Important Battery Information

Safety Precautions Before Installation :

• For your safety, discharge your battery below 25% before disassembling your phone. This reduces the risk of a dangerous thermal event if the battery is accidentally damaged during the repair .

• If your battery is swollen, take appropriate safety measures and handle with extreme caution .

• Google warns that disassembly of the front laser assembly could result in hazardous exposure to invisible infrared laser emissions .

First-Time Use:
For optimal performance, condition your new battery properly:

• New Lithium Ion batteries achieve full performance and longevity after 2 to 3 complete charge and discharge cycles

• After these initial cycles, the battery will be fully conditioned and ready for normal use

• For optimal performance, calibrate your newly installed battery after completing the installation 

Battery Calibration:
For the phone's software to accurately read the new battery's capacity, follow this procedure :

1. After installation, charge the battery to 100% and continue charging for at least 2 more hours

2. Use the device until it shuts off due to low battery

3. Charge it to 100% uninterrupted

4. This helps the phone's software accurately read the new battery's capacity

Storage and Care:

• Do not expose the battery to flame or excessive heat

• Keep the battery dry and avoid immersion in or exposure to water

• Discontinue use immediately if you notice any change in the battery, such as discoloration or deformation

• To maintain battery health, charge when the level drops to 15-25% rather than letting it drain completely to 0%

Proper Disposal:
Lithium-Ion batteries should never be incinerated or thrown into household trash. Always recycle old batteries through R2 or e-Stewards certified recyclers .

Installation Information

This is an advanced-level repair requiring careful attention. The Google Pixel 4 XL features a non-removable battery design, which means professional-grade tools and techniques are necessary for safe removal of the old battery .

Many high-quality battery kits include a complete set of repair tools to assist with the replacement :

• Opening picks and tools

• Spudger

• Suction cup

• T3 Torx screwdrivers

• Adhesive strips

Installation Tips from iFixit :

1. Prepare an iOpener or heat source and apply it to the bottom edge of the back panel for one minute. A hair dryer, heat gun, or hot plate may also be used, but be careful not to overheat the phone—the display and internal battery are both susceptible to heat damage .

2. Apply a suction cup to the heated edge of the back panel by pressing down on it to create suction, as close to the edge as possible .

3. Remove the four T3 Torx screws securing the battery connector shield (one 1.8mm screw, one 4.1mm screw, one 4.4mm shouldered screw, one 4.0mm shouldered screw) .

4. Use the pointed end of a spudger to pry the battery connector straight up from the motherboard to disconnect the battery .

5. The battery is held in place with three separate stretch adhesive strips connected to a single black pull tab. Pull on the black pull tab at a shallow angle with steady force. When the adhesive grows long, roll it around a spudger and continue pulling .

6. If the adhesive pull tabs snap, you can fill a plastic dropper or syringe with high concentration isopropyl alcohol and apply a few drops under the edge of the battery. Give the alcohol a minute to weaken the battery adhesive .

7. Don't insert the opening pick on or anywhere below the grip sensor cable, as the pick can damage the charge port flex cable located underneath the battery .

Important Safety Precautions:

• Professional installation by a qualified technician is strongly recommended

• Never puncture, deform, heat, or throw batteries into fire

• If the battery is swollen, handle with extreme care and avoid applying pressure 

• Use only plastic tools when working near the battery—metal tools can puncture the battery and cause a fire or explosion

• Whenever you use the spudger near the battery, be very careful not to puncture the battery 

• Disconnect the battery before attempting any repair

• Use ESD (electrostatic discharge) protection

• Keep defective batteries away from children and pets immediately

• Properly dispose of old batteries at an authorised electronic waste recycling centre

During reassembly, this is a good point to power on your phone and test all functions before sealing it up. Be sure to power your phone back down completely before you continue working .

THE REPAIR PLUS strongly recommends having this component installed by a qualified technician with experience in smartphone repairs. We are not responsible for any damage caused during installation.
