Whether you are waiting for an important phone call but want to step out for a while, or you are wondering if you need to charge your iDevice before you head to the gym and use those exercise apps with music to boot, this app will ensure that you are well aware of your battery life at all times.
This app is a recent addition to the News section of the App Store, where it can be purchased for the nominal price of 99 cents.
Battery! (Calculator + Custom Themes) takes up a mere 0.1 MB of space on your iPhone or iPad. There are similar apps available but rather than using a personalized calculation based on your usage, these apps provide a general battery estimate based on your device type, neglecting factors such as temperature, "age," and model type, all of which significantly alter battery life.
This app works by prompting you to enter the number of minutes you usually get on a full charge. To find out the exact figure, the developers have detailed three different ways so you can choose your desired method.
Appearance and Calculations
When you've set up the app with all the required numbers, you will be able to enjoy a battery theme of your liking. There are 11 themes to choose from that allow you to customize the battery color, and you can even import your very own image to make the theme more pleasant.
This app will then show you the percentage of your battery remaining and update in increments of five percent. Alternatively, users can also choose to tap the Calculate button if they want to know the number of minutes left from that very minute, and the app will calculate it by rounding it off to the nearest per cent.
What's more is that this app can even help you detect a weak battery; a battery that is not performing as well as it should be based on your model type.
