Not being snarky, but a typical cell phone charger uses well under 10 Watts (3 or 4 Watts is typical). A typical window or hotel room air conditioner is probably close to 1000 Watts. The voltage supplied to the hotel might vary slightly from 110V (maybe a few percent). There is not really anything the hotel can do as a practical matter to limit your electrical supply short of turning off a circuit and then the outlet would simply stop functioning.
There are a few possibilities:
Local brown out, but you'd notice that with lights flickering and other appliances failing. Even with that the wattage/current draw of your charger probably wouldn't be impacted because it's so small.
Problem with the electrical outlet. It might be cutting in and out. It might be ground fault protected, it might be on a switch in the room, but then it would likely just stop supplying electricity altogether.
Problem with your phone or charger. Unfortunately for you it sounds like the phone and battery is probably the culprit.
