Can we use simple present tense here?

Question

Here I found the following sentence.

When you use your phone while charging, the battery is charging at a slower rate than normal to allow enough power for the ongoing usage.

Can I use simple present tense here? Because they are talking about what normally happens when we use phone with charging on. And simple present tense is used to describe facts.

When you use your phone while charging, the battery charges at a slower rate than normal to allow enough power for the ongoing usage.

Is the above sentence correct? Thanks.

Answer 1

You can certainly use the present tense in this context. There is no problem there.

However, your sentence is not well constructed. The implication, however unlikely, is that your are charging (around) rather than the phone. Simply adding it after charging resolves the problem.

You could also simplify your sentence without losing any meaning. As it stands, it is overwritten.

To write: When you use your phone while charging it, the battery charges at a slower rate (than normal) is quite sufficient. It's hardly necessary to spell out the reason although, grammatically, it's quite correct.
