People who own iPhones know that these devices come with a hefty price tag, so naturally, they would want their iPhones to have a longer lifespan. One of the key factors in achieving this is prolonging the battery life of the iPhone, as often the need to replace an iPhone arises due to deteriorating battery performance.
Most modern smartphones can last a whole day on a single charge, eliminating the need to carry around a portable charger or recharge the device multiple times a day. Users need to ensure that the battery remains in good condition throughout the lifespan of the phone.
One method to extend the battery life of a smartphone is to minimize the battery reaching a full 100% charge. A fully charged battery undergoes stress, which can impact the long-term health of the battery and accelerate its degradation.
For iPhone users, there is an option to set a charging limit to prevent the battery from reaching 100% capacity. By enabling this feature, users can leave their device plugged in overnight without worrying about overcharging.
To have better control over the iPhone battery’s charge level, users can utilize a feature called “Charge Limit.” By setting a charge limit, one can prevent the battery from reaching its maximum capacity, thereby reducing battery stress.
This charge limit feature can be enabled on iPhone 15 or newer models by navigating to “Settings” > “Battery” > “Charging,” where users can choose a percentage between 80% to 100% in 5% increments. It’s important to note that optimizing battery charging can only be turned on when the battery reaches 100%.
According to Apple, implementing a charging limit can extend the lifespan of the smartphone battery, and the iOS system may recommend this feature based on the user’s usage patterns. Even setting the charge limit at 95% can have long-term benefits for an iPhone’s battery life.
However, if a phone remains plugged in after reaching a full charge, there’s no need to lose sleep over it. Patrick Holland, an editor at CNET and a mobile reviewer, mentioned, “Besides reaching a full charge, there are various factors that affect battery lifespan and durability. Apple and other phone manufacturers use software to minimize these factors and even provide customers with options to control them. There’s a balance to be struck, and people need not fear fully charging their smartphones.”
Even after activating the charge limit, users may occasionally see their iPhones reaching 100% charge. Apple clarifies that if the charge limit is set below 100%, the iPhone may occasionally fully charge to maintain an accurate estimate of the battery charge status.
Additional tips for maintaining iPhone battery health include keeping the battery level around 50%, turning off the device when not in use to prevent excessive battery drain, storing the phone in a cool and dry environment with temperatures ideally below 90 degrees Fahrenheit (32 degrees Celsius), and if the iPhone remains unused for over six months, it should be turned on and charged to 50% every six months.
In cases where an iPhone needs to be stored for an extended period, it may experience a low power state, requiring around 20 minutes of charging to power on.
