Hi everyone, this is my first post here so please be gentle 
I currently have an iPhone 6 and am looking to upgrade. I'm definitely after a larger screen but don't want to fork out for an X.
I'm tempted with a pre-owned 7+ from O2 (I'm in the UK) which I can get on a tariff that I'm happy with. My dilemma is that I'm not likely to upgrade for a couple of years and I wonder whether this model will really start to age in the next 24 months? Will iOS upgrades start having a detrimental affect on the phone e.g. on battery life?
Or would I be better biting the bullet and accept paying for a higher tariff for a handset that's one generation younger?
What would you guys do? Thanks in advance!
