I switched from the iPhone 5S Gold to the Nexus 5, looked pretty neat so I thought I'd try it out. Turns out, Android still has the same problems it had when I switched from my 4S to the S3, and ultimately ended up with the iPhone 5. Now I'm happily back on my Gold 5S.
True dealbreakers include:
1. Battery- Gotten better, but it still comes nowhere close to what I get on the iPhone
2. Charging Time- iPhone 5 gets a full charge in less than 45 mins, the android phones I've tried take 1.5+ hours to get in the 90s
3. Ease of use- It's true that nothing is as seemless and fluid as iOS, I've tried launchers, stock, and samsung skins. Doesn't come close..
4. Durability- I've got insurance, but still I've dropped plenty of iPhones and never broke any myself. Also dropped a few galaxy's and my friend dropped his nexus, all shattered the first time.
5. iMessage and emoji's- It's actually a HUGE thing for teens users..
6. Camera- The Nexus camera was, well, ****** to be honest. Doesn't even come close to the iPhone. When looking at other phones such as the galaxy, the camera apps are awful. Not as simple and useful as the iPhone. The built in slow motion on the 5S is a bonus, can actually make some really cool ****!
There's probably workarounds for some of these problems, but why waste time doing that when you don't really gain anything as a normal user from android over iOS?
