The Asus ZenFone 9 is the only compact Android flagship with two major strengths: great performance and long battery life. It scores above the main competing models and has kept battery life several hours above rivals. The camera and screen are also two interesting advantages. The only problem, for now, remains the price positioning. It's quite high compared to rivals, around the same price as the Galaxy S22 compact. Here it depends on one's preference toward brands.
