Business card-sized Japanese phone
Its simple design argues that, sometimes, a phone can just be a phone. The KY-O1L has a 2.8-inch ePaper display—the same technology found in a some e-readers.
The handset measures at just 91mm×55mm×5.3mm and weighs 47g. The Palm phone measures at 96.6mm×50.6mm×7.4mm, and a credit card is typically only 0.76mm thick. For comparison, the iPhone XS and XS Max are 143.6mm×70.9mm×7.7mm and 157.5mm×77.4mm×7.7mm, respectively.
Japanese carrier NTT Docomo, which will release the KY-O1L, claims it is the world’s thinnest smartphone. “Smartphone” feels like a little bit of a stretch. The KY-O1L doesn’t run iOS or Android, and it has no app store.
It also has no camera. It has built-in apps, though, including a Web browser, a calculator, and a calendar—so sure, it’s technically a smartphone.
It has a 380mAh battery, which sounds abysmal, but the ePaper display should not use very much power, so we wouldn’t be surprised if its battery life is just fine regardless.
The KY-O1L will launch in Japan on NTT Docomo in late November for ¥32,000, or roughly $285 at current exchange rates. Frankly, that’s a bit pricey for what’s included; the Palm phone will have significantly more features for $350.
