I got the iPhone 11 Pro Max about a week ago ( December 23) and it seems that I’m experiencing battery drain issue

I unplugged it at 10:30am with 100% and now it’s 1:20pm and it’s at 77% with minimum usage ( sent a few photos , texted family and friends , played music for about 20minutes, had a 30second phone call , from 11:30 till 12:30 I wasn’t using it.)

I did a dfu restore , reset all settings , erased all contents. No luck

My battery health is at 100% and I’m not a heavy user. I turned off location services , background app refresh , raised to wake , used mostly WiFi ( avoided 4g) and still my battery can barely last me the day.

My friend also has the IPhone 11 Pro Max and he unplugged his phone at 1pm with 82% on 4g and been using it non-stop and at 5pm he’s at 77%.

Am I experiencing battery drain issue?
My concern is that I won’t able to replace it because if Apple run a test on my battery and see it’s at 100% then they will brush it off and tell me nothing is wrong.

I have provided photos of my battery life from today and the last week.

Welcome to iMore. If it were me regardless if my battery health registered 100% but my drainage was unusual, I would still take it to Apple.
