Smartphone batteries have different charge cycles. How one uses a smartphone and how one charges it affects the battery life in a big way. By not letting the battery drain completely, periodically, is a common error that many smartphone users make and that reduces the battery’s ability to hold charge and also throws out the calibration. Battery management tools focus on battery optimization and how long the battery will last, and largely help in keeping the phone’s battery healthier for a longer duration. AccuBattery is a unique battery management app which sheds light on the overall working and health of a smartphone’s battery. It is developed by a Dutch start-up called Digibites and is available for free on Google Play Store.

What is draining the battery?

Unlike default battery tools available in most Android smartphones, AccuBattery takes into account the processes running in the background to draw an estimate of how long a phone’s battery will last. Users can see the battery used when the screen was on, when the screen was off and when the phone was in deep sleep. Deep Sleep is a power-saving mode and should be ideally active every time the phone’s screen is off. Even after the screen is off, the phone’s software runs processes or syncs data in the background, draining battery without the user’s knowledge.

This tool gives users a more accurate idea of how long their phone can last without charge in different usage conditions.

Wear and tear of battery

The option to find out the wear and tear incurred by the phone’s battery is another key highlight of AccuBattery. Available in the app’s health section, the feature shows the estimated battery capacity in comparison to the battery’s originally designed capacity (for example, 3000mAh). Users can actually see the life cycle of the battery and how it deteriorated day by day. Charging a phone’s battery too much actually causes the wear.

The history section shows the number of times users charge their phone along with the duration of the charge. This helps users keep track of how the phone’s battery actually behaves when it’s being charged and when it is in use.

The app has an in-built alarm which sends a notification after the phone’s battery is charged enough. By default, it sends the notification after the phone is charged 80% as charging beyond 80% is bad for the health of the battery. However, users can modify the exact percentage at which they want the alarm to prompt them to take the phone off the charger.

Is the charger causing the problem?

In case one borrows a colleague’s charger who uses some other phone with a different battery size, the apps’ charging section will show the average charge speed, temperature, charge current and the time remaining for a battery to charge fully. Every charger is different, and using a high-voltage charger can actually damage the phone. This feature can help users identify if the charger is good for the battery or not.
