I'm guessing that you have turned wi-fi and Bluetooth off in Control Center. If that is the case, it has changed how it works. To turn them off completely, you must use the switch in Settings. This is a change by Apple. See this, Use Bluetooth and Wi-Fi in Control Center with iOS 11 - Apple Support
Having Bluetooth and Wi-Fi on will not adversely drain the battery. I keep mine on all the time.

what is the purpose of having it incontrol centre if it does not work as expected. it works for mobile network . if i turn off from control centre in settings also it is switched off. but same does not happen for wifi and bluetooth.
and what is reason that battery is adversely draining compared to before. previously I used to use it whole day from morning 6 til evening 11 and it never got drained. but now it does not even make past noon
why does turning off my alarm in morning turning on my wifi. I use the toggle to switch off wifi in night morning it turns on its own when we stop the alarm whichc is ridiculous. and wifif and. bkuetooth keep turning on it own if we use toggle
