While I'd normally agree with that as I usually focus more on software than hardware, I had the 6 and it was extremely slow - could be due to that battery saving mechanism though. I upgraded to the 7 and it was miles ahead in that regard.
Depends on ones usage but normally 2/3 years. Thats when app developers stop supporting updates for older versions of iOS. For some that might just mean you have to put up with the old version of an app. For other apps they no longer work and are forced into upgrading a device. I don’t think any can complain about a device thats still very capable in its fifth year. It’s hardly a repeat of the iPhone 4 when iOS 7 came out and made using that phone torture.
I haven't checked the details with this one but the term Refurbished is much over used now in relation to phones. It seems to mean so many things, from looking/being almost new (eg O2, Apple direct) to being thrown in a plain box and little else (aka Used, as it was known in the past :D ).
There are general improvements across the board with the 8 and I like the idea of wireless charging. Fair enough that doesn’t float your boat. What would say though is that is not a massive difference in price in the second and market and if you spend the extra front on the eight, it will obviously be worth more when you come to sell it How usable are iPhones once they are out of support? Obviously they don’t stop working, but I wonder if they quickly become redundant because everything is out of date?
100% it has a year, left 3 max if you don’t care about future software upgrades. Personally I’d go for the 7 over the 8. The 8 is just not that compelling to me. Next year I’ll upgrade. See what new phone apple bring out. If it’s as underwhelming as the XS I’ll buy a used X. Hoping for a big camera upgrade.
