Battery Manager

This app employs simple design to provide all battery properties in one glance. The following running parameters are provided in numeral and gauge views:
•current (available for devices with Android 5.0 or later)
•temperature
•voltage
•battery level

You can set alert thresholds for above quantities. When any measurement shoots over its threshold, device will beep to alert you to perform action on incidents such as overheating.

It also provides estimated time to fully charge or discharge based on present current consumption.

You may bring this app to background.

With logging function, you can monitor the battery and charger long term performance. The result is tabulated in HTML format and is saved in external public directory for later reference.
