The battery has always been one of the weak points of all mobile devices, especially after the arrival of smartphones and those giant screens. As the charging cycles go by, the battery life of our device is getting worse until the moment when we are forced to change the battery, a change that, although it is more expensive, is always advisable to do it in the official stores of the company, if we do not want to install any battery whose duration and operation may not be 100% compatible with our device.
Although before getting to replace the battery, we can try calibrate the battery of our iPhone to improve the operation of our device. But if once we have made all the appropriate checks we see that the battery continues to give us problems, we can choose to use the application Battery Percentage, available in the App Store completely free of charge since it has ads within the application, ads that are quite annoying. Through the jailbreak we can find several tweaks that allowed us to obtain the number of charge cycles as well as extra information about the state of our battery, but so far we could not do it directly from the App Store.
But Battery Percentage not only offers us information about the state of our battery and if it is necessary to change it, but also offers us information about our iPhone related to the CPU, GPU, memory, storage and traffic of our internet connection. But it also allows us to perform different tests to verify that our iPhone is working correctly. Among the different tests we can find one that allows us to check if we have any dead pixels on the screen, the operation of the camera, the speaker, the microphone, the earpiece and the volume button.
The application is no longer available in the App Store
