Keep Your Phone From Overheating When the Temperature Spikes
Hot weather can damage your iPhone or Android phone, sometimes permanently. Learn how to keep it safe.
As the East Coast of the US faces high winds and flooding from Hurricane Erin, the West Coast is about to be hit with a brutal heat wave. Along with increased danger from wildfires, the hot temperatures also create risks for your personal tech, specifically your smartphone.
Phones are more sensitive to extreme temperatures than most people realize. While the Pixel 6A made news earlier this year because of exploding, even the latest iPhone and Android models can overheat quickly if left in the sun or used heavily during hot weather.
When your phone gets too hot, it can slow down, shut off or even suffer long-term damage. High temperatures put stress on the battery and internal components, which can lead to reduced performance and a shorter lifespan. Whether you’re out on a hike, watching videos by the pool, or just leaving your phone on the dashboard, here’s what you need to know about overheating — and how to keep your device safe this summer.
Why is your phone overheating in the first place?
High temperatures — over 95 degrees Fahrenheit, according to Apple — can cause your phone to take precautions to protect its components. Your phone might overheat for many reasons, but here are some of the most common culprits:
- Leaving your phone in direct sunlight
- Keeping your phone in a hot environment, like a car on a hot day
- Using your phone’s navigation system or other system-intensive tasks in hot conditions
- Overusing your phone when it’s charging
- A faulty battery or charger
- Bugs in the software
- Rogue apps or malware
Your phone might overheat from other causes, like a malfunctioning application or even a suffocating phone case, but the reasons above are the most likely causes of your phone getting too hot.
What does overheating do to your phone?
If the interior temperature of your phone exceeds its normal operating range and the device overheats, you can expect issues:
- You may not be able to use your phone
- Operations on your phone may slow down
- Charging may slow or completely stop
- Your signal may be weakened
- Your camera’s flash may be disabled
There are also possible permanent harmful effects: Overheating can cause lasting damage to the battery, SIM card and other crucial parts inside your phone.
So how can you prevent your phone from overheating?
The most important thing is to keep your phone out of direct sunlight when possible, especially when it’s warm. Your phone might be fine in the grass on an overcast day, but the warmer the temperature, the less your phone can withstand the sun. At the beach, your phone can overheat in just a few minutes in the sun. The same is true if you put it in a sunny spot on the dash or seat of your car.
Instead, get your phone out of the direct light, whether it’s in your pocket, inside a backpack or under a towel/blanket or dashboard. Anyplace that will keep it away from sunlight will work.
It’s fairly easy to protect your phone from the sun, but high temperatures alone can also cause your phone to overheat. After only an hour, the inside of a car can reach 143 degrees Fahrenheit when it’s 100 degrees outside, for example, so a phone left in your cup holder could quickly overheat and get damaged. The short answer: Don’t keep your phone in a hot environment for an extended period of time, even if it’s not in direct sunlight. That includes your car, a sauna, the kitchen, the middle of the desert or anywhere near a fire.
Your phone’s optimal internal temperature should be somewhere between 32 degrees and 95 degrees Fahrenheit (0 degrees and 35 degrees Celsius). To prevent overheating, Apple recommends keeping the device in a place where the temperature is between negative 4 degrees and 113 degrees Fahrenheit (negative 20 degrees and 45 degrees Celsius).
While it might be tempting, don’t stick your phone in the freezer to cool it down. The Apple community boards have lots of warnings about the damage you can do to your phone by putting it in an icebox.
You should also follow these tips to prevent your phone from overheating
- Don’t use graphics- or processor-intensive apps when your phone is charging. That includes massive mobile video games like PUBG Mobile or streaming apps like Netflix and Hulu.
- Update your phone system software and apps to the latest software available. A bug in the software can cause overheating issues, so always stay up-to-date with your software.
- Steer clear of third-party chargers. You’ll be fine almost always, but a cheaply designed charger could cause your phone to overheat.

Google races to put Gemini at the center of Android before Apple’s AI reboot
Google is using its latest Android rollout to position Gemini as the AI layer across phones, Chrome, laptops and cars.
Google is using its latest Android rollout to make Gemini less of a chatbot and more of an operating layer across the phone, browser, car and laptop, just weeks before Apple is expected to show its own Gemini-powered Apple Intelligence reboot at WWDC.
Ahead of its Google I/O developer conference next week, the company previewed a number of Android updates, including AI-powered app automation, a smarter version of Chrome on Android, new tools for creators, a redesigned Android Auto experience, and a sweeping set of new security features.
Alphabet is counting on Gemini to help Google compete directly with OpenAI and Anthropic in the market for artificial intelligence models and services, while also serving as the AI backbone across its expansive portfolio of products, including Android. Meanwhile, Gemini is powering part of Apple’s new AI strategy, giving Google a role in the iPhone maker’s reset even as it races to prove its own version of personal AI on the phone is further along.
Sameer Samat, who oversees Google’s Android ecosystem, told CNBC that Google is rebuilding parts of Android around Gemini Intelligence to help users complete everyday tasks more easily.
“We’re transitioning from an operating system to an intelligence system,” he said.
As part of Tuesday’s announcements. Google said Gemini Intelligence will be able to move across apps, understand what’s on the screen and complete tasks that would normally require a user to jump between multiple services. That means Android is moving beyond the traditional assistant model, where users ask a question and get an answer, and acting more like an agent.
For instance, Google says Gemini can pull relevant information from Gmail, build shopping carts and book reservations. Samat gave the example of asking Gemini to look at the guest list for a barbecue, build a menu, add ingredients to an Instacart list and return for approval before checkout.
A big concern surrounding agentic AI involves software taking action on a user’s behalf without permissions. Samat said Gemini will come back to the user before completing a transaction, adding, “the human is always in the loop.”
Four months after announcing its Gemini deal with Google, Apple is under pressure to show a more capable version of Apple Intelligence, which has been a relative laggard on the market. Apple has long framed privacy, hardware integration and control of the user experience as its advantages.
Google’s Android push is designed to show it can bring AI deeper into the device experience while still giving users control over what Gemini can see, where it can act and when it needs confirmation.
The app automation features will roll out in waves, starting with the latest Samsung Galaxy and Google Pixel phones this summer, before expanding across more Android devices, including watches, cars, glasses and laptops later this year.
The company is also redesigning Android Auto around Gemini, turning the car into another major surface for its assistant. Android Auto is in more than 250 million cars, and Google says the new release includes its biggest maps update in a decade and Gemini-powered help with tasks like ordering dinner while driving.
Alphabet’s AI strategy has been embraced by Wall Street, which has pushed the company’s stock price up more than 140% in the past year, compared to Apple’s roughly 40% gain. Investors now want to see how Gemini can become more central to the products people use every day.

Waymo recalls 3,800 robotaxis after glitch allowed some vehicles to ‘drive into standing water’
Waymo issued a voluntary recall of about 3,800 of its robotaxis to fix software issues that could allow them to drive into flooded roadways.
Waymo is recalling about 3,800 robotaxis in the U.S. to fix software issues that could allow them to “drive onto a flooded roadway,” according to a letter on the National Highway Traffic Safety Administration’s website.
The voluntary recall is for Waymo vehicles that use the company’s fifth and sixth generation automated driving systems (or ADS), the U.S. auto safety regulator said in the letter posted Tuesday.
Waymo autonomous vehicles in Austin, Texas, were seen on camera driving onto a flooded street and stalling, requiring other drivers to navigate around them. It’s the latest example of a safety-related issue for the Alphabet-owned AV unit that’s rapidly bolstering its fleet of vehicles and entering new U.S. markets.
Waymo has drawn criticism for its vehicles failing to yield to school buses in Austin, and for the performance of its vehicles during widespread power outages in San Francisco in December, when robotaxis halted in traffic, causing gridlock.
The company said in a statement on Tuesday that it’s “identified an area of improvement regarding untraversable flooded lanes specific to higher-speed roadways,” and opted to file a “voluntary software recall” with the NHTSA.
“Waymo provides over half a million trips every week in some of the most challenging driving environments across the U.S., and safety is our primary priority,” the company said.
Waymo added that it’s working on “additional software safeguards” and has put “mitigations” in place, limiting where its robotaxis operate during extreme weather, so that they avoid “areas where flash flooding might occur” in periods of intense rain.

Qualcomm tumbles 13% as semiconductor stocks retreat from historic AI-fueled surge
Semiconductor equities reversed sharply after a broad AI-driven advance, with Qualcomm suffering its worst day since 2020 amid inflation concerns and rising oil prices.
Semiconductor stocks fell sharply on Tuesday, reversing course after an extensive rally that had expanded the artificial intelligence investment theme well past Nvidia and driven the industry to unprecedented levels.
Qualcomm plunged 13% and was on track for its steepest single-day decline since 2020. Intel shed 8%, while On Semiconductor and Skyworks Solutions each lost more than 6%. The iShares Semiconductor ETF, which benchmarks the overall sector, fell 5%.
The sell-off came after a key gauge of consumer prices came in above forecasts, and as conflict in Iran pushed crude oil higher—prompting investors to shift away from riskier assets.
The preceding advance had widened the AI opportunity set beyond longtime industry leader Nvidia, which for much of the past several years had largely carried the market to new peaks on its own.
Explosive appetite for central processing units, along with the graphics processing units that power large language models, has sent chipmakers to all-time highs.
Market participants are wagering that the shift from AI model training to autonomous agents will lift demand for additional AI hardware. Among the beneficiaries are memory chip producers, which are raising prices as supply remains tight.
Micron Technology slid 6%, and Sandisk cratered 8%. Sandisk’s stock has surged more than six times over since January.
