You can enjoy up to 7 hours of talk time or almost 12 days in standby mode, so you don't have to worry about running out of battery while travelling. The included USB-C fast charger ensures that you can charge quickly and be up and running again in no time. The TU550 is conveniently smaller than many other phones. Nevertheless, the intuitive icons on the large 2.8-inch colour screen and the central tactile menu key allow quick access to important functions such as text and camera. If you want to take a quick snapshot, simply take a picture with the TU550's integrated camera. You can even share these images by inserting them into text messages. It's important that you can take notes during a call or share them with someone else. The TU550's built-in speaker and special microphone make this possible.
