With the significant increase in the performance of smart phones, batteries have become their biggest shortcomings, and the major manufacturers' intelligence has extended their standby time through software optimization and the use of newer screen-saving technologies, such as adopting more power-efficient OLED screens, etc. However, the actual improvement is relatively limited. Recently, a company called Arman launched an OLED screen with a built-in solar charging module that allows the phone to be charged at any time.
OLED screens with solar charging capability are expected to solve the problem of short battery life.
The average charging efficiency of the solar charging system is about 11%, and the maximum charging efficiency is 18%. However, Arman currently only has 3.7-inch screen products. I believe that other sizes will be introduced in the future. Although we do not know how it actually works, we can at least give all major mobile phone manufacturers a solution to their weaker battery life.
