We have just implemented 5 tracker, but still app has lot of features where trackers are not implemented.
Does the session length and hence average session length per user, take the time into consideration of a scenario when user is still using the feature( using the app) on which trackers are not yet implemented?

Hi @sanchit 

Technically, the session length gets calculated as shown here.

As long as your session start is tracked from atleast some part of the app, the time spent will be dependent on how the session ends - either it’s based on your timeout interval or the last tracked event from the session. I would recommend playing with “Custom session property” from your project settings and see it the time spent metric differs from the Amplitude defined sessions.
