Your iPhone slows down over time. 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 or think you may get one as a gift this holiday season). 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.

With Trump’s Tariffs Linked to Inflation, I’m Tracking 11 Key Products for Price Moves
The deadline for the start of Trump’s heaviest tariffs has been delayed a few weeks, but a new report has nonetheless shown that inflation is once again on the rise.
For the past three months, tariffs have been a hot topic, leaving consumers and businesses alike worried: Will prices increase and by how much? It’s a question more relevant than ever, as President Donald Trump punts another major deadline down the road and a new Consumer Price Index summary showing that inflation was 2.7% in June, the biggest jump since February.
Amid those worries, I’ve been tracking prices every day for 11 key products likely to be hit by tariff-induced price increases, and the answer I’ve come to so far is this: Not so much, at least not yet. The winding road of tariff inflation still stretches before us into an uncertain future, so the threat of price hikes continues to cloud the horizon.
To date, I’ve seen two noteworthy price increases, one for the Xbox Series X and the other for a popular budget-friendly 4K TV. Some other products — including Apple’s popular AirPods — have gone on sale for brief periods.
CNET Tariff Tracker Index
Above, you can check out a chart with the average price of the 11 products included in this piece over the course of 2025. This will help give you a sense of the overall price changes and fluctuations going on. Further down, you’ll be able to check out charts for each individual product being tracked. Based on the numbers so far, the average has gone up noticeably since the start of the year, but this has been driven mostly be a big shifts for a few products, as most price are still stable.
We’ll be updating this article regularly as prices change. It’s all in the name of helping you make sense of things, so be sure to check back every so often. For more, check out CNET’s guide to whether you should wait to make big purchases or buy them now and get expert tips about how to prepare for a recession.
Methodology
We’re checking prices daily and will update the article and the relevant charts right away to reflect any changes. The following charts show a single bullet point for each month, with the most recent one labeled «Now» and showing the current price. For the past months, we’ve gone with what was the most common price for each item in the given month.
In most cases, the price stats used in these graphs were pulled from Amazon using the historical price-tracker tool Keepa. For the iPhones, the prices come from Apple’s official materials and are based on the 128-gigabyte base model of the latest offering of the iPhone 16. For the Xbox Series X, the prices were sourced from Best Buy using the tool PriceTracker. If any of these products happen to be on sale at a given time, we’ll be sure to let you know and explain how those price drops differ from longer-term pricing trends that tariffs can cause.
The 11 products we’re tracking
Mostly what we’re tracking in this article are electronic devices and digital items that CNET covers in depth, like iPhones and affordable 4K TVs — along with a typical bag of coffee, a more humble product that isn’t produced in the US to any significant degree.
The products featured were chosen for a few reasons: Some of them are popular and/or affordable representatives for major consumer tech categories, like smartphones, TVs and game consoles. Others are meant to represent things that consumers might buy more frequently, like printer ink or coffee beans. Some products were chosen over others because they are likely more susceptible to tariffs. Some of these products have been reviewed by CNET or have been featured in some of our best lists.
- iPhone 16, 128GB
- Duracell AA batteries, 24-pack
- Samsung DU7200 65-inch TV
- Xbox Series X
- Apple AirPods Pro 2 with USB-C case
- HP 962 CMY Printer Ink
- Anker 10,000-mAh, 30-watt power bank
- Bose TV speaker
- Oral-B Pro 1000 electric toothbrush
- Lenovo IdeaPad Flex 5i Chromebook, 256GB
- Starbucks 28-ounce ground dark roast coffee
Below, we’ll get into more about each individual product, and stick around till the end for a rundown of some other products worth noting.
iPhone 16
The iPhone is the most popular smartphone brand in the US, so this was a clear priority for price tracking. The iPhone has also emerged as a major focal point for conversations about tariffs, given its popularity and its susceptibility to import taxes because of its overseas production, largely in China. Trump has reportedly been fixated on the idea that the iPhone can and should be manufactured in the US, an idea that experts have dismissed as a fantasy. Estimates have also suggested that a US-made iPhone would cost as much as $3,500.
Something to note about this graph: The price listed is the one you’ll see if you buy your phone through a major carrier. If you, say, buy direct from Apple or Best Buy without a carrier involved, you’ll be charged an extra $30, so in some places, you might see the list price of the standard iPhone 16 listed as $830.
Apple’s been taking a few steps to protect its prices in the face of these tariffs, flying in bulk shipments of product before they took effect and planning to move production for the US market from China to India. A new Reuters report found that a staggering 97% of iPhones imported from the latter country, March through May, were bound for the US. This latter move drew the anger of Trump again, threatening the company with a 25% tariff if they didn’t move production to the US, an idea CEO Tim Cook has repeatedly shot down in the past. This came after Trump gave a tariff exemption to electronic devices including smartphones, so the future of that move seems in doubt now.
Duracell AA batteries
A lot of the tech products in your home might boast a rechargeable energy source but individual batteries are still an everyday essential and I can tell you from experience that as soon as you forget about them, you’ll be needing to restock. The Duracell AAs we’re tracking are some of the bestselling batteries on Amazon.
Samsung DU7200 TV
Alongside smartphones, televisions are some of the most popular tech products out there, even if they’re an infrequent purchase. This particular product is a popular entry-level 4K TV and was CNET’s pick for best overall budget TV for 2025. Unlike a lot of tech products that have key supply lines in China, Samsung is a South Korean company, so it might have some measure of tariff resistance.
After spending most of 2025 hovering around $400, this item has now seen some notable upticks on Amazon, most recently sitting around $450. This could potentially be in reaction to Trump’s announcement of 25% tariffs against South Korea this week.
Xbox Series X
Video game software and hardware are a market segment expected to be hit hard by the Trump tariffs. Microsoft’s Xbox is the first console brand to see price hikes — the company cited «market conditions» along with the rising cost of development. Most notably, this included an increase in the price of the flagship Xbox Series X, up from $500 to $600. Numerous Xbox accessories also were affected and the company also said that «certain» games will eventually see a price hike from $70 to $80.
Initially, we were tracking the price of the much more popular Nintendo Switch as a representative of the gaming market. Nintendo has not yet hiked the price of its handheld-console hybrid and stressed that the $450 price tag of the upcoming Switch 2 has not yet been inflated because of tariffs. Sony, meanwhile, has so far only increased prices on its PlayStation hardware in markets outside the US.
AirPods Pro 2
The latest iteration of Apple’s wildly popular true-wireless earbuds are here to represent the headphone market. Much to the chagrin of the audiophiles out there, a quick look at sales charts on Amazon shows you just how much the brand dominates all headphone sales. While Prime Day might be in the rearview mirror at this point, you can grab a pair of these earbuds for $169, a $30 discount from where they’ve been most of the year.
HP 962 CMY printer ink
This HP printer ink includes cyan, magenta and yellow all in one product and recently saw its price jump from around $72 — where it stayed for most of 2025 — to $80, which is around its highest price over the last five years. We will be keeping tabs to see if this is a long-term change or a brief uptick.
This product replaced Overture PLA Filament for 3D printers in this piece, but we’re still tracking that item.
Anker 10,000-mAh, 30-watt power bank
Anker’s accessories are perennially popular in the tech space and the company has already announced that some of its products will get more expensive as a direct result of tariffs. This specific product has also been featured in some of CNET’s lists of the best portable chargers.
Bose TV speaker
Soundbars have become important purchases, given the often iffy quality of the speakers built into TVs. While not the biggest or the best offering in the space, the Bose TV Speaker is one of the more affordable soundbar options out there, especially hailing from a brand as popular as Bose.
Oral-B Pro 1000 electric toothbrush
They might be a lot more expensive than their traditional counterparts but electric toothbrushes remain a popular choice for consumers because of how well they get the job done. I know my dentist won’t let up on how much I need one. This particular Oral-B offering was CNET’s overall choice for the best electric toothbrush for 2025.
This product hasn’t seen its price budge one way or another most of the year, but while Prime Day might have come and gone, there’s still a $10 coupon listed on Amazon right now, letting you save a little bit of money for the time being.
Lenovo IdeaPad Flex 5i Chromebook
Lenovo is notable among the big laptop manufacturers for being a Chinese company making its products especially susceptible to Trump’s tariffs.
Starbucks Ground Coffee (28-ounce bag)
Coffee is included in this tracker because of its ubiquity —I’m certainly drinking too much of it these days —and because it’s uniquely susceptible to Trump’s tariff agenda. Famously, coffee beans can only be grown within a certain distance from Earth’s equator, a tropical span largely outside the US and known as the «Coffee Belt.»
Hawaii is the only part of the US that can produce coffee beans, with data from USAFacts showing that 11.5 million pounds were harvested there in the 2022-23 season — little more than a drop in the mug, as the US consumed 282 times that amount of coffee during that period. Making matters worse, Hawaiian coffee production has declined in the past few years.
All that to say: Americans get almost all of their coffee from overseas, making it one of the most likely products to see price hikes from tariffs. While this particular bag of beans from Starbucks hasn’t seen its price budge for most of the year, in recent days it ticked up by less than a dollar on Amazon, which could be a sign of further increases to come.
Other products
As mentioned, we occasionally swap out products with different ones that undergo notable price shifts. Here are some things no longer featured above, but that we’re still keeping an eye on:
- Nintendo Switch: The baseline handheld-console hybrid has held steady around $299 most places — including Amazon — since it released in 2017. Whether that price will be affected by tariffs or the release of the Switch 2 remains to be seen. This product was replaced above with the Xbox Series X.
- Overture PLA 3D printer filament: This is a popular choice on Amazon for the material needed to run 3D printers. It has held steady around $15 on Amazon all year. This product was replaced above by the HP 962 printer ink.
Here are some products we also wanted to single out that haven’t been featured with a graph yet:
- Razer Blade 18 (2025), 5070 Ti edition: The latest revision of Razer’s largest gaming laptop saw a $300 price bump recently, with the base model featured an RTX 5070 Ti graphics card now priced at $3,500 ahead of launch, compared to the $3,200 price announced in February. While Razer has stayed mum about the reasoning, it did previously suspend direct sales to the US as Trump’s tariff plans were ramping up in April.
- Asus ROG Ally X: The premium version of Asus’s Steam Deck competitor handheld gaming PC recently saw a price hike from $799 to $899, coinciding with the announcement of the company’s upcoming Xbox-branded Ally handhelds.

Over Half of Teens Regularly Use AI Companions. Here’s Why That’s Not Ideal
The study by Common Sense Media also found that nearly a third of teens are as satisfied, if not more, by conversing with AI rather than humans.

Is your teen using a chatbot for companionship? If you don’t know, you might want to ask. Common Sense Media released a study on Wednesday, in which it found that more than half of pre-adult teenagers regularly use AI companions. Nearly one third of the teens reported that conversations with AI were as satisfying, if not more, than conversations with actual humans.
Researchers also found that 33% of teens use AI companions such as Character.AI, Nomi and Replika «for social interaction and relationships, including conversation practice, emotional support, role-playing, friendship, or romantic interactions.» The study distinguished between anthropomorphic AI bots and more assistance-oriented AI tools such as ChatGPT, Microsoft Copilot or Google’s Gemini.
Considering the growing widespread use of AI companions in teens, the Common Sense Media researchers concluded that their findings supported limiting the use of AI among young people. «Our earlier recommendation stands: Given the current state of AI platforms, no one younger than 18 should use AI companions,» they said, after surveying 1,060 teens aged 13-17 from across the US over the past year.
For the past few years, generative AI has evolved at lightning speed, with new tools regularly available across the world, disrupting business models, social practices and cultural norms. This, combined with an epidemic of social isolation exacerbated by the COVID pandemic, puts teens at risk with technology that their young brains might not be able to handle adequately.
The American Psychological Association warned earlier this year that «we have already seen instances where adolescents developed unhealthy and even dangerous ‘relationships’ with chatbots.» The APA issued several recommendations, including teaching AI literacy to kids and AI developers creating systems that regularly remind teen users that AI companions are not actual humans.
Amid the growing use of chatbots by people to discuss personal problems and get advice, it’s important to remember that while they might seem confident and reassuring, they’re not mental health professionals.

Donkey Kong Bananza Review: The Best Switch Game in Years Is a Switch 2 Exclusive
DK is helping me punch my way through summer.

Summers are about big, fun, mind-numbing movies. Great escapes in the best of ways. I need that right now, and maybe you do too. I’m happy to say that Donkey Kong Bananza is here to whisk you off to multilevel worlds of satisfyingly smashing madness, to cheer you up and give you an excuse to punch the heck out of things. It’s a game my 12-year-old son has loved playing along with me, although I’ve had to find ways to wrestle the game back to play for myself.
I was wowed by Bananza during an early preview a few weeks ago, but after a few weeks of play at home, it’s even better. This is my favorite Switch game since… I have no idea when. Maybe since Super Mario Odyssey.
The catch is that you need the new Nintendo Switch 2 console to play it. Donkey Kong Bananza won’t work on the original Switch — or on any other gaming device. Of course, that’s the whole idea.
Nintendo needed home run games for its new Switch 2 console, and it hit a grand slam with the new Donkey Kong. I still haven’t finished the game, but I already know it’s the best reason to buy a Switch 2 yet.
Donkey Kong Bananza comes out tomorrow, July 17. It’s available for preorder now for $70 from Nintendo.com and other retailers. We’re also keeping track of Nintendo Switch 2 restocks if you’re still seeking a console.
Smashing story with co-op options
In a lot of ways, Bananza feels like Zelda and Mario met in the middle.
The story’s weird, but what Mario (or Nintendo) game isn’t? Donkey Kong’s world has been threatened by a sinister bunch of apes, after a large meteor knocks a mining company deep into the planet’s core. The adventure involves diving down into those sublevels — it’s Donkey Kong Hollow Earth, or Journey to the Center of the Kongiverse. The big difference in this game is that you can destroy just about anything, burrowing and tunneling throughout the game’s large 3D maps.
Technically, this isn’t a true collaborative co-op game, but there’s a mode where Pauline — a young girl who mysteriously fell from the sky and becomes Donkey Kong’s friend — can throw her voice, literally, at things to destroy them. A second player takes over as Pauline and aims and shoots words at enemies, and can absorb material powers from nearby rocks and objects. It’s more engaging than the hat-throwing co-op in Odyssey.
You can Game Share Bananza with a local Switch 2 or Switch 1 in co-op mode to play on two screens, or just play on one. For this review, I wasn’t allowed to Game Share to a second Switch.
The Mario mojo
Bananza is made by the Super Mario Odyssey team, and its 3D platforming feels like a Mario sequel. You can wander through large but still self-contained sublevels that remind me of the Kingdoms in Super Mario Odyssey. As you descend to new levels, the characters you meet and the level’s game mechanics shift up a bit. The levels aren’t as drastically different or quite as weirdly whimsical as the ones in Odyssey, but they feel a lot busier.
Jumping and punching are the main ways to control things, but there are plenty of other moves. There’s also a skill tree of abilities to unlock and power up, which uses points you accumulate by collecting giant, crystal bananas (just go with it). Donkey Kong can also buy new outfits, much like Mario Odyssey, but these outfits (or pieces of outfits) give extra perks, like cold resistance or faster energy recovery.
Each of the levels has goals and sub-bosses to fight, but also secret subchallenges to discover — some of them 3D, some 2D side-scrolling. There are other things to find, in every direction, on any potential hillside or surface, if you just pummel your fists and dig. The free-digging usually involves either finding more crystal bananas or various-sized fossils, which can be collected and redeemed for costumes. There’s gold to accumulate, too, which acts as general currency. But even as I rush to the next goal on any level, I’m equally tempted to just start digging around and see what’s going on somewhere else.
The Zelda zeitgeist
Here’s where Bananza really starts to feel like a lower-key Zelda game, especially when it comes to finding characters and following sub-missions. You can talk to lots of the strange characters in each sublevel, and some share important news. You’ll get directed to a particular goal, and on a 3D map, you can track your progress or warp to other spots. But as the game’s progress starts to wind up and down through sublevels, it begins to feel a lot more quest-y than any Mario game.
Zelda: Tears of the Kingdom kept coming to mind for me. That game’s vast overworld and underworld — and its various ways of finding passages between — is very much like Bananza. Also, like recent Zelda games, you can climb just about anywhere (or surf chunks of rock you rip out of the ground). The outfit perks feel Zelda-like, and so does the game’s sense of real-time, chaotic physics. Some puzzles involve understanding the environment and manipulating it, much like I did many times in Tears.
There’s also a sense of persistence in Bananza. You can create little home bases that let you rest up and change outfits. You’ll meander off and come back to locations. Mario Odyssey had some of this too, but Bananza feels more lived in.
Unlike recent Zeldas, though, this game’s challenges are relatively contained. You won’t have long lists of subquests or stories to lose track of. After spending months away from Zelda, and coming back not remembering what I was meant to do next, I appreciate Bananza’s simpler vibe.
A whole new yet familiar feel
Most importantly, Bananza just feels fresh. I get a little tired, sometimes, of diving back into new Zeldas and Marios that layer legends on top of legends. Donkey Kong’s universe is different from previous Kong games, especially the giant, wrinkled Elders who preside over subworlds like spirits, granting extra transformation powers. This is where the «Bananza» name comes in.
Accumulating enough gold triggers a chance to become a spirit animal. There’s a Bananza version of Kong that has stronger punches, an ostrich that can fly and drop egg bombs, and a zebra that can run fast over ice and water. (I haven’t unlocked any others yet.)
After a week-plus of playing, I’m still consistently surprised by what I’m encountering. But I’m also finding it familiar and comfortable, just like a big summer movie. And that’s what this is: Nintendo’s big blockbuster summer game, one of the best I can remember. Something I don’t want to end, and I’m glad to have more to explore.
I’m also surprised by other things: there’s no online mode, which I don’t mind but feels surprising after Super Mario Wonder’s clever additions. The game download size is only 8GB, shockingly small compared to Switch 2 launch games like Cyberpunk 2077, which were nearly 60GB. I was getting worried about how much storage space I’d have on the Switch 2 over time, but if more games are like Bananza, things will be OK.
My youngest son was instantly interested in Bananza, so much so that he didn’t want me playing without him. I had to, though, so I could carve enough time out to play. We’re going to backtrack and play again, and he’ll start playing, too. Will Bananza feel as replayable and infinitely fun as many of Nintendo’s best? I can’t entirely tell yet, but there’s already so much I’ve skipped over in so many levels, I don’t doubt it. There’s also a 3D art mode thrown in as a bonus where you use the Joy-Cons to sculpt and paint ape heads and bunches of bananas.
Donkey Kong makes it worth buying a Switch 2
Bananza is a great sign for where Nintendo’s heading with the Switch 2. It feels like a more evolved version of many Switch games of the past, but just like Mario Kart World, the other major Switch 2 exclusive, it takes the good ideas even further. Bananza is also an extension of Nintendo’s universe, including the Super Mario Movie, which has a Donkey Kong that looks like this one, and Super Nintendo World, which has a Donkey Kong land, too. And yes, Super Nintendo World’s Donkey Kong Power-Up bands even work like Amiibo with this game.
This is a game as vibrant and kinetic as Sony’s fantastic Astro Bot and similarly full of things to search for and do. In comparison, Super Mario Odyssey now seems surprisingly quiet and chill.
And yes, this game is worth getting a Switch 2 for — that was the idea all along. It’s nice to see that Nintendo really pulled it off, though. Combined with Mario Kart World, this is a heck of a one-two punch. I’d still love a proper 3D Mario sequel someday, but Bananza is practically that right now.
