Smartphone FAQs

1.  How do I know if I need to buy a wide-angle lens?  If you have an iPhone 11 or newer, you already have a built-in wide-angle lens.  For other phones, stand at the back of the court and face the court, seeing how wide the viewing angle is. If you can see the corners or of the court (at the outside of the doubles alleys, you probably have a wide enough angle). If in doubt, you can always order the lens later.
2. How’s the battery life?  This varies by phone manufacturer and by age of phone. My Galaxy Note 9 will film for an hour and half and still have 66% battery left. According to SwingVision, who uses only later-model iPhones, you should have 80% battery life remaining for a two-hour match.
3. How much storage do I need? We recommend a minimum of 10 GB.
4. Will it overheat? On a warm day in the direct sun, there’s a very good chance it will overheat. Some kind of shade, maybe like this one, will help tremendously.
