Does Android have a different behavior for WakeLock when the device is connected to power source? -

-

to give context: trying measure energy consumption of best practices in android apps. have refactored app using wakelock keep screen on , use flag flag_keep_screen_on instead. surprisingly, able have small improvement on energy consumption.

i expecting cpu able go low power state, spend less energy.

is there different behavior cpu power management in these conditions, or use of flag not expected have reasonable effect?

i measuring device odroid-xu has connected power. android version 4.2.2 - api level 17.

the reason didn't find difference

wakelock prevents device going sleep when device's screen off, while when using flag_keep_screen_on display using power along app, , believe me takes reasonable amount of power.

so result same, while using flag_keep_screen_on might result in bad ux.
