Way back in 1989, asus started out as a consultancy service for motherboard manufacturers. According to lớn industry legend, asus got a leg up in the industry after designing a motherboard for Intel"s 486 CPU without access lớn a processor, even fixing problems that Intel"s own engineers had had.

Today, the two are still close partners, and hãng asus uses Intel"s sản phẩm điện thoại processors in its smartphones & tablets. Last year"s ZenFone 4 (Review | Pictures), ZenFone 5, và ZenFone 6 were runaway successes for hãng asus in India thanks primary lớn cutthroat pricing & dependable performance. Now, hãng asus has just launched a new series called ZenFone 2, & the company has been from shouting from the rooftops that the top-end variant has 4GB of RAM.
At the moment, asus is selling the ZenFone 2 in four different variants in India: the ZE551ML (with 4GB of RAM, 64GB ROM and a 5.5-inch full-HD screen); the ZE551ML (with 4GB of RAM, 32GB ROM và a 5.5-inch full-HD screen); the ZenFone 2 ZE551ML (with 2GB of RAM, 16GB ROM & 5.5-inch full-HD screen), and the ZenFone 2 ZE550ML (with 2GB RAM, 16GB ROM and 5.5-inch HD screen). To địa chỉ cửa hàng to the confusion, both ZE551ML (4GB) models use the 2.3GHz quad-core hãng sản xuất intel Atom Z3580 SoC whereas the ZE551ML (2GB) & the ZE550ML are powered by the 1.8GHz quad-core hãng intel Atom Z3560. Prices range from Rs. 12,999 lớn Rs. 22,999.
There are more variants of the ZenFone 2 which the company might launch later. This naming scheme will be really confusing for buyers, because the mã sản phẩm number alone does not mean anything. The folks at hãng asus could easily have avoided this hotchpotch of variants.
Nomenclatures aside, hãng asus sent us a review unit of the ZenFone 2 ZE551ML with 4GB of RAM và 32GB of storage space. We put the phone through its paces lớn find out if 4GB RAM actually makes any difference in real-world usage.
Look & feelWith the ZenFone 2, asus has engineered a radical kiến thiết change that is bound lớn invite differing opinions. The curve on the rear of the ZenFone 2 is slightly more pronounced, compared to its predecessor, the ZenFone 5 (Review | Pictures). Couple this with the brushed metal finish of the removable plastic back, and the phone reminds us of the điện thoại htc One (M8) (Review | Pictures), especially since our reviews unit was the Glacier Gray variant. All said and done, in our opinion, the phone does look premium.
The ZenFone 2"s form size falls somewhere in between that of the ZenFone 5 and the ZenFone 6 (Review | Pictures). The dimensions need khổng lồ accomodate a 5.5-inch screen, and the weight has also increased as a result. The phone has dimensions of 152.5x77.2x10.9mm & weighs 170g. Despite these numbers, the ZenFone 2 doesn"t feel chunky because of the curved rear. The phone can be gripped nicely but don"t expect it to lớn be comfortable to lớn use with one hand.
The most noticeable change is that the volume rocker has been moved to lớn the rear of the device. We saw such an implementation for the first time on the LG G2, & it then continued through LG"s subsequent releases. In LG"s phones, the power button is wedged in between the volume buttons, whereas on the ZenFone 2, the nguồn button is on the đứng đầu of the phone.
The problem with this placement is that it is difficult to reach while using the phone with one hand. The button is flush with the vị trí cao nhất edge, as a result of which usability takes a hit. Thankfully, you might never need lớn use this button because the software allows you lớn double-tap the screen to wake the phone or lớn put it to sleep. The volume rocker has a slightly ribbed texture và really good tactile feedback. It doesn"t matter if you are right-handed or left-handed; your index finger naturally reaches for it.
The placement of the physical buttons means the left & right edges of the phone are naked. The Micro-USB port and microphone are at the bottom of the phone. A 3.5mm jack và microphone are present on the vị trí cao nhất on either sides of the power nguồn button. Apart from the volume rocker, the rear side of the phone also houses the camera and the speaker grille.
The display takes up close to lớn 70 percent of the front of the ZenFone 2, và the bezel is fairly slim on all sides. The earpiece, front camera, ambient light sensor & notification LED are lined up above the screen. The phone has a row of capacitive buttons below the display, which aren"t backlit. Below them is metal "chin" which continues to lớn use Asus" trademark concentric circle finish. It adds a dash of character to the design of the phone.
Specifications & softwareOur đánh giá unit is the top-end ZE551ML variant of the ZenFone 2, which has the most high-end components of the lineup. The phone has 4GB of RAM, which is the first for any điện thoại cảm ứng thông minh we"ve reviewed. It also has a 2.3GHz quad-core hãng intel Atom Z3580 processor with an integrated PowerVR G6430 GPU. Incidentally, the same graphics chip is also used in the iPhone 5s. The phone has 32GB of internal storage space and there is a microSD thẻ slot which can be used to địa chỉ cửa hàng 64GB more space. Furthermore, the Micro-USB port can be used khổng lồ plug external USB drives in.
The phone accepts two Micro-SIM cards. The primary SIM thẻ can connect to 4G networks including the 2300MHz Indian 4G frequency band. Both SIM cards can connect to lớn 3G networks.Other connectivity options include công nghệ bluetooth không dây v4.0, Wi-Fi a/b/g/n/ac và NFC. The ZenFone 2 has a 13-megapixel primary camera with dual-LED flash and a 5-megapixel front-facing secondary camera. The phone also has a fairly large 3000mAh battery under the hood.
The 5.5-inch IPS LCD screen has a resolution of 1080x1920, which translates lớn a pixel density of 403ppi. Images look crisp & the colours are also accurately reproduced. Even the viewing angles are pretty good. The only weakness of this screen is that even at maximum brightness it looks a bit dull, which in turn affects the sunlight legibility.
Asus ships the ZenFone 2 with apk Lollipop out-of-the-box, coated with Asus" custom ZenUI skin on top. ZenUI is quite a departure from stock game android but adds a few neat tweaks that could be useful for quite a few users, và is as zippy as ever. For example, the Smart Group functionality in the phầm mềm drawer bunches similar apps together into folders, which comes in handy when you don"t want khổng lồ go through the trouble of sorting apps one by one. Similarly, the app Lock feature lets you add a password to any app, preventing others from opening things you don"t want them to.
Zen UI also allows for a lot of customisation, & you can change themes, icon packs & the homepage scrolling animation. The one-handed operation function has been tweaked slightly lớn allow more control to lớn the user - you can now manually drag from the corner of the screen to lớn set the screen kích thước without having to lớn make bởi with preset screen sizes. ZenMotion is another software feature that gives users the ability to draw gestures on screen when the phone is asleep, to mở cửa any particular app. Hãng asus also adds a in-house apps: hãng asus ZenCircle, a social networking tool for creators; PhotoCollage; WebStorage, a cloud-based storage solution; & Mirror, which lets you use the front camera và screen as a mirror.
CameraThe primary camera on the hãng asus ZenFone 5 was a competent performer. Unfortunately, asus has failed khổng lồ recreate that on the ZenFone 2. We consistently saw mediocre results with the 13-megapixel shooter, which should have been more powerful than the 8-megapixel one on the ZenFone 5. The average image chất lượng of the ZenFone 2"s primary camera is yet another reason for us to reiterate that the megapixel count doesn"t directly correlate to lớn camera quality.
(Click for full size)The sample shots from our daylight testing sessions were laden with over-exposed areas around the edges and colour burning as well. The sensor needs shade khổng lồ capture even half-decent images. We also noticed a fair amount of noise & barrel distortion around the edges in some daylight shots. Performance aside, Asus" camera ứng dụng is feature-rich & has a ton of shooting modes. The coolest feature of this tiện ích is that the Low Light mode pops up automatically the moment it detects that the light is not enough for the sensor khổng lồ capture all details. Shots are restricted to 3-megapixels (or lower) in this mode, but the tradeoff is worth it. Shots taken in this mode looked significantly more detailed and were better lit too. This is a better alternative lớn using the dual-LED flash for capturing pictures because they look artificial.

(Click for full size)As expected, the 1080p videos captured with the primary camera were not great either. In what is becoming the norm these days, the camera app has beautification options for the front camera. Anyway, the front camera captures warped images which could be a direct result of making the lens wider than the one on the ZenFone 5. The details are pretty decent, though.
PerformanceIf there is one area where the ZenFone 2 shines it is vi xử lý core performance. We zipped through general operations like opening apps and games. The speed is comparable to that of Snapdragon-toting flagship devices. The performance of the ZenFone 2 is so good that at one point we had more than trăng tròn apps & games running in the background & only 1.5GB of the available 4GB RAM was being utilised.
In the AnTuTu và Quadrant benchmark tests, the phone scored a healthy 32,086 and 20,523 respectively. We installed Asphalt 8 và noticed that it displayed the full range of special effects while running pretty smoothly. The gaming performance of the phone is corroborated by the benchmark results. 3DMark Ice Storm"s basic và extreme tests maxed out, whereas the Ultimate benchmark returned a score of 17,654. Similarly, the phone scored a healthy 30fps in GFXbench.
All our thử nghiệm videos played without any glitches but the sound chất lượng of the loudspeaker is not too great. Thankfully, our reference earphones sounded great when connected khổng lồ the 3.5mm headphone jack. Asus doesn"t provide a headset with this device. The sound chất lượng in calls was average; we noticed some hiss on our end and the connection dropped at least twice. The battery life, although better than its predecessor, is still not that great. It lasted 7 hours và 52 minutes in our đoạn phim loop battery test, and in daily use we had lớn connect it to a charger at the over of the day. Asus implements a fast charging tech that manages khổng lồ charge the phone pretty fast & could somewhat hóa trang for this performance.
VerdictWith the ZenFone 2, hãng asus improves on most aspects of the Zenfone 5 except for the camera. The 4GB of RAM could come in handy if you often have multiple browser tabs mở cửa at the same time. Also, the PowerVR graphics cpu is a solid performer và that is a boon for apk gamers.
The ZenFone 2 ZE551ML with 64GB ofinternal storage is priced at Rs. 22,999 whereas the 32GB variant will phối you back by Rs. 19,999. This means that asus is now competing with the xiaomi Mi4 (Review | Pictures), OnePlus One (Review | Pictures), và HTC Desire 820 (Review | Pictures) - all of which have better cameras than the ZenFone 2"s 13-megapixel shooter.
If you can live without 4GB of RAM, then the ZenFone 2 ZE551ML with 2GB of RAM & 16GB of storage space is available for much less at Rs. 14,999. The ZenFone 2 ZE550ML is available at the even lower cost of Rs. 12,999, which puts it in a different category altogether.
All said và done, our advice to potential buyers is to lớn carefully choose the right variant of the ZenFone 2 according khổng lồ their requirements. We understand that having so many SKUs of the same phone will be confusing, but at the same time we appreciate hãng asus for providing choices.
