Hi, I've created some Custom Recovery flashable scripts for Moto G, that will remove around 100mb of pre-installed apps and services. Performance and battery-life should improve on your device with the reduced number of services running. I don't own a Moto E but the script should work as intended; I expect many of the same apps are present on your handset. All Motorola and Google apps can be reinstalled via Google Play Store.
XDA Developers was founded by developers, for developers. It is now a valuable resource for people who want to make the most of their mobile devices, from customizing the look and feel to adding new functionality. Are you a developer?
