This app has prevented me from trashing my slow phone. Always got System UI crashing due to low RAM, but after using Greenify, every time my phone slows, I hit power and it refreshes completely. Absolutely essential app.

Great battery saver that really works. Hibernation of background apps makes a noticeable difference in performance and battery life. Some configuration needed but worth the effort for older phones.
