These are the 12 most believable iPhone 8 rumors we've heard

A report from reliable KGI Securities analyst Ming-Chi Kuo predicted that Apple would release a "high-end" iPhone with a larger 5.8-inch screen, compared with the iPhone 7 Plus's 5.5-inch screen. Many are calling this premium phone "the iPhone 8."

More recent reports claim the iPhone 8 will have a smaller 5.1- or 5.2-inch curved screen that will wrap around the edges of the device. It sounds like a similar design concept as the Samsung Galaxy S7 Edge. To add more uncertainty to the mix, 9to5Mac says it'll have a 5.5-inch screen.

So, it seems certain that Apple will release a new high-end iPhone model with some radical design tweaks, but no one can decide what size screen it'll have.

IHS Markit analyst Wayne Lam told MacRumors in March that he anticipates "Apple will adopt a flat implementation of OLED design on their special iPhone model," which directly contradicted a previous report that said the high-end iPhone would feature a curved wraparound display. We're inclined to believe the flat-screen rumor.

This is probably the most popular rumor about the "special 10th anniversary" iPhone.

In February, GSMArena reported that Apple struck a huge deal to buy 60 million OLED displays from Samsung. One month prior, Apple analyst Ming-Chi Kuo claimed Apple would reportedly use a different technology for its Touch ID fingerprint reader, which is linked to the rumors that Apple's next iPhone will have an OLED display.

Previously, rumors from The Korea Herald suggested the high-end iPhone would have an AMOLED display, even though the other iPhones released in 2017 — like the iPhone 7S, and the successor to the 4-inch iPhone SE — are expected to have LCD displays, like past iPhone models.

OLED displays are superior to LCD displays in almost every way. They're more power efficient, produce better colors, better contrast, and better brightness.

Rumors that the iPhone 8 would have an all-display front surface emerged from John Gruber, the plugged-in Apple blogger and podcaster from Daring Fireball.

Gruber says he has heard insider scuttlebutt that the iPhone 8's front won't have any bezels or borders, and that it'll be one large display.

Ming-Chi Kuo from KGI Securities claims the iPhone 8's body will be made of glass. If so, it could have a similar aesthetic as the iPhone 4 and 4S, both of which had a glass back.

A report from the Japanese news site Nikkei says Apple is indeed ditching the metal back design for an all-glass back and metal frame.

In January 2017, the KGI Securities analyst Ming-Chi Kuo claimed Apple would use optical sensors for the Touch ID home button. According to Kuo, optical sensors will allow the Touch ID button to be hidden, as they can read fingerprints through thicker OLED panels than the current iPhone's capacitive Touch ID sensor, which needs to be exposed.

Many support Kuo's prediction, including John Gruber, who says the home button, which also houses the fingerprint sensor, will be embedded into the front glass panel to make it invisible.

Recently, the Chinese tech giant Xiaomi released new phones with the same technology that Apple described in a patent for alternative home buttons, which could give us an idea of how a future home button on the iPhone 8 could work.

A Barclays report summarized by MacRumors said the iPhone 8 will have wireless charging. In general, we know that Apple has looked into the technology because of a patent filed on September 9.

In addition, Sharp president Tai Jeng-Wu apparently mentioned to university students that the next iPhone will include wireless charging.

In February 2017, an Apple spokesperson told Business Insider that the company recently joined the Wireless Power Consortium, an industry group that develops a widely-used wireless charging standard. It's not a direct admission that that Apple will add wireless charging to its upcoming iPhones, but it's a pretty good hint that Apple is at least interested in expanding its wireless power technology beyond the Apple Watch.

This one is easy. Since the iPhone 7 doesn't have a headphone jack, we can expect future iPhones won't feature a headphone jack either.

Ming-Chi Kuo from KGI Securities believes the dual-lens camera will remain an exclusive feature for the larger iPhone models from 2017 onward.

Fast Company's Mark Sullivan expects the upcoming "special 10th-anniversary edition" of the iPhone to cost more than $1,000, which lines up with many of the rumors coming out of Apple's Asian supply chain. This seems to be the consensus across all reports, so if you plan on buying this phone, prepare your wallet accordingly.

Apple normally announces new iPhones at its annual iPhone event in September. But a recent report from KGI Securities analyst Ming-Chi Kuo claims that Apple is struggling to get its high-end OLED phone screens ready for the ultra-premium iPhone in time because there is "there is virtually no time to make changes to the 3D camera system" before a September launch.

As a result, Apple could potentially announce the iPhone 8 with the "S" models of the iPhone 7 in September, or it could both announce and release the premium iPhone model at a separate event later in the year.
