Dad's a business man, does a lot of talking on the phone, and prefers a simple UI(windows 
). I've got my eyes on Lumia 720, the battery performance seems better than 620 or 520, though I'm not entirely sure. I'd be grateful to hear any brief reviews from the 720 users or other suggestions under 15k would be appreciated. Thanks
EDIT-
Sam's Questionnair-
1. Budget? Around 15k
4. Preferred choice of brand? Nokia, Lumia series.
5. Preferred input method (QWERTY, touchscreen, numpad, touch-n-type). Touch, of course
7. Preferred operating system? (Android, Symbian, iOS, Windows Phone etc). Windows.
10. Primary use of handset (multimedia, camera, mails, internet, gaming etc)? Well, Dad's a business man, so...
11. Any specific mobile phones in consideration? You tell me, but the priority is UI simplicity and Battery performance.
