Yes, I did. The charge from the original charger charges at about 1% per minute. A full charge from 0% to 100% (without using the phone while charging) confirmed it. It took 1 hour and 40 minutes. Also, you can plug the phone in at any time and test it for yourself, it's always 1% per minute on the original charger. So, anyone testing other chargers should use THAT as their guide to see if a different charger is getting better results.
