During the launch event, Apple boasted that the iPhone 13 series battery was more durable than the iPhone 12 series. It's just that the Cupertino-based tech giant didn't say how much battery capacity is embedded, or how long it takes to perform daily tasks.
For this last question, when we review the official website, we can see the results of Apple's iPhone battery testing. Not only one test was carried out, the company commanded by Tim Cook carried out up to three tests.
There are video playback tests, online video playback, and audio playback. The result does look an increase compared to the iPhone line that was released last year.
Here's a comparison of battery duration between iPhone 12 and iPhone 13
iPhone 12 Series online video playback test results:
iPhone 12 Mini: 10 hours
iPhone 12: 11 hours
iPhone 12 Pro: 11 hours
iPhone 12 Pro Max: 12 hours
iPhone 13 Series online video playback test results
iPhone 13 Mini: 13 hours
iPhone 13: 19 hours
iPhone 13 Pro: 20 hours
iPhone 13 Pro Max: 25 hours
Therefore, Apple claims that when playing online videos, the iPhone 13 Pro and 13 Pro Max can play 9 hours and 13 hours longer than their predecessors. Even the iPhone 13 Mini, online video playback time is up to 13 hours.
This ability is surprising. Underneath its tiny body, the iPhone 13 Mini has a longer time to play online videos, not only than its predecessors, even with the iPhone 12 Pro Max.
Until now no one knows why the iPhone 13 Mini is able to do this. Most likely because the A15 Bionic chip is able to save much less power than the A14 Bionic.
Because even though the iPhone 13 Mini has a 9% increase in battery capacity compared to the iPhone 13 mini, in theory it will never be able to beat the iPhone 12 Pro Max in terms of battery life because it has a much larger capacity.
