I purchased zenfone5 from flipkart 2-3 days back all the features are good other than battery.
If you will charge the battery upto 100% and will not even use the phone for 5-7 hours it will consume the battery upto 40%-50% .after every 1 hour you have to charge the phone.its really disgusting .so I would suggest you not to purchase any Asus zenfone.
