Hey there,

what is the iOS version is running now?

and what is the battery health of your iPhone?

settings > battery battery health.

See this article ☞ If your iPhone, iPad, or iPod touch gets too hot or too cold - Apple Support

It is assumed that an update has solved the battery drain problem. If you are still facing this problem, you should Contact Apple support!

But before you do that go to Settings > Battery > battery using by app , Check out the applications that consume the battery heavily. If there is nothing that consumes the battery heavily, there may be a technical problem Or if you replace the battery by a store that is not approved by Apple, it may be non-native and may cause the battery to drain.
