I've been a faithful iPhone user pretty much since the iPhone came out. Never really experienced Android. A co worker just got an LG G2. It's an older device but he said it still holds up to today's devices. I was playing with it yesterday and I have to say I was extremely impressed. Very smooth. The battery is 3000mAH. Not that I'm tired of iOS I'm thinking it might be time for a change.
Has any faithful iOS users have switched and never came back? What has been your experience with Android?
Ex-LG G2 user here. After having used pretty much most of Android's "flagship" models (Samsung Note 3, HTC One M7 & M8, LG G2, LG G3, back to LG G2) I can say that I would never "stick" to Android for an extended period of time.
After my 3GS, I moved to a Iphone 4. Then I decided to return to Android, and tried just about every flagship model for a few months. The BEST I ever tried was the LG G2 (to the point that I upgraded to the LG G3, and found that it just wasn't an improvement, so I moved back to the LG G2) and even though it's a 2013 flagship model, it still is pretty amazing, for Android's standards. The only real issue is the constant hiss you can hear from the headphone jack, which depending on what kind of music you listen to, it can be slightly disturbing. Apart from that, the screen is excellent.
I moved to a different city recently where I'd be commuting to work via Underground, so no more Google Music streaming for me (had over 120GB of lossless music there that I had uploaded). So I now needed a phone with a MicroSD card slot that would support a 128GB MicroSD. I decided to try the Iphone 6 128gb just in case, and boy, was I surprised. Smoothness in all apps, very nice weight and comfy in my pocket. Plus, I can't stress enough how WELL apps work in iOS compared to Android, where the market is so spec-fragmented, that every single app is a bit of a lottery, and you never know if it'll work properly on your Android phone or not.
Plus, every time Android updates, they tend to put in features that NO ONE wants. Like on the G2, they upgraded to Lollipop, and suddenly the notification LED brightness has been reduced to 50%, battery drains faster, some apps crash, and you can't use "Silent mode" if you want to set a wake-up alarm, because it won't even go off with sound...
You know what they say, "the grass is always greener on the other side"... for the initial period anyway.
