The iPhone 13 mini has no replacement, but considering that not much has changed between generations and that it has just been reduced in price, it still perfectly serves the same target market. Software upgrades for iPhones often last for more than five years, keeping entry-level purchasers and those who just want a tiny phone because they're used to previous phones happy.
Phone 14, iPhone 14 Plus: What's new?
Manufacturers of smartphones are reaching a stage where there isn't much they can do to keep their products seeming new and interesting. The iPhone 14 is a respectable incremental improvement over the iPhone 13, but it doesn't accomplish anything revolutionary or inspire a surge in sales. The iPhone 14 Plus, on the other hand, is a completely new offering, so if you can afford it, you might be tempted to upgrade.
The fact that the iPhone 14 Plus weighs 203g as opposed to 240g, which is significantly less than the iPhone 14 Pro Max, is for me the most enticing feature of the device. This new alternative would be a welcome compromise if the size and awkwardness of the flagship versions turned you off. The iPhone 14 is still one of the lightest devices in its class and is simple to use.
The iPhone 14 Plus offers the longest battery life of any iPhone ever, which is another intriguing feature. Because of its less demanding display and other technology, it can do better in this area than its pricier brothers.
