Why my iPhone strong is almost strong i only use it a bit?

Hey Sao_Rithina,

We see you have concerns about your iPhone storage. From the screenshot, System Data is using majority of the storage. System/Other data includes "Non-removable mobile assets, like Siri voices, fonts, dictionaries, non-removable logs and caches, Spotlight index, and system data, such as Keychain and CloudKit Database. Cached files can't be deleted by the system.": How to check the storage on your iPhone, iPad, and iPod touch

Also, the screenshot shows some recommendations to help with iPhone storage. We suggest reviewing those options to see if they interest you.

Take care.
