Enjoy the pleasures of face-to-face conversation. Look out the window of the tram. Do what humans did for thousands of years before the invention of the cell phone.If that’s not an option, first try to clean the charger port using canned air (follow instructions on the can) or a camera lens brush blower. If that doesn’t work, make sure your cable doesn’t have any breaks. If no easy fixes work, go to the Savyolovsky Market and head to the first floor of the computer building (IA, farthest from the metro station Savyolovskaya). There are several repair centers for every phone manufacturer. Putting a new port in an iPhone costs 1,000 rubles and takes 15 minutes. Service centers — i.e. stalls — for other brands offer about the same service for a comparable price.
