Samsung warns users not to charge a wet Galaxy S7
Getting your new Galaxy S7 or Galaxy S7 edge wet is perfectly acceptable, but be sure it’s completely dry before topping up its battery.
Samsung is warning users that charging with a cable while the port is still wet can cause damage to their shiny new smartphone.
“If you charge the device while the multipurpose jack is wet, the device may be damaged,” reads the Galaxy S7 user manual. “Thoroughly dry the multipurpose jack before charging the device.”
Given that water conducts electricity, and can therefore create unintended connections between different pins inside your charging cable, it makes sense that you shouldn’t plug it into wet ports. But it’s something you might not think about when using your new phone.
Even when the outside of your handset is dry, droplets of water can still linger inside ports where your towel cannot reach. It’s a good idea to blow these out, or wait some time before plugging a cable into them, then.
But although you can’t charge a wet phone by cable, it is possible to use wireless charging. In the video below, you can see the Galaxy S7 edge charging wirelessly while sat in a bag of water.
