We’ve seen thousands of phones come through our repair shops in Singapore, and unfortunately, many arrive in worse condition than they needed to be. Why? Because well-meaning owners made common mistakes that turned a simple repair into a complex (and expensive) problem.
This guide reveals the top 10 phone repair mistakes we see daily, so you can avoid them and save time, money, and stress.
Mistake #1: Waiting Too Long to Get Repairs
What happens: You crack your screen but think “I’ll wait until it gets worse.” Or your battery drains fast but you just carry a power bank everywhere. Small problems become big problems.
Why it’s bad:
- Small screen cracks spread across entire screen
- Singapore humidity causes moisture to seep through cracks, damaging internals
- Degraded batteries can swell—which is dangerous
- Problems that cost $80 today could cost $300 next month
Smart approach: Get repairs done as soon as issues appear. Most repairs take just 30-60 minutes.
Mistake #2: Attempting DIY Repairs Without Proper Knowledge
What happens: You watch a YouTube video and think “I can do this!” You order cheap parts from Shopee/Lazada and start disassembling your phone.
Why it’s bad:
- Modern phones have delicate ribbon cables that tear easily
- Face ID/Touch ID sensors are paired to your phone—damage them and they’re permanently disabled
- Adhesives require specific temperatures and techniques
- Cheap replacement parts often fail within weeks
- You void warranty (if still under warranty)
- Repair shops charge MORE to fix DIY disasters
Real example: Customer bought $30 iPhone screen online, damaged Face ID connector during DIY installation. Repair quote went from $150 (screen) to $500 (screen + Face ID module, which can’t be replaced).
Smart approach: Unless you have experience and proper tools, leave it to professionals. The $80-150 you “save” isn’t worth the risk.
Mistake #3: Using Hair Dryers on Water-Damaged Phones
What happens: Your phone gets wet. Someone says “use a hair dryer to dry it!” You blast it with hot air.
Why it’s terrible:
- Heat melts internal adhesives and damages components
- Forced air pushes water DEEPER into the phone
- Can cause battery to swell or catch fire
- Creates hot spots that damage circuits
Smart approach: Turn off phone immediately. DON’T try to turn it on. DON’T charge it. Bring it to repair shop ASAP for professional ultrasonic cleaning. Read our complete water damage guide.
Mistake #4: Choosing Repair Shop Based on Price Alone
What happens: You see “$50 iPhone screen repair!” and rush to the cheapest shop without checking reviews or quality.
Why it’s risky:
- Cheapest shops often use Grade C or fake parts
- Poor-quality screens have: dead pixels, dim display, ghost touches, inaccurate colors
- No warranty or “90-day warranty” that’s never honored
- Inexperienced technicians who damage other components
- You end up paying twice: once for cheap repair, again for proper repair
Smart approach: Check reviews, ask about parts quality (Grade A?), verify warranty terms. A repair that costs $120 and lasts vs $60 that fails in 2 months is a better deal.
Mistake #5: Not Backing Up Data Before Repair
What happens: You drop off your phone for repair without backing up. During repair, something goes wrong and data is lost.
Why it’s a problem:
- While rare, accidents happen—data loss is possible
- Screen repairs, battery replacements usually safe for data
- Motherboard repairs carry higher data risk
- Photos of kids, business documents, years of messages—irreplaceable
Smart approach:
- iPhone: Settings > Your Name > iCloud > iCloud Backup > Back Up Now
- Android: Settings > Google > Backup > Back up now
- Take 5 minutes to backup before any repair
Mistake #6: Continuing to Use a Damaged Phone
What happens: Your screen is cracked, so you just put tape over it and keep using it for months. Or your battery swells but you ignore it.
Why it’s dangerous:
- Cracked screens: Cuts on fingers, moisture damage to internals, spreads further
- Swollen batteries: Can catch fire or explode (YES, really!)
- Broken charging ports: Can cause electrical shorts
- Loose components: Rattling parts can damage other components
Smart approach: If there’s visible damage or swelling, get it repaired ASAP. Don’t gamble with safety.
Mistake #7: Believing the “Rice Method” Fixes Water Damage
What happens: Phone gets wet. Everyone says “put it in rice!” You bury your phone in rice for 2 days, then try turning it on.
Why it’s inadequate:
- Rice absorbs moisture from AIR, not from inside your phone
- Rice dust gets inside phone openings
- Water leaves mineral deposits that cause corrosion—rice doesn’t fix this
- Corrosion develops quickly in Singapore’s humidity
- By the time you “try” rice for 48 hours, corrosion has set in
Smart approach: Skip rice entirely. Bring wet phone to repair shop immediately for ultrasonic cleaning and proper drying. Every hour you wait makes damage worse.
Mistake #8: Not Asking About Warranty Before Repair
What happens: You get your screen repaired. Two weeks later, it develops issues. Shop says “sorry, no warranty.”
Why it matters:
- Reputable shops offer 30-90 day warranty
- No warranty = no confidence in their work
- Warranty should cover parts AND workmanship
- Get warranty terms in writing
Smart approach: Before paying, confirm: (1) How many days warranty? (2) What’s covered? (3) What voids warranty? Get receipt with warranty terms.
Mistake #9: Ignoring Warning Signs of Failing Batteries
What happens: Your phone battery drains fast, overheats, or shuts down randomly. You think “it’s just old” and keep using it.
Why it’s problematic:
- Degraded batteries affect phone performance (iOS/Android throttle CPU to prevent shutdowns)
- Can cause unexpected shutdowns when you need phone most
- Risk of swelling and fire if left too long
- You’re carrying power banks constantly when $50-80 battery replacement would solve it
Smart approach: If battery health below 80% or you notice these warning signs, get it replaced. Don’t wait.
Mistake #10: Accepting Repair Without Understanding What’s Wrong
What happens: You bring phone for screen repair. Technician says “you also need to replace the charging port and clean the motherboard for $300 more.” You accept without questioning.
Why it’s risky:
- Some shops upsell unnecessary repairs
- You might be paying for problems that don’t exist
- Should understand exactly what’s being fixed and why
Smart approach:
- Ask: “Can you show me what’s wrong?”
- Ask: “What happens if I don’t fix this extra issue?”
- Ask: “Can I just do the screen first and decide on other repairs later?”
- Get itemized quote in writing
- Get second opinion if quote seems excessive
Red Flags to Watch For at Repair Shops
Avoid shops that:
- Won’t give you a price estimate upfront
- Say they need to keep your phone for 5-7 days (most repairs take hours, not days)
- Don’t offer any warranty
- Have terrible reviews online
- Pressure you to agree to extra repairs immediately
- Won’t show you the problem or explain what they’re fixing
- Only accept cash (no receipts)
- Are significantly cheaper than all other shops (suspiciously cheap)
What to Look For in a Good Repair Shop
- 4.5+ stars on Google Reviews with hundreds of reviews
- Clear pricing listed or quoted upfront
- 30-90 day warranty on repairs
- Physical storefronts (not just mobile service)
- Experienced technicians (ask how long they’ve been repairing)
- Proper receipts with warranty terms
- Free diagnostics offered
- Reasonable turnaround (30-60 minutes for simple repairs)
