Experts warn – you are making a serious mistake if you charge your phone with a case

Even the most expensive and newest smartphone is no longer worth anything if the battery fails or does not charge properly. Sometimes it is not the device's fault, but your own. If your phone is wearing a case, charging can go wrong. Even smartphone manufacturer Apple warns against this.

Mobile phone battery: That’s why you should remove the case first

If you supply your smartphone with power while it is in its case, this can, in the worst case, lead to the battery overheating. Experience from the editorial team shows that charging with a wireless station, for example, can cause the device to become very hot (affected model: Samsung Galaxy S10e).

This can cause damage to the cell phone battery. The charging process can be delayed and the battery life can be reduced in the long term. Apple, among others, is aware of this and therefore specifically advises iPhone users against doing this.

This is what Apple recommends instead: “Charging your device in certain cases may generate excessive heat, which may affect battery capacity. If you notice your device getting hot while charging, remove it from the case first.”

Another problem: the charging process does not take place at all

The following is particularly annoying: If you don't notice that the plug no longer fits properly into the charging socket, you can stop the charging process without noticing. Because the missing contact means no current flows. If things go really badly, you plug your phone in to charge it overnight, and the next morning it is empty or even dead, as the editors' experience shows.

The case doesn't necessarily have to be of poor quality, but if it's thick and has a proper cutout, it can be difficult to tell with the naked eye whether the plug is actually properly inserted. Sometimes it feels like the plug is fully inserted, but in reality it's just the edge of the plug that's touching the edge of the case.
