I had very bad experience with iphone 5s not because its a bad mobile but because of the battery life and the documentation features. I used to travel a lot but the battery life of this mobile is not worth it and also the there music feature and the file transfer system were too much.
You have to pay for every single nonsense app. Official apps always need internet to work. It was so irritating but one thing is for sure buyback of the mobile is much higher than others.
