Is charging iPhone through Mac harmful?

The first thing users need to know is that charging an iPhone using a Mac does not pose any risk to the battery life or integrity of the device. In fact, both devices are designed to work together, and the Mac operating system, macOS, is compatible with charging and syncing from a user's iPhone.

Many people have the habit of charging their iPhone from their Mac.

Another important thing to note is that while charging is compatible, it will be slower than using a regular charger, especially if your Mac is running power-intensive tasks, such as editing video in Final Cut Pro or rendering scenes in Blender.

Another issue that can occur is that your Mac's battery will wear out more noticeably, as it uses its own battery to charge your iPhone. This can result in higher power consumption and in the long run, reduce the battery capacity of your laptop.

Additionally, charging an iPhone with a Mac for extended periods of time can increase the temperature of both devices, and the iPhone is more likely to be damaged since it has fewer temperature controls than a Mac. Finally, if you’re going to use this option, it’s best to use official charging cables and those that are Apple (MFi) certified to avoid problems.

What are the charging notes to ensure battery life?

Although batteries will lose performance over time, there are various ways to slow down this process to help your battery last longer. Here are some tips that users need to know to ensure longer battery life.

Charging your iPhone with a regular charger is still recommended.

• Don't charge your device fully every day: Device batteries operate in charge cycles, so it is no longer necessary to charge from 0-100% capacity, but to keep your device's battery between 20% and 80% to prolong its usage time.
• Perform a full charge cycle every now and then: To keep your iPhone battery in optimal condition, you should perform a full charge cycle at least once a month. This involves charging your iPhone to 100%, then letting it drain completely, and then charging it back to 100%. This essentially calibrates the battery completely and allows it to display the most accurate battery percentage.
• Cool environment: While charging, make sure your iPhone doesn't get too hot, as this can affect the life of your battery and the performance of your internal components. If you notice that any of your devices are getting too hot, disconnect your iPhone from the charger.

In short, occasionally charging your iPhone via your Mac won’t cause any significant issues. But to maintain optimal battery life and performance for both devices, you should use a regular charger whenever possible and only charge your iPhone on your Mac when necessary.
