How to watch the power consumption in Android with Ampere

If you are curious and you would like to know how much power your apps really consume the latest version of Ampere offers you a new way.

Ampere was until now also capable to monitor the current flowing in and out of the battery, but for this you needed to open the notification area. The latest version of Ampere goes a bit further and it shows you the current direct as little notification icon. In this way you can enjoy your Android apps, and the current is always presented on the top of the display.

Here is how to use:

1.) To use this feature, you need to have the PRO version. If you don't have, then you can buy it by pushing the key icon.

2.) Open the settings menu and enable the notification.

3.) That's all. After a few seconds the measured current is visible in the notification  bar.


4.) If you wish, you can also change the notification priority. In this way you can decide the position of Ampere's notification or make it invisible in the notification bar.

How it works

In the following picture you can see how it really works:
  • Upper part: The device was just switched on, but no app was started. It can be seen, that the discharging current is 200 mA.
  • Middle part: Google Maps was started and London was tipped in in the search area. The device switched on the GPS and downloaded the corresponding part of the map. This caused a high load and the discharging current increased, it was 720 mA.
  • Bottom part: The device was connected to a charger. The current is now positive because in this case the battery was charged. The charging current was 840 mA.

You can install Ampere from Google Play:
