Summer heat could damage your smartphone. Here's how to protect it
Both the iPhone and Samsung's Galaxy line of smartphones are built to operate from 32 degrees to 95 degrees Fahrenheit, reporting from the USA TODAY Network shows. Apple notes using your iPhone in very hot conditions "can permanently shorten battery life."
Apps and games can also clunk up processing capabilities of your phone, causing it to heat up.
Apple also warns users to start their device within a specific temperature range: minus 4 degrees to 113 degrees Fahrenheit. Don't leave your device in your car, the company warns, because temperatures in parked cars can exceed this range.
The new Samsung Galaxy Z Fold7 devices: Thinner, lighter and packed with power
Here's what to know about keeping your phone cool this summer:
What causes your phone to warm up?
Leaving your device in a car on a hot day, leaving in direct sunlight for an extended period of time and using certain features in hot conditions or direct sunlight for an extended period of time are all factors that contribute to a hot phone.
Charging your device can cause it to heat up a bit, too, whether wirelessly or via a cord.
How do I know whether my smartphone is heating up?
Your iPhone or Galaxy phone will give away signals that it's starting to reach a point where they're getting too hot.
Samsung notes that "access to certain features/functions may temporarily freeze as a means to protect the device" when it crosses heat thresholds.
On the iPhone, Apple said the device will make several adjustments, including slower charging, dimmer displays, and the flashlight and flash for photos are disabled.
Once your phone gets too hot, it will display warnings that the device needs to cool down before you can use it again. Both iPhone and Galaxy models will still allow you to make emergency calls during that time.
"If the device overheats or reaches a certain temperature, a warning message will appear to prevent device failure, skin irritations and damages, and battery leakage," Samsung says. "To lower the device's temperature, the screen brightness and the performance speed will be limited and battery charging will stop. Running apps will be closed and all calling and other features will be limited, except for emergency calls, until the device cools down.
"If a second message appears due to a further increase of the device's temperature, the device will turn off. Do not use the device until the device's temperature drops below the specified level," the company adds.
What should I do if my phone gets too hot?
If your device gets too hot, turn it off, move it to a cooler environment (away from direct sunlight), and allow it to cool down, according to Apple.
"iOS and iPadOS devices have built-in protections to prevent overheating. If the interior temperature of your device exceeds the normal operating range, your device will protect its internal components by attempting to regulate its temperature," Apple says.
My phone shut down from the heat — now what?
Don't panic. Most modern devices have safeguards, and automatic shutdowns are part of the plan. Take your smartphone out of your pocket and put it somewhere out of the sun as soon as possible.

TSMC quarterly profit seen hitting record but Trump tariffs, forex a concern
TAIPEI (Reuters) -TSMC, the world's main producer of advanced AI chips, is expected to post a 52% jump in second-quarter profit to record levels on Thursday, though U.S. tariffs and a strong Taiwan dollar could weigh on its outlook. Taiwan Semiconductor Manufacturing Co, the world's largest contract chipmaker and a key supplier to Nvidia and Apple, is forecast to report net profit of T$377.4 billion ($12.9 billion) for the three months through June 30, according to an LSEG SmartEstimate compiled from 21 analysts. SmartEstimates place greater weight on forecasts from analysts who are more consistently accurate. The company will report the headline profit figure at 0530 GMT which will be followed by an earnings call from 0600 GMT that will include third-quarter guidance. TSMC has already flagged a rise in second-quarter revenue of 38.6%. Any profit result above T$374.68 billion would mark the company's highest-ever quarterly net income and its sixth consecutive quarter of profit growth. It remains unclear just how much U.S. President Donald Trump's tariffs will affect TSMC. Taiwan was threatened with a 32% reciprocal tariff rate in April but has yet to be notified of an updated figure that some countries have received. Trump also said this month that tariffs on semiconductors are likely to come soon. The company said in June that U.S. tariffs were having some indirect impact, noting they can lead to slightly higher prices, which may in turn weigh on demand. In March, TSMC announced a $100 billion investment in the U.S. alongside Trump at the White House, on top of $65 billion pledged for three Arizona plants - two of which have been built. Another key issue is the Taiwan dollar's 12% appreciation against the greenback so far this year. TSMC has said a 1% appreciation in the Taiwan dollar typically reduces its gross margin by 0.4 percentage points. In June, the company said that strengthening in the Taiwan dollar had shaved more than 3 percentage points off its gross margin. Shares in TSMC surged some 80% last year but have climbed just 5% for the year to date on worries about tariffs and unfavourable currency exchange rates.

I Finally Held a Foldable That Doesn't Feel Like Two Stacked Phones: the Galaxy Z Fold 7
If I closed my eyes and you put the Samsung Galaxy Z Fold 7 in my hands, I would think you'd handed me one of dozens of ordinary phones that share a similar shape and weight. But when I'd open my eyes, and then unfold the two panels of this new phone, well, that's a whole different story. I got to check out the Z Fold 7 with eyes wide open during Samsung's Unpacked event in New York last week, along with the Z Flip 7 and Z Flip 7 FE. I've used many foldable phones, but the feel of these struck me as being the future of the category. Now Playing: Ultra Thin: First Look at the Galaxy Z Fold 7 and Z Flip 7 02:45 At 8.9mm thick when folded and weighing 215 grams, the Galaxy Z Fold 7 doesn't feel much different than a standard slate phone. The 6.5-inch cover display makes it something I can see myself willingly using to scroll through social media, text and watch videos. But when opened, Samsung's book-style foldable is anything but ordinary. At just 4.2mm thick, it boasts a wildly slim profile that steals the spotlight from even the 5.8mm-thick Galaxy S25 Edge. The 8-inch inner display is 11% larger than the one on last year's Z Fold 6, which should help with multitasking. And a Gorilla Glass Ceramic 2 cover and Victus 2 back make it feel nice and sturdy. The Z Fold 7 feels exactly like what foldable phones have strived to be all along: thin, lightweight and spacious -- and also as "normal" as possible, at least where it matters. It also features an impressive 200-megapixel main camera, just like the not-so-thin S25 Ultra. The Galaxy Z Fold 7 weighs 215 grams, and has a more spacious display. Joseph Maldonado/CNET/PCMag In an exclusive interview, Drew Blackard, Samsung's senior vice president of mobile product management, told CNET that by slimming down the Fold and leveling up the cameras, the book-style phone "is now a mainstream form factor." After holding the phone, I can understand what he means. The Z Fold 7 does away with the thicker build and scaled-back cameras that previously characterized foldables, and introduces something that feels equal parts sleek and familiar. Samsung is by no means the first company to launch a thin foldable; Oppo's Find N5, Huawei's Mate X6 and Honor's Magic V3 also boast impressively slim designs, to name a few. But with the release of both the Galaxy S25 Edge and now the Galaxy Z Fold 7, Samsung is doubling down on the skinny phone craze. The Galaxy Z Fold 7 boasts the same 200-megapixel wide camera as the S25 Ultra. Joseph Maldonado/CNET/PCMag An Ultra experience on an ultra-thin phone By bringing its 200-megapixel wide camera to the Z Fold 7 and S25 Edge, Samsung is proving you don't have to compromise camera quality for a slimmer build. It's a notable example of a foldable breaking away from the hardware limitations that have traditionally scaled back the cameras. It'll be interesting to see how competitors strive to match or outdo that feat. The Z Fold 7 also has a 12-megapixel ultrawide and 10-megapixel telephoto camera, as well as 10-megapixel selfie cameras on the inner and cover screens. I look forward to testing the phone's cameras out in the real world. Like the S25 series, the Galaxy Z Fold 7 packs a Snapdragon 8 Elite chip. It comes out of the box with One UI 8 and Android 16. What I'm perhaps most relieved about is that the Z Fold 7's battery maintains last year's 4,400-mAh capacity, despite the new phone's slimmer build. The biggest downside of the S25 Edge is its 3,900-mAh battery, giving it the lowest capacity across the S25 series. I was fully prepared for the Z Fold 7 to take a similar hit, but its expanded real estate helped save it from that pitfall. Battery life is one of the biggest considerations when people buy a new phone, according to a CNET survey, so it's good Samsung didn't scale that back. We'll see how it actually holds up in my day-to-day use and if it's a match for my endless TikTok scrolling and photo taking. Joseph Maldonado/CNET/PCMag Not-so-slim price The Galaxy Z Fold 7's cutting-edge specs don't come cheap. The phone starts at $2,000, which is $100 more than last year's Z Fold 6. You're certainly paying a premium for both that slimmer build (the S25 Edge starts at $1,100) and the Ultra-grade camera (the S25 Ultra starts at $1,300). The Z Fold 7 is available in jet black, blue shadow and silver shadow, as well as an exclusive mint color when you order on Preorders are open now, and the phones arrive July 25.

Hot deal: Samsung Galaxy Buds 3 Pro record-low price keeps dropping!
Ryan Haines / Android Authority The Samsung Galaxy Buds 3 Pro's record-low prices keep going even lower. Today, they're only $109.99! That's a massive discount on Samsung's best earbuds, which usually go for $249.99. Buy the Samsung Galaxy Buds 3 Pro for just $109.99 ($140 off) This offer is available from Woot, an Amazon-owned deals website. They're only available in Silver, and there's a limit of two units per customer. One thing to keep in mind is that this is an international version of the earbuds. This means you don't get a full manufacturer warranty, but Woot throws in its own 90-day warranty. The sale is available for three days or 'until sold out.' Samsung Galaxy Buds 3 Pro Samsung Galaxy Buds 3 Pro Situational awareness, and utility lights Compared to the nearly identical Buds3, the Samsung Galaxy Buds3 Pro offer better sound quality, thanks to 2-way speakers, and enhanced situational awareness, thanks to advanced Ambient sound offerings. Audio is delivered through a 10.5mm DD speaker, and a 6.1mm Planar speaker. Bluetooth 5.4 offers solid connectivity and features such as Siren Detect can automatically switch ANC and Ambient Noise levels on the fly. The new Interpreter mode works with your phone to offer translations. See price at Woot! Save $140.00 This is a really hot deal, guys! The Samsung Galaxy Buds 3 Pro are excellent earbuds, but we had a hard time justifying the $249.99 retail price. At just $109.99, though, they are quite the steal. These earbuds offer excellent sound quality and really good ANC performance. Based on the objective tests from our sister site, they can block out 76% of external noise. Of course, these are premium earbuds, so the rest of the experience has to be just as good as the audio. These offer a pretty nice 4.5-hour battery life. And this is without even counting the juice in the case. They also offer a pretty neat IP57 rating, so you won't have to worry about a bit of sweat, rain, or dust. The design is also pretty nice and unique. Ryan Haines / Android Authority While these will work very well with any device, some features are Samsung-exclusive. These include auto-switching between Samsung products, live translation, and sound detection. The latter will disable ANC if it detects essential noises, such as emergency vehicle sirens. As you can see, while really cool, those features aren't exactly essential to the experience. Non-Samsung phone owners can still take advantage of gesture support, including touch, swipe, and press gestures. You'll also enjoy capabilities like 360-degree audio, Find My support, and more. At just $109.99, it's hard to beat this offer. Go get them before they are gone! We can only assume these will be flying off the shelves. If you're not quite convinced, though, our audio experts at have put together a comprehensive list of the best wireless earbuds. You'll find plenty of great alternatives there!
