 What is the power management feature of Android?

Power management is another important feature of Android. The Android devices have to be managed to keep the power consumption to a minimum since it is generally battery-powered.


How do android phones save power and increase battery life?

Apps consume power as memory management i.e. RAM is involved. In order to keep battery consumption to minimum the app is suspended in memory when it is not in use. So, the app though technically open does not consume any resources and sits idly in the background till needed again. Also this makes it easier to improve the responsiveness as the apps don’t need to be reopened each time


How do android phones manage apps to save memory?

The management of apps stored in memory also takes place automatically. When memory is low, Android kills the apps and processes which have stayed inactive for sometime in the reverse order of its usage. This saves the user of trouble to manage memory and kill the apps themselves often.


 What is the relationship between device hardware and Android version?

The hardware features depend on the versions of Android to a certain extent. The current versions of Android require at least 512 MB of RAM and a 32 bit ARMv7, MIPS or x86 processor with a compatible graphics processing unit.
