Various tests and sources including Android sites confirm that the iPhone 5 has a very solid build and high quality electronics. It consistently outperforms the competing popular phone the Samsung Galaxy SIII. See these three videos that specifically focus on macro photography, drop and water damage tests.
Why do drop tests matter? It’s not only because you want to avoid spending extra money replacing or fixing your broken phone. It is also about reducing environmental footprint. Apple is taking the right direction here. We need longer lasting and more durable products that do not need to be replaced every year or so. Good work Apple.
