On beach and island trips, so much happens on the water: boat trips, sandbank picnics, snorkelling off the reef. Phones and seawater don't mix, though. Here's the gear that protects them and the limits you should know.
What "IPX8" actually means
IP ratings come from the international standard IEC 60529. An IPX8 rating means protection against continuous immersion under conditions specified by the manufacturer. There's no universal depth or time; each maker sets them (IEC 60529 via NEMA). Always read the depth and duration on the product page before you trust it.
Your phone's own rating isn't a snorkelling licence
Modern phones carry IP68 ratings, but those come from controlled lab tests. Apple's support page says iPhone water resistance isn't permanent, and it advises against swimming or bathing with your iPhone, exposing it to pressurised or high-velocity water, or intentionally submerging it (Apple Support). Salt water, sand and sunscreen add more risk.

Waterproof phone pouch
Pros: cheap, light, lets you take photos at the surface. Cons: touchscreens can be unreliable underwater, and seals wear out over time. Tip: before every trip, seal a tissue inside and hold the pouch underwater in a sink. If the tissue comes out wet, don't use the pouch. Set a volume button as the shutter before you get in the water.
Roll-top dry bag
Pros: keeps everything dry on spray-soaked boat rides and wet beach landings. Cons: made for splashes and short dunks, not for wearing underwater. Tip: roll the top at least three times before clipping it shut.
Floating strap
Phones sink fast off a boat. A floating strap, or a pouch that floats, gives you a chance to grab it.
Weatherproof tech pouch
Peak Design describes its Tech Pouch as made from weatherproof recycled nylon. That's fine for spray and rain in a beach bag, but it isn't an immersion pouch.
FAQ
Can I scuba dive with a phone pouch?
Most pouches aren't designed for scuba depths. Check the maker's rated depth, and use a dedicated dive housing for diving.
Is IPX8 enough for snorkelling?
It can be, if the maker's specified depth and duration cover what you're doing. Read the product page.
Will salt water damage a water-resistant phone?
Apple advises against swimming with iPhones and against exposing them to liquids beyond fresh water. Rinse gear with fresh water after the beach.
What dry bag size should I get?
About 10L for a phone, wallet and power bank. Around 20L if you're adding a towel and a light layer.
Can I charge my power bank on the boat?
Keep it in a dry bag and in the shade. Heat and seawater are bad for lithium batteries.
Conclusion
For a typical beach or boat day, pack an IPX8 pouch for the water, a dry bag for the boat, and a floating strap, and test the pouch at home first. Leave serious underwater photography to proper housings.
