🔋 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.

Rated voltage: 3.80V
Charge limit voltage: 4.30V

Extend the runtime of your iPhone XS Max with this DJ-IPHXSMax 3750mAh high capacity replacement battery. The factory iPhone XS Max battery is rated at 3174mAh — this upgraded version delivers over 18% additional capacity for significantly extended daily use. The iPhone XS Max features a 6.5-inch Super Retina display, A12 Bionic chip, and supports 18W PD fast charging. This high-density Li-ion Polymer battery is built with grade A cells and multi-layer safety protection against overcharge, over-discharge, and short circuits. CE, RoHS, and UN38.3 certified. Designed to exceed the performance of standard aftermarket batteries — delivering higher capacity than the factory battery.
Why Choose the High Capacity Edition: The iPhone XS Max originally shipped with a 3174mAh battery. After years of daily charging cycles, the original battery capacity degrades significantly — often dropping to 70-80% of its original capacity. Common symptoms include: the phone requiring multiple charges per day, unexpected shutdowns at 15-25% battery remaining, slower performance due to power management throttling, or visible battery swelling. This 3750mAh replacement battery not only restores the original performance but actually exceeds it with an extra 576mAh capacity. This means longer screen-on time, more hours of video playback, and extended gaming sessions between charges. The battery fully supports the 18W PD fast charging capability of the iPhone XS Max, reaching approximately 50% charge in 30 minutes with a compatible USB-C PD adapter.
Important iOS Repair Assistant Notes: iPhone XS Max has a sealed design with adhesive-secured battery. Professional installation is strongly recommended. After installing this battery: • If your iPhone is running iOS 18 or later: After reassembly, go to Settings → General → About → Parts & Service History, tap “Restart & Complete Repair” to run Repair Assistant. This will calibrate the battery. • If your iPhone is running iOS 17.6 or earlier: You may receive a “Non-Genuine Part” notification and cannot access Battery Health data. The battery functions normally with full 3750mAh capacity — this is an iOS limitation, not a product defect. Updating to iOS 18 or later is recommended for full battery health functionality.
Compatibility Note: Fits iPhone XS Max only. Works with all regional models — US, Japan, Europe, Hong Kong, and other regions. NOT compatible with iPhone XS or iPhone XR. Please verify your device model before purchasing — A1921, A2102, A2103, or A2104 printed on the back of your phone.
