Another small suggestion from me. 
I think that users who like statistics would find it really cool if r1 could answer questions about its own technical values.
I’m specifically thinking of questions like:
Question: “How long will your battery last?” Answer: “My battery lasts about 7 hours with current use…”
Question: “How long will it take until the battery is fully charged?” Answer: “My battery is fully charged in about 10 minutes”
Question “What is your technical condition?” Answer: “The health of my battery is still about 96%. My PTT button has already been pressed 2456 times and will last X more times before it simply falls out of the device…” or something similar. (just a joke! 
)
Question: “How good is your connection?” Answer: “I’m currently connected via WiFi and the maximum possible transfer speed is currently X MB’s per second.”
