Question from the user: “I feel that the iPhone 12’s battery drains more quickly now that the screen has been changed. Is there a screen issue?
Indeed, it might have something to do with the screen you’re using. Poor power consumption management may be an issue with subpar third-party displays. They could keep using power even while in standby mode, which would shorten battery life. Additionally, it is feasible: The screen in use warms up significantly due to improperly calibrated screen data, which causes the system to consume more power to regulate the temperature. The system kept activating due to an unintentional touch phenomena in the background.

Recommended:It is advised to swap it out for a top-notch original factory screen and have it properly calibrated during maintenance, if circumstances allow. Further examination of the battery or system state may be necessary if the issue continues.
