If you're tired of lugging a typical smartphone everywhere, Apple and Samsung have thin alternatives. A bit lighter, more comfortable to hold and undeniably good-looking, the iPhone Air and Galaxy S25 Edge are pushing the envelope of slim phone designs. They're also instrumental in paving the way for foldables like the Galaxy Z Fold 7 and the rumored iPhone Fold.
