If used improperly, the smartphone battery may catch fire and cause a fire or injury to the owner. To prevent this from happening, Xiaomi has patented a technology that can analyze the state of the battery. This is intended to enable the user to be aware of the potential hazard in advance.
Old lithium-ion batteries are explosive: they swell and deform your smartphone. Back in 2017, Xiaomi applied for a patent registering a technology capable of alerting the user to deteriorating battery performance. The approval was received on February 9, 2021.
According to the document, a piezoelectric circuit can be placed inside a smartphone that can determine the expansion of the battery. The technology is based on the detection of a current signal indicating that the acceptable battery thickness exceeds a threshold.
This means that the user will be able to replace the battery in a timely manner, thus preventing damage to the smartphone and other dangerous consequences. There is no exact information yet on whether Xiaomi plans to integrate such technology into its gadgets in the future.
