Galaxy Z Flip4 phones use two separate internal battery cells. Confirm the number printed on the original component before ordering. Do not rely only on the phone name, battery position or appearance because the two cells have different capacities, shapes and connectors. This listing is specifically matched to the supplier's 2630mAh F721B main-battery record for EB-BF723ABY and EB-BF725ABY.
Product condition and supplier testing
This is a brand-new AMPLUS aftermarket battery, not a genuine Samsung Service Pack battery and not a pulled component. The supplier describes its AMPLUS battery as a full-capacity, zero-cycle lithium-polymer replacement and states that each unit is tested before shipping. The supplier also lists overcharge, overheating, overload, short-circuit, temperature-control and PTC protection, plus RoHS and CE certification. These are supplier specifications; actual runtime depends on the phone, software, network conditions, charging habits and installation quality.
When battery replacement may help
A correctly diagnosed battery replacement may help when a compatible Z Flip4 has reduced runtime, unexpected shutdowns, inconsistent battery percentage or a confirmed battery fault. Similar symptoms can also result from the second battery cell, charging hardware, damaged interconnect cables, software, liquid damage or a main-board fault. Replacing this battery is not guaranteed to correct every charging, heat, boot-loop or power problem. Professional diagnosis is recommended before ordering.
What is included
The package contains one AMPLUS 2630mAh replacement battery matching EB-BF723ABY or EB-BF725ABY. Adhesive, tools, the second Z Flip4 battery, installation labour and other parts are not included. Compare the connector, shape and printed battery number with the original part before removing protective packaging or beginning installation.
Installation and lithium-battery safety
Galaxy Z Flip4 battery replacement is an advanced repair involving adhesive-backed covers, delicate flex cables and a folding chassis. Power the phone off and disconnect the batteries before working around internal connectors. Never bend, puncture, crush, short-circuit or expose a lithium battery to excessive heat. Stop using or handling any battery that is swollen, leaking, damaged or unusually hot.
Test battery detection, charging and normal operation before resealing the device. Opening a sealed phone can reduce its original water resistance. New adhesive does not guarantee restoration of the factory ingress-protection rating. Professional installation is strongly recommended. Installation damage, torn flex cables, bent connectors, puncture damage and damage caused by an incompatible device are not product defects.

Frequently asked questions
Is this the 1070mAh Z Flip4 battery?
No. Exact SKU AMPBRMain-F721 is the 2630mAh battery matching EB-BF723ABY or EB-BF725ABY. Match the original printed battery number before ordering.

No. It is an AMPLUS branded aftermarket replacement.
Does the listing include both Z Flip4 batteries?
No. It includes one 2630mAh battery only. The second battery must be purchased separately if required.
Will it fit every regional Z Flip4?
The supplier specifically verifies F721B. Compatibility with another regional model should be confirmed from the original EB-BF723ABY or EB-BF725ABY marking before purchase.
Can I install it myself?
Professional installation is recommended because foldable-phone disassembly and lithium-battery handling carry a high risk of damage.
