Charging your iPhone to the optimal level is an important part of ensuring your device’s battery life lasts as long as possible. For optimized battery life, your phone should never go below 20 percent or never above 80 percent. It may put your mind at ease when your smartphone’s battery reads 100 percent charge, but it’s actually not ideal for the battery.
According to Battery University, a website run by Cadex Electronics, a battery technology company, lithium-ion batteries should never be charged to 100 percent. “A lithium-ion battery doesn’t like to be fully charged,” Battery University’s CEO Isidor Buchmann says. “The maximum charge is about 90 percent, because that’s when the voltage peaks.”
The reason for this is that lithium-ion batteries are designed to have a slow discharge rate. When a battery is charged to 100 percent, it puts a strain on the battery and can reduce its lifespan. This is why it’s important to keep your phone charged between 20 and 80 percent.
It’s also important to note that leaving your phone plugged in after it reaches 100 percent can cause the battery to overheat. This can damage the battery and reduce its capacity. To avoid this, unplug your phone once it reaches 100 percent.
In addition to keeping your phone charged between 20 and 80 percent, it’s also important to avoid charging it too often. According to Apple, you should charge your iPhone only when the battery drops to below 50 percent. This will help keep your battery healthy and extend its lifespan.
In conclusion, it’s important to keep your iPhone charged between 20 and 80 percent for optimal battery life. Charging your phone to 100 percent can strain the battery and reduce its lifespan, so it’s best to avoid it. It’s also important to avoid charging your phone too often, as this can also reduce its lifespan. By following these tips, you can ensure your iPhone’s battery life lasts as long as possible.
