Hello, people!
I've been using GrapheneOS for a couple of weeks. I can see the battery melting, although the software costs significantly less compared to my stock.
In 1 hour and 6 minutes, from 100% to 81%
The brightness is usually below average. GPS is disabled, I'm mostly on wi-fi. The expense is even higher through the mobile operator. For 4 hours of the screen from 100% to 30% (from 45% the energy-saving mode is activated)
