About this app
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

I love this app. It's simple and allows inspecting any past period for battery drain. But for some reason on my Samsung S25 Ultra it doesn't show the app that was in foreground at any given moment. Even though I gave it usage access data. The behavior really varies between my devices. Is it possible to fix this?

I use it all the time, on several phones, to see how fast my phone is charging, how ast it is discharging , ... Simple, clear, accurate.

always worked well but suddenly a mess on my doogee s41 pro. random increases and decreases of the graph and it does not keep track of accu level. pity, as it is the only app that really draws a good graph over several days.
