Summer 2025 Survival Guide: Tips to Keep Your Phone Cool During This Heat Wave

As temperatures soar past record highs, here’s how to prevent your iPhone or Android from overheating.

With a blistering heat dome bringing triple-digit temperatures to millions of Americans this week, staying cool is the top priority — but your phone needs protection, too. Phones are more sensitive to extreme temperatures than most people realize. Even the latest models, like the Pixel 9 Pro or iPhone 16, 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.

Whether it’s your iPhone or Android device, you can’t stop all instances of overheating, but there are many things you can do. Here’s what you need to know.

Why is your phone overheating in the first place?

High temperatures — over 95 degrees, 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 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 from 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. Same 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 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 32º and 95º F (0º and 35º C). To prevent overheating, Apple recommends keeping the device in a place where the temperature is between -4º and 113º F (-20º and 45º C).

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.

New Bill Aims to Block Both Online Adult Content and VPNs: How Your VPN Could Be Affected

A proposed bill in Michigan has a broad reach that covers everything from adult AI content to manga and even depictions of transgender people. It includes a VPN ban to avoid workarounds.

If you live in Michigan, you might not be able to legally use a VPN soon if a new bill is passed into law. On Sept. 11, Michigan Republican representatives proposed far-reaching legislation banning adult internet content.

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.

VPNs, or virtual private networks, are software suites often used as workarounds to avoid similar content bans that have passed in states like Texas, Louisiana, Mississippi and the UK. VPNs can be purchased with subscriptions or downloaded and are also built into some browsers and Wi-Fi routers.

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 for 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,» Perrino said.

The Anticorruption of Public Morals Act has not passed the Michigan House of Representatives committee or been voted on by the Michigan Senate, and it’s not clear how much support the bill 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?

Could VPNs still get around this type of ban? That’s a complex question that this bill doesn’t really address.

«From a technical standpoint, ISPs can attempt to distinguish VPN traffic using deep packet inspection, or they can block known VPN IP addresses,» said NordVPN privacy advocate Laura Tyrylyte. «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.

«Some VPNs offer obfuscation — which tries to disguise VPN traffic as standard web traffic — using dedicated servers or custom VPN protocols, like NordVPN’s NordWhisper or Proton VPN’s Stealth,» said CNET senior editor Moe Long. «But note that obfuscation isn’t foolproof.»

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. VPNs can even use server tricks, such as RAM-only servers that automatically reboot to erase data after every browsing session.

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 recommend the right VPNs for the job, from speedy browsing to privacy while traveling.
