Battery Alarm - Charge Alert is a free utility tool available on iPhone that helps users stop unnecessary charging and maintain a healthy battery. With this app, users can set an alarm to notify them when their device is fully charged, allowing them to unplug their device with ease.

One of the main features of Battery Alarm - Charge Alert is the ability to choose the preferred battery level for the alarm. Users can set the alarm to go off at 20%, 40%, 50%, 80%, 100%, or any other desired battery level. This ensures that users can unplug their device at the desired charge level and avoid overcharging.

Another useful feature of this app is that it runs in the background, even if the display is off. This means that users will still receive a reminder to remove the charger, even if they are not actively using their device. This helps to prevent overcharging and prolong the battery life.

Battery Alarm - Charge Alert also allows users to adjust the alarm volume according to their preference. This ensures that the alarm is audible enough to grab the user's attention, but not too loud to startle them.

For subscribed users, the app offers additional features such as no ads, fade in volume feature, and auto stop alarm. The fade in volume feature gradually increases the alarm volume, preventing any sudden loud noises. The auto stop alarm feature allows users to simply remove the charger to stop the alarm.

Overall, Battery Alarm - Charge Alert is a useful utility tool for iPhone users who want to maintain their battery health and avoid overcharging. It offers customizable alarm settings, runs in the background, and provides additional features for subscribed users. The app is free to use with the option to unlock premium features through an upgrade.
