One of the biggest mistakes iPhone users make is incorrectly charging their phone’s battery. Believe it or not, there’s a right and wrong way to charge your device and, as Yan explains, these four battery mistakes can ruin your phone.
1. Don’t let your battery die
“Previously it was a good practice to let your battery fully die before charging because they used to be nickel-based,” Yan says. “But with today's lithium-based batteries, it is better to keep it charged than to do a ‘deep charge’ every once in a while. As a result, it can reduce your battery health and charge cycles.”
2. Don’t charge It full
“Keeping your phone fully charged to 100% is not a good practice,” Yan says. “Pushing your phone to extremes in either direction will cause wear and tear on the battery since it only has a finite number of charge cycles. A battery works best when kept between 40 and 80 percent.”
3. Don’t charge it overnight
“Don’t charge your phone overnight,” Yan says. “It may seem convenient and valuable to plugin when it’s time for lights out, but ever-changing your phone will heat it and can kill the battery quicker.”
4. Don’t use a battery backup case
“A phone case having a battery backup may seem handy,” Yan says. “But heat is terrible for a battery, and a phone case that doubles as a charger are both going to emit heat itself and cause the battery to warm up while charging. This will heavily damage your phone's internals and battery too.”
