Capacitors will lose their charge over time, and especially aluminium electrolyts do have some leakage. Even a low-leakage type, like will lose …
transformerless
An ideal capacitor never converts any power to heat -- all of the electrical energy that flows into an ideal capacitor eventually flows out of the capacitor as electrical energy. A real capacitor has small amounts of parasitic series resistance (ESR) and parasitic parallel resistance, so a small amount of the input power is converted to heat.
