Thinnest Phones: 10 Top Picks for Thin Smartphones

Want a new phone but not interested in a heavy, thick brick that doesn’t fit in your pocket or purse? Read on to learn about ten of our favorite thin phones to consider.

When searching for the thinnest smartphones, the top priority is a slim profile, but our criteria extend beyond measuring millimeters. To arrive at our list of the top thin mobile phones, we considered the following factors:

  • Performance: Beyond their slim profiles, these phones, whether an Apple iPhone or an Android device, deliver great performance. Equipped with powerful processors like the Snapdragon 8 Gen 3, they promise speed and efficiency.
  • Feature-Rich: These phones, ranging from the iPhone 15 Series to Samsung Galaxy models, don’t compromise on features despite being slim. Expect top-notch specs like high refresh rate screens, impressive rear camera setups, and fast charging capabilities.
  • Innovation: These phones represent the pinnacle of innovation in the smartphone industry. Features like water resistance, foldable phone designs, and cutting-edge specs like the high mAh batteries make them more than just the thinnest or lightest phones.
  • Battery Life: Some manufacturers use a smaller battery when designing a slim phone. Our list left out some of the thinnest phones in favor of one sporting a battery that won’t require constant charging. 
  • Availability: Some of the very thinnest phones, such as the Honor Magic V2 or the Vivo X5 Max, are only available in certain markets, like India or China. While we hope that may change one day, for now, all the phones on this list are available to buy in the U.S.
