Apple has also made significant improvements to battery life in the last few years through software optimizations; newer models tend to have better battery life compared to older models with the same battery sizes. Here is a general overview of the battery life of various iPhone models:
- iPhone 12 Pro Max: The iPhone 12 Pro Max has the largest battery of the iPhone models, and it can last up to 28 hours of talk time or up to 95 hours of audio playback.
- iPhone 12, iPhone 12 Mini, and iPhone 12 Pro: These models have a slightly smaller battery than the iPhone 12 Pro Max, but they can still last up to 20 hours of talk time or up to 65 hours of audio playback.
- iPhone 11, iPhone 11 Pro, and iPhone 11 Pro Max: These models have a battery that can last up to 17 hours of talk time or up to 65 hours of audio playback.
- iPhone XR: The iPhone XR has a battery that can last up to 16 hours of talk time or up to 65 hours of audio playback.
- iPhone XS and iPhone XS Max: These models have a battery that can last up to 20 hours of talk time or up to 60 hours of audio playback.
- and resolution of the display can impact battery life because a larger, higher-resolution display requires more power. The iPhone 12 Pro Max has the largest display of the iPhone models, followed by the iPhone 12, iPhone 12 Mini, iPhone 12 Pro, iPhone 11, iPhone 11 Pro Max, iPhone 11 Pro, iPhone XS Max, iPhone XR, and iPhone XS.
A more powerful processor will generally require more power, so it will impact battery life. The iPhone 12, 12 Mini, 12 Pro, and 12 Pro Max all have the A14 Bionic chip, which is the most powerful processor currently available on an iPhone. Additionally, the larger the display, the more power used.
