Apple iPhone 15 and Asus Zenfone 12 Ultra tie on the OH Rank at a score of 61. Apple iPhone 15 wins on Screen and Video; Asus Zenfone 12 Ultra wins on Performance and Battery. Asus Zenfone 12 Ultra is 5.4mm wider than Apple iPhone 15. Asus Zenfone 12 Ultra is the more recent release, from Feb 2025.
EDITORIAL: iPhone 15 is an incremental update of the 14. While A16 Bionic (4nm) chip brings big performance improvements, screen got much brighter, USB-C Port got Video Out tech and the main camera went from 12 to 48MP, the ultrawide and selfie are the same, battery gained negligible 70mAh in capacity and worse of all: the 60Hz refresh rate remains.
EDITORIAL: This powerful phone features the top Qualcomm chip with excellent performance tuning - something Asus has been known for. Despite looking bland, Zenfone 12 Ultra is a great gaming phone that even includes a headphone jack. Battery life and charging are above average but will not get you a 24 hour battery life I use as a cut off point between "average" and "great" battery endurance. Screen is plenty bright and HDR10+ compliant tho only 1080p. Camera is solid and the OS is beautifully optimized and infused with useful and many good AI tools. Most of them can be used without accessing the cloud - something to appreciate it you value privacy and speed.
Both phones here were scored by me, using the same ten categories, with no ads, sponsorships, or manufacturer relationships — this comparison is as objective and honest as it gets.
