How to fix battery drain issues on iPhone 16 Pro Max?

I have bought my iPhone 16pro max trading in my 13 pro max. Worst decision I ever made in my life. 

battery is draining so fast, never had to charge my phone twice in a day with a limited use. Didn’t take picture, didn’t call and didn’t use maps or staff like that. 

anyone facing the same problem?

After you first setup your iPhone, your iPhone must work extra hard to run additional background tasks. Some of these include indexing which is sorting all your data on the new device and moving features to the right places. Which you can experience an increased battery drain. When the tasks are fully complete, which usually takes a few days to a week, your iPhone will return to normal conditions.
