iPhone 6s obsolescence ?
I went into my local Apple shop today, to get the battery replaced in my iPhone 6s. The staff I talked to told me that at £69, and because this model will no longer be supported or receive updates, it does not make sense to spend the money. Now I know shops will always try to upsell, I wasn't born yesterday, but what does this mean for the future of my phone. Will it just stop working, become glitchy, temperamental, or what? Our household has 2 of these and a 7, all of which are now potentially in need of replacement, at no insignificant cost. I am told that all 6s,7s, and 8s are now no longer supported. Any advice would be appreciated.
iPhone 6s, iOS 15
