If you are planning on getting a MagSafe charger for your phone, you must be thinking about the rumors of battery damage. The truth is, using a MagSafe charger can damage your phone’s battery life. In this article, we would be sharing some of the reasons why a MagSafe charger can damage your phone’s battery. Let’s dive in:

How a MagSafe Charger Can Damage Battery:

Overheating:

When your phone comes in contact with a MagSafe charger, there is little or no space between the device and the charger. Therefore, the main reason why you would see a reduction in your phone’s battery capacity is that the charger fails to prevent overheating. The MagSafe charger has a magnetic coil that is automatically aligned between the Magsafe charger and iPhone. Due to this alignment, the charging power is automatically increased from 7.5W to 15W under stable current conditions. However, this increase in power leaves no room for thermal sensitivity between Magsafe and iPhone built-in components. When your phone heats up, it causes irreversible loss of battery capacity. According to sources, the high-speed MagSafe charging of 15 W flows only the first few minutes of charging. The constant contact between the charging coil and the iPhone causes it to heat up and leads to battery loss.

Frequent Charging with MagSafe:

As we now know that using a MagSafe charger, your iPhone is heated more than usual. Thus, doing so for a long time can reduce the battery capacity level. The damage caused to your iPhone might not be drastic if you only use a MagSafe occasionally. However, if you put your iPhone on MagSafe for an overnight charge, the constant heat would keep it warm and cause no good to the battery.

Is cable charging a better option?

As we know that charging with a MagSafe is not “healthy” for your phone’s battery, charging with a USB cable is the only second-best option. USB-C cable also heats your battery as close to a MagSafe charger, so a USB-C cable is not the best option either. However, it is the second-best alternative when we have to choose between fast and battery-saving.

How can you prevent your MagSafe from ruining your battery?

Here are some tips that you can follow to keep your phone’s battery healthy:

If you have an iPhone 13, try charging it when then the battery is less than 50%.
If you feel that your phone is heated up more than normal, avoid charging it with a MagSafe or charging it all immediately.
Avoid using your phone while it is on charging.
Keep a check on the health of your phone’s battery and the health of your MagSafe charger as well.
Lastly, get your MagSafe Charger from well-known and qualified manufacturers.
