Hibernate app is for both Rooted & Non-Rooted Users who want to improve their poor battery life. Hibernation is a state of inactivity that is characterized by low device temperature, slow processor execution & by disabling the execution of battery draining apps.
It disables and locks the execution of battery draining apps to make them in deep sleep mode. However, the hibernation of apps is only effective when the screen is turned OFF.
Whenever the CPU is running with full speed, the phone becomes hot. Full speed means high clock speed & high frequency of CPU. Suppose your android phone has 1.9 GHz Octa-Core Processor, Hibernating CPU will limit the CPU frequency up to 500 MHz and it will uses 4 Cores instead of 8. So, this techniques lowers CPU temperature & saves battery consumption.
You can even Hibernate Settings like WIFI, Bluetooth, Data Connection & Sync. Its like whenever you turn OFF the screen, WiFi becomes OFF & whenever you turn ON the screen, WiFi starts automatically. The same thing applies to Data Connection, Bluetooth & Sync also.
