If you want to charge your smartphone faster, put it into aeroplane mode, as this significantly reduces the battery usage.
Is a toy broken - or is the battery just dead? Drop the battery from a couple of inches above a hard surface to see if it bounces. A fresh alkaline battery will land with a thud and fall over because it contains gel which absorbs the bounce. A dead battery will give a little jump and rebound off a hard surface because the gel has turned solid.
In the lift and in a hurry? Send it to the floor you want without stopping by first pressing the 'close doors' button, keep pressing it while you push the button for your floor, then keep both buttons pushed in until the lift starts moving. (Firefighters and police love this one.)
If some joker pushes all the lift buttons, simply press each button twice to cancel the floor stop.
Leave your computer screen gleaming by wiping it with coffee filter paper - it's lint-free (meaning it doesn't give off fluff), so there will be no dust left stuck to the screen.
Stop your laptop from overheating and having to use its battery-draining fan by placing it on top of a couple of open egg boxes. This will ensure your laptop gets plenty of air flowing around it.
Tights to the rescue
If you drop a tiny object - earring, sewing needle, watch screw - on the floor and can't see it, fasten a pair of tights over your vacuum cleaner nozzle with an elastic band, then run it over the floor where you lost it. It will be sucked safely on to the tights.
Microwave a bit whiffy? Put half a lemon into a jug of water, microwave it until it boils, then switch off and leave for a couple of minutes while the steam works its magic.

Looking for cheap flights online? Make sure you delete the airline's cookies (small files that websites put on your computer to store information) - the website keeps a count of how many times you've visited it, spots how keen you are and ups the price.
How to delete them depends on which internet browser you use, but it can usually be done via the tools or settings menu - look for privacy settings or temporary internet files.
Get the most out of that last sliver of soap by sticking it with water to a fresh bar.
Make razors last longer by blow-drying them after each use. Eliminating any residual moisture prevents the blades from oxidising and becoming blunt.

Lost your corkscrew? Avert disaster by holding the wine bottle upside down between your knees and hitting the bottom with your shoe. Gradually the cork will emerge, bit by bit.
Turn a cheap bottle of plonk into something more palatable by whizzing it in your blender for about 30 seconds - this will aerate it and allow the flavours to develop.
To hull a strawberry quickly, push a drinks straw from the tip of the strawberry up to the stem.

To separate an egg yolk from the white without bursting it, crack the egg into a bowl, take a clean, empty plastic bottle without its cap, squeeze it and place the mouth of the bottle on top of the yolk. Release the bottle's sides and the yolk will be sucked into it.

Improve your roses by burying strips of potassium-rich banana skins around the base of the plant once a month. This will feed your rose and help keep it disease-free.
