iPhones come with Li-On (Lithium Ion) Batteries and their performance is measured not how big the Li-On cell is but its capacity that is measured by mAh (milliampere per hour). Although all iPhone models till date have 3.8V battery but Apple has provided different mAh for different models based on their architecture, form factor (size, design) as well as performance parameters. iPhone 6, iPhone 6S, iPhone 7 and iPhone 8 all have more or less ~ 2000 mAh batteries. However, iPhone X, iPhone XR, iPhone 11, have higher mAh battery i.e. ~ 3000 mAh. iPhone 11 Pro Max and iPhone 12 Pro Max have highest mAh, which is almost 3900.
