After updating my Nothing phone (1) to Nothing OS 3.0 and Andorid 15, I expect to have component health as the function that Andorid 15 give, but there is no option on that after updating. So after some research i found the solution how to access.

You will have Battery health and storage health status after this.

Here is my screenshots of Phone (1):



Glad I could help 😀
