Important Battery Information

Battery Care and Conditioning :

Initial Charge:

• The battery should be fully charged overnight on receipt

Charges 2-6 (Conditioning Cycles):

• It is very important to fully charge the battery and then use it until the device says low battery (approximately 20%)

• There is no need to force a discharge—just use the device as normal

• Do not top up the battery during these first 3-4 cycles until it reaches about 20% charge

• Do not let the battery run completely flat, especially during the first 3-4 cycles

After Conditioning:

• The best practice to lengthen battery life is to only place the device on the charger when it needs charging

• This type of battery can typically be cycled around 500 times with proper care

• A battery does not half-cycle—even if the battery was 80% charged, a full cycle will be used when it is placed on charge

Battery Calibration :
For optimal performance, calibrate your newly installed battery:

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 Guidelines :

• Store in a cool, dry place

• If storing for extended periods, maintain approximately 25% charge

• Capacity loss is minimal (about 2% per year) under proper storage conditions

Swollen Battery Warning :
If your old battery is swollen, handle with extreme caution. Do not puncture, crush, or apply heat—this can cause fire or explosion. Properly dispose of swollen batteries at authorised recycling centres. Learn more about safe handling of lithium-ion batteries and proper disposal methods.

Proper Disposal:
Never throw lithium-ion batteries in household trash. Always recycle through authorised electronic waste recycling centres. Tape over the terminals before disposal to prevent short circuits.

Installation Information

⚠️ IMPORTANT: This is an intermediate-level repair requiring careful attention .

The Nokia G22 and C31 feature non-removable battery designs, which means professional-grade tools and techniques are necessary for safe removal of the old battery. Official repair guides indicate this replacement takes approximately 35 minutes to 1 hour and has a medium difficulty rating .

Tools You May Need :

• Precision screwdriver set

• Plastic opening tools and spudgers

• Suction cup

• Tweezers

• Heat gun or heating pad (for softening adhesive)

• Isopropyl alcohol for adhesive softening

Official Repair Guides:
Step-by-step repair guides are available from iFixit for the Nokia G22 battery replacement procedure, which can be followed for these compatible models .

Important Safety Precautions:

• Professional installation by a qualified technician is strongly recommended if you lack experience

• Never use metal tools near the battery – they can puncture it and cause fire or explosion

• Disconnect the battery before attempting any other repairs

• Use ESD (electrostatic discharge) protection

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

• Once installed, the battery cannot be returned

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.
