The message pops up just as you’re about to fall asleep: “Software update ready to install.” “Do you want to restart now?”
You sigh, hit “Later,” put the phone down on the nightstand, and turn over. The screen lights up for a second and then goes dark, but the device in your hand is still very much alive and connected to the world, the network, and anyone who might be quietly listening in the background.
People in windowless rooms in Washington are worrying about that exact moment on the other side of that tiny screen.
They want you to hit the restart button.
A lot.
Why US spies are suddenly interested in the power button on your phone
US intelligence agencies have been giving people the same surprisingly simple advice for the last few years: turn your phone off and on again. Not once in a blue moon, but all the time.
It sounds almost old-fashioned, like someone telling you to “blow on the cartridge” in the Nintendo days, for iPhone and Android users who are used to just plugging in at night and never turning off.
But for people whose job it is to hunt down hackers and foreign spies, this small act has become a secret line of defence.
In a world full of very advanced surveillance tools, this is a small, low-tech habit.
The warning didn’t come from a weird blog or a Reddit thread full of paranoid people. It came from the NSA and the FBI, who gave briefings to journalists, policymakers, defence contractors, and even business leaders.
“Zero-click” and “zero-day” exploits are the names of the attacks that worry them. These attacks get into your phone without you having to tap on a single link that looks suspicious.
A US official put it in a way that was both clear and tired: a phone can be hacked by getting the wrong kind of message or call from someone who knows exactly how to get around the software’s security holes.
You can’t see it or feel it, but the door is suddenly open.
What does rebooting have to do with all this?
Many of these super-secret tools only live in your phone’s temporary memory (RAM), so they can disappear without leaving any obvious signs. They are made to be hidden, not unbreakable.
That short-term memory is erased when you restart.
It won’t fix every threat, and it won’t magically clean a device that has already been fully taken over, but for a lot of high-end spyware, a simple reboot is like pulling the rug out from under the intruder’s feet.
A small ritual that quietly sets the stage again.
How a weekly restart became a common security practice
Some employees of US federal agencies are now told to restart their phones at least once a week. That’s not just a tip for people who work in intelligence, defence, or diplomacy; it’s the law.
One senior staff member said that doing it was like how people used to check the doors at night: walk the dog, lock the door and restart the phone.
The logic is brutally simple. You can’t fix every bug as soon as you find it. You can, though, interrupt the kind of malware that depends on staying quietly loaded in memory, patiently watching, listening and sending data out.
Think of the Pegasus scandal, that infamous spyware developed by NSO Group and used on politicians, activists, lawyers and journalists across the globe. Investigations showed that some of these tools landed via missed calls or invisible iMessage exploits, then sat inside phones like ghosts.
There was no pop-up, no sketchy app, and nothing else that was obvious.
Security researchers who looked into these attacks found something interesting. Some infections needed tricks to stay alive after a restart. Others simply died when the phone rebooted, forcing attackers to reinfect the target again and again.
Suddenly, the humble “power off, power on” looked less like superstition and more like friction attackers really hated.
For intelligence agencies, that friction has value. Every forced reinfection leaves more traces, more chances for detection, more opportunities to update defenses.
From their point of view, your weekly reboot is like sweeping the stage before the bad actors have finished their play.
This doesn’t mean you’re personally on a government hit list. Most people never will be.
But the tools built for high‑value targets have a way of trickling down: from governments to private firms, from elite hackers to criminal gangs. What starts in national security often ends up in everyday cybercrime.
So the advice leaks out of classified briefings and lands softly in public recommendations.
How to reboot smarter—and what not to expect from it
So what does “regularly” mean in real life? For most of us, once a week is the sweet spot. Not obsessively every hour, not only when your phone freezes on a busy day.
Pick a moment that already exists in your routine: Sunday night after laundry, Friday after work, or that half‑awake scroll before bed.
On iPhone, hold the side button and a volume button, swipe to power off, wait a few seconds, then turn it back on. On Android, a long press on the power button usually brings up restart or power‑off options.
Nothing fancy. Just a clean shutdown, a brief pause, then a fresh boot.
The trap is thinking this turns your phone into a fortress. It doesn’t. Rebooting is one layer, in a world where attackers stack several. Some malware can survive restarts, live in system partitions or sneak in again through the same door if your software is never updated.
That’s why agencies pair the reboot advice with another mantra: keep your system and apps updated.
Let’s be honest: nobody really does this every single day.
You ignore some alerts, delay some updates, forget the rest.
That’s human. The realistic goal isn’t perfection, it’s raising the cost for someone who wants inside your digital life.
The people giving this advice know you’re not a full‑time security expert. They also know attackers often go for the easiest possible win.
“We’re not asking people to live like they’re in a spy movie,” one former US cyber official told me. “We’re asking them to take the steps that make them the least convenient target in the room.”
Alongside regular reboots, their informal checklist tends to look like this:
- Update iOS/Android and your main apps as soon as practical
- Use a strong screen lock (PIN, pattern, or biometric)
- Turn on automatic backups and two‑factor authentication for key accounts
- Be picky with links and attachments, even from people you know
- Review which apps you’ve installed and what permissions they hold
*The reboot is the easy one, the low‑friction habit that opens the door to taking the others a bit more seriously too.*
What this tiny habit says about the phones we live inside
There’s something quietly revealing about this whole story.
The most powerful intelligence agencies in the world, with budgets we can barely imagine, are telling ordinary people to use the same button they use when a device just “acts weird.”
It’s a reminder that our phones are no longer just phones. They’re microphones, trackers, diaries, wallets, photo albums, workstations and confidants, all crushed into a slab of glass that never really sleeps.
When that much of you is in one place, even a two‑second press on the power button becomes a small act of self‑defense.
This advice also strips away a bit of the techno‑mystique around cybersecurity. You don’t need to understand every exploit or memorize every acronym to play a part in your own protection. You need a few grounded habits, repeated often enough that they feel boring.
We’ve all been there, that moment when you realize your whole life is wrapped inside a device you drop, forget on a café table, or scroll half‑awake at 2 a.m.
Maybe that’s the real point US agencies are nudging toward: not panic, not paranoia, but a slightly sharper awareness. The sense that pressing “restart” isn’t just about fixing a glitch, it’s about quietly reminding yourself who should be in control of this screen—and who shouldn’t.

| Weekly rhythm is a realistic target | Link the reboot to an existing habit, like Sunday night or payday | Makes security feel doable without becoming an exhausting routine |
| Rebooting is just one layer of defense | Needs to be combined with updates, strong locks and cautious clicking | Helps you build a balanced, real‑world security posture around your phone |
FAQ:
- Do I really need to reboot if my phone already feels fast and stable?
Yes. Performance and security aren’t the same thing. Your phone can feel smooth and quick while still hosting code that quietly spies on you in the background.
- Isn’t airplane mode enough to block attackers?
Airplane mode cuts connections while it’s on, which can slow or stop data being sent out. Once you turn it off, though, any malware that survived is still there, ready to reconnect.
- Can a reboot remove all types of malware?
No. Some infections can survive restarts by digging deeper into the system. Rebooting is especially effective against certain memory‑only or poorly designed tools, not against everything.
- How often should a normal user restart their phone?
For most people, once a week is a solid balance between convenience and protection. High‑risk users—journalists, activists, sensitive jobs—may choose to do it more often.
- Does turning the screen off count as a reboot?
No. Locking or turning the screen off doesn’t clear memory or stop running processes. You need a full power off / restart cycle for the security benefits intelligence agencies are talking about.
