When Should I Charge My iPhone? | ZONSAN

2023-01-12 It's generally best to charge your iPhone when the battery is low (below 20%) and unplug it once it reaches 100%. This helps to prolong the overall lifespan of your iPhone's battery.

Li-ion batteries, the type of batteries that are used in most modern electronic devices, including iPhones, have a limited number of charge cycles. Every time you charge your battery, it goes through one charge cycle.

You'll want to avoid partially charging your iPhone repeatedly, it's better to let it fully drain and then charge it again to 100%, this way you'll be using less charge cycles and will prolong the battery life.



It's also important to avoid charging your iPhone overnight. If you charge it before going to bed and wake up with 100% battery, you are doing unnecessary charge cycles. Instead, it would be better to charge your phone just enough to last you until the morning, then charge it again.

Keeping your iPhone cool while charging can also help to speed up the charging process and to protect your battery health. Avoid charging your iPhone in direct sunlight or other hot environments.

It's also worth noting that newer iPhones have a feature called Optimized Battery Charging which helps to slow down the rate of battery aging by reducing the time that your iPhone spends fully charged. This feature can be turned on in the battery settings.
