Want to spend less time on your phone? Try this hack.

Much ado has been made about young people spending inordinate amounts of time on their phones, but in reality, people of all ages and generations struggle with smartphone addiction. We use our phones for everything these days, but the utilitarian use of them can quickly be overshadowed by the dopamine hits we get from social media, games, and other apps that are designed to suck us in over and over.

People can try to limit their screen time, but it's hard when our phones are something we legitimately need to use. It's a slippery slope from checking an email to answering a Facebook message to clicking on a video, and then we're off to the races. We can remove apps or use app blockers, but there's an even simpler solution that many people swear by: grayscale.

A simple switch in your phone's accessibility settings changes the phone from full color to grayscale, and for many people, that's all they needed to break the spell their phone had over them. When you open your phone and are met with a black-and-white screen full of apps, it does two things: 1) It reminds you that you're trying to use your phone less, and 2) It makes using your phone a whole lot less interesting.

The boring look is what makes it so effective; the idea is that our brains don't react to a grayscale screen the way they do to a brightly colored one. A 2023 study found that switching your phone to grayscale was "an effective strategy to reduce screen time and improve digital well-being," and people on Reddit have shared how much switching their phone display to grayscale has helped them:

"Recently, I switched my phone screen to grayscale and reduced the refresh rate to 60 Hz. The real surprise came when I looked up from the screen after a few minutes. Everything around me appeared way more vibrant, like in a radioactive way. It was like reality itself was so oversaturated that it felt surreal, almost cartoonish. For the first time in years, I can honestly say the world around me seems far more vivid and interesting than my phone screen." – EngarReddit

"Each time I apply grayscale on my phone, I feel less tempted to use it because it's so boring compared to the colors of our world. Our mind is highly influenced by colors (that's why you're more willing to eat a dish that looks vibrant and colorful compared to a shitty mess, even though they have the same taste)." – [deleted]

"Yes! I’ve only had it on for a few hours and everything “looks like 90s” everything is colorful again and normal and feels real like a haze has lifted." – Hot_Necessary_3305

"Yeah, grayscale my phone is the only thing that helped me curb my phone addiction. Now if only I know how to make a shortcut to it. Going all the way to accessibility to change it is a hassle. Sometimes I need to change my phone back for color required task and my eyes will get used to black and white eventually so I have to keep switching it on and off." – American_GrizzlyBear

"My phone automatically switches to grey scale every night at 10pm, helps to discourage scrolling at night." – m333ejm

"Turned it on and instantly found myself less interested in scrolling. I completely get what you mean by the world being more vivid, looking up after staring at a greyscale screen makes the colours jump out at you in the real world. I’ve setup an automation to have greyscale turn off when I open photos & the camera but for now, this is definitely what i’m using going forward." – QuitSplash

How to turn on grayscale in your phone settings

The grayscale option is usually under Accessibility settings. Still, how you get there will vary by phone make and model, and any instructions I share here may end up outdated, so a quick Google search for "How to turn on grayscale settings on iPhone/Android" is your best bet for figuring it out.

I found that setting a grayscale display on the iPhone wasn't terribly intuitive, and once I put it in, I realized how annoying it would be to switch back to color if I wanted or needed to. (Sometimes I want to see a photo in color, or I'm looking at a color-coded chart that doesn't work in grayscale.) After a little tutorial from a Gen Zer, I was able to set a toggle shortcut so that if I press the power button quickly three times, the color options pop up so I can switch back and forth quickly.

Most of us can use some hacks to help us break our phone and screen overuse, and the simpler, the better. Try the grayscale trick and see how quickly your brain loses interest. For many, it's nothing short of life-changing.

UCI doctoral candidate Mya Le Thai has developed a nanowire-based technology that allows lithium-ion batteries to be recharged hundreds of thousands of times.

There's an old saying that luck happens when preparation meets opportunity.

There's no better example of that than a 2016 discovery at the University of California, Irvine, by doctoral student Mya Le Thai. After playing around in the lab, she made a discovery that could lead to a rechargeable battery that could last up to 400 years. That means longer-lasting laptops and smartphones and fewer lithium ion batteries piling up in landfills.

A team of researchers at UCI had been experimenting with nanowires for potential use in batteries, but found that over time the thin, fragile wires would break down and crack after too many charging cycles. A charge cycle is when a battery goes from completely full to completely empty and back to full again.

But one day, on a whim, Thai coated a set of gold nanowires in manganese dioxide and a Plexiglas-like electrolyte gel.

"She started to cycle these gel capacitors, and that's when we got the surprise," said Reginald Penner, chair of the university's chemistry department. "She said, 'this thing has been cycling 10,000 cycles and it's still going.' She came back a few days later and said 'it's been cycling for 30,000 cycles.' That kept going on for a month."

This discovery is mind-blowing because the average laptop battery lasts 300 to 500 charge cycles. The nanobattery developed at UCI made it though 200,000 cycles in three months. That would extend the life of the average laptop battery by about 400 years. The rest of the device would have probably gone kaput decades before the battery, but the implications for a battery that that lasts hundreds of years are pretty startling.

“Mya was playing around, and she coated this whole thing with a very thin gel layer and started to cycle it,” said Penner added. “She discovered that just by using this gel, she could cycle it hundreds of thousands of times without losing any capacity.”

“That was crazy,” he added, “because these things typically die in dramatic fashion after 5,000 or 6,000 or 7,000 cycles at most. ”"The big picture is that there may be a very simple way to stabilize nanowires of the type that we studied," Penner said. "If this turns out to be generally true, it would be a great advance for the community." Not bad for just fooling around in the laboratory.

Since her discovery, Mya Le Thai has gone on to a successful career as the Principal Scientist with the Enevate Corporation,

While astronomer Carl Sagan would likely be the first to scoff at the idea of him being a fortune teller, the man certainly had a prescient way of looking ahead during his lifetime. Sagan was the original host of "Cosmos" back in 1980 and it became the most watched show in public television history. Few science communicators have been able to match his talent for stoking wonder about the universe and our place in it.

Shortly before his death in 1996, Sagan appeared on "Charlie Rose" and made a dire warning about how the average Americans' lack of skeptical, scientific thinking could lead to disastrous consequences.

Today, we can see the problems that are happening due to America's anti-science streak whether it's anti-vaxxers, conspiracy theories or climate change deniers. Sagan was right, America will suffer due to a lack a lack of scientific skepticism.

"We've arranged a society on science and technology in which nobody understands anything about science and technology, and this combustible mixture of ignorance and power sooner or later is going to blow up in our faces," he told Rose. "I mean, who is running the science and technology in a democracy if the people don't know anything about it?"

He then warned that our lack of critical thinking leaves us vulnerable to those who wish to exploit our ignorance.

"Science is more than a body of knowledge, it's a way of thinking," he says. "A way of skeptically interrogating the universe with a fine understanding of human fallibility. If we are not able to ask skeptical questions to interrogate those who tell us that something is true, to be skeptical of those in authority, then we're up for grabs for the next charlatan—political or religious—who comes ambling along."

Sagan believes that a democracy cannot function without an educated populace.

"It's a thing that Jefferson lay great stress on. It wasn't enough, he said, to enshrine some rights in the Constitution and the Bill or Rights, the people had to be educated and they have to practice their skepticism and their education," he says. "Otherwise, we don't run the government, the government runs us."

Part the problem we face in the present is that what constitutes education, including science and technology education, is being debated at the highest levels. Institutions of higher learning are undergoing attacks by the government, traditional education is being devalued by powerful parts of the political world, and positions that were traditionally filled by public servants with credentialed expertise are now being filled by political loyalists instead.

Critical thinking has also taken a beating. People believe themselves to be "critical thinkers" simply because they go against scientific consensus, but that's not how critical thinking and skepticism really work. When political ideologies take precedence over genuine scientific inquiry and investigation, we all lose out.

Some might even say we've already reached the place Sagan tried to warn us about. Of course, that's up for debate as well, but regardless, Sagan certainly seemed to have his finger on the pulse of humanity's tendencies. Hopefully people will heed his words and put science education in its rightful place as part of a thriving democracy..

A UPS driver on a phone call.

Certain professions have an inside look at the economy because they’re on the ground floor and see things change firsthand. For example, the advertising business knows that a recession is coming six months ahead of time, and realtors often get a good idea of how the economy is changing before the shock hits everyone else.

Delivery drivers are another group of people who can get a good idea of how the average person is doing. They have more packages to deliver when the economy is doing well and fewer when things take a turn for the worse. That’s why a TikTok by UPS driver Donate McCauley (@dontaymccauley) has so many views. After delivering Christmas packages, he thinks things are going well for most people at the end of 2024.

“I thought everybody was broke. I thought we were trending towards a recession, and y’all been complaining all year about finances, and y'all say that until Christmas,” the UPS driver said in a video with over 100,000 views.

“I see y'all actually do got money. And y'all making us pay, for every house got, like, 3, 4 packages. I'm loaded up,” McCauley continued. “Every day I'm going out with 400 packages on this truck, and y'all killing us, man, give us a break. But I thought you ain't have no money, though?”

Was the U.S. economy good or bad in 2024?

The post received many comments; some said they are having difficulty getting by this year, while others say they are doing pretty well these days. It’s another example of the lukewarm way that people have viewed the U.S. economy since the COVID-19 pandemic subsided.

“Broke as in it costing me a whole helluva lot more to live than it should. I will always have money for Christmas one way or another,” Lisa Marie wrote. “We’re using After Pay. I did LOL,” Juanita added.

“I have been saying this ALL YEAR. Every restaurant, every tourist attraction, special event, and retail store is PACKED most of the time in my small ‘poor’ city,” SteelersGirl wrote. “I said this to my husband a few weeks ago. Everywhere I go, people are buying stuff. Car dealership was packed last week, too. The economy seems ok,” Wiat What wrote.

Another delivery driver chimed in, and she shared McCauley's sentiment. “USPS here. I have been saying this for the last year,” ChicagoGirl wrote.

Did Americans spend more in 2024 on Christmas?

The confused delivery driver who says that people are saying one thing but spending in another tracks a pre-election poll. A survey taken in September 2024 found that 62% of respondents said the economy was weak, while 38% said it was strong.

Regardless of how individuals feel about the economy, the numbers don’t lie. 2024 was a strong holiday season for retailers. Visa says that spending is up this holiday season 4.8% over 2023. "This holiday shopping season, we’re seeing increasing consumer confidence as people sought out in-store experiences – and went online – to purchase gifts and celebrate the holidays with friends and family,” Wayne Best, chief economist at Visa, said in a statement. “This spending growth demonstrates the adaptability of both consumers and retailers and the overall strength of the economy.”


What will Christmas spending be like in 2025?

This year's Christmas season is expected to be less robust than last year's. Inflation, tighter credit lines, and tariff pressures mean that, according to Zeta, there will be a 27% drop in American shoppers looking to spend $1,000 or more during the holiday season. There has also been a 2% increase in those who say that they will spend less than $100 (34% up from 32%). The bottom line is that consumers will be more deliberate about their spending this holiday season, and more people will be seeking discounts.
