One of the best features for iPhone users that often goes underutilized is the battery charging limit set to 80%. This feature is especially useful in prolonging the overall lifespan of your iPhone’s battery.

Lithium-ion batteries, like those in iPhones, have a limited number of charge cycles before they begin to degrade. By setting your iPhone to charge up to only 80%, you can significantly reduce the rate at which degradation occurs. This charging strategy is rooted in battery chemistry – Lithium-ion batteries experience less stress when they’re not charged to full capacity, thus extending their longevity.

This feature becomes incredibly handy with the introduction of ‘Optimized Battery Charging’ on iOS. Optimal charging slows down the charging process when it reaches 80%, and based on your usage patterns, it will finish charging to 100% just before you typically start using your phone again. However, if you’re aiming to maintain an even healthier battery state, you can manually manage your charging habits to avoid going beyond 80%.

To get started with setting a charging limit on your iPhone, you can use Shortcuts or simply keep an eye on your phone as it charges and disconnect it once it hits that 80% mark. While this manual method may not be as convenient as automated features, it’s still a valuable practice for those looking to maximize their battery’s effective lifespan.

Moreover, this approach not only serves in favor of longevity but also aids in energy conservation, making it an eco-friendlier option for charging devices. It’s a simple change with negligible impact on day-to-day usage for most users but potentially significant gains for the health and duration of your iPhone’s battery life over time.

Embracing this often-ignored feature could help ensure that your device stays functional and efficient throughout its life. So next time you plug in your iPhone, consider stopping the charge at 80% – your future self (and your wallet) might thank you as you potentially stave off a costly battery replacement and do a bit of good for the environment too.
