New Month, New Reminder to Clear Your iPhone Cache

Why you should clear your iPhone cache and exactly how to do it in Chrome, Safari and Firefox.

Your iPhone is a handy pocket computer that lets you take the internet virtually anywhere you go, and just like every other piece of tech, it benefits from a little routine maintenance. Even browsing on the latest iPhone 14 Pro and Pro Max models might start to feel sluggish over time. Keep your iPhone’s browsers moving as fast as possible by clearing your cache every month — it only takes a few seconds.

Whether you use Chrome, Safari or other browsers on your iPhone, your cache builds up digital clutter over time. Clearing your cache gives the browser a new start, which can speed up your web surfing, even on iOS 16.3.1. (And if you’re trying to get your phone to run faster, try managing your iPhone’s storage.)

Your browser cache acts like a digital shortcut — it stores website data so your browser has a head start the next time you load up that page. In the short term, that helps speed up the process. But over time, the data stored in your cache can become outdated and no longer match what the site actually needs. If that happens, pages will load slower, and the formatting might be wrong.

That’s why clearing your cache can help: It gives sites a fresh start in your browser and frees up some space in your storage.

Website cookies are similar, except they store information about user data, rather than data on the website itself. Clearing your cookies gives you a chance to reset those preferences, which could improve your browsing experience. Note that clearing your cache and cookies will log you out of sites, which means you’ll have to log into them again and reset any preferences. But the upfront investment of that time can lead to a smoother experience down the road, and it can be a useful fix if you’ve recently changed settings that aren’t being applied properly.

Here are step-by-step guides on how to clear your cache on your iPhone based on the browser you use.

How to clear your iPhone cache in Safari

Safari is the default browser on iPhones, and you can clear your Safari cache in a few short steps. Starting with iOS 11, following this process will affect all devices signed in to your iCloud account. As a result, all your devices’ caches will be cleared, and you’ll need to sign in to everything the next time you use them. Here’s what to do.

1. Open the Settings app on your iPhone.

2. Select Safari from the list of apps.

3. Go to Clear History and Website Data.

4. Choose Clear History and Data in the pop-up box.

Then you’re set!

How to clear your iPhone cache in Chrome

Chrome is another popular browser for iPhone users. The overall process for clearing your Chrome cache requires a few more steps, and you’ll need to do things through the Chrome browser itself. Here’s how.

1. Open the Chrome app.

2. Select the three dots in the bottom right to open more options.

3. Scroll across the top and select Settings.

4. Select Privacy and Security in the next menu.

5. Then select Clear Browsing Data to open up one last menu.

6. Select the intended time range at the top of the menu (anywhere from Last Hour to All Time).

7. Make sure that Cookies, Site Data is selected, along with Cached Images and Files. Finally, hit Clear Browsing Data at the bottom of the screen.

How to clear your iPhone cache in Firefox

If you’re a Firefox devotee, don’t worry. Clearing the cache on your iPhone is pretty straightforward. Just follow these steps.

1. Click the hamburger menu in the bottom right corner to open up options.

2. Choose Settings at the bottom of the menu.

3. Select Data Management in the Privacy section.

4. You can select Website Data to clear data for individual sites, or select Clear Private Data at the bottom of the screen to clear data from all selected fields.

What happens when you clear the cache?

Clearing your cache removes the website data your phone stored locally to prevent having to download that data upon each new visit. The data in your cache builds over time and can end up slowing things down if it becomes too bulky or out of date. (My phone had about 150MB of data stored in Chrome when I checked.) Clearing that data gives sites a fresh start, which may fix some loading errors and speed up your browser. However, clearing your cache also signs you out of pages, so be prepared to sign in to everything again.

How often do I need to clear my cache?

Most people only need to clear their caches once every month or two. That’s generally the point when your browser will build up a cache large enough to start slowing things down. If you frequent a large number of sites, you should err on the side of clearing your cache more often.

McDonald’s KPop Demon Hunter Meals Include Bright Purple Nugget Sauce

The Derpy McFlurry mixes popping boba pearls and berry sauce into a soft-serve dessert.

McDonald’s has seen success with themed combo meals, including its holiday Grinch Meal. Now, the fast-food chain is capitalizing on Netflix’s Oscar-winning animated film, KPop Demon Hunters, with new upcoming menu items and both a breakfast meal and a lunch/dinner offering. Let’s hope you like the color purple.

The HUNTR/X Meal, named for the K-pop girl group in the movie, is a 10-piece chicken McNuggets meal that includes a medium drink and three special menu items.

Ramyeon McShaker fries come with a small bag of soy, garlic, sesame and spice seasoning, along with regular McDonald’s french fries. You sprinkle the seasoning into the provided bag, dump in the fries, shake it all up and eat.

The meal includes two new sauces for the fries and nuggets. Hunter sauce is a sweet chili sauce mixing notes of chili, garlic and pepper. But my favorite item on this new menu is Demon sauce, a bold mustard sauce with some heat and a bold purple color. There’s just not enough dark purple food out there.

There’s also a new dessert, the Derpy McFlurry, which blends creamy vanilla soft serve with berry-flavored popping boba pearls, served with a swirl of wild berry sauce. McDonald’s named it for the supernatural feline, Derpy Tiger, from the movie.

If breakfast is your bag, the new morning meal is the Saja Boys Breakfast Meal, named for the movie’s boy band.

It includes a Spicy Saja McMuffin sandwich, which is a sausage McMuffin with egg and a spicy Saja sauce, hash browns and a small drink.

Both meals come with a photocard for one of the bands and a Derpy card. The Derpy card includes a QR code you can scan to unlock online content about the film.

The full KPop Demon Hunters menu should be available at participating McDonald’s beginning March 31.

The McDonald’s Grinch meal (and its accompanying patterned socks) sold out quickly, so KPop Demon Hunters fans may want to mark their calendars and nab a meal when they are released.

Melania Trump Escorted by Talking Humanoid Robot at White House Tech Summit

The first lady shared the spotlight with the robot to promote the use of artificial intelligence in education.

An unexpected guest escorted Melania Trump at the Fostering the Future Together Global Coalition Summit on Wednesday: a Figure 03 humanoid robot.

During the event, the first lady pitched a future where AI-powered humanoid robots — presented as an idealized educator named «Plato» — provide students with personalized and instant access to human knowledge, including philosophy and art.

The Figure 03 robot is made by Silicon Valley-based robotics company Figure AI, which introduced its third-generation humanoid robot in October last year. The Figure 03 robot costs around $25,000, according to Forbes.

Figure 03 was designed for people to use in their homes, with demo videos showing it folding laundry, lifting eggs from a carton, using a washing machine and delivering drinks to its owners lounging by the pool. It was also shown in corporate use cases as a receptionist and a package deliverer. Using a proprietary AI engine called Helix, it can autonomously perform these tasks and respond to your voice commands.

The humanoid was seen walking slowly down the red carpet at the tech summit and then delivering opening remarks.

«I’m grateful to be part of this historic movement to empower children with technology and education,» the Figure 03 humanoid robot said. It then said «welcome» in various languages.

The first lady later said that AI-powered humanoid robots could exist in children’s homes as an aid to their education to «boost analytic skills and problem solving and adopt in real time to a student’s pace, prior knowledge and even emotional state.»

The two-day summit is hosting leaders from 45 nations and 28 technology organizations, and is intended to «empower children through education and technology,» according to a White House statement. Guests included representatives from tech giants such as Google, OpenAI, Microsoft and AI data analytics company Palantir.

The summit is part of the first lady’s Be Best: Fostering the Future initiative, which aims to help children learn using advanced technology. It was introduced in 2018 as an awareness campaign aimed at combating cyberbullying and helping children affected by the opioid crisis.

US Education Secretary Linda McMahon spoke about AI being one of the Department of Education’s main priorities on the first day of the summit.

«If we’re able to scale these resources effectively by investing in AI infrastructure and training, we can offer expert instructions across countless fields, to hire volumes of people at a fraction of the cost,» McMahon said Tuesday at a round table meeting.

According to McMahon, the Department of Education has already dedicated millions of dollars in grants to support the use of AI in schools.

The event follows criticism of the Trump administration’s 2025 executive order to dismantle the Department of Education. While the Department of Education hasn’t been officially abolished, it has undergone significant policy changes, funding cuts and workforce reductions.

The introduction of a humanoid robot at the summit sparked significant backlash among many who are wary of the technology’s role in the classroom. Critics took to social media to voice concerns that these machines could eventually replace teachers, stripping the education system of essential human connection, and leading to increased layoffs and cost-cutting.

On one Huffington Post Instagram post featuring the robot, commenters expressed deep skepticism, with one user sarcastically noting, «Nice, getting rid of educators in favor of a robot,» while another flatly rejected the concept, stating, «No, I don’t want to imagine a world with emotionless robots educating our children.»

The White House did not immediately respond to a request for comment.

Nintendo Dropped a Switch 2 Update With a New Mode You’ll Want to Turn On Immediately

This new feature is one of the best yet.

A new firmware update hit the Nintendo Switch 2 last week. Among the multitude of small changes is a new feature that will give Switch 1 games a notable upgrade.

Version 22.0.0 for the Switch 2 went live on March 16 and is available for download to the console. The big new feature in the update was Handheld Mode Boost, which will give Switch 1 games a visual upgrade when played on the Switch 2 in handheld mode.

[Nintendo Switch 2 System Update]
Version 22.0.0 adds «Handheld Mode Boost». This will make Switch 1 games think that they are in TV mode even when in handheld.

What does Handheld Mode Boost do?

Even though the Switch 2 supports backward compatibility with almost all Switch 1 games, there was an issue. The Switch 2 has a higher resolution screen: 1080p versus the older hardware’s 720p. When playing a Switch 1 game on a Switch 2 in handheld mode, the graphics looked blurry and jagged.

When enabled, Handheld Mode Boost makes a Switch 1 game act as if it’s docked, so it displays 1080p at 60 frames per second. This will give the visuals an immediate upgrade.

How do you enable Handheld Mode Boost?

Handheld Mode Boost has to be turned on to see the effect, and it takes a few steps:

Select Systems Settings from the Home menu
Select System
Select Nintendo Switch Software Handling
Enable Handheld Mode Boost

Is there a downside to enabling Handheld Mode Boost?

A user on Reddit tested the mode to see how it affects the Switch 2’s battery life. The test used Doom Eternal for the Switch 1 with and without Handheld Mode Boost. The test showed that the battery life decreased from 5 hours, 5 minutes to 3 hours, 43 minutes. That’s a 27% drop and should be taken into account when using Handheld Mode Boost.

How do I upgrade my Nintendo Switch 2?

If you have Software Auto-Updates enabled on your Switch 2, a pop-up window should come up whenever you start a game. If not, head to System Settings and choose to update the console from the menu.

What other features were added in version 22.0.0?

Handheld Mode Boost was the main star of the new firmware update, but there were a slew of other changes.

Changed the on-screen text and animations when you load a virtual game card in the HOME Menu.

Added the ability to save notes about friends on your Friend List. The note content is not displayed to friends.

Added the ability to invite friends to GameChat rooms you’re participating in. Some friends may not be able to be invited, such as supervised accounts.

Friends who haven’t finished GameChat’s initial setup can now be invited to GameChat. Some friends may not be able to be invited, such as supervised accounts or those who haven’t used a Nintendo Switch 2.

Added the ability to rewind 10 seconds/advance 10 seconds with the ZL and ZR Buttons when watching a full-screen video in News or Nintendo eShop.

Added the option to add the following data to «Automatic Uploads» from Album.

Text-to-Speech, under Accessibility, can now read the text in Album and during first-time setup.

Added the ability to see the breakdown of storage capacity by data type for the system memory and microSD Express card.

Added the ability to perform an audio test when «Linear PCM 5.1 Surround» is selected for TV Sound in Audio.

When Airplane Mode is activated, the previously set preferences for Bluetooth, Wi-Fi or NFC while in airplane mode will be saved and applied.

Added the ability to individually enable or disable Bluetooth, Wi-Fi or NFC during Airplane Mode from the Quick Settings.

Added the ability to see a notification in the Nintendo Switch Parental Controls smart device application when the Parental Controls PIN is input successfully on the console. This can also be set up to be a push notification to your smart device.

General system stability improvements to enhance the user’s experience.
