Phone battery capacity

Apple

iPhone 13 Pro

The 13 Pro battery stores slightly less energy than the standard iPhone 13 despite the Pro name.

Direct answer

The iPhone 13 Pro battery stores 11.97 watt-hours.

Every calculation below uses the model-specific 3,095mAh figure. This is not a generic smartphone assumption.

Rated energy: 11.97Wh
Rated capacity: 3,095mAh
Nominal voltage: 3.87V

Power-bank calculation

How many full charges?

We take 75% of the power bank’s rated Wh and divide it by this phone’s 11.97Wh. This is a planning estimate, not a charging guarantee.

5,000mAh class≈ 1.2×

18.5Wh rated → 13.9Wh planned delivery

10,000mAh class≈ 2.3×

37Wh rated → 27.8Wh planned delivery

20,000mAh class≈ 4.6×

74Wh rated → 55.5Wh planned delivery

(power-bank Wh × 0.75) ÷ 11.97Wh

Capacity is not speed

11.97Wh tells you how much.
Charging power tells you how fast.

Wired chargingFast-charge capable with a 20W or higher adapter

The phone, USB power adapter and cable must negotiate a compatible charging profile. Use certified equipment suitable for Canada.

Wireless chargingUp to 15W with MagSafe; up to 7.5W with Qi

Alignment, heat and charger certification affect real charging power.

Frequently asked

Keep energy and charging power separate.

How many Wh is the iPhone 13 Pro battery?

The model-specific source lists 11.97Wh and 3,095mAh. Watt-hours are the useful figure when comparing it with a power bank.

How many times can a 10,000mAh power bank charge the iPhone 13 Pro?

A power bank rated around 37Wh provides about 2.3 full charges in this planning calculation. We assume 75% of rated energy reaches the phone battery.

Does 11.97Wh mean the phone charges at 11.97W?

No. Wh is stored energy; W is charging power at a point in time.
