In the past, we were not able to do much with the phone's battery except for the basics: check if it was full or empty, and maybe get a warning if it was about to die. But today, you can do much more with your phone's battery. You can check the current level, get detailed information about it, and even set a goal for it.

We are talking about Fast Charge. It is an app that can monitor your phone's battery, check if it is full or empty, and if it is about to die. All you need to do is download it and set the parameters.

Fast Charge is not the only app that can do this, but it is one of the best ones. We will tell you about the others, but first we need to explain how this app works.

It is a simple app that has a few options that can be set. If you want to know the battery level, you need to choose 'Battery'.

Then you need to enter the number of milliampere (or the charging level, if you want to be more specific).

After that, you will see a graph that will show you the battery level. If it is full, you will see a message that will tell you so.
