Your iPhone slows down over time, but here’s how to speed it back up

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

If your iPhone’s feeling a bit slower than usual, it could be due to a number of causes. But if you notice it sluggishly moving from app to app and struggling whenever you open a new browser tab, it’s probably time to clear your phone’s cache. You can do it in a few quick steps, and the trick might save you from having to spend money on an iPhone upgrade (unless you’re pumped about the iPhone 13). You can also manage your iPhone’s storage to help it get back up to speed.

Typically, visiting a website requires your phone to download information like photos, banners and other data. To help speed up that process, most internet browsers will store some of that data in a cache so it’s easier to retrieve. Think about it like storing a 24-pack of beverages in your fridge so you don’t have to trek to the grocery store every time you want a drink. In small doses, it’s convenient.

Things become less convenient when your browser’s cache gets outdated and the data being retrieved no longer matches the data actually being used on the website. The result? Slower load speeds and wonky website formatting. 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.

Note that clearing your cache will sign you out of sites you’re currently logged into. Still, it’s generally worth that mild inconvenience every now and then to keep things moving quickly.

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 cache in a few short steps. Note that, starting with iOS 11, following this process will affect all devices signed into your iCloud account. As a result all your devices’ caches will be cleared, and you’ll need to sign into 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. Scroll down and select Clear History and Website Data.

4. Confirm your selection in the popup 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 down and select Settings.

4. Select Privacy 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 more options.

2. Select Privacy in the next menu.

3. Select Settings at the bottom of that menu.

4. Select Data Management.

5. 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. (My phone had about 150 MB 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 into everything again.

How often do I need to clear my cache?

Most people don’t need to clear their caches more than once every month or two. That’s generally the point where 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.

Six Flags shares decline following deadly roller coaster incident

One person died and several others were injured in an incident involving the Goliath roller coaster at Six Flags Over Georgia, according to reports.

Shares of Six Flags Entertainment declined more than 16% Tuesday following a deadly roller coaster incident at one of its amusement parks in Georgia.

One person died and several others were injured Monday in an incident at Six Flags Over Georgia, according to a statement from Georgia’s Cobb County Board of Commissioners. The board’s chairwoman, Lisa N. Cupid, said that county authorities are working with Six Flags and other partners in the investigation.

According to reports citing local police, the incident occurred on the Atlanta-area park’s 200-foot-tall Goliath roller coaster shortly before 4 p.m. Monday. Riders were later seen being evacuated from the roller coaster after it stopped near the top of the ride, according to the report.

Witnesses told a local news station that they saw a man fall from the roller coaster and strike the ride several times.

In a statement to ABC News, a Six Flags spokesperson said it is cooperating fully with the investigation and had temporarily closed similar attractions across its parks.

Six Flags did not immediately respond to CNBC’s request for comment.

Tuesday’s decline is on pace to be the stock’s worst day since August and puts shares at their lowest level since December 2009. Shares have now fallen by more than 50% over the past year.

French supermarket fridges get hacked, heating to 122°F and sparking fires

Hackers targeted hundreds of French supermarkets in a large-scale cyberattack, causing refrigerators to overheat, spoiling food, and sparking fires.

Hackers targeted hundreds of French supermarkets in a cyberattack that reportedly caused refrigerators and freezers to overheat, spoiling food and sparking fires.

Fridges at French supermarket chains Carrefour, Monoprix, the Les Mousquetaires-owned Intermarché, and Coopérative U, among others, all saw fridges heat up to as much as 50 degrees Celsius (122 degrees Fahrenheit) overnight, Reuters reported Monday.

Coopérative U’s CEO, Dominique Schelcher, confirmed that cyberattacks had affected “refrigeration production facilities of several stores.”

“Attacking equipment that is essential to the preservation of fresh products and the food supply of the French people is extremely serious and unprecedented. It is unacceptable,” Schelcher said in a LinkedIn post.

CNBC has reached out to Carrefour, Monoprix, Intermarché, Coopérative U and E Leclerc for comment but did not immediately hear back.

Felix Aime, a senior cyberthreat intelligence analyst at Sekoia Threat Detection and Research, said the attack affected several European countries, including Spain, Portugal, Poland, Germany and Belgium, according to the Reuters article.

“I strongly condemn the cyberattack targeting food products at @intermarche @CooperativeU @Leclerc,” European Commissioner for Agriculture and Food Christophe Hansen said in a post on X on Monday.

“Food security requires more attention at all levels. Because the weaponization of food has become a reality.”

AI enhancing cyberattacks

Les Mousquetaires said it was expecting the damages, which affected around 180 stores, to reach “several million euros in losses,” in an email to CNBC.

It said some fresh and frozen food displays have been out of service after the cyberattack affected one of its service providers responsible for managing refrigeration systems inside some stores.

“Intermarché and Netto have taken all necessary precautions to remove and dispose of any affected products as quickly as possible, to ensure consumer safety,” the Les Mousquetaires spokesperson said. “In some stores, the overheating of equipment resulted in smoke, but no fires have been reported.”

They’re now awaiting findings from a court-appointed bailiff and insurance experts to get more precise figures on damages.

This comes amid a broader wave of cyberattacks and cybercrimes, which experts are warning are being enhanced by artificial intelligence. British online fashion retailer Asos experienced a cybersecurity breach last week which revealed some customers’ personal information.

Meanwhile, a small power plant in the U.K. was shut down for four days in July after a cyberattack which was suspected to be linked to Iran.

Interpol’s global chief information security officer, Bjorn R. Watne, recently told CNBC that AI can be used to target multiple victims at once, and is increasing the scale and speed of cyberattacks. “It’s an evolution and not a revolution.”

Correction: Bjorn R. Watne is global chief information security officer at Interpol. An earlier version misspelled his name.

Apple releases HomeView smart home hub with screen as showcase for Siri AI

The iPhone maker also announced the new Apple TV 4K and HomePod Mini.

Apple on Tuesday announced a new home hub called HomeView.

Apple said the device with a 7-inch screen was designed to be mounted on a wall or placed on a table. It’s designed for multiple people in a household, and will recognize the user by their face to display pertinent information. It starts at $299 and ships on Nov. 13.

Tuesday’s launch event is the second under new CEO John Ternus, who took over from Tim Cook in September. Last month, Apple announced new models of its most important product, the iPhone, including a foldable model called the Duo that retails for nearly $2,000.

Apple also announced new Apple TV and HomePod hardware on Tuesday. The new Apple TV 4K costs $299 and has a redesigned remote that can play a sound if it is lost. Apple’s HomePod Mini speaker comes in new colors and costs $149, a slight increase over its previous $129 price.

The products announced Tuesday are less critical for Apple than the iPhone, and investors remain focused on iPhone sales, but the accessories were positioned on Tuesday as a showcase for the company’s new Siri abilities released last month.

Apple said that HomeView features Siri AI, which can answer a broad range of questions. Users will be able to converse with Siri, and their conversations will continue on their iPhone or iPad. It has a built-in speaker for playing music.

“It recognizes your face to shift from a household screen to your own experience, fills the room with incredible sound, keeps you connected to the people who matter most with FaceTime, and makes it easy to control your smart home,” Apple’s chief marketer Greg Joswiak said in a statement.

Apple said that HomeView will show information from the Messages, Photos, Calendar, and Reminders apps based on who is using the device, powered by Apple Intelligence. It can also be used to make FaceTime calls and as a digital photo frame. It’s equipped with an Apple A18 chip. It supports up to six users.

But while Apple has dabbled in home products and platforms in the past, Tuesday’s announcement shows Apple is making its home products a higher priority under Ternus.

Apple said on Tuesday that its new products, including HomeView, can be used as a smart home hub, coordinating notifications and actions in the home and working with a range of products, including new locks, doorbells, and cameras from LG Electronics and Schneider Electric.

Apple’s integration with the smart home is not just about sales but also helps further lock customers into its own ecosystem. People who use multiple Apple products and connections are less likely to switch to an Android phone.

HomeView can also become a smart home dashboard, Apple said. It can be used to view camera feeds, adjust the thermostat, or lock connected doors around the house.

Apple said that setting up a new smart home device takes one tap from the user’s iPhone.

Tuesday’s launch shows Apple’s confidence as it launches new product categories. But the broader consumer electronics industry has been dealing with price increases and demand deterioration related to component shortages in memory and storage. It also comes as new boss Ternus has reportedly pushed the company to release products faster.

Apple’s new Apple TV 4K got a price hike from $199 to $299, and comes after a similar price increase earlier this year, after Cook said that memory costs for Apple were unsustainable.
