Phones are reliable until they aren't. One second you're scrolling through a recipe or mid-tweet, and the next, your iPhone is a high-end glass brick that won't respond to a single touch. It happens. Honestly, even the newest iPhone 16 or 15 Pro Max models with all that computational power can occasionally hit a software snag that locks the entire UI. When that happens, you aren't looking for a "factory reset"—you don't want to lose your photos—you're looking for a hard reset, or what Apple technically calls a "force restart."
It's a hardware-level override. You're basically cutting the power for a split second to force the processor to start over.
How to Hard Reset an iPhone Without Losing Your Data
Most people panic and think they’ve broken the screen. They haven't. Usually, it's just a kernel panic or a background process that’s stuck in an infinite loop, hogging the CPU. To fix this on any modern iPhone—meaning anything from the iPhone 8 all the way up to the latest iPhone 15 and 16 lineups—you have to perform a specific "button dance."
It’s a three-step rhythm. First, you’re going to quickly press and release the Volume Up button. Immediately after that, do the exact same thing with the Volume Down button. Finally, you have to press and hold the Side button (the one on the right).
Don't let go.
Seriously, people always let go too early because the "Slide to Power Off" bar appears. Ignore that bar. If your screen is frozen, you couldn't slide it anyway. Keep holding that side button until the screen goes pitch black and the silver Apple logo finally pops back up. Only then should you release your grip. If you did it right, your phone is rebooting its firmware from scratch.
Why the Buttons Changed Over the Years
If you’re digging an old iPhone 7 out of a drawer, that three-button sequence won't work. Apple changed the hardware architecture around 2016. On an iPhone 7 or 7 Plus, you actually have to hold the Volume Down and the Sleep/Wake button simultaneously.
Why?
Because the Home button on the 7 wasn't a real button. It was a solid-state piece of glass that used haptic feedback to mimic a click. If the software crashed, that "button" wouldn't register a press, so Apple had to move the hard reset command to physical buttons that actually clicked.
And if you’re a real nostalgist using an iPhone 6s or an original SE? You’re back to holding the Home button and the Top (or Side) button at the same time. It’s simpler, but those mechanical home buttons were notorious for wearing out after a few years of heavy use.
The Difference Between a Hard Reset and a Factory Reset
There is a massive amount of misinformation online about this. You’ll see "hard reset" used interchangeably with "factory reset" on sketchy tech forums.
They are not the same thing.
A hard reset is like pulling the plug on a desktop computer and plugging it back in. It clears the temporary cache and stops all active processes. Your photos, your weirdly specific alarm clock settings, and your open browser tabs (mostly) stay right where they were.
A factory reset is the "nuclear option." That’s where you go into Settings > General > Transfer or Reset iPhone and wipe every single byte of data off the device. You only do that if you're selling the phone or if the software is so corrupted that a standard reboot won't fix the "White Screen of Death."
If your iPhone is just acting "glitchy"—maybe the Wi-Fi keeps dropping or the keyboard is lagging—a hard reset is usually the first thing a technician at the Genius Bar will try. It’s the "have you tried turning it off and on again" of the smartphone world, just more forceful.
When a Hard Reset Won't Save You
Sometimes the hardware is actually the problem. If you dropped your phone in a pool and now it’s looping the Apple logo, a hard reset might actually make things worse by trying to power up components that are short-circuiting.
According to repair experts at iFixit, if a hard reset results in a screen that shows a laptop icon and a cable (Recovery Mode), your iOS firmware is likely corrupted. At that point, you're going to need a Mac or a PC with iTunes to "Restore" the device. It’s a bummer, but it’s better than having a dead device.
Also, keep in mind that a hard reset doesn't fix a broken digitizer. If your screen is physically cracked and doesn't respond to touch, forcing a reboot won't magically reconnect those severed touch-sensitive layers. You'll just reboot to a screen that is still broken.

Critical Troubleshooting Steps
If you’ve tried the Volume Up, Volume Down, and Side button combo and nothing happened, check your case. Seriously.
I’ve seen dozens of people think their phone was dead when, in reality, their thick ruggedized case was preventing the buttons from fully depressing. Take the case off. Try again on the bare metal.
Another common issue is timing. You have to be quick. If you wait more than a second between the Volume Up and Volume Down presses, the iPhone thinks you’re just trying to change the ringer volume. It won't trigger the reset sequence. It’s a brisk tap-tap-hold motion.
- Check your charging port: If the phone is dead and won't hard reset, it might just be out of juice. If the port is full of pocket lint, the cable won't seat properly.
- Use a wall outlet: Don't try to charge a frozen phone from a laptop USB port; those often don't provide enough amperage to "jump-start" a completely frozen battery management system.
- Give it time: Sometimes a phone is so overwhelmed that it takes 20 or 30 seconds of holding that Side button before the Apple logo appears. Be patient.
Hard Resetting Your iPhone is the First Step to Recovery
Most iPhone issues are transient. They are ghosts in the machine caused by a bad app update or a memory leak in Safari. Knowing how to hard reset an iphone is basically a survival skill for the 21st century. It saves you a trip to the mall and a long wait for a technician to tell you exactly what I just told you.
If the hard reset works but the phone freezes again within ten minutes, you probably have a storage issue. iPhones hate it when they have less than 1GB of free space. They start "swapping" memory in a way that causes massive system-wide hangs. Once you get back into your phone, go to Settings > General > iPhone Storage and delete those four-year-old videos of fireworks you’re never going to watch again.
If you find yourself having to hard reset your iPhone every single day, it's time to look at your battery health. Once a lithium-ion battery degrades below 80% of its original capacity, it can’t always provide the "peak power" the processor needs during heavy tasks. This causes the phone to shut down or freeze as a safety measure. You can check this in Settings > Battery > Battery Health & Charging. If it says "Service," a hard reset is just a temporary bandage on a hardware problem.
Actionable Next Steps:
- Practice the sequence now: Don't wait until your screen is frozen to learn the Volume Up, Volume Down, Side Button rhythm. Try it while the phone is working so you know what the "click" feels like.
- Back up your data immediately: If your phone just froze for the first time, take it as a warning shot. Plug it into your computer or trigger an iCloud backup right now.
- Update your software: After a successful hard reset, check for an iOS update. Apple frequently releases patches specifically to fix the "hangs" that make hard resets necessary in the first place.
- Clean your buttons: Use a toothpick or a soft brush to ensure there isn't gunk around the Side button that might prevent it from being held down for the required 15-20 seconds.
