Tech Experts Say This One Everyday Mistake Could Be Draining Your Battery

Daniela Sawyer, founder and business development strategist of  FindPeopleFast.net, takes the explanation even further by reminding us that an iPhone’s lithium battery gives the best performance when it’s around 50% charged. 

“Most people tend to charge their phones overnight, use them all day, and set their phones only when the battery level is below 10%,” Sawyer says. “The low voltage operation has a severely detrimental effect on batteries' life, and regular quiet voltage operation causes batteries' health to degrade, leading to faster drain and less standby time. The best way to maintain a healthy battery life is to keep it around 50% all the time.”

Although Sawyer calls this the “ideal situation,” if that’s can’t be attained, the middle way she says she chooses is to set a preferable range in which she tries her best to keep the battery charge level. “I try to keep my phone between 25 to 85% all the time,” Sawyer says. “Operating within this 60% range provides the best operating environment for the battery and the phone, leading to slow drainage and more battery life. Though most of the experts suggest keeping this range between 30 to 80%, I found this range perfect for me based on my personal experience. It provides the best combination of battery life and its health.”
