Most Common iPhone Problems and How to Fix Them
iPhones are built to last, but no device is immune to wear, drops, or the occasional software hiccup. Whether it’s a screen that won’t respond to your touch or a battery that seems to have a mind of its own, most iPhone issues fall into a handful of predictable categories. Knowing what’s actually happening can save you time, money, and a fair bit of frustration.
Here’s a look at the most common iPhone problems people bring into iFix Technology in Vancouver, along with practical ways to fix them.
1. iPhone Touch Screen Not Working
Few things are more disruptive than an iPhone touch screen not working, especially when the rest of the phone still turns on and looks fine. This usually shows up as dead zones where taps don’t register, a screen that responds erratically, or a display that ignores your touch entirely.
Common causes:
- A cracked or damaged digitizer (the touch-sensing layer beneath the glass)
- A loose or damaged connector cable inside the phone
- Software bugs following an iOS update
- A cheap or poorly fitted screen protector interfering with sensitivity
What to try first: Restart the phone, remove any screen protector, and test again. If the screen was recently dropped or shows visible cracking, the issue is almost certainly hardware. For a closer look at how touch failures develop and what to check before booking a repair, our guide on touch screen not working covers it in more depth. In most hardware cases, a full screen replacement is the only lasting fix.
2. Problems With the Home Button on iPhone
Older iPhone models with a physical Home button (iPhone 6 through 8, and the SE series) commonly develop button issues over time. A problem with the home button on an iPhone can show up as a button that feels stiff, doesn’t respond every time you press it, or stops registering fingerprint scans through Touch ID altogether.
Common causes:
- Dust and debris trapped around the button over years of use
- A worn-out mechanical switch beneath the button
- Loose internal flex cable connections
- Liquid exposure affecting the button’s sensor
What to try first: Clean gently around the edges of the button with a dry, soft brush, and check that Touch ID is still enabled in Settings. If the button feels physically unresponsive or Touch ID has stopped recognizing your fingerprint consistently, the internal switch or cable likely needs replacing. This falls under detailed hardware work, which our other repairs service handles for older iPhone models.
3. iPhone Turning Off Randomly
An iPhone turning off randomly, even with battery life remaining, is one of the more alarming issues owners deal with. One moment the phone shows 30% or more, the next it’s completely off and won’t turn back on without being plugged in.
Common causes:
- A battery that can no longer supply consistent power under load, especially in cold weather
- A loose battery connector following a previous repair or drop
- Corrosion or damage from past liquid exposure
- A software fault causing the phone to crash and shut down
What to try first: Check your battery health under Settings > Battery > Battery Health & Charging. If it shows a “Peak Performance Capacity” warning or a percentage well below 100%, degraded battery health is the likely cause. A battery replacement resolves this in the vast majority of cases. If the phone has ever been exposed to moisture, it’s worth having it checked for water damage as well, since corrosion can cause the exact same random shutdown pattern.
4. Slow Charging or Charging That Won’t Start
Charging problems are another frequent complaint, ranging from a phone that charges painfully slowly to one that won’t charge no matter how it’s plugged in. If your phone is filling up more slowly than it used to, our breakdown of common reasons your phone takes too long to charge walks through the usual culprits. If charging has stopped working entirely, our guide on common reasons your phone won’t charge covers that scenario in detail, including how a damaged charging port is often to blame.
5. Cracked or Damaged Screens
A cracked screen doesn’t just look bad, it can affect touch accuracy, display colour, and even let dust and moisture into the phone over time. Even a small hairline crack tends to spread with continued use, eventually leading to bigger problems. If your screen has taken a hit, our guide on how to fix a cracked screen explains what to check before deciding on a repair.
6. Software Glitches and Freezing
Not every iPhone problem is physical. Frozen apps, unexpected restarts, and sluggish performance are often tied to outdated iOS versions, a nearly full storage drive, or a buggy update. Before assuming the worst, try restarting the phone, freeing up storage, and installing the latest software update. If problems persist across multiple apps or after a fresh restart, the issue may point to a deeper hardware fault rather than software alone.
When to See a Professional
Many iPhone issues, particularly anything involving the touch screen, Home button, battery, or charging port, are hardware problems that get worse the longer they’re left alone. A screen that’s partially unresponsive today can fail completely next week. A battery causing random shutdowns will continue to degrade rather than recover on its own.
At iFix Technology, we diagnose the exact cause before recommending a repair, so you’re never paying for guesswork. Our technicians use quality parts and back every repair with a warranty, with most jobs completed the same day.
