Ampere (Android application) (2025.05.03)

With the Ampere Android application, you can test/measure the charging and discharging status of the battery of your device.

This app earlier helped me to confirm that there was a problem with the previous charging cable or adapter, because the charging was very slow, and this app also helped me to select a good cable and a fast charger.

Today I ran a few tests again on my Motorola Moto G22 (Android 12) smartphone.

Discharging test with battery saver mode on, and with 100% brightness level.

In this case, the minimum consumption was 270 mA, the current (at the time of the screenshot) consumption was 350 mA (this was the average too), and the maximum consumption was 860 mA.

Discharging test with battery saver mode on, and with 0% brightness.

In this case, the minimum consumption was 140 mA, the current (at the time of the screenshot) consumption was 180 mA (this was the average too), and the maximum consumption was 290 mA.

Charging test with a fast charger, but in a solar powered 230 Volt system (with a 12 Volt <> 230 Volt inverter).

Nowadays I live in a tent in the rocky semi-desert, and nowadays I do not have access to normal electricity, so currently I cannot do normal charging tests.

During this short (few minutes) test, the minimum charging was 1000 mA, the average charging was 1150 mA, and the maximum charging was 1190 mA.

The solar system this time ran from the battery, because I did this test in the evening (after sunset).

Maybe it would have gave different values, when the solar powered system would have input from the solar panels.

Or maybe not.

And probably it would give different values, if I would plug in the charger into a normal socket with traditional electricity.

Probably the charging would also be faster.

Either way, currently I am satisfied with the current charging cable and adapter of my smartphone.

Usually it charges the 5000 mAh battery of the smartphone from 0% to 100% in one or two hours.

And all in all, I think that the Ampere application is useful/helpful.

If anyone is reading this, then I hope that you also find the Ampere application useful/helpful.
