shay, chief marketing officer at SquareTrade. ‘‘Manufacturers are paying more attention.’’
SquareTrade examines the phones based on eight factors, including size, weight, grip, and quality of front and back panels. The company measured how far the phones slide when pushed across a table on their backs and how well they withstand drops from 4 feet and being dunked in water for 10 seconds.
SquareTrade said it uses robots to do the testing to ensure consistency and rates the phones on a 10-point durability scale, with 10 signifying the highest risk.
The iPhone 6 scored best at 4; the iPhone 6 Plus scored a 5; the iPhone 5s a 6; and the Samsung Galaxy S5 a 6.5.
The iPhone 6 and iPhone 6 Plus passed the slide test, but the iPhone 5s and Samsung Galaxy’s S5 got poor marks in that area.
The iPhone 6 Plus was the only one that did not fare as well when dropped 4 feet. The glass screen survived, but the case separated from the glass. All four phones did well in the water test.
Aside from larger screens, the new Apple iPhones 6 and 6 Plus promise faster performance and offer a wireless chip for making credit card payments at stores by holding the phone near the payment terminal.
The phones start at $199 with a two-year contact. The new iPhones initially were available this month in the United States, Australia, Canada, France, Germany, Hong Kong, Japan, Puerto Rico, Singapore, and the United Kingdom. Twenty more countries will get them, too.
