This is a phone that is ages old. So I did not kid myself while buying this product. My requirements were good/average battery life, a hassle free OS, very good audio(i listen to music a lot) and an average camera.
Till now the battery life is good. With 3g and wifi usage it is almost 1 charge per day. However gaming drains the battery a lot( I only played candy crush and 8 pool) and I did not dare to try graphics heavy games on this. However, one plus point is that the phone charges super fast. Secondly, the OS. It is very smooth. I am using IOS 8 and have found it to be better then the Android experience. The audio is absolutely superb and having used apple ipod nano and iphone 3gs before I knew what I was getting into and the audio is better then anything I have used. The camera is good but not at par with the ones available in phones in the current price range.
Overall I am satisfied with the phone. I do not have any issues regarding the small screen. The screen is very vibrant and provides great visual clarity in sunlight as well. 8 gb internal is enough for me to carry my music and the small number of apps I use. one negative point is that the phone heats a lot, even with a little amount of gaming.
Please do not buy this just because this is a apple phone. this might not satisfy all your requirements. Also there are better options out there in this price range. I got this because this satisfied all my requirements. Lastly the phone looks and feels gorgeous. But that is my personal opinion:)
