I've been having charging trouble since last November, but it's been getting worse and worse over time - at first unplugging and replugging the cable would fix things, but now it's gotten to the point where it takes around 5-10 minutes of plugging, unplugging, and wiggling in order for the Lightning cable to make a connection. And of course battery degradation means that I need to charge a lot more often than I did when the phone was new... I have the same problem on 2 different PCs (using 2 separate Lightning cables, of course), so I'm pretty sure it's not the cable that's the problem. My contract expires in April, so I just need the phone to hang on until then. Any tips?
