Apple's New iPhone Function When Your Battery Dies Beats Samsung And Google
What are the new specific charging limit percentages that iOS 18 will allow users to set?
iOS 18 will allow users to set new specific charging limit percentages for their iPhone 15 models. These include 85%, 90%, and 95% options, in addition to the existing 80% limit. This feature aims to improve battery longevity by allowing users to choose a charging limit that suits their needs.
How does setting a charging limit below 100% benefit the long-term health of an iPhone's battery?
Setting a charging limit below 100% can benefit the long-term health of an iPhone's battery in several ways. Lithium-ion batteries, which are commonly used in smartphones, including iPhones, have a limited lifespan measured in charge cycles. A charge cycle is completed when the battery is charged from a certain percentage to 100%, and then discharged back down to that percentage.
By setting a charging limit below 100%, the battery will undergo fewer complete charge cycles over time. This is because the battery isn't being charged to its maximum capacity with every charging session. As a result, the chemical processes that cause the battery's capacity to degrade over time are slowed down, extending the overall lifespan of the battery.
Moreover, when a battery is charged to 100%, the chemical reactions taking place inside it generate heat, which can cause stress on the battery's components and lead to a reduction in its overall lifespan. By setting a charging limit below 100%, these thermal stresses are reduced, thereby potentially increasing the battery's lifespan.
Additionally, charging a battery to 100% and keeping it there for extended periods can put additional stress on the battery and reduce its overall capacity over time. By setting a charging limit below 100%, the battery is maintained at a level that is less stressful for the system, potentially preserving its overall capacity and performance.
In summary, setting a charging limit below 100% can help extend the lifespan of an iPhone's battery by reducing the number of complete charge cycles, minimizing thermal stresses, and preserving the battery's overall capacity and performance.
Are there any similar 'findable' features available on Android devices, and do they include the new clock display feature?
Yes, there are similar "findable" features available on Android devices. Google's Find My Device app helps users locate their devices quickly and safely, even if the device is offline3. This feature is available for Android phones, tablets, and smartwatches. Additionally, Google is reportedly working on a power-off Bluetooth module to make devices easier to find even when they are turned off, similar to Apple's Find My feature.
As for the clock display feature, it appears that some Android phones can match the findable feature but not the new clock addition, at least for now. It is not clear if any current Android devices on the market can support the clock display feature when the device's battery has been depleted.
