Wireless Charger Test

The +12C Pro app lets users evaluate all types of chargers, both wireless and wired. The complete battery charging characteristics, charging rate, and battery life history are available with just a tap or two. Connect your phone to a charger, run a test, and then chart the results. It’s that easy.

Things you can do with the app:

* Record and chart battery charging time and charging rate

* Run tests on all types of chargers including wired and wireless chargers

* Run charging tests during sleep mode or active mode

* Test if your phone or charger is overheating

* Test the impact your phone case has on charging times and overheating

* Investigate battery life comparing historical charging records

* Discover how iOS 13 Optimized Battery Charging affects your phone

* Export charts in PDF and JPEG formats

* Import the charging data into Excel for limitless analysis

* Share and compare your results against other phones and tablets

* Test whether charging on a wireless charging dock or disk is faster

* Evaluate the health of your chargers

* Determine if your phone or tablet benefits from a higher wattage charger

* Identify the fastest wireless charger from a group of chargers

* Evaluate a used phone to test if the charger is still operating at factory rates

There is no simpler or more accurate way to inspect how your phone charges than with this app. The app uses patent pending methods to provide precise results. You will be surprised at how different your phone charges using different chargers and configurations.

Some charger test apps look only at a few data points. As the screenshots above show, this leads to dramatic errors. There are even some points where charging appears to stop. To truly evaluate a charger, the full charger record must be investigated, and in both modes of charging: sleep and active.

Wireless chargers are not the same even if the rated power is the same. Some charge substantially slower than others. Some chargers overheat, and then overheat your phone! Look at the example charging curves shown in the screenshots above to see how different chargers behave.

As a battery ages, the time to charge the last few percentage points increase dramatically. This is another unique way to look at battery life. Monitor this change over the life of your battery.

While the app provides significant charting capability to visualize charging results, some app users might want to dive deeper into the data. This is possible by exporting a comma, space, value (CSV) file that can be read directly by Excel or other spreadsheets and mathematical analysis tools. The sky is the limit on what can be studied once you have the data.

This app was developed as an aid in a 2-year study on phone charging and chargers. The developers were surprised with what they discovered. You will be likewise surprised and benefit from the knowledge gained through using the app.
