Yep I agree. Definitely the cheapest option It cost $90 Australian for a 6S battery. I decided to buy a ex demo Mini4. It will take another 3-4 days for delivery. CheersBattery on the iPhone 6 is really cheap to get replaced i paid 40$ for a new battery in a 6s and decided to use it just for flying. Its runs everything fine and its weird but after the battery replaced it really seemed to bring the phone back to life speed wise it seemed like it had started to be sluggish and not the same as when a 6s was released but after the bew battery its like it was when new.. alot cheaper to do that
