·And you can see It turns out that when comparing weighing with an iPhone and a professional electronic scale, the error is very small, which shows how powerful this function is.

In fact, it is an old topic that the iPhone can be weighed, and many mobile phones that support pressure sensitivity can do this. Taking the iPhone as an example, 3DTouch can distinguish heavy pressure or light tap operations on the screen, and can also detect the amount of pressure. This is because capacitive touch screens have the ability to sense pressure.

·However, the capacitive touch screen requires an electric field on the surface to work, so we cannot play with the phone happily if we wear gloves in winter, and clicking on the screen with plastic and other objects will not be effective, so it cannot be weighed. Plastic and other items.

·In order to weigh the iPhone, an electric field is required on the surface of the screen. Therefore, an object that can conduct capacitance needs to be placed on the screen for weighing. Usually, a metal spoon can be placed and the gross weight can be removed in the settings. That's it.

Real experience of iPhone I can operate it with one hand because I have used oppor11s before which are longer but not as thick and the weight is acceptable.

As for the battery life, people say that the battery life of the XR is great. I don’t have any special feelings about this. I just charge it once a day and that’s about it!
