Buying Guide

Match battery to your exact model

Confirm model compatibility (e.g., iPhone 12 Pro Max, 13 Pro, 14) before purchase to avoid fit or connector mismatches

Prioritize capacity that meets your needs

Higher mAh (e.g., 12000–19900+) increases runtime but may affect fit and heat; balance capacity with device specifications

Look for included repair tool kits

Kits with screwdrivers, pry tools, and adhesive strips simplify installation and reduce the need for extra purchases

Check brand and seller consistency

Choose batteries from sellers with clear part listings and consistent model coverage to improve compatibility confidence

Assess safety and installation guidance

Prefer batteries that provide installation instructions and recommend proper handling to reduce risk during replacement
