iPhone 12 battery drain

Hi all,

I have got my new iPhone 12 recently and since from the start, I am having issues with the battery performance as my friend who has a year old iPhone Xr is getting 4-5 hrs. SOT and I am getting just 4-4.5 hrs. SOT with maximum battery capacity 100%.

I have already talked to the apple care people and they asked me to visit the service center and they checked my device for 48 hrs. and provided the feedback that everything is fine. But its been more than 2 months and still I am facing this battery drain issue.

and when I check on many blogs and YouTube videos I see that everyone is getting 6+ hrs. (Even while using camera for most of the time) of SOT and this is the main concern

So, I just want to check if its only me or other people are also getting the same battery performance issues?

Note: I don't game in my iPhone
