The worst phone in the world. Review on Spice XLife 480Q

I had purchased this phone few months back. but I got a terrible experience with this phone.I bought a full white colour phone which has 4.5 inches qwvga screen.The most worst thing about this phone is the battery.this phone is only 1700 mah battery which is very annoying .this battery lasts for only 13 -14 hours.this phone has 3g connectivity but I didn't get so much Internet speed in Vodafone 3g .the phone comes with a 512 mb ram and quad core processor but after launching a big application the phone starts getting hot and a little laggy also.the most worst thing in the phone is the os problem.when I turn on the data connection, some unknown apps starts downloading automatically without any notice .I also turned off the unknown resource from the setting but after some moment it turned on automatically. I request everyone not to buy this phone.
