so i got my Iphone 8 Plus on May 2018 and about a month later i started noticing that my battery is draining while not in use. For example when i go to sleep and wake up the next morning there is 30% less battery than the night before(90% - 61%). Both wifi and bluetooth Are off and none application Is in use. Why is this happening? What can i do?

Understood... It is about options
Do Not Disturb options—
at a certain time, you can set a schedule. Tap Settings > Do Not Disturb and turn on Scheduled. Then set a time.
You can also choose when you want to receive alerts, calls, and notifications:
Use Do Not Disturb on your iPhone, iPad, and iPod touch - Apple Support
With any smartphone there is no such thing as "not in use." As long as it is turned on there are things happening. Arriving email, texts, weather, stocks, and other updates. Registering with the cellular network every few minutes so it can find you when you get a call. You can see what is using the most energy by going to Settings/Battery. It will list the heaviest users of energy.
A best practice is to charge the phone overnight, every night. This uses the mains current instead of the battery once the battery is fully charged. And it the phone is also connected to Wi-Fi and locked (and the feature is turned on) it will back up to iCloud every night, ensuring that you can never lose more than 1 day's worth of content.
User troubleshooting is:
Follow the 3R's- if a restart does not solve your problem proceed
1. restart, ie power off/on,
2. reset http://support.apple.com/kb/HT1430,
3. restore from backup, restore as new device. http://support.apple.com/kb/HT1414
Charging it overnight means that it will always have a full charge in the morning, which should get you through the day. And you get the benefit of the automatic backup. You should not shut it down to charge it, if that's what you were thinking.

If you are one of these users, in Settings App, tap your Apple ID, then tap iCloud, then find iCloud backup and turn off iCloud backup and only turn this on to do daily backups either when you are not using your iPhone for a prolonged period of time (like when you are sleeping), then turn iCloud backups OFF when actually using your iPhone.
This is bad advice. If it's only a minority doing this that is very unfortunate, as some day they will forget to back up and the howl about how they lost all their photos and other data. EVERYONE should leave iCloud Backups on all the time.
If you turn on iCloud Backups it only backs up once a day, and only when the phone is plugged in, connected to Wi-Fi and the screen is locked. So it does not put any load on the battery; it actually backs up while the phone is charging and otherwise idle, and will have no effect on battery life. It's a best practice to leave it on all the time, and leave the phone plugged in to a power source overnight. See: How to back up your iPhone, iPad, and iPod touch - Apple Support, the section Automatically Back up with iCloud Backup.
I agree with everything else you covered
I am trying to charge it overnight but most if the times it’s not necessary .the battery is over than 40% when i go to sleep and i prefer not to shut it down because of calls i might get. But when i wake up i find it either with less battery than the night before or complete dead.
No i get it. I charge my phone only when the battery is about to die. thats why i said that sometimes I cant charge it overnight because the battery percentage is over 40. I know that i can charge it overnight and still have it open. But isn’t better for the battery to charge it only when its about to die?

DEFINITELY NOT. While it won't do any immediate harm, continually letting the battery get to zero or near-zero will shorten its life. Lithium battery technology is nothing like older technologies such as NiCd. Lithium batteries have no "memory effect." And if they go completely flat they die, immediately. Apple takes this into account; when the phone shuts off at zero there is still some capacity left, specifically to prevent it from going flat. But if you leave it uncharged for a week or more it will go flat, and you may have to replace it. The phone also protects the battery from overcharging; when it reaches 100% the charging circuit (which is in the phone) stops charging completely.
You can charge the battery whenever convenient, regardless of the current state of charge, and you can remove it from charging at any convenient time. So you can charge it when it's at 40%, and disconnect it at 80% if that fits your lifestyle.
How much free data storage space is left on your iPhone?
iDevices need to always maintain, at the very least, between 2-3 GBs, OR GREATER, of free data storage space.
In Settings app, under General settings, Reset panel, at the right bottom of the list, Reset All Settings.
In Settings App, Battery, check to see if any apps/processes are eating up your battery.
In Settings App, General,Reset, Reset Network Settings, try resetting your network settings.
Try re-adjusting your iPhone’s screen brightness to a lower, but still comfortable intensity.
In Settings app, General settings panel, turn OFF Background App Refresh for any apps you feel do not need constant data updating/Internet updating in the background when not using the an app OR turn OFF Background App Refresh entirely/globally for the entire device.
Do the same in the Settings app under Notifications.Turn off notifications for apps you do not think you need notifications for and/or edit the different ways you receive notifications to help with performance by not always using all the notification methods together.
In Settings app under Mail, you may want to set a longer fetch time or set your iOS Mail app to only manually fetch your mail ONLY when you launch the iOS Mail app.
Some minority of user have been turning ON and leaving ON iCloud backups continuously backing up on a constant and daily basis.
If you are one of these users, in Settings App, tap your Apple ID, then tap iCloud, then find iCloud backup and turn off iCloud backup and only turn this on to do daily backups either when you are not using your iPhone for a prolonged period of time (like when you are sleeping), then turn iCloud backups OFF when actually using your iPhone.
OR
Only perform your backups on a lesser time schedule.( like twice a week, once a week, once every two weeks, once a month, etc.).
Any large amount of background running apps or active processes that have to constantly go out to the Web to fetch data ALL THE TIME is going to slow down ANY iDevice and can, also, negatively impact battery life.
Good Luck to You!
They are misinformed. iCloud backup does not incrementally back up all day long. It's backups are incremental, meaning it does not do a complete backup but only content that has changed, but it's still only once a day and only when the phone is connected to power, Wi-Fi, and locked.
Some people confuse iCloud Backups with iCloud sync. They are completely separate. If you turn on the switches in iCloud Settings the items that are on will sync in real time. So if you add a contact on your iPhone it will appear within seconds on your iPad, your Mac, iCloud for Windows and web icloud access (icloud.com). Likewise for all of the other switch options, including photos. You can restrict these sync operations to Wi-Fi only if you want to, but either way it won't affect battery life measurably.
I’ll try this ,Thank you:)
Do not disturb will cut down on some battery usage
AirPlane mode will cut down on even more
if these are possible options...
It won't receive calls in airplane mode, however.
I had tried that but it still darins battery.
There is 50GB free space in my iphone. I’ll try all those thank you very much.
