Your Case Might Cause More Harm Than Good
Depending on the case you’re using and where you live, it could cause more trouble to your iPhone than it’s worth.
The reason is that your iPhone’s case might cause it to get hot while you’re charging it. This might not seem like much, but if you constantly charge your iPhone at high temperatures, you can damage its battery permanently, which is way worse than dropping your iPhone.
If your case is actually making your iPhone warmer, it’s best to remove it. You can always find a different case to use, but it would be a better idea to charge your iPhone — and use it — without a case.
