Can You Really Take Your Phone Swimming?
It’s a question that comes up constantly in wild swimming communities: can you take your smartphone into the water with you? Whether you want to capture that magical misty morning dip, track your swim route, or simply keep your device close by on the riverbank, the relationship between smartphones and water is one that deserves a proper look.
Modern smartphones — iPhones in particular — carry impressive-sounding water resistance ratings. But what do those ratings actually mean in practice, and should wild swimmers trust them? The short answer is: with caution, and with a solid understanding of the limitations involved.
Understanding IP Ratings: What They Actually Mean
Most flagship smartphones carry an IP67 or IP68 rating. These are Ingress Protection ratings, and they tell you how well a device resists dust and water under controlled laboratory conditions. Here’s what the numbers break down to:
- IP67 — can withstand submersion in up to 1 metre of fresh water for 30 minutes
- IP68 — can withstand submersion in up to 6 metres of fresh water for 30 minutes (varies by manufacturer)
Those figures sound reassuring. But there are some critical caveats that every wild swimmer should be aware of before confidently plunging their device into a lake or river.
Laboratory Conditions vs. Real-World Wild Swimming
IP ratings are tested in still, fresh water at controlled temperatures. Wild swimming environments are anything but controlled. Rivers have currents that increase water pressure against your device. Open water is often cold — sometimes very cold — and temperature extremes can affect the integrity of seals over time. Salt water, which some open-water swimmers encounter at coastal locations, is far more corrosive than fresh water and can degrade seals and ports much more quickly.
There’s also the matter of wear and tear. A brand-new phone straight out of the box has pristine seals. A phone that’s been dropped, knocked about in a kit bag, or simply used for a year or two may have compromised seals without any visible sign of damage. Manufacturers themselves often state that water resistance can diminish over time — and many do not cover water damage under warranty as a result.
Practical Tips for Swimmers Who Want to Bring Their Phones
If you’re determined to keep your smartphone close during a wild swim — and there are perfectly good reasons to do so, from safety to photography — here’s how to do it sensibly:
- Invest in a proper waterproof pouch. A dedicated waterproof phone case designed for water sports offers an extra layer of protection beyond the phone’s built-in resistance. Look for cases with a tested depth and duration rating suitable for swimming.
- Keep the phone on the bank where possible. If you’re swimming with a group, consider leaving your device with your kit rather than taking it into the water. Designate someone to stay dry and hold phones for safety contact purposes.
- Avoid charging ports getting wet. Even on water-resistant devices, charging while the port is damp is a recipe for damage. Always dry your phone thoroughly before plugging anything in.
- Don’t test the limits repeatedly. Just because your phone survived one swim doesn’t mean the seals are good for dozens more. Treat each exposure as a risk, not a guarantee.
- Consider a dedicated action camera. If photography is your main aim, a purpose-built waterproof camera or action cam is far better suited to aquatic environments than any smartphone.
Your Safety Kit Shouldn’t Stop at Your Phone
There’s a broader point here about preparedness. Wild swimmers rightly think about what kit they bring — tow floats, dry robes, warm layers, emergency contacts. Your phone is one part of that safety picture, but it shouldn’t be the only one.
One area that’s often overlooked is knowing the quality of the water you’re swimming in. Rivers, lakes, and coastal spots can carry bacteria, agricultural run-off, and other contaminants that pose genuine health risks — particularly after heavy rainfall or in areas with nearby livestock. Checking whether a spot is safe isn’t just about avoiding an unpleasant experience; in some cases, it’s genuinely important for your health.
At Wild Swimming Tests, we supply easy-to-use water quality test kits designed specifically for wild swimmers. Whether you’re a regular at a favourite local spot or exploring somewhere new, testing the water before you swim gives you real information to make an informed choice — not just a rough guess based on how clear it looks.
Swim Smart, Swim Informed
Wild swimming is one of life’s genuine joys — the cold shock, the connection with nature, the community of like-minded people who understand why you’d choose a muddy riverbank over a heated pool. Protecting that experience means being thoughtful about every aspect of your safety, from the kit you bring to the water you swim in.
So by all means, take sensible precautions with your phone. But don’t forget the environment itself. Browse our range of water quality test kits at wildswimmingtests.co.uk/shop and make water quality testing a regular part of your wild swimming routine. Your health is worth it.
