iPhone 5 Charges only at certain angles?

My Iphone 5 charges only when the lightning cable is pulled to a certain direction. It's the same way with two offbrand chargers. It works fine with a friend's OEM charger that came with their iphone 6 however. Both of my chargers worked fine for several months while I was on a trip, but have suddenly stopped working at the same time. I'm wondering if this is because of the IOS update that stops non MFI chargers from working? I cleaned out the port, no lint, and if getting a MFI charger is the solution, do I need to order off the Apple website or is there any cheaper solution?

Edit: Just checked friend's iphone 6 with my chargers, her phone doesn't charge with mine unless its pulled to the one side as well.
