The Google Pixel 10a features an IP68 dust- and water-resistant rating, matching the rest of the Pixel 10 series including the Pixel 10, Pixel 10 Pro, and Pixel 10 Pro XL. This rating means the device can withstand submersion in up to 2 meters of freshwater for 30 minutes, making it suitable for poolside use, accidental toilet drops, or quick underwater photos. However, the phone isn't completely sealed and requires caution with saltwater, extreme temperatures, and extended water exposure.

With an IP68 rating, the Pixel 10a is dust-tight, allowing comfortable use in sandy or dusty environments without damaging internal components. Users should still wipe down the device regularly and avoid large particles that could scratch the screen. While the phone can handle water exposure, it's recommended to dry it immediately after getting wet and consider a waterproof case for extended aquatic use. The water-resistant rating may degrade over time, though this won't be an immediate concern for new devices.

The Pixel 10a's IP68 rating is particularly impressive for an entry-level device in the Pixel lineup. While not the highest possible rating—phones like the OnePlus 15 achieve IP68 and IP69/IP69K for extreme durability—the Pixel 10a's water resistance puts it ahead of many budget phones that often lack robust protection. Combined with seven years of software updates, this durability feature adds significant value to Google's affordable smartphone option.
