[ZenFone 2 General] jerflash:
​

In this review i am looking at Asus’s flagship phone for 2015 the Zenfone 2 complete with 64gb of storage and 4gb ram (most in any phone to date). As a flagship it is going up against some stiff competition such as the Galaxy S 6, the LG G4, and the One M9. With the specs Asus’s top version of this phone boasts it fits well into that crowd but there are areas that they did need to “skimp” on in order to reach that magical $299 unlocked price. There is a lower spec’d version of the Zenfone 2 for $199 unlocked but it does come with a slightly slower processor and 2gb of ram. We shall be focusing on the higher end one here.

Look & Feel​

As you can see from the pictures i was able to grab the red version of the phone. i’m a huge fan of red so any phone released with a red option already gets a bit of an edge in my mind but i won’t let that come into my decision here. I do like that they left the front of the device all black so all you can see in the front is the small chrome speaker grill, chrome Asus logo and the hardware keys. I think it looks rather tastefully done and it does have the premium look that many seem to want these days.

The back of the phone is plastic but they do a good job hiding that a bit with a “metallic” finish with a bit of texture that help in keeping a grip on what is a large phone. It is not a fingerprint magnet by any means. In my opinion it feels even a little better in hand then last years LG G3 even is the Zenfone 2 is a bit taller thanks to those hardware keys. I personally am not a fan of these but many are...all comes down to your taste. Taking more design cues from LG the Zenfone 2 has its volume rocker is on the back. They did opt to put the power button in my opinion the worst spot on such a large phone... Dead center on the top of the device. Not only that... It's also quite "mushy" giving little to no tactical response to let you know you actually pressed it. The Zenfone 2 does have double tap to wake and sleep function as well but it did not work as intended to me all of the time.

The device’s dimensions are 152.5 x 77.2 x 10.9 mm (6.00 x 3.04 x 0.43 in) and weighs in at 170g (6.00 oz) It is a bit thick but the sides slim down to 3.5mm which make it much nicer to hold. What i will say is where the front glass on the phone meets the small “chin” below the hardware keys there is a very noticeable sharp lip. Not enough to hurt but enough to become annoying in my short time with the phone. Overall it’s a well designed phone and for the price.

​

Under the Hood​

Under the back cover you will find a micro SD card slot for up to 128GB of expandable storage and 2...count them 2 sim card slots. This is a bit strange to have in a phone in north america but very common in other areas of the world. I did test this out and switching between phone numbers was easy enough but only sim slot 1 can handle 3g and LTE. The second slot is only for 2G and Phone calls. Inside you will also find a 3000mAh battery but this is not user removable which is a bit of a shame but that’s the way most phones seem to be going. Do note that this phone comes with Intel’s version of quick charge and the $299 version of the phone comes with a high amp quick charger. It does work with all chargers with Qualcomm’s Quickcharge 2.0 spec as well.

User Interface​

The Zenfone 2 comes out of the box running Android 5.0 Lollipop which is nice to see. I did receive an OTA right after turning on the device but the version number stayed at 5.0. Everyone is now waiting on phones to get 5.1 but Asus am an interested to see how up to date they keep their not flagship. I will say that this phone as the most “bloatware” I have ever seen on an unlocked device. Even comes running Cleanmaster out of the box...classy. Asus is nice enough to let you uninstall much of it but for the review I wanted to keep most of it intact. I did uninstall Cleanmaster as it was just too annoying to deal with. I do however like that almost all of the phones apps live in the Play Store and can be updated without having to wait for a full firmware update. Nice moves.

Over all Asus stuck to the material design aspects of Lollipop with its revamped ZenUI. The menus are in list view and are easy to navigate. The notifications pulldown is close to stock with few differences but the quick toggles have been completely re-skinned and are customizable. I actually like the way this works and give you a quick brightness slider and access to some of the tools you may use most often on your device.

The only part of the UI i really have a problem with is the one you see most often...the launcher. To get into Google Now you must long press the home button then swipe up... not the most intuitive or the best implementation of this feature. There is also no google now hotword support built into the launcher. It took me about a day to install the Google Now Launcher and all is well.

Performance​

One word can describe the performance of this device...Fast! With 4gb of ram to work with i would expect nothing less. Couple that with the Intel Atom Z3580 clocked at 2.3GHz (Intel Atom Z3560 1.8 GHz in the 2gb version) and this thing is a screamer. I have had Zero slowdowns or stutters since i started playing with it and that is also after loading it up with all of my personal apps and having all of my accounts syncing all of the time. Pretty great!

On the graphics and video handling of this device it was again very good. Running the PowerVR G6430 (same as the iPhone 5s) it has no problems playing some of the most intense games. Its pushing a 1080P screen so not as many pixels as many of the other 2015 flagships. I do not run benchmarks on my phones but can tell you that you will not be disappointed.

Display​

The phone boasts a 72% screen to body ratio which is not too shabby. It comes with a 5.5 inch 1080p IPS display which come out to be 402ppi and to my eyes it is perfectly adequate. Images look sharp and its 3 built in screen modes. Comes set on the balance mode out of the box but has a Reading to cool things down and a Vivid mode which really makes colors pop like on the GS6, even a mode to let the user make their own settings. I left mine on balanced. Where the display does not do well is with readability outdoors. It does not get bright enough to overcome even an overcast day. At the same time does not get dark enough when trying to watch a video or read a website in pitch blackness...my eyes did feel strained. The display is just fine but it is clearly one of the areas that Asus had to give a little to keep the price down.

Camera​

In the press and at the US launch event this is the one area Asus spent the most time talking about. Asus is very proud of this camera and they should be...it is quite good. Lets start out front where the Zenfone 2 is rocking a 5 Mega-Pixel, Fix Focus, Wide View, camera with Asus’s PixelMaster tech. It takes decent selfies and has many modes to help you tweak them to your liking. Out back is a 13 Mega-Pixel camera with Asus’s PixelMaster tech. While the mega-pixel count may seem low for a flagship phone today it actually takes some good shots. In good lighting it did very well. It does not has the optical image stabilization of some of the more expensive phones but it even does well in dim to low light situations. Not the greatest camera but one the best i have seen at this price point for sure.

Battery Life​

One of the most important specs in any mobile device and I am happy to report that the Zenfone 2 delivers in the battery life department. I an not easy on my phones battery. I have all of my social media as well as 4 google accounts and 8 other email accounts constantly updating in the background. While testing i kept the phone on auto brightness. With its 3000mAh cell I was always able to through a whole day with some to spare. As mentioned before it does not have a removable battery but the quick charging is definitely a plus if you have really been hammering on it for a few hours.

In Conclusion​

Asus really wants to make it clear that they are coming to play. The Zenfone 2 delivers in many areas and ticks all the right boxes for what most would want out of a flagship level device. With that said even though Asus is comparing this phone to the likes of the GS6, I am much more comfortable comparing it to the 2014 flagship phones from all of its competitors. The GS5, the LG G3, the HTC One M9, let’s even throw the Oneplus One in there… all still cost more when purchased new and unlocked then the Zenfone 2 at $299 for the top model. I think that is the biggest win here for Asus. Lets not forget that it starts at just $199 unlocked! That is what most flagships smartphone cost for their lowest spec model on contract.
