So I want to keep myself more mindful about making my app faster on less powerful devices. I figure a good way to do this is to build my app on devices with lower specs than the usual high end phones but, this is difficult because I like to use Genymotion. Therefore, how can I configure genymotion to run at lower speeds than it normally does?
According to this
you need to
Open VirtualBox and select emulator
Go to setting, then go to system tab
Also it would be better to emulate the slowest device from the genymotion list.
