Before you charge, make sure everything is totally dry first, as quickly as possible – but not using an oven or a hairdryer.
Pay most attention to the charging socket. Electricity and water need to be kept apart to keep both you and your device safe.
Some devices come with covers that help keep out water – please make sure you use them.
Don’t immerse your device intentionally, and keep it away from salty or chlorinated water, and drinks. Also remember that wear and tear can gradually reduce water resistance – take good care of your devices to maintain their resistance.
Get it dry as quickly as possible, ideally at room temperature without using an oven or a hairdryer - there’s lots of detailed advice on the web.
If you’re looking to buy the best dustproof and waterproof phone, you’ll need to check out the IP rating. It tells you how much water and dust your phone or device can withstand. It’s more precise than terms like ‘water-resistant’, but even devices with the same ratings can vary – check the individual specifications if you’re keen to know.
‘IP’ stands for or ‘ingress protection’. For devices, the first number tells you about the dust resistance. 5 means ‘dust protected’, so a bit of dust might get in but not enough to stop the device working. 6 means completely ‘dust tight’ – no dust will get in.
The second number is for liquids. Devices rated at 5 are protected against water spraying on them. Ratings of 7 mean the device is safe at between up to 15cm and up to 1 metre deep. A rating of 8 means the device is protected in more than 1 metre of liquid.
If there’s an X, such as IPX8, it means the device isn’t rated for that factor – so IPX8 would be tested for waterproofing but not dustproofing.
Some manufacturers provide more details, such as Sony. We’d recommend exploring manufacturers’ websites for more information.
