Well, I'm an iPhone user again. After a few months of using the Nexus 5, I finally decided to switch back to my iPhone 5.
Don't get me wrong, the Nexus 5 is a fantastic phone, and for the most part I really enjoyed using it. For the price, its hard to beat.
But it definitely wasn't without its issues. In the end, my reasons for switching from the Nexus 5 are these:
1. *The Camera.* The camera on the Nexus 5 is good...but not remotely great. The focus was lethargic, and the overall quality of the image was just not as sharp or color correct as I need it to be. Its probably fine for most people, but for me it was just too slow and too low quality. I was constantly struggling to make things work.
My iPhone 5's camera actually has a tiny defect on the lens....and I still preferred using it.
2. *The Battery*. This became a deal breaker. My Nexus 5 required way too much TLC for my taste. It was like playing one of those memory/puzzle games in Tomb Raider: deactivate this, remove that, set this to that, test...nope, that didn't work....rinse & repeat. I would search for answers in forum after forum...and while everybody was quite cheerful about the fact that a solution existed, the advice was usually "Follow these easy steps 1 thru 68...." I just don't have that kind of time to do what, in my mind, the phone should just do anyway.
By "battery problem", by the way, I mean I would sometimes lose 75% power over night....with the phone just sitting there.
A couple of weeks ago, I remember that I'd let my iPhone 5 drain down to 3% on a monday night. I left it on my side table. That Friday night, that damn thing beeped at me: 1%. Holy cow. That's battery management.
3. *If my iPhone is a cat, my Nexus 5 is a dog.* The Nexus 5 is awesome and fun, but it was also sort of high maintenance. So if my iPhone is a cat, the Nexus 5 would be a dog. Both are great pets...but their personalities and needs are dramatically different. The Nexus 5 is always cute and fun and loves me...but it also falls apart unless I constantly hold its hand and tell it what to do. While my iPhone probably doesn't care if I live or die, and isn't quite as trainable....if I dropped it in the middle of a jungle on the other side of the world, its going to be just fine all on its own.
So ultimately, the iPhone won me back. Not because I'm an "iSheep" or fanboy or too stupid to understand the glory of Android. I liked the Nexus 5, and I love my Nexus 7. But my iPhone just sort of gets me, and gets out of my way.
