Important Battery Information

First-Time Use and Conditioning:

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

• Before installation: Let your phone's battery drain below 25% before starting the repair. A charged lithium-ion battery may catch fire if damaged 

• Discharge battery below 25% before disassembling your phone to reduce safety risks 

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

• Calibration: After installation, calibrate your newly installed battery by charging to 100% and then fully discharging it 

• Optimal performance will be reached after these initial conditioning cycles

Proper Charging Habits:

• Use the original charger that came with your device for best performance (25W fast charging compatible)

• To prolong battery lifespan, charge when the level drops to 20-30% rather than letting it drain completely to 0%

• Avoid overcharging – unplug once fully charged

• Be sure to go through at least one charge cycle per month (charging to 100% and then completely running it down) to keep your battery running at its best possible performance 

Storage Guidelines:

• If storing for extended periods, maintain approximately 25-50% charge in a cool, dry place

• Capacity loss is minimal 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. In the interim before you get it fixed, do not charge the phone or use it . Properly dispose of swollen batteries at authorised recycling centres. Take your e-waste to an R2 or e-Stewards certified recycler .

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

⚠️ This is an intermediate-level repair requiring careful attention . The Samsung Galaxy S24 features a non-removable battery design, which means proper tools and techniques are necessary for safe removal of the old battery.

Samsung Official Repair Kit Contents :

• Heating pad

• Opening picks (Set of 6)

• Spudger

• Suction cup

• Tweezers

• Screwdriver (Philips PH000)

Installation Time Estimate: 1 - 2 hours 

Important Safety Precautions :

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

• Let your phone's battery drain below 25% before starting this repair – a charged lithium-ion battery may catch fire if damaged

• Completely power off your phone and unplug all cables

• Be careful not to overheat the phone – the battery is susceptible to heat damage

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

• Only insert opening picks up to 4 mm deep to avoid damaging the rear cameras or flash

• Use ESD (electrostatic discharge) protection

• Once installed, the battery cannot be returned

Key Installation Steps Overview :

1. Heat the back cover edges to soften adhesive

2. Use suction handle and opening picks to carefully separate the back cover

3. Remove thirteen 3.5mm screws securing the wireless charging coil and loudspeaker

4. Disconnect the battery cable press connector from the motherboard

5. Peel the battery pull tab and use firm, steady force to separate the battery adhesive

6. If having trouble, apply 1-2 drops of high-concentration (90%+) isopropyl alcohol to soften adhesive

7. Lift the battery until perpendicular and remove

8. Before reassembly, power on your phone to test all functions

9. Calibrate your newly installed battery after completing installation

Important Note on Water Resistance:

Retaining water resistance after the repair will depend on how well you reapply the back cover adhesive, but your device will lose its IP (Ingress Protection) rating .

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.
