APK Description:

Simple Battery Graph displays an interactive graph of battery level.
You can measure how much energy is consumed/charged per hour.

*** If the graph is not updated, please disable the battery optimization for this app by the Android settings. You can open it from the menu of this app. ***

How to use:
- Drag on graph to scroll
- Pinch in/out on graph to change time-axis
- Drag green label on the bottom to change measurement period
(Thick short green line indicates actual recorded point which is automatically chosen nearest point from thin green line)

Battery level is recorded for only latest 10 days.
A sine wave graph is generated as a sample at the first startup and it will be removed after 10 days.

I have confirmed this app works on the following devices:
- Essential Phone PH-1 / Android 10
- Xperia 1 / Android 9
- Nexus 6 / Android 7.1.1
