I will be comparing most of the aspects with Samsung Galaxy Grand 2 as it is my Primary Phone.
Model: Asus Zenfone 5 A501CG 8GB
1.6 ghz dual core intel atom processor with hyper threading
2 GB RAM
PowerVR 544SGXmp2 GPU
Android 4.3 (upgradable to Android 4.4 Kitkat)
5 inch HD IPS (294 ppi) display
8 MP auto focus rear camera with led flash
2 MP front Camera
Phone with Battery, Asus Earphones with ear plugs, Asus Charger, Asus Data Cable, User Manual, Warranty Card.
Zenfone 5 looks trendy and slim. Its built quality is very good. The back is made of plastic which is very soft to hands. Weight of the phone is 140 grams, feels much lighter then Grand 2 which weighs 163 grams. The phone is pretty slim, maximum width is 8.8 mm in center, from sides it is much more slimmer.
There is Notification LED which glows red when battery is low, Orange while the battery is charging, Green when the battery is fully charged, and Green if there is any notification. But the notification led is a tiny one, and is not visible from far away, only visible properly when you are looking from above the phone.
5 inch HD screen is a good one. Just slight color difference when tilted, otherwise good viewing angles. Colors are slightly dull in compare to Grand 2, say by 10%. Pixels are not visible as it packs a good pixel density of 294ppi. The display is quite reflective and you have to maximise the brightness in sunlight to view it properly. Also the display attracts finger prints easily. But the touch is very smooth and easy to operate. Corning Gorilla Glass 3 protects the screen from minor scratches, so you don’t need a screen guard for this one. Overall the display quality is a very good one.
Out of 8 gb internal memory, 4.8 gb is available to install apps. Out of the 2 gb ram, about 1.4 gb ram is available on first boot. Once installed most apps can be moved to external card (along with data)
The phone runs completely lag free. The dual core processor actually work as a quad core one as it supports hyper threading. Installing apps takes half of the time when compared to Grand 2. The phone heats up a bit while gaming or other cpu intensive tasks and specially if the screen brightness is set to high, but its not a major concern.
Volume of speaker is not very loud. But its still good. Ringtone is loud, vibration is strong enough. During calls the audio reception is not of a great quality (only at highest audio level), but again its good enough. Microphone is good, there is no problem hearing your voice at the other end. Asus headphones are good ones.
Camera captures pretty good photos. By default it captures photos in 6MP (wide) format. But you can change it to 8MP (4:3) in settings. Photos captured in daylight are pretty good. In low light photos are bit grainy. Led flash is good for near objects. Led flash is weaker by 10-15% compared to Grand 2. Still the photos are good as you can see in samples. Full HD video recording is also of good quality. Front camera is also good.

Running Antutu Benchmark gives a score of 19608 which is a very good score. Antutu benchmark suggests graphics quality to be excellent, fluently supports large mobile games.
Most of the games i tried run lag free even on high settings. These include Asphalt 8, Rayman Fiesta Run, Temple Run OZ etc
2110 mah battery takes about 3 hours to fully charge from 0 to 100% (with single sim and data off). The battery life turned out to be average specially if you are using dual sim. But i found the battery life good enough when using single sim with power saving mode set to optimized mode. Battery falls by 1-2% overnight (with single sim and data off). With less usage, battery can easily last for more then 2 days as is evident from the screenshot below. (2 days 22 hours on battery includes phone calls of nearly 1 hour, 2 hours of internet over wifi, power saving mode on all the time, data off all time)
Other Features :
USB On The Go (OTG) support.
Accelerometer, proximity, light and magnetic sensors
Dual Sim (dual standby). Both sims are Micro Sims and both supports 3G. But 3G can be used only on 1 sim at a given time. Both sims supports WCDMA and GSM
MicroSd slot for support of memory cards upto 64 gb. It supports MicroSD and MicroSDHC cards.
Dual Microphones, one at the top and one at the bottom
Notification Led is present
Glove mode to use the touch screen with gloves
Phone supports Hindi font by default, and hindi language is visible in Whatsapp and other apps. Punjabi font is not supported
Wifi Direct, Wifi Hotspot, Tethering through USB, via Bluetooth is present. Wifi works fine.
Asus Zenfone 5 is one of the best phone in the budget of Rs 10000 as of now. Asus also provides timely OTA updates to the phone, as you can see in the screenshot.
