I also abused an iphone 5s for years until an upgrade to an iphone 7 earlier this year. Seems like a pretty stable device.
I don't see these problems. Now I'm stuck with a thinkpad at work that has garbage battery life and an infuriating track pad. Every Android phone also turned out to be a turd (Galaxy S3, Moto X). Now that I have a file browser on iOS I don't think I'll ever go back- especially when you consider that Apple is basically the only company in the big 5 that at least publicly goes to bat for your privacy.
