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.

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. Almost all of the time you’ll be fine, but a cheaply designed charger could cause your phone to overheat.

Razer’s Wolverine V3 Pro 8K Controller Won’t Replace My Mouse and Keyboard, but Here’s Where It Shines

I applaud the absurdly high polling rate, six extra remappable buttons and TMR sticks, but let me tell you why I’m sticking with my keyboard and mouse for most games I play.

The Razer Wolverine V3 Pro 8K PC controller was not built for me, but admittedly, this has more to do with me as a gamer than the controller itself. I grew up playing the PlayStation 3 and PS4 consoles, cutting my teeth on slim, compact DualSense controllers. Over the past five years, I’ve gamed exclusively on my PC and have grown accustomed to the increased precision of a mouse and keyboard.

The Razer Wolverine V3 Pro 8K PC controller is the antithesis of a DualSense controller. It’s a chunky piece of hardware that might feel natural if you were raised on an Xbox and its bulky controllers, but it took me multiple gaming sessions to get acclimated to the sheer size of the Wolverine V3 and how it fit into my hands, especially since I don’t use a claw grip.

Size aside, this is a PC controller with every bell and whistle you can think of — and its price of $200 reflects that. The 8,000Hz polling rate ensures buttery smooth inputs with no lag, and tunnel magnetoresistance joysticks make every in-game movement feel fluid and calculated. Six extra remappable buttons help you up your game — they’re super handy for hero shooters like Marvel Rivals and hectic games like Battlefield 6. This is a premium product for gamers who are hoarding some serious hardware.

Its price is in line with other premium controllers. One of CNET’s best Xbox controllers is the Wolverine V3 Pro for Xbox, which also costs $200. Similar controllers like the Scuf Instinct Pro and Vitrix Pro BFG are in the same ballpark, pricewise, but the Wolverine V3 Pro 8K PC has a winning combination of competitive variables that make it feel exceptionally easy to use.

This controller is chock full of top-of-the-line technology and feels satisfying to use, but it needs to clear a high bar to feel truly worthwhile as a dedicated PC controller.

Chunky controller, satisfying feedback

When CNET’s Josh Goldman reviewed the Wolverine V3 Pro Xbox wireless controller, he called it «just about perfect.» If it isn’t broken, don’t fix it: Razer replicated many of its successes with the Wolverine V3 Pro PC controller.

The Wolverine V3 Pro 8K PC is the same size as the Wolverine V3 Pro Xbox controller, which is to say it’s a bit chunkier than a standard Xbox wireless controller, but it’s surprisingly much lighter than its Xbox cousin. It weighs just 220 grams, which is appreciably lighter than the Xbox version that weighs 304 grams. And while the Wolverine V3 Pro 8K PC is nowhere near as slim as a DualSense controller, it’s still much lighter than its Sony competitor — a stock DualSense controller weighs 280 grams.

Every button on this controller has a crisp, clean clickiness that scratches the same mental itch that a good mechanical keyboard might. Whether you’re gripping the trigger, pressing a button or squeezing one of the four remappable back paddles, you’ll hear incredibly satisfying auditory feedback that leaves no doubt that the controller is receiving your inputs. At one point, while I sat through a particularly long matchmaking queue, I found myself squeezing the triggers to entertain myself — the snappy pops were enough to keep me off TikTok.

The biggest difference between the V3 Pro Xbox and V3 Pro PC controllers is the variable polling rate — that dictates how often your controller is communicating with the computer. It’s like a refresh rate for your crosshair positioning.

The Wolverine V3 Pro Xbox just can’t compete here: That controller has a wired 1,000Hz polling rate for PC gameplay. The V3 Pro PC controller can be toggled for multiple polling rates, with an 8,000Hz maximum setting. This means the PC controller can report your input data eight times faster than the Xbox controller.

Every movement, turn and button press feels incredibly fluid. It’s safe to say that there’s no input lag with the Wolverine V3 PC controller, but I don’t think it matters too much for moment-to-moment first-person shooter gameplay. If you’re driving a car (or a tank) and you need to stop on a hairpin, you might appreciate Razer’s HyperPolling technology. If you’re not playing a tactical shooter like Counter-Strike or Rainbow Six: Siege, that 8,000Hz polling rate is overkill — if you’re a casual gamer crushing Call of Duty public lobbies with your pals, you’re probably not going to notice it in any of your firefights.

Better than a mouse and keyboard? That’s a little more complicated

I tested out the Wolverine V3 Pro 8K PC controller on Marvel Rivals, ARC Raiders and Battlefield 6 (my current first-person shooter obsession). It’s an extremely solid choice for at least two of these games, and I likely won’t be using my DualSense controller anytime soon.

I had a great time firing magic bolts in Marvel Rivals and rolling tanks through the streets of Cairo in Battlefield 6, but this is a controller that was supposedly designed for high-level shooter gameplay. I’m saddened to report that, when it comes to dominating a first-person shooter match or competing to survive in an extraction shooter, I’d much rather stick to a mouse and keyboard.

In close-range battles, I didn’t feel like the Wolverine controller particularly helped me gain an advantage over my opponents. Mouse-and-keyboard players were often able to lock onto me quicker, even with a high look sensitivity and built-in aim assist. And I felt outmaneuvered and outgunned by mouse-and-keyboard players in the fastest-paced fights. But the controller’s precision TMR thumbsticks made it easy to quickly lock my crosshairs onto enemies and mow them down from afar with light machine guns or sniper rifles in long-range battles.

I also find it useful for games like Battlefield that have a lot of buttons to micromanage during moment-to-moment gameplay. If you want to swap your fire mode from automatic to single-fire, mount your weapon’s bipod against a flat surface or pull out an invaluable class gadget, you’ll be reaching across your keyboard to do so. The six remappable buttons on the Wolverine V3 Pro 8K PC are great for these situations; I loved that I could tap fire my hulking light machine gun by gripping one of the controller’s back paddles.

The controller really shone for vehicle combat, though. I found myself gravitating toward my mouse and keyboard for infantry gunplay, but anytime I’d jump into a tank, I’d reach across my desk and grab the Wolverine again. Having pressure-sensitive triggers helps with any in-game driving: A slight squeeze lets me cautiously move forward, scanning for enemy mines, while fully pulling the trigger down helps me speed out of dangerous situations. Rebinding automatic repair jobs and weapon switches to the back paddles also helped me focus more on in-game combat, which helped me keep my armored vehicles in the fight for longer. With my DualSense controller, I’d have to awkwardly fumble with the D-Pad to activate my vehicle abilities. The Wolverine controller is the definitive way for a Battlefield tank enthusiast to play.

Outside of standard first-person shooter gameplay, I also found the Wolverine V3 PC controller to be handy for hero shooters — with some caveats. When I play Marvel Rivals, I mainly play tanks that require an extensive amount of ability usage but very little aim. Characters like Doctor Strange thrive when you can quickly string inputs together, and rebinding the controls to the Wolverine’s back paddles is great for that.

On the other hand, speedy divers that need to jump in and out of the enemy team’s backline and aim-intensive snipers feel tougher to play with the Wolverine controls, and I’d swap back to my mouse and keyboard whenever I wanted to switch off tank characters and fulfill another role for my team.

One game I don’t recommend the Wolverine V3 Pro PC for is ARC Raiders. While the remappable buttons make it easy to reach for healing items and grenades, losing out on the precision aim of a mouse and keyboard just isn’t worth it in a game where one death can set your progress back by several real-life hours. The controller lets me hold my own against killer ARC robots, but once real players join the mix, I’d rather use my tried-and-true PC hardware setup.

That’s not to say that the Wolverine controller is terrible for a tactical third-person shooter: The back paddles are a great way to quickly access any healing items, grenades and other consumables you’re carrying, which could be the difference between life and death. But when I have teammates depending on me to help them escape with their hard-earned loot, I just don’t trust the Wolverine controller to help me aim better than I can with my trusty mouse and keyboard.

For playing first-person shooters like Call of Duty or Apex Legends at breakneck speeds, the Wolverine V3 Pro 8K PC likely won’t replace your mouse and keyboard. But if your ideal competitive game centers on slower gunplay and long-range firefights, this is the most precise controller I’ve ever laid hands on (and you’ll receive a healthy heaping of help from aim assist to boot).

For the games I like to play, the Wolverine V3 Pro PC controller hasn’t become my primary gaming peripheral. Instead, it’s become a great situational swapout that complements my mouse and keyboard. As much as I like keeping it on deck for a long gaming session, $200 is a high price for a part-time controller.
