Apple and Samsung will reportedly be neck-to-neck with their upcoming flagship smartphones. The next installment in the iPhone series and the next installment in the Galaxy S series are expected to feature an IP68 water resistance rating.

The Ingress Protection 68 rating or IP68 is the highest certification for the smartphone industry. Reports say that the iPhone 8 already managed to nab the rating. With the latest feature, iPhone's upcoming device will be more water-resistant than the last.

"Apple's iPhone 8 will feature the IP68 rating protection as part of drastic upgrades marking the 10th anniversary of the iPhone this year," a source tells The Investor.

Currently, Samsung is in the lead when it comes to water resistance features. Its Samsung S7 already holds an IP68 rating, which suggests that the device may be submerged in 1.5 meters of water for 30 minutes. Apple's iPhone 7, on the other hand, only has an IP67 dust and water resistance rating, which enables the device to be submerged in 1 meter of water for 30 minutes.

In terms of design, the iPhone 8 will reportedly feature a new design, one with an all-glass look, which closely resembles the iPhone 4 and iPhone 4s feature. Apple will be moving away from aluminum materials; instead, it will be using stainless steel. The design, however, will be an upgraded version of the iPhone 4.

From billet milling, which involves cutting the chassis from aluminum, Apple will now be utilizing a process called metal forging. The procedure involves squeezing a metal alloy into the mold, which consequently creates a stronger metal.

With the rumored new glass design, sources say that it won't come as a surprise if Apple's iPhone 8 will offer wireless charging.

Apple has yet to confirm the latest reports; hence, tech junkies should treat the latest claims as speculation until proven otherwise.
