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

Ratings and reviews

As it says on the tin, this is a simple app that shows your battery percentage over time. It does exactly that and very well. The only way to get rid of the ads, however, is to subscribe for £0.70 a month. This is way too high for an app like this. I would be happy to pay a fixed amount to get rid of ads but paying that amount per month for such a simple app is ridiculous.

On a pixel 4, the graph is just random data. It even thinks it's charging with three hours to go when in fact it's half discharged and hasn't charged for six hours. Update: It's gone from worst to best. After fixing the app's battery optimization setting, I see a nice graph where you can see just how your battery is doing and how good (or in my case, bad) your charger is. A pro version would be nice.

This seems to be a good example of the "Simple and effective" apps that I prefer. It is exactly what I was looking for to monitor my battery temperature. I recommend making it a widget with about a 1x3 graph.
