The Asus Zenfone 2 ZE551ML is an all-rounder in terms of performance. The mid-budget smartphone provides a robust configuration, supremely engineered camera framework, a whooping storage space and a premium display to cater to all the needs of the users.

The All-rounder
Display and Design

The Asus Zenfone 2 ZE551ML features a massive 5.5-inch Full HD (1080 x 1920 pixels) IPS LCD capacitive display equipped with multitouch and can produce 16M colours. With a pixel density of 403 ppi the display architecture generates decent viewing angles and a wide arrayed colour spectrum. It is also equipped with useful features such as accelerometer, compass, gyroscope, humidity sensor, IR gesture, proximity sensor etc. Designwise, the Zenfone 2 resembles with HTC M9, latest flagship from the Taiwanese smartphone maker. The phone comes draped in a 10.9 mm outfit and weighs 170 grams only. The most impressive feature spotted is the Corning Gorilla Glass 3 on the top to protect the phone from accidental damages.

The smartphone sails on the latest Android v5.0 (Lollipop) OS with the very intuitive Zen UI on the top which makes it heavily customisable, almost like CyanogenMod. The device is empowered by a quad-core processor clocked at the speed of 1.8GHz and sits on a Intel Atom Z3580 chipset. To make it more efficient, the CPU has been juxtaposed with a whooping 4GB RAM and a PowerVR G6430 GPU. The good quality processor along with a powerful RAM ensures uninterrupted multitasking and allows users  to run multiple apps simultaneously, surf the web with shorter loading time, stream beautifully lag-free videos and enjoy a premium gaming experience.

Camera and Storage

The Asus Zenfone 2 ZE551ML is armed with an impressive 13MP autofocus rear camera with dual-colour LED flash. The much talked about dual-colour LED flash assesses the quantity of warm yellow and cool whites to emit the exact amount of light needed. This is done by analyzing the colour temperature and the entire ambience and thus, it is also very effective in low light conditions. It facilitates Full HD video recording at 30fps. The camera also comes with features like Face detection, Geo tagging and High Dynamic Range mode (HDR). The device also packs in a 5 MP front snapper which is very effective in video calling and capturing good quality selfies. In terms of storage space the device ranks high as it comes with a 32GB inbuilt memory and can be further expanded via microSD card (up to 128GB). 

Battery and Connectivity

The smartphone is fuelled with a good 3,000mAH Li-Po non-removable battery that delivers an average talk time and standby time on 3G. On the connectivity front, Asus Zenfone 2 ZE551ML includes  Bluetooth, Wi-Fi 802.11, a/ac/b/g/n with hotspot, 3G, 4G LTE cat4 50, GPS/ A-GPS, Glonass, USB connectivity, DLNA, NFC, GPRS and EDGE.

Best Phone Ever in 20k range After 1.5 week of usage
03 Jun 2015 By Shivam Kapoor On

I bought ZenFone 2 -1.8 Ghz because 2.3 GHz was out of stock and I'm kind of impatient :pnnFrankly, Asus ZenFone 2 is the BEST phone right now in the market having features of 50k mobile in 19-20k. The phone had some problems in starting 2 days but if you know how to fix those little problems you will be having the most fantastic phone in your hands with your friends glaring at it jealously :DnnVERY IMPORTANT - nAfter buying phone PLEASE PLEASE PLEASE first of all do an software update of 150 MB and PixelMaster update of 90 MB (From Playstore).nnFirst of all Thank you Flipkart for super fast and super awesomely packed Phone delivery. To count Pros and Cons -nnPROS -n1) Full HD screen wih the most amazing touch - You will love it.n2) Transitions - The effects added in this phone are purely awesome. I repeat awesome.n3) Freedom to Change anything - You can even change grid size, sliding preferences, themes, icon packs yada yada lock apps feature is already installed.n4) Battery - People will say the battery sucks....finish in 4-5 hours which is COMPLETELY WRONG. I will explain later in problems section.n5) Front Camera - Front camera is like pure bliss. To get so awsome pics from 5 MP camera is exceptional.n6)ZenUI - the UI is super awesome...the icons look so cool and eveything looks so clear.n7)EVERYTHING - everything is awesome in this phone :DnnCONS -n1)Back Camera - Back camera when used in 13MP setting captures pics with yellow tint although when clicked with 10MP the pics are really good.( ASUS knows about the problem and they are going to fix it in next update).n2)Bloatware- ASUS comes with lot of useless apps that can't be uninstalled or even disabled...not that they cause any inconvenience but totally grinds my gears.n3) SIM 2 doesn't support 3G - depressing as all other ZenFone allows....but i can live with it because not like anyone buys data on both sim.n4) NO earphones and charging cable is short- as much as it sound as a isn't as only SAMSUNG is providing earphones with mobile nowadays and no one else...not even HTC. You can always buy a new long cable beside crying -____-nnPROBLEMS I FACED - n1) Battery Callibration- This is a commn problem in ASUS ZenFones. The battery callibration is wrong. your mobile thinks 35% is 1% and switches off at 1% .It got me scared and i was totally gonna replace the phone but then i found out it's a common problem and i fixed it.(Google have all answers :D)nnSOLUTION - Proximity sensor - My phone goes black when i call someone and I can't even cancel the call. I found out it was my fault all along.nSOLUTION - You are using WRONG screen guard which covers proximity sensor so when you call someone it always think its near your ear and keep the screen off. Please buy official ZenFone 2 screen guard or tampered glass.nnPROBLEMS WHICH PEOPLE RAISE WHICH ARE TOTALLY WRONG -n1) Phone get heated up when charged - TOTALLY's always cold....the problem is maybe you are using lot many apps or lying.nn2) Battery is less - ZenFone 2 have 3000 maH......more than 90% phones in market. If your battery is dying fast then maybe close all the apps by clicking on recent apps button and clearing all the shit. PLUS Asus have application manager which solely is made to save battery and power saving app...After using all these 3 things,my phone when charged to 100% goes on for a full day... which is a lot...if you are looking for a phone which should work 2 days you are free to buy NOKIA 1100 if it's still in market :)nn3) 3G is slow - I have AIRTEL sim and 3G works faster on ASUS than it did on HTC and SAMSUNG (previous phones i owned)....seriously Don't worry :)nn4) Sound is LOW - THIS IS THE MOST RIDICULOUS..... The phone have so loud speakers. They are just awesome...the quality of sound is also cool. If you are having problems with earphone there is an installed app - AUDIOWIZARD...kindly use it :)nn5) Phone disconnects and low sound - TOTALLY WRONG..please configure the settings or use ASUS assistance app :) nn6) phone rotates, restarts blah blah yada yada reviews here - TOTALLY WRONG....i was scared too but this phone doesn't have any of those problems...Don't worry trust me....the people who write these don't know how to turn off auto rotation or other things.nnNOTE - These are totally bogus complaints....I never faced any of these.Please Stop spreading useless reviews.nnRECOMMENDATION - nThere are two apps in your phone MyASUS and ASUS support. Please take use of it fully especially CHAT SUPPORT in MyASUS app.( it's fast and they solve ur problems)nnFinally, sorry for making you read this much long review but it was necessary to tell people about everything. I hope I covered everything. Please like this review to make it to the top so everyone can get solutions to the problems and also because it took me 30 mins to write ***exhausted face*** :P

    The ZenFone 3 packs a 3,000mAh battery, with USB Type-C standard fast-charging, which looks quite good if you consider the industry standards and other hardware details of this device. On our standard video loop test, we got over 8 hours of continuous video playback, with the brightness pumped up to maximum, and some apps running in the background, and the WiFi turned on. 

    But in real-life usage, the ZenFone 3 fared better. Under heavy usage, with the network being alternated between WiFi and data, we got to run the ZenFone 3 for an entire work day, needing to top up the battery only in the late evening, just before the cab ride back home. The work day would start typically at 9.30 am, with the battery charged fully, and through the day we would use the device to consume media, browse through a lot of viral videos on Facebook, play all sorts of games, check out Instagram frequently and also make a few calls, and we would need to top the device off only by 7.30 pm, where it would have 20% of charge left. On moderate usage, however, while using the ZenFone 3 as a secondary phone, with many power-saving methods applied, we did manage to squeeze out a little more than a full day of battery backup from the device.
