The iPhone 15 has a new optimized charging setting, here’s how it works

Discover the latest feature of the iPhone 15 that aims to address battery longevity concerns: the optimized charging setting. This new setting allows you to limit the battery charge to 80 percent, preventing potential drop-offs in battery capacity. Apple provides an explanation of how the feature works, stating that your iPhone will charge up to around 80 percent and then stop charging. If the battery level falls to 75 percent, charging will resume until it reaches approximately 80 percent again. It’s important to note, however, that occasional charging past 80 percent may still occur to maintain accurate battery state-of-charge estimates. This addition to the existing Optimized Battery Charging setting could be a game-changer for iPhone users, addressing one of the common issues faced by iPhone 14 and iPhone 14 Pro owners. Furthermore, the iPhone 15 series introduces the ability to track battery charge cycle count. Stay tuned as we await the release of iOS 17.0.2 to see if this new feature lives up to its promise.

Overview

Apple’s new charging setting for iPhone 15

Apple has introduced a new optimized charging setting for the iPhone 15 models. This feature limits the charging of the battery to 80 percent, aiming to address the battery longevity complaints that were prevalent with the previous iPhone 14 models.

Purpose of the charging limit

The purpose of implementing the charging limit is to prevent battery capacity dropoffs, which many iPhone 14 and iPhone 14 Pro owners experienced. By limiting the charging to 80 percent, Apple aims to maintain battery health and improve overall battery longevity.

Response to battery longevity complaints

Apple’s decision to introduce the charging limit setting is a response to the complaints from iPhone 14 users who noticed significant battery capacity issues. The company is actively listening to user feedback and working towards improving the overall battery performance in their devices.

Explanation of the charging limit setting

When the 80% Limit setting is enabled, the iPhone 15 will charge up to approximately 80 percent and then stop charging. If the battery charge level drops to 75 percent, charging will resume until it reaches about 80 percent again. Additionally, the phone will occasionally charge to 100 percent to maintain accurate battery state-of-charge estimates.

How the Charging Limit Works

Charging up to 80 percent

With the new charging limit setting, your iPhone 15 will charge up to around 80 percent and then stop. This helps prevent overcharging and reduces stress on the battery, ultimately enhancing its longevity.

Resuming charging at 75 percent

If the battery charge level drops to 75 percent, the charging will automatically resume until it reaches approximately 80 percent. This ensures that your device remains adequately charged without continuously charging to 100 percent.

Occasional charging to 100 percent

To maintain accurate battery state-of-charge estimates, the iPhone 15 with the 80% Limit setting enabled will occasionally charge to 100 percent. This allows the device to calibrate and provide accurate battery information to the user.

Comparison to Optimized Battery Charging

The new 80% Limit setting complements the existing Optimized Battery Charging feature available on Apple devices. The Optimized Battery Charging setting holds the battery charge at 80 percent and then brings it up to full just before the user typically needs to use the phone, based on their usage patterns.

Impact on battery capacity dropoffs

The implementation of the charging limit aims to prevent unexpected battery capacity dropoffs, which were frequently reported by iPhone 14 and iPhone 14 Pro owners. By maintaining a consistent charging level and reducing stress on the battery, Apple aims to improve battery health and longevity.

Testing and Updates

Testing the setting on review devices

Upon testing the charging limit setting on review devices, it was observed that the iPhones occasionally charged past 80 percent, contrary to the intended limit. This is something that users can expect to see happening occasionally, as clarified by Apple.

Charging past 80 percent occurrence

Although the charging limit is set at 80 percent, there may be instances where the iPhone 15 charges past this limit. Apple has programmed the device to occasionally charge to 100 percent to ensure accurate battery state-of-charge estimates.

New iOS update and its effects

Apple has recently released the iOS 17.0.2 update for the iPhone 15 series, which includes enhancements and bug fixes. The impact of this update on the charging limit setting is being investigated to determine if it improves the adherence to the 80 percent charging limit.

Benefits of the 80 Percent Limit

Preventing battery capacity dropoffs

One of the key benefits of the charging limit setting is its ability to prevent unexpected battery capacity dropoffs. By maintaining the charging level around 80 percent, the iPhone 15 aims to mitigate the degradation of the battery and extend its overall lifespan.

Charge cycle count visibility

In addition to the charging limit, the iPhone 15 series allows users to view the charge cycle count for their battery. This feature provides valuable information about the battery’s usage history and helps users monitor the health of their battery.
