As reported by MacRumors, the iPhone 15 series introduces a new option within its battery settings menu: the ‘80% limit.’ While ‘optimized battery charging’ was already in place to maintain the battery at 80% overnight and complete the charge to 100% just before waking up, the 80% limit serves as a stricter cap on the charging process.
By choosing to charge your iPhone only up to 80%, rather than its full 100%, you may sacrifice some daily longevity. However, the potential benefit is that your phone could consistently deliver the same level of daily use for a more extended overall period. This could be perceived as a net gain for users concerned about preserving their battery health.
