iPhone Battery Replacement Guide - Hands-on with REPART

Typically, iPhones are cycled 500-600 times, and their battery life varies depending on usage habits.

As your iPhone's battery gradually wears down, you may experience more frequent recharging, unexpected shutdowns, and a decrease in overall performance.

Apple recommends replacing your battery when iOS shows that battery performance is below 80%.

In this comprehensive guide, we'll use the iPhone 11 Pro Max as an example to walk you through the exact steps of replacing your battery with a high-quality REPART battery.

Step-by-step Guide

Step 1: Check Battery Health First, navigate to your phone's settings and locate "Battery Health" to assess your battery's condition. If your battery health is low, it's time for a replacement. Before proceeding, long-press the power button to turn off your phone.

Step 2: Detach and Remove the Screen

• Unscrew the bottom screws using a pentalobe screwdriver, ensuring you keep track of them.
• Use a heating pad at approximately 90°C to soften the screen edge glue for 2-3 minutes.
• Secure the screen in place with a clamp, and use suction cups to gently separate the screen from the phone.
• Carefully lift the screen and disconnect the battery.

Step 3: Remove the Old Battery and Adhesive Residue

• Unscrew the battery protection
• Gently disconnect the battery and remove the battery protection ironshield.
• Use tweezers and a littlealcohol to remove the battery adhesive residue.

Step 4: Install the REPART Battery

• Take out the new REPART battery and remove the protective film from the adhesive.
• Attach the adhesive to the battery and press firmly.
• Install the new battery, connect well with the battery connector 
• Reassemble the charging port and fix the shielding plate 
• Reassemble the screen, ensuring all connectors are secure.

Step 5: Power On and Test the Battery Function

• Turn onthe phone and perform battery-related tests, including wired and wireless charging.
• As we preserved the original waterproof adhesive during screen removal, there's no need to install additional waterproof adhesive.
