Asus ZenFone 4 review


Zen and the art of smartphone design

Competent main camera ; Premium Metal and glass build ; Decent gaming performance

Power a bit lacking for the cash ; Beefy bezels

Probably doesn't signal the start of an Asus assault on our phone-buying habits, but the ZenFone 4 is perfectly potent - if a little too stuck in its ways when it comes to software

Asus ZenFone 4 review


The ZenFone range was originally unveiled during CES 2014 in January, but have only just been introduced to the UK. The ZenFone 4 is available to order from Asus now for a bargain £99.

For £99, we're impressed by the ZenFone 4. It's nicely designed, has brilliant software features, is suitably speedy and has decent battery life, but it's not outstanding. We'd like to see a slightly better camera and the addition of 4G connectivity....

Asus Zenfone 4


Is it hit, miss or maybe for Asus' Moto G rival?

Decent internal storage at the price, Fair day-to-day performance, Colourful design, Feature-packed camera app

Rubbish battery life, Non-IPS screen, Interface fiddly in places

Asus ZenFone 4 hands-on review


From our very limited time with the device we were actually surprised with its performance. Other smartphones in the ZenFone 4's price range are incredibly laggy to use; while this smartphone wasn't lightening quick, we didn't really experience any...

The Asus ZenFone 4 has the makings of a really good budget Android smartphone, it's got an incredibly cheap price tag and a good set of specs, if the device remains unlaggy in the long-term, like it did when we used the phone then it should be very...

Asus Zenfone 4 Review: In Depth


We review the Asus Zenfone 4, a £99 Android handset that's pretty small but still packs in some decent features, including a nippy Intel processor and 5-megapixel camera.It's never been a better time…

Easy to grip and use one-handed ; Nippy Intel performance ; Surprisingly good typing ; ZenUI well thought-out

Woeful battery life ; Moto G boasts sharper visuals ; Camera features hit-and-miss

ASUS ZenFone 4 Smartphone Review


Continuing our look at the ASUS ZenFone range – today we review the smallest of the lot, the ZenFone 4. Very competitively priced at just £99, the ZenFone 4 aims for those on the tightest of budgets but who still want a complete smartphone experience....

Pocket-friendly ; Decent camera ; Beautiful UI ; Very cheap at £99

Awful battery life ; Lots of bloatware ; Fairly thick

the ASUS ZenFone 4 looks a good option if you need a decent phone on a budget, though the Moto E 2nd Gen may be worth a look too.

Asus Zenfone 4 review - Intel power for £99


Announced earlier in the year but only just going on sale in the UK now, the Zenphone is a three-pronged Android smartphone series from Asus, comprising models with screen sizes of four, five and six inches. Here we look at the entry-level Zenfone 4,...

Good build quality, Powerful Intel processor, Attractive software

Average rear camera, No front camera, Poor viewing angles

Asus Zenfone 4 review: One of the best low-cost smartphones you can buy - Tech2


. Does the Zenfone 4 put up the same show in the budget category? Read our detailed review to find out.

The Asus Zenfone 4 packs lots of features into a tiny package. But the budget price means that the phone has cut corners, which is evident in the low-resolution display and underpowered processor and camera. Yet, there’s lots to like about the Zenfone...

Asus Zenfone 4 review


Good audio performance can't rescue the ZenFone 4 from its frustrating software.

Audio performance is excellent ; Reasonably priced

Frustrating software ; Performance can be sluggish ; Disappointing camera

Frustrating software made us lose our calm with the ZenFone 4, which is a shame when other aspects like the battery and audio performance are great for a phone at this price.

Review: Asus ZenFone 4 (A400CG)


Sleek and compact design; Solid construction; Smooth user experience; Excellent multimedia performance

Screen has narrow viewing angles; Battery could have been better

The ZenFone 4 is a great value handset that provides good smartphone experience. With this handset, Asus has proved that it is possible to deliver an affordable phone without compromising on the quality. The ZenFone 4's multimedia performance is better...
