✅ Why Our Warranty Stands Out

🔋 90-day warranty is the industry standard for replacement batteries. Batteries naturally lose capacity over time — this normal wear is not covered. Warranty applies to manufacturing defects only.

Package include: 1 x battery
Supercharge your iPhone 15 Pro Max with this DJ-IPH15ProMax 4920mAh High Capacity replacement battery. The original iPhone 15 Pro Max battery is rated at 4422mAh — this upgraded version delivers over 11% additional capacity (approx. +500mAh) for extended daily use. The iPhone 15 Pro Max features a 6.7-inch Super Retina XDR display with ProMotion, A17 Pro chip, titanium design, and supports 20W PD2.0 fast charging (up to 50% charge in 30 minutes) [citation:4]. This high-density 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. Designed to exceed the performance of standard aftermarket batteries — delivering the highest available capacity for this model.
⚠️ Important Safety Warning from Apple: For batteries installed with adhesive (including iPhone 15 Pro Max), Apple recommends only installing new batteries. Used battery cells can become damaged during the adhesive removal process, which could cause battery overheating, swelling, venting, leaking, or a battery thermal event. These events could result in fire, injury, death, data loss, or damage to the device [citation:9]. This battery is brand new — do not reuse old batteries. Professional installation is strongly recommended.
Important Notes — iOS Compatibility: iPhone 15 Pro Max has a sealed design with adhesive-secured battery. After installing a third-party battery:

  • iOS 18 or later: After reassembly, run Repair Assistant (Settings → General → About → Parts & Service History → Restart & Complete Repair). This will calibrate the battery and restore Battery Health display functionality [citation:3][citation:6].
  • iOS 17.6 or earlier: You may receive a “Non-Genuine Part” notification and cannot access Battery Health data. The battery functions normally — this is an iOS limitation, not a product defect [citation:6].

Compatibility Note: Fits iPhone 15 Pro Max (A2849, A3105, A3106, A3108) only. Works with all regional models — China (国行), US, Hong Kong, Japan, Europe, and other regions. NOT compatible with iPhone 15, iPhone 15 Plus, or iPhone 15 Pro. The original iPhone supports 20W or higher USB-C PD 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 certified 20W or higher USB-C PD charger. If you notice swelling or overheating, stop use immediately. Apple recommends only installing new batteries — never reuse a battery that has been removed.

Frequently Asked Questions

The DJ-IPH15ProMax high capacity battery is compatible with iPhone 15 Pro Max (models A2849, A3105, A3106, A3108). Works with all regional versions — China (国行), US, Hong Kong, Japan, Europe. This battery is NOT compatible with iPhone 15, iPhone 15 Plus, or iPhone 15 Pro. The original iPhone 15 Pro Max battery capacity is 4422mAh [citation:1] — this DJ-IPH15ProMax replacement offers 4920mAh, over 11% additional capacity (approx. +500mAh). For reference, high-end aftermarket brands offer 4700-4850mAh for this model — this 4920mAh battery provides even higher capacity. Please verify your device model in Settings > General > About before purchasing.

Yes — with important iOS version notes:
- If your iPhone is running iOS 18 or later: After completing the battery replacement, go to Settings → General → About → Parts & Service History, tap "Restart & Complete Repair" to run Repair Assistant. This will calibrate the new battery and restore Battery Health display functionality [citation:3][citation:6].
- If your iPhone is running iOS 17.6 or earlier: iOS will display a "Non-Genuine Part" notification and you will not be able to access Battery Health data. The battery functions normally with full 4920mAh capacity — this is an iOS limitation, not a product defect [citation:6].
For best results, update to iOS 18 or later before or after the repair.

Yes, this DJ-IPH15ProMax 4920mAh high capacity battery fully supports the 20W PD2.0 fast charging capability of the iPhone 15 Pro Max. With a 20W or higher USB-C PD power adapter (sold separately), you can charge from 0% to approximately 50% in around 30 minutes [citation:4]. A full 0-100% charge takes about 90-120 minutes.

Professional installation is STRONGLY recommended for three critical reasons:
(1) iPhone 15 Pro Max uses three strong adhesive strips to secure the battery — removal requires specialized tools and technique [citation:6];
(2) Apple explicitly warns that used battery cells can become damaged during adhesive removal, causing overheating, swelling, leaking, or fire risk [citation:9];
(3) The repair requires a battery press to properly adhere the new battery — improper adhesion can cause battery movement inside the device [citation:3].
If you choose to DIY despite these warnings, watch a full iFixit teardown tutorial, use a heat gun to soften adhesive, keep battery charge below 25% before removal, and never reuse a battery after removal.
