What is meant by IP rating of waterproof mobile phones?
Most of the big brands and few other manufactures have waterproof smartphones. These smartphones refer these mobile smartphones as IP rated phones. IP rating is the international standard that defines the degrees of protection devices provide against liquid, dust and solid objects.
What is meant by IP rating?
Those letters ‘IP’ refer to “ingress protection”, which in layman’s terms means how easily dust and water can intrude on the internals of your device.
The IP part of the term won’t change, so it’s the numbers you’ll actually need to look at to work out how resilient your device is designed to be.
The first number in the sequence refers to the solids protection of the device. That means it’ll tell you how likely it is for dust to get into the device and whether for example it’s likely to be a problem if you take your device to the beach and drop it in the sand.
Devices including the iPhone X, iPhone 8, Samsung Galaxy S8, Sony Xperia XZ1 and even the Apple Watch 3 all make the claim of being water resistant, but they don’t all have the same IP rating.
You’ll typically see numbers such as IP67 when referring to the iPhone X or the iPhone 8, while the number IP68 is used when referring to the Samsung Galaxy S8, Galaxy Note 8 or Sony Xperia XZ Premium.
Mostly you’ll only see the number five or six displayed here. The number five means the “ingress of dust is not entirely prevented, but it must not enter in sufficient quantity to interfere with the satisfactory operation of the equipment; complete protection against contact.”
However, if it’s a six, it’ll be more protective as the definition reads “no ingress of dust”, and it offers complete protection.
Sometimes you’ll also see a rating like IPX8, which is where the company doesn’t reveal the number for its products dust protection so instead replaces it with an ‘X’.
Which number in IP rating refers to waterproof?
The second number in your IP rating refers to how waterproof the device is, and it’s a little more complicated than the first number.
Almost all mobile devices have an IP rating with a number of at least three or four, which protects against splashing or spraying water and ensures your device doesn’t get instantly ruined by the rain when you’re using it.
The numbers you’ll be interested in start at five. That is protection against “water projected by a nozzle (6.3mm) against enclosure from any direction.” If your IP rating is number six, it’ll protect against “water projected in powerful jets (12.5mm nozzle) against the enclosure from any direction.”
What devices are water proof in IP rating?
Waterproof devices are those with numbers from seven onward, but they still vary. The number seven means “ingress of water in harmful quantity shall not be possible when the enclosure is immersed in water under defined conditions of pressure and time (up to 1 m of submersion).”
A rating including an eight for the second number will refer to devices that can handle submersion beyond 1 meter, but no device is ever completely waterproof.
The official definition of the top water resistant number (nine) is, “the equipment is suitable for continuous immersion in water under conditions which shall be specified by the manufacturer. Normally, this will mean that the equipment is hermetically sealed.
However, with certain types of equipment, it can mean that water can enter but only in such a manner that it produces no harmful effects.”
Are water proof smartphones 100% water proof
No phone is 100% waterproof. It’s always possible that you’ll get a bit of water seeping into your device if you submerge it at very deep depths or leave it there for a long time. But if you have a high IP rating it’s likely you’ll be able to use your device in the bath or near a swimming pool without having to worry.
IP67 devices include the iPhone X, Huawei Mate 10 Pro, Google Pixel 2 and Pixel XL 2, HTC U11 and the iPhone 8, as well as the iPhone 7.
IP68 certified devices include the likes of the Samsung Galaxy Note 8, Galaxy S8, Galaxy S8 Plus, LG V30, LG G6, Sony Xperia XZ1, Sony Xperia XZ Premium and the Samsung Galaxy S7 range.
Points to remember
- IP ratings are based on immersion in clean water in laboratory conditions.
- They don’t cover hot water, or soap, or chlorine, or salt water, or anything else you might find polluting your water supply.
- The addition of those elements can entirely void any waterproofing measures on a given device, and if they’re detected as having been present if you make a warranty claim on a device that’s failed while immersed, the vendor may be able to knock back your warranty claim.
What if you dropped your mobile in water?
If by accident or otherwise you have dropped your mobile in water, then the first step is to power down your phone if it’s not already off. If you have a phone with a removable battery, pull it out as fast as you can to be sure.
The next step is to allow time for as much water to exit the phone body as possible before trying to use it again. While there are commercially available products that attract water into a sleeve or pocket around a phone, the old low-tech way is to drop it into a small bag of rice and leave it for a period of at least 48 hours before trying to switch the phone back on. As noted, there are no guarantees, but given that, it’s worth the price of a small bag of rice to try.
If you don’t have a water proof mobile, you can go for a waterproof phone cases. There are a number of available cases for popular models – predominantly iPhones or devices in the Samsung Galaxy family . These offer both water and drop resistance features. These typically involve heavily sealing your phone within the confines of a rigid case that locks down tight around every possible entry point for water.
So if you’re going to regularly have your phone in harsh environments including water-heavy places, you can have water proof covers for your phone. Although again their warranties will only cover you for the cost of the case in the event of a failure, rather than the whole phone itself in most cases.
Most of these cases also make it harder to use some features such as 3.5mm headphone jacks or fingerprint sensors depending on the way that the case has been constructed. So check them before you opt to buy.
