My iPhone 8 from 2017 is still going strong, it replaced an iPhone 4 (2011-ish I think) when WhatsApp, the bank’s app, and other important applications stopped working. I guess I’ll have to switch later this year or maybe next since the battery life is getting too short and summers hit it good. I hope they make the iPhone 16 tough cause it has to last me until the put out the 32 to keep on this neat powers of two progression lol.
