ASUS Zenfone 4: Best budget phone in the market!

I'm stepping down after using a Galaxy Note 3 (which I lost,hence this phone in the interim),but I will to try to be as objective about the Zenfone 4 as possible.

1. Unboxing: The phone came in a stylish little box which slides out instead of flipping open. Contents include the handset, battery, 2-pin USB wall adapter and a data-cum-charging cable. Earphones have been omitted as an obvious cost cutting measure. The device has a sturdy look to it,though very plain. The concentric circle desig...

Moto Say hello to Asus Papa

Kudos to Asus and Flipkart for bringing such a great smart phone in India where we the (middle class) are at the mercy of some big brands to launch low feature mobile phones. Moto e came and changed the scenario a little bit. Still it had many shortcomings , such as a poor camera and no front camera. All these shortcomings have been removed by asus in this device.
You look at the phone and can resist yourself saying, "Wow such a great shape'. It is a kind of sexy shape.
apart of this you get...

Is this the Moto E killer?

Priced 1000 bucks less than the Moto E, this phone surely should get a lot of people interested.
Asus is an ace company when it comes to hardware and they have reigned at the top for quite some time. Unmatched quality of Asus can be determined solely by the fact that the Nexus 7 tablets are manufactured by ASUS.

And this phone seems to have it all.

A dual sim which is a standard for all phones now, with dual camera (5MP and 0.3MP).
Thats something the Moto E does not have. Moreover, it has ...

Better than Xiaomi Redmi 1S

After using the phone for about a week all i can say about this asus zenfone 4 A450CG is that it's simply AWESOME'
Key Points:
Asphalt 8 on high settings runs as smooth as butter and i mean it(just make sure to clear out your ram before stating the game) and same goes for modern combat 5 too.
Performance wise it's on par with nexus 5 i would say based on my experience with both nexus 5 and asus zenfone 4.5.
It comes with usable storage of 4.5 gb out of 8 gb
It supports otg natively

Smart enough phone for smart enough people

It's good to own a Hayabusa.
It's not SO good to ride it in city traffic.
Where the RD-350s can keep up with you.
What if the the RD were sold at the price of a RX-100 ?
That describes my journey from FlagShip Phones to Asus Zenfone 4
Everything I need to do in real life, it can do.
From fringe-area-calls thru navigation to heavy gaming.

"But does it have Electric Self-Start?" "No, but I have legs to kick-start it"
Yes, there are some small cons, but trust me, we can live with that...
For ex...

Was looking for a phone for about 3 months.
Finally I bought this for ?6300, and trust me when I say.. I didn't expect the phone to be so awesome when I ordered it.

Poor Battery Performance

The ASUS new Phone battery performance is very bad. It could be used for only for 3 hours after 100% successful charging. I am using very limited. Please do the needful. Preferably I want to return the phone and want to go for new brand say MOTO E or any other phone which can give me better battery life for same cost.
