Used all over the place in Chronicle with the three main characters' telekinesis. Apart from the usual pranks they play, Andrew uses it to lift and maneuver his camera throughout the film, Steve uses it to shovel potato chips into his mouth, and (in a deleted scene) Matt uses it to stir his milkshake.
In Clockstoppers, the protagonist has vast time-stopping powers at his fingertips. He uses them to impress his date and pull pranks.
In the movie Dragonheart, as the former knight, Bowen, struggles with two sticks to start a fire to cook his meal, his newly befriended dragon, Draco, uses his fire breath on the pile of logs.
Johnny casually uses his flame powers to pop some popcorn in one of those expanding foil bags usually used for barbeque or camp cooking.
He once used it to dry himself after a shower.
Ben uses his Super Strength to make some freshly-squeezed orange juice without even removing the oranges from their mesh bag.
It also has Mr. Fantastic stretching the skin on his face to make shaving easier, and using his stretchy arms to either reload the toilet paper without having to leave the loo, or slide his hand under Ben's locked door to open it and check on him.
The second movie keeps up this trend with Sue using her power to make Reed's Blackberry invisible when he's ignoring her and Reed using his stretching ability to dance up a storm at his bachelor party. As mentioned in the comic section above, the Fantastic Four use their powers in this manner all the time, since the comic has a very domestic atmosphere.
Flubber: This quasi-sentient green goo can release enormous amounts of energy. What does he use it for? Cheating at basketball.
In Horsefeathers, Professor Wagstaff (Groucho) uses the telephone to crack nuts.
The title character of Jumper apparently uses his power of teleportation mainly to retrieve the remote without having to physically walk to it.
There's even an argument between two jumpers where one asks the other why he bothers to walk ANYWHERE when he can teleport.
James Bond is always using Q's fantastic gadgets for mundane (or just 'other') purposes. For example, at the beginning of Live and Let Die M and Moneypenny give Bond a watch containing a powerful electromagnet. Almost immediately after M and Moneypenny leave, Bond uses it to open the zippered dress of his latest 'conquest'.
Matilda uses her telekinesis to get books off the shelf.
The second Men In Black movie has Jeeves saying he used the exhaust from the Deneuralizer to make hot air popcorn.
One of the early hints in Mr. and Mrs. Smith that Jane Smith has hidden skills (as an assassin) comes when she fixes the way a curtain is hanging by balancing perfectly on a chair that is standing on only one of its legs.
John also uses this trope to verify his suspicions that Jane is indeed an assassin—he pretends to drop an open bottle of wine and by instinct Jane uses her better-than-average reflexes to save the carpet.
In the Mystery Science Theater 3000 movie, Tom Servo mentions that he uses his Interocitor, a device from the movie they're watching that can do everything from fire disintegrator rays to pilot spaceships, to make hot chocolate.
In Real Genius, Val Kilmer's character uses a sophisticated cutting tool to carve coin-sized slices of frozen nitrogen (which doesn't actually exist), which he uses to cheat the vending machine out of free soda.
It should be noted that this was actually a mistake in the movie as what he was using had the properties of solid dry ice(frozen carbon dioxide) but it was called liquid nitrogen (which as the name implies is a liquid). Using dry ice to cheat vending machines had been done.
Shaolin Soccer stars a martial artist who wants to teach people kung fu techniques that can help them with their everyday lives - for instance, parallel parking by pushing your car into place, or trimming a tree using Wire Fu jumping techniques. To gain publicity, he uses his skills to compete in soccer.
Anakin uses the Force (which is supposedly so mighty that the ability to annihilate a planet pales in comparison) to... make a Shuura fly to his girlfriend's fork. He notes that Obi-Wan would be quite upset if he saw him.
Obi-Wan casually uses the Force to retrieve a data module from a projector as he and Yoda are leaving the room.
Even Yoda is not immune. At the conclusion of his duel with Count Dooku, he uses the force to retrieve his walking stick which was near enough that he could have simply bent down and picked it up. Prior to this, Yoda takes his lightsaber from his belt with the Force.
In the roleplaying books, using the Force for mundane things moves you towards the Dark Side. Which is actually ironic as Jedi are far more likely to use the Force for mundane reasons in the movies. Sith are actually more conservative in their use of the Force as they are in hiding for much of the time and Palpatine is far too busy using the Force to see the future to worry about using it for mundane functions. There is also the fact that most Sith are in positions of power where they have servants anyway.
The Parr's homelife in a nutshell — especially Helen, who finds a way to apply her superpowers to nearly every household chore despite her oft-expressed desire to live a normal life. And, related to Power Perversion Potential, having an elastic body probably came in very handy during the pregnancies. (For that matter, a rubbery woman is the least likely for Bob to accidentally crush with his strength).
Inverted in one brief scene, when Helen realizes (much to her chagrin) that in spite all the cool stuff that she can do with her stretching powers...she can't seem to control the size of her butt.
The Sword in the Stone - Merlin's borderline Reality Warper powers are used to help "Wart" do his chores so Merlin can sneak Wart off for lessons. Though this inevitably backfires when Wart's guardians stumble upon this and ground Wart for quite some time.
Inverted in the case of telekinesis: most psychics in the film are barely capable of lifting coins a few inches above their hands, and mainly use their ability for party tricks... except for Cid, AKA the Rainmaker.
Gandalf in The Hobbit is seen using a small fire spell to light his pipe. He uses the same spell later on in the movie to much greater effect by turning pine cones into fire bombs.
In Pacific Rim, after Kaiju attacks have become a fact of life, enterprising scavengers have adapted accordingly, learning to harvest Kaiju parts for public use. Just for starters, Kaiju excrement is said to possess enough phosphorous in one cubic meter to fertilize an entire field.
In Sorcerer's Apprentice, Dave is trying to clean up his lab (an abandoned subway station) before his date with his Love Interest. Realizing he's running out of time, he uses magic to enchant a broom, a bucket, and a few other objects to do the cleaning for him. Naturally, it all goes out of control, flooding the place and nearly getting Dave electrocuted in the process. In fact, he's falling into the electrified water, as his master Balthazar comes back and freezes him in mid-air. Balthazar is not pleased.
Drake, Dave's Morganite counterpart, uses his magical abilities to be an illusionist.
At the end of Frozen, Queen Elsa uses her ice powers to entertain her subjects, making an ice-skating rink in summer. She's also implied to create blocks of ice to be regularly delivered to people's ice boxes.
