While the iPhone 15 series has only recently hit the market, diligent reviewers have already unearthed an intriguing feature that Apple didn’t highlight during its keynote presentation. This feature has the potential to significantly extend the lifespan of your iPhone’s battery.
To clarify, we’re not discussing how long your iPhone lasts on a single charge, but rather how quickly the battery degrades over its entire lifespan. Users with older iPhones, like the six-year-old iPhone X, may have noticed that reaching 100% charge doesn’t take as long as it did when the device was brand new.
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.
Please note that this feature is currently available on iPhone 15, iPhone 15 Plus, iPhone 15 Pro, and iPhone 15 Pro Max. Apple’s plans regarding its availability on older iPhone models, even those updated to the latest iOS 17, have not been confirmed at this time.
Here’s how to activate the 80% charging limit on your iPhone 15:
- Open Settings.
- Tap Battery.
- Select Battery Health & Charging.
- Choose Charging Optimization.
- Toggle on ‘80% Limit.’
This feature allows users to make a conscious choice between maximizing daily battery life and prolonging the overall health of their iPhone’s battery.
