Just wanted to see if I should reconsider this purchase. I recently got a brand new iphone 11 from Apple to replace my mother’s iphone 6. At this price point ($500) I couldn‘t find anything used that’s newer. I also had some bad experiences in the past buying used online so wanted her to have a good phone with a good battery and perfect screen. She wanted the larger screen so that she can see it better, so the SE smaller screen wasn’t an option. How many years of updates are still left for the iPhone 11? Hoping for at least 5 more. Wondering if I made a mistake buying this two year old phone.
