I purchased my iPhone in October and till now it has had various problems: 1. Touch ID not working sometimes 2. Battery drainage (REALLY FAST) 3. Loose power, home and volume buttons (out of the box) 4. Incorrect compass readings 5. Safari/other applications crashes Could I get a replacement iPhone? It is still under warranty but I am worried in case it gets refused for replacement, should I take it to the apple store? And what exactly does a Apple warranty cover?
