Hey, my nexus 4 will just switch off with around 50% battery life and won't turn back on unless I charge it

This is handled by the phone's circuitry. When the battery is fully charged it will cut off charging, and it won't resume again until after the charge has dropped a few percentage points (since li-ion batteries also don't like super shallow charging cycles). Leaving your phone plugged in is only destructive if either your phone or your charger is defective.You're not supposed to charge a li-ion battery past 100% for extended periods of time. Good way of ending up with a battery that doesn't hold a charge, excellent way in fact.
Weird. Unfortunately, unless you're the sort who's into opening your phone up and screwing around with its components, there's really only one thing to try: if you're on custom firmware, go back to stock. If you're on stock, do a factory reset. Beyond that, I think you're going to be stuck doing a warranty/insurance exchange.
