The problem with charging your Android device is that you notice that sometimes a charger will charge quickly and sometimes not so quickly. The science behind this is actually the quality of the USB cable and the amount of juice the charger is pumping, plus a number of other variables. The Ampere app is able to read through all that and give you the current amount of power you are receiving during charging, and the amount of discharge as well when not charging.
Pretty standard, actually – but because of the numerous makes and models of devices, and the way their software allows or restricts access to these kinds of data, it is difficult to pin down an app that will do all of these things. Ampere looks to be that app. It started as an app compatible to Android 5.0 devices only – now it will read data off any device from Android 4.0.3 or better.
There are devices that are not compatible with the app, and as a caveat, the developer has listed them out in the app’s description. Notably, the Samsung Galaxy S3 and a lot of HTC One devices are there, and the LG G3. This author is using an LG G2-F320S, and the app works like a charm.
The app is good for trying to figure out which cable and charger combo is best for your device. It’s also nice to have when you go out and buy a spare or replacement cable. Nice to know if the cable is up for giving you a good charge rate. Download via the source link below.
