The iPhone 7 is kind of a relic now, but honestly, it’s still one of the most resilient pieces of hardware Apple ever pushed out of Cupertino. If you’re holding one today, you’re likely dealing with a device that has seen some things. Maybe the screen is spider-webbed, or the battery dies if you even look at a YouTube video for more than five minutes. But the real headache? That tiny mechanical clicker on the right side. Knowing how do you the sleep button on iPhone 7 isn't just about turning the screen off; it's about navigating a device that was the first to ditch the mechanical home button, making that side button your primary lifeline for everything from screenshots to emergency resets.
It's actually on the right side. Unlike the older SE or the 5s, where it sat on top like a little hat, the iPhone 7 moved it to the side to make it easier to reach with your thumb. Apple officially calls it the "Side button," but we all just call it the sleep button. You press it once to lock the phone. You hold it to turn the thing off. But when it stops clicking, or when it gets "mushy," that’s when the real fun starts.
The Side Button: More Than Just a Lock Switch
Most people think the sleep button is a one-trick pony. It isn't. On the iPhone 7, this button is the gatekeeper for the Power Off slider. You have to hold it down for about three to five seconds before that "slide to power off" text appears. If you just tap it, the screen goes dark. If you double-tap it while on the lock screen, you might accidentally pull up Apple Pay if you have that configured, which is a classic "oops" moment when you're just trying to put the phone in your pocket.
Interestingly, the iPhone 7 was a massive turning point for Apple's haptics. While the home button became a "fake" solid-state piece of glass that vibrated to mimic a click, the sleep button remained a physical, mechanical switch. This creates a weird tactile dissonance. You press the home button and feel a Taptic Engine buzz, but you press the sleep button and feel a genuine mechanical "ka-tink." Because it's a moving part, it’s prone to failure. Dust, pocket lint, or just five years of aggressive clicking can jam the internal bracket. When that happens, you’re basically locked out of your own tech.
Hard Resetting Without a Home Button
This is where things get tricky for people upgrading from older models. On an iPhone 6, you’d hold the home button and the sleep button to force a restart. On the iPhone 7, that does absolutely nothing. Because the home button is software-controlled, it won't respond if the OS has crashed. To force a restart on the iPhone 7, you have to hold the Sleep Button and the Volume Down button simultaneously. You keep holding them until the Apple logo pops up. It feels unnatural the first time you do it, like you're trying to perform a secret handshake with a piece of aluminum.
What Happens When the Sleep Button Actually Breaks?
It's a nightmare. Truly. If your sleep button stops responding, you can’t lock your phone manually. You have to wait for the "Auto-Lock" timer to kick in, which drains your battery. Even worse, you can't easily turn the phone back on if it dies.
There's a savior, though. It's called AssistiveTouch.
If you're stuck, you have to go into Settings, then Accessibility, then Touch. Turn on AssistiveTouch. A little grey floating circle appears on your screen. You can program this little guy to act as your virtual sleep button. You tap it, hit "Device," and there is a "Lock Screen" icon. It’s a clunky workaround, but it beats spending $150 on a repair for a phone that’s probably worth $80 on a good day.

Actually, let's talk about the repair side. If you take an iPhone 7 to a shop because the sleep button is stuck, they aren't just replacing a button. They’re replacing a ribbon cable. That cable also controls the volume buttons and the mute switch. It’s all one interconnected nervous system inside the chassis. If you're a DIY type, be warned: replacing that cable requires taking out almost every single component, including the logic board. It’s a 2/10 on the "easy to fix" scale. Most people end up just living with the floating on-screen button until they finally trade the phone in for a newer model.
Dealing with "Mushy" Buttons
Sometimes the button isn't broken; it's just dirty. We take our phones everywhere—gyms, kitchens, beaches. Gunk gets in the cracks. A tiny bit of high-percentage isopropyl alcohol (90% or higher) on a Q-tip can sometimes save your life here. You dab it around the edges of the button and click it repeatedly. The alcohol dissolves the oils and sugar (from that spilled soda, let's be honest) and evaporates without shorting the electronics.
Software Gremlins and the Sleep Button
Sometimes you think the button is broken, but it's actually iOS being weird. There’s a rare bug where the phone thinks the button is being held down constantly. This leads to the phone boot-looping—turning on and off forever. Or, the phone might refuse to wake up when you click it.
Before you panic and buy a new phone, try a "Reset All Settings." It doesn't delete your photos, but it flushes out the weird configuration bugs that might be preventing the sleep button from communicating with the processor. It’s a pain to put your Wi-Fi passwords back in, but it’s better than a dead phone.
Another weird quirk? The iPhone 7 was the first "water-resistant" iPhone (IP67). This means there’s a rubber gasket around the sleep button. If that gasket rots or gets displaced, the button might feel "stiff." This is actually a sign that the water resistance is compromised. If your button feels like it’s fighting you, keep that phone away from the sink.
The Screenshot Dilemma
We use the sleep button for screenshots constantly. On the iPhone 7, it's the classic combo: Sleep Button + Home Button. But because the iPhone 7 home button requires the phone to be "awake" to register a click, sometimes you'll find yourself just locking the phone instead of taking the shot. The trick is a simultaneous, quick tap. Don't linger. If you hold the sleep button a fraction of a second too long, the power-off screen starts to ghost in.

Actionable Steps for a Failing Button
If you’re currently struggling with how do you the sleep button on iPhone 7 because the hardware is failing, stop stressing and follow this triage list.
- Enable AssistiveTouch immediately. Go to Settings > Accessibility > Touch > AssistiveTouch. This ensures you aren't stranded if the button dies completely tonight.
- Clean the crevice. Use a toothpick to gently (very gently) scrape around the button housing. You'd be surprised how much pocket lint can pack into a sub-millimeter gap.
- Check your case. This sounds silly, but cheap silicone cases often lose their rigidity. Sometimes the "button" on the case isn't actually making contact with the button on the phone. Take the case off and try the button "naked" to rule out a physical obstruction.
- Adjust Auto-Lock. Go to Settings > Display & Brightness > Auto-Lock and set it to 30 seconds. This way, if you can't manually press the sleep button to lock the screen, the phone will do it for you quickly, saving your battery and your privacy.
The iPhone 7 is a tank, but even tanks have weak spots. The side button is the mechanical Achilles' heel of this specific era of Apple design. Treat it gently, keep it clean, and keep AssistiveTouch in your back pocket as a digital insurance policy. If the button is truly dead and you aren't ready to upgrade, that floating grey dot is going to be your new best friend for the foreseeable future. Use it to lock the screen, take screenshots, and even trigger Siri without ever needing to exert physical pressure on the hardware itself.
