Low power mode on iOS #105

E.g., Something like this if done outside of direct support in TSDK

on phone sleep, disconnect Ziti (disabling identities should be sufficient, assuming disabling attempts to access the controller and ERs causes the majority of battery usage)
on wake, reconnect
Button on UI to enable/disable this mode (presuming since some apps will need connectivity while phone is sleeping

Alt: consider supporting this mode in TSDK (e.g., connect to ERs only on Dial attempt - perceived performance would be impacted, and doesn't address hosting services...)

Also - make sure that "low power mode" requires interceptDnsByMatchingDomains==true to avoid DNS traffic routing through the appex...

Disabling identities on sleep and re-enabling on wake so fair if a big failure. When not in Do-no-disturb, phone sleeps and wakes up very vert frequently, having the opposite of intended effect on the battery.

Need a new strategy: a) only disable if been asleep for some time period (e.g., a couple of mins)? b) only disable if also in Do-not-disturb mode? c) add a setting in TSDK or CSDK that allows a quick "tune down" (dramatically slow down things like service requests and posture checks, anything else running on a timer...)? d) Just setting tunnel networking to nil so no apps using the tunnel can cause traffic? prob not enough. maybe combine with c)?

I was wondering if this can be prioritized again? As of right now the mobile client massively drains the battery, making it impractical to leave it enabled all the time. It would be great if it could get to the level of the WireGuard iOS client, which consumes very little power.

Yes. We have heard from a handful of users that they are having this issue and are discussing potential approaches to address it. When we have something, I'll post it in Discourse and on this issue and solicit users to join a TestFlight.

Wonderful! Looking forward to it.
