The meaning of 'Saft' (juice/power) is immediately clear from context. Words like 'trinken' (to drink) or types of fruit point to a beverage, while 'Akku' (battery) or 'leer' (empty/dead) refer to electricity.

I like drinking a glass of apple juice in the morning.
To specify the type of drink, 'Saft' (juice) is very often used as the second part of a compound word. The first part is usually a type of fruit or vegetable.

The use of 'Saft' (power/juice) for electrical energy is very colloquial. You often hear and read it in informal conversations, but not in formal texts.

After the argument, she simply left him to stew in his own juices.
For the colloquial meaning 'Strom' (electricity/power), there are typical formulations such as 'der Saft ist alle' (the power is gone) or 'keinen Saft mehr haben' (to have no power left).

Without electricity, the whole apartment has no power.

Strom is the neutral term for electrical energy and works in practically all relevant situations. Saft can mean the same thing colloquially, but it sounds casual and is not appropriate in every context. In factual statements, Strom is therefore the better choice.

His friend says casually: “The TV isn’t getting any power.”
Der Techniker stellt fest: „Der Fernseher bekommt keinen Strom.“
The technician determines: “The TV isn’t getting any electricity.”
