Iphone 11 pro battery

I am from India and I have been using iPhone 11 pro for the last 2 years have seen that the battery degrades faster than other models. I have seen a youtube video it said that there was some problem with this model and free battery replacements were offered at that time. I missed that chance and now want a battery replacement. My usage is very less and I take full care of my phone. I have disabled background app refresh, disabled all useless notifications, reduced the location accessibility to apps, and other tips to save battery.

Apple, please help me to get a free battery replacement.
