Here we list and explain the battery capacity of every iPhone, from the original 2007 iPhone to the very latest iPhone 14 series.
Measuring iPhone battery life in hours of real-world use (as Apple likes to do) isn’t an accurate measure for comparison purposes, since there are so many usage and environmental factors involved.
However, we can rely on clear technical specifications to tell us the battery capacity of each iPhone.
Apple is notoriously secretive about these battery specs, especially since smartphones from rivals like Samsung have much larger battery capacities.
These are measured in either Milliamper hours (mAh) or Watt hour (Wh).
Milliamp hours are a measure of electrical charge, while a watt-hour is equal to one watt of energy consumed for one hour. And it’s power consumption that matters when we measure actual battery life.

Wh is a more accurate and consistent way to compare the total amount of energy comparable battery types can store.
And it’s all about the battery voltage, which ignores mAh, which determines the wattage (power) of a battery.
If the mAh is the same, the higher the voltage, the greater the actual stored power.
Volts (V) is a measure of electrical pressure. Ampere (A) is a measure of current. Multiply V x A and you get Watts (W) which is a measure of power. So V × A = W.
You can convert watt-hours (Wh) to milliamp hours (mAh) using this formula: (Wh x 1,000) divided by V = mAh.
The lithium batteries that power most portable electronics have a voltage of about 3.6 V, but some external battery packs (such as Apple’s 7.62 V MagSafe Battery Pack) have a higher voltage, meaning they actually have more power than their mAh implies.
Here we list the battery capacity of every iPhone ever released, both in mAh and Wh.
