Asus 5z Background apps and battery issue.

Background apps are there even after reboot or powering off and switching on the phone. Even if suspend in background switch is on.
Is this right or a bug.
Latest update is draining more battery than the previous. I think there's some problem in the recent update. Needs to be fixed.

Hi, we'd request you follow the below steps:
1. Clear system cache.
2. Try the same under safe mode:
Hold the power button for 5 seconds => When the screen flashes with option => Press & hold power option => You will get an option to restart in safe mode
3. If still you face the issue factory reset your phone after taking a full backup.
Please follow below steps may improve battery backup:
1. Close apps that are not used (Bluetooth, WiFi, GPS, etc.)
2. Adjust sleep time and brightness (Settings > Display)
3. Boost memory when you see memory consumption is high with no app running,
4. check for background running applications, stop/disable unwanted apps, you can manage apps from auto-start manager.
Hi, I correct a point Background apps means which I have opened recently and running. Even after a restart they're running and also in safe mode they appear.
Is this normal.
