Important Battery Conditioning Information

New Lithium-Ion batteries require proper conditioning to achieve optimal performance:

• The battery will reach its maximum capacity and performance level after 2 to 3 complete charge and discharge cycles 

• Full performance and longevity is only achieved after 3 to 5 complete charge and discharge cycles 

• After you go through these initial cycles, the battery will be fully conditioned

• To maximize battery lifespan, avoid letting the battery drain completely to 0% before recharging

Installation Information

This is an intermediate-level repair requiring careful attention. The battery connects to the motherboard via a flexible cable with a connector, so no soldering is typically required. A complete toolkit is included to assist with the replacement .

Installation Steps Overview :

1. Power off the device and remove the SIM tray

2. Remove the back cover using plastic pry tools

3. Remove all screws securing the internal panels

4. Disconnect the old battery from the motherboard

5. Carefully remove the old battery - if stubborn, use high-concentration isopropyl alcohol to loosen adhesive 

6. Install the new battery ensuring proper alignment of the connector

7. Reassemble the device and secure with new rear adhesive if needed

8. Test the device to verify charging and battery performance

Important Tips :

• Never use metal pry tools when working near the battery, as puncturing a lithium battery can cause a fire or explosion

• Watch YouTube videos related to Samsung Galaxy A21s battery replacement for visual guidance 

• T7000 glue or new pre-cut adhesive is recommended for reattaching the back cover 

Important Safety Precautions:

• Professional installation by a qualified technician is strongly recommended

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

• Use ESD (electrostatic discharge) protection
