Some additional information worth noting with this Adidas smart soccer ball is that you cannot use the sensor features for kicks once the ball is in motion. Users report you cannot use it for tracking stats associated with, for example, a drop kick. The ball must be sitting still on the ground before being kicked if you wish to track the statistics.

Why do I always have to pump up even expensive balls? Many balls use bladders made out of latex. Natural Latex Rubber bladders offer the softest feel and response, but do not provide the best air retention. Micro pores slowly let air escape. Balls with natural rubber bladders need to be re-inflated more often than balls with butyl bladders. Even after one or two days, the latex bladder will leak enough air so that you will have to inflate the ball back to recommended pressure. Some balls use carbon-latex bladders in which the carbon powder helps to close the micro pores. Soccer balls with carbon latex bladders usually increase air retention to approximately one week. Of course, check the ball for punctures that may cause the air to leak out.
During the 1900s, footballs were made out of rubber and leather which was perfect for bouncing and kicking the ball; however, when heading the football (hitting it with the player's head) it was usually painful. This problem was most probably due to water absorption of the leather from rain, which caused a considerable increase in weight, causing head or neck injury. By around 2017, this had also been associated with dementia in former players.[8][9] Another problem of early footballs was that they deteriorated quickly, as the leather used in manufacturing the footballs varied in thickness and in quality.[6]
Whereas plenty of manufacturers that we reviewed opted to go with a soccer ball that was more durable than responsive, Mikasa takes the opposite approach and focuses primarily on the touch that their ball can provide. This is most apparent in the soccer ball’s choice of casing material. The synthetic leather casing of the Mikasa is by far the softest and naturally responsive-without the inclusion of texture-out of any other soccer ball we reviewed. https://www.youtube.com/watch?v=3OKagE2ZIRA
