Buying Guide

Confirm exact iPhone model fit

Replacement batteries are model-specific—verify compatibility with iPhone 13 Pro, 13 Pro Max or 12 Pro Max to ensure correct connectors and fit

Prioritize higher capacity for longer travel

Higher mAh ratings (13,000–19,900 mAh in our list) deliver more backup power between charges, useful for multi-day trips or heavy use

Value tool kits when DIY installation

Batteries that include a tool kit (several entries include tools) save you a trip to a repair shop and reduce installation risk when replacing the cell yourself

Balance price against verified ratings

Compare cost and user rating—options range from about $33 to $45 with ratings near 4.1–4.3★ to find the for your needs

Check warranty and return policy before buying
