Watching your phone slow down after an update can feel like your favorite shoes suddenly getting stuck in the mud. You expect updates to make things better, but sometimes the opposite happens—your iPhone or Android device starts running slower, apps freeze, and everything feels sluggish. If you’ve wondered, “Why is my Android or iPhone phone slow?” or searched for “how to fix phone slowing down after update Android Samsung” or “Android phone running slow and freezing Samsung,” you’re not alone.
In this post, I’m telling why your phone might slow down after a software update and, most importantly, how to fix it. These steps work whether you’re on iPhone or Android, and I’ll cover some specific fixes for Samsung and general Android devices, too. If you’ve ever browsed “how to fix phone slowing down after Android update Reddit” or “how to speed up your Android phone in 10 seconds,” you’ll find real solutions here.
Understanding Why Phones Slow Down After Updates
Many think that updates themselves are to blame for a sluggish phone. It’s easy to see why. You install the latest iOS or Android version, expecting new features, and suddenly your apps hang, the keyboard lags, or the screen just isn’t as snappy. Here’s the secret: the update alone usually isn’t the only reason for these problems.
Phones have a lot going on under the hood. When you run an update, your device may need extra time to settle in. Temporary background tasks, out-of-date apps, or old batteries can all play a part. On Android, especially with brands like Samsung, phones may re-index files, rewrite caches, and optimize apps for the new system. This can lead to a short burst of slowness
Battery Health and Its Impact on iPhone and Android Performance
On iPhone, checking Battery Health is simple:
- Go to Settings
- Tap Battery
- Select Battery Health & Charging
If your battery percentage shows 80% or lower, your phone likely can’t deliver the peak performance you expect. A pop-up or message may warn you that your battery’s health has reached its limit, pointing you toward a replacement at an Apple service center.
For Android and Samsung, finding battery health details can be more basic, but third-party apps offer insights. Look for signs like fast battery drain, random shutdowns, or performance drops when unplugged. Newer Samsung phones sometimes provide battery info under Settings > Device care > Battery.
Why Battery Health Matters
As a phone’s battery ages, it loses the ability to deliver full power, especially during demanding tasks. If you’ve owned your phone for over two years, this becomes more likely. As battery capacity slips, performance suffers. Apps take longer to open, the home screen lags, and even simple scrolling can feel off. This issue is common after updates, as new software sometimes demands more power.
If you know your battery health is dipping (below 80% for iPhone or experiencing symptoms on Android), replacing the battery is the smartest move. Apple makes this process straightforward for iPhones, and Samsung users can visit an authorized center or a trusted phone repair shop.
What to Expect After Battery Replacement
If you swap in a fresh battery, you’ll likely see:
- Faster app launch times
- Smoother navigation between screens
- Fewer crashes and random restarts
- Longer battery life across the day
Temporary Post-Update Tasks That Slow Down Your Phone
After a major iOS update, your iPhone kicks off a handful of tasks in the background. These include reorganizing (indexing) your files so the Spotlight search tool works fast. iPhones also scan and update your photo library for new search features or facial recognition, which can temporarily weigh the system down.
iCloud and Background Uploads
If you use iCloud Photos, a big update may trigger new photo uploads or optimize files in the background. Android users see the same with Google Photos or Samsung Cloud. These processes are helpful—but they can slow things down while they finish.
How Long Does This Last?
These slowdowns are temporary. For most users, background tasks wrap up within a few days to a week. You might notice your phone feels slow or your apps hesitate during this time. In almost every case, just using your phone as usual will bring it back to normal as these tasks complete.
The Effect of Low Power Mode on Performance
Low Power Mode on iPhone, and its equivalent on Android (sometimes called Battery Saver), is designed to help you limp through to the next charge. It limits background services, updates, and system speed to keep the lights on.
When Low Power Mode Gets in the Way
If you leave Low Power Mode on all the time, your phone’s performance will dip. You’ll see lag, frozen apps, and slower animation, especially on older or lower-refresh-rate screens like the 60 Hz on some iPhones and mid-tier Samsung devices. To rule this out, turn off Low Power Mode and use your phone for a couple of days to see if things improve.
Turning Off Low Power Mode
On iPhone:
- Open Settings
- Tap Battery
- Toggle Low Power Mode: OFF
On Android/Samsung:
- Go to Settings
- Tap Battery and device care or Battery
- Turn off power-saving mode
This can be a quick fix for a slow phone if Battery Saver has been on too long.
Essential Troubleshooting Steps for Phone Slowdown
Let’s walk through a checklist I use whenever someone asks, “How to fix a phone slowing down after an Android Samsung update?” or “How to fix a slow Android phone?”
1. Restart Your Phone
It sounds basic, but a simple restart can fix many temporary bugs. It shuts down all running background processes and resets your device memory. Always restart after a major update before diving into deeper fixes.
2. Manage Free Storage Space
A phone with little free space can get bogged down. Both iPhone and Android need room to store temporary files and cache.
- Aim for at least 5 to 10 GB of free space
- Back up photos and videos to cloud options:
- iCloud
- Google Photos
- Local storage on your computer
- Delete unused apps, old messages, and large files
When storage tightens, you’ll see freezes, delayed app openings, and poor overall speed.
3. Update Your Apps
App developers roll out updates to fix bugs after new operating system releases. Outdated apps may not play well with the latest iOS or Android version, leading to slow performance, crashes, or freezing.
To update on iPhone:
- Open App Store
- Tap your profile picture (top right)
- Scroll to see pending updates, then Update All
On Android/Samsung:
- Open Google Play Store
- Tap your profile picture, then Manage apps & device
- Tap Updates available, then Update all
Do this while connected to Wi-Fi or solid mobile data (5G recommended).
4. Use Reduce Motion for Smoother Performance (Optional)
iPhone users can turn on Reduce Motion, which dials back fancy animations:
- Go to Settings
- Tap Accessibility
- Select Motion
- Toggle on Reduce Motion
This helps if your iPhone is choppy between screens, especially when battery health is low.
Android users have similar options under Developer settings or Accessibility to reduce animations or transitions, which can help with lag.
5. Reset All Settings
Resetting all settings can fix stubborn software bugs. Don’t worry, this keeps your photos, files, and apps safe—it only resets system settings like Wi-Fi passwords and wallpaper.
On iPhone:
- Go to Settings
- Tap General
- Scroll down to Transfer or Reset iPhone
- Tap Reset
- Select Reset All Settings
Don’t tap Erase All Content and Settings unless you want a full factory wipe!
On Android/Samsung:
- Go to Settings
- Tap General management
- Tap Reset
- Choose Reset settings
Only use the factory data reset if nothing else works and you have a full backup.
Advanced Fix: iOS or Android Restore
When to Consider a Restore
If you’ve tried all the steps above and your phone is still limping along, a full restore can help. This is especially useful for deep software issues that don’t go away with restarts or resets.
How to Restore Your Device
iPhone:
If your iPhone is still under warranty, make an appointment with your nearest Apple service center. They’ll restore your device’s software for you. If you’re out of warranty, restoring your iPhone at home is possible with a laptop or Mac—just be sure to back up all important data to iCloud, iTunes, or Finder first.
Android/Samsung:
Samsung and other Android users can perform a factory reset through Settings. Again, always back up everything first—use Google Drive, Samsung Cloud, or your computer. After restoring, your phone will start fresh, usually clearing out any stuck software bugs.
Why a Restore Works
A system restore:
- Wipes out deep software errors
- Gets rid of hidden corrupt files or old system caches
- Returns your phone to its newest, clean state
