I’m thinking of buying a new mobile , still checking around for mobile so i want more input

What i want in my mobile

1- battery life , i don’t want something i have to charge everyday
2- i can use contact list / messages on my PC , i can EDIT them ( most important )
3- Above 2 Mega-pixel Camera & can record Video
4- price tag between 100-200 KD

Would be nice but not that important
– Wifi

Any recommendation ?
