Following the launch of the ZenFone AR a couple of months ago, Asus has announced a new Android phone and called it the ZenFone 4. That’s a name Asus has used in the past, which rather confuses things.
When is the ZenFone 4 release date?
There’s a second model the ZenFone 4 Max. The Max refers to a huge 5000mAh battery, not a larger screen. You can see the full specs of both phones below.
How much does the Asus ZenFone 4 cost?
The ZenFone 4 costs £449.99. The big-battery ZenFone 4 Max costs £249.99 from John Lewis.

ZenFone 4
It’s clear that the ZenFone 4 bears more than a passing resemblance to the 5.5in iPhone, and it even shares the same 1920×1080 resolution.
Like the iPhone 7 Plus and 8 Plus – and many new phones – there’s a dual-camera setup at the rear.
Unlike the majority, though, Asus has gone for a 12Mp main camera and a secondary 8Mp sensor with a wide-angle lens.
The former uses Sony’s flagship IMX362 sensor and it focuses using dual pixel phase-detection autofocus (PDAF). Asus says at 0.03 seconds, it’s the world’s fastest.
The camera also benefits from optical stabilisation on four axis which allows long(ish) exposures of 1/4 sec.
and image processing is handled by a Qualcomm Spectra 160 chip.
The wide-angle camera isn’t ultra-wide like LG’s recent phones, but it has a 120° field of view which lets you fit a fair bit more in the frame without introducing too much distortion.
There’s plenty of flagship-level components including Cat 12 LTE, Bluetooth 5, 802.11ac Wi-Fi, and you get extras missing from the ‘Max’ version such as USB-C, hi-res audio, stereo speakers, a fingerprint sensor and NFC.
Asus keeps the price down by sticking with a full HD screen rather than quad HD, and there’s no waterproofing.
ZenFone 4 Max
Similar in name and design, but very different inside, the Max is intended to offer huge battery life for those on a tighter budget that don’t care so much about having the best cameras and fastest processor.
The ZenFone 4 Max can act as a power bank and charge other devices thanks to the included OTG USB cable.
It has a similar dual camera setup to its pricier stablemate, but although the 13Mp main camera has extra resolution, it doesn’t have optical stabilisation.
