Doze Battery Saver is a free Android application developed by Chomic Software. It is designed to extend your battery life by hibernating apps when the screen is off, thus increasing the performance of your device. This app is perfect for those who want to prevent their device from draining the battery overnight while the screen is off.

By utilizing DOZE Battery Saver, you can expect only a marginal battery percentage loss overnight, ensuring that your device remains functional and ready for use the next day. The app effectively suspends the background activities of all applications when the screen is off, which helps conserve power until you choose to launch those apps again.

It's important to note that DOZE Battery Saver is mindful of critical apps like alarms and instant messengers. It ensures that these essential functions are not hibernated.  However, the app requires root access to provide its benefits.
