Amount of data transferred to the mobile device

[yashag]

When Accessing a dashboard from a mobile device, does the entire Data set is being downloaded to the phone?

The issue is mainly for people accessing a large dashboard while they are out of the office without wifi connection. It has a serious impact on the amount of time needed to access the data (and also possibly their phone data package cost).

Hi @yashag,

You can take a look at below article about power bi mobile cache data:

View your data offline in the Power BI mobile apps

By default, Power BI refreshes the data frequently so you get up-to-date answers to your business questions any time, even while commuting or roaming.
Data access while you're offline
While you're offline, you can access and interact with dashboards you've accessed previously from the mobile app.
You also have read-only access to any Power BI reports you've accessed previously from the mobile app. You can see the full report, but not filter, cross-filter, sort, or use slicers on it.
Background data refresh
Background refresh updates your favorite dashboards, plus dashboards and reports you've viewed in the last two weeks, with the data on the Power BI service (not the data source). If you're connected to wi-fi, background refresh updates every 2 hours. Otherwise, if you’re on a 3G network, Power BI updates the content every 24 hours.
You can turn off background refresh, for example to avoid network usage. Check the settings on your device.
Note: If you use the Power BI mobile app on an iOS device and your organization has configured Microsoft Intune MAM, then background data refresh is turned off. The next time you enter the app, Power BI refreshes the data from the Power BI service on the web.

Based on the document, when you refresh the report, power bi mobile will auto cache your dataset data until the cache file reached to 250mb.
