iFixit's teardown documented the iPhone 11 battery at 3110mAh and 11.91Wh. Apple states that batteries in iPhone 14 models and earlier are designed to retain 80% of original capacity at 500 complete charge cycles under ideal conditions; this is a different metric from ESC's stated cycle-life target and should not be treated as a direct like-for-like durability comparison. iFixit

Quality Control Process

Incoming Material Inspection

Battery cells, PCM boards, flex cables, connectors and supporting materials are inspected before production.

Cell Grading

Cells are checked and grouped according to voltage, capacity, internal resistance, dimensions and consistency.

Capacity Testing

Professional battery testers verify actual discharge capacity against the approved 3110mAh specification.

For B2B purchasing, measured capacity is more meaningful than relying only on printed capacity information.

PCM Testing

The protection circuit is checked for overcharge, over-discharge and short-circuit protection.

Flex and Connector Inspection

Flex position, connector orientation, welding quality and electrical continuity are inspected to reduce installation failures.

Charging and Discharging Testing

Finished batteries are checked for charging behavior, discharge performance, voltage stability and abnormal current.

Aging Testing

Aging inspection helps identify abnormal self-discharge and unstable batteries before shipment.

Final Inspection

Appearance, dimensions, labeling, battery model, packaging and order quantity are checked before shipment.

ESC recommends verifying actual capacity, protection functions, temperature performance and device compatibility as part of professional battery supplier evaluation. 易充电

OEM and Private Label Service

Custom Battery Labels

Custom battery labels can include customer logos, model information, capacity, voltage, barcode and production traceability information.

Private Label Packaging

Customized retail packaging can be developed for wholesalers, distributors and independent battery brands.

Barcode and SKU Management

Custom barcodes and SKU labels help buyers manage large replacement battery inventories across different iPhone models.

Flexible Branding

ESC branding, standard packaging or customized private label solutions can be selected according to the customer's sales channel.

Mixed-Model Orders

Professional wholesale customers can combine multiple phone battery models into one purchasing program, subject to the mixed-model MOQ.

How to Choose a Reliable Replacement Battery Supplier

Evaluate cell quality, testing capability, assembly details, production consistency and installation support before purchasing smartphone, tablet or laptop replacement batteries.

Verify Battery Model Coverage and Compatibility

Choose a supplier with broad coverage for smartphone, tablet and laptop batteries. Confirm the original battery code, device model, connector position, dimensions, rated voltage and system compatibility before ordering.

A supplier with an established model database can reduce incorrect shipments, installation problems and compatibility-related returns.

1

Check the Quality of Cells and Electronic Components

Battery quality starts with the raw materials. Ask the supplier about:

  • Battery-cell manufacturer and grade
  • Actual cell capacity
  • Cell cycle life
  • PCB and protection-chip solution
  • Connector and flex-cable quality
  • Traceability of key components

Reliable suppliers should use graded cells rather than selecting components only by the lowest price.

2

Review Incoming Material Inspection and Cell Grading

Cells should be tested and grouped according to:

  • Capacity
  • Voltage
  • Internal resistance
  • Self-discharge
  • Thickness and dimensions
  • Appearance

Proper cell grading improves consistency between batteries from the same production batch and reduces abnormal runtime, swelling and early failure.

3

Require Complete Electrical and Compatibility Testing

A professional supplier should test more than the open-circuit voltage. Quality verification should include:

  • Charging and discharging performance
  • Actual capacity
  • Battery current
  • Protection functions
  • Cycle count and battery data
  • Fuel-gauge parameters
  • Device compatibility
  • Temperature performance

Professional battery testers can perform charging, discharging, current calibration and precise parameter comparison, helping identify batteries whose measured data does not match the approved specification.

4

Evaluate Automation and Production Consistency

Automated production processes normally provide better consistency and higher capacity than heavily manual assembly.

Important processes may include:

  • Automatic cell sorting
  • Automatic welding
  • Automatic PCB testing
  • Automatic adhesive application
  • Barcode traceability
  • In-line functional inspection

Automation does not replace quality control, but it helps reduce variation caused by manual positioning, welding and assembly.

5

Inspect Assembly Details

Small assembly details have a major effect on installation efficiency and product reliability.

A well-finished battery should include:

  • Pre-applied battery adhesive
  • Dust-proof protective film
  • Protective sleeve around the flex cable
  • Fixed flex-cable position
  • Stable connector orientation
  • No loose or moving battery cable
  • Clean edges and accurate dimensions

These details reduce flex-cable damage, dust contamination, installation movement and incorrect connector alignment.

6

Confirm In-Process and Final Quality Inspection

The supplier should conduct inspection throughout production rather than checking only finished goods.

Recommended checkpoints include:

  • Incoming material inspection
  • Cell grading
  • PCB and BMS testing
  • Welding inspection
  • Assembly inspection
  • Capacity testing
  • Aging testing
  • Appearance inspection
  • Packaging inspection
  • Final random inspection

Ask whether inspection data can be traced back to the production batch.

7

Compare Capacity Claims, Defect Rate and Certification

Do not select batteries based only on the highest printed capacity.

A credible supplier should provide:

  • Tested capacity data
  • Clear rated voltage and energy
  • Customer-reported defect rate
  • Warranty policy
  • CE, RoHS, FCC, MSDS and UN38.3 documentation where applicable
  • Model-specific certification support

Exaggerated capacity labels without matching cell space, weight and test data are a significant purchasing risk.

8

Follow Correct Battery Installation Procedures

Even a qualified battery can fail if it is installed incorrectly.

Before installation:

  • Discharge the original battery below 25%
  • Power off the device
  • Use non-metallic opening tools
  • Disconnect the battery before handling other internal components
  • Avoid puncturing, bending or crushing the cell
  • Remove the protective film from the adhesive correctly
  • Align the battery and connector before pressing it into place
  • Confirm that the flex cable is not folded, stretched or trapped
  • Reinstall screws and brackets in their original positions
  • Test charging, battery recognition and device functions before final sealing

The installation guide specifically warns that a charged lithium-ion battery may catch fire or explode if punctured, and instructs technicians to power off the phone before disassembly.
