So I tested how long it takes to charge the iPhone 6+ from 0% to 100% using the 12w 2.4a iPad charger and it took exactly 2.5hrs. Definitely not speedy but certainly a lot faster than with the regular charger I know it easily took longer than 3hrs although I didn't time that..

I've been charging my iPhones using the iPad charger ever since the iPhone 4 and it's definitely faster than using the iPhone charger.
 
will this method eventually harm the battery?

No. All it does is charge the battery faster. iPhones/iPads have built-in circuitry that shuts down the incoming flow of electrons when the device is fully charged, so there is no increased risk of damaging the battery.
