iPhone Battery Capacity mAh: Detailed Analysis and Comparison by Model

Complete List of iPhone Battery Capacities

The table below shows the battery capacities for each iPhone model from the first one produced to the latest in the line, including the newly released iPhone 16 and 16 Pro models. Apple has placed certain strategic constraints on the level of battery power to assign across different devices in a given category, which can be observed from their regulatory filings and several technical teardowns done on the devices

While comparing Apple’s flagship devices, it becomes evident that Pro variants have greater capacity and advantages, although the real-world efficiency owing to the display/processor differences tend to alter this reality

iPhones have the capacities to manage high power charging sessions with advanced low power protocols which improve the health of the battery

Runtime Comparisons

There is a clear difference in estimates provided by the different sources:

• iPhone 16 Pro Max: 11h 22min continuous use
• iPhone 15 Pro Max: 9h 40min with 4,433mAh battery
• iPhone 14 Plus: 8h 45min screen-on time

The reason for the paradox of the iPhone 15 Pro Max dominating over newer models is due to the ProMotion display’s 10-120Hz variable refresh rate which cuts down power usage during stationary viewing content.

Patterns of Health Deterioration

The health of a lithium-ion battery generally declines according to the following milestones:

• A charge cycle will yield a 2% loss in capacity
• 8-10% loss after 300 cycles
• 15-20% loss after 500 cycles

Performance drops are managed by ios only after the capacity breaches 80%, and top processors are then capped to prevent unanticipated shutoff. Users can monitor this via Settings > Battery > Battery Health & Charging.

Most Efficient Adapter Combinations

• iPhone 16 Series: 30W USB-C PD for 45W charging
• iPhone 15 Series: 20W USB-C PD
• MagSafe Wireless: 20W minimum for 15W output

Battery Safety Controls

Charging Efficiency: Battery temperatures have a critical impact during charging:

• Ideal Range: 16°C to 22°C
• Throttling Threshold: 35°C (50% speed reduction)
• Safety Cutoff: 45°C (pauses charging)

iPhone 16 Series Breakthroughs

• 4,685mAh Battery: A record high for iPhones
• Stacked Battery Tech: 10% greater energy density than predecessors
• Combo of AI and Predictive Analytics: Optimized discharge based on usage pattern predictions

iPhone 14 Plus Anomaly

Even with the identical 4,325mAh capacity to Pro Max, the Plus model’s video playback time exceeds by 12 hours (27h vs 24h) due to a lower-power LCD display as opposed to ProMotion OLED .

Upcoming Expectations

What experts are saying:

• 2025 Models: Utilizing graphene anodes, batteries reaching 5,000mAh capacity
• For 2026: Full charge in less than 10 minutes with solid-state batteries
• 2027: Self-healing battery membranes that double cycle lifespan

This detailed study shows how Apple takes a delicate approach to battery technology that goes beyond just capacity figures. By employing advanced power control strategies and relentless fine-tuning of both hardware and iOS software, iPhones maintain optimal battery longevity throughout use, which is better than most Android devices, even though iPhones have lower power ratings than Androids.
