I have been using Asus Zenfone 5 since 1year and it has never irritated me.
As I am a tech guy I rooted it after 2 months. It’s battery can also be increased by rooting it and using apps like Greenify, Cpu control apps. I personally like this phone as it have 2gb ram and its the best phone in its price which is?10, 000. I recommend this to everyone who wants a good phone under the price. You can also play high end games on it without lag and glitches. It also has a great Ui which makes it easy to use.
