Product Overview

Say hello to uninterrupted days and goodbye to battery anxiety. The Peace-of-Mind 3.857V 3349mAh Lithium-Ion Battery Replacement is engineered specifically for the iPhone 15, delivering superior energy capacity, enhanced safety protocols, and seamless integration with Apple’s intelligent power management system. With a higher-than-original voltage design (3.857V) and an upgraded 3349mAh capacity, this premium replacement battery doesn’t just restore — it elevates your iPhone 15’s performance.

Unlike generic batteries that degrade quickly or fail compatibility checks, our lithium-ion cell is built using Grade A+ polymer technology, ensuring stable voltage delivery, reduced heat generation, and up to 500 full charge cycles without significant capacity loss.

Whether you're upgrading from a worn-out original battery or preparing your device for long-term daily use, this replacement offers real-world endurance that matches modern lifestyles — from morning commutes to late-night streaming.
