I Never Charge My iPhone to 100%. Here's Why and How I Do It

The article discusses the author's strategy for charging their iPhone to maximize its battery lifespan. The author explains that they never charge their iPhone to 100% and instead set a charge limit, typically around 80-90%. The rationale behind this approach is that lithium-ion batteries, which are used in iPhones, perform best and last longer when they are not constantly charged to their full capacity. Repeatedly charging the battery to 100% can cause it to degrade more quickly over time, reducing the overall lifespan of the battery. By setting a charge limit, the author can maintain a healthier battery and extend the usable life of their iPhone. The article also provides instructions on how to set a charge limit on various iPhone models, ensuring that the battery is not overcharged. The author's approach aims to optimize the iPhone's battery performance and longevity, allowing the device to be used for a more extended period without significant battery degradation.
