I stumbled over this article:
https://themarkup.org/artificial-intelligence/2025/08/04/california-surveillance-pricing-ban
It claims that companies like e.g. Uber are thinking about charging different prices depending on the battery status of your device (if it's low you are desperate and therefor charged more)
I was wondering it it was technically even possible to prevent an app from requesting the current battery status (GrapheneOS or Android in general)?
