Mengapa

Devices nowadays have built in batteries that aren't easily replaced. Normally one has to bring the device to service facility for them to disassemble the device, replace the battery and rebuild the device. This takes devices away from users and it cost some money. The alternative is to take care of your battery so it can last as long as possible.

Bagaimana

Modern batteries have greater degradation if they are charged to 100% or discharged to 0%. Ideally if the battery is kept between about 20% and 80% it has a lot slower degradation. At the same time charging is faster in this middle battery level range to keep battery degradation to a minimum.

This app

Unfortunately devices don't allow developers to control it's charging limits. The next best thing is an alarm that notifies the user when to connect or disconnect a charger. This app is a simple alarm that triggers when battery level drops bellow or charges above set levels. The goal is to have as lightweight app as possible so that it doesn't use unnecessary resources.

There is no gathering of data and therefore no predictions on how long the battery might last. It's just a simple battery alarm that makes some noise and vibrates when battery level triggers it. There are a good system battery app and other apps on this platform if you want graphs, predictions and other nice things.
