Android System Battery Drain

Zen Master I

Getting a huge battery drain from Android System. Usually the percentage isn't so high & is similar to the Kernel OS. Also, if I'm using an app for longer than usual, it goes above android system in battery usage (as it's being used heavily) however, since last few days android system is eating away at the battery. Anyone having a similar issue on Rog phone 7? Is this normal? Please see screenshot


its misleading because if an app keeps the android system awake then itll show that its android system draining the battery but not the app that keeps the system awake.
