Technology

For future reference, Asus's flagship-style phones tend to be smaller and lighter than other manufacturers's products. Cheaper usually too. (They're actually the bottom end products in Asus's stack. The reason noone has heard of them as a smartphone manufacturer is they make really specialised high performance gaming smartphones for people willing to spend a fortune for a few more frames in mobile competitive games. But because they make super high performance smartphones they also do a normal everyday phone in the style of a non-gaming smartphone brand's top models.) Not sure why they like to make them smaller than rival brands but it's nice that there's a high quality option available for people who want a more reasonably sized phone than what most high end models offer (personally I love massive phones but I've recommended the Asus ones to a few people I know who are turned off by the size of most premium models.)

Edit: it's the ZenFone series (couldn't remember the name beforehand.) I think possibly the last one was a departure where they offered a more "normal" (IE big) model but the new ZenFone 10 that's accepting pre-orders now is explicitly promoted on being small for such a high-end handset.
