Apple has introduced a new feature aimed at addressing users’ concerns about iPhone battery life. With the iPhone 15, users now have the option to set an 80% charging limit, which can potentially extend the overall lifespan of their battery. This feature aims to alleviate the anxiety that many users have about preserving their iPhone’s battery health.
Traditionally, iPhone users have taken various measures to prolong their battery life, such as limiting their device’s usage or adjusting settings. With the new iPhone 15 lineup, Apple is offering a battery health setting that allows users to choose not to charge their device beyond 80% capacity, instead of reaching the standard 100% charge.
It’s important to note that the existing Optimized Battery Charging feature already stops charging when the battery reaches 80% and resumes charging to full capacity just before the user typically wakes up. However, the new setting, if activated, will permanently cap the charging at 80%.
The rationale behind this feature has rooted in the fact that charging efficiency has high up to 80%, but the last 20% consumes more energy and generates heat. Some users have adopted the practice of keeping their batteries within the 40% to 80% range to potentially extend their lifespan.
While this new feature may have some value for those who are particularly concerned about battery longevity, it may not be a significant game-changer for most users. In reality, users can continue to use their smartphones with automatic settings and charge them as needed. It’s worth remembering that all batteries degrade over time and will eventually require replacement.
Ultimately, the decision to use this feature or not will depend on individual user preferences and concerns about battery health. Apple’s introduction of this option allows users to have more control over their device’s battery management, but its impact on overall battery life may be relatively limited.
