🔋 Is Your S24 Ultra Battery Failing?
Lithium batteries degrade with each charge cycle. After 2–3 years of heavy use, capacity loss becomes noticeable.
📉 Battery drains fast — full charge lasts only a few hours
🔌 Won't hold charge — drops from 80% to 20% within minutes
🌡️ Overheating during use — battery gets very warm while charging
📴 Random shutdowns — phone turns off at 20–30% battery
🔢 Incorrect percentage — battery level jumps around erratically
💥 Swollen back glass — back panel lifting away from the frame
✅ A battery replacement fixes all of these symptoms. This AMPLUS 4855mAh battery restores full-capacity performance to your S24 Ultra.
⚠️ Professional Installation Strongly Recommended
The S24 Ultra uses a bonded glass back with adhesive. Incorrect installation risks damaging the battery, display, or internal components.
🔧
Heat and Disassembly
The back glass is bonded with adhesive. Controlled heat is required to open the device safely without cracking the glass.
🔋
Battery Removal
The battery is held with strong adhesive pull-tabs. Improper removal can puncture the cell — a fire risk with lithium batteries.
💧
Water Resistance
Opening the device breaks the IP68 seal. Re-sealing is possible but the original factory rating will not be restored.

Frequently Asked Questions
Is this battery compatible with the Samsung Galaxy S24 Ultra?
Yes. This battery is made for the Samsung Galaxy S24 Ultra (model number S928B). It is not compatible with the S24, S24 Plus, or any other Samsung model. The S24 Ultra has a unique battery footprint and connector position. Always check your model number before purchasing. You can find it on the SIM tray or in Settings — About Phone — Model Number.
What does aftermarket quality mean for a battery?
Aftermarket means the battery is not made by Samsung. It is built by AMPLUS to match OEM specifications. AMPLUS uses new lithium polymer cells, new connectors, and new PCBAs in every unit. The battery is tested before leaving the factory. ROHS and CE certifications confirm it meets international safety standards. The 4855mAh capacity is approximately 97% of the Samsung-rated 5000mAh — a negligible difference in real-world use. Aftermarket batteries are widely used across the global repair industry.
Can I install this battery myself?
Technically yes, but professional installation is strongly recommended. The S24 Ultra uses a bonded glass back that needs controlled heat to open safely. The battery is held with strong adhesive pull-tabs. Incorrect removal can puncture the lithium cell — a fire risk. You also need a heat source, opening picks, spudger, and screwdrivers. If your current battery is swollen, do not attempt DIY — bring the phone to a technician. JPC Mobile offers professional installation at our Forest Lake Brisbane store. Call 0480 039 913 to book.
Will replacing the battery affect water resistance?
Yes. The S24 Ultra is IP68 rated from the factory. Opening the device breaks that factory seal. Water resistance can be partially restored using new adhesive during reassembly, but the original IP68 rating will not return. After a battery replacement, treat the phone as water-resistant rather than waterproof. Avoid submerging it in water. This applies to any battery replacement on any IP68 device — including repairs done at Samsung's own service centres.
Will this battery show 100% health in Samsung settings?
Aftermarket batteries often show a reading in Samsung diagnostics. The result may display 100% or may not populate, depending on firmware version. This is normal with aftermarket cells and does not indicate a fault. Real-world performance — how long the phone lasts between charges — is the better measure. A 0-cycle AMPLUS battery will outperform a degraded original battery at 80% capacity, regardless of what the diagnostics screen shows.
Does this battery support Samsung fast charging?
Yes. This battery works with Samsung's fast charging system on the S24 Ultra. The phone's charging circuitry manages the fast charging protocol. The battery needs to accept the charge correctly — and the AMPLUS PCBA is built for compatibility with Samsung's charging management. Fast charging and wireless charging behaviour is controlled by the phone. No settings changes are needed after installation.
Should I calibrate the new battery after installation?
Yes. After installation, run 2–3 full charge and discharge cycles. Charge to 100%, use the phone until around 10%, then charge to 100% again. This helps the phone's battery management read the new cell's capacity correctly. Battery percentage accuracy and charge time estimates improve after calibration. No special app is needed — just use the phone normally through a few complete cycles.
What does the 12-month warranty cover?
The 12-month warranty covers manufacturing defects and premature capacity failure under normal use. If the battery fails to hold a charge within the warranty period due to a manufacturing fault, JPC Mobile will arrange a replacement. The warranty does not cover physical damage from incorrect installation, puncture, bending, or water damage. DIY installation errors are not covered. Contact JPC Mobile with your order number and a description of the fault to start a claim. Warranty is handled locally at our Forest Lake Brisbane store.
Is it safe to receive a lithium battery by post?
Yes. JPC Mobile ships lithium batteries in compliant packaging that meets Australia Post and IATA regulations for lithium-ion cells. The battery is packed with protective materials to prevent short circuit and damage during transit. Lithium batteries are shipped daily by electronics retailers and repair businesses across Australia. Every order includes a tracking number. If your order arrives damaged, contact JPC Mobile immediately with photos before attempting to use the battery.
How do I know if my S24 Ultra battery needs replacing?
Common signs are a full charge lasting only 3–5 hours, random shutdowns at 20–30%, the back glass lifting slightly, and the phone getting hot while charging. You can check battery health by dialling *#0228# on your Samsung to open the battery status screen. If capacity is below 80%, replacement is recommended. The Samsung Members app also has battery diagnostics under Support — Phone Diagnostics — Battery Status. If your battery is swollen, replace it urgently — a swollen lithium battery is a fire risk.
