The short answer

The iPhone 16 Pro battery stores 13.942 watt-hours.

The calculations below use the model-specific figure of 3,582 mAh. This is not a generic assumption for every smartphone.

Power-bank calculation

How many full charges?

We take 75% of the power bank's stated Wh and divide by this phone's 13.942 Wh. This remains a planning estimate.

5,000mAh class≈ 1×

18.5 Wh rated → 13.9 Wh planned delivery

10,000mAh class≈ 2×

37 Wh rated → 27.8 Wh planned delivery

20,000mAh class≈ 4×

74 Wh rated → 55.5 Wh planned delivery

(Power-bank Wh × 0.75) ÷ 13.942 Wh

A cold or older battery can supply less energy.

Cold and battery ageing

The estimate uses the battery data and calculation assumptions shown with this result. That is not a measurement of the battery’s current condition. Cold and battery ageing are not calculated separately.

Cold is not the same as wear. Cold can temporarily limit the available energy and the power that can be delivered. Ageing can permanently reduce the storage capacity, even when the screen shows ‘100% charged’.

Follow the temperature limits for charging and using from the manual of your model. Check important applications with your own setup.

Frequently asked questions

Keep energy and charging power separate.

How many Wh does the iPhone 16 Pro battery store?

The model-specific source gives 13.942 Wh and 3,582 mAh. Watt-hours are the useful basis for comparison with a power bank.

How often can a 10,000mAh power bank charge the iPhone 16 Pro?

A power bank rated around 37 Wh provides about 2 full charges in this estimate. We assume 75% of its rated energy reaches the phone battery.

Does 13.942 Wh mean the phone charges at 13.942 W?

No. Wh is stored energy; W is charging power at a particular moment.
