I present you Ampere application through which you can get several information about the battery and temperatures as well as the power of the charger and the intensity of the electric current and voltage.


 With this app you can for example search for an optimal charger/USB cable combo.
The app is not meant to be mA accurate. It is only good for evaluate which Charger/USB cable combo is good for you.
Background info: The app measures the battery charging/discharging current. If your phone is not connected to a charger, you see the discharging current which is negative. Now, if you connect a charger then the current what the charger gives will be used to supply your phone and the remaining power will be charged into the battery.
If your phone consumes 300mA without a charger connected, then a 500 mA charger will charge your battery maximum with 200 mA current.







You may through the latter cable experience and charger and compared the result if you have more than charger, for me I was surprised by the result obtained by Laket you use the tablet device charger firm in my it would be better and faster to charge the phone, but I found that the phone charger is stronger than shipping tablet .

Technical info: The displayed current is an average value from 50 measurements minus the 10 upper values and the 10 lower values. The displayed current can be shaky or unstable or even just zero which means, that the Android system provides such unstable values. Some phones, like the Nexus 4 reports such unstable wide spreading readings when charged with a low current charger (e.g. 500mA), that even the average value is just a joke.

Notice: The app works on Android 4.0.3+ devices. Not every device is supported because there are devices which lacks an appropriate measurement chip (or the interface) and they can not be supported at all.
