Motorola is set to have five phone ranges on shelves before the end of 2017 according to a recent leak of a company presentation slide. We've already seen the Moto G5 and G5 Plus, as well as the Moto Z2 Play and Moto Z2 Force, but there looks to be a return for the Moto X too.

The Moto X took a step aside in 2016 to make way for the Moto Z flagships, but now it seems Motorola wants to bring it back as a sort of sub-flagship device. The last incarnation of the Moto X we saw was in 2015 with the Moto X Force, the Moto X Play and Moto X Style. In 2017 however, Motorola looks set to release just one Moto X model, which could combine the best of both the Play and Style.

A tweet from usually reliable tipster Evan Blass suggests the new Moto X will be called the X4, so we'll be using that for the purposes of this feature. Here is everything we know so far about what we can expect to see from the Moto X4 and when it will be released.

  • IFA press conference on 31 August could be potential launch date
  • Late 2017 rumoured for release making IFA likely 

Motorola held an event on 25 July in New York but it was the Moto Z2 Force that graced us with its presence rather than the new Moto X4. That leaves the path clear for IFA. 

Motorola has announced its press conference at IFA will take place on 31 August, the same day LG is expected to show off its LG V30 flagship. It is widely expected the Moto X4 will be announced at the IFA press conference.

According to VentureBeat's Evan Blass, the Moto X4 will release sometime in late 2017 in time for Black Friday, which takes place at the end of November, the day after Thanksgiving, which ties in with an IFA announcement.

  • Aluminium body
  • IP68 waterproofing
  • Dual-lens rear camera in circular housing suggested

Although leaked images and renders of the Motorola Moto X4 aren't as plentiful as the likes of the Samsung Galaxy Note 8, we do have a few things to go on. There is a small image of the device from the company's presentation slide showing all of Motorola's phones for 2017, a video of a similar slide and a larger and clearer image has also recently surfaced from notorious leakster Evan Blass.

The images show an all-metal build, which considering the G5's metal construction, is no real surprise. The Moto X4 is expected to be a sub-flagship phone so while it won't be gunning for the likes of the Galaxy S8 and LG G6, it should sit above the G5 and G5 Plus in Motorola's portfolio.

Based on the leaks, there are slim bezels either side of the screen and larger ones top and bottom, while the image leaked by Blass shows a physical home button on the front, which will no doubt incorporate a fingerprint sensor. The image from Blass also shows the signature "M" on the rear, as many Moto fans will now expect, along with a raised circular camera housing that features dual-lenses and a flash beneath.

Google Plus user Jerry Yin also posted some photos purporting to be the Moto X4 on his profile. The photos confirm the metal build and home button and also show the rear camera with two lenses, supporting the leak from Blass.

The Moto X4 is also claimed to have an IP68 rating, keeping up with the likes of the Samsung Galaxy S8 and Sony Xperia XZ Premium. This will mean it can be submerged up to 1.5-metres for 30 minutes. Don't hold your breath for this though as even the tough Z2 Force doesn't offer an IP rating, just weather resistance.

  • 5.2-inch display
  • Full HD resolution reported, 424ppi
  • Button and fingerprint sensor beneath display 

According to the leaked Motorola presentation slide show, the Moto X4 will have a 5.2-inch Full HD display with 3D Glass. The size and resolution has been supported by a leak from Evan Blass and given the X4 isn't set to be flagship device, the leaks are plausible. If true, the Moto X4 will offer a pixel density of 424ppi.

It's not entirely clear exactly what 3D Glass is, but we suspect it will give the Moto X4 curved glass edges to the screen, similar to what the Apple iPhone 7 does, giving a seamless finish between display and the edge of the device.

Jerry Yin's photos show the Moto X4 with onscreen buttons, as we've seen on previous Motorola phones and many other Android devices. As we mentioned previously, the leak from Blass also shows a button beneath the display, something we have also seen on previous Moto handsets.

  • Dual-rear camera with LED flash
  • 12MP and 8MP sensors on back suggested
  • 16MP front snapper reported

Evan Blass and Jerry Yin's photos both show the Moto X4 with a dual camera system, with both lenses inside a circular module on the rear like the recently launched Moto Z2 Force.

Based on the two leaks, the dual-lens camera also appears to come complete with an LED flash, also built into the circular camera module, though the flash appears to be larger and more prominent on Yin's leaks compared to Blass's.

While Yin's leak didn't make it clear what resolutions the cameras will be, Blass from Venture Beat claims the Moto X4 will come with an 8-megapixel sensor and a 12-megapixel sensor on the rear, while the front-facing camera is said to be 16-megapixels. We do not yet know whether Motorola will opt for the same RGB and Monochrome sensor combo like it did with the Z2 Force.

The presentation slide leak also mentioned something called SmartCam, which we suspect will be some sort of software integration to provide better quality photos, but we may have to wait until Motorola's official unveiling to find out for sure.

  • Qualcomm Snapdragon 630 or Snapdragon 660
  • 3GB or 4GB RAM and 32GB or 64GB storage suggested
  • 3000mAh or 3800mAh battery reported

Jerry Yin's leaked images provided us with a screen detailing some of the Moto X4's proposed internal specs, including 3GB of RAM and 32GB of onboard storage. A leak in China, which was translated by a Reddit user, has claimed the Moto X4 will have 4GB of RAM and 64GB of storage however, as has Evan Blass, suggesting there could be two variants or that Yin's leak is wrong.

In terms of the processor, the Chinese leak suggests the Qualcomm Snapdragon 660 will be under the hood, though Evan Blass claims it will be the Snapdragon 630 chip. We weren't expecting a Snapdragon 835 that's for sure, so either the 630 or 660 are plausible options.

The Moto X4 is also said to have a relatively large battery at 3800mAh, with Quick Charge technology, though the exact version has yet to be specified. Venture Beat contradicts this capacity however, claiming the Moto X4 will in fact have a 3000mAh battery and although it doesn't mention anything about Quick Charge technology, we'd be surprised not to see it. 

Apparently the fingerprint sensor embedded in the home button that we mentioned previously will not only be capable of unlocking the phone, but it has also been suggested that it will also recognise gestures to navigate around the screen and menus and support Google's pay-as-you-go Fi MVNO service.

  • Likely to be Android Nougat
  • Minimal bloatware expected

Although we have yet to see any specific leaks surrounding the Motorola Moto X4's software, we're expecting a close to pure Android experience with a couple of Motorola apps introduced over the top.

Motorola traditionally doesn't use as much bloatware as the likes of LG or Samsung, meaning it tends to get quicker updates to the latest Android software builds. We'd expect the Moto X4 to launch on Android Nougat but a relatively speedy update to Android O when it is released wouldn't be too surprising.

While we do have some leaks and rumours to go on, there's still a lot about the Moto X4 that we're simply speculating on for now. We still don't know when we can expect to see it officially announced for instance, though end of August is seeming likely.

Based on the rumours we have seen, the Moto X4 should be a decent sub-flagship device. We will keep you posted on any new rumours and leaks that appear so keep checking back for the latest.
