Asus Zenfone 5, analysis


Asus is one of the manufacturers that has grown riding the wave android, although Taiwan has cost them positioned between the smartphone catalog after starting the ranges of tablets and smartphones with its successful hybrid Asus Transformer devices.

Con the Zenfone Asus has finally managed to bring to market a range of attractive smartphones, which as you will see in this Asus depth analysis of Zenfone 5 not penalize performance or user experience despite adapt to terminals compete with prices more content


Asus has done strange things, or terminals with high-end nomenclature and surname “mini” or “lite” or countless similar smartphones to confuse the user.

Rather, it has simplified its catalog to a minimum, leaving the high end to the fate of híbrido Asus Padfone , which has not come to our markets in the last generation, and presenting a complete family of smartphones under the name Asus Zenfone , three devices are differentiated by size and maintain the strategy specifications compensated with attractive prices.


The Taiwanese firm has spared to finish their Zenfone, but really is not who has done wonders in building This Asus Zenfone 5.

The device is made entirely of plastic materials , but his touch in hand is better than good because similar to the Teflon finish which prevents fingerprints and gives a great feeling.


The back cover is removable and also occupies the frames of the device, taking the side, metal keypads and with a pattern of concentric circles, same design used screening for the lower part of the front, below the screen.

The microUSB port is placed in the bottom of the terminal with microphone call in the top frame have the audio-jack standard 3.5 mm for headphones and microphone for video recording and noise cancellation, while the power and volume buttons are on the right side.

Asus has maintained a clean design on the device, simple and Smart , without gaps for bragging beyond the capacitive keypad dedicated, although there are three negatives greatly lower your grade Zenfone 5 of this section.

On the one hand, the removable back cover would be a plus but it was because you can only access the double slot microSIM or port for microSD memory cards, without possibility of exchanging the battery easily.


In addition, the speaker on the back too is always a negative, but here is a lesser evil compared to great handicap of this Zenfone 5, its dimensions , is that the device fail very little the front for panel 5 inch .

If we compare the size of Zenfone 5 with its competition, 148.2 x 72.8 x 10.3 mm with 145 grams , will lose almost all the battles for equal diagonal screen, although in this case we must recognize that be 5 reales inch by having dedicated keypad.

Display and hardware

Obviously, we should not expect too many concessions in hardware a smartphone that will leave its price below 200 euros although a sufficient performance for most users have seen that are indeed possible.

Asus has wanted to reduce the maximum price your Zenfone, but without impacting on a nice enough user experience, so the Intel hardware platform is accompanied by a good cast of specifications which more later.

First let’s talk about your screen, a panel made with IPS technology , 5-inch diagonal HD resolution 720p (1,280 x 720 pixels). The pixel density is 294ppp, so the sharpness not be a problem but the psychological barrier of 300 pixels per inch is not exceeded


A picture is worth a thousand words, so you just up here we have left fore panel This Asus IPS Zenfone 5, a screen that seems good, with the virtues and defects of the IPS , technology in the middle of an actual device but no boast.

The color reproduction is acceptable, natural and without excessive saturation , but obviously it’s a much less flashy than the AMOLED panel used by Samsung.

The brightness and outdoor vision is perhaps the aspect that could be improved, but not by that we mean Asus has assembled a bad screen but quite the opposite, because the Taiwanese manufacturer has opted it safe to IPS technology.

On the hardware of the device, we know that you like the data to compare, so begin by the specification table and then go shelling its capabilities and performance:

The Asus Zenfone 5 is a device of economic court, but not bad ready for daily use of any average user . Surely advanced users will miss a little more power in the chipset, although the 2 GB of RAM can make it run smoothly any game or application.

In fact, the Intel Atom Z2560 chipset GPU PowerVR SGX544MP2 shown more solvent than the Qualcomm Snapdragon 400 , the most used among SoC devices that will direct competition Zenfone 5, especially in the graphics tests.

As mentioned, also thank the 2 GB of RAM memory, more than enough to move Android 4.3 Jelly Bean update to Android -you have no problem 4.4- and 16 GB storage, as most tend to stay in the 8 GB.

For lovers of numbers, the available RAM factory for applications is nearly 1,400 MB, while the internal storage has more than 11 GB of space for the user.

In normal use have not noticed flaws or lags , Android moves fluid through ZenUI and have been able to run games and applications in multitasking without problems. Solvency despite its economic court, that’s the best description for Asus Zenfone 5


To complete the device hardware without getting too much in performance, discussed below, it is noteworthy that falls LTE connectivity from the list, then Zenfone 5 supports mobile networks to HSPA + .

There is also WiFi, aGPS and GLONASS, Bluetooth 4.0 and an FM Radio that lately not too valued and the usual battery current sensor without entering smartphones fingerprint readers or health sensors Samsung has taken his other middle range. On the contrary, we have no NFC chip.

Performance and autonomy

The turn to the overall performance of the terminal, but as you may have noticed we’ve been a little above in the previous section.

have already mentioned that Asus has sought the best quality / price ratio, but the Taiwanese have chosen a hardware platform very interesting , which hardly had tested and has us pleasantly surprised by its performance. First good news for Intel.

As a rule, the Asus Zenfone 5 will be perfect for most users smarpthone, which fulfilled the expectations will have a terminal with good screen and performance Solvent daily, without excessive price rises. Second good news for users.

It is true that we rejoice to see a smartphone that has managed to perfectly compensate for their hardware, to compete with terminals economic court does not penalize excessive users experience. Third good news for Asus.

All happy because with this Zenfone 5, to which we have not forgotten to make our usual battery of performance tests . Cold numbers yet many people like:

reviewed and the power that is able to give the Asus Zenfone 5 is when talking basic aspects that commonly overlooked in the analysis as their telephone functions, sound, touch, or more importantly reply autonomy.

No phone pales as compared to other end of the range we tested. The call sound is good , and network connectivity as well, although as we have said we have to settle with access to the 3G network.

The sound of the main speaker is acceptable with good volume, but is obviously limited by the situation on the back of it. With the terminal perched on a flat surface decibels lost, but I think you go to lose any calls.

As a general answer is not much to comment on, the autobrillo works well, and the multi-sensor the screen is capable of recognizing up to 10 simultaneous keystrokes, something that surprised us because this type of terminals usually have up to 5 digitizers multitap.

The autonomy of the terminal it will not surprise anyone, because battery of 2,110 mAh is what it is , although in fact the terminal has behaved acceptably well in this regard.

No think that you will get rid of a load every 24 hours, but we can ensure that the Asus Zenfone 5 is able to hold a day of fairly intensive use without any problems.

The best in this sense is to put numbers to quantify better, so we attach capture PCMark estimation in terms of autonomy in use of the device, which surprisingly reaches 5 hours continuous .

We say surprise because it is an even better reaped by the LG G3 S data with a significantly larger battery, 2,540 mAh.

Even with all autonomy is never an aspect to stand out in a smartphone, it will remain fully dependent on an electrical outlet each day if you want to hold live our phone.

We know it is fashionable and so we questioned separately, as the custom software for Asus -of which more later-also a specifically for energy saving.


The Zenfone five will not go down in history as the mid-range smartphone with better camera, but neither is lame in this regard thanks to its rear 8 megapixel sensor with LED flash relevance, autofocus, HDR and video recording capability in FullHD.

Meanwhile, the front camera of 2 Megapixel features 720p HD capabilities, and remains Justito for videoconferencing or quick shots.


The camera response is acceptable for its price range , good in conditions favorable light, when we can obtain images of sufficient quality although obviously suffering indoors or in varying light, noise where we appear.

Here is an example of a decision made under favorable light conditions we leave, and its wholly owned enlargement showing a definition pretty good.


The camera is in tune with which it was mounted in the high range a couple of years ago, and without wishing to be left at home the traditional camera to take pictures of higher quality, yes can get us out of trouble in many . moments

Here you have a gallery with several shots taken by Asus Zenfone 5 full size and unretouched:

Obviously, seeing an analysis published on Engadget Android, the Asus Zenfone 5 has opted for the mobile operating system from Google, although in this case to remove the device from the box you will see Android 4.3 Jelly Bean.

You can upgrade to Android 4.4 KitKat, but always will see Zen UI in masking the Android interface , as Asus also wanted to leave their touch of color in the software of your Zenfone range.

Not a customization too intrusive , and indeed can say that is content with a few design modifications to adapt Android to the aesthetics of Asus


Like almost everyone, Asus has chosen a custom lock screen , with shortcuts and planning of daily tasks, as well as has included some proprietary application as SuperNote to take quick notes, or WebStorage, access to the hard drive in the cloud Asus.

As mentioned, there are a couple of applications for advanced configurations , namely to set specific energy saving modes, and another that will serve to calibrate the screen to our liking.

No traces of Material Design and pre-Android 5.0 Lollipop adaptations, but not be surprising, given the simplification of catalog Asus, the Taiwanese may soon launch an official to the latest version of Android update.

It would certainly be more than good news for users, plus a huge boost to improve the view of the general public about the Asus support. We will see over time if Asus decides to launch Android 5.0 for Zenfone .

Asus Zenfone 5, the opinion of Engadget Android

Deciding on mid-range smartphone is increasingly complicated , hence the market saturation by the amount of good choices that different manufacturers have been launched in recent months.

This is the range best selling, although these terminals no outbreaks of the flagships are carried, and knows that Asus has decided to leave the competition by Android around to focus on designing a range of attractive terminals seeking the best value quality / price . The Asus Zenfone 5 stems from these premises.


The sensations that has left us very positive Zenfone 5 , had not tried too the Intel hardware platform, but its solvency is beyond doubt and thanks to This user experience Asus smartphone is more than good.

Its size is its main stumbling block , and surely the Taiwanese manufacturer could do much more to the front harvesting and the final dimensions of Zenfone five were better But that would surely quite expensive a terminal, however, has remained below 200 euros.

It may be difficult to justify buying a terminal end current average above the barrier of 200 euros, especially when the OnePlus One round these prices a little above, but below that barrier sure the Asus Zenfone 5 is one of the most interesting options.
