I have used the iPhone for so many years, but today I found out that it can also be used to weigh

Basic hardware requirements for iPhone weighing

Not all iPhones can weigh objects, but they need to meet some basic conditions.

First of all, the iPhone needs to support 3D Touch hardware, that is, the gravity pressing function. Currently, only models between iPhone6s and iPhone xs max support this function, while the latest iPhone 12 series does not support it.

Secondly, you need a software platform that can measure weight. For this platform, you can use the browser that comes with your iPhone to search for "touchscale".

After an iPhone that supports 3D TOUCH enters this platform, you only need to press the screen with your finger to change the numbers showing the weight.

How to use iPhone to weigh

First, you need to turn on the iPhone's touchscreen function. Open the iPhone's settings, find [Touch], then find the [3D Touch & Haptic Touch] function and turn it on.

Then go to the "touchscale screen electronic scale" website just mentioned, and then place the object to be weighed on the iPhone screen, and the current weight of the object can be displayed in real time.

It should be noted that not all objects can be weighed directly. The 3D Touch function needs to sense the pressure on the screen and the electric field of the human body to work. Therefore, only objects that can be touched can directly display their weight, and other objects need to be weighed with the help of a metal object.

If you are at home, you can place a metal spoon on the iPhone screen and then place the object to be weighed in the spoon.

After comparative testing with an electronic scale, using the iPhone's 3D Touch function to weigh, its accuracy is still very high, and it is exactly the same as the count of the electronic scale.

I have to admire this practical black technology, it is really very convenient to use. However, due to the screen of the mobile phone, it only supports a maximum weighing of 385 grams. ​
