Yeah, I recognize this all too well. There is an implicit assumption that all hardware is top-tier, all phones are flagships, all mobile internet is 5G, everyone has regular access to free WiFi, etc.

Engineers and designers should compile on the latest hardware, but the execution environment should be capped at the 10th percentile compute and connectivity at least one rotating day per week.

Employees should be nudged to rotate between Android and IOS on a monthly or so basis. Gate all the corporate software and ideally some perks (e.g. discounted rides as a ride-share employee) so that you have to experience both platforms.

If they get the latest hardware to build on the build itself will become slow too.
