The big-screen phone segment in 2026 is defined by displays of 6.7 inches and larger, with flagships now pushing to 6.9 inches while maintaining surprisingly manageable dimensions. The Samsung Galaxy S26 Ultra leads the pack with its 6.9-inch QHD+ Dynamic AMOLED 2X display peaking at 2,600 nits, slimmer ergonomics than its predecessor, and the Snapdragon 8 Elite Gen 5 processor. The iPhone 17 Pro Max matches it at 6.9 inches with an industry-leading 3,000-nit peak brightness and the best battery life ever in an iPhone at 5,088 mAh. [src1, src2]
For users who want large screens without flagship pricing, the OnePlus 15 stands out with its 6.78-inch AMOLED display and record-setting 7,300 mAh battery -- the first phone to exceed 24 hours in Tom's Guide's battery test. The Samsung Galaxy S25 FE delivers 6.7 inches of AMOLED at roughly half the Ultra's price, while the Samsung Galaxy A56 brings the same screen size to the sub-$450 segment. [src1, src3, src7]
