My friend Nexus 5 had the same shitty performance in the same timeframe and then I realised that he never used an iphone and for him that sluggish performance was normal and he never noticed that he had a problem. Pretty much every other Nexus 5 that I have seen was the same and my friend Nexus 6n or whatever is called was even slower when it was newer.
