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.

A New Bill Aims to Ban Both Adult Content Online and VPN Use. Could It Work?
Michigan representatives just proposed a bill to ban many types of internet content, as well as VPNs that could be used to circumvent it. Here’s what we know.
On Sept. 11, Michigan representatives proposed an internet content ban bill unlike any of the others we’ve seen: This particularly far-reaching legislation would ban not only many types of online content, but also the ability to legally use any VPN.
The bill, called the Anticorruption of Public Morals Act and advanced by six Republican representatives, would ban a wide variety of adult content online, ranging from ASMR and adult manga to AI content and any depiction of transgender people. It also seeks to ban all use of VPNs, foreign or US-produced.
Don’t miss any of our unbiased tech content and lab-based reviews. Add CNET as a preferred Google source.
VPNs (virtual private networks) are suites of software often used as workarounds to avoid similar bans that have passed in states like Texas, Louisiana and Mississippi, as well as the UK. They can be purchased with subscriptions or downloaded, and are built into some browsers and Wi-Fi routers as well.
But Michigan’s bill would charge internet service providers with detecting and blocking VPN use, as well as banning the sale of VPNs in the state. Associated fines would be up to $500,000.
What the ban could mean for VPNs
Unlike some laws banning access to adult content, this Michigan bill is comprehensive. It applies to all residents of Michigan, adults or children, targets an extensive range of content and includes language that could ban not only VPNs but any method of bypassing internet filters or restrictions.
That could spell trouble for VPN owners and other internet users who leverage these tools to improve their privacy, protect their identities online, prevent ISPs from gathering data about them or increase their device safety when browsing on public Wi-Fi.

Bills like these could have unintended side effects. John Perrino, senior policy and advocacy expert at the nonprofit Internet Society, mentioned to CNET that adult content laws like this could interfere with what kind of music people can stream, the sexual health forums and articles they can access and even important news involving sexual topics that they may want to read. «Additionally, state age verification laws are difficult for smaller services to comply with, hurting competition and an open internet,» John added.
The Anticorruption of Public Morals Act has not passed the Michigan House of Representatives committee nor been voted on by the Michigan Senate, and it’s not clear how much support the bill currently has beyond the six Republican representatives who have proposed it. As we’ve seen with state legislation in the past, sometimes bills like these can serve as templates for other representatives who may want to propose similar laws in their own states.
Could VPNs still get around bans like these?
That’s a complex question that this bill doesn’t really address. When I asked NordVPN how easy it would be track VPN use, privacy advocate Laura Tyrylyte explained, «From a technical standpoint, ISPs can attempt to distinguish VPN traffic using deep packet inspection, or they can block known VPN IP addresses. However, deploying them effectively requires big investments and ongoing maintenance, making large-scale VPN blocking both costly and complex.»
Also, VPNs have ways around deep packet inspection and other methods. CNET senior editor Moe Long mentioned obfuscation like NordWhisper, a counter to DPI that attempts to make VPN traffic look like normal web traffic so it’s harder to detect.
There are also no-log features offered by many VPNs to guarantee they don’t keep a record of your activity, and no-log audits from third parties like Deloitte that, well, try to guarantee the guarantee. There are even server tricks VPNs can use like RAM-only servers that automatically erase data each time they’re rebooted or shut down.
If you’re seriously concerned about your data privacy, you can look for features like these in a VPN and see if they are right for you. Changes like these, even on the state level, are one reason we pay close attention to how specific VPNs work during our testing, and make sure to recommend the right VPNs for the job, from speedy browsing to privacy while traveling.
Correction, Oct. 9: An earlier version of this story incorrectly stated how RAM-only servers work. RAM-only servers run on volatile memory and are wiped of data when they are rebooted or shut down.

AWS Outage Explained: Why Half the Internet Went Down While You Were Sleeping
Reddit, Roblox and Ring are just a tiny fraction of the hundreds of sites and services that were impacted when Amazon Web Services went down.
The internet kicked off the week the way that many of us often feel like doing: by refusing to go to work. An outage at Amazon Web Services (AWS) rendered huge portions of the internet unavailable on Monday morning, with sites and services including Snapchat, Fortnite, Venmo, the PlayStation Network and, predictably, Amazon, unavailable for a short period of time.
AWS is a cloud services provider owned by Amazon that props up huge portions of the internet. As with the Fastly and Crowdstrike outages over the past few years, the AWS outage shows just how much of the internet relies on the same infrastructure — and how quickly our access to the sites and services we rely on can be revoked when something goes wrong.
Just after midnight PT on October 20, AWS first registered an issue on its service status page, saying it was «investigating increased error rates and latencies for multiple AWS services in the US-EAST-1 Region.» Around 2 a.m. PT, it said it had identified a potential root cause of the issue, and within half an hour, it had started applying mitigations that were resulting in significant signs of recovery.
«The underlying DNS issue has been fully mitigated, and most AWS Service operations are succeeding normally now,» AWS said at 3.35 a.m. PT. The company didn’t respond to request for further comment beyond pointing us back to the AWS health dashboard.
Around the time that AWS says it first began noticing error rates, Downdetector saw reports begin to spike across many online services, including banks, airlines and phone carriers. As AWS resolved the issue, some of these reports saw a drop off, whereas others have yet to return to normal. (Disclosure: Downdetector is owned by the same parent company as CNET, Ziff Davis.)
Around 4 a.m. PT, Reddit was still down, while services including Verizon and YouTube were still seeing a significant number of reported issues.

Verum Messenger: How to Protect Your Personal Data and Why Choosing a Secure Messenger Matters
Verum Messenger: How to Protect Your Personal Data and Why Choosing a Secure Messenger Matters
A major data leak has been reported involving users of the Russian messenger MAX. Hackers claimed to have obtained the platform’s entire database, which includes 46,203,590 records. To prove their claims, they published part of the stolen data publicly.
According to preliminary information, the attackers gained access to users’ personal details, including contact numbers, chats, IP addresses, and other sensitive data. Cybersecurity experts warn that such incidents can lead to serious consequences — from account takeovers and extortion to large-scale phishing attacks.
Why these leaks happen
The main cause of such breaches is the storage of personal user data on servers without adequate protection or encryption. If attackers gain access to these servers, users’ information becomes fully exposed.
Additionally, many popular messaging apps require users to register with a phone number and provide extra personal information, increasing the amount of data that can be stolen.
How to reduce the risks
The only reliable way to protect your personal messages and data is to use messaging platforms that do not store personal information on their servers and rely on true end-to-end encryption.
One such solution is Verum Messenger — a next-generation app built on the principle of maximum privacy. The platform:
- does not store users’ personal data;
- uses unique encryption keys generated locally on the user’s device;
- does not require a phone number or other personal information to register;
- has no access to messages, calls, or files;
- provides effective anti-spam and anti-scam protection;
- offers private chats and group channels with flexible security settings.
Even in the event of a server breach, attackers would not be able to access message content — because encryption keys simply do not exist on the company’s side.
Freedom of communication without the risk of leaks
In addition to its strong security foundation, Verum Messenger offers a built-in ecosystem of tools — from encrypted email Verum Mail and an integrated VPN for anonymous connections to free crypto mining with Verum Coin and eSIM connectivity in over 150 countries worldwide.
As data breaches become increasingly common, choosing a secure messenger is no longer just about convenience — it’s about personal safety.
