You're sitting there, staring at that little spinning wheel or the progress bar that hasn't budged in ten minutes. We've all been there. You hit "update" thinking it’ll be a quick sec, and suddenly your phone is a glowing brick while you're trying to remember if you had any important calls scheduled.
Honestly, the answer to how long does it take for your phone to update isn't a single number. It’s a range. Usually, you're looking at anywhere from 15 minutes to over an hour.
But why the massive gap?
It’s not just your internet speed. It’s the "invisible" stuff—the unpacking, the verifying, and the system rewriting—that really eats up the clock. If you’re jumping from a version of Android or iOS that’s two years old, your phone basically has to perform open-heart surgery on itself. That takes time.
Breaking Down the Update Timeline
When we talk about an update, it’s actually a four-stage marathon. Most people only think about the download, but that’s often the shortest part if you have decent Wi-Fi.
The Download (5–20 minutes)
This is purely about file size and your connection. A major OS jump, like moving to iOS 26 or Android 16, can be anywhere from 2GB to a whopping 15GB. If you’re on a coffee shop Wi-Fi with ten other people, expect this to crawl. On a fast home fiber connection? It’s done before you can finish making a sandwich.

Preparing and Unpacking (10–15 minutes)
Your phone doesn't just "run" the file it downloaded. It has to unzip it, check for corruption, and make sure the files are actually from Apple or Google and not some random hacker. This is heavy lifting for the processor. This is also why older phones feel like they’re taking forever; their "brain" just can't crunch the data as fast as the newest flagship.
The Actual Installation (10–30 minutes)
This is the "danger zone." Your screen goes black, the logo appears, and the phone is officially out of commission. The system is literally replacing its own foundation while it's still standing.
Post-Install Optimization (5–10 minutes)
You think it's done because you're back at your home screen, but the phone is still working. It’s re-indexing your photos, updating database structures, and making sure your apps still play nice with the new code. You’ll notice the phone feels hot or the battery drains fast for the first hour after an update. That's totally normal.
Why Some Updates Feel Like They’re Stuck
Ever noticed how a "security patch" takes five minutes but a "system update" takes an hour?
The type of update matters.
- Security Patches: These are like fixing a leaky faucet. Small, targeted, and quick.
- Point Releases (e.g., 18.1 to 18.2): These are like repainting a room. A bit more work, maybe 20 minutes.
- Major OS Upgrades: This is a full home renovation. You’re changing the plumbing and the electrical.
If you’re wondering how long does it take for your phone to update when it feels stuck, check your storage. Phones need "breathing room" to update. If your 128GB iPhone has 127GB of memes and 4K video on it, the update will crawl. The system has to constantly move files around like a sliding tile puzzle just to find space to work.
Actually, if your storage is red-lined, the update might just fail entirely. Aim for at least 10GB of free space before you even hit that button.
The Android vs. iPhone Speed Debate
There’s a weird quirk here. In 2026, many Android phones (like the Pixel 10 or Galaxy S26) use something called "Seamless Updates" or A/B partitioning.
Basically, your phone has two "slots" for the operating system. It installs the update on Slot B while you’re still using Slot A to scroll TikTok. When it’s done, it just asks you to restart. The restart takes maybe 45 seconds, and boom—you’re updated.
iPhones don't really do this. Even the newest iPhone 17 makes you sit through the "Apple logo and progress bar" screen. While the iPhone might actually process the update faster because the chips are so powerful, the "downtime" usually feels longer for Apple users.
Pro Tip: If you're an iPhone user, always do your updates at night. The "Install Tonight" feature is a lifesaver because it waits until you're asleep and the phone is plugged in.
Real Factors That Kill Your Speed
- Server Congestion: If you try to update the second a new version drops, you're competing with millions of other people. The servers get hammered. Wait 24 hours.
- Battery Life: Most phones won't even start an update if you're under 50% battery unless you're plugged in. It’s a safety feature. If the phone dies mid-install, it’s "brick" territory.
- Thermal Throttling: If your phone is hot (maybe you were just gaming), it slows down the processor to cool off. A slow processor means a slow install.
What to Do If It Actually Hangs
If it’s been two hours and the progress bar hasn't moved a millimeter, you might actually be stuck.

First, don't panic. Usually, a forced restart fixes it. On most modern phones, this involves a quick sequence of volume buttons and holding the power button. The phone will usually realize the update failed, roll back the changes, and let you try again.
But honestly? Just leave it alone for a while. Sometimes the "verifying" stage looks like a frozen screen but the phone is actually doing some incredibly complex cryptographic checks in the background.
Summary of Actionable Steps
If you want to make the process as fast as possible, do these three things:
- Clear 10GB of space. Delete the apps you don't use or offload those videos to the cloud.
- Plug it in. Even if you have 80% battery, being on a charger tells the phone it can use "High Performance" mode without worrying about power.
- Use 5GHz Wi-Fi. Stay close to your router. If you're in the backyard on a weak signal, the download will drop and restart constantly.
The next time you ask how long does it take for your phone to update, just remember it's a marathon, not a sprint. Give it 45 minutes of peace, and it'll usually reward you with a smoother, faster device.
If you're still seeing a frozen screen after an hour of zero progress, check your manufacturer's support page for the specific "Force Restart" key combo for your model. Most of the time, the second attempt goes much faster because the files are already downloaded.
