Poorly Optimized. Uber does a better job at giving u audio prompts if u use a secondary app for navigation like Waze. Lyft just stays mute. Also, when I use Lyft, my S21 is super hot!!! This doesn't happen with Uber. It has to be the app and the optimization. Just running Lyft slows down a phone that has a Snapdragon 888. Make it Make sense.
