My ideal smartphone is with a built in battery and can last 24 hours with high capacity. I prefer a latest model as much as possible to enjoy new features. When I buy a new smartphone, I always look for its features and user friendly phones. It's shouldn't be very expensive but with excellent design and features. I use my phone for work and downloading music videos and so it's important to have bigger storage. An excellent is also a big factor so I can enjoy taking pictures.
