Make Sure You’re Using the Right Charger
Since Apple doesn’t give out wall chargers with iPhones anymore, you need to find one for yourself. Even though you might want to get a cheaper option, you need to make sure you’re using the right charger. Your best choice is a first-party Apple charger or a charger that’s MFi (Made For iPhone) certified. But those aren’t your only options.
If you’re using another charger, make sure it delivers anywhere between 18 to 29 watts of power or more. Also, try to use a reputable brand that’s known for its quality products. Not using the right charger or charging cable can damage your iPhone’s battery in the long run or not provide enough power to last you through the day.
