Iphone 11 Pro Max battery drain after ios update

Question

My main reason for buying the 11 pro max was battery and camera.

I was very pleased with both untill i updated to the latest ios a couple of days ago.

The the phone startet to rapidly drain battery.

Before i could manage two days on one charge. But now i have to charge every day.

Last night i had 100% charge at 23:30. This morning it was down to 70% just overnight with no usage.

Aps like siri and mail use silly battery!

I have tried to contact apple support, but no help. They just tell me to use battery saving mode and uninstall apps i dont use.

I have done the battery calibration by pushing volum up and down + side button. No effect.

I have also tunred the phone on and off.

This is an expensive phone and battery capacity was one of the main selling points for me.

But if there is no fix to this problem i dont see the piont of buying this phone.

Has anyone had similar problems and managed to fix it?

Try some of these options too.

Avoid Screen Mirroring
Put on Low Power Mode
Put Auto Lock On (1 min):- with low power mode it will be 30 Sec
Put Auto Answer Off
Disable Push notifications for apps you do not use often
Enable Auto Brightness:- Settings > General > Accessibility > Display Accommodations > Auto-Brightness [Enable]
Manually lower brightness from Control Center
If you Want to watch continuous Video. Stream it on TV or a Monitor
Don't force close apps; Apps which are not on frontend screen are paused by the system to save energy. Apps require more energy to re-launch. Apps which are open in the background use large memory is a myth and quitting them is counterproductive
Location services to be allowed only while using the app
Set your iPhone to fetch email and calendar data from internet less frequently
Turning off Background App Refresh
Charge before it drops below 20-30%
Try connecting to trusted Wifi where ever available in stead of Cellular
Enable Airplane mode in areas with bad cellular and wifi coverage. Your phone keeps trying for reconnection with the missing / weak network. This uses lot of energy
Switch off Wifi & Bluetooth while in Roaming or Not in Range
Enable "Wifi Assist" : Settings > Cellular or Settings > Mobile Data > Wi-Fi Assist [Enable]
Periodically Check your Battery Health (Settings > Battery > Battery Health)
