Making phone calls, sending messages, surfing the internet - for most people, everyday life without a smartphone is almost unthinkable. This makes it all the more important to be able to rely on the devices. Which model is the test winner? Which has the best mobile camera or the most powerful battery?...

USB-C, 48-megapixel main camera and AI: Apple has made many small adjustments to the iPhone 15 Plus and given the device some useful improvements. However, it is questionable whether these are reason enough for owners of a previous year's model to buy one.

The iPhone 15 Plus has the longest battery life of all the 15 models. The OLED screen is very bright and nice and large. The 48 MP camera also takes excellent pictures as long as you don't zoom in too much. The Pro models are faster, but the Plus is also stylish. If you switch from Android or older Pro iPhones to the 15 Plus, the 60 Hz judder could be annoying.
