The overall performance of the phone is very good. I did not feel any lag and multi-tasking was effortless. Yes, the phone does heat up at times, especially when it is doing something online. But that does not affect performance at any point. The phone has a superb benchmark score just above the One...

What's good

  • Snappy performance
  • Vivid and crisp display
  • Sturdy build

What's bad

  • Suffers from bloatware
  • Slow shutter speed
  • Not bright enough for sunlight legibility and too bright for night-time use

Asus hopes to make its mark in the smartphone market with the ZenFone 2 – a good unlocked phone offered at a relatively low price. It doesn't feature any premium materials, instead flaunting an all plastic build with a brushed aluminum finish. The finish combined with the curved back made it very comfortable for reviewers to hold while also providing a good grip. With that said, at 6 inches tall and 170 grams, many did find it to be a bit unwieldy and bulky.

The 5.5 inch IPS LCD display offers a full-HD resolution of 1,920 x1,080 pixels. While not as sharp as QHD screens, critics describe the screen as crisp with barely any discernible pixels. They add it offers excellent viewing angles and bright and vibrant colors though blacks tended to be a bit lighter than they expected. The only downside was in the screen's brightness. Many found it didn't get bright enough for good sunlight legibility or dark enough to comfortably view in the dark.

The ZenFone 2 offers two configurations: a 1.8GHz quad-core processor with 2GB of RAM and a quad-core 2.3GHz processor with 4GB or RAM. Experts all received the 2.3GHz quad-core version. When put to the test, it performed admirably during everyday use without a hitch and even when they started to put more pressure on the CPU with multitasking they didn't notice any problems. With that said, they add it does take a bit longer for apps to load and there were occasions where it got uncomfortably warm.

The biggest issue with the ZenFone 2 is the amount of bloatware preloaded on the phone. In total, experts counted 67 installed apps, many of which they immediately uninstalled to open up space. Battery life is decent though not great providing them with around a full day of juice with moderate usage.

At such a low price point, reviewers were expecting a more mediocre camera experience. For the most part they were proven wrong. Their pictures were generally detailed and accurate though it lacked the contrast of higher-end phones. The camera app provides 17 different modes to choose from though most either stuck with Auto or HDR. Surprisingly, low light pictures turned out fairly well thanks to the low-light mode PixelMaster, though critics point out that without optical image stabilization getting good low-light shots required a very steady hand. The biggest complaints were with its overall speed and poor focusing abilities. Still, consider it perfectly passable for posting photos on social media sites.

At the end of the day, most reviewers recommend the ZenFone 2. Android Central states, "If you're looking for a larger phone and don't need to have the absolute bleeding edge in every single aspect…the ZenFone 2 is here for your consideration." The Verge adds, "The ZenFone 2 still makes a fantastic package considering what you're paying." On the other hand Gizmodo says, "The ZenFone 2 is a fantastic phone for the money, but OnePlus redefined how much phone you could expect…"

The perfect example of why unlocked phones will rule the market in 2016

from Android Guys

Overall I could not be more happy than to start my journey into the budget to mid-range devices with the Asus Zenfone 2. I picked this phone to start with, because I know Asus has a great track record for creating great products at affordable prices like the Nexus 7. Intel has also proven to be quite impressive, with its relatively unknown mobile Atom chip, as it performed incredible smoothly paired with 4GB of RAM. 32GB of internal memory should be the minimum all devices come with these days, and having expandable memory is a bonus too...

Should I travel overseas I will definitely be taking advantage of the second SIM card slot. The absolute best feature of the Asus Zenfone 2 is that it can be purchased brand new for less than $250. That’s half the price of the Nexus 6P and $500 cheaper than the Samsung Galaxy Note 5. It truly makes me question why you need to spend the extra money on a flagship device. There will always be a market for flagships phones, but unlocked budget and mid-range devices are definitely worth taking a gander at. The Asus Zenfone 2 is a rock star when it comes to performance versus price.

The ZenFone 2 Laser is, in mostly every way, the same as the ZenFone 2. The differences lie under the hood, which translates into a slight drop in performance, and in features, the most notable of which is laser-assisted auto focus. The price starts at $199 USD, putting it in the sweet-spot budget range for many. As with the ZenFone 2, if you're on a compatible network and you're upgrading from an older or lower-tier device, you'll be very happy with the ZenFone 2 Laser -- it is stylish, has a robust camera, excellent battery life, and solid overall performance.

Asus's latest inexpensive phone hits most of the right notes

The Asus ZenFone 2 is the very definition of a "budget" phone; it doesn’t have a curved screen, it’s not at all water resistant, and it certainly isn’t the most attractive piece of hardware out there.

The Asus ZenFone 2 is the very definition of a "budget" phone; it doesn’t have a curved screen, it’s not at all water resistant, and it certainly isn’t the most attractive piece of hardware out there. But Asus found a way to pack the ZenFone 2 with a bunch of value, and not at the expense of its overall performance.

For $200-$300, you’re looking at a smartphone that can handle day-to-day tasks nearly as well as its twice-as-expensive competitors. Its battery life is commendable, too, running circles around phones like the iPhone 6 and giving flagships like the LG G4 and the HTC One M9 a run for their money. In essence, it's big, inexpensive, and it runs Android with ease.

Hardware prowess, software slump

from TechnoBuffalo

The Zenfone 2 is a device that flew under the radar of many in 2015. As the year closes out, it’s still a fantastic phone at a great price and compares very naturally to the OnePlus 2 that is oh so hard to get your hands on. I can very easily recommend this phone to anyone shopping in the $300 or under price range.

Most things handled well, despite heavy skin; but a disappointing camera

from tech2

Asus Zenfone2 presents a good overall package with high performance numbers. But the excessive bloatware can be a concern for many buyers. While Asus may think it is adding value for its users, not everyone likes unnecessary software shoved down their throats. The least Asus can do is give the option to uninstall unwanted apps.

A great value phone

The ZenFone 2 runs Android Lollipop with Asus’ own ‘ZenUI’ extensions.

The ZenFone 2 runs Android Lollipop with Asus’ own ‘ZenUI’ extensions. ZenUI basically conforms to the standard template for manufacturer customisations – tweaked icons, slightly modified core apps and a sprinkling of add-ons of varying utility. Privacy protection tools, a kids mode and downloadable themes are the highlights but on the whole the software build feels well done and not excessively heavy.

An Intel processor is still something of a rarity in an Android phone, but the ZenFone 2 demonstrates perfectly why it really should be a consideration. Despite having the slower of the two processors on offer, the device really flies.

The 4GB RAM no doubt helps when running lots of big applications, but we saw instant responsiveness, no tangible lag and overall performance that matches or even eclipses that of the very highest-end Android phones you can buy today. Given that the 1080p device performs so well, we expect that the 720p phones would feel blistering fast. We’d have no hesitation recommending the ZenFone 2 from a performance perspective.

Heavyweight contender

The Asus Zenfone 2 is not a smartphone you fall in love with at first sight. And yet, it’s one of the best midrange phones around, with remarkable battery life, a great screen, and powerful processors that can do anything you’d ask of your mobile. Between the two versions, I’d recommend the cheaper one—the low cost and huge battery easily make it one of the most interesting devices in the under-$200 price range...

If you’re willing to spend $300 on a phone and you crave the outsider chic that the funky Asus hardware offers, there are better options than the spec’d up, more expensive Zenfone 2 model. Consider instead the OnePlus, the Alcatel Idol 3 or the Sony M4 Aqua.

Overall the Asus Zenfone 2 (ZE551ML) offers a good value for money, offering good performance and 4GB of RAM at a price tag of Rs. 19,999. There are several improvements in the Zenfone 2 in the display and performance compared to the first Zenfone series. You also get 32GB of internal storage with expansion slot, which is rare to see in smartphones in the price range. Camera and battery life could have been better. Even though it has dual active SIM support, lack of data in the secondary SIM slot might not be preferred by everyone looking for a dual SIM phone.

Don't judge this phone by its cover

My experience with the 4GB variant was relatively positive—enough that I feel like the ZenFone 2 is worth its $300 price tag right off the lot. It’s an unlocked phone with dual SIMs and a memory expansion slot, in addition to 64GB of storage. It supports a large library of LTE bands around the world, so you’re covered almost anywhere you go with the ZenFone 2 in tow.

As far as mid-range phones go, the Moto G still succeeds for its fantastic front-facing stereo speakers and clean near-stock Android interface, but if you’re looking for something a little more powerful with a slightly better camera, the ZenFone 2 is worth considering.
