People are only just realising you can use AAA batteries instead of AA in devices

People are only just coming to terms with the AAA battery hack that might save you going the night without a working controller. Watch below:

Scrambling around the house looking for some AA batteries, and all that's left are the AAAs in your TV remote.

The shops are shut, everyone's in bed and your mates have gone on to win their divisions game without you.

So if you aren't able to buy a new pair in time, there is one short-term fix that people are only just realising exists.

With a controller that takes AA batteries, you can temporarily use AAAs instead - under one condition.

As shown in the clip above, you'll need a sheet of aluminium tin foil and if you wrap it around your AAA batteries, you can basically increase the length of the battery so it reaches the connector.

Since AAs and AAAs use the same amount of voltage, the new, longer battery matched with the foil, acts as a short term fix until you can get your hands on a fresh pair.

Just to reiterate, the hack will only last a couple hours at best and you're eventually going to need to replace them.

If you've a bit of spare cash, it's always worth investing in a rechargeable battery pack to avoid such anguish.

Commenting on the news, one shocked viewer said: "This should be in journal of physics."

Another added: "Gamers been knew about this struggle."

Someone else revealed: "My Xbox controllers used to be stuffed w foil."

He says: "In General, turn off Background App Refresh. And in Motion, turn on Reduce Motion and turn off these two."

Motion can be found under the Accessibility option in Settings.

And by 'these two', he means to switch off the toggles next to Auto-Play Message Effects and Auto-Play Video Previews.

The next step is to go to System Services. To find this, you need to go to Settings, then Privacy and then click on Location Services.

You then need to scroll down all the way to the bottom until you see an option for System Services.

After that, turn off Location-based Apple Ads - if that option is there on your device - iPhone Analytics, Routing & Traffic and finally Improve Maps.

And that's that.
