Here we list and explain the battery capacities of every iPhone, from the original iPhone from 2007 to the latest iPhone 15 series, and even some rumors about the upcoming iPhone 16 family.
Measuring iPhone battery life in hours of actual usage (as Apple likes to do) is not an accurate metric for comparison purposes because many usage and environmental factors play a role .
However, we can rely on simple technical specifications to tell us the battery capacities of each iPhone.
Apple is notoriously secretive about these battery specs, mainly because smartphones from competitors like Samsung have much larger battery capacities. We can only find out the battery capabilities by removing the battery from the phone and checking the specifications printed on it.
These are measured either Milliampere hours (mAh) or Watt hours (What).
Milliampere-hours are a measure of electrical load, while a watt-hour is equivalent to one watt of energy consumed for one hour. And it’s the energy consumed that matters when we measure actual battery life.

Wh is a more accurate and consistent way to compare the total amount of energy that similar types of batteries can store.
And it all depends on the battery voltage, which mAh ignores, which determines the power (wattage) of a battery.
If the mAh is the same, the higher the voltage, the more power actually stored.
Volts (V) are a measure of electrical pressure. Amps (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 1000) divided by V = mAh.
The lithium batteries that power most portable electronic devices have a voltage of around 3.6 V, but some external batteries (such as Apple’s 7.62 V MagSafe battery) have a higher voltage, which means that they actually carry more power than their mAh implies.
Here we list the battery capacity of every iPhone ever released in mAh and Wh.
