Over the course of the year, experts at Which have been testing the latest tech products – and now they have revealed the “secrets” they have uncovered with Money.

Here’s what they found: 

Energy-saving modes on TVs make minimal difference to overall running costs. 

While they make very little cost difference, the energy-saving modes can make an enormous difference to picture quality, the consumer champion said. 

AI features in flagship phones vary significantly in how effective they are. 

Which? ran its own independent tests of AI photo-editing features on the Galaxy S24 from Samsung, the first manufacturer to bring out comprehensive AI features. 

Testers found the tech struggled to remove objects in detailed images and generate natural-looking content to fill the gaps. 

It’s better to keep your printer on standby mode

Testers said people were likely to fork out less than £1 on energy when printers spend most of their time on standby. 

“It’s better to keep your inkjet printer on standby rather than turning it on and off frequently as this is more likely to trigger a cleaning cycle that uses up ink,” Which? said. 

It also advised people to consider a tank or laser model or switch to compatible third-party cartridges to save money on printing. 

Wi-Fi 6 routers can save you money 

Which? found shoppers can save money by choosing Wi-Fi 6 routers, mesh systems and extenders, instead of the newer Wi-Fi 7 option.

“Although Wi-Fi 7 offers some of the fastest connection speeds yet seen, it’s pricier and you won’t reap the benefits if connected to devices that are not also Wi-Fi 7 compatible,” it said. 

Lisa Barber, Which? Tech magazine editor, said: “Which? tests thousands of products every year and tech products are an area where we’ve uncovered invaluable secrets that we want consumers to be aware of. 

“By taking our advice on board, consumers can save money and make sure they are getting the best performance out of their tech products.”
