Extend the runtime of your iPhone 15 with this DJ-IPH15 3690mAh High Capacity replacement battery. The original iPhone 15 battery is rated at approximately 3349mAh — this upgraded version delivers over 10% additional capacity for longer daily use. The iPhone 15 was released in 2023 featuring a 6.1-inch Super Retina XDR display, A16 Bionic chip, and supports 20W fast charging (up to 50% charge in 30 minutes). This Li-ion battery is built with grade A cells and multi-layer safety protection against overcharge, over-discharge, and short circuits. CE and RoHS certified for safety compliance.

Important Notes: iPhone 15 has a sealed design with adhesive-secured battery. Professional installation is strongly recommended. After installing a third-party battery, iOS will display a “Non-Genuine Part” notification in Settings. This does NOT affect battery performance or safety — the battery will function normally. The battery health feature may not display accurately with non-Apple batteries. Always check your iPhone model (A2846 for iPhone 15) before ordering.

Compatibility Note: Fits iPhone 15 (A2846) only. Not compatible with iPhone 15 Plus, iPhone 15 Pro, or iPhone 15 Pro Max. The original iPhone supports 20W or higher USB-C fast charging — this replacement maintains the same charging capability. Please verify your device model in Settings > General > About before purchasing.

Battery Care Tips: Avoid full discharge — keep battery level above 20%. Do not expose to high temperatures or direct sunlight. New batteries require 3-5 full charge cycles to reach optimal capacity. For best lifespan, use a 20W or higher certified USB-C charger. If you notice swelling or overheating, stop use immediately.
